Such binding molecules include T cell receptors (TCRs) and antigen-binding fragments thereof and antibodies and antigen binding fragments thereof that exhibit antigenic specificity for binding or recognizing a peptide epitope of HPV 16 E6 or HPV 16 E7. Also provided in some embodiments are nucleic acid molecules encoding the binding molecules, engineered cells containing the binding molecules, compositions and methods of treatment involving administering such binding molecules, engineered cells or compositions.

(39) HPV is a causative organism in most cases of cervical cancer and has been implicated in anal, vaginal, vulvar, penile, and oropharyngeal cancers, and other cancers. Generally, the HPV genome contains an early region containing six open reading frames (E1, E2, E4, E5, E6 and E7), which encode proteins involved in cell transformation and replication, and a late region containing two open reading frames (L1 and L2), which encode proteins of the viral capsid. In general, E6 and E7 are oncogenes that can affect cell cycle regulation and contribute to the formation of cancers. For instance, the E6 gene product can cause p53 degradation and the E7 gene product can cause retinoblastoma (Rb) inactivation.

(40) In some aspects, a provided HPV 16 binding molecule, including a TCR or antigen binding fragment thereof or an anti-HPV 16 antibody, e.g., antibody fragments thereof, and proteins such as chimeric molecules containing one or more of the foregoing, such as the chimeric receptors, e.g., TCR-like CARs, and/or engineered cells expressing the TCRs or CARs, bind to a peptide epitope derived from HPV16 E6 protein. In some aspects, a provided HPV 16 binding molecule, including a TCR or antigen binding fragments thereof or anti-HPV 16 antibody, e.g., antibody fragments and proteins containing the same, such as the chimeric receptors, e.g., TCR-like CARs, and/or engineered cells expressing the TCRs or CARs, binds to a peptide epitope derived from HPV16 E7 protein.

(41) In some aspects, the binding molecule recognizes or binds HPV 16 E6 or E7 epitopes in the context of an MHC molecule, such as an MHC Class I molecule. In some aspects, the MHC Class I molecule is an HLA-A2 molecule, including any one or more subtypes thereof, e.g. HLA-A*0201, *0202, *0203, *0206, or *0207. In some cases, there can be differences in the frequency of subtypes between different populations. For example, in some embodiments, more than 95% of the HLA-A2 positive Caucasian population is HLA-A*0201, whereas in the Chinese population the frequency has been reported to be approximately 23% HLA-A*0201, 45% HLA-A*0207, 8% HLA-A*0206 and 23% HLA-A*0203. In some embodiments, the MHC molecule is HLA-A*0201.

(42) In some embodiments, the TCR or antigen-binding fragment thereof recognizes or binds to an epitope or region of HPV16 E6 or HPV 16 E7, such as a peptide epitope containing an amino acid sequence set forth in any of SEQ ID NOs: 232-239, and as shown below in Table 1.

(44) In some embodiments, the binding molecule, e.g., TCR or antigen-binding fragment thereof or antibody or antigen-binding fragment thereof, is isolated or purified or is recombinant. In some aspects, the binding molecule, e.g., TCR or antigen-binding fragment thereof or antibody or antigen-binding fragment thereof, is human. In some embodiments, the binding molecule is monoclonal. In some aspects, the binding molecule is a single chain. In other embodiments, the binding molecule contains two chains. In some embodiments, the binding molecule, e.g., TCR or antigen-binding fragment thereof or antibody or antigen-binding fragment thereof, is expressed on the surface of a cell.

(45) In some aspects, the provided binding molecules have one or more specified functional features, such as binding properties, including binding to particular epitopes, and/or particular binding affinities as described.

(46) A. T Cell Receptors (TCRs)

(47) In some embodiments, the binding molecule that recognizes or binds an epitope or region of HPV 16 is a T cell receptor (TCR) or an antigen-binding fragment thereof.

(48) In some embodiments, a T cell receptor or TCR is a molecule that contains a variable ? and ? chains (also known as TCR? and TCR?, respectively) or a variable ? and ? chains (also known as TCR? and TCR?, respectively), or antigen-binding portions thereof, and which is capable of specifically binding to a peptide bound to an MHC molecule. In some embodiments, the TCR is in the ?? form. Typically, TCRs that exist in ?? and ?? forms are generally structurally similar, but T cells expressing them may have distinct anatomical locations or functions. A TCR can be found on the surface of a cell or in soluble form. Generally, a TCR is found on the surface of T cells (or T lymphocytes) where it is generally responsible for recognizing antigens bound to major histocompatibility complex (MHC) molecules.

(49) Unless otherwise stated, the term TCR should be understood to encompass full TCRs as well as antigen-binding portions or antigen-binding fragments thereof. In some embodiments, the TCR is an intact or full-length TCR, such as a TCR containing the ? chain and ? chain. In some embodiments, the TCR is an antigen-binding portion that is less than a full-length TCR but that binds to a specific peptide bound in an MHC molecule, such as binds to an MHC-peptide complex. In some cases, an antigen-binding portion or fragment of a TCR can contain only a portion of the structural domains of a full-length or intact TCR, but yet is able to bind the peptide epitope, such as MHC-peptide complex, to which the full TCR binds. In some cases, an antigen-binding portion contains the variable domains of a TCR, such as variable ? (V.sub.?) chain and variable ? (V.sub.?) chain of a TCR, or antigen-binding fragments thereof sufficient to form a binding site for binding to a specific MHC-peptide complex.

(50) In some embodiments, the variable domains of the TCR contain complementarity determining regions (CDRs), which generally are the primary contributors to antigen recognition and binding capabilities and specificity of the peptide, MHC and/or MHC-peptide complex. In some embodiments, a CDR of a TCR or combination thereof forms all or substantially all of the antigen-binding site of a given TCR molecule. The various CDRs within a variable region of a TCR chain generally are separated by framework regions (FRs), which generally display less variability among TCR molecules as compared to the CDRs (see, e.g., Jores et al., Proc. Nat'l Acad. Sci. U.S.A. 87:9138, 1990; Chothia et al., EMBO J. 7:3745, 1988; see also Lefranc et al., Dev. Comp. Immunol. 27:55, 2003). In some embodiments, CDR3 is the main CDR responsible for antigen binding or specificity, or is the most important among the three CDRs on a given TCR variable region for antigen recognition, and/or for interaction with the processed peptide portion of the peptide-MHC complex. In some contexts, the CDR1 of the alpha chain can interact with the N-terminal part of certain antigenic peptides. In some contexts, CDR1 of the beta chain can interact with the C-terminal part of the peptide. In some contexts, CDR2 contributes most strongly to or is the primary CDR responsible for the interaction with or recognition of the MHC portion of the MHC-peptide complex. In some embodiments, the variable region of the ?-chain can contain a further hypervariable region (CDR4 or HVR4), which generally is involved in superantigen binding and not antigen recognition (Kotb (1995) Clinical Microbiology Reviews, 8:411-426).

(51) In some embodiments, the ?-chain and/or ?-chain of a TCR also can contain a constant domain, a transmembrane domain and/or a short cytoplasmic tail (see, e.g., Janeway et al., Immunobiology: The Immune System in Health and Disease, 3.sup.rd Ed., Current Biology Publications, p. 4:33, 1997). In some aspects, each chain (e.g. alpha or beta) of the TCR can possess one N-terminal immunoglobulin variable domain, one immunoglobulin constant domain, a transmembrane region, and a short cytoplasmic tail at the C-terminal end. In some embodiments, a TCR, for example via the cytoplasmic tail, is associated with invariant proteins of the CD3 complex involved in mediating signal transduction. In some cases, the structure allows the TCR to associate with other molecules like CD3 and subunits thereof. For example, a TCR containing constant domains with a transmembrane region may anchor the protein in the cell membrane and associate with invariant subunits of the CD3 signaling apparatus or complex. The intracellular tails of CD3 signaling subunits (e.g. CD3?, CD3?, CD3? and CD3? chains) contain one or more immunoreceptor tyrosine-based activation motif or ITAM and generally are involved in the signaling capacity of the TCR complex.

(52) It is within the level of a skilled artisan to determine or identify the various domains or regions of a TCR. In some cases, the exact locus of a domain or region can vary depending on the particular structural or homology modeling or other features used to describe a particular domain. It is understood that reference to amino acids, including to a specific sequence set forth as a SEQ ID NO used to describe domain organization of a TCR are for illustrative purposes and are not meant to limit the scope of the embodiments provided. In some cases, the specific domain (e g variable or constant) can be several amino acids (such as one, two, three or four) longer or shorter. In some aspects, residues of a TCR are known or can be identified according to the International Immunogenetics Information System (IMGT) numbering system (see e.g. www.imgt.org; see also, Lefranc et al. (2003) Developmental and Comparative Immunology, 2&; 55-77; and The T Cell Factsbook 2nd Edition, Lefranc and LeFranc Academic Press 2001). Using this system, the CDR1 sequences within a TCR V? chains and/or V? chain correspond to the amino acids present between residue numbers 27-38, inclusive, the CDR2 sequences within a TCR V? chain and/or V? chain correspond to the amino acids present between residue numbers 56-65, inclusive, and the CDR3 sequences within a TCR V? chain and/or V? chain correspond to the amino acids present between residue numbers 105-117, inclusive.

(53) In some embodiments, the ? chain and ? chain of a TCR each further contain a constant domain. In some embodiments, the ? chain constant domain (C?) and ? chain constant domain (C?) individually are mammalian, such as is a human or murine constant domain. In some embodiments, the constant domain is adjacent to the cell membrane. For example, in some cases, the extracellular portion of the TCR formed by the two chains contains two membrane-proximal constant domains, and two membrane-distal variable domains, which variable domains each contain CDRs.

(54) In some embodiments, each of the C? and C? domains is human. In some embodiments, the C? is encoded by the TRAC gene (IMGT nomenclature) or is a variant thereof. In some embodiments, the C? has or comprises the sequence of amino acids set forth in SEQ ID NO: 213 or 220 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 213 or 220. In some embodiments, the Ca has or comprises the sequence of amino acids set forth in SEQ ID NO: 212, 215 or 217 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 212, 215 or 217. In some embodiments, the C? has or comprises the sequence of amino acids set forth in any of SEQ ID NOS: 212, 213, 215, 217, 220, or 524. In some embodiments, the C? is encoded by TRBC1 or TRBC2 genes (IMGT nomenclature) or is a variant thereof. In some embodiments, the C? has or comprises the sequence of amino acids set forth in SEQ ID NO:214, 216, 631, or 889 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 214, 216, 631, or 889. In some embodiments, the C? has or comprises the sequence of amino acids set forth in SEQ ID NO: 214, 216, 631, or 889.

(55) In some embodiments, any of the provided TCRs or antigen-binding fragments thereof can be a human/mouse chimeric TCR. In some cases, the TCR or antigen-binding fragment thereof comprises an alpha chain and/or a beta chain comprising a mouse constant region. In some embodiments, the C? is a mouse constant region that is or comprises the sequence of amino acids set forth in SEQ ID NO: 262, 317, 833, 1012, 1014, 1015, 1017 or 1018 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 262, 317, 833, 1012, 1014, 1015, 1017 or 1018. In some embodiments, the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 262, 317, 833, 1012, 1014, 1015, 1017 or 1018. In some embodiments, the C? is a mouse constant region that is or comprises the sequence of amino acids set forth in SEQ ID NO: 263, 109, 1013 or 1016 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 263, 109, 1013 or 1016.

In some embodiments, the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 262 or 1014 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 262 or 1014 and/or the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 263 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 263. In some embodiments, the C? and/or C? is or comprises any C? and/or C? described in WO 2015/184228, WO 2015/009604 and WO 2015/009606.

(56) In some embodiments, the TCR or antigen-binding fragment thereof herein comprises a variant of an alpha chain and/or a beta chain, e.g., an alpha and/or beta chain that comprises a mouse constant region. In some embodiments, the variant comprises the amino acid sequence of any of the TCRs described herein with one, two, three, or four or more amino acid substitution(s) in the constant region of the alpha or beta chain. In some embodiments, the variant comprises the amino acid sequence of any of the constant regions described herein with one, two, three, or four or more amino acid substitution(s) in the constant region. In some embodiments, the TCRs (or functional portions thereof) comprising the substituted amino acid sequence(s) advantageously provide one or more of increased recognition of HPV 16 targets, increased expression by a host cell, and increased anti-tumor activity as compared to the parent TCR comprising an unsubstituted amino acid sequence.

(57) In some embodiments, the substituted amino acid sequences of the mouse constant regions of the TCR ? and ? chains, SEQ ID NOs: 1015 and 1016, respectively, correspond with all or portions of the unsubstituted mouse constant region amino acid sequences SEQ ID NOs: 1014 and 263, respectively, with SEQ ID NO: 1015 having one, two, three, or four amino acid substitution(s) when compared to SEQ ID NO: 1014 and SEQ ID NO: 1016 having one amino acid substitution when compared to SEQ ID NO: 263. In some embodiments, a variant of a TCR comprises the amino acid sequences of (a) SEQ ID NO: 1015 (constant region of alpha chain), wherein (i) X at position 48 is Thr or Cys; (ii) X at position 112 is Ser, Gly, Ala, Val, Leu, Ile, Pro, Phe, Met, or Trp; (iii) X at position 114 is Met, Gly, Ala, Val, Leu, Ile, Pro, Phe, Met, or Trp; and (iv) X at position 115 is Gly, Ala, Val, Leu, Ile, Pro, Phe, Met, or Trp; and (b) SEQ ID NO: 1016 (constant region of beta chain), wherein X at position 56 is Ser or Cys. In some embodiments, the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 1015 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 1015 and/or the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 1016 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 1016.

(58) In some embodiments, the TCR may be a heterodimer of two chains ? and ? that are linked, such as by a disulfide bond or disulfide bonds. In some embodiments, the constant domain of the TCR may contain short connecting sequences in which a cysteine residue forms a disulfide bond, thereby linking the two chains of the TCR. In some embodiments, a TCR may have an additional cysteine residue in each of the ? and ? chains, such that the TCR contains two disulfide bonds in the constant domains. In some embodiments, each of the constant and variable domains contains disulfide bonds formed by cysteine residues.

(59) In some embodiments, the TCR can contain an introduced disulfide bond or bonds. In some embodiments, the native disulfide bonds are not present. In some embodiments, the one or more of the native cysteines (e.g. in the constant domain of the ? chain and ? chain) that form a native interchain disulfide bond are substituted to another residue, such as to a serine or alanine. In some embodiments, an introduced disulfide bond can be formed by mutating non-cysteine residues on the alpha and beta chains, such as in the constant domain of the ? chain and ? chain, to cysteine. Opposing cysteines in the TCR ? and ? chains in provide a disulfide bond that links the constant regions of TCR ? and ? chains of the substituted TCR to one another and which is not present in a TCR comprising the unsubstituted human constant region or the unsubstituted mouse constant region. In some embodiments, the presence of non-native cysteine residues (e.g. resulting in one or more non-native disulfide bonds) in a recombinant TCR can favor production of the desired recombinant TCR in a cell in which it is introduced over expression of a mismatched TCR pair containing a native TCR chain.

(60) Exemplary non-native disulfide bonds of a TCR are described in published International PCT No. WO2006/000830 and WO2006/037960. In some embodiments, cysteines can be introduced or substituted at residue Thr48 of the C? chain and Ser57 of the C? chain, at residue Thr45 of the C? chain and Ser77 of the C? chain, at residue Tyr10 of the C? chain and Ser17 of the C? chain, at residue Thr45 of the C? chain and Asp59 of the C? chain and/or at residue Ser15 of the C? chain and Glu15 of the C? chain with reference to numbering of a C? set forth in any of SEQ ID NOS: 212, 213, 217, or 524, or C? set forth in SEQ ID NO: 214 or 216. In some embodiments, the variant of the TCR is a cysteine-substituted, chimeric TCR in which one or both of the native Thr48 of SEQ ID NO: 1014 and the native Ser57 of SEQ ID NO: 263 is substituted with Cys. In some embodiments, the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 1017 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 1017 and/or the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 1016 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 1013.

(61) In some embodiments, any of the provided cysteine mutations can be made at a corresponding position in another sequence, for example, in the mouse C? and C? sequences described above. The term corresponding with reference to positions of a protein, such as recitation that amino acid positions correspond to amino acid positions in a disclosed sequence, such as set forth in the Sequence listing, refers to amino acid positions identified upon alignment with the disclosed sequence based on structural sequence alignment or using a standard alignment algorithm, such as the GAP algorithm. For example, corresponding residues can be determined by alignment of a reference sequence with the C? sequence set forth in any of SEQ ID NOS: 212, 213, 215, 217, 220, or 524, or the C? sequence set forth in SEQ ID NO: 214, 216, 631, or 889, by structural alignment methods as described herein. By aligning the sequences, one skilled in the art can identify corresponding residues, for example, using conserved and identical amino acid residues as guides.

(62) In some embodiments, the variant includes substitutions of one, two, or three amino acids in the transmembrane (TM) domain of the constant region of one or both of the ? and ? chains with a hydrophobic amino acid to provide a hydrophobic amino acid-substituted TCR. The hydrophobic amino acid substitution(s) in the TM domain of the TCR may increase the hydrophobicity of the TM domain of the TCR as compared to a TCR that lacks the hydrophobic amino acid substitution(s) in the TM domain. In some embodiments, the variant of the TCR comprises one, two, or three of the native Ser 112, Met 114, and Gly 115 of SEQ ID NO: 1014 may, independently, be substituted with Gly, Ala, Val, Leu, Ile, Pro, Phe, Met, or Trp; for example with Leu, Ile, or Val. In some embodiments, the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 1018 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 1018 and/or the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 263 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 263.

(63) In some embodiments, the variant includes cysteine substitutions in the constant region of one or both of the ? and ? chains in combination with the substitution(s) of one, two, or three amino acids in the transmembrane (TM) domain of the constant region of one or both of the ? and ? chains with a hydrophobic amino acid. In some embodiments, the variant has the native Thr48 of SEQ ID NO: 1014 substituted with Cys; one, two, or three of the native Ser 112, Met 114, and Gly 115 of SEQ ID NO: 1014, independently, substituted with Gly, Ala, Val, Leu, Ile, Pro, Phe, Met, or Trp; for example with Leu, Ile, or Val; and the native Ser56 of SEQ ID NO: 19 substituted with Cys. In some embodiments, the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 833 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 833 and/or the C? is or comprises the sequence of amino acids set forth in SEQ ID NO: 1013 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 1013.

(64) Exemplary sequences (e.g. CDRs, V.sub.? and/or V.sub.? and constant region sequences) of provided TCRs are described below.

(65) In some embodiments, the TCR is a full-length TCR. In some embodiments, the TCR is an antigen-binding portion. In some embodiments, the TCR is a dimeric TCR (dTCR). In some embodiments, the TCR is a single-chain TCR (sc-TCR). A TCR may be cell-bound or in soluble form. In some embodiments, the TCR is in cell-bound form expressed on the surface of a cell.

(66) In some embodiments a dTCR contains a first polypeptide wherein a sequence corresponding to a provided TCR ? chain variable region sequence is fused to the N terminus of a sequence corresponding to a TCR ? chain constant region extracellular sequence, and a second polypeptide wherein a sequence corresponding to a provided TCR ? chain variable region sequence is fused to the N terminus a sequence corresponding to a TCR ? chain constant region extracellular sequence, the first and second polypeptides being linked by a disulfide bond. In some embodiments, the bond can correspond to the native interchain disulfide bond present in native dimeric ?? TCRs. In some embodiments, the interchain disulfide bonds are not present in a native TCR. For example, in some embodiments, one or more cysteines can be incorporated into the constant region extracellular sequences of dTCR polypeptide pair. In some cases, both a native and a non-native disulfide bond may be desirable. In some embodiments, the TCR contains a transmembrane sequence to anchor to the membrane.

(67) In some embodiments, a dTCR contains a provided TCR ? chain containing a variable a domain, a constant ? domain and a first dimerization motif attached to the C-terminus of the constant ? domain, and a provided TCR ? chain comprising a variable ? domain, a constant ? domain and a first dimerization motif attached to the C-terminus of the constant ? domain, wherein the first and second dimerization motifs easily interact to form a covalent bond between an amino acid in the first dimerization motif and an amino acid in the second dimerization motif linking the TCR ? chain and TCR ? chain together.

(68) In some embodiments, the TCR is a scTCR, which is a single amino acid strand containing an ? chain and a ? chain that is able to bind to MHC-peptide complexes. Typically, a scTCR can be generated using methods known to those of skill in the art, See e.g., International published PCT Nos. WO 96/13593, WO 96/18105, WO99/18129, WO 04/033685, WO2006/037960, WO2011/044186; U.S. Pat. No. 7,569,664; and Schlueter, C. J. et al. J. Mol. Biol. 256, 859 (1996).

(69) In some embodiments, a scTCR contains a first segment constituted by an amino acid sequence corresponding to a sequence of a provided TCR ? chain variable region, a second segment constituted by an amino acid sequence corresponding to a provided TCR ? chain variable region sequence fused to the N terminus of an amino acid sequence corresponding to a TCR ? chain constant domain extracellular sequence, and a linker sequence linking the C terminus of the first segment to the N terminus of the second segment.

(70) In some embodiments, a scTCR contains a first segment constituted by an amino acid sequence corresponding to a provided TCR ? chain variable region, a second segment constituted by an amino acid sequence corresponding to a provided TCR ? chain variable region sequence fused to the N terminus of an amino acid sequence corresponding to a TCR ? chain constant domain extracellular sequence, and a linker sequence linking the C terminus of the first segment to the N terminus of the second segment.

(71) In some embodiments, a scTCR contains a first segment constituted by a provided ? chain variable region sequence fused to the N terminus of an ? chain extracellular constant domain sequence, and a second segment constituted by a provided ? chain variable region sequence fused to the N terminus of a sequence ? chain extracellular constant and transmembrane sequence, and, optionally, a linker sequence linking the C terminus of the first segment to the N terminus of the second segment.

(72) In some embodiments, a scTCR contains a first segment constituted by a provided TCR ? chain variable region sequence fused to the N terminus of a ? chain extracellular constant domain sequence, and a second segment constituted by a provided ? chain variable region sequence fused to the N terminus of a sequence ? chain extracellular constant and transmembrane sequence, and, optionally, a linker sequence linking the C terminus of the first segment to the N terminus of the second segment.

(73) In some embodiments, for the scTCR to bind an MHC-peptide complex, the ? and ? chains must be paired so that the variable region sequences thereof are orientated for such binding. Various methods of promoting pairing of an ? and ? in a scTCR are well known in the art. In some embodiments, a linker sequence is included that links the ? and ? chains to form the single polypeptide strand. In some embodiments, the linker should have sufficient length to span the distance between the C terminus of the ? chain and the N terminus of the ? chain, or vice versa, while also ensuring that the linker length is not so long so that it blocks or reduces bonding of the scTCR to the target peptide-MHC complex.

(74) In some embodiments, the linker of a scTCRs that links the first and second TCR segments can be any linker capable of forming a single polypeptide strand, while retaining TCR binding specificity. In some embodiments, the linker sequence may, for example, have the formula -P-AA-P-, wherein P is proline and AA represents an amino acid sequence wherein the amino acids are glycine and serine. In some embodiments, the first and second segments are paired so that the variable region sequences thereof are orientated for such binding. Hence, in some cases, the linker has a sufficient length to span the distance between the C terminus of the first segment and the N terminus of the second segment, or vice versa, but is not too long to block or reduces bonding of the scTCR to the target ligand. In some embodiments, the linker can contain from or from about 10 to 45 amino acids, such as 10 to 30 amino acids or 26 to 41 amino acids residues, for example 29, 30, 31 or 32 amino acids. In some embodiments, the linker has the formula -PGGG-(SGGGG).sub.n-P-, wherein n is 5 or 6 and P is proline, G is glycine and S is serine (SEQ ID NO: 266). In some embodiments, the linker has the sequence GSADDAKKDAAKKDGKS (SEQ ID NO: 267).

(75) In some embodiments, a scTCR contains a disulfide bond between residues of the single amino acid strand, which, in some cases, can promote stability of the pairing between the ? and ? regions of the single chain molecule (see e.g. U.S. Pat. No. 7,569,664). In some embodiments, the scTCR contains a covalent disulfide bond linking a residue of the immunoglobulin region of the constant domain of the ? chain to a residue of the immunoglobulin region of the constant domain of the ? chain of the single chain molecule. In some embodiments, the disulfide bond corresponds to the native disulfide bond present in a native dTCR. In some embodiments, the disulfide bond in a native TCR is not present. In some embodiments, the disulfide bond is an introduced non-native disulfide bond, for example, by incorporating one or more cysteines into the constant region extracellular sequences of the first and second chain regions of the scTCR polypeptide. Exemplary cysteine mutations include any as described above. In some cases, both a native and a non-native disulfide bond may be present.

(76) In some embodiments, a scTCR is a non-disulfide linked truncated TCR in which heterologous leucine zippers fused to the C-termini thereof facilitate chain association (see e.g. International published PCT No. WO99/60120). In some embodiments, a scTCR contain a TCR? variable domain covalently linked to a TCR? variable domain via a peptide linker (see e.g., International published PCT No. WO99/18129).

(77) In some embodiments, any of the provided TCRs, including a dTCR or scTCR, can be linked to signaling domains that yield an active TCR on the surface of a T cell. In some embodiments, the TCR is expressed on the surface of cells. In some embodiments, the TCR does contain a sequence corresponding to a transmembrane sequence. In some embodiments, the transmembrane domain is positively charged. In some embodiments, the transmembrane domain can be a C? or C? transmembrane domain. In some embodiments, the transmembrane domain can be from a non-TCR origin, for example, a transmembrane region from CD3z, CD28 or B7.1. In some embodiments, the TCR does contain a sequence corresponding to cytoplasmic sequences. In some embodiments, the TCR contains a CD3z signaling domain. In some embodiments, the TCR is capable of forming a TCR complex with CD3.

(78) In some embodiments, the TCR is a soluble TCR. In some embodiments, the soluble TCR has a structure as described in WO99/60120 or WO 03/020763. In some embodiments, the TCR does not contain a sequence corresponding to the transmembrane sequence, for example, to permit membrane anchoring into the cell in which it is expressed. In some embodiments, the TCR does not contain a sequence corresponding to cytoplasmic sequences.

(248) 2. Variants & Modifications

(249) In some embodiments, the binding molecule, e.g., TCR or antigen-binding fragment thereof, is or has been modified. In certain embodiments, the binding molecules, e.g., TCRs or antigen-binding fragments thereof, include one or more amino acid variations, e.g., substitutions, deletions, insertions, and/or mutations, compared to the sequence of a binding molecule, e.g., TCR, described herein. Exemplary variants include those designed to improve the binding affinity and/or other biological properties of the binding molecule Amino acid sequence variants of a binding molecule may be prepared by introducing appropriate modifications into the nucleotide sequence encoding the binding molecule, or by peptide synthesis. Such modifications include, for example, deletions from, and/or insertions into and/or substitutions of residues within the amino acid sequences of the binding molecule. Any combination of deletion, insertion, and substitution can be made to arrive at the final construct, provided that the final construct possesses the desired characteristics, e.g., antigen-binding.

(250) In some embodiments, directed evolution methods are used to generate TCRs with altered properties, such as with higher affinity for a specific peptide in the context of an MHC molecule. In some embodiments, directed evolution is achieved by display methods including, but not limited to, yeast display (Holler et al. (2003) Nat Immunol, 4, 55-62; Holler et al. (2000) Proc Natl Acad Sci USA, 97, 5387-92), phage display (Li et al. (2005) Nat Biotechnol, 23, 349-54), or T cell display (Chervin et al. (2008) J Immunol Methods, 339, 175-84). In some embodiments, display approaches involve engineering, or modifying, a known, parent or reference TCR. For example, in some cases, a reference TCR, such as any provided herein, can be used as a template for producing mutagenized TCRs in which in one or more residues of the CDRs are mutated, and mutants with a desired altered property, such as higher affinity for peptide epitope in the context of an MHC molecule, are selected.

(251) In certain embodiments, the binding molecules, e.g., TCRs or antigen-binding fragments thereof, include one or more amino acid substitutions, e.g., as compared to a binding molecule, e.g., TCR, sequence described herein and/or compared to a sequence of a natural repertoire, e.g., human repertoire. Sites of interest for substitutional mutagenesis include the CDRs, FRs and/or constant regions Amino acid substitutions may be introduced into a binding molecule of interest and the products screened for a desired activity, e.g., retained/improved antigen affinity or avidity, decreased immunogenicity, improved half-life, CD8-independent binding or activity, surface expression, promotion of TCR chain pairing and/or other improved properties or functions.

(252) In some embodiments, one or more residues within a CDR of a parent binding molecule, e.g., TCR, is/are substituted. In some embodiments, the substitution is made to revert a sequence or position in the sequence to a germline sequence, such as a binding molecule sequence found in the germline (e.g., human germline), for example, to reduce the likelihood of immunogenicity, e.g., upon administration to a human subject.

(253) In certain embodiments, substitutions, insertions, or deletions may occur within one or more CDRs so long as such alterations do not substantially reduce the ability of the binding molecule, e.g., TCR or antigen-binding fragment thereof, to bind antigen. For example, conservative alterations (e.g., conservative substitutions as provided herein) that do not substantially reduce binding affinity may be made in CDRs. Such alterations may, for example, be outside of antigen contacting residues in the CDRs. In certain embodiments of the variable sequences provided herein, each CDR either is unaltered, or contains no more than one, two or three amino acid substitutions.

(254) Amino acid sequence insertions include amino- and/or carboxyl-terminal fusions ranging in length from one residue to polypeptides containing a hundred or more residues, as well as intrasequence insertions of single or multiple amino acid residues.

(255) In some aspects, the TCR or antigen-binding fragment thereof may contain one or more modifications in the alpha chain and/or beta chain such that when the TCR or antigen-binding fragment thereof is expressed in a cell, the frequency of mis-pairing between the TCR alpha chain and beta chain and an endogenous TCR alpha chain and beta chain is reduced, the expression of the TCR alpha chain and beta chain is increased, and/or the stability of the TCR alpha chain and beta chain is increased.

(256) In some embodiments, the TCR contains one or more non-native cysteine residues to introduce a covalent disulfide bond linking a residue of the immunoglobulin region of the constant domain of the ? chain to a residue of the immunoglobulin region of the constant domain of the ? chain. In some embodiments, one or more cysteines can be incorporated into the constant region extracellular sequences of the first and second segments of the TCR polypeptide. Exemplary non-limiting modifications in a TCR to introduce a non-native cysteine residues are described herein (see also, International PCT No. WO2006/000830 and WO2006037960). In some cases, both a native and a non-native disulfide bond may be desirable. In some embodiments, the TCR or antigen-binding fragment is modified such that the interchain disulfide bond in a native TCR is not present.

(257) In some embodiments, the transmembrane domain of the constant region of the TCR can be modified to contain a greater number of hydrophobic residues (see e.g. Haga-Friedman et al. (2012) Journal of Immunology, 188:5538-5546). In some embodiments, the transmembrane region of TCR ? chain contains one or more mutations corresponding to S116L, G119V or F120L, with reference to numbering of a C? set forth in any of SEQ ID NOS: 212, 213, 215, 217, 220, or 524.

(258) In some embodiments, the cell expressing the TCR further includes a marker, such as a cell surface marker, which may be used to confirm transduction or engineering of the cell to express the TCR, such as a truncated version of a cell surface receptor, such as truncated EGFR (tEGFR). Exemplary surrogate markers can include truncated forms of cell surface polypeptides, such as truncated forms that are non-functional and to not transduce or are not capable of transducing a signal or a signal ordinarily transduced by the full-length form of the cell surface polypeptide, and/or do not or are not capable of internalizing Exemplary truncated cell surface polypeptides including truncated forms of growth factors or other receptors such as a truncated human epidermal growth factor receptor 2 (tHER2), a truncated epidermal growth factor receptor (tEGFR, exemplary tEGFR sequence set forth in SEQ ID NO: 273 or 343) or a prostate-specific membrane antigen (PSMA) or modified form thereof. tEGFR may contain an epitope recognized by the antibody cetuximab (Erbitux?) or other therapeutic anti-EGFR antibody or binding molecule, which can be used to identify or select cells that have been engineered with the tEGFR construct and an encoded exogenous protein, and/or to eliminate or separate cells expressing the encoded exogenous protein. See U.S. Pat. No. 8,802,374 and Liu et al., Nature Biotech. 2016 April; 34(4): 430-434). In some aspects, the marker, e.g. surrogate marker, includes all or part (e.g., truncated form) of CD34, a NGFR, a CD19 or a truncated CD19, e.g., a truncated non-human CD19, or epidermal growth factor receptor (e.g., tEGFR). In some embodiments, the marker is or comprises a fluorescent protein, such as green fluorescent protein (GFP), enhanced green fluorescent protein (EGFP), such as super-fold GFP (sfGFP), red fluorescent protein (RFP), such as tdTomato, mCherry, mStrawberry, AsRed2, DsRed or DsRed2, cyan fluorescent protein (CFP), blue green fluorescent protein (BFP), enhanced blue fluorescent protein (EBFP), and yellow fluorescent protein (YFP), and variants thereof, including species variants, monomeric variants, and codon-optimized and/or enhanced variants of the fluorescent proteins. In some embodiments, the marker is or comprises an enzyme, such as a luciferase, the lacZ gene from E. coli, alkaline phosphatase, secreted embryonic alkaline phosphatase (SEAP), chloramphenicol acetyl transferase (CAT). Exemplary light-emitting reporter genes include luciferase (luc), ?-galactosidase, chloramphenicol acetyltransferase (CAT), ?-glucuronidase (GUS) or variants thereof.

(259) In some embodiments, the marker is a selection marker. In some embodiments, the selection marker is or comprises a polypeptide that confers resistance to exogenous agents or drugs. In some embodiments, the selection marker is an antibiotic resistance gene. In some embodiments, the selection marker is an antibiotic resistance gene confers antibiotic resistance to a mammalian cell. In some embodiments, the selection marker is or comprises a Puromycin resistance gene, a Hygromycin resistance gene, a Blasticidin resistance gene, a Neomycin resistance gene, a Geneticin resistance gene or a Zeocin resistance gene or a modified form thereof.

(260) In some aspects, the marker includes all or part (e.g., truncated form) of CD34, a NGFR, or epidermal growth factor receptor (e.g., tEGFR). In some embodiments, the nucleic acid encoding the marker is operably linked to a polynucleotide encoding for a linker sequence, such as a cleavable linker sequence, e.g., T2A. See WO2014031687. In some embodiments, introduction of a construct encoding the TCR and EGFRt separated by a T2A, P2A or other ribosome switch can express two proteins from the same construct, such that the EGFRt can be used as a marker to detect cells expressing such construct. Exemplary of such markers that can be used are described below.

(261) In some embodiments, the TCR or antigen-binding fragment thereof is encoded by a nucleotide sequence that is or has been codon-optimized. Exemplary codon-optimized variants are described elsewhere herein.

In some aspects, the antibody or antigen-binding fragment contains a variable region that contains a complementarity determining region 1 (CDR-1), a CDR-2, and a CDR-3, respectively comprising the CDR-1, CDR-2, and CDR-3 amino acid sequences contained within a V? region amino acid sequence set forth in any of SEQ ID NOs: 112, 114, 116, 122, 124 126, 298, 300, 483, 498, 516, 530, 545, 560, 578, 593, 605, 617, 629, 643, 655, 667, or 685. Also among the provided antibodies or antigen-bind fragments are those containing sequences at least at or about 90, 91, 92, 93, 94, 95, 96, 97, 98, or 99% identical to such sequences.

(266) In some embodiments, the provided antibody or antibody fragment is a human antibody. In some embodiments, the provided antibody or antibody fragment contains a V.sub.H region that contains a portion having at least 95%, 96%, 97%, 98%, 99%, or 100% sequence identity to an amino acid sequence encoded by a germline nucleotide human heavy chain V segment, a portion with at least 95%, 96%, 97%, 98%, 99%, or 100% identity to an amino acid sequence encoded by a germline nucleotide human heavy chain D segment, and/or a portion having at least 95%, 96%, 97%, 98%, 99%, or 100% identity to an amino acid sequence encoded by a germline nucleotide human heavy chain J segment; and/or contains a V.sub.L region that contains a portion with at least 95%, 96%, 97%, 98%, 99%, or 100% identity to an amino acid sequence encoded by a germline nucleotide human kappa or lambda chain V segment, and/or a portion with at least 95%, 96%, 97%, 98%, 99%, or 100% identity to an amino acid sequence encoded by a germline nucleotide human kappa or lambda chain J segment. In some embodiments, the portion of the V.sub.H region corresponds to the CDR-H1, CDR-H2 and/or CDR-H3. In some embodiments, the portion of the V.sub.H region corresponds to the framework region 1 (FR1), FR2, FR2 and/or FR4. In some embodiments, the portion of the V.sub.L region corresponds to the CDR-L1, CDR-L2 and/or CDR-L3. In some embodiments, the portion of the V.sub.L region corresponds to the FR1, FR2, FR2 and/or FR4.

(267) In some embodiments, the antibody or antigen-binding fragment contains a framework region that contains human germline gene segment sequences. For example, in some embodiments, the antibody or antigen-binding fragment contains a V.sub.H region in which the framework region, e.g. FR1, FR2, FR3 and FR4, has at least 95%, 96%, 97%, 98%, 99%, or 100% sequence identity to a framework region encoded by a human germline antibody segment, such as a V and/or J segment. In some embodiments, the human antibody contains a V.sub.L region in which the framework region e.g. FR1, FR2, FR3 and FR4, has at least 95%, 96%, 97%, 98%, 99%, or 100% sequence identity to a framework region encoded by a human germline antibody segment, such as a V and/or segment. For example, in some such embodiments, the framework sequence of the V.sub.H and/or V.sub.L sequence differs by no more than 10 amino acids, such as no more than 9, 8, 7, 6, 5, 4, 3, 2 or 1 amino acid, compared to the framework region encoded by a human germline antibody segment. In some embodiments, the antibodies and antigen binding fragments thereof, e.g. TCR-like antibodies, specifically recognize a peptide epitope in the context of an MHC molecule, such as an MHC class I. In some cases, the MHC class I molecule is an HLA-A2 molecule, e.g. HLA-A2*01.

(268) In some embodiments, the antibody or antigen-binding fragment thereof recognizes or binds to an epitope or region of HPV16 E6, such as a peptide epitope containing an amino acid sequence set forth in any of SEQ ID NOs: 232-234. In some instances, the TCR or antigen-binding fragment thereof that recognizes or binds a peptide epitope derived from HPV16 E6 is or comprises the sequence set forth in SEQ ID NO: 233.

(269) In some aspects, the TCR or antigen-binding fragment recognizes or binds to an epitope or region of HPV16 E7 protein, such as a peptide epitope containing an amino acid sequence set forth in any of SEQ ID NOs: 235-239. In some embodiments, the TCR or antigen-binding fragment thereof does not recognize or bind the epitope E7 (11-19) comprising the amino acid sequence YMLDLQPET (SEQ ID NO. 236). In some cases, the peptide derived from HPV16 E7 is or contains the sequence set forth in SEQ ID NO: 235.

(270) Thus, provided in some embodiments are anti-HPV antibodies, including functional antibody fragments. In some embodiments, the antibodies V.sub.H and/or V.sub.L domains, or antigen-binding site thereof, and are capable of specifically binding to a peptide epitope of HPV 16. In some embodiments, the antibodies include a variable heavy chain and a variable light chain, such as scFvs. The antibodies include antibodies that specifically bind to HPV, e.g., HPV 16 E6 or HPV 16 E7. Among the provided anti-HPV antibodies are human antibodies. The antibodies include isolated antibodies. Also provided are molecules containing such antibodies, e.g., single-chain proteins, fusion proteins, and/or recombinant receptors such as chimeric receptors, including antigen receptors.

(271) The term antibody herein is used in the broadest sense and includes polyclonal and monoclonal antibodies, including intact antibodies and functional (antigen-binding) antibody fragments, including fragment antigen binding (Fab) fragments, F(ab).sub.2 fragments, Fab fragments, Fv fragments, recombinant IgG (rIgG) fragments, variable heavy chain (V.sub.H) regions capable of specifically binding the antigen, single chain antibody fragments, including single chain variable fragments (scFv), and single domain antibodies (e.g., sdAb, sdFv, nanobody) fragments. The term encompasses genetically engineered and/or otherwise modified forms of immunoglobulins, such as intrabodies, peptibodies, chimeric antibodies, fully human antibodies, humanized antibodies, and heteroconjugate antibodies, multispecific, e.g., bispecific, antibodies, diabodies, triabodies, and tetrabodies, tandem di-scFv, tandem tri-scFv. Unless otherwise stated, the term antibody should be understood to encompass functional antibody fragments thereof. The term also encompasses intact or full-length antibodies, including antibodies of any class or sub-class, including IgG and sub-classes thereof, IgM, IgE, IgA, and IgD.

(272) In some embodiments, the heavy and light chains of an antibody can be full-length or can be an antigen-binding portion (a Fab, F(ab)2, Fv or a single chain Fv fragment (scFv)). In other embodiments, the antibody heavy chain constant region is chosen from, e.g., IgG1, IgG2, IgG3, IgG4, IgM, IgA1, IgA2, IgD, and IgE, particularly chosen from, e.g., IgG1, IgG2, IgG3, and IgG4, more particularly, IgG1 (e.g., human IgG1). In another embodiment, the antibody light chain constant region is chosen from, e.g., kappa or lambda, particularly kappa.

(273) Among the provided antibodies are antibody fragments. An antibody fragment refers to a molecule other than an intact antibody that comprises a portion of an intact antibody that binds the antigen to which the intact antibody binds. Examples of antibody fragments include but are not limited to Fv, Fab, Fab, Fab-SH, F(ab)2; diabodies; linear antibodies; variable heavy chain (V.sub.H) regions, single-chain antibody molecules such as scFvs and single-domain V.sub.H single antibodies; and multispecific antibodies formed from antibody fragments. In particular embodiments, the antibodies are single-chain antibody fragments comprising a variable heavy chain region and/or a variable light chain region, such as scFvs.

(274) The term variable region or variable domain, when used in reference to an antibody, such as an antibody fragment, refers to the domain of an antibody heavy or light chain that is involved in binding the antibody to antigen. The variable domains of the heavy chain and light chain (V.sub.H and V.sub.L, respectively) of a native antibody generally have similar structures, with each domain comprising four conserved framework regions (FRs) and three CDRs. (See, e.g., Kindt et al. Kuby Immunology, 6th ed., W.H. Freeman and Co., page 91 (2007). A single V.sub.H or V.sub.L domain may be sufficient to confer antigen-binding specificity. Furthermore, antibodies that bind a particular antigen may be isolated using a V.sub.H or V.sub.L domain from an antibody that binds the antigen to screen a library of complementary V.sub.L or V.sub.H domains, respectively. See, e.g., Portolano et al., J. Immunol. 150:880-887 (1993); Clarkson et al., Nature 352:624-628 (1991).

(275) Single-domain antibodies are antibody fragments comprising all or a portion of the heavy chain variable domain or all or a portion of the light chain variable domain of an antibody. In certain embodiments, a single-domain antibody is a human single-domain antibody.

(276) Antibody fragments can be made by various techniques, including but not limited to proteolytic digestion of an intact antibody as well as production by recombinant host cells. In some embodiments, the antibodies are recombinantly-produced fragments, such as fragments comprising arrangements that do not occur naturally, such as those with two or more antibody regions or chains joined by synthetic linkers, e.g., peptide linkers, and/or that are may not be produced by enzyme digestion of a naturally-occurring intact antibody. In some aspects, the antibody fragments are scFvs.

(277) Among the provided anti-HPV antibodies are human antibodies. A human antibody is an antibody with an amino acid sequence corresponding to that of an antibody produced by a human or a human cell, or non-human source that utilizes human antibody repertoires or other human antibody-encoding sequences, including human antibody libraries. The term excludes humanized forms of non-human antibodies comprising non-human antigen-binding regions, such as those in which all or substantially all CDRs are non-human. The term includes antigen-binding fragments of human antibodies.

(278) A humanized antibody is an antibody in which all or substantially all CDR amino acid residues are derived from non-human CDRs and all or substantially all FR amino acid residues are derived from human FRs. A humanized antibody optionally may include at least a portion of an antibody constant region derived from a human antibody. A humanized form of a non-human antibody, refers to a variant of the non-human antibody that has undergone humanization, typically to reduce immunogenicity to humans, while retaining the specificity and affinity of the parental non-human antibody. In some embodiments, some FR residues in a humanized antibody are substituted with corresponding residues from a non-human antibody (e.g., the antibody from which the CDR residues are derived), e.g., to restore or improve antibody specificity or affinity.

(279) Human antibodies may be prepared by administering an immunogen to a transgenic animal that has been modified to produce intact human antibodies or intact antibodies with human variable regions in response to antigenic challenge. Such animals typically contain all or a portion of the human immunoglobulin loci, which replace the endogenous immunoglobulin loci, or which are present extrachromosomally or integrated randomly into the animal's chromosomes. In such transgenic animals, the endogenous immunoglobulin loci have generally been inactivated. Human antibodies also may be derived from human antibody libraries, including phage display and cell-free libraries, containing antibody-encoding sequences derived from a human repertoire.

(280) Among the provided antibodies are monoclonal antibodies, including monoclonal antibody fragments. The term monoclonal antibody as used herein refers to an antibody obtained from or within a population of substantially homogeneous antibodies, i.e., the individual antibodies comprising the population are identical, except for possible variants containing naturally occurring mutations or arising during production of a monoclonal antibody preparation, such variants generally being present in minor amounts. In contrast to polyclonal antibody preparations, which typically include different antibodies directed against different epitopes, each monoclonal antibody of a monoclonal antibody preparation is directed against a single epitope on an antigen. The term is not to be construed as requiring production of the antibody by any particular method. A monoclonal antibody may be made by a variety of techniques, including but not limited to generation from a hybridoma, recombinant DNA methods, phage-display and other antibody display methods.

(281) As used herein, reference to a corresponding form of an antibody means that when comparing a property or activity of two antibodies, the property is compared using the same form of the antibody. For example, if it is stated that an antibody has greater activity compared to the activity of the corresponding form of a first antibody, that means that a particular form, such as a scFv of that antibody, has greater activity compared to the scFv form of the first antibody.

(282) Effector functions refer to those biological activities attributable to the Fc region of an antibody, which vary with the antibody isotype. Examples of antibody effector functions include: C1q binding and complement dependent cytotoxicity (CDC); Fc receptor binding; antibody-dependent cell-mediated cytotoxicity (ADCC); phagocytosis; down regulation of cell surface receptors (e.g. B cell receptor); and B cell activation.

(283) In some embodiments, the antibody, e.g., antibody fragment, may contain at least a portion of an immunoglobulin constant region, such as one or more constant region domain. In some embodiments, the constant regions include a light chain constant region and/or a heavy chain constant region 1 (CH1). In some embodiments, the antibody includes a CH2 and/or CH3 domain, such as an Fc region. In some embodiments, the Fc region is an Fc region of a human IgG, such as an IgG1 or IgG4.

(284) The term Fc region herein is used to define a C-terminal region of an immunoglobulin heavy chain that contains at least a portion of the constant region. The term includes native sequence Fc regions and variant Fc regions. In one embodiment, a human IgG heavy chain Fc region extends from Cys226, or from Pro230, to the carboxyl-terminus of the heavy chain. However, the C-terminal lysine (Lys447) of the Fc region may or may not be present. Unless otherwise specified herein, numbering of amino acid residues in the Fc region or constant region is according to the EU numbering system, also called the EU index, as described in Kabat et al., Sequences of Proteins of Immunological Interest, 5th Ed. Public Health Service, National Institutes of Health, Bethesda, Md., 1991.

(285) The terms full length antibody, intact antibody, and whole antibody are used herein interchangeably to refer to an antibody having a structure substantially similar to a native antibody structure or having heavy chains that contain an Fc region as defined herein.

(286) An isolated antibody is one which has been separated from a component of its natural environment. In some embodiments, an antibody is purified to greater than 95% or 99% purity as determined by, for example, electrophoretic (e.g., SDS-PAGE, isoelectric focusing (IEF), capillary electrophoresis) or chromatographic (e.g., ion exchange or reverse phase HPLC). For review of methods for assessment of antibody purity, see, e.g., Flatman et al., J. Chromatogr. B 848:79-87 (2007).

(287) 1. Variants and Modifications

(288) In certain embodiments, the antibodies or antigen-binding fragments thereof include one or more amino acid variations, e.g., substitutions, deletions, insertions, and/or mutations, compared to the sequence of an antibody described herein. Exemplary variants include those designed to improve the binding affinity and/or other biological properties of the antibody. Amino acid sequence variants of an antibody may be prepared by introducing appropriate modifications into the nucleotide sequence encoding the antibody, or by peptide synthesis. Such modifications include, for example, deletions from, and/or insertions into and/or substitutions of residues within the amino acid sequences of the antibody. Any combination of deletion, insertion, and substitution can be made to arrive at the final construct, provided that the final construct possesses the desired characteristics, e.g., antigen-binding.

(289) In certain embodiments, the antibodies include one or more amino acid substitutions, e.g., as compared to an antibody sequence described herein and/or compared to a sequence of a natural repertoire, e.g., human repertoire. Sites of interest for substitutional mutagenesis include the CDRs and FRs Amino acid substitutions may be introduced into an antibody of interest and the products screened for a desired activity, e.g., retained/improved antigen binding, decreased immunogenicity, improved half-life, and/or improved effector function, such as the ability to promote antibody-dependent cellular cytotoxicity (ADCC) or complement-dependent cytotoxicity (CDC).

(290) In some embodiments, one or more residues within a CDR of a parent antibody (e.g. a humanized or human antibody) is/are substituted. In some embodiments, the substitution is made to revert a sequence or position in the sequence to a germline sequence, such as an antibody sequence found in the germline (e.g., human germline), for example, to reduce the likelihood of immunogenicity, e.g., upon administration to a human subject.

(291) In some embodiments, alterations are made in CDR hotspots, residues encoded by codons that undergo mutation at high frequency during the somatic maturation process (see, e.g., Chowdhury, Methods Mol. Biol. 207:179-196 (2008)), and/or residues that contact antigen, with the resulting variant V.sub.H or V.sub.L being tested for binding affinity. Affinity maturation by constructing and reselecting from secondary libraries has been described, e.g., in Hoogenboom et al. in Methods in Molecular Biology 178:1-37 (O'Brien et al., ed., Human Press, Totowa, N.J., (2001)). In some embodiments of affinity maturation, diversity is introduced into the variable genes chosen for maturation by any of a variety of methods (e.g., error-prone PCR, chain shuffling, or oligonucleotide-directed mutagenesis). A secondary library may then be created and screened to identify any antibody variants with the desired affinity. Another method to introduce diversity involves CDR-directed approaches, in which several CDR residues (e.g., 4-6 residues at a time) are randomized. CDR residues involved in antigen binding may be specifically identified, e.g., using alanine scanning mutagenesis or modeling. CDR-H3 and CDR-L3 in particular are often targeted.

(292) In certain embodiments, substitutions, insertions, or deletions may occur within one or more CDRs so long as such alterations do not substantially reduce the ability of the antibody to bind antigen. For example, conservative alterations (e.g., conservative substitutions as provided herein) that do not substantially reduce binding affinity may be made in CDRs. Such alterations may, for example, be outside of antigen contacting residues in the CDRs. In certain embodiments of the variant V.sub.H and V.sub.L sequences provided above, each CDR either is unaltered, or contains no more than one, two or three amino acid substitutions.

(293) Amino acid sequence insertions include amino- and/or carboxyl-terminal fusions ranging in length from one residue to polypeptides containing a hundred or more residues, as well as intrasequence insertions of single or multiple amino acid residues. Examples of terminal insertions include an antibody with an N-terminal methionyl residue. Other insertional variants of the antibody molecule include the fusion to the N- or C-terminus of the antibody to an enzyme or a polypeptide which increases the serum half-life of the antibody.

(294) In certain embodiments, the antibody or antigen-binding fragment thereof is altered to increase or decrease the extent to which the antibody is glycosylated, for example, by removing or inserting one or more glycosylation sites by altering the amino acid sequence and/or by modifying the oligosaccharide(s) attached to the glycosylation sites, e.g., using certain cell lines.

(295) Exemplary modifications, variants, and cell lines are described, e.g., in Patent Publication Nos. US 2003/0157108, US 2004/0093621, US 2003/0157108; WO 2000/61739; WO 2001/29246; US 2003/0115614; US 2002/0164328; US 2004/0093621; US 2004/0132140; US 2004/0110704; US 2004/0110282; US 2004/0109865; WO 2003/085119; WO 2003/084570; WO 2005/035586; WO 2005/035778; WO2005/053742; WO2002/031140; Okazaki et al.

Bioeng., 94(4):680-688 (2006); and WO2003/085107); WO 2003/011878 (Jean-Mairet et al.); U.S. Pat. No. 6,602,684 (Umana et al.); and US 2005/0123546 (Umana et al.); WO 1997/30087 (Patel et al.); WO 1998/58964 (Raju, S.); and WO 1999/22764 (Raju, S.).

(296) Among the modified antibodies are those having one or more amino acid modifications in the Fc region, such as those having a human Fc region sequence or other portion of a constant region (e.g., a human IgG1, IgG2, IgG3 or IgG4 Fc region) comprising an amino acid modification (e.g., a substitution) at one or more amino acid positions.

(297) Such modifications can be made, e.g., to improve half-life, alter binding to one or more types of Fc receptors, and/or alter effector functions.

(298) Also among the variants are cysteine engineered antibodies such as thioMAbs and other cysteine engineered variants, in which one or more residues of an antibody are substituted with cysteine residues, in order to generate reactive thiol groups at accessible sites, e.g., for use in conjugation of agents and linker-agents, to produce immunoconjugates. Cysteine engineered antibodies are described, e.g., in U.S. Pat. Nos. 7,855,275 and 7,521,541.

(299) In some embodiments, the antibodies are modified to contain additional nonproteinaceous moieties, including water soluble polymers. Exemplary polymers include, but are not limited to, polyethylene glycol (PEG), copolymers of ethylene glycol/propylene glycol, carboxymethylcellulose, dextran, polyvinyl alcohol, polyvinyl pyrrolidone, poly-1,3-dioxolane, poly-1,3,6-trioxane, ethylene/maleic anhydride copolymer, polyaminoacids (either homopolymers or random copolymers), and dextran or poly(n-vinyl pyrrolidone)polyethylene glycol, propropylene glycol homopolymers, prolypropylene oxide/ethylene oxide co-polymers, polyoxyethylated polyols (e.g., glycerol), polyvinyl alcohol, and mixtures thereof. Polyethylene glycol propionaldehyde may have advantages in manufacturing due to its stability in water. The polymer may be of any molecular weight, and may be branched or unbranched. The number of polymers attached to the antibody may vary, and if more than one polymer is attached, they can be the same or different molecules. In general, the number and/or type of polymers used for derivatization can be determined based on considerations including, but not limited to, the particular properties or functions of the antibody to be improved, whether the antibody derivative will be used in a therapy under defined conditions, etc.

(300) 2. TCR-Like CARs

(301) In some embodiments, the antibody or antigen-binding portion thereof is expressed on cells as part of a recombinant receptor, such as an antigen receptor. Among the antigen receptors are functional non-TCR antigen receptors, such as chimeric antigen receptors (CARs). Generally, a CAR containing an antibody or antigen-binding fragment that exhibits TCR-like specificity directed against a peptide in the context of an MHC molecule also may be referred to as a TCR-like CAR.

(302) Thus, among the provided binding molecules, e.g., HPV 16 E6 or E7 binding molecules, are antigen receptors, such as those that include one of the provided antibodies, e.g., TCR-like antibodies. In some embodiments, the antigen receptors and other chimeric receptors specifically bind to a region or epitope of HPV16 E6 or E7, such as antigen receptors containing the provided anti-HPV 16 E6 or E7 antibodies or antibody fragments, e.g. TCR-like antibodies. Among the antigen receptors are functional non-TCR antigen receptors, such as chimeric antigen receptors (CARs). Also provided are cells expressing the CARs and uses thereof in adoptive cell therapy, such as treatment of diseases and disorders associated with HPV 16 E6 or E7 expression.

(303) Thus, provided herein are TCR-like CARs that contain a non-TCR molecule that exhibits T cell receptor specificity, such as for a T cell epitope or peptide epitope when displayed or presented in the context of an MHC molecule. In some embodiments, a TCR-like CAR can contain an antibody or antigen-binding portion thereof, e.g., TCR-like antibody, such as described herein. In some embodiments, the antibody or antibody-binding portion thereof is reactive against specific peptide epitope in the context of an MHC molecule, wherein the antibody or antibody fragment can differentiate the specific peptide in the context of the MHC molecule from the MHC molecule alone, the specific peptide alone, and, in some cases, an irrelevant peptide in the context of an MHC molecule. In some embodiments, an antibody or antigen-binding portion thereof can exhibit a higher binding affinity than a T cell receptor.

(304) Exemplary antigen receptors, including CARs, and methods for engineering and introducing such receptors into cells, include those described, for example, in international patent application publication numbers WO2000/14257, WO2013/126726, WO2012/129514, WO2014/031687, WO2013/166321, WO2013/071154, WO2013/123061 U.S. patent application publication numbers US2002/131960, US2013/287748, US2013/0149337, U.S. Pat. Nos. 6,451,995, 7,446,190, 8,252,592, 8,339,645, 8,398,282, 7,446,179, 6,410,319, 7,070,995, 7,265,209, 7,354,762, 7,446,191, 8,324,353, and 8,479,118, and European patent application number EP2537416, and/or those described by Sadelain et al., Cancer Discov. 2013 April; 3(4): 388-398; Davila et al. (2013) PLoS ONE 8(4): e61338; Turtle et al., Curr. Opin. Immunol., 2012 October; 24(5): 633-39; Wu et al., Cancer, 2012 Mar. 18(2): 160-75. In some aspects, the antigen receptors include a CAR as described in U.S. Pat. No. 7,446,190, and those described in International Patent Application Publication No.: WO2014/055668 A1. Exemplary of the CARs include CARs as disclosed in any of the aforementioned publications, such as WO2014/031687, U.S. Pat. Nos. 8,339,645, 7,446,179, US 2013/0149337, U.S. Pat. Nos. 7,446,190, 8,389,282, e.g., and in which the antigen-binding portion, e.g., scFv, is replaced by an antibody, e.g., as provided herein.

(305) In some embodiments, the CARs generally include an extracellular antigen (or ligand) binding domain, including as an antibody or antigen-binding fragment thereof specific for a peptide in the context of an MHC molecule, linked to one or more intracellular signaling components, in some aspects via linkers and/or transmembrane domain(s). In some embodiments, such molecules can typically mimic or approximate a signal through a natural antigen receptor, such as a TCR, and, optionally, a signal through such a receptor in combination with a costimulatory receptor.

(306) In some embodiments, the CAR typically includes in its extracellular portion one or more antigen binding molecules, such as one or more antigen-binding fragment, domain, or portion, or one or more antibody variable domains, and/or antibody molecules. In some embodiments, the CAR includes an antigen-binding portion or portions of an antibody molecule, such as a single-chain antibody fragment (scFv) derived from the variable heavy (VH) and variable light (VL) chains of a monoclonal antibody (mAb). In some embodiments, the CAR contains a TCR-like antibody, such as an antibody or an antigen-binding fragment (e.g., scFv) that specifically recognizes a peptide epitope presented on the cell surface in the context of an MHC molecule.

(307) In some aspects, the antigen-specific binding, or recognition component is linked to one or more transmembrane and intracellular signaling domains. In some embodiments, the CAR includes a transmembrane domain fused to the extracellular domain of the CAR. In one embodiment, the transmembrane domain that naturally is associated with one of the domains in the CAR is used. In some instances, the transmembrane domain is selected or modified by amino acid substitution to avoid binding of such domains to the transmembrane domains of the same or different surface membrane proteins to minimize interactions with other members of the receptor complex.

(308) The transmembrane domain in some embodiments is derived either from a natural or from a synthetic source. Where the source is natural, the domain in some aspects is derived from any membrane-bound or transmembrane protein. Transmembrane regions include those derived from (i.e. comprise at least the transmembrane region(s) of) the alpha, beta or zeta chain of the T-cell receptor, CD28, CD3 epsilon, CD45, CD4, CD5, CD8, CD9, CD16, CD22, CD33, CD37, CD64, CD80, CD86, CD134, CD137, CD154. Alternatively the transmembrane domain in some embodiments is synthetic. In some aspects, the synthetic transmembrane domain comprises predominantly hydrophobic residues such as leucine and valine. In some aspects, a triplet of phenylalanine, tryptophan and valine will be found at each end of a synthetic transmembrane domain.

(309) In some embodiments, a short oligo- or polypeptide linker, for example, a linker of between 2 and 10 amino acids in length, such as one containing glycines and serines, e.g., glycine-serine doublet, is present and forms a linkage between the transmembrane domain and the cytoplasmic signaling domain of the CAR.

(310) In some embodiments, the CAR, e.g., TCR-like CAR, such as the antibody portion thereof, further includes a spacer, which may be or include at least a portion of an immunoglobulin constant region or variant or modified version thereof, such as a hinge region, e.g., an IgG4 hinge region, and/or a CH1/CL and/or Fc region. In some embodiments, the constant region or portion is of a human IgG, such as IgG4 or IgG1. In some aspects, the portion of the constant region serves as a spacer region between the antigen-recognition component, e.g., scFv, and transmembrane domain. The spacer can be of a length that provides for increased responsiveness of the cell following antigen binding, as compared to in the absence of the spacer. In some examples, the spacer is at or about 12 amino acids in length or is no more than 12 amino acids in length. Exemplary spacers include those having at least about 10 to 229 amino acids, about 10 to 200 amino acids, about 10 to 175 amino acids, about 10 to 150 amino acids, about 10 to 125 amino acids, about 10 to 100 amino acids, about 10 to 75 amino acids, about 10 to 50 amino acids, about 10 to 40 amino acids, about 10 to 30 amino acids, about 10 to 20 amino acids, or about 10 to 15 amino acids, and including any integer between the endpoints of any of the listed ranges. In some embodiments, a spacer region has about 12 amino acids or less, about 119 amino acids or less, or about 229 amino acids or less. Exemplary spacers include IgG4 hinge alone, IgG4 hinge linked to CH2 and CH3 domains, or IgG4 hinge linked to the CH3 domain. Exemplary spacers include, but are not limited to, those described in Hudecek et al. (2013) Clin. Cancer Res., 19:3153 or international patent application publication number WO2014/031687.

(311) In some embodiments, the constant region or portion is of a human IgG, such as IgG4 or IgG1. In some embodiments, the spacer has the sequence ESKYGPPCPPCP (set forth in SEQ ID NO: 268), and is encoded by the sequence set forth in SEQ ID NO: 269. In some embodiments, the spacer has the sequence set forth in SEQ ID NO: 270. In some embodiments, the spacer has the sequence set forth in SEQ ID NO: 271. In some embodiments, the constant region or portion is of IgD. In some embodiments, the spacer has the sequence set forth in SEQ ID NO: 272. In some embodiments, the spacer has a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to any of SEQ ID NOS: 268, 270, 271, or 272.

(312) The antigen recognition domain generally is linked to one or more intracellular signaling components, such as signaling components that mimic activation through an antigen receptor complex, such as a TCR complex, in the case of a CAR, and/or signal via another cell surface receptor. Thus, in some embodiments, the antibody or antigen-binding fragment thereof is linked to one or more transmembrane and intracellular signaling domains. In some embodiments, the transmembrane domain is fused to the extracellular domain. In one embodiment, a transmembrane domain that naturally is associated with one of the domains in the receptor, e.g., CAR, is used. In some instances, the transmembrane domain is selected or modified by amino acid substitution to avoid binding of such domains to the transmembrane domains of the same or different surface membrane proteins to minimize interactions with other members of the receptor complex.

(313) The transmembrane domain in some embodiments is derived either from a natural or from a synthetic source. Where the source is natural, the domain in some aspects is derived from any membrane-bound or transmembrane protein. Transmembrane regions include those derived from (i.e. comprise at least the transmembrane region(s) of) the alpha, beta or zeta chain of the T-cell receptor, CD28, CD3 epsilon, CD45, CD4, CD5, CD8, CD9, CD 16, CD22, CD33, CD37, CD64, CD80, CD86, CD134, CD137, CD154. Alternatively the transmembrane domain in some embodiments is synthetic. In some aspects, the synthetic transmembrane domain comprises predominantly hydrophobic residues such as leucine and valine. In some aspects, a triplet of phenylalanine, tryptophan and valine will be found at each end of a synthetic transmembrane domain. In some embodiments, the linkage is by linkers, spacers, and/or transmembrane domain(s).

(314) Among the intracellular signaling domains are those that mimic or approximate a signal through a natural antigen receptor, a signal through such a receptor in combination with a costimulatory receptor, and/or a signal through a costimulatory receptor alone. In some embodiments, a short oligo- or polypeptide linker, for example, a linker of between 2 and 10 amino acids in length, such as one containing glycines and serines, e.g., glycine-serine doublet, is present and forms a linkage between the transmembrane domain and the cytoplasmic signaling domain of the CAR.

(315) The CAR generally includes at least one intracellular signaling component or components. In some embodiments, the CAR includes an intracellular component of the TCR complex, such as a TCR CD3.sup.+ chain that mediates T-cell activation and cytotoxicity, e.g., CD3 zeta chain. Thus, in some aspects, the antigen binding molecule is linked to one or more cell signaling modules. In some embodiments, cell signaling modules include CD3 transmembrane domain, CD3 intracellular signaling domains, and/or other CD transmembrane domains. In some embodiments, the CAR further includes a portion of one or more additional molecules such as Fc receptor ?, CD8, CD4, CD25, or CD16. For example, in some aspects, the CAR includes a chimeric molecule between CD3-zeta (CD3-?) or Fc receptor ? and CD8, CD4, CD25 or CD16.

(316) In some embodiments, upon ligation of the CAR, the cytoplasmic domain or intracellular signaling domain of the CAR activates at least one of the normal effector functions or responses of the immune cell, e.g., T cell engineered to express the CAR. For example, in some contexts, the CAR induces a function of a T cell such as cytolytic activity or T-helper activity, such as secretion of cytokines or other factors. In some embodiments, a truncated portion of an intracellular signaling domain of an antigen receptor component or costimulatory molecule is used in place of an intact immunostimulatory chain, for example, if it transduces the effector function signal. In some embodiments, the intracellular signaling domain or domains include the cytoplasmic sequences of the T cell receptor (TCR), and in some aspects also those of co-receptors that in the natural context act in concert with such receptor to initiate signal transduction following antigen receptor engagement, and/or any derivative or variant of such molecules, and/or any synthetic sequence that has the same functional capability.

(317) In the context of a natural TCR, full activation generally requires not only signaling through the TCR, but also a costimulatory signal. Thus, in some embodiments, to promote full activation, a component for generating secondary or co-stimulatory signal is also included in the CAR. In other embodiments, the CAR does not include a component for generating a costimulatory signal. In some aspects, an additional CAR is expressed in the same cell and provides the component for generating the secondary or costimulatory signal. In some aspects, the cell comprises a first CAR which contains signaling domains to induce the primary signal and a second CAR which binds to a second antigen and contains the component for generating a costimulatory signal. For example, a first CAR can be an activating CAR and the second CAR can be a costimulatory CAR. In some aspects, both CARs must be ligated in order to induce a particular effector function in the cell, which can provide specificity and selectivity for the cell type being targeted.

(318) T cell activation is in some aspects described as being mediated by two classes of cytoplasmic signaling sequences: those that initiate antigen-dependent primary activation through the TCR (primary cytoplasmic signaling sequences), and those that act in an antigen-independent manner to provide a secondary or co-stimulatory signal (secondary cytoplasmic signaling sequences). In some aspects, the CAR includes one or both of such signaling components.

(319) In some aspects, the CAR includes a primary cytoplasmic signaling sequence that regulates primary activation of the TCR complex. Primary cytoplasmic signaling sequences that act in a stimulatory manner may contain signaling motifs which are known as immunoreceptor tyrosine-based activation motifs or ITAMs. Examples of ITAM containing primary cytoplasmic signaling sequences include those derived from TCR or CD3 zeta, FcR gamma, CD3 gamma, CD3 delta or CD3 epsilon. In some embodiments, cytoplasmic signaling molecule(s) in the CAR contain(s) a cytoplasmic signaling domain, portion thereof, or sequence derived from CD3 zeta.

(320) In some embodiments, the CAR includes a signaling domain and/or transmembrane portion of a costimulatory receptor, such as CD28, 4-1BB, OX40, DAP10, and ICOS. In some aspects, the same CAR includes both the activating and costimulatory components; in other aspects, the activating domain is provided by one CAR whereas the costimulatory component is provided by another CAR recognizing another antigen.

(321) In some embodiments, the activating domain is included within one CAR, whereas the costimulatory component is provided by another chimeric receptor recognizing another antigen. In some embodiments, the CARs include activating or stimulatory CARs, and costimulatory receptors, both expressed on the same cell (see WO2014/055668). In some aspects, the HPV 16 E6 or E7 antibody-containing receptor is the stimulatory or activating CAR; in other aspects, it is the costimulatory receptor. In some embodiments, the cells further include inhibitory CARs (iCARs, see Fedorov et al., Sci. Transl. Medicine, 5(215) (December, 2013)), such as an inhibitory receptor recognizing a peptide epitope other than HPV 16 E6 or HPV16 E7, whereby an activating signal delivered through the HPV 16-targeting CAR is diminished or inhibited by binding of the inhibitory CAR to its ligand, e.g., to reduce off-target effects.

(322) In some embodiments, the cell expressing the provided TCR or other binding molecule further expresses an additional receptor, such as a receptor capable of delivering a costimulatory or survival-promoting signal, such as a costimulatory receptor (see WO2014/055668) and/or to block or change the outcome of an inhibitory signal, such as one typically delivered via an immune checkpoint or other immunoinhibitory molecule, such as one expressed in the tumor microenvironment, e.g., in order to promote increased efficacy of such engineered cells. See, e.g., Tang et al., Am J Transl Res. 2015; 7(3): 460-473. In some embodiments, the cell may further include one or more other exogenous or recombinant or engineered components, such as one or more exogenous factors and/or costimulatory ligands, which are expressed on or in or secreted by the cells and can promote function, e.g., in the microenviroment. Exemplary of such ligands and components include, e.g., TNFR and/or Ig family receptors or ligands, e.g., 41BBL, CD40, CD40L, CD80, CD86, cytokines, chemokines, and/or antibodies or other molecules, such as scFvs. See, e.g., patent application publication Nos WO2008121420 A1, WO2014134165 A1, US20140219975 A1. In some embodiments, the cells comprise one or more inhibitory receptor (iCARs, see Fedorov et al., Sci. Transl. Medicine, 5(215) (December, 2013)), such as one that binds to a ligand or antigen not associated with the disease or condition or not expressed therein or thereon.

(323) In certain embodiments, the intracellular signaling domain comprises a CD28 transmembrane and signaling domain linked to a CD3 (e.g., CD3-zeta) intracellular domain. In some embodiments, the intracellular signaling domain comprises a chimeric CD28 and CD137 (4-1BB, TNFRSF9) co-stimulatory domains, linked to a CD3 zeta intracellular domain.

(324) In some embodiments, the CAR encompasses one or more, e.g., two or more, costimulatory domains and an activation domain, e.g., primary activation domain, in the cytoplasmic portion. Exemplary CARs include intracellular components of CD3-zeta, CD28, and 4-1BB.

(325) In some embodiments, the cell expressing the CAR or other antigen receptor further includes a marker, such as a cell surface marker, which may be used to confirm transduction or engineering of the cell to express the receptor, such as a truncated version of a cell surface receptor, such as truncated EGFR (tEGFR). Exemplary surrogate markers can include truncated forms of cell surface polypeptides, such as truncated forms that are non-functional and to not transduce or are not capable of transducing a signal or a signal ordinarily transduced by the full-length form of the cell surface polypeptide, and/or do not or are not capable of internalizing Exemplary truncated cell surface polypeptides including truncated forms of growth factors or other receptors such as a truncated human epidermal growth factor receptor 2 (tHER2), a truncated epidermal growth factor receptor (tEGFR, exemplary tEGFR sequence set forth in SEQ ID NO: 273 or 343) or a prostate-specific membrane antigen (PSMA) or modified form thereof tEGFR may contain an epitope recognized by the antibody cetuximab (Erbitux?) or other therapeutic anti-EGFR antibody or binding molecule, which can be used to identify or select cells that have been engineered with the tEGFR construct and an encoded exogenous protein, and/or to eliminate or separate cells expressing the encoded exogenous protein. See U.S. Pat. No. 8,802,374 and Liu et al., Nature Biotech. 2016 April; 34(4): 430-434). In some aspects, the marker, e.g. surrogate marker, includes all or part (e.g., truncated form) of CD34, a NGFR, a CD19 or a truncated CD19, e.g., a truncated non-human CD19, or epidermal growth factor receptor (e.g., tEGFR). In some embodiments, the marker is or comprises a fluorescent protein, such as green fluorescent protein (GFP), enhanced green fluorescent protein (EGFP), such as super-fold GFP (sfGFP), red fluorescent protein (RFP), such as tdTomato, mCherry, mStrawberry, AsRed2, DsRed or DsRed2, cyan fluorescent protein (CFP), blue green fluorescent protein (BFP), enhanced blue fluorescent protein (EBFP), and yellow fluorescent protein (YFP), and variants thereof, including species variants, monomeric variants, and codon-optimized and/or enhanced variants of the fluorescent proteins. In some embodiments, the marker is or comprises an enzyme, such as a luciferase, the lacZ gene from E. coli, alkaline phosphatase, secreted embryonic alkaline phosphatase (SEAP), chloramphenicol acetyl transferase (CAT). Exemplary light-emitting reporter genes include luciferase (luc), ?-galactosidase, chloramphenicol acetyltransferase (CAT), ?-glucuronidase (GUS) or variants thereof.

(326) In some embodiments, the marker is a selection marker. In some embodiments, the selection marker is or comprises a polypeptide that confers resistance to exogenous agents or drugs. In some embodiments, the selection marker is an antibiotic resistance gene. In some embodiments, the selection marker is an antibiotic resistance gene confers antibiotic resistance to a mammalian cell. In some embodiments, the selection marker is or comprises a Puromycin resistance gene, a Hygromycin resistance gene, a Blasticidin resistance gene, a Neomycin resistance gene, a Geneticin resistance gene or a Zeocin resistance gene or a modified form thereof.

(327) In some aspects, the marker includes all or part (e.g., truncated form) of CD34, a NGFR, or epidermal growth factor receptor (e.g., tEGFR). In some embodiments, the nucleic acid encoding the marker is operably linked to a polynucleotide encoding for a linker sequence, such as a cleavable linker sequence, e.g., T2A. See WO2014031687. In some embodiments, introduction of a construct encoding the CAR and EGFRt separated by a T2A ribosome switch can express two proteins from the same construct, such that the EGFRt can be used as a marker to detect cells expressing such construct. In some embodiments, a marker, and optionally a linker sequence, can be any as disclosed in published patent application No. WO2014031687. For example, the marker can be a truncated EGFR (tEGFR) that is, optionally, linked to a linker sequence, such as a T2A cleavable linker sequence. An exemplary polypeptide for a truncated EGFR (e.g. tEGFR) comprises the sequence of amino acids set forth in SEQ ID NO: 273 or 343 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 273 or 343. An exemplary T2A linker sequence comprises the sequence of amino acids set forth in SEQ ID NO: 211 or 274 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 211 or 274.

(328) In some embodiments, the marker is a molecule, e.g., cell surface protein, not naturally found on T cells or not naturally found on the surface of T cells, or a portion thereof.

(329) In some embodiments, the molecule is a non-self molecule, e.g., non-self protein, i.e., one that is not recognized as self by the immune system of the host into which the cells will be adoptively transferred.

(330) In some embodiments, the marker serves no therapeutic function and/or produces no effect other than to be used as a marker for genetic engineering, e.g., for selecting cells successfully engineered. In other embodiments, the marker may be a therapeutic molecule or molecule otherwise exerting some desired effect, such as a ligand for a cell to be encountered in vivo, such as a costimulatory or immune checkpoint molecule to enhance and/or dampen responses of the cells upon adoptive transfer and encounter with ligand.

(331) In some cases, CARs are referred to as first, second, and/or third generation CARs. In some aspects, a first generation CAR is one that solely provides a CD3-chain induced signal upon antigen binding; in some aspects, a second-generation CARs is one that provides such a signal and costimulatory signal, such as one including an intracellular signaling domain from a costimulatory receptor such as CD28 or CD137; in some aspects, a third generation CAR in some aspects is one that includes multiple costimulatory domains of different costimulatory receptors.

(332) In some embodiments, the chimeric antigen receptor includes an extracellular portion containing a TCR-like antibody or fragment described herein and an intracellular signaling domain. In some embodiments, the antibody or fragment includes a scFv and the intracellular domain contains an ITAM. In some aspects, the intracellular signaling domain includes a signaling domain of a zeta chain of a CD3-zeta (CD3?) chain. In some embodiments, the chimeric antigen receptor includes a transmembrane domain linking the extracellular domain and the intracellular signaling domain. In some aspects, the transmembrane domain contains a transmembrane portion of CD28. The extracellular domain and transmembrane can be linked directly or indirectly. In some embodiments, the extracellular domain and transmembrane are linked by a spacer, such as any described herein. In some embodiments, the chimeric antigen receptor contains an intracellular domain of a T cell costimulatory molecule, such as between the transmembrane domain and intracellular signaling domain. In some aspects, the T cell costimulatory molecule is CD28 or 41BB.

In some such embodiments, the CAR further includes a spacer containing a portion of an Ig molecule, such as a human Ig molecule, such as an Ig hinge, e.g. an IgG4 hinge, such as a hinge-only spacer.

(334) In some embodiments, the transmembrane domain of the receptor, e.g., the TCR-like CAR, is a transmembrane domain of human CD28 (e.g., Accession No. P01747.1) or variant thereof, such as a transmembrane domain that comprises the sequence of amino acids set forth in SEQ ID NO: 275 or a sequence of amino acids that exhibits at least 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 275. In some embodiments, the transmembrane-domain containing portion of the CAR comprises the sequence of amino acids set forth in SEQ ID NO: 276 or a sequence of amino acids having at least at or about 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to SEQ ID NO: 276.

(335) In some embodiments, the intracellular signaling component(s) of the CAR, e.g., the TCR-like CAR, contains an intracellular costimulatory signaling domain of human CD28 or a functional variant or portion thereof, such as a domain with an LL to GG substitution at positions 186-187 of a native CD28 protein.

(337) In some aspects, the spacer contains only a hinge region of an IgG, such as only a hinge of IgG4 or IgG1, such as the hinge only spacer set forth in SEQ ID NO: 268. In other embodiments, the spacer is or contains an Ig hinge, e.g., an IgG4-derived hinge, optionally linked to a CH2 and/or CH3 domains.

(341) 3. Exemplary Features of Bin Ding Molecules and Engineered Cells

(342) In some aspects, the provided binding molecules, e.g. TCRs or TCR-like CAR have one or more specified functional features, such as binding properties, including binding to particular epitopes, lack of off-target binding or activity and/or particular binding affinities. In some embodiments, any one or more of the features of a provided TCR can be assessed by expressing the TCR, e.g., by introducing one or more nucleic acid encoding the TCR, into a T cell, such a primary T cell or a T cell line. In some embodiments, the T cell line is a Jurkat cell or a Jurkat-derived cell line. Exemplary of a Jurkat-derived cell line is the J.RT3-T3.5 (ATCC? TIB-153TM) cell line, produced by treatment of the Jurkat leukemia cell line with irradiation mutagenesis and negative selection with OKT3 monoclonal antibody (see Weiss & Stobo, J. Ex. Med. 160(5):1284-1299 (1984)).

(343) In some embodiments, the provided binding molecules are capable of binding to a peptide epitope of HPV16, e.g. an epitope of HPV 16 E6 or E7 such as described above, with at least a certain affinity, as measured by any of a number of known methods. In some embodiments, the peptide epitope is a peptide in the context of an MHC molecule or ligand. In some embodiments, the affinity is represented by an equilibrium dissociation constant (K.sub.D) or an association constant (k.sub.a). In some embodiments, the affinity is represented by EC.sub.50.

(344) In some embodiments, the binding molecule, e.g., TCR, binds, such as specifically binds, to a peptide epitope, e.g., in complex with an MHC molecule, with an affinity or K.sub.A (i.e., an equilibrium association constant of a particular binding interaction with units of 1/M; equal to the ratio of the on-rate [k.sub.on or k.sub.a] to the off-rate [k.sub.off or k.sub.d] for this association reaction, assuming bimolecular interaction) equal to or greater than 10.sup.5 M.sup.?1. In some embodiments, the TCR or fragment thereof exhibits a binding affinity for the peptide epitope with a K.sub.D (i.e., an equilibrium dissociation constant of a particular binding interaction with units of M; equal to the ratio of the off-rate [k.sub.off or k.sub.d] to the on-rate [k.sub.on or k.sub.a] for this association reaction, assuming bimolecular interaction) of equal to or less than 10.sup.?5 M. For example, the equilibrium dissociation constant K.sub.D ranges from or from about 10.sup.?5 M to or to about 10.sup.?12 M, such as from or from about 10.sup.?6 M to or to about 10.sup.?10 M, from or from about 10.sup.?7 M to or to about 10.sup.?11 M, from or from about 10.sup.?6 M to or to about 10.sup.?8 M, or from or from about 10.sup.?7 M to or to about 10.sup.?8 M. The on-rate (association rate constant; k.sub.on or k.sub.a; units of 1/Ms) and the off-rate (dissociation rate constant; k.sub.off or k.sub.d; units of 1/s) can be determined using any of the assay methods known in the art, for example, surface plasmon resonance (SPR).

(345) In some embodiments, binding affinity may be classified as high affinity or as low affinity. In some cases, the binding molecule (e.g. TCR) that exhibits low to moderate affinity binding exhibits a K.sub.A of up to 10.sup.7 M.sup.?1, up to 10.sup.6M.sup.?1, up to 10.sup.5 M.sup.?1. In some cases, a binding molecule (e.g. TCR) that exhibits high affinity binding to a particular epitope interacts with such epitope with a K.sub.A of at least 10.sup.7 M.sup.?1, at least 10.sup.8M.sup.?1, at least 10.sup.9M.sup.?1, at least 10.sup.10 M.sup.?1, at least 10.sup.11 M.sup.?1, at least 10.sup.12 M.sup.?1, or at least 10.sup.13 M.sup.?1. In some embodiments, the binding affinity (EC.sub.50) and/or the dissociation constant of the binding molecule to a peptide epitope of HPV 16 E6 or E7 is from or from about 0.1 nM to 1 ?M, 1 nM to 1 ?M, 1 nM to 500 nM, 1 nM to 100 nM, 1 nM to 50 nM, 1 nM to 10 nM, 10 nM to 500 nM, 10 nM to 100 nM, 10 nM to 50 nM, 50 nM to 500 nM, 50 nM to 100 nM or 100 nM to 500 nM. In certain embodiments, the binding affinity (EC.sub.50) and/or the dissociation constant of the binding molecule to a peptide epitope of HPV 16 E6 or E7 is at or about or less than at or about 1 ?M, 500 nm, 100 nM, 50 nM, 40 nM, 30 nM, 25 nM, 20 nM, 19 nM, 18 nM, 17 nM, 16 nM, 15 nM, 14 nM, 13 nM, 12 nM, 11 nM, 10 nM, 9 nM, 8 nM, 7 nM, 6 nM, 5 nM, 4 nM, 3 nM, 2 nM, or 1 nM.

(346) A variety of assays are known for assessing binding affinity and/or determining whether a binding molecule specifically binds to a particular ligand (e.g. peptide in the context of an MHC molecule). It is within the level of a skilled artisan to determine the binding affinity of a binding molecule, e.g., TCR, for a T cell epitope of a target polypeptide, such as by using any of a number of binding assays that are well known in the art. For example, in some embodiments, a BIAcore machine can be used to determine the binding constant of a complex between two proteins. The dissociation constant for the complex can be determined by monitoring changes in the refractive index with respect to time as buffer is passed over the chip. Other suitable assays for measuring the binding of one protein to another include, for example, immunoassays such as enzyme linked immunosorbent assays (ELISA) and radioimmunoassays (RIA), or determination of binding by monitoring the change in the spectroscopic or optical properties of the proteins through fluorescence, UV absorption, circular dichroism, or nuclear magnetic resonance (NMR). Other exemplary assays include, but are not limited to, Western blot, ELISA, analytical ultracentrifugation, spectroscopy and surface plasmon resonance (Biacore?) analysis (see, e.g., Scatchard et al., Ann. N.Y. Acad. Sci. 51:660, 1949; Wilson, Science 295:2103, 2002; Wolff et al., Cancer Res. 53:2560, 1993; and U.S. Pat. Nos. 5,283,173, 5,468,614, or the equivalent), flow cytometry, sequencing and other methods for detection of expressed nucleic acids. In one example, apparent affinity for a TCR is measured by assessing binding to various concentrations of tetramers, for example, by flow cytometry using labeled tetramers. In one example, apparent K.sub.D of a TCR is measured using 2-fold dilutions of labeled tetramers at a range of concentrations, followed by determination of binding curves by non-linear regression, apparent K.sub.D being determined as the concentration of ligand that yielded half-maximal binding.

(347) In some embodiments, the binding molecules display a binding preference for antigen recognition of HPV 16 E6- or E7-expressing cells as compared to HPV 16 E6- or E7-negative cells, such as particular cells known and/or described herein to express HPV 16 E6 or E7 and known not to express HPV 16 E6 or E7. In some embodiments, the binding preference is observed where a significantly greater degree of binding is measured to the HPV 16 E6- or E7-expressing, as compared to the non-HPV 16 E6- or E7-expressing cells. In some embodiments, the fold change in degree of binding detected, for example, as measured by mean fluorescence intensity in a flow cytometry-based assay and/or dissociation constant or EC.sub.50, to the HPV 16 E6- or E7-expressing cells as compared to the non-HPV 16 E6- or E7-expressing cells, is at least at or about 1.5, 2, 3, 4, 5, 6, or more.

(348) In some embodiments, the binding molecule, e.g. TCR, does not exhibit cross-reactive or off-target binding, such as undesirable off-target binding, e.g. off-target binding to antigens present in healthy or normal tissues or cells. In some embodiments, the binding molecule, e.g. TCR, recognizes, such as specifically binds, only one peptide epitope or antigen complex, such as recognizes only a particular HPV 16 E6 or E7 epitope set forth in any of SEQ ID NOs: 232-239 or an antigen complex thereof. Thus, in some embodiments, the provided binding molecules, e.g. TCRs, have a reduced risk of causing unwanted side effects due to, for example, recognition of a non-target peptide epitope.

(349) In some embodiments, the binding molecule, e.g., TCR, does not recognize, such as does not specifically bind, a sequence-related peptide epitope of the HPV 16 E6 or E7 epitope set forth in any of SEQ ID NOS: 232-239, i.e., does not recognize an epitope sharing some amino acids in common with an HPV 16 E6 or E7 epitope set forth in any of SEQ ID NOS: 232-239, such as does not recognize an epitope that differs in 1, 2, 3, 4, 5 or 6 amino acid residues from such epitope when the epitopes are aligned. In some embodiments, the binding molecule, e.g., TCR, does not recognize a sequence-unrelated epitope of the HPV 16 E6 or E7 epitope set forth in any of SEQ ID NOS: 232-239, i.e., does not recognize an epitope that is substantially different in sequence compared to an HPC 16 E6 or E7 epitope set forth in any of SEQ ID NOS: 232-239, such as differing in more than 6, 7, 8, 9, 10 or more amino acid residues from such epitope when the epitopes are aligned. In some embodiments, the binding molecule, e.g., TCR, does not recognize the HPV 16 E6 or E7 epitope set forth in any of SEQ ID NOS: 232-239 in the context of a different MHC allele, such as in the context of an MHC allele other than HLA-A2.

(350) Typically, specific binding of binding molecule, e.g. TCR, to a peptide epitope, e.g. in complex with an MHC, is governed by the presence of an antigen-binding site containing one or more complementarity determining regions (CDRs). In general, it is understood that specifically binds does not mean that the particular peptide epitope, e.g. in complex with an MHC, is the only thing to which the MHC-peptide molecule may bind, since non-specific binding interactions with other molecules may also occur. In some embodiments, binding of binding molecule to a peptide in the context of an MHC molecule is with a higher affinity than binding to such other molecules, e.g. another peptide in the context of an MHC molecule or an irrelevant (control) peptide in the context of an MHC molecule, such as at least about 2-fold, at least about 10-fold, at least about 20-fold, at least about 50-fold, or at least about 100-fold higher than binding affinity to such other molecules.

(351) In some embodiments, the binding molecule, e.g., TCR, can be assessed for safety or off-target binding activity using any of a number of screening assays known in the art. In some embodiments, generation of an immune response to a particular binding molecule, e.g., TCR, can be measured in the presence of cells that are known not to express the target peptide epitope, such as cells derived from normal tissue(s), allogenic cell lines that express one or more different MHC types or other tissue or cell sources. In some embodiments, the cells or tissues include normal cells or tissues. For example, in some cases, cells or tissues can include brain, muscle, liver, colon, kidney, lung, ovary, placenta, heart, pancreas, prostate, epithelium or skin, testis, adrenal, intestine, bone marrow or spleen. In some embodiments, the binding to cells can be tested in 2 dimensional cultures. In some embodiments, the binding to cells can be tested in 3 dimensional cultures. In some embodiments, as a control, the tissues or cells can be ones that are known to express the target epitope. The immune response can be assessed directly or indirectly, such as by assessing activation of immune cells such as T cells (e.g. cytotoxic activity), production of cytokine (e.g. interferon gamma), or activation of a signaling cascade.

(352) In some embodiments, potential off-targets can be identified by performing a homology scan of the human genome using the particular target epitope, e.g., to identify potential sequence-related epitopes. In some cases, a protein sequence database can be analyzed to identify peptides with similarity to the target peptide epitope. In some embodiments, to facilitate identification of potential sequence-related epitopes of interest, a binding motif can first be identified. In some embodiments, the binding motif can be identified by peptide scanning, such as an alanine mutagenesis scan, of the target epitope (e.g., HPV 16 E6 or E7 epitope set forth in any of SEQ ID NOS: 232-239) to identify the binding motif recognized by the binding molecule, see e.g. WO2014/096803. In some embodiments, the binding motif can be identified by mutagenesis of the target peptide so that a series of mutants are generated in which each amino acid or a subset thereof is changed to another amino acid residue, tested for its activity relative to the original target epitope, and those residues that are involved in or required for binding are identified. In some embodiments, a series of mutants may be made in which the amino acid residue at each position of the target epitope is mutated to all alternative amino acids. In some cases, once the binding motif is identified (i e amino acid residues that are non-tolerated and are involved in or are required for binding), protein databases may be searched for proteins that contain the binding motif.

(353) In some embodiments, suitable protein databases include but are not limited to UniProtKB/Swiss-Prot (http://www.uniprot.org/), Protein Information Resource (PI R) (http://pir.georgetown.edu/pirwww/index.shtml), and/or Reference Sequence (RefSeq) (www.ncbi.nlm.nih.gov/RefSeq). Searching for a peptide motif may be carried out using any one of a number of tools, which may be found on bioinformatics resource sites such as ExPASY (http://www.expasy.org/). For example, the search tool ScanProsite identifies user-defined motifs in all protein sequences in the UniProtKB/Swiss-Prot Protein Knowledgebase (De Castro et al. Nucleic Acids Res. 2006 Jul. 1; 34 (Web Server issue):W362-5). In some cases, the search may be carried out for peptides that are of human origin or of organisms which are commonly present in humans, such as viral or bacterial pathogens, or commensal bacteria.

(354) In some embodiments, if a potential off-target epitope is identified, the binding molecule, e.g., TCR, can be redesigned so that there is no longer any cross reactivity to the off target peptide(s), while maintaining binding, preferably with high affinity, to the target peptide epitope. For example, T cell receptors can be redesigned by mutagenesis using the methods described in WO 03/020763.

(355) In some embodiments, the binding molecules, e.g., engineered cells comprising the binding molecules, e.g., TCRs, elicit an immune response to HPV 16. In some embodiments, cytotoxic T lymphocytes (CTL) may be activated when cells containing the binding molecules, e.g., TCRs, are contacted with target cells, such as those that express HPV 16, such as HPV 16 E6 or HPV 16 E7. For example, cells containing the TCRs may induce lysis of target cells, such as HPV 16-expressing, e.g., HPV 16 E6- or E7-expressing cells. In some aspects, the ability of the binding molecules, such as cells expressing the binding molecules, e.g., TCRs or CARs, to elicit an immune response can be determined by measuring cytokine release. In some embodiments, in response to coculture with or exposure to cells expressing the binding molecules, e.g., TCRs or CARs, a variety of cytokines are released when the cells are stimulated by an appropriate target cell known to express HPV 16, such as HPV 16 E6 or HPV 16 E7. Non-limiting examples of such cytokines include IFN-?, TNF-?, and GM-CSF. Exemplary cells known to express HPV 16 include, but are not limited to, CaSki cells (ATCC No. CRL-1550, which contain about 600 copies of integrated HPV16) or other tumor cell expressing the relevant MHC molecule and the corresponding peptide epitope, e.g., HPV 16 E6 or E7 epitope, such as any of those set forth in SEQ ID NOs: 232-239.

(356) In some embodiments, CTL activation can be determined. A variety of techniques exist for assaying the activity of CTL. In some embodiments, CTL activity can be assessed by assaying the culture for the presence of CTLs that lyse radio-labeled target cells, such as specific peptide-pulsed targets. These techniques include the labeling of target cells with radionuclides such as Na.sub.2, .sup.51CrO.sub.4 or .sup.3H-thymidine, and measuring the release or retention of the radionuclides from the target cells as an index of cell death. In some embodiments, CTL are known to release a variety of cytokines when they are stimulated by an appropriate target cell, such as a tumor cell expressing the relevant MHC molecule and the corresponding peptide epitope, and the presence of such epitope-specific CTLs can be determined by measuring cytokine release. Non-limiting examples of such cytokines include IFN-?, TNF-?, and GM-CSF. Assays for these cytokines are well known in the art, and their selection is left to the skilled artisan. Methodology for measuring both target cell death and cytokine release as a measure of CTL reactivity are given in Coligan, J. E. et al. (Current Protocols in Immunology, 1999, John Wiley & Sons, Inc., New York).

(357) In some embodiments, cytokine production can be measured as an indicator of an immune response. In some cases, such measured cytokines can include, without limitation, interleukin-2 (IL-2), interferon-gamma (IFN?), interleukin-4 (IL-4), TNF-alpha, interleukin-6 (IL-6), interleukin-10 (IL-10), interleukin-12 (IL-12) or TGF-beta. Assays to measure cytokines are well known in the art, and include, without limitation, ELISA, intracellular cytokine staining, cytometric bead array, RT-PCR, ELISPOT, flow cytometry and bio-assays in which cells responsive to the relevant cytokine are tested for responsiveness (e.g. proliferation) in the presence of a test sample.

(358) In some embodiments, cells exposed to the binding molecules, e.g. cells containing the binding molecules, such as TCRs or CARs, are assessed for an immunological readout, such as using a T cell assay. In some embodiments, the binding molecule-containing cells can activate a CD8+ T cell response. In one embodiment, CD8+ T cell responses can be assessed by monitoring CTL reactivity using assays that include, but are not limited to, target cell lysis via .sup.51Cr release or detection of interferon gamma release, such as by enzyme-linked immunosorbent spot assay (ELISA), intracellular cytokine staining or ELISPOT. In some embodiments, the binding molecules, e.g., cells containing the binding molecules, such as TCRs or CARs, can activate a CD4+ T cell response. In some aspects, CD4+ T cell responses can be assessed by assays that measure proliferation, such as by incorporation of [31-1]-thymidine into cellular DNA and/or by the production of cytokines, such as by ELISA, intracellular cytokine staining or ELISPOT. In some cases, the cytokine can include, for example, interleukin-2 (IL-2), interferon-gamma (IFN-gamma), interleukin-4 (IL-4), TNF-alpha, interleukin-6 (IL-6), interleukin-10 (IL-10), interleukin-12 (IL-12) or TGF beta. In some embodiments, recognition or binding of the peptide epitope, such as a MHC class II epitope, by the binding molecule can elicit or activate a CD4+ T cell response and/or a CD8+ T cell response.

(359) In some embodiments, the binding specificity and/or function (e.g., ability to elicit an immune response to HPV 16) of the binding molecule, e.g., TCR or antigen-binding fragment thereof, is at least partially CD8-independent. In some cases, TCR recognition of a peptide in the context of an MHC molecule and subsequent T cell activation is facilitated in the presence of a CD8 co-receptor. For example, CD8 coreceptor engagement can facilitate lowto moderateTCR affinity interactions and/or T cell activation (See, for example, Kerry et al. J. Immunology (2003) 171(9): 4493-4503 and Robbins et al. J Immunology (2008) 180(9): 6116-6131). Among the provided binding molecules are molecules, e.g. TCRs, that exhibit CD8-independent binding for an HPV E6 or E7 peptide epitope. In some embodiments, such binding molecules, e.g. TCR, may have higher functional avidity or affinity than TCRs or antigen binding fragments thereof that require the presence of CD8 co-expression. In some aspects, the provided CD8-independent binding molecules, such as TCRs, can be expressed or engineered in cells, e.g. T cells, that do not express CD8, such as can be expressed or engineered in CD4+ cells. In some embodiments, among the provided engineered non-CD8-expressing cells, e.g. CD4+ cells, are cells expressing a recombinant binding molecule, e.g., TCR or antigen-binding fragment, that exhibit at least or at least about 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or more of the binding specificity, affinity and/or avidity for a peptide in the context of an MHC molecule as the same binding molecule (e.g., TCR or antigen-binding fragment thereof) that is expressed on a CD8+ T cell.

II. Nucleic Acids, Vectors and Methods of Expression

(360) Also provided are nucleic acids encoding any of the provided binding molecules, e.g., TCRs or antigen-binding fragments thereof or antibodies or antigen-binding fragments thereof or CARs containing such antibodies, such as those described herein. The nucleic acids may include those encompassing natural and/or non-naturally occurring nucleotides and bases, e.g., including those with backbone modifications. The terms nucleic acid molecule, nucleic acid, and polynucleotide may be used interchangeably, and refer to a polymer of nucleotides. Such polymers of nucleotides may contain natural and/or non-natural nucleotides, and include, but are not limited to, DNA, RNA, and PNA. Nucleic acid sequence refers to the linear sequence of nucleotides that comprise the nucleic acid molecule or polynucleotide.

(361) In some embodiments, the binding molecule, e.g. TCR, or antigen binding portion thereof may be a recombinantly produced natural protein or mutated form thereof in which one or more property, such as binding characteristic, has been altered. In some aspects, the nucleic acid is synthetic. In some cases, the nucleic acid is or contains cDNA. In some aspects, the nucleic acid molecule can be modified for use in the constructs described herein, such as for codon optimization. In some cases, the sequences can be designed to contain terminal restriction site sequences for purposes of cloning into vectors.

(362) In some embodiments, nucleic acid molecule encoding the binding molecule, e.g. TCR, can be obtained from a variety of sources, such as by polymerase chain reaction (PCR) amplification of encoding nucleic acids within or isolated from a given cell or cells. In some embodiments, the TCR is obtained from a biological source, such as from cells such as from a T cell (e.g. cytotoxic T cell), T cell hybridomas or other publicly available source. In some embodiments, a TCR may be derived from one of various animal species, such as human, mouse, rat, or other mammal, such as generally from a human. In some embodiments, the T cells can be obtained from in vivo isolated cells, such as from normal (or healthy) subjects or diseased subjects, including T cells present in peripheral blood mononuclear cells (PBMCs) or tumor-infiltrating lymphocytes (TILs). In some embodiments, the T cells can be a cultured T cell hybridoma or clone. For example, in some embodiments, to generate a vector encoding a TCR, the ? and ? chains can be PCR amplified from total cDNA isolated from a T cell clone expressing the TCR of interest and cloned into an expression vector. In some embodiments, the ? and ? chains can be synthetically generated. In some embodiments, the ? and ? chains are cloned into the same vector.

(363) In some embodiments, the TCR or antigen-binding portion thereof can be synthetically generated from knowledge of the sequence of the TCR.

(364) In some embodiments, the nucleic acid molecule contains a nucleic acid sequence encoding an alpha chain and/or a nucleotide sequence encoding a beta chain.

(365) In some embodiments, the nucleic acid sequence encoding the alpha chain comprises one of the following: residues 61-816 of SEQ ID NO: 20, residues 58-804 of SEQ ID NO: 30, residues 61-825 of SEQ ID NO: 40, residues 64-813 of SEQ ID NO: 50, residues 64-816 of SEQ ID NO: 60, residues 58-807 of SEQ ID NO: 70, residues 61-825 of SEQ ID NO: 80, residues 67-831 of SEQ ID NO: 90, residues 58-801 of SEQ ID NO: 100, residues 64-810 of SEQ ID NO: 183, residues 58-801 of SEQ ID NO: 202, residues 67-813 of SEQ ID NO: 219, a degenerate sequence thereof or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity thereto. In some aspects, the nucleotide sequence encoding the beta chain comprises one of the following: residues 58-936 of SEQ ID NO: 17, residues 58-930 of SEQ ID NO: 16, residues 58-939 of SEQ ID NO: 24, residues 64-930 of SEQ ID NO: 34 or 44, residues 58-933 of SEQ ID NO: 55, residues 58-927 of SEQ ID NO: 64, residues 64-936 of SEQ ID NO: 74, residues 58-933 of SEQ ID NO: 84, residues 63-930 of SEQ ID NO: 94, residues 46-936 of SEQ ID NO: 104, residues 58-933 of SEQ ID NO: 108, a degenerate sequence thereof or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity thereto.

(366) In some embodiments, the nucleotide sequence encoding the alpha chain and/or the nucleotide sequence encoding the beta chain is codon-optimized. Typically, codon optimization involves balancing the percentages of codons selected with the published abundance of human transfer RNAs so that none is overloaded or limiting. This may be necessary in some cases because most amino acids are encoded by more than one codon, and codon usage varies from organism to organism. Differences in codon usage between transfected genes and host cells can have effects on protein expression and immunogenicity of a nucleic acid construct. In general, for codon optimization, codons are chosen to select for those codons that are in balance with human usage frequency. Typically, the redundancy of the codons for amino acids is such that different codons code for one amino acid. In some embodiments, in selecting a codon for replacement, it may be desired that the resulting mutation is a silent mutation such that the codon change does not affect the amino acid sequence. Generally, the last nucleotide of the codon can remain unchanged without affecting the amino acid sequence.

(367) In some cases, the nucleic acid sequence encoding the alpha chain contains one of the following: residues 67-825 of SEQ ID NO: 10, residues 58-813 of SEQ ID NO: 11, residues 64-822 of SEQ ID NO: 12 residues 61-825 of SEQ ID NO: 21, residues 58-813 of SEQ ID NO: 31, residues 61-834 of SEQ ID NO: 41, residues 63-822 of SEQ ID NO: 51, residues 64-825 of SEQ ID NO: 61, residues 58-816 of SEQ ID NO: 71, residues 61-834 of SEQ ID NO: 81, residues 67-840 of SEQ ID NO: 91, residues 58-810 of SEQ ID NO: 101, a degenerate sequence thereof or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity thereto. In some examples, the nucleotide sequence encoding the beta chain contains one of the following: residues 58-930 of SEQ ID NO: 7, residues 58-936 of SEQ ID NO: 8, residues 58-933 of SEQ ID NO: 9 residues 58-939 of SEQ ID NO: 25, residues 64-930 of SEQ ID NO: 35, 45, or 95, residues 58-933 of SEQ ID NO: 54 or 85, residues 58-927 of SEQ ID NO: 65, residues 64-936 of SEQ ID NO: 75, residues 46-936 of SEQ ID NO: 105, a degenerate sequence thereof or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity thereto.

(368) In some embodiments, the nucleic acid molecule encoding an alpha chain and/or beta chain of a TCR comprises a nucleic acid sequence corresponding to a SEQ ID NO. set forth in Table 11. Also among the provided nucleic acid molecules encoding a TCR are those containing sequences at least at or about 90, 91, 92, 93, 94, 95, 96, 97, 98, or 99% identical to such sequences. Exemplary TCRs encoded by such sequences, or their modified versions, also are set forth in the Table 11.

(370) Also provided are vectors or constructs containing such nucleic acid molecules. In some embodiments, the vectors or constructs contain one or more promoters operatively linked to the nucleotide encoding the alpha chain and/or beta chain. In some embodiments, the promoter is operatively linked to one or more than one nucleic acid molecule.

(371) In some embodiments, the vector or construct can contain a single promoter that drives the expression of one or more nucleic acid molecules. In some embodiments, such promoters can be multicistronic (bicistronic or tricistronic, see e.g., U.S. Pat. No. 6,060,273). For example, in some embodiments, transcription units can be engineered as a bicistronic unit containing an IRES (internal ribosome entry site), which allows coexpression of gene products (e.g. encoding an alpha chain and/or beta chain of a TCR) by a message from a single promoter. Alternatively, in some cases, a single promoter may direct expression of an RNA that contains, in a single open reading frame (ORF), two or three genes (e.g. encoding an alpha chain and/or beta chain of a TCR) separated from one another by sequences encoding a self-cleavage peptide (e.g., T2A) or a protease recognition site (e.g., furin). The ORF thus encodes a single polyprotein, which, either during (in the case of 2A e.g., T2A) or after translation, is cleaved into the individual proteins. In some cases, the peptide, such as T2A, can cause the ribosome to skip (ribosome skipping) synthesis of a peptide bond at the C-terminus of a 2A element, leading to separation between the end of the 2A sequence and the next peptide downstream (see, for example, de Felipe. Genetic Vaccines and Ther. 2:13 (2004) and deFelipe et al. Traffic 5:616-626 (2004)). Examples of 2A cleavage peptides, including those that can induce ribosome skipping, are Thosea asigna virus (T2A, e.g., SEQ ID NO: 211 or 274), porcine teschovirus-1 (P2A, e.g., SEQ ID NO: 204 or 345), equine rhinitis A virus (E2A, e.g., SEQ ID NO: 346) and 2A sequences from the foot-and-mouth disease virus (F2A, e.g., SEQ ID NO: 344) as described in U.S. Patent Publication No. 2007/0116690.

(372) In some cases, the nucleotide sequence encoding the alpha chain and the nucleotide sequence encoding the beta chain are separated by a nucleotide sequence encoding an internal ribosome entry site (IRES) or a peptide sequence that causes ribosome skipping. In some instances, the nucleotide sequence encoding the alpha chain and the nucleotide sequence encoding the beta chain are separated by a peptide sequence that causes ribosome skipping. In some such instances, the peptide that causes ribosome skipping is a P2A or T2A peptide and/or contains the sequence of amino acids set forth in SEQ ID NO: 204, 211, 274 or 345. In some aspects, the nucleotide sequence encoding the peptide that causes ribosome skipping contains the sequence set forth in SEQ ID NO: 4, 5, 6, 207, 208, 209, or 210, 347, 1096, 1179, 1180, or 1181.

(373) In some embodiments, the nucleic acid sequence encoding the alpha chain and the nucleotide sequence encoding the beta chain are present in any order, separated by the nucleotide sequence encoding an internal ribosome entry site (IRES) or a peptide sequence that causes ribosome skipping. For example, in some embodiments, the nucleic acid molecule comprises a nucleic acid sequence encoding a beta chain, a nucleic acid sequence encoding an IRES or peptide sequence that causes ribosome skipping, e.g., a P2A or T2A sequence as described herein, and a nucleic acid sequence that encodes an alpha chain, in that order. In other embodiments, the nucleic acid molecule contains a nucleic acid sequence that encodes an alpha chain, a nucleic acid sequence that encodes an IRES or peptide sequence that causes ribosome skipping, and a nucleic acid sequence that encodes a beta chain, in that order.

(374) Thus, in some aspects, the nucleic acid molecule encodes a polypeptide comprising a beta chain, an IRES or peptide that causes ribosome skipping, and an alpha chain, in that order. In other aspects, the nucleic acid molecule encodes a polypeptide comprising an alpha chain, an IRES or peptide that causes ribosome skipping, and a beta chain, in that order.

(375) In some embodiments, the nucleic acid molecule encodes a polypeptide containing an amino acid sequence set forth in Table 12, or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% sequence identity thereto. In some embodiments, the nucleic acid molecule encodes a polypeptide set forth in any of SEQ ID NOS: 1, 2, 3, 27, 37, 47, 57, 67, 77, 87, 97, 107, 223, 224, 225, 226, 227, 228, 229, 230, 231, 340-342, 350-388, 391-429, or 1383-1384, or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% sequence identity thereto. In some embodiments, the nucleic acid molecule comprises the nucleic acid sequence set forth in any of SEQ ID NOs: 13, 14, 15, 26, 36, 46, 56, 66, 76, 86, 96, 106, 432-472, or 1382, or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% sequence identity thereto.

(376) Also provided are polypeptides containing a sequence encoded by any of the provided nucleic acids. In some aspects, the polypeptide comprises an amino acid sequence corresponding to a SEQ ID NO. shown in Table 12, or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% sequence identity thereto. In some embodiments, the polypeptide comprises the sequence set forth in any of SEQ ID NOS 1, 2, 3, 27, 37, 47, 57, 67, 77, 87, 97, 107, 223, 224, 225, 226, 227, 228, 229, 230, 231, 340-342, 350-388, or 391-429, or 1383-1384, or a sequence having at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% sequence identity thereto. Exemplary of such TCRs, or their modified versions, also are set forth in the Table 12.

(378) In some embodiments, the nucleic acid molecule may further encode a marker (e.g. EGFRt or other marker as described) that is separated from the CAR or separated from the TCR chains by a linker, such as a cleavable linker sequence or a peptide sequence that causes ribosome skipping, e.g., T2A or P2A.

(379) In some embodiments, the construct can be arranged in any order so that the encoding marker sequence is either 3 to the alpha and/or beta sequence, 5 to the alpha and/or beta sequence and/or between the alpha and beta sequence, where, in some cases, each separate component is separated by a cleavable linker sequence or a peptide that causes ribosome skipping (e.g. T2A or P2A) or an IRES. In some embodiments, the nucleic acid molecule contains a nucleic acid sequence that encodes a marker (e.g., EGFRt), cleavable linker or ribosome skip sequence (e.g. T2A or P2A), beta chain, cleavable linker or ribosome skip sequence (e.g. T2A or P2A), and alpha chain, in that order. In some embodiments, the nucleic acid molecule contains a nucleic acid sequence that encodes a marker (e.g., EGFRt), cleavable linker or ribosome skip sequence (e.g., T2A or P2A), alpha chain, cleavable linker or ribosome skip sequence (e.g., T2A or P2A), and beta chain, in that order. In some embodiments, the nucleic acid molecule contains a nucleic acid sequence that encodes a beta chain, cleavable linker or ribosome skip sequence (e.g., T2A or P2A), an alpha chain, a cleavable linker or ribosome skip sequence (e.g., T2A or P2A) and a marker (e.g. EGFRt), in that order. In some embodiments, the nucleic acid molecule contains a nucleic acid sequence that encodes an alpha chain, cleavable linker or ribosome skip sequence (e.g. T2A or P2A), a beta chain, a cleavable linker or ribosome skip sequence (e.g., T2A or P2A) and a marker (e.g., EGFRt), in that order. In some embodiments, the nucleic acid molecule contains a nucleic acid sequence that encodes an alpha chain, cleavable linker or ribosome skip sequence (e.g., T2A or P2A), a marker (e.g., EGFRt), a cleavable linker or ribosome skip sequence (e.g., T2A or P2A) and a beta chain, in that order. In some embodiments, the nucleic acid molecule contains a nucleic acid sequence that encodes a beta chain, cleavable linker or ribosome skip sequence (e.g., T2A or P2A), a marker (e.g. EGFRt), a cleavable linker or ribosome skip sequence (e.g., T2A or P2A) and a alpha chain, in that order.

(380) In some embodiments, introduction of a construct encoding the CAR and EGFRt separated by a T2A ribosome switch can express two proteins from the same construct, such that the EGFRt can be used as a marker to detect cells expressing such construct.

(381) The nucleic acid may encode an amino acid sequence comprising the variable alpha (V?) region or variable light (VL) region of the TCR or antibody, respectively. In some cases, the nucleic acid encodes an amino acid sequence comprising the variable beta (V?) region or variable heavy (VH) region of the TCR or antibody, respectively. In a further embodiment, one or more vectors (e.g., expression vectors) comprising such nucleic acid are provided.

(382) Also provided are vectors, such as those containing any of the nucleic acids described herein. In some embodiments, nucleic acid or nucleic acids encoding one or both chains of a binding molecule, e.g., TCR, are cloned into a suitable expression vector or vectors. The expression vector can be any suitable recombinant expression vector, and can be used to transform or transfect any suitable host. Suitable vectors include those designed for propagation and expansion or for expression or both, such as plasmids and viruses. In some embodiments, the vector is an expression vector.

(383) In some embodiments, the vector can a vector of the pUC series (Fermentas Life Sciences), the pBluescript series (Stratagene, LaJolla, Calif.), the pET series (Novagen, Madison, Wis.), the pGEX series (Pharmacia Biotech, Uppsala, Sweden), or the pEX series (Clontech, Palo Alto, Calif.). In some cases, bacteriophage vectors, such as ?G10, ?GT11, ?ZapII (Stratagene), ?EMBL4, and ?NM1149, also can be used. In some embodiments, plant expression vectors can be used and include pBI01, pBI101.2, pBI101.3, pBI121 and pBIN19 (Clontech). In some embodiments, animal expression vectors include pEUK-C1, pMAM and pMAMneo (Clontech). In some cases, the vector is a viral vector. In some such aspects, the viral vector is a retroviral vector, such as a lentiviral vector. In some instances, the lentiviral vector is derived from HIV-1.

(384) In some embodiments, the recombinant expression vectors can be prepared using standard recombinant DNA techniques. In some embodiments, vectors can contain regulatory sequences, such as transcription and translation initiation and termination codons, which are specific to the type of host (e.g., bacterium, fungus, plant, or animal) into which the vector is to be introduced, as appropriate and taking into consideration whether the vector is DNA- or RNA-based. In some embodiments, the vector can contain a nonnative promoter operably linked to the nucleotide sequence encoding the binding molecule, such as TCR, antibody or antigen-binding fragment thereof. In some embodiments, the promoter can be a non-viral promoter or a viral promoter, such as a cytomegalovirus (CMV) promoter, an SV40 promoter, an RSV promoter, and a promoter found in the long-terminal repeat of the murine stem cell virus. Other promoters known to a skilled artisan also are contemplated.

(385) Also provided are methods of making the binding molecules (including antigen-binding fragments). In some embodiments, a host cell comprising such nucleic acid is provided. For recombinant production of the binding molecules, nucleic acid encoding the binding molecule, e.g., as described above, may be isolated and inserted into one or more vectors for further cloning and/or expression in a host cell. Such nucleic acid may be readily isolated and sequenced using conventional procedures (e.g., by using oligonucleotide probes that are capable of binding specifically to genes encoding the alpha and beta chains of the TCR or the heavy and light chains of the antibody). In some embodiments, a method of making the binding molecule is provided, wherein the method comprises culturing a host cell comprising a nucleic acid encoding the binding molecule, as provided above, under conditions suitable for expression of the binding molecule, and optionally recovering the binding molecule from the host cell (or host cell culture medium).

(386) In one such embodiment, a host cell comprises (e.g., has been transformed with): a vector comprising a nucleic acid that encodes an amino acid sequence comprising the V? region of the TCR or antigen-binding fragment thereof and a nucleic acid that encodes an amino acid sequence comprising the V? region of the TCR or antigen-binding fragment thereof. In another such embodiment, a host cell comprises (e.g. has been transformed with): a vector comprising a nucleic acid that encodes an amino acid sequence comprising the V.sub.H of the antibody or antigen-binding fragment thereof and the V.sub.L of the antibody or antigen-binding fragment thereof. In some aspects, a host cell comprises (e.g., has been transformed with): a first vector comprising a nucleic acid that encodes an amino acid sequence comprising the V? region of the TCR or antigen-binding fragment thereof and a second vector comprising a nucleic acid that encodes an amino acid sequence comprising the V? region of the TCR or antigen-binding fragment thereof. In other aspects, a host cell comprises (e.g. has been transformed with): a first vector comprising a nucleic acid that encodes an amino acid sequence or comprising the V.sub.L of the antibody or antigen-binding fragment thereof and a second vector comprising a nucleic acid that encodes an amino acid sequence comprising the V.sub.H of the antibody or antigen-binding fragment thereof.

(387) In addition to prokaryotes, eukaryotic microbes such as filamentous fungi or yeast are suitable cloning or expression hosts for binding molecule-encoding vectors, including fungi and yeast strains whose glycosylation pathways have been modified to mimic or approximate those in human cells. See Gerngross, Nat. Biotech. 22:1409-1414 (2004), and Li et al., Nat. Biotech. 24:210-215 (2006).

(388) Exemplary eukaryotic cells that may be used to express polypeptides include, but are not limited to, COS cells, including COS 7 cells; 293 cells, including 293-6E cells; CHO cells, including CHO-S, DG44. Lec13 CHO cells, and FUT8 CHO cells; PER.C6? cells; and NSO cells. In some embodiments, a particular eukaryotic host cell is selected based on its ability to make desired post-translational modifications to the binding molecule. For example, in some embodiments, CHO cells produce polypeptides that have a higher level of sialylation than the same polypeptide produced in 293 cells. In some embodiments, the binding molecule is produced in a cell-free system. Exemplary cell-free systems are described, e.g., in Sitaraman et al., Methods Mol. Biol. 498: 229-44 (2009); Spirin, Trends Biotechnol. 22: 538-45 (2004); Endo et al., Biotechnol. Adv. 21: 695-713 (2003).

III. Methods for Identifying and Generating T Cell Receptors

(389) In some embodiments, provided are methods for identifying and generating T cell receptors directed towards a target antigen. In some aspects, the methods involve subjecting biological samples containing T cells, such as primary T cells, including those derived from normal donors or patients having a disease or condition of interest, to multiple rounds of antigen exposure and assessment. In some aspects, the rounds involve the use of artificial or engineered antigen presenting cells, such as autologous dendritic cells or other APCs pulsed with a desired peptide antigen, to promote presentation on an MHC, such as a class I or II MHC. In some aspects, multiple rounds of antigen exposure are carried out and in some aspects T cells are sorted following one or more of the rounds, e.g., based on ability to bind to the desired antigen (such as peptide-MHC tetramers). In some aspects sorting is carried out by flow cytometry. In some aspects, cells from cells deemed to bind to the desired antigen (positive fraction) and cells deemed not to bind to the antigen, are assessed, e.g., by single-cell sequencing methods. In some aspects, the methods sequence and identify, at a single-cell level, TCR pairs present in each sample. In some aspects, the methods can quantify the number of copies of a given TCR pair present in a sample, and as such can assess the abundance of a given TCR in a given sample, and/or enrichment thereof over another sample, such as enrichment or abundance in the positive (antigen-binding) fraction, e.g., over one or more rounds, for example, as compared to the negative fraction. In some aspects, such assays are performed to generate antigen-specific T cell receptors (TCRs) that specifically bind to human papillomavirus 16 or 18 peptide antigens such as peptides derived from E6 or E7, such as E6(29-38) or E7(11-19) peptide, e.g., presented on MHC-I molecules and survived and/or were enriched over time, following multiple rounds of antigen-stimulation. In some aspects, clonal T cell lines are generated and the sequences of individual paired TCR alpha and beta chains and abundance thereof in various populations were determined on a single-cell basis, using high-throughput paired TCR sequencing.

(390) In some aspects, peptide-pulsed HLA:A02:01APCs were generated with HPV 16 E6(29-38) peptide (TIHDIILECV; SEQ ID NO:233) or E7(11-19) peptide (YMLDLQPET; SEQ ID NO:236). Autologous CD8+ T cells from normal human donors are incubated over multiple rounds with the peptide-pulsed cells, and selections were carried out based on binding to peptide-loaded autologous MHC tetramers.

(391) In some aspects, cells were subjected to multiple, such as a total of two or three or more, rounds of stimulation, in the presence of peptide-pulsed cells (such as with a particular peptide concentration of 1000 ng/mL maintained over the three rounds). Following one or more of, such as following the first and/or following the second and third rounds of stimulation, cells were sorted by flow cytometry into populations positive and negative, respectively, for binding to peptide-MHC tetramers containing the appropriate tetramer. Cells of the tetramer-positive and negative populations following each or one or more of the one or more, such as the second and third, rounds in some aspects are subjected to single-cell TCR sequencing, to assess the presence and frequency of individual TCRs in the different populations, and the persistence of TCR clones over multiple rounds of antigen stimulation.

(392) In some aspects, cell populations from the positive and negative fractions (i.e., sorted by flow cytometry based on positive and negative staining, respectively, for binding to the relevant antigen such as peptide-MHC such as loaded tetramers, e.g., as determined by flow cytometry), following the one or more rounds, are subject to high-throughput single-cell sequencing for TCR alpha and beta chain pairs. High throughput single cell TCR sequencing in some aspects is performed as generally described in published PCT patent applications, publication numbers WO2012/048340, WO2012/048341 and WO2016/044227. The sequencing methods thus in some aspects employ single-cell droplets and sample and molecular barcodes, to identify individual pairs of TCR alpha and beta chain sequences at a single-cell level, for each of a large number (e.g., millions) of single cells present in a single starting composition, and to assess abundance of each TCR pair in various populations assessed. The ability to identify and quantify TCR pairs at a single-cell level in some embodiments permits the assessment of the frequency of each of various TCR pairs in each of the individual positive and negative fractions, and to assess enrichment and persistence of TCRs over multiple rounds of antigen stimulation.

(393) In some aspects, the methods generate, identify, isolate and/or select TCR pairs that are enriched in antigen-binding, e.g., peptide-binding, fractions following at least one and in some aspects a plurality of, multiple rounds of stimulation. In some aspects, the TCRs are present in and/or present at a desired abundance in and/or preferentially enriched following, rounds 1, 2 and/or and 3 and in some aspects at least multiple rounds, of antigen exposure. In some aspects, the TCRs are enriched in the population over time following multiple rounds of exposure to antigen. Also provided are TCRs generated or identified using such methods, such as TCRs having such properties, such as the ability to survive and/or expand over multiple rounds of antigen exposure, such as in a peptide-pulsed APC assay.

IV. Engineered Cells

(394) Also provided are cells such as cells that have been engineered to contain the binding molecule described herein. Also provided are populations of such cells, compositions containing such cells and/or enriched for such cells, such as in which cells expressing the binding molecule make up at least 15%, 20%, 25%, 30%, 35%, 40%, 50%, 60%, 70%, 80%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or more percent of the total cells in the composition or cells of a certain type such as T cells or CD8+ or CD4+ cells. In some embodiments, the cells are primary T cells. Among the compositions are pharmaceutical compositions and formulations for administration, such as for adoptive cell therapy. Also provided are therapeutic methods for administering the cells and compositions to subjects, e.g., patients.

(395) Thus also provided are genetically engineered cells expressing the binding molecules. The cells generally are eukaryotic cells, such as mammalian cells, and typically are human cells. In some embodiments, the cells are derived from the blood, bone marrow, lymph, or lymphoid organs, are cells of the immune system, such as cells of the innate or adaptive immunity, e.g., myeloid or lymphoid cells, including lymphocytes, typically T cells and/or NK cells. Other exemplary cells include stem cells, such as multipotent and pluripotent stem cells, including induced pluripotent stem cells (iPSCs). The cells typically are primary cells, such as those isolated directly from a subject and/or isolated from a subject and frozen. In some embodiments, the cells include one or more subsets of T cells or other cell types, such as whole T cell populations, CD4+ cells, CD8+ cells, and subpopulations thereof, such as those defined by function, activation state, maturity, potential for differentiation, expansion, recirculation, localization, and/or persistence capacities, antigen-specificity, type of antigen receptor, presence in a particular organ or compartment, marker or cytokine secretion profile, and/or degree of differentiation. With reference to the subject to be treated, the cells may be allogeneic and/or autologous. Among the methods include off-the-shelf methods. In some aspects, such as for off-the-shelf technologies, the cells are pluripotent and/or multipotent, such as stem cells, such as induced pluripotent stem cells (iPSCs). In some embodiments, the methods include isolating cells from the subject, preparing, processing, culturing, and/or engineering them, as described herein, and re-introducing them into the same patient, before or after cryopreservation.

(396) Among the sub-types and subpopulations of T cells and/or of CD4+ and/or of CD8+ T cells are na?ve T (T.sub.N) cells, effector T cells (T.sub.EFF), memory T cells and sub-types thereof, such as stem cell memory T (T.sub.SCM), central memory T (T.sub.CM), effector memory T (T.sub.EM), or terminally differentiated effector memory T cells, tumor-infiltrating lymphocytes (TIL), immature T cells, mature T cells, helper T cells, cytotoxic T cells, mucosa-associated invariant T (MAIT) cells, naturally occurring and adaptive regulatory T (Treg) cells, helper T cells, such as TH1 cells, TH2 cells, TH3 cells, TH17 cells, TH9 cells, TH22 cells, follicular helper T cells, alpha/beta T cells, and delta/gamma T cells.

(397) In some embodiments, the cells are natural killer (NK) cells. In some embodiments, the cells are monocytes or granulocytes, e.g., myeloid cells, macrophages, neutrophils, dendritic cells, mast cells, eosinophils, and/or basophils.

(398) In some embodiments, the cells include one or more nucleic acids introduced via genetic engineering, and thereby express recombinant or genetically engineered products of such nucleic acids. In some embodiments, the nucleic acids are heterologous, i.e., normally not present in a cell or sample obtained from the cell, such as one obtained from another organism or cell, which for example, is not ordinarily found in the cell being engineered and/or an organism from which such cell is derived. In some embodiments, the nucleic acids are not naturally occurring, such as a nucleic acid not found in nature, including one comprising chimeric combinations of nucleic acids encoding various domains from multiple different cell types.

(399) In some embodiments, genes and/or gene products (and/or expression thereof) in the provided cells, and/or compositions containing such cells, are reduced, deleted, eliminated, knocked-out or disrupted. Such genes and/or gene products in some aspects include one or more of the gene encoding (or product thereof) TCR alpha constant region (TRAC) and/or TCR beta constant region (TRBC; encoded in humans by TRBC1 or TRBC2), e.g., to reduce or prevent expression of the endogenous TCR in the cell, e.g. T cell, and/or ? chain thereof. In some embodiments, the genes and/or gene products, such as TRAC and/or TRBC, is reduced, deleted, eliminated, knocked-out or disrupted in any of the engineered cells provided herein and/or in any of the methods for producing engineered cells provided herein. In some embodiments, engineered cells and/or engineered cells produced by the methods are cells that have been engineered to express the binding molecule described herein, populations of such cells, compositions containing such cells and/or enriched for such cells. In some embodiments, genes and/or gene products, such as the TRAC and/or TRBC, is reduced, deleted, eliminated, knocked-out or disrupted in primary T cells, to reduce, delete, eliminate, knock-out or disrupt the expression of the endogenous TCR in primary T cells, e.g., that are engineered to express any of the binding molecules, e.g., TCRs, described herein.

(400) In some embodiments, the reduction, deletion, elimination, knock-out or disruption of the endogenous genes encoding the TCR or ? chain, a domain and/or a region thereof is carried out, e.g., by any methods or processes described herein, e.g., in Section V below.

(401) A. Preparation of Cells for Genetic Engineering

(402) In some embodiments, preparation of the engineered cells includes one or more culture and/or preparation steps. The cells for introduction of the binding molecule, e.g., TCR or CAR, may be isolated from a sample, such as a biological sample, e.g., one obtained from or derived from a subject. In some embodiments, the subject from which the cell is isolated is one having the disease or condition or in need of a cell therapy or to which cell therapy will be administered. The subject in some embodiments is a human in need of a particular therapeutic intervention, such as the adoptive cell therapy for which cells are being isolated, processed, and/or engineered.

(403) Accordingly, the cells in some embodiments are primary cells, e.g., primary human cells. The samples include tissue, fluid, and other samples taken directly from the subject, as well as samples resulting from one or more processing steps, such as separation, centrifugation, genetic engineering (e.g. transduction with viral vector), washing, and/or incubation. The biological sample can be a sample obtained directly from a biological source or a sample that is processed. Biological samples include, but are not limited to, body fluids, such as blood, plasma, serum, cerebrospinal fluid, synovial fluid, urine and sweat, tissue and organ samples, including processed samples derived therefrom.

(404) In some aspects, the sample from which the cells are derived or isolated is blood or a blood-derived sample, or is or is derived from an apheresis or leukapheresis product. Exemplary samples include whole blood, peripheral blood mononuclear cells (PBMCs), leukocytes, bone marrow, thymus, tissue biopsy, tumor, leukemia, lymphoma, lymph node, gut associated lymphoid tissue, mucosa associated lymphoid tissue, spleen, other lymphoid tissues, liver, lung, stomach, intestine, colon, kidney, pancreas, breast, bone, prostate, cervix, testes, ovaries, tonsil, or other organ, and/or cells derived therefrom. Samples include, in the context of cell therapy, e.g., adoptive cell therapy, samples from autologous and allogeneic sources.

(405) In some embodiments, the cells are derived from cell lines, e.g., T cell lines. The cells in some embodiments are obtained from a xenogeneic source, for example, from mouse, rat, non-human primate, or pig.

(406) In some embodiments, isolation of the cells includes one or more preparation and/or non-affinity based cell separation steps. In some examples, cells are washed, centrifuged, and/or incubated in the presence of one or more reagents, for example, to remove unwanted components, enrich for desired components, lyse or remove cells sensitive to particular reagents. In some examples, cells are separated based on one or more property, such as density, adherent properties, size, sensitivity and/or resistance to particular components.

(407) In some examples, cells from the circulating blood of a subject are obtained, e.g., by apheresis or leukapheresis. The samples, in some aspects, contain lymphocytes, including T cells, monocytes, granulocytes, B cells, other nucleated white blood cells, red blood cells, and/or platelets, and in some aspects contain cells other than red blood cells and platelets.

(408) In some embodiments, the blood cells collected from the subject are washed, e.g., to remove the plasma fraction and to place the cells in an appropriate buffer or media for subsequent processing steps. In some embodiments, the cells are washed with phosphate buffered saline (PBS). In some embodiments, the wash solution lacks calcium and/or magnesium and/or many or all divalent cations. In some aspects, a washing step is accomplished a semi-automated flow-through centrifuge (for example, the Cobe 2991 cell processor, Baxter) according to the manufacturer's instructions. In some aspects, a washing step is accomplished by tangential flow filtration (TFF) according to the manufacturer's instructions. In some embodiments, the cells are resuspended in a variety of biocompatible buffers after washing, such as, for example, Ca.sup.++/Mg.sup.++ free PBS. In certain embodiments, components of a blood cell sample are removed and the cells directly resuspended in culture media.

(409) In some embodiments, the methods include density-based cell separation methods, such as the preparation of white blood cells from peripheral blood by lysing the red blood cells and centrifugation through a Percoll or Ficoll gradient.

(410) In some embodiments, the isolation methods include the separation of different cell types based on the expression or presence in the cell of one or more specific molecules, such as surface markers, e.g., surface proteins, intracellular markers, or nucleic acid. In some embodiments, any known method for separation based on such markers may be used. In some embodiments, the separation is affinity- or immunoaffinity-based separation. For example, the isolation in some aspects includes separation of cells and cell populations based on the cells' expression or expression level of one or more markers, typically cell surface markers, for example, by incubation with an antibody or binding partner that specifically binds to such markers, followed generally by washing steps and separation of cells having bound the antibody or binding partner, from those cells having not bound to the antibody or binding partner.

(411) Such separation steps can be based on positive selection, in which the cells having bound the reagents are retained for further use, and/or negative selection, in which the cells having not bound to the antibody or binding partner are retained. In some examples, both fractions are retained for further use. In some aspects, negative selection can be particularly useful where no antibody is available that specifically identifies a cell type in a heterogeneous population, such that separation is best carried out based on markers expressed by cells other than the desired population.

(412) The separation need not result in 100% enrichment or removal of a particular cell population or cells expressing a particular marker. For example, positive selection of or enrichment for cells of a particular type, such as those expressing a marker, refers to increasing the number or percentage of such cells, but need not result in a complete absence of cells not expressing the marker. Likewise, negative selection, removal, or depletion of cells of a particular type, such as those expressing a marker, refers to decreasing the number or percentage of such cells, but need not result in a complete removal of all such cells.

(413) In some examples, multiple rounds of separation steps are carried out, where the positively or negatively selected fraction from one step is subjected to another separation step, such as a subsequent positive or negative selection. In some examples, a single separation step can deplete cells expressing multiple markers simultaneously, such as by incubating cells with a plurality of antibodies or binding partners, each specific for a marker targeted for negative selection. Likewise, multiple cell types can simultaneously be positively selected by incubating cells with a plurality of antibodies or binding partners expressed on the various cell types.

(414) For example, in some aspects, specific subpopulations of T cells, such as cells positive or expressing high levels of one or more surface markers, e.g., CD28.sup.+, CD62L.sup.+, CCR7.sup.+, CD27.sup.+, CD127.sup.+, CD4.sup.+, CD8.sup.+, CD45RA.sup.+, and/or CD45RO.sup.+ T cells, are isolated by positive or negative selection techniques.

(415) For example, CD3+, CD28.sup.+ T cells can be positively selected using anti-CD3/anti-CD28 conjugated magnetic beads (e.g., DYNABEADS? M-450 CD3/CD28 T Cell Expander).

(416) In some embodiments, isolation is carried out by enrichment for a particular cell population by positive selection, or depletion of a particular cell population, by negative selection. In some embodiments, positive or negative selection is accomplished by incubating cells with one or more antibodies or other binding agent that specifically bind to one or more surface markers expressed or expressed (marker.sup.+) at a relatively higher level (marker.sup.high) on the positively or negatively selected cells, respectively.

(417) In some embodiments, T cells are separated from a PBMC sample by negative selection of markers expressed on non-T cells, such as B cells, monocytes, or other white blood cells, such as CD14. In some aspects, a CD4.sup.+ or CD8.sup.+ selection step is used to separate CD4.sup.+ helper and CD8.sup.+ cytotoxic T cells. Such CD4.sup.+ and CD8.sup.+ populations can be further sorted into sub-populations by positive or negative selection for markers expressed or expressed to a relatively higher degree on one or more naive, memory, and/or effector T cell subpopulations.

(418) In some embodiments, CD8+ cells are further enriched for or depleted of naive, central memory, effector memory, and/or central memory stem cells, such as by positive or negative selection based on surface antigens associated with the respective subpopulation. In some embodiments, enrichment for central memory T (T.sup.CM) cells is carried out to increase efficacy, such as to improve long-term survival, expansion, and/or engraftment following administration, which in some aspects is particularly robust in such sub-populations. See Terakura et al. (2012) Blood. 1:72-82; Wang et al. (2012) J Immunother. 35(9):689-701. In some embodiments, combining T.sub.CM-enriched CD8+ T cells and CD4.sup.+ T cells further enhances efficacy.

(419) In embodiments, memory T cells are present in both CD62L.sup.+ and CD62L.sup.? subsets of CD8.sup.+ peripheral blood lymphocytes. PBMC can be enriched for or depleted of CD62L.sup.?CD8.sup.+ and/or CD62L.sup.+ CD8.sup.+ fractions, such as using anti-CD8 and anti-CD62L antibodies.

(420) In some embodiments, the enrichment for central memory T (T.sub.CM) cells is based on positive or high surface expression of CD45RO, CD62L, CCR7, CD28, CD3, and/or CD 127; in some aspects, it is based on negative selection for cells expressing or highly expressing CD45RA and/or granzyme B. In some aspects, isolation of a CD8.sup.+ population enriched for T.sub.CM cells is carried out by depletion of cells expressing CD4, CD14, CD45RA, and positive selection or enrichment for cells expressing CD62L. In one aspect, enrichment for central memory T (T.sub.CM) cells is carried out starting with a negative fraction of cells selected based on CD4 expression, which is subjected to a negative selection based on expression of CD14 and CD45RA, and a positive selection based on CD62L. Such selections in some aspects are carried out simultaneously and in other aspects are carried out sequentially, in either order. In some aspects, the same CD4 expression-based selection step used in preparing the CD8.sup.+ cell population or subpopulation, also is used to generate the CD4.sup.+ cell population or sub-population, such that both the positive and negative fractions from the CD4-based separation are retained and used in subsequent steps of the methods, optionally following one or more further positive or negative selection steps.

(421) In a particular example, a sample of PBMCs or other white blood cell sample is subjected to selection of CD4.sup.+ cells, where both the negative and positive fractions are retained. The negative fraction then is subjected to negative selection based on expression of CD14 and CD45RA, and positive selection based on a marker characteristic of central memory T cells, such as CD62L or CCR7, where the positive and negative selections are carried out in either order.

(422) CD4+ T helper cells are sorted into na?ve, central memory, and effector cells by identifying cell populations that have cell surface antigens. CD4.sup.+ lymphocytes can be obtained by standard methods. In some embodiments, naive CD4.sup.+ T lymphocytes are CD45RO.sup.?, CD45RA.sup.+, CD62L.sup.+, CD4.sup.+ T cells. In some embodiments, central memory CD4.sup.+ cells are CD62L.sup.+ and CD45RO.sup.+. In some embodiments, effector CD4.sup.+ cells are CD62L.sup.? and CD45RO.sup.?.

(423) In one example, to enrich for CD4.sup.+ cells by negative selection, a monoclonal antibody cocktail typically includes antibodies to CD14, CD20, CD11b, CD16, HLA-DR, and CD8. In some embodiments, the antibody or binding partner is bound to a solid support or matrix, such as a magnetic bead or paramagnetic bead, to allow for separation of cells for positive and/or negative selection. For example, in some embodiments, the cells and cell populations are separated or isolated using immunomagnetic (or affinity magnetic) separation techniques (reviewed in Methods in Molecular Medicine, vol. 58: Metastasis Research Protocols, Vol. 2: Cell Behavior In Vitro and In Vivo, p 17-25 Edited by: S. A. Brooks and U. Schumacher? Humana Press Inc., Totowa, N.J.).

(424) In some aspects, the sample or composition of cells to be separated is incubated with small, magnetizable or magnetically responsive material, such as magnetically responsive particles or microparticles, such as paramagnetic beads (e.g., such as Dynabeads or MACS beads). The magnetically responsive material, e.g., particle, generally is directly or indirectly attached to a binding partner, e.g., an antibody, that specifically binds to a molecule, e.g., surface marker, present on the cell, cells, or population of cells that it is desired to separate, e.g., that it is desired to negatively or positively select.

(425) In some embodiments, the magnetic particle or bead comprises a magnetically responsive material bound to a specific binding member, such as an antibody or other binding partner. There are many well-known magnetically responsive materials used in magnetic separation methods. Suitable magnetic particles include those described in Molday, U.S. Pat. No. 4,452,773, and in European Patent Specification EP 452342 B, which are hereby incorporated by reference. Colloidal sized particles, such as those described in Owen U.S. Pat. No. 4,795,698, and Liberti et al., U.S. Pat. No. 5,200,084 are other examples.

(426) The incubation generally is carried out under conditions whereby the antibodies or binding partners, or molecules, such as secondary antibodies or other reagents, which specifically bind to such antibodies or binding partners, which are attached to the magnetic particle or bead, specifically bind to cell surface molecules if present on cells within the sample.

(427) In some aspects, the sample is placed in a magnetic field, and those cells having magnetically responsive or magnetizable particles attached thereto will be attracted to the magnet and separated from the unlabeled cells. For positive selection, cells that are attracted to the magnet are retained; for negative selection, cells that are not attracted (unlabeled cells) are retained. In some aspects, a combination of positive and negative selection is performed during the same selection step, where the positive and negative fractions are retained and further processed or subject to further separation steps.

(428) In certain embodiments, the magnetically responsive particles are coated in primary antibodies or other binding partners, secondary antibodies, lectins, enzymes, or streptavidin. In certain embodiments, the magnetic particles are attached to cells via a coating of primary antibodies specific for one or more markers. In certain embodiments, the cells, rather than the beads, are labeled with a primary antibody or binding partner, and then cell-type specific secondary antibody- or other binding partner (e.g., streptavidin)-coated magnetic particles, are added. In certain embodiments, streptavidin-coated magnetic particles are used in conjunction with biotinylated primary or secondary antibodies.

(429) In some embodiments, the magnetically responsive particles are left attached to the cells that are to be subsequently incubated, cultured and/or engineered; in some aspects, the particles are left attached to the cells for administration to a patient. In some embodiments, the magnetizable or magnetically responsive particles are removed from the cells. Methods for removing magnetizable particles from cells are known and include, e.g., the use of competing non-labeled antibodies, magnetizable particles or antibodies conjugated to cleavable linkers, etc. In some embodiments, the magnetizable particles are biodegradable.

(430) In some embodiments, the affinity-based selection is via magnetic-activated cell sorting (MACS) (Miltenyi Biotec, Auburn, Calif.). Magnetic Activated Cell Sorting (MACS) systems are capable of high-purity selection of cells having magnetized particles attached thereto. In certain embodiments, MACS operates in a mode wherein the non-target and target species are sequentially eluted after the application of the external magnetic field. That is, the cells attached to magnetized particles are held in place while the unattached species are eluted. Then, after this first elution step is completed, the species that were trapped in the magnetic field and were prevented from being eluted are freed in some manner such that they can be eluted and recovered. In certain embodiments, the non-target cells are labelled and depleted from the heterogeneous population of cells.

(431) In certain embodiments, the isolation or separation is carried out using a system, device, or apparatus that carries out one or more of the isolation, cell preparation, separation, processing, incubation, culture, and/or formulation steps of the methods. In some aspects, the system is used to carry out each of these steps in a closed or sterile environment, for example, to minimize error, user handling and/or contamination. In one example, the system is a system as described in International Patent Application, Publication Number WO2009/072003, or US 2011/0003380 A1.

(432) In some embodiments, the system or apparatus carries out one or more, e.g., all, of the isolation, processing, engineering, and formulation steps in an integrated or self-contained system, and/or in an automated or programmable fashion. In some aspects, the system or apparatus includes a computer and/or computer program in communication with the system or apparatus, which allows a user to program, control, assess the outcome of, and/or adjust various aspects of the processing, isolation, engineering, and formulation steps.

(433) In some aspects, the separation and/or other steps is carried out using CliniMACS system (Miltenyi Biotec), for example, for automated separation of cells on a clinical-scale level in a closed and sterile system. Components can include an integrated microcomputer, magnetic separation unit, peristaltic pump, and various pinch valves. The integrated computer in some aspects controls all components of the instrument and directs the system to perform repeated procedures in a standardized sequence. The magnetic separation unit in some aspects includes a movable permanent magnet and a holder for the selection column. The peristaltic pump controls the flow rate throughout the tubing set and, together with the pinch valves, ensures the controlled flow of buffer through the system and continual suspension of cells.

(434) The CliniMACS system in some aspects uses antibody-coupled magnetizable particles that are supplied in a sterile, non-pyrogenic solution. In some embodiments, after labelling of cells with magnetic particles the cells are washed to remove excess particles. A cell preparation bag is then connected to the tubing set, which in turn is connected to a bag containing buffer and a cell collection bag. The tubing set consists of pre-assembled sterile tubing, including a pre-column and a separation column, and are for single use only. After initiation of the separation program, the system automatically applies the cell sample onto the separation column. Labelled cells are retained within the column, while unlabeled cells are removed by a series of washing steps. In some embodiments, the cell populations for use with the methods described herein are unlabeled and are not retained in the column. In some embodiments, the cell populations for use with the methods described herein are labeled and are retained in the column. In some embodiments, the cell populations for use with the methods described herein are eluted from the column after removal of the magnetic field, and are collected within the cell collection bag.

(435) In certain embodiments, separation and/or other steps are carried out using the CliniMACS Prodigy system (Miltenyi Biotec). The CliniMACS Prodigy system in some aspects is equipped with a cell processing unity that permits automated washing and fractionation of cells by centrifugation. The CliniMACS Prodigy system can also include an onboard camera and image recognition software that determines the optimal cell fractionation endpoint by discerning the macroscopic layers of the source cell product. For example, peripheral blood may be automatically separated into erythrocytes, white blood cells and plasma layers. The CliniMACS Prodigy system can also include an integrated cell cultivation chamber which accomplishes cell culture protocols such as, e.g., cell differentiation and expansion, antigen loading, and long-term cell culture. Input ports can allow for the sterile removal and replenishment of media and cells can be monitored using an integrated microscope. See, e.g., Klebanoff et al. (2012) J Immunother. 35(9): 651-660, Terakura et al. (2012) Blood. 1:72-82, and Wang et al. (2012) J Immunother. 35(9):689-701.

(436) In some embodiments, a cell population described herein is collected and enriched (or depleted) via flow cytometry, in which cells stained for multiple cell surface markers are carried in a fluidic stream. In some embodiments, a cell population described herein is collected and enriched (or depleted) via preparative scale (FACS)-sorting. In certain embodiments, a cell population described herein is collected and enriched (or depleted) by use of microelectromechanical systems (MEMS) chips in combination with a FACS-based detection system (see, e.g., WO 2010/033140, Cho et al. (2010) Lab Chip 10, 1567-1573; and Godin et al. (2008) J Biophoton. 1(5):355-376. In both cases, cells can be labeled with multiple markers, allowing for the isolation of well-defined T cell subsets at high purity.

(437) In some embodiments, the antibodies or binding partners are labeled with one or more detectable marker, to facilitate separation for positive and/or negative selection. For example, separation may be based on binding to fluorescently labeled antibodies. In some examples, separation of cells based on binding of antibodies or other binding partners specific for one or more cell surface markers are carried in a fluidic stream, such as by fluorescence-activated cell sorting (FACS), including preparative scale (FACS) and/or microelectromechanical systems (MEMS) chips, e.g., in combination with a flow-cytometric detection system. Such methods allow for positive and negative selection based on multiple markers simultaneously.

(438) In some embodiments, the preparation methods include steps for freezing, e.g., cryopreserving, the cells, either before or after isolation, incubation, and/or engineering. In some embodiments, the freeze and subsequent thaw step removes granulocytes and, to some extent, monocytes in the cell population. In some embodiments, the cells are suspended in a freezing solution, e.g., following a washing step to remove plasma and platelets. Any of a variety of known freezing solutions and parameters in some aspects may be used. One example involves using PBS containing 20% DMSO and 8% human serum albumin (HSA), or other suitable cell freezing media. This is then diluted 1:1 with media so that the final concentration of DMSO and HSA are 10% and 4%, respectively. The cells are then frozen to ?80? C. at a rate of 1? per minute and stored in the vapor phase of a liquid nitrogen storage tank.

(439) In some embodiments, the provided methods include cultivation, incubation, culture, and/or genetic engineering steps. For example, in some embodiments, provided are methods for incubating and/or engineering the depleted cell populations and culture-initiating compositions.

(440) Thus, in some embodiments, the cell populations are incubated in a culture-initiating composition. The incubation and/or engineering may be carried out in a culture vessel, such as a unit, chamber, well, column, tube, tubing set, valve, vial, culture dish, bag, or other container for culture or cultivating cells.

(441) In some embodiments, the cells are incubated and/or cultured prior to or in connection with genetic engineering. The incubation steps can include culture, cultivation, stimulation, activation, and/or propagation. In some embodiments, the compositions or cells are incubated in the presence of stimulating conditions or a stimulatory agent. Such conditions include those designed to induce proliferation, expansion, activation, and/or survival of cells in the population, to mimic antigen exposure, and/or to prime the cells for genetic engineering, such as for the introduction of an antigen receptor.

(442) The conditions can include one or more of particular media, temperature, oxygen content, carbon dioxide content, time, agents, e.g., nutrients, amino acids, antibiotics, ions, and/or stimulatory factors, such as cytokines, chemokines, antigens, binding partners, fusion proteins, recombinant soluble receptors, and any other agents designed to activate the cells.

(443) In some embodiments, the stimulating conditions or agents include one or more agent, e.g., ligand, which is capable of activating an intracellular signaling domain of a TCR complex. In some aspects, the agent turns on or initiates TCR/CD3 intracellular signaling cascade in a T cell. Such agents can include antibodies, such as those specific for a TCR component and/or costimulatory receptor, e.g., anti-CD3. In some embodiments, the stimulating conditions include one or more agent, e.g. ligand, which is capable of stimulating a costimulatory receptor, e.g., anti-CD28. In some embodiments, such agents and/or ligands may be, bound to solid support such as a bead, and/or one or more cytokines. Optionally, the expansion method may further comprise the step of adding anti-CD3 and/or anti CD28 antibody to the culture medium (e.g., at a concentration of at least about 0.5 ng/ml). In some embodiments, the stimulating agents include IL-2, IL-15 and/or IL-7. In some aspects, the IL-2 concentration is at least about 10 units/mL.

(444) In some aspects, incubation is carried out in accordance with techniques such as those described in U.S. Pat. No. 6,040,177 to Riddell et al., Klebanoff et al. (2012) J Immunother. 35(9): 651-660, Terakura et al. (2012) Blood. 1:72-82, and/or Wang et al. (2012) J Immunother. 35(9):689-701.

(445) In some embodiments, the T cells are expanded by adding to the culture-initiating composition feeder cells, such as non-dividing peripheral blood mononuclear cells (PBMC), (e.g., such that the resulting population of cells contains at least about 5, 10, 20, or 40 or more PBMC feeder cells for each T lymphocyte in the initial population to be expanded); and incubating the culture (e.g. for a time sufficient to expand the numbers of T cells). In some aspects, the non-dividing feeder cells can comprise gamma-irradiated PBMC feeder cells. In some embodiments, the PBMC are irradiated with gamma rays in the range of about 3000 to 3600 rads to prevent cell division. In some aspects, the feeder cells are added to culture medium prior to the addition of the populations of T cells.

(446) In some embodiments, the stimulating conditions include temperature suitable for the growth of human T lymphocytes, for example, at least about 25 degrees Celsius, generally at least about 30 degrees, and generally at or about 37 degrees Celsius. Optionally, the incubation may further comprise adding non-dividing EBV-transformed lymphoblastoid cells (LCL) as feeder cells. LCL can be irradiated with gamma rays in the range of about 6000 to 10,000 rads. The LCL feeder cells in some aspects is provided in any suitable amount, such as a ratio of LCL feeder cells to initial T lymphocytes of at least about 10:1.

(447) In embodiments, antigen-specific T cells, such as antigen-specific CD4+ and/or CD8+ T cells, are obtained by stimulating naive or antigen specific T lymphocytes with antigen. For example, antigen-specific T cell lines or clones can be generated to cytomegalovirus antigens by isolating T cells from infected subjects and stimulating the cells in vitro with the same antigen.

(448) B. Vectors and Methods for Genetic Engineering

(449) Also provided are methods, nucleic acids, compositions, and kits, for expressing the binding molecules, and for producing the genetically engineered cells expressing such binding molecules. The genetic engineering generally involves introduction of a nucleic acid encoding the binding molecule, e.g. TCR or CAR, e.g. TCR-like CAR, into the cell, such as by retroviral transduction, transfection, or transformation.

(450) In some embodiments, gene transfer is accomplished by first stimulating the cell, such as by combining it with a stimulus that induces a response such as proliferation, survival, and/or activation, e.g., as measured by expression of a cytokine or activation marker, followed by transduction of the activated cells, and expansion in culture to numbers sufficient for clinical applications.

(451) In some contexts, overexpression of a stimulatory factor (for example, a lymphokine or a cytokine) may be toxic to a subject. Thus, in some contexts, the engineered cells include gene segments that cause the cells to be susceptible to negative selection in vivo, such as upon administration in adoptive immunotherapy. For example in some aspects, the cells are engineered so that they can be eliminated as a result of a change in the in vivo condition of the patient to which they are administered. The negative selectable phenotype may result from the insertion of a gene that confers sensitivity to an administered agent, for example, a compound. Negative selectable genes include the Herpes simplex virus type I thymidine kinase (HSV-I TK) gene (Wigler et al., Cell 2:223, 1977) which confers ganciclovir sensitivity; the cellular hypoxanthine phosphribosyltransferase (HPRT) gene, the cellular adenine phosphoribosyltransferase (APRT) gene, bacterial cytosine deaminase, (Mullen et al., Proc. Natl. Acad. Sci. USA. 89:33 (1992)).

(452) In some aspects, the cells further are engineered to promote expression of cytokines or other factors. Various methods for the introduction of genetically engineered components are well known and may be used with the provided methods and compositions. Exemplary methods include those for transfer of nucleic acids encoding the binding molecules, including via viral, e.g., retroviral or lentiviral, transduction, transposons, and electroporation.

(453) In some embodiments, recombinant nucleic acids are transferred into cells using recombinant infectious virus particles, such as, e.g., vectors derived from simian virus 40 (SV40), adenoviruses, adeno-associated virus (AAV). In some embodiments, recombinant nucleic acids are transferred into T cells using recombinant lentiviral vectors or retroviral vectors, such as gamma-retroviral vectors (see, e.g., Koste et al. (2014) Gene Therapy 2014 Apr. 3. doi: 10.1038/gt.2014.25; Carlens et al. (2000) Exp Hematol 28(10): 1137-46; Alonso-Camino et al. (2013) Mol Ther Nucl Acids 2, e93; Park et al., Trends Biotechnol. 2011 Nov. 29(11): 550-557.

(454) In some embodiments, the retroviral vector has a long terminal repeat sequence (LTR), e.g., a retroviral vector derived from the Moloney murine leukemia virus (MoMLV), myeloproliferative sarcoma virus (MPSV), murine embryonic stem cell virus (MESV), murine stem cell virus (MSCV), spleen focus forming virus (SFFV). Most retroviral vectors are derived from murine retroviruses. In some embodiments, the retroviruses include those derived from any avian or mammalian cell source. The retroviruses typically are amphotropic, meaning that they are capable of infecting host cells of several species, including humans. In one embodiment, the gene to be expressed replaces the retroviral gag, pol and/or env sequences. A number of illustrative retroviral systems have been described (e.g., U.S. Pat. Nos. 5,219,740; 6,207,453; 5,219,740; Miller and Rosman (1989) BioTechniques 7:980-990; Miller, A. D. (1990) Human Gene Therapy 1:5-14; Scarpa et al. (1991) Virology 180:849-852; Burns et al. (1993) Proc. Natl. Acad. Sci. USA 90:8033-8037; and Boris-Lawrie and Temin (1993) Cur. Opin. Genet. Develop. 3:102-109.

(455) Methods of lentiviral transduction are known. Exemplary methods are described in, e.g., Wang et al. (2012) J. Immunother. 35(9): 689-701; Cooper et al. (2003) Blood. 101:1637-1644; Verhoeyen et al. (2009)Methods Mol Biol. 506: 97-114; and Cavalieri et al. (2003) Blood. 102(2): 497-505.

(456) In some embodiments, recombinant nucleic acids are transferred into T cells via electroporation (see, e.g., Chicaybam et al, (2013) PLoS ONE 8(3): e60298 and Van Tedeloo et al. (2000) Gene Therapy 7(16): 1431-1437). In some embodiments, recombinant nucleic acids are transferred into T cells via transposition (see, e.g., Manuri et al. (2010) Hum Gene Ther 21(4): 427-437; Sharma et al. (2013) Molec Ther Nucl Acids 2, e74; and Huang et al. (2009) Methods Mol Biol 506: 115-126). Other methods of introducing and expressing genetic material in immune cells include calcium phosphate transfection (e.g., as described in Current Protocols in Molecular Biology, John Wiley & Sons, New York. N.Y.), protoplast fusion, cationic liposome-mediated transfection; tungsten particle-facilitated microparticle bombardment (Johnston, Nature, 346: 776-777 (1990)); and strontium phosphate DNA co-precipitation (Brash et al., Mol.

V. Methods for Editing Endogenous Genes Encoding T Cell Receptor (TCR) and Engineering of Cells to Express the Binding Molecules by Targeted Integration

(462) In some aspects, the provided binding molecules, e.g., recombinant T cell receptor (TCR) or a fragment or ? chain thereof, are expressed in an engineered cell, e.g., an engineered T cell. In some embodiments, provided are genetically engineered T cells expressing any of the described binding molecules, e.g., recombinant TCRs or a fragment or ? chain thereof, provided herein, e.g., for adoptive cell therapy, and related compositions, methods, uses, and kits and articles of manufacture used for performing the methods. In some aspects, one or more endogenous genes and/or gene products (and/or expression thereof) in the engineered cells are modified, e.g., by gene editing. In some aspects, the gene editing results in reduction, deletion, elimination, knock-out or disruption of one or more endogenous gene products (and/or expression thereof) and/or targeted integration of exogenous, heterologous or transgene sequences, e.g., sequences encoding the binding molecule, e.g., recombinant TCR, via methods such as homology-directed repair (HDR). In some embodiments, immune cells are engineered to express any of the binding molecules, e.g., recombinant TCRs, and sequences encoding the binding molecule, e.g., recombinant TCR, can be targeted to a specific locus via gene editing methods such as HDR.

(463) In some embodiments, one or more endogenous genes and/or gene products (and/or expression thereof) in the provided cells, and/or compositions containing such cells, are reduced, deleted, eliminated, knocked-out or disrupted, e.g., by introduction of a genetic disruption such as a DNA break. In some embodiments, the genes and/or gene products, are reduced, deleted, eliminated, knocked-out or disrupted in any of the cells engineered to express any of the binding molecules, e.g., recombinant TCRs, provided herein. In some embodiments, provided are cells that have been engineered to express a binding molecule, e.g., a recombinant TCR, described herein, populations of such cells, compositions containing such cells and/or enriched for such cells.

(464) In some embodiments, one or more endogenous genes and/or gene products (and/or expression thereof) in the provided cells, and/or compositions containing such cells, are reduced, deleted, eliminated, knocked-out or disrupted, including one or more of the gene encoding (or product thereof) TCR alpha constant region (TRAC) and/or TCR beta constant region (TRBC; encoded in humans by TRBC1 or TRBC2), e.g., to reduce or prevent expression of the endogenous TCR in the cell, e.g. T cell, and/or ? chain thereof. In some embodiments, the genes and/or gene products, such as TRAC and/or TRBC, is reduced, deleted, eliminated, knocked-out or disrupted in any of the engineered cells provided herein and/or in any of the methods for producing engineered cells provided herein. In some embodiments, engineered cells and/or engineered cells produced by the methods are cells that have been engineered to express the binding molecule described herein, populations of such cells, compositions containing such cells and/or enriched for such cells. In some embodiments, genes and/or gene products, such as the TRAC and/or TRBC, is reduced, deleted, eliminated, knocked-out or disrupted in primary T cells, to reduce, delete, eliminate, knock-out or disrupt the expression of the endogenous TCR in primary T cells, e.g., that are engineered to express any of the T cell receptors described herein.

(465) In some embodiments, gene editing, e.g., via HDR, involves: i) introducing into an immune cell one or more agent(s) capable of inducing a genetic disruption of one or more target site(s) within a gene encoding a domain or region of a T cell receptor alpha (TCR?) chain and/or one or more gene(s) encoding a domain or region of a T cell receptor beta (TCR?) chain; and ii) introducing into the immune cell a polynucleotide, e.g., a template polynucleotide, comprising a transgene encoding a binding molecule, e.g., recombinant TCR or ? chain thereof, such as any of the provided recombinant TCRs, wherein the transgene encoding the a binding molecule, e.g., recombinant TCR or ? chain thereof is targeted at or near one of the at least one target site(s) via homology directed repair (HDR).

(466) In some aspects, polynucleotides, e.g., template polynucleotides, containing transgene sequence (also referred to herein as exogenous or heterologous nucleic acid sequences) encoding a binding molecule, e.g., recombinant TCR or ? chain thereof and sequences homologous to the region of genetic disruption, can be introduced into a cell containing a genetic disruption at the endogenous TRAC and/or TRBC loci. In some aspects, in the presence of the targeted genetic disruption, e.g., DNA break, the nucleic acid sequences can be used as a DNA repair template, to effectively copy and integrate the transgene sequence, e.g., nucleic acid sequences encoding the binding molecule, e.g., recombinant TCR or ? chain thereof, at or near the site of the targeted genetic disruption by HDR, based on homology between the endogenous gene sequence surrounding the target site and the 5 and/or 3 homology arms included in the template polynucleotide.

(467) In some embodiments, the genetically engineered cells are modified to contain TRAC and/or TRBC locus that contains nucleic acid sequences encoding any of the provided binding molecules, e.g., recombinant TCR or a fragment thereof. In some aspects, the TRAC and/or TRBC locus in the genetically engineered cell are modified, e.g., by gene editing, to include a transgene sequence encoding a binding molecule, e.g., recombinant TCR or ? chain thereof, that is integrated into an endogenous TRAC and/or TRBC locus, which normally encodes a TCR? or TCR? constant domains. In some embodiments, gene editing involves inducing a targeted genetic disruption in one or more of the endogenous genes encoding TCR? or TCR? constant domains, and homology-dependent repair (HDR), using one or more template polynucleotides containing a transgene encoding a binding molecule, e.g., recombinant TCR or ? chain thereof, thereby targeting integration of the transgene at the TRAC and/or TRBC locus. In some embodiments, the transgene encodes a portion of the recombinant TCR and is integrated in-frame into a TCR open reading frame and/or gene locus. In certain embodiments, the transgene encodes a portion of a recombinant TCR and is inserted in-frame within an endogenous open reading frame encoding a TCR constant domain. In some embodiments, the integration of the transgene into the locus modifies and/or results in a modified locus that encodes the full recombinant TCR.

(478) In particular embodiments, a genetic disruption is targeted at, near, or within the TRBC2 locus. In particular embodiments, the genetic disruption is targeted at, near, or within an open reading frame of the TRBC2 locus. In certain embodiments, the genetic disruption is targeted at, near, or within an open reading frame that encodes a TCR? constant domain.

(480) TABLE-US-00015 TABLE 15 Coordinates of exons and introns of exemplary human TRBC2 locus (GRCh38, Chromosome 7, forward strand). Start (GrCh38) End (GrCh38) Length 5 UTR and Exon 1 142,801,041 142,801,427 387 Intron 1-2 142,801,428 142,801,943 516 Exon 2 142,801,944 142,801,961 18 Intron 2-3 142,801,962 142,802,104 143 Exon 3 142,802,105 142,802,211 107 Intron 3-4 142,802,212 142,802,502 291 Exon 4 and 3 UTR 142,802,503 142,802,748 246

In some embodiments, the TRBC1 gene is knocked out. In some embodiments, the TRBC2 gene is knocked out. In some embodiments, the TRAC gene and the TRBC1 gene are knocked out. In some embodiments, the TRAC gene and the TRBC2 gene are knocked out. In some embodiments, the TRAC gene and both the TRBC1 and TRBC2 genes are knocked out, e.g., targeting a sequence that is conserved between TRBC1 and TRBC2.

(482) In some embodiments, reducing or preventing endogenous TCR expression can lead to a reduced risk or chance of mispairing between chains of the engineered TCR and the endogenous TCR, thereby creating a new TCR that could potentially result in a higher risk of undesired or unintended antigen recognition and/or side effects, and/or could reduce expression levels of the desired exogenous TCR. In some aspects, reducing or preventing endogenous TCR expression can increase expression of the engineered TCR in the cells as compared to cells in which expression of the TCR is not reduced or prevented, such as increased by 1.5-fold, 2-fold, 3-fold, 4-fold, 5-fold or more. For example, in some cases, suboptimal expression of an engineered or recombinant TCR can occur due to competition with an endogenous TCR and/or with TCRs having mispaired chains, for the invariant CD3 signaling molecules that are involved in permitting expression of the complex on the cell surface.

(483) In some embodiments, the reduction, deletion, elimination, knockout or disruption involve the use of one or more agent(s) capable of introducing a genetic disruption, a cleavage, a double strand break (DSB) and/or a nick at a target site in the genomic DNA, resulting in a the reduction, deletion, elimination, knockout or disruption after repair by various cellular DNA repair mechanisms.

(484) In some embodiments, the one or more agent(s) capable of introducing a cleavage comprises a DNA binding protein or DNA-binding nucleic acid that specifically binds to or hybridizes to a target site in the genome, e.g., in TRAC and/or TRBC genes. In some aspects, the targeted cleavage, e.g., DNA break, of the endogenous genes encoding TCR is achieved using a protein or a nucleic acid is coupled to or complexed with a gene editing nuclease, such as in a chimeric or fusion protein. In some embodiments, the one or more agent(s) capable of introducing a cleavage comprises a fusion protein comprising a DNA-targeting protein and a nuclease or an RNA-guided nuclease.

(485) In some embodiments, reduction, deletion, elimination, knockout or disruption is carried out by gene editing methods, such as using a zinc finger nuclease (ZFN), TALEN or a CRISPR/Cas system with an engineered single guide RNA that cleaves a TCR gene. In some embodiments, reducing expression of an endogenous TCR is carried out using an inhibitory nucleic acid molecule against a target nucleic acids encoding specific TCRs (e.g., TCR-? and TCR-?). In some embodiments, the inhibitory nucleic acid is or contains or encodes a small interfering RNA (siRNA), a microRNA-adapted shRNA, a short hairpin RNA (shRNA), a hairpin siRNA, a microRNA (miRNA-precursor) or a microRNA (miRNA). Exemplary methods for reducing or preventing endogenous TCR expression are known in the art, see e.g. U.S. Pat. No. 9,273,283; U.S. publication no. US2014/0301990; and PCT publication No. WO2015/161276.

(486) In some embodiments, the agent capable of introducing a targeted cleavage comprises various components, such as a fusion protein comprising a DNA-targeting protein and a nuclease or an RNA-guided nuclease. In some embodiments, the targeted cleavage is carried out using a DNA-targeting molecule that includes a DNA-binding protein such as one or more zinc finger protein (ZFP) or transcription activator-like effectors (TALEs), fused to a nuclease, such as an endonuclease. In some embodiments, the targeted cleavage is carried out using RNA-guided nucleases such as a clustered regularly interspaced short palindromic nucleic acid (CRISPR)-associated nuclease (Cas) system (including Cas and/or Cfp1). In some embodiments, the targeted cleavage is carried using agents capable of introducing a cleavage, such as sequence-specific or targeted nucleases, including DNA-binding targeted nucleases and gene editing nucleases such as zinc finger nucleases (ZFN) and transcription activator-like effector nucleases (TALENs), and RNA-guided nucleases such as a CRISPR-associated nuclease (Cas) system, specifically engineered and/or designed to be targeted to the at least one target site(s), sequence of a gene or a portion thereof.

(487) 1. Engineered Nucleases

(488) In some embodiments, the one or more agent(s) specifically targets the at least one target site(s), e.g., at or near TRAC and/or TRBC genes. In some embodiments, the agent comprises a ZFN, TALEN or a CRISPR/Cas9 combination that specifically binds to, recognizes, or hybridizes to the target site(s). In some embodiments, the CRISPR/Cas9 system includes an engineered crRNA/tracr RNA (single guide RNA) to guide specific cleavage. In some embodiments, the agent comprises nucleases based on the Argonaute system (e.g., from T. thermophilus, known as TtAgo, (Swarts et al. (2014) Nature 507(7491): 258-261).

(489) Zinc finger proteins (ZFPs), transcription activator-like effectors (TALEs), and CRISPR system binding domains can be engineered to bind to a predetermined nucleotide sequence, for example via engineering (altering one or more amino acids) of the recognition helix region of a naturally occurring ZFP or TALE protein. Engineered DNA binding proteins (ZFPs or TALEs) are proteins that are non-naturally occurring. Rational criteria for design include application of substitution rules and computerized algorithms for processing information in a database storing information of existing ZFP and/or TALE designs and binding data. See, e.g., U.S. Pat. Nos. 6,140,081; 6,453,242; and 6,534,261; see also WO 98/53058; WO 98/53059; WO 98/53060; WO 02/016536 and WO 03/016496 and U.S. Publication No. 20110301073. Exemplary ZFNs, TALEs, and TALENs are described in, e.g., Lloyd et al., Frontiers in Immunology, 4(221): 1-7 (2013).

(490) In some embodiments, an engineered zinc finger protein, TALE protein or CRISPR/Cas system is not found in nature and whose production results primarily from an empirical process such as phage display, interaction trap or hybrid selection. See e.g., U.S. Pat. Nos. 5,789,538; 5,925,523; 6,007,988; 6,013,453; 6,200,759; WO 95/19431; WO 96/06166; WO 98/53057; WO 98/54311; WO 00/27878; WO 01/60970; WO 01/88197 and WO 02/099084.

(491) In some embodiments, the TRAC and/or TRBC genes can be targeted for cleavage by engineered ZFNs. Exemplary ZFN that target endogenous T cell receptor (TCR) genes include those described in, e.g., US 2015/0164954, US 2011/0158957, US 2015/0056705, U.S. Pat. No. 8,956,828 and Torikawa et al. (2012) Blood 119:5697-5705, the disclosures of which are incorporated by reference in their entireties.

(492) In some embodiments, the TRAC and/or TRBC genes can be targeted for cleavage by engineered TALENs. Exemplary TALEN that target endogenous T cell receptor (TCR) genes include those described in, e.g., WO 2017/070429, WO 2015/136001, US20170016025 and US20150203817, the disclosures of which are incorporated by reference in their entireties.

(493) 2 CRISPR Related Methods

(494) In some embodiments, the TRAC and/or TRBC genes can be targeted for cleavage using clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins. See Sander and Joung, (2014) Nature Biotechnology, 32(4): 347-355. In some embodiments, CRISPR system refers collectively to transcripts and other elements involved in the expression of or directing the activity of CRISPR-associated (Cas) genes, including sequences encoding a Cas gene, a tracr (trans-activating CRISPR) sequence (e.g. tracrRNA or an active partial tracrRNA), a tracr-mate sequence (encompassing a direct repeat and a tracrRNA-processed partial direct repeat in the context of an endogenous CRISPR system), a guide sequence (also referred to as a spacer in the context of an endogenous CRISPR system), and/or other sequences and transcripts from a CRISPR locus.

(495) In some aspects, the CRISPR/Cas nuclease or CRISPR/Cas nuclease system includes a non-coding guide RNA (gRNA), which sequence-specifically binds to DNA, and a Cas protein (e.g., Cas9), with nuclease functionality.

(496) In some embodiments, gene editing results in an insertion or a deletion at the targeted locus, or a knock-out of the targeted locus and elimination of the expression of the encoded protein. In some embodiments, the gene editing is achieved by non-homologous end joining (NHEJ) using a CRISPR/Cas9 system. In some embodiments, one or more guide RNA (gRNA) molecule can be used with one or more Cas9 nuclease, Cas9 nickase, enzymatically inactive Cas9 or variants thereof. Exemplary features of the gRNA molecule(s) and the Cas9 molecule(s) are described below.

(497) In some embodiments, the CRISPR/Cas nuclease system comprises at least one of: a guide RNA (gRNA) having a targeting domain that is complementary with a target site of a TRAC gene; a gRNA having a targeting domain that is complementary with a target site of one or both of a TRBC1 and a TRBC2 gene; or at least one nucleic acid encoding the gRNA.

(498) In some embodiments, a guide sequence, e.g., guide RNA, is any polynucleotide sequences comprising at least a sequence portion, e.g., targeting domain, that has sufficient complementarity with a target site sequence, such as a target site in the TRAC, TRBC1 and/or TRBC2 genes in humans, to hybridize with the target sequence at the target site and direct sequence-specific binding of the CRISPR complex to the target sequence. In some embodiments, in the context of formation of a CRISPR complex, target site (also known as target position, target DNA sequence or target location) can refer to a sequence to which a guide sequence is designed to have complementarity, where hybridization between the target sequence and a domain, e.g., targeting domain, of the guide RNA promotes the formation of a CRISPR complex. Full complementarity is not necessarily required, provided there is sufficient complementarity to cause hybridization and promote formation of a CRISPR complex. In some embodiments, a guide sequence is selected to reduce the degree of secondary structure within the guide sequence. Secondary structure may be determined by any suitable polynucleotide folding algorithm.

(499) In some aspects, a CRISPR enzyme (e.g. Cas9 nuclease) in combination with (and optionally complexed with) a guide sequence is delivered to the cell. For example, one or more elements of a CRISPR system is derived from a type I, type II, or type III CRISPR system. For example, one or more elements of a CRISPR system are derived from a particular organism comprising an endogenous CRISPR system, such as Streptococcus pyogenes, Staphylococcus aureus or Neisseria meningitides.

(500) In some embodiments, a guide RNA (gRNA) specific to the target site (e.g. TRAC, TRBC1 and/or TRBC2 in humans) is used with RNA-guided nucleases, e.g., Cas, to introduce a DNA break at the target site or target position. Methods for designing gRNAs and exemplary targeting domains can include those described in, e.g., International PCT Publication No. WO2015/161276. Targeting domains can be incorporated into the gRNA that is used to target Cas9 nucleases to the target site or target position.

(2014) Nat. Methods, 11:783-4). In some aspects, the gRNA sequence is or comprises a sequence with minimal off-target binding to a non-target site or position.

(502) a) Guide RNA (gRNA) Molecules

(503) In some embodiments, the agent comprises a gRNA that targets a region of the TRAC, TRBC1 and/or TRBC2 loci. A gRNA molecule refers to a nucleic acid that promotes the specific targeting or homing of a gRNA molecule/Cas9 molecule complex to a target nucleic acid, such as a locus on the genomic DNA of a cell. gRNA molecules can be unimolecular (having a single RNA molecule), sometimes referred to herein as chimeric gRNAs, or modular (comprising more than one, and typically two, separate RNA molecules).

(504) Several exemplary gRNA structures, with domains indicated thereon, are provided in FIGS. 14A-14G. While not wishing to be bound by theory, with regard to the three dimensional form, or intra- or inter-strand interactions of an active form of a gRNA, regions of high complementarity are sometimes shown as duplexes in FIGS. 14A-14G and other depictions provided herein.

(505) In some cases, the gRNA is a unimolecular or chimeric gRNA comprising, from 5 to 3: a targeting domain which is complementary to a target nucleic acid, such as a sequence from the TRAC, TRBC1 and/or TRBC2 genes (coding sequences set forth in SEQ ID NOS: 348, 349 and 1047, respectively); a first complementarity domain; a linking domain; a second complementarity domain (which is complementary to the first complementarity domain); a proximal domain; and optionally, a tail domain.

(506) In other cases, the gRNA is a modular gRNA comprising first and second strands. In these cases, the first strand preferably includes, from 5 to 3: a targeting domain (which is complementary to a target nucleic acid, such as a sequence from the TRAC, TRBC1 and/or TRBC2 genes, coding sequence set forth in SEQ ID NOS: 348, 349 and 1047, respectively) and a first complementarity domain. The second strand generally includes, from 5 to 3: optionally, a 5 extension domain; a second complementarity domain; a proximal domain; and optionally, a tail domain.

(507) In some cases, the gRNA is a unimolecular or chimeric gRNA comprising, from 5 to 3: a targeting domain which targets a target site or position, such within as a sequence from the TRAC locus (exemplary nucleotide sequence of the human TRAC gene locus set forth in SEQ ID NO:348; NCBI Reference Sequence: NG_001332.3, TRAC; exemplary genomic sequence described in Table 13 herein); a first complementarity domain; a linking domain; a second complementarity domain (which is complementary to the first complementarity domain); a proximal domain; and optionally, a tail domain. In some cases, the gRNA is a unimolecular or chimeric gRNA comprising, from 5 to 3: a targeting domain which targets a target site or position, such as within a sequence from the TRBC1 or TRBC2 locus (exemplary nucleotide sequence of the human TRBC1 gene locus set forth in SEQ ID NO: 349; NCBI Reference Sequence: NG_001333.2, TRBC1; exemplary genomic sequence described in Table 14 herein; exemplary nucleotide sequence of the human TRBC2 gene locus set forth in SEQ ID NO:1047; NCBI Reference Sequence: NG_001333.2, TRBC2; exemplary genomic sequence described in Table 15 herein); a first complementarity domain; a linking domain; a second complementarity domain (which is complementary to the first complementarity domain); a proximal domain; and optionally, a tail domain.

(508) In other cases, the gRNA is a modular gRNA comprising first and second strands. In these cases, the first strand preferably includes, from 5 to 3: a targeting domain (which targets a target site or position, such as within a sequence from TRAC locus (exemplary nucleotide sequence of the human TRAC gene locus set forth in SEQ ID NO:348; NCBI Reference Sequence: NG_001332.3, TRAC; exemplary genomic sequence described in Table 13 herein) or TRBC1 or TRBC2 locus (exemplary nucleotide sequence of the human TRBC1 gene locus set forth in SEQ ID NO: 349; NCBI Reference Sequence: NG_001333.2, TRBC11; exemplary genomic sequence described in Table 14 herein; exemplary nucleotide sequence of the human TRBC2 gene locus set forth in SEQ ID NO:1047; NCBI Reference Sequence: NG_001333.2, TRBC2); and a first complementarity domain. The second strand generally includes, from 5 to 3: optionally, a 5 extension domain; a second complementarity domain; a proximal domain; and optionally, a tail domain.

(509) These domains are discussed briefly below:

(1) The Targeting Domain

(510) FIGS. 14A-14G provide examples of the placement of targeting domains.

(511) The targeting domain comprises a nucleotide sequence that is complementary, e.g., at least 80, 85, 90, 95, 98 or 99% complementary, e.g., fully complementary, to the target sequence on the target nucleic acid. The strand of the target nucleic acid comprising the target sequence is referred to herein as the complementary strand of the target nucleic acid. Guidance on the selection of targeting domains can be found, e.g., in Fu Y et al., Nat Biotechnol 2014 (doi: 10.1038/nbt.2808) and Sternberg S H et al., Nature 2014 (doi: 10.1038/nature13011).

(512) The targeting domain is part of an RNA molecule and will therefore comprise the base uracil (U), while any DNA encoding the gRNA molecule will comprise the base thymine (T). While not wishing to be bound by theory, in an embodiment, it is believed that the complementarity of the targeting domain with the target sequence contributes to specificity of the interaction of the gRNA molecule/Cas9 molecule complex with a target nucleic acid. It is understood that in a targeting domain and target sequence pair, the uracil bases in the targeting domain will pair with the adenine bases in the target sequence. In an embodiment, the target domain itself comprises in the 5 to 3 direction, an optional secondary domain, and a core domain. In an embodiment, the core domain is fully complementary with the target sequence. In an embodiment, the targeting domain is 5 to 50 nucleotides in length. The strand of the target nucleic acid with which the targeting domain is complementary is referred to herein as the complementary strand. Some or all of the nucleotides of the domain can have a modification, e.g., to render it less susceptible to degradation, improve bio-compatibility, etc. By way of non-limiting example, the backbone of the target domain can be modified with a phosphorothioate, or other modification(s). In some cases, a nucleotide of the targeting domain can comprise a 2 modification, e.g., a 2-acetylation, e.g., a 2 methylation, or other modification(s).

(513) In various embodiments, the targeting domain is 16-26 nucleotides in length (i.e. it is 16 nucleotides in length, or 17 nucleotides in length, or 18, 19, 20, 21, 22, 23, 24, 25 or 26 nucleotides in length.

(2) Exemplary Targeting Domains

(514) In some embodiments, when the T cell target knockout position is the TRAC coding region, e.g., an early coding region, and more than one gRNA is used to position breaks, e.g., two single stranded breaks or two double stranded breaks, or a combination of single strand and double strand breaks, e.g., to create one or more indels, in the target nucleic acid sequence, each guide RNA is independently selected from one of Tables 25A-G or Table 29 of International PCT Pub. No. WO2015161276.

(515) In another embodiment, when the T cell target knockout position is the TRAC coding region, e.g., an early coding region, and more than one gRNA is used to position breaks, e.g., two single stranded breaks or two double stranded breaks, or a combination of single strand and double strand breaks, e.g., to create one or more indels, in the target nucleic acid sequence, each guide RNA is independently selected from one of Tables 25A-G or Table 29 of International PCT Pub. No. WO2015161276 so that the break is generated with over 10% efficiency.

(516) In an embodiment, when the T cell target knockout position is the TRBC coding region, e.g., an early coding region, and more than one gRNA is used to position breaks, e.g., two single stranded breaks or two double stranded breaks, or a combination of single strand and double strand breaks, e.g., to create one or more indels, in the target nucleic acid sequence, each guide RNA is independently selected from one of Tables 26A-G or Table 27 of International PCT Pub. No. WO2015161276.

(517) In an embodiment, when the T cell target knockout position is the TRBC coding region, e.g., an early coding region, and more than one gRNA is used to position breaks, e.g., two single stranded breaks or two double stranded breaks, or a combination of single strand and double strand breaks, e.g., to create one or more indels, in the target nucleic acid sequence, each guide RNA is independently selected from one of Tables 26A-G or Table 27 of International PCT Pub. No. WO2015161276 so that the break is generated with over 10% efficiency.

(518) In some embodiments, exemplary guide RNA targeting domain sequence includes any of those described in International PCT Pub. No. WO2015161276.

In an embodiment, two gRNAs are used to target two Cas9 nucleases or two Cas9 nickases, e.g., a gRNA with a targeting domain from Group A can be paired with a gRNA with a targeting domain from Group B as shown in Table 25-1 of International PCT Pub.

In some embodiments, the genetic disruption, e.g., DNA break, is targeted at early coding region of a gene of interest, e.g., TRAC, TRBC1 and/or TRBC2, including sequence immediately following a transcription start site, within a first exon of the coding sequence, or within 500 bp of the transcription start site (e.g., less than 500, 450, 400, 350, 300, 250, 200, 150, 100 or 50 bp), or within 500 bp of the start codon (e.g., less than 500, 450, 400, 350, 300, 250, 200, 150, 100 or 50 bp).

In particular embodiments, the target site is within an exon within the open reading frame of the TRAC, TRBC1, and/or TRBC2 locus.

(536) In particular embodiments, the genetic disruption, e.g., DNA break, is targeted at or within an open reading frame of a gene or locus of interest, e.g., TRAC, TRBC1, and/or TRBC2. In some embodiments, the genetic disruption is targeted at or within an intron within the open reading frame of a gene or locus of interest. In some embodiments, the genetic disruption is targeted within an exon within the open reading frame of the gene or locus of interest.

(537) In particular embodiments, a genetic disruption, e.g., DNA break, is targeted at or within an intron. In certain embodiments, a genetic disruption, e.g., DNA break, is targeted at or within an exon. In some embodiments, a genetic disruption, e.g., DNA break, is targeted at or within an exon of a gene of interest, e.g., TRAC, TRBC1 and/or TRBC2.

(538) In some embodiments, a genetic disruption, e.g., DNA break, is targeted within an exon of the TRAC gene, open reading frame, or locus. In certain embodiments, the genetic disruption is within the first exon, second exon, third exon, or fourth exon of the TRAC gene, open reading frame, or locus. In particular embodiments, the genetic disruption is within the first exon of the TRAC gene, open reading frame, or locus.

(545) In some embodiments, the gRNA for targeting TRAC, TRBC1 and/or TRBC2 can be any that are described herein, or are described elsewhere, e.g., in WO2015/161276, WO2017/193107, WO2017/093969, US2016/272999 and US2015/056705 or a targeting domain that can bind to the targeting sequences described in the foregoing. In some embodiments, the sequence targeted by the CRISPR/Cas9 gRNA in the TRAC gene locus is GAGAATCAAAATCGGTGAAT (SEQ ID NO: 1348) or ATTCACCGATTTTGATTCTC (SEQ ID NO:1182). In some embodiments, the sequence targeted by the CRISPR/Cas9 gRNA in the TRBC1 and/or TRBC2 gene loci is GGCCTCGGCGCTGACGATCT (SEQ ID NO: 1349) or AGATCGTCAGCGCCGAGGCC (SEQ ID NO:1054). In some embodiments, the gRNA targeting domain sequence for targeting a target site in the TRAC gene locus is GAGAAUCAAAAUCGGUGAAU (SEQ ID NO: 1048). In some embodiments, the gRNA targeting domain sequence for targeting a target site in the TRBC1 and/or TRBC2 gene loci is GGCCUCGGCGCUGACGAUCU (SEQ ID NO: 1053).

(546) In some embodiments, the gRNA for targeting the TRAC gene locus can be obtained by in vitro transcription of the sequence

(set forth in SEQ ID NO: 1350; bold and underlined portion is complementary to the target site in the TRAC locus), or chemically synthesized, where the gRNA had the sequence 5-

(set forth in SEQ ID NO: 1351; see Osborn et al., Mol Ther. 24(3):570-581 (2016)). Other exemplary gRNA sequences, or targeting domains contained in the gRNA and/or other methods of gene editing and/or knock-out targeting endogenous TCR genes, e.g., TRAC and/or TRBC genes, include any described in, e.g. U.S. Publication Nos. US2011/0158957, US2014/0301990, US2015/0098954, US2016/0208243; US2016/272999 and US2015/056705; International PCT Publication Nos. WO2014/191128, WO2015/136001, WO2015/161276, WO2016/069283, WO2016/016341, WO2017/193107, and WO2017/093969; and Osborn et al. (2016) Mol. Ther. 24(3):570-581. Any of the known methods can be used to generate a cleavage of the endogenous genes encoding TCR domains or regions can be used in the embodiments provided herein, e.g., for engineering in cell lines and/or in primary T cells.

(549) In some embodiments, targeting domains include those for knocking out the TRAC, TRBC1 and/or TRBC2 genes using S. pyogenes Cas9, S. aureus Cas9 or using N. meningitidis Cas9.

(550) In some embodiments, targeting domains include those for knocking out the TRAC, TRBC1 and/or TRBC2 genes using S. pyogenes Cas9. Any of the targeting domains can be used with a S. pyogenes Cas9 molecule that generates a double stranded break (Cas9 nuclease) or a single-stranded break (Cas9 nickase).

(551) In an embodiment, dual targeting is used to create two nicks on opposite DNA strands by using S. pyogenes Cas9 nickases with two targeting domains that are complementary to opposite DNA strands, e.g., a gRNA comprising any minus strand targeting domain may be paired with any gRNA comprising a plus strand targeting domain. In some embodiments, the two gRNAs are oriented on the DNA such that PAMs face outward and the distance between the 5 ends of the gRNAs is 0-50 bp. In an embodiment, two gRNAs are used to target two Cas9 nucleases or two Cas9 nickases, for example, using a pair of Cas9 molecule/gRNA molecule complex guided by two different gRNA molecules to cleave the target domain with two single stranded breaks on opposing strands of the target domain. In some embodiments, the two Cas9 nickases can include a molecule having HNH activity, e.g., a Cas9 molecule having the RuvC activity inactivated, e.g., a Cas9 molecule having a mutation at D10, e.g., the D10A mutation, a molecule having RuvC activity, e.g., a Cas9 molecule having the HNH activity inactivated, e.g., a Cas9 molecule having a mutation at H840, e.g., a H840A, or a molecule having RuvC activity, e.g., a Cas9 molecule having the HNH activity inactivated, e.g., a Cas9 molecule having a mutation at N863, e.g., N863A. In some embodiments, each of the two gRNAs are complexed with a D10A Cas9 nickase.

(3) The First Complementarity Domain

(552) FIGS. 14A-14G provide examples of first complementarity domains. The first complementarity domain is complementary with the second complementarity domain described below, and generally has sufficient complementarity to the second complementarity domain to form a duplexed region under at least some physiological conditions. The first complementarity domain is typically 5 to 30 nucleotides in length, and may be 5 to 25 nucleotides in length, 7 to 25 nucleotides in length, 7 to 22 nucleotides in length, 7 to 18 nucleotides in length, or 7 to 15 nucleotides in length. In various embodiments, the first complementary domain is 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 nucleotides in length.

(553) Typically, the first complementarity domain does not have exact complementarity with the second complementarity domain target. In some embodiments, the first complementarity domain can have 1, 2, 3, 4 or 5 nucleotides that are not complementary with the corresponding nucleotide of the second complementarity domain. For instance, a segment of 1, 2, 3, 4, 5 or 6, (e.g., 3) nucleotides of the first complementarity domain may not pair in the duplex, and may form a non-duplexed or looped-out region. In some instances, an unpaired, or loop-out, region, e.g., a loop-out of 3 nucleotides, is present on the second complementarity domain. This unpaired region optionally begins 1, 2, 3, 4, 5, or 6, e.g., 4, nucleotides from the 5 end of the second complementarity domain.

(554) The first complementarity domain can include 3 subdomains, which, in the 5 to 3 direction are: a 5 subdomain, a central subdomain, and a 3 subdomain. In an embodiment, the 5 subdomain is 4-9, e.g., 4, 5, 6, 7, 8 or 9 nucleotides in length. In an embodiment, the central subdomain is 1, 2, or 3, e.g., 1, nucleotide in length. In an embodiment, the 3 subdomain is 3 to 25, e.g., 4-22, 4-18, or 4 to 10, or 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25, nucleotides in length.

(555) In some embodiments, the first and second complementarity domains, when duplexed, comprise 11 paired nucleotides, for example, in the gRNA sequence (one paired strand underlined, one bolded):

(557) In some embodiments, the first and second complementarity domains, when duplexed, comprise 15 paired nucleotides, for example in the gRNA sequence (one paired strand underlined, one bolded):

(559) In some embodiments the first and second complementarity domains, when duplexed, comprise 16 paired nucleotides, for example in the gRNA sequence (one paired strand underlined, one bolded):

(563) In some embodiments, nucleotides are exchanged to remove poly-U tracts, for example in the gRNA sequences (exchanged nucleotides underlined):

(565) The first complementarity domain can share homology with, or be derived from, a naturally occurring first complementarity domain. In an embodiment, it has at least 50% homology with a first complementarity domain disclosed herein, e.g., an S. pyogenes, S. aureus, N. meningtidis, or S. thermophilus, first complementarity domain.

(566) It should be noted that one or more, or even all of the nucleotides of the first complementarity domain, can have a modification along the lines discussed above for the targeting domain.

(4) The Linking Domain

(567) FIGS. 14A-14G provide examples of linking domains.

(568) In a unimolecular or chimeric gRNA, the linking domain serves to link the first complementarity domain with the second complementarity domain of a unimolecular gRNA. The linking domain can link the first and second complementarity domains covalently or non-covalently. In an embodiment, the linkage is covalent. In an embodiment, the linking domain covalently couples the first and second complementarity domains, see, e.g., FIGS. 14B-14E. In an embodiment, the linking domain is, or comprises, a covalent bond interposed between the first complementarity domain and the second complementarity domain. Typically the linking domain comprises one or more, e.g., 2, 3, 4, 5, 6, 7, 8, 9, or 10 nucleotides, but in various embodiments the linker can be 20, 30, 40, 50 or even 100 nucleotides in length.

(569) In modular gRNA molecules, the two molecules are associated by virtue of the hybridization of the complementarity domains and a linking domain may not be present. See e.g., FIG. 14A.

(570) A wide variety of linking domains are suitable for use in unimolecular gRNA molecules. Linking domains can consist of a covalent bond, or be as short as one or a few nucleotides, e.g., 1, 2, 3, 4, or 5 nucleotides in length. In an embodiment, a linking domain is 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, or 25 or more nucleotides in length. In an embodiment, a linking domain is 2 to 50, 2 to 40, 2 to 30, 2 to 20, 2 to 10, or 2 to 5 nucleotides in length. In an embodiment, a linking domain shares homology with, or is derived from, a naturally occurring sequence, e.g., the sequence of a tracrRNA that is 5 to the second complementarity domain. In an embodiment, the linking domain has at least 50% homology with a linking domain disclosed herein.

(571) As discussed above in connection with the first complementarity domain, some or all of the nucleotides of the linking domain can include a modification.

(5) The 5 Extension Domain

(572) In some cases, a modular gRNA can comprise additional sequence, 5 to the second complementarity domain, referred to herein as the 5 extension domain, see, e.g., FIG. 14A. In an embodiment, the 5 extension domain is, 2-10, 2-9, 2-8, 2-7, 2-6, 2-5, or 2-4 nucleotides in length. In an embodiment, the 5 extension domain is 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more nucleotides in length.

(6) The Second Complementarity Domain

(573) FIGS. 14A-14G provide examples of second complementarity domains. The second complementarity domain is complementary with the first complementarity domain, and generally has sufficient complementarity to the second complementarity domain to form a duplexed region under at least some physiological conditions. In some cases, e.g., as shown in FIGS. 14A-14B, the second complementarity domain can include sequence that lacks complementarity with the first complementarity domain, e.g., sequence that loops out from the duplexed region.

(574) The second complementarity domain may be 5 to 27 nucleotides in length, and in some cases may be longer than the first complementarity region. For instance, the second complementary domain can be 7 to 27 nucleotides in length, 7 to 25 nucleotides in length, 7 to 20 nucleotides in length, or 7 to 17 nucleotides in length. More generally, the complementary domain may be 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, or 26 nucleotides in length.

(575) In an embodiment, the second complementarity domain comprises 3 subdomains, which, in the 5 to 3 direction are: a 5 subdomain, a central subdomain, and a 3 subdomain. In an embodiment, the 5 subdomain is 3 to 25, e.g., 4 to 22, 4 to 18, or 4 to 10, or 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 nucleotides in length. In an embodiment, the central subdomain is 1, 2, 3, 4 or 5, e.g., 3, nucleotides in length. In an embodiment, the 3 subdomain is 4 to 9, e.g., 4, 5, 6, 7, 8 or 9 nucleotides in length.

(576) In an embodiment, the 5 subdomain and the 3 subdomain of the first complementarity domain, are respectively, complementary, e.g., fully complementary, with the 3 subdomain and the 5 subdomain of the second complementarity domain.

(577) The second complementarity domain can share homology with or be derived from a naturally occurring second complementarity domain. In an embodiment, it has at least 50% homology with a second complementarity domain disclosed herein, e.g., an S. pyogenes, S. aureus, N. meningtidis, or S. thermophilus, first complementarity domain.

(578) Some or all of the nucleotides of the second complementarity domain can have a modification, e.g., a modification found in Section VIII herein.

(7) The Proximal Domain

(579) FIGS. 14A-14G provide examples of proximal domains

(580) In an embodiment, the proximal domain is 5 to 20 nucleotides in length. In an embodiment, the proximal domain can share homology with or be derived from a naturally occurring proximal domain. In an embodiment, it has at least 50% homology with a proximal domain disclosed herein, e.g., an S. pyogenes, S. aureus, N. meningtidis, or S. thermophilus, proximal domain.

(581) Some or all of the nucleotides of the proximal domain can have a modification along the lines described above.

(8) The Tail Domain

(582) FIGS. 14A-14G provide examples of tail domains.

(583) As can be seen by inspection of the tail domains in FIG. 14A and FIGS. 14B-14F, a broad spectrum of tail domains are suitable for use in gRNA molecules.

(611) A Cas9 molecule, or Cas9 polypeptide, as that term is used herein, refers to a molecule or polypeptide that can interact with a gRNA molecule and, in concert with the gRNA molecule, homes or localizes to a site which comprises a target domain and PAM sequence. Cas9 molecule and Cas9 polypeptide, as those terms are used herein, refer to naturally occurring Cas9 molecules and to engineered, altered, or modified Cas9 molecules or Cas9 polypeptides that differ, e.g., by at least one amino acid residue, from a reference sequence, e.g., the most similar naturally occurring Cas9 molecule or the sequence of amino acids set forth in SEQ ID NOS: 1331-1336, 1338, 1340 and 1341

(612) (1) Cas9 Domains

(613) Crystal structures have been determined for two different naturally occurring bacterial Cas9 molecules (Jinek et al., Science, 343(6176):1247997, 2014) and for S. pyogenes Cas9 with a guide RNA (e.g., a synthetic fusion of crRNA and tracrRNA) (Nishimasu et al., Cell, 156:935-949, 2014; and Anders et al., Nature, 2014, doi: 10.1038/nature13579).

(614) A naturally occurring Cas9 molecule comprises two lobes: a recognition (REC) lobe and a nuclease (NUC) lobe; each of which further comprises domains described herein. The domain nomenclature and the numbering of the amino acid residues encompassed by each domain used throughout this disclosure is as described in Nishimasu et al. The numbering of the amino acid residues is with reference to Cas9 from S. pyogenes.

(615) The REC lobe comprises the arginine-rich bridge helix (BH), the REC1 domain, and the REC2 domain. The REC lobe does not share structural similarity with other known proteins, indicating that it is a Cas9-specific functional domain. The BH domain is a long ?-helix and arginine rich region and comprises amino acids 60-93 of the sequence of S. pyogenes Cas9. The REC1 domain is important for recognition of the repeat: anti-repeat duplex, e.g., of a gRNA or a tracrRNA, and is therefore critical for Cas9 activity by recognizing the target sequence. The REC1 domain comprises two REC1 motifs at amino acids 94 to 179 and 308 to 717 of the sequence of S. pyogenes Cas9. These two REC1 domains, though separated by the REC2 domain in the linear primary structure, assemble in the tertiary structure to form the REC1 domain. The REC2 domain, or parts thereof, may also play a role in the recognition of the repeat:anti-repeat duplex. The REC2 domain comprises amino acids 180-307 of the sequence of S. pyogenes Cas9.

(616) The NUC lobe comprises the RuvC domain (also referred to herein as RuvC-like domain), the HNH domain (also referred to herein as HNH-like domain), and the PAM-interacting (PI) domain. The RuvC domain shares structural similarity to retroviral integrase superfamily members and cleaves a single strand, e.g., the non-complementary strand of the target nucleic acid molecule. The RuvC domain is assembled from the three split RuvC motifs (RuvC I, RuvCII, and RuvCIII, which are often commonly referred to in the art as RuvCI domain, or N-terminal RuvC domain, RuvCII domain, and RuvCIII domain) at amino acids 1-59, 718-769, and 909-1098, respectively, of the sequence of S. pyogenes Cas9. Similar to the REC1 domain, the three RuvC motifs are linearly separated by other domains in the primary structure, however in the tertiary structure, the three RuvC motifs assemble and form the RuvC domain. The HNH domain shares structural similarity with HNH endonucleases, and cleaves a single strand, e.g., the complementary strand of the target nucleic acid molecule. The HNH domain lies between the RuvC II-III motifs and comprises amino acids 775-908 of the sequence of S. pyogenes Cas9. The PI domain interacts with the PAM of the target nucleic acid molecule, and comprises amino acids 1099-1368 of the sequence of S. pyogenes Cas9.

(617) (a) A RuvC-Like Domain and an HNH-Like Domain

(618) In an embodiment, a Cas9 molecule or Cas9 polypeptide comprises an HNH-like domain and a RuvC-like domain. In an embodiment, cleavage activity is dependent on a RuvC-like domain and an HNH-like domain. A Cas9 molecule or Cas9 polypeptide, e.g., an eaCas9 molecule or eaCas9 polypeptide, can comprise one or more of the following domains: a RuvC-like domain and an HNH-like domain. In an embodiment, a Cas9 molecule or Cas9 polypeptide is an eaCas9 molecule or eaCas9 polypeptide and the eaCas9 molecule or eaCas9 polypeptide comprises a RuvC-like domain, e.g., a RuvC-like domain described below, and/or an HNH-like domain, e.g., an HNH-like domain described below.

(619) (b) RuvC-Like Domains

(620) In an embodiment, a RuvC-like domain cleaves, a single strand, e.g., the non-complementary strand of the target nucleic acid molecule. The Cas9 molecule or Cas9 polypeptide can include more than one RuvC-like domain (e.g., one, two, three or more RuvC-like domains). In an embodiment, a RuvC-like domain is at least 5, 6, 7, 8 amino acids in length but not more than 20, 19, 18, 17, 16 or 15 amino acids in length. In an embodiment, the Cas9 molecule or Cas9 polypeptide comprises an N-terminal RuvC-like domain of about 10 to 20 amino acids, e.g., about 15 amino acids in length.

(621) (c) N-Terminal RuvC-Like Domains

(622) Some naturally occurring Cas9 molecules comprise more than one RuvC-like domain with cleavage being dependent on the N-terminal RuvC-like domain. Accordingly, Cas9 molecules or Cas9 polypeptide can comprise an N-terminal RuvC-like domain.

(623) (d) Additional RuvC-Like Domains

(624) In addition to the N-terminal RuvC-like domain, the Cas9 molecule or Cas9 polypeptide, e.g., an eaCas9 molecule or eaCas9 polypeptide, can comprise one or more additional RuvC-like domains. In an embodiment, the Cas9 molecule or Cas9 polypeptide can comprise two additional RuvC-like domains Preferably, the additional RuvC-like domain is at least 5 amino acids in length and, e.g., less than 15 amino acids in length, e.g., 5 to 10 amino acids in length, e.g., 8 amino acids in length.

(625) (e) HNH-Like Domains

(626) In an embodiment, an HNH-like domain cleaves a single stranded complementary domain, e.g., a complementary strand of a double stranded nucleic acid molecule. In an embodiment, an HNH-like domain is at least 15, 20, 25 amino acids in length but not more than 40, 35 or 30 amino acids in length, e.g., 20 to 35 amino acids in length, e.g., 25 to 30 amino acids in length. Exemplary HNH-like domains are described below.

(627) In an embodiment, the HNH-like domain is cleavage competent.

(628) In an embodiment, the HNH-like domain is cleavage incompetent.

(629) (2) Cas9 Activities

(630) (a) Nuclease and Helicase Activifies

(631) In an embodiment, the Cas9 molecule or Cas9 polypeptide is capable of cleaving a target nucleic acid molecule. Typically wild type Cas9 molecules cleave both strands of a target nucleic acid molecule. Cas9 molecules and Cas9 polypeptides can be engineered to alter nuclease cleavage (or other properties), e.g., to provide a Cas9 molecule or Cas9 polypeptide which is a nickase, or which lacks the ability to cleave target nucleic acid. A Cas9 molecule or Cas9 polypeptide that is capable of cleaving a target nucleic acid molecule is referred to herein as an eaCas9 molecule or eaCas9 polypeptide

(632) In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises one or more of the following activities: a nickase activity, i.e., the ability to cleave a single strand, e.g., the non-complementary strand or the complementary strand, of a nucleic acid molecule; a double stranded nuclease activity, i.e., the ability to cleave both strands of a double stranded nucleic acid and create a double stranded break, which in an embodiment is the presence of two nickase activities; an endonuclease activity; an exonuclease activity; and a helicase activity, i.e., the ability to unwind the helical structure of a double stranded nucleic acid.

(633) In an embodiment, an enzymatically active or eaCas9 molecule or eaCas9 polypeptide cleaves both strands and results in a double stranded break. In an embodiment, an eaCas9 molecule cleaves only one strand, e.g., the strand to which the gRNA hybridizes to, or the strand complementary to the strand the gRNA hybridizes with. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises cleavage activity associated with an HNH-like domain. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises cleavage activity associated with an N-terminal RuvC-like domain. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises cleavage activity associated with an HNH-like domain and cleavage activity associated with an N-terminal RuvC-like domain. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises an active, or cleavage competent, HNH-like domain and an inactive, or cleavage incompetent, N-terminal RuvC-like domain. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises an inactive, or cleavage incompetent, HNH-like domain and an active, or cleavage competent, N-terminal RuvC-like domain.

(634) Some Cas9 molecules or Cas9 polypeptides have the ability to interact with a gRNA molecule, and in conjunction with the gRNA molecule localize to a core target domain, but are incapable of cleaving the target nucleic acid, or incapable of cleaving at efficient rates. Cas9 molecules having no, or no substantial, cleavage activity are referred to herein as an eiCas9 molecule or eiCas9 polypeptide. For example, an eiCas9 molecule or eiCas9 polypeptide can lack cleavage activity or have substantially less, e.g., less than 20, 10, 5, 1 or 0.1% of the cleavage activity of a reference Cas9 molecule or eiCas9 polypeptide, as measured by an assay described herein.

(635) (b) Targeting and PAMs

(636) A Cas9 molecule or Cas9 polypeptide, is a polypeptide that can interact with a guide RNA (gRNA) molecule and, in concert with the gRNA molecule, localizes to a site which comprises a target domain and a PAM sequence.

(637) In an embodiment, the ability of an eaCas9 molecule or eaCas9 polypeptide to interact with and cleave a target nucleic acid is PAM sequence dependent. A PAM sequence is a sequence in the target nucleic acid. In an embodiment, cleavage of the target nucleic acid occurs upstream from the PAM sequence. EaCas9 molecules from different bacterial species can recognize different sequence motifs (e.g., PAM sequences). In an embodiment, an eaCas9 molecule of S. pyogenes recognizes the sequence motif NGG, NAG, NGA and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. See, e.g., Mali et al., SCIENCE 2013; 339(6121): 823-826. In an embodiment, an eaCas9 molecule of S. thermophilus recognizes the sequence motif NGGNG and/or NNAGAAW (W=A or T) and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from these sequences. See, e.g., Horvath et al., SCIENCE 2010; 327(5962):167-170, and Deveau et al., J Bacteriol 2008; 190(4): 1390-1400. In an embodiment, an eaCas9 molecule of S. mutans recognizes the sequence motif NGG and/or NAAR (R=A or G)) and directs cleavage of a core target nucleic acid sequence 1 to 10, e.g., 3 to 5 base pairs, upstream from this sequence. See, e.g., Deveau et al., J Bacteriol 2008; 190(4): 1390-1400. In an embodiment, an eaCas9 molecule of S. aureus recognizes the sequence motif NNGRR (R=A or G) and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. In an embodiment, an eaCas9 molecule of S. aureus recognizes the sequence motif NNGRRT (R=A or G) and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. In an embodiment, an eaCas9 molecule of S. aureus recognizes the sequence motif NNGRRV (R=A or G) and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. In an embodiment, an eaCas9 molecule of N. meningitidis recognizes the sequence motif NNNNGATT or NNNGCTT (R=A or G, V=A, G or C and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. See, e.g., Hou et al., PNAS EARLY EDITION 2013, 1-6. The ability of a Cas9 molecule to recognize a PAM sequence can be determined, e.g., using a transformation assay described in Jinek et al., SCIENCE 2012 337:816. In the aforementioned embodiments, N can be any nucleotide residue, e.g., any of A, G, C or T.

(638) As is discussed herein, Cas9 molecules can be engineered to alter the PAM specificity of the Cas9 molecule.

(639) Exemplary naturally occurring Cas9 molecules are described in Chylinski et al., RNA Biology 2013 10:5, 727-737. Such Cas9 molecules include Cas9 molecules of a cluster 1-78 bacterial family.

(640) Exemplary naturally occurring Cas9 molecules include a Cas9 molecule of a cluster 1 bacterial family.

(3) Engineered or Altered Cas9 Molecules and Cas9 Polypeptides

(651) Cas9 molecules and Cas9 polypeptides described herein, e.g., naturally occurring Cas9 molecules, can possess any of a number of properties, including: nickase activity, nuclease activity (e.g., endonuclease and/or exonuclease activity); helicase activity; the ability to associate functionally with a gRNA molecule; and the ability to target (or localize to) a site on a nucleic acid (e.g., PAM recognition and specificity). In an embodiment, a Cas9 molecule or Cas9 polypeptide can include all or a subset of these properties. In typical embodiments, a Cas9 molecule or Cas9 polypeptide has the ability to interact with a gRNA molecule and, in concert with the gRNA molecule, localize to a site in a nucleic acid. Other activities, e.g., PAM specificity, cleavage activity, or helicase activity can vary more widely in Cas9 molecules and Cas9 polypeptides.

(652) Cas9 molecules include engineered Cas9 molecules and engineered Cas9 polypeptides (engineered, as used in this context, means merely that the Cas9 molecule or Cas9 polypeptide differs from a reference sequences, and implies no process or origin limitation). An engineered Cas9 molecule or Cas9 polypeptide can comprise altered enzymatic properties, e.g., altered nuclease activity, (as compared with a naturally occurring or other reference Cas9 molecule) or altered helicase activity. As discussed herein, an engineered Cas9 molecule or Cas9 polypeptide can have nickase activity (as opposed to double strand nuclease activity). In an embodiment an engineered Cas9 molecule or Cas9 polypeptide can have an alteration that alters its size, e.g., a deletion of amino acid sequence that reduces its size, e.g., without significant effect on one or more, or any Cas9 activity. In an embodiment, an engineered Cas9 molecule or Cas9 polypeptide can comprise an alteration that affects PAM recognition. E.g., an engineered Cas9 molecule can be altered to recognize a PAM sequence other than that recognized by the endogenous wild-type PI domain. In an embodiment a Cas9 molecule or Cas9 polypeptide can differ in sequence from a naturally occurring Cas9 molecule but not have significant alteration in one or more Cas9 activities.

(653) Cas9 molecules or Cas9 polypeptides with desired properties can be made in a number of ways, e.g., by alteration of a parental, e.g., naturally occurring, Cas9 molecules or Cas9 polypeptides, to provide an altered Cas9 molecule or Cas9 polypeptide having a desired property. For example, one or more mutations or differences relative to a parental Cas9 molecule, e.g., a naturally occurring or engineered Cas9 molecule, can be introduced. Such mutations and differences comprise: substitutions (e.g., conservative substitutions or substitutions of non-essential amino acids); insertions; or deletions. In an embodiment, a Cas9 molecule or Cas9 polypeptide can comprises one or more mutations or differences, e.g., at least 1, 2, 3, 4, 5, 10, 15, 20, 30, 40 or 50 mutations but less than 200, 100, or 80 mutations relative to a reference, e.g., a parental, Cas9 molecule.

(654) In an embodiment, a mutation or mutations do not have a substantial effect on a Cas9 activity, e.g. a Cas9 activity described herein. In an embodiment, a mutation or mutations have a substantial effect on a Cas9 activity, e.g. a Cas9 activity described herein.

An exemplary inactive, or cleavage incompetent N-terminal RuvC-like domain can have a mutation of an aspartic acid in an N-terminal RuvC-like domain, e.g., an aspartic acid at position 9 of the consensus sequence disclosed in FIGS. 15A-15G or an aspartic acid at position 10 of SEQ ID NO:1336, e.g., can be substituted with an alanine. In an embodiment, the eaCas9 molecule or eaCas9 polypeptide differs from wild type in the N-terminal RuvC-like domain and does not cleave the target nucleic acid, or cleaves with significantly less efficiency, e.g., less than 20, 10, 5, 1 or 0.1% of the cleavage activity of a reference Cas9 molecule, e.g., as measured by an assay described herein. The reference Cas9 molecule can by a naturally occurring unmodified Cas9 molecule, e.g., a naturally occurring Cas9 molecule such as a Cas9 molecule of S. pyogenes, or S. thermophilus.

The reference Cas9 molecule can by a naturally occurring unmodified Cas9 molecule, e.g., a naturally occurring Cas9 molecule such as a Cas9 molecule of S. pyogenes, or S. thermophilus. In an embodiment, the reference Cas9 molecule is the naturally occurring Cas9 molecule having the closest sequence identity or homology.

(659) In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises an inactive, or cleavage incompetent, HNH domain and an active, or cleavage competent, N-terminal RuvC-like domain. Exemplary inactive, or cleavage incompetent HNH-like domains can have a mutation at one or more of: a histidine in an HNH-like domain, e.g., a histidine shown at position 856 of FIGS. 15A-15G, e.g., can be substituted with an alanine; and one or more asparagines in an HNH-like domain, e.g., an asparagine shown at position 870 of FIGS. 15A-15G and/or at position 879 of FIGS. 15A-15G, e.g., can be substituted with an alanine. In an embodiment, the eaCas9 differs from wild type in the HNH-like domain and does not cleave the target nucleic acid, or cleaves with significantly less efficiency, e.g., less than 20, 10, 5, 1 or 0.1% of the cleavage activity of a reference Cas9 molecule, e.g., as measured by an assay described herein. The reference Cas9 molecule can by a naturally occurring unmodified Cas9 molecule, e.g., a naturally occurring Cas9 molecule such as a Cas9 molecule of S. pyogenes, or S. thermophilus. In an embodiment, the reference Cas9 molecule is the naturally occurring Cas9 molecule having the closest sequence identity or homology.

(c) Alterations in the Ability to Cleave One or Both Strands of a Target Nucleic Acid

(660) In an embodiment, exemplary Cas9 activities comprise one or more of PAM specificity, cleavage activity, and helicase activity. A mutation(s) can be present, e.g., in: one or more RuvC-like domain, e.g., an N-terminal RuvC-like domain; an HNH-like domain; a region outside the RuvC-like domains and the HNH-like domain. In some embodiments, a mutation(s) is present in a RuvC-like domain, e.g., an N-terminal RuvC-like. In some embodiments, a mutation(s) is present in an HNH-like domain. In some embodiments, mutations are present in both a RuvC-like domain, e.g., an N-terminal RuvC-like domain, and an HNH-like domain.

(661) Exemplary mutations that may be made in the RuvC domain or HNH domain with reference to the S. pyogenes sequence include: D10A, E762A, H840A, N854A, N863A and/or D986A.

(663) Whether or not a particular sequence, e.g., a substitution, may affect one or more activity, such as targeting activity, cleavage activity, etc., can be evaluated or predicted, e.g., by evaluating whether the mutation is conservative or by the method described in Section IV. In an embodiment, a non-essential amino acid residue, as used in the context of a Cas9 molecule, is a residue that can be altered from the wild-type sequence of a Cas9 molecule, e.g., a naturally occurring Cas9 molecule, e.g., an eaCas9 molecule, without abolishing or more preferably, without substantially altering a Cas9 activity (e.g., cleavage activity), whereas changing an essential amino acid residue results in a substantial loss of activity (e.g., cleavage activity).

(664) In an embodiment, a Cas9 molecule or Cas9 polypeptide comprises a cleavage property that differs from naturally occurring Cas9 molecules, e.g., that differs from the naturally occurring Cas9 molecule having the closest homology. For example, a Cas9 molecule or Cas9 polypeptide can differ from naturally occurring Cas9 molecules, e.g., a Cas9 molecule of S. aureus, S. pyogenes, or C. jejuni as follows: its ability to modulate, e.g., decreased or increased, cleavage of a double stranded break (endonuclease and/or exonuclease activity), e.g., as compared to a naturally occurring Cas9 molecule (e.g., a Cas9 molecule of S. aureus, S. pyogenes, or C. jejuni); its ability to modulate, e.g., decreased or increased, cleavage of a single strand of a nucleic acid, e.g., a non-complementary strand of a nucleic acid molecule or a complementary strand of a nucleic acid molecule (nickase activity), e.g., as compared to a naturally occurring Cas9 molecule (e.g., a Cas9 molecule of S. aureus, S. pyogenes, or C. jejuni); or the ability to cleave a nucleic acid molecule, e.g., a double stranded or single stranded nucleic acid molecule, can be eliminated.

The reference Cas9 molecule can be a naturally occurring unmodified Cas9 molecule, e.g., a naturally occurring Cas9 molecule such as a Cas9 molecule of S. pyogenes, S. thermophilus, S. aureus, C. jejuni or N. meningitidis. In an embodiment, the reference Cas9 molecule is the naturally occurring Cas9 molecule having the closest sequence identity or homology.

(681) the sequence corresponding to the residues identified by - in the consensus sequence disclosed in FIGS. 15A-15G differ at no more than 5, 10, 15, 20, 25, 30, 35, 40, 45, 55, or 60% of the - residues from the corresponding sequence of naturally occurring Cas9 molecule, e.g., an S. mutans Cas9 molecule.

(682) In an embodiment, the altered Cas9 molecule or Cas9 polypeptide is an eaCas9 molecule or eaCas9 polypeptide comprising the fixed amino acid residues of L. innocula shown in the consensus sequence disclosed in FIGS. 15A-15G, and has one or more amino acids that differ from the amino acid sequence of L. innocula (e.g., has a substitution) at one or more residue (e.g., 2, 3, 5, 10, 15, 20, 30, 50, 70, 80, 90, 100, 200 amino acid residues) represented by an - in the consensus sequence disclosed in FIGS. 15A-15G.

(683) In an embodiment, the altered Cas9 molecule or Cas9 polypeptide comprises a sequence in which:

(684) the sequence corresponding to the fixed sequence of the consensus sequence disclosed in FIGS. 15A-15G differs at no more than 1, 2, 3, 4, 5, 10, 15, or 20% of the fixed residues in the consensus sequence disclosed in FIGS. 15A-15G;

(685) the sequence corresponding to the residues identified by * in the consensus sequence disclosed in FIGS. 15A-15G differ at no more than 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, or 40% of the * residues from the corresponding sequence of naturally occurring Cas9 molecule, e.g., an L. innocula Cas9 molecule; and,

(686) the sequence corresponding to the residues identified by - in the consensus sequence disclosed in FIGS. 15A-15G differ at no more than 5, 10, 15, 20, 25, 30, 35, 40, 45, 55, or 60% of the - residues from the corresponding sequence of naturally occurring Cas9 molecule, e.g., an L. innocula Cas9 molecule.

(687) In an embodiment, the altered Cas9 molecule or Cas9 polypeptide, e.g., an eaCas9 molecule, can be a fusion, e.g., of two of more different Cas9 molecules or Cas9 polypeptides, e.g., of two or more naturally occurring Cas9 molecules of different species. For example, a fragment of a naturally occurring Cas9 molecule of one species can be fused to a fragment of a Cas9 molecule of a second species. As an example, a fragment of Cas9 molecule of S. pyogenes comprising an N-terminal RuvC-like domain can be fused to a fragment of Cas9 molecule of a species other than S. pyogenes (e.g., S. thermophilus) comprising an HNH-like domain.

(d) Cas9 Molecules With Altered PAM Recognition or No PAM Recognition

(688) Naturally occurring Cas9 molecules can recognize specific PAM sequences, for example the PAM recognition sequences described above for, e.g., S. pyogenes, S. thermophilus, S. mutans, S. aureus and N. meningitidis.

(689) In an embodiment, a Cas9 molecule or Cas9 polypeptide has the same PAM specificities as a naturally occurring Cas9 molecule. In other embodiments, a Cas9 molecule or Cas9 polypeptide has a PAM specificity not associated with a naturally occurring Cas9 molecule, or a PAM specificity not associated with the naturally occurring Cas9 molecule to which it has the closest sequence homology. For example, a naturally occurring Cas9 molecule can be altered, e.g., to alter PAM recognition, e.g., to alter the PAM sequence that the Cas9 molecule or Cas9 polypeptide recognizes to decrease off target sites and/or improve specificity; or eliminate a PAM recognition requirement. In an embodiment, a Cas9 molecule can be altered, e.g., to increase length of PAM recognition sequence and/or improve Cas9 specificity to high level of identity, e.g., to decrease off target sites and increase specificity. In an embodiment, the length of the PAM recognition sequence is at least 4, 5, 6, 7, 8, 9, 10 or 15 amino acids in length.

(690) Cas9 molecules or Cas9 polypeptides that recognize different PAM sequences and/or have reduced off-target activity can be generated using directed evolution. Exemplary methods and systems that can be used for directed evolution of Cas9 molecules are described, e.g., in Esvelt et al. Nature 2011, 472(7344): 499-503. Candidate Cas9 molecules can be evaluated.

For example, the synthetic nucleic acid molecule can be chemically modified. In an embodiment, the Cas9 mRNA has one or more (e.g., all of the following properties: it is capped, polyadenylated, substituted with 5-methylcytidine and/or pseudouridine.

(694) In addition, or alternatively, the synthetic nucleic acid sequence can be codon optimized, e.g., at least one non-common codon or less-common codon has been replaced by a common codon. For example, the synthetic nucleic acid can direct the synthesis of an optimized messenger mRNA, e.g., optimized for expression in a mammalian expression system, e.g., described herein.

(695) In addition, or alternatively, a nucleic acid encoding a Cas9 molecule or Cas9 polypeptide may comprise a nuclear localization sequence (NLS). Nuclear localization sequences are known in the art.

(696) SEQ ID NO:1337 is an exemplary codon optimized nucleic acid sequence encoding a Cas9 molecule of S. pyogenes. SEQ ID NO:1338 is the corresponding amino acid sequence of a S. pyogenes Cas9 molecule. SEQ ID NO:1339 is an exemplary codon optimized nucleic acid sequence encoding a Cas9 molecule of N. meningitidis. SEQ ID NO:1340 is the corresponding amino acid sequence of a N. meningitidis Cas9 molecule. SEQ ID NO:1341 is an exemplary codon optimized nucleic acid sequence encoding a Cas9 molecule of S. aureus Cas9. SEQ ID NO:1342 is an amino acid sequence of a S. aureus Cas9 molecule.

(697) If any of the above Cas9 sequences are fused with a peptide or polypeptide at the C-terminus, it is understood that the stop codon will be removed.

c) Cpf1

(700) In some embodiments, the guide RNA or gRNA promotes the specific association targeting of an RNA-guided nuclease such as a Cas9 or a Cpf1 to a target sequence such as a genomic or episomal sequence in a cell. In general, gRNAs can be unimolecular (comprising a single RNA molecule, and referred to alternatively as chimeric), or modular (comprising more than one, and typically two, separate RNA molecules, such as a crRNA and a tracrRNA, which are usually associated with one another, for instance by duplexing). gRNAs and their component parts are described throughout the literature, for instance in Briner et al. (Molecular Cell 56(2), 333-339, Oct. 23, 2014 (Briner), which is incorporated by reference), and in Cotta-Ramusino.

(701) Guide RNAs, whether unimolecular or modular, generally include a targeting domain that is fully or partially complementary to a target, and are typically 10-30 nucleotides in length, and in certain embodiments are 16-24 nucleotides in length (for instance, 16, 17, 18, 19, 20, 21, 22, 23 or 24 nucleotides in length). In some aspects, the targeting domains are at or near the 5 terminus of the gRNA in the case of a Cas9 gRNA, and at or near the 3 terminus in the case of a Cpf1 gRNA. While the foregoing description has focused on gRNAs for use with Cas9, it should be appreciated that other RNA-guided nucleases have been (or may in the future be) discovered or invented which utilize gRNAs that differ in some ways from those described to this point. For instance, Cpf1 (CRISPR from Prevotella and Franciscella 1) is a recently discovered RNA-guided nuclease that does not require a tracrRNA to function. (Zetsche et al., 2015, Cell 163, 759-771 Oct. 22, 2015 (Zetsche I), incorporated by reference herein). A gRNA for use in a Cpf1 genome editing system generally includes a targeting domain and a complementarity domain (alternately referred to as a handle). It should also be noted that, in gRNAs for use with Cpf1, the targeting domain is usually present at or near the 3 end, rather than the 5 end as described above in connection with Cas9 gRNAs (the handle is at or near the 5 end of a Cpf1 gRNA).

(702) Although structural differences may exist between gRNAs from different prokaryotic species, or between Cpf1 and Cas9 gRNAs, the principles by which gRNAs operate are generally consistent. Because of this consistency of operation, gRNAs can be defined, in broad terms, by their targeting domain sequences, and skilled artisans will appreciate that a given targeting domain sequence can be incorporated in any suitable gRNA, including a unimolecular or chimeric gRNA, or a gRNA that includes one or more chemical modifications and/or sequential modifications (substitutions, additional nucleotides, truncations, etc.). Thus, in some aspects in this disclosure, gRNAs may be described solely in terms of their targeting domain sequences.

(703) More generally, some aspects of the present disclosure relate to systems, methods and compositions that can be implemented using multiple RNA-guided nucleases. Unless otherwise specified, the term gRNA should be understood to encompass any suitable gRNA that can be used with any RNA-guided nuclease, and not only those gRNAs that are compatible with a particular species of Cas9 or Cpf1. By way of illustration, the term gRNA can, in certain embodiments, include a gRNA for use with any RNA-guided nuclease occurring in a Class 2 CRISPR system, such as a type II or type V or CRISPR system, or an RNA-guided nuclease derived or adapted therefrom.

(704) Certain exemplary modifications discussed in this section can be included at any position within a gRNA sequence including, without limitation at or near the 5 end (e.g., within 1-10, 1-5, or 1-2 nucleotides of the 5 end) and/or at or near the 3 end (e.g., within 1-10, 1-5, or 1-2 nucleotides of the 3 end). In some cases, modifications are positioned within functional motifs, such as the repeat-anti-repeat duplex of a Cas9 gRNA, a stem loop structure of a Cas9 or Cpf1 gRNA, and/or a targeting domain of a gRNA.

(705) RNA-guided nucleases include, but are not limited to, naturally-occurring Class 2 CRISPR nucleases such as Cas9, and Cpf1, as well as other nucleases derived or obtained therefrom. In functional terms, RNA-guided nucleases are defined as those nucleases that: (a) interact with (e.g. complex with) a gRNA; and (b) together with the gRNA, associate with, and optionally cleave or modify, a target region of a DNA that includes (i) a sequence complementary to the targeting domain of the gRNA and, optionally, (ii) an additional sequence referred to as a protospacer adjacent motif, or PAM, which is described in greater detail below. As the following examples will illustrate, RNA-guided nucleases can be defined, in broad terms, by their PAM specificity and cleavage activity, even though variations may exist between individual RNA-guided nucleases that share the same PAM specificity or cleavage activity. Skilled artisans will appreciate that some aspects of the present disclosure relate to systems, methods and compositions that can be implemented using any suitable RNA-guided nuclease having a certain PAM specificity and/or cleavage activity. For this reason, unless otherwise specified, the term RNA-guided nuclease should be understood as a generic term, and not limited to any particular type (e.g. Cas9 vs. Cpf1), species (e.g. S. pyogenes vs. S. aureus) or variation (e.g full-length vs. truncated or split; naturally-occurring PAM specificity vs. engineered PAM specificity, etc.) of RNA-guided nuclease.

(706) In addition to recognizing specific sequential orientations of PAMs and protospacers, RNA-guided nucleases in some embodiments can also recognize specific PAM sequences. S. aureus Cas9, for instance, generally recognizes a PAM sequence of NNGRRT or NNGRRV, wherein the N residues are immediately 3 of the region recognized by the gRNA targeting domain. S. pyogenes Cas9 generally recognizes NGG PAM sequences. And F. novicida Cpf1 generally recognizes a TTN PAM sequence.

(707) The crystal structure of Acidaminococcus sp. Cpf1 in complex with crRNA and a double-stranded (ds) DNA target including a TTTN PAM sequence has been solved by Yamano et al. (Cell. 2016 May 5; 165(4): 949-962 (Yamano), incorporated by reference herein). Cpf1, like Cas9, has two lobes: a REC (recognition) lobe, and a NUC (nuclease) lobe. The REC lobe includes REC1 and REC2 domains, which lack similarity to any known protein structures. The NUC lobe, meanwhile, includes three RuvC domains (RuvC-I, -II and -III) and a BH domain. However, in contrast to Cas9, the Cpf1 REC lobe lacks an HNH domain, and includes other domains that also lack similarity to known protein structures: a structurally unique PI domain, three Wedge (WED) domains (WED-I, -II and -III), and a nuclease (Nuc) domain.

(708) While Cas9 and Cpf1 share similarities in structure and function, it should be appreciated that certain Cpf1 activities are mediated by structural domains that are not analogous to any Cas9 domains. For instance, cleavage of the complementary strand of the target DNA appears to be mediated by the Nuc domain, which differs sequentially and spatially from the HNH domain of Cas9. Additionally, the non-targeting portion of Cpf1 gRNA (the handle) adopts a pseudoknot structure, rather than a stem loop structure formed by the repeat:antirepeat duplex in Cas9 gRNAs.

(709) Nucleic acids encoding RNA-guided nucleases, e.g., Cas9, Cpf1 or functional fragments thereof, are provided herein. Exemplary nucleic acids encoding RNA-guided nucleases have been described previously (see, e.g., Cong 2013; Wang 2013; Mali 2013; Jinek 2012).

3. Genome Editing Methods and Methods of Delivery

a) Genome Editing Approaches

(710) In general, it is to be understood that the alteration of any gene according to the methods described herein can be mediated by any mechanism and that any methods are not limited to a particular mechanism. Exemplary mechanisms that can be associated with the alteration of a gene include, but are not limited to, non-homologous end joining (e.g., classical or alternative), microhomology-mediated end joining (MMEJ), homology-directed repair (e.g., endogenous donor template mediated), synthesis dependent strand annealing (SDSA), single strand annealing, single strand invasion, single strand break repair (SSBR), mismatch repair (MMR), base excision repair (BER), Interstrand Crosslink (ICL) Translesion synthesis (TLS), or Error-free postreplication repair (PRR). Described herein are exemplary methods for targeted knockout of one or both alleles of one or all of TRAC, TRBC1 and/or TRBC2.

(1) NHEJ Approaches for Gene Targeting

(711) As described herein, nuclease-induced non-homologous end joining (NHEJ) can be used to target gene-specific knockouts. Nuclease-induced NHEJ can also be used to remove (e.g., delete) sequence insertions in a gene of interest.

(712) While not wishing to be bound by theory, it is believed that, in an embodiment, the genomic alterations associated with the methods described herein rely on nuclease-induced NHEJ and the error-prone nature of the NHEJ repair pathway. NHEJ repairs a double-strand break in the DNA by joining together the two ends; however, generally, the original sequence is restored only if two compatible ends, exactly as they were formed by the double-strand break, are perfectly ligated. The DNA ends of the double-strand break are frequently the subject of enzymatic processing, resulting in the addition or removal of nucleotides, at one or both strands, prior to rejoining of the ends. This results in the presence of insertion and/or deletion (indel) mutations in the DNA sequence at the site of the NHEJ repair. Two-thirds of these mutations typically alter the reading frame and, therefore, produce a non-functional protein. Additionally, mutations that maintain the reading frame, but which insert or delete a significant amount of sequence, can destroy functionality of the protein. This is locus dependent as mutations in critical functional domains are likely less tolerable than mutations in non-critical regions of the protein. The indel mutations generated by NHEJ are unpredictable in nature; however, at a given break site certain indel sequences are favored and are over represented in the population, likely due to small regions of microhomology. The lengths of deletions can vary widely; most commonly in the 1-50 bp range, but they can easily reach greater than 100-200 bp. Insertions tend to be shorter and often include short duplications of the sequence immediately surrounding the break site. However, it is possible to obtain large insertions, and in these cases, the inserted sequence has often been traced to other regions of the genome or to plasmid DNA present in the cells.

(713) Because NHEJ is a mutagenic process, it can also be used to delete small sequence motifs as long as the generation of a specific final sequence is not required. If a double-strand break is targeted near to a short target sequence, the deletion mutations caused by the NHEJ repair often span, and therefore remove, the unwanted nucleotides. For the deletion of larger DNA segments, introducing two double-strand breaks, one on each side of the sequence, can result in NHEJ between the ends with removal of the entire intervening sequence. In some embodiments, a pair of gRNAs can be used to introduce two double-strand breaks, resulting in a deletion of intervening sequences between the two breaks.

(714) Both of these approaches can be used to delete specific DNA sequences; however, the error-prone nature of NHEJ may still produce indel mutations at the site of repair.

(715) Both double strand cleaving eaCas9 molecules and single strand, or nickase, eaCas9 molecules can be used in the methods and compositions described herein to generate NHEJ-mediated indels. NHEJ-mediated indels targeted to the gene, e.g., a coding region, e.g., an early coding region of a gene, of interest can be used to knockout (i.e., eliminate expression of) a gene of interest. For example, early coding region of a gene of interest includes sequence immediately following a transcription start site, within a first exon of the coding sequence, or within 500 bp of the transcription start site (e.g., less than 500, 450, 400, 350, 300, 250, 200, 150, 100 or 50 bp).

(716) In an embodiment, NHEJ-mediated indels are introduced into one or more T-cell expressed genes, such as TRAC, TRBC1 and/or TRBC2. Individual gRNAs or gRNA pairs targeting the gene are provided together with the Cas9 double-stranded nuclease or single-stranded nickase.

(2) Placement of Double Strand or Single Strand Breaks Relative to the Target Position

(717) In an embodiment, in which a gRNA and Cas9 nuclease generate a double strand break for the purpose of inducing NHEJ-mediated indels, a gRNA, e.g., a unimolecular (or chimeric) or modular gRNA molecule, is configured to position one double-strand break in close proximity to a nucleotide of the target position. In an embodiment, the cleavage site is between 0-30 bp away from the target position (e.g., less than 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1 bp from the target position).

(718) In an embodiment, in which two gRNAs complexing with Cas9 nickases induce two single strand breaks for the purpose of inducing NHEJ-mediated indels, two gRNAs, e.g., independently, unimolecular (or chimeric) or modular gRNA, are configured to position two single-strand breaks to provide for NHEJ repair a nucleotide of the target position. In an embodiment, the gRNAs are configured to position cuts at the same position, or within a few nucleotides of one another, on different strands, essentially mimicking a double strand break. In an embodiment, the closer nick is between 0-30 bp away from the target position (e.g., less than 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1 bp from the target position), and the two nicks are within 25-55 bp of each other (e.g., between 25 to 50, 25 to 45, 25 to 40, 25 to 35, 25 to 30, 50 to 55, 45 to 55, 40 to 55, 35 to 55, 30 to 55, 30 to 50, 35 to 50, 40 to 50, 45 to 50, 35 to 45, or 40 to 45 bp) and no more than 100 bp away from each other (e.g., no more than 90, 80, 70, 60, 50, 40, 30, 20 or 10 bp). In an embodiment, the gRNAs are configured to place a single strand break on either side of a nucleotide of the target position.

(719) Both double strand cleaving eaCas9 molecules and single strand, or nickase, eaCas9 molecules can be used in the methods and compositions described herein to generate breaks both sides of a target position. Double strand or paired single strand breaks may be generated on both sides of a target position to remove the nucleic acid sequence between the two cuts (e.g., the region between the two breaks in deleted). In an embodiment, two gRNAs, e.g., independently, unimolecular (or chimeric) or modular gRNA, are configured to position a double-strand break on both sides of a target position. In an alternate embodiment, three gRNAs, e.g., independently, unimolecular (or chimeric) or modular gRNA, are configured to position a double strand break (i.e., one gRNA complexes with a cas9 nuclease) and two single strand breaks or paired single stranded breaks (i.e., two gRNAs complex with Cas9 nickases) on either side of the target position. In another embodiment, four gRNAs, e.g., independently, unimolecular (or chimeric) or modular gRNA, are configured to generate two pairs of single stranded breaks (i.e., two pairs of two gRNAs complex with Cas9 nickases) on either side of the target position. The double strand break(s) or the closer of the two single strand nicks in a pair will ideally be within 0-500 bp of the target position (e.g., no more than 450, 400, 350, 300, 250, 200, 150, 100, 50 or 25 bp from the target position). When nickases are used, the two nicks in a pair are within 25-55 bp of each other (e.g., between 25 to 50, 25 to 45, 25 to 40, 25 to 35, 25 to 30, 50 to 55, 45 to 55, 40 to 55, 35 to 55, 30 to 55, 30 to 50, 35 to 50, 40 to 50, 45 to 50, 35 to 45, or 40 to 45 bp) and no more than 100 bp away from each other (e.g., no more than 90, 80, 70, 60, 50, 40, 30, 20 or 10 bp).

(3) Targeted Knockdown

(720) Unlike CRISPR/Cas-mediated gene knockout, which permanently eliminates or reduces expression by mutating the gene at the DNA level, CRISPR/Cas knockdown allows for temporary reduction of gene expression through the use of artificial transcription factors. Mutating key residues in both DNA cleavage domains of the Cas9 protein (e.g., the D10A and H840A mutations) results in the generation of a catalytically inactive Cas9 (eiCas9 which is also known as dead Cas9 or dCas9). A catalytically inactive Cas9 complexes with a gRNA and localizes to the DNA sequence specified by that gRNA's targeting domain, however, it does not cleave the target DNA. Fusion of the dCas9 to an effector domain, e.g., a transcription repression domain, enables recruitment of the effector to any DNA site specified by the gRNA. While it has been shown that the eiCas9 itself can block transcription when recruited to early regions in the coding sequence, more robust repression can be achieved by fusing a transcriptional repression domain (for example KRAB, SID or ERD) to the Cas9 and recruiting it to the promoter region of a gene. It is likely that targeting DNAseI hypersensitive regions of the promoter may yield more efficient gene repression or activation because these regions are more likely to be accessible to the Cas9 protein and are also more likely to harbor sites for endogenous transcription factors. Especially for gene repression, it is contemplated herein that blocking the binding site of an endogenous transcription factor would aid in downregulating gene expression. In another embodiment, an eiCas9 can be fused to a chromatin modifying protein. Altering chromatin status can result in decreased expression of the target gene.

(721) In an embodiment, a gRNA molecule can be targeted to a known transcription response elements (e.g., promoters, enhancers, etc.), a known upstream activating sequences (UAS), and/or sequences of unknown or known function that are suspected of being able to control expression of the target DNA.

(722) In an embodiment, CRISPR/Cas-mediated gene knockdown can be used to reduce expression one or more T-cell expressed genes. In an embodiment, in which a eiCas9 or an eiCas9 fusion protein described herein is used to knockdown two T-cell expressed genes, e.g., any two or more of TRAC, TRBC1 and/or TRBC2 genes, individual gRNAs or gRNA pairs targeting both or all genes are provided together with the eiCas9 or eiCas9 fusion protein.

(4) Single-Strand Annealing

(723) Single strand annealing (SSA) is another DNA repair process that repairs a double-strand break between two repeat sequences present in a target nucleic acid. Repeat sequences utilized by the SSA pathway are generally greater than 30 nucleotides in length. Resection at the break ends occurs to reveal repeat sequences on both strands of the target nucleic acid. After resection, single strand overhangs containing the repeat sequences are coated with RPA protein to prevent the repeats sequences from inappropriate annealing, e.g., to themselves. RAD52 binds to and each of the repeat sequences on the overhangs and aligns the sequences to enable the annealing of the complementary repeat sequences. After annealing, the single-strand flaps of the overhangs are cleaved. New DNA synthesis fills in any gaps, and ligation restores the DNA duplex. As a result of the processing, the DNA sequence between the two repeats is deleted. The length of the deletion can depend on many factors including the location of the two repeats utilized, and the pathway or processivity of the resection.

(724) In contrast to HDR pathways, SSA does not require a template nucleic acid to alter or correct a target nucleic acid sequence. Instead, the complementary repeat sequence is utilized.

(5) Other DNA Repair Pathways

(a) SSBR (Single Strand Break Repair)

(725) Single-stranded breaks (SSB) in the genome are repaired by the SSBR pathway, which is a distinct mechanism from the DSB repair mechanisms discussed above. The SSBR pathway has four major stages: SSB detection, DNA end processing, DNA gap filling, and DNA ligation. A more detailed explanation is given in Caldecott, Nature Reviews Genetics 9, 619-631 (August 2008), and a summary is given here.

(726) In the first stage, when a SSB forms, PARP1 and/or PARP2 recognize the break and recruit repair machinery. The binding and activity of PARP1 at DNA breaks is transient and it seems to accelerate SSBr by promoting the focal accumulation or stability of SSBr protein complexes at the lesion. Arguably the most important of these SSBr proteins is XRCC1, which functions as a molecular scaffold that interacts with, stabilizes, and stimulates multiple enzymatic components of the SSBr process including the protein responsible for cleaning the DNA 3 and 5 ends. For instance, XRCC1 interacts with several proteins (DNA polymerase beta, PNK, and three nucleases, APE1, APTX, and APLF) that promote end processing. APE1 has endonuclease activity. APLF exhibits endonuclease and 3 to 5 exonuclease activities. APTX has endonuclease and 3 to 5 exonuclease activity.

(727) This end processing is an important stage of SSBR since the 3- and/or 5-termini of most, if not all, SSBs are damaged. End processing generally involves restoring a damaged 3-end to a hydroxylated state and and/or a damaged 5 end to a phosphate moiety, so that the ends become ligation-competent. Enzymes that can process damaged 3 termini include PNKP, APE1, and TDP1. Enzymes that can process damaged 5 termini include PNKP, DNA polymerase beta, and APTX. LIG3 (DNA ligase III) can also participate in end processing. Once the ends are cleaned, gap filling can occur.

(728) At the DNA gap filling stage, the proteins typically present are PARP1, DNA polymerase beta, XRCC1, FEN1 (flap endonculease 1), DNA polymerase delta/epsilon, PCNA, and LIG1. There are two ways of gap filling, the short patch repair and the long patch repair. Short patch repair involves the insertion of a single nucleotide that is missing. At some SSBs, gap filling might continue displacing two or more nucleotides (displacement of up to 12 bases have been reported). FEN1 is an endonuclease that removes the displaced 5-residues. Multiple DNA polymerases, including Pol ?, are involved in the repair of SSBs, with the choice of DNA polymerase influenced by the source and type of SSB.

(729) In the fourth stage, a DNA ligase such as LIG1 (Ligase I) or LIG3 (Ligase III) catalyzes joining of the ends. Short patch repair uses Ligase III and long patch repair uses Ligase I.

(730) Sometimes, SSBR is replication-coupled. This pathway can involve one or more of CtIP, MRN, ERCC1, and FEN1. Additional factors that may promote SSBR include: aPARP, PARP1, PARP2, PARG, XRCC1, DNA polymerase b, DNA polymerase d, DNA polymerase e, PCNA, LIG1, PNK, PNKP, APE1, APTX, APLF, TDP1, LIG3, FEN1, CtIP, MRN, and ERCC1.

(b) MMR (Mismatch Repair)

(731) Cells contain three excision repair pathways: MMR, BER, and NER. The excision repair pathways have a common feature in that they typically recognize a lesion on one strand of the DNA, then exo/endonucleaseases remove the lesion and leave a 1-30 nucleotide gap that is sub-sequentially filled in by DNA polymerase and finally sealed with ligase. A more complete picture is given in Li, Cell Research (2008) 18:85-98, and a summary is provided here.

(732) Mismatch repair (MMR) operates on mispaired DNA bases.

(733) The MSH2/6 or MSH2/3 complexes both have ATPases activity that plays an important role in mismatch recognition and the initiation of repair. MSH2/6 preferentially recognizes base-base mismatches and identifies mispairs of 1 or 2 nucleotides, while MSH2/3 preferentially recognizes larger ID mispairs.

(734) hMLH1 heterodimerizes with hPMS2 to form hMutLa which possesses an ATPase activity and is important for multiple steps of MMR. It possesses a PCNA/replication factor C (RFC)-dependent endonuclease activity which plays an important role in 3 nick-directed MMR involving EXO1. (EXO1 is a participant in both HR and MMR.) It regulates termination of mismatch-provoked excision. Ligase I is the relevant ligase for this pathway. Additional factors that may promote MMR include: EXO1, MSH2, MSH3, MSH6, MLH1, PMS2, MLH3, DNA Pol d, RPA, HMGB1, RFC, and DNA ligase I.

(c) Base Excision Repair (BER)

(735) The base excision repair (BER) pathway is active throughout the cell cycle; it is responsible primarily for removing small, non-helix-distorting base lesions from the genome. In contrast, the related Nucleotide Excision Repair pathway (discussed in the next section) repairs bulky helix-distorting lesions. A more detailed explanation is given in Caldecott, Nature Reviews Genetics 9, 619-631 (August 2008), and a summary is given here.

(736) Upon DNA base damage, base excision repair (BER) is initiated and the process can be simplified into five major steps: (a) removal of the damaged DNA base; (b) incision of the subsequent a basic site; (c) clean-up of the DNA ends; (d) insertion of the correct nucleotide into the repair gap; and (e) ligation of the remaining nick in the DNA backbone. These last steps are similar to the SSBR.

(737) In the first step, a damage-specific DNA glycosylase excises the damaged base through cleavage of the N-glycosidic bond linking the base to the sugar phosphate backbone. Then AP endonuclease-1 (APE1) or bifunctional DNA glycosylases with an associated lyase activity incised the phosphodiester backbone to create a DNA single strand break (SSB). The third step of BER involves cleaning-up of the DNA ends. The fourth step in BER is conducted by Pol ? that adds a new complementary nucleotide into the repair gap and in the final step XRCC1/Ligase III seals the remaining nick in the DNA backbone. This completes the short-patch BER pathway in which the majority (?80%) of damaged DNA bases are repaired. However, if the 5-ends in step 3 are resistant to end processing activity, following one nucleotide insertion by Pol ? there is then a polymerase switch to the replicative DNA polymerases, Pol ?/?, which then add ?2-8 more nucleotides into the DNA repair gap. This creates a 5-flap structure, which is recognized and excised by flap endonuclease-1 (FEN-1) in association with the processivity factor proliferating cell nuclear antigen (PCNA). DNA ligase I then seals the remaining nick in the DNA backbone and completes long-patch BER. Additional factors that may promote the BER pathway include: DNA glycosylase, APE1, Polb, Pold, Pole, XRCC1, Ligase III, FEN-1, PCNA, RECQL4, WRN, MYH, PNKP, and APTX.

(d) Nucleotide Excision Repair (NER)

(738) Nucleotide excision repair (NER) is an important excision mechanism that removes bulky helix-distorting lesions from DNA. Additional details about NER are given in Marteijn et al., Nature Reviews Molecular Cell Biology 15, 465-481 (2014), and a summary is given here. NER a broad pathway encompassing two smaller pathways: global genomic NER (GG-NER) and transcription coupled repair NER (TC-NER). GG-NER and TC-NER use different factors for recognizing DNA damage. However, they utilize the same machinery for lesion incision, repair, and ligation.

(739) Once damage is recognized, the cell removes a short single-stranded DNA segment that contains the lesion. Endonucleases XPF/ERCC1 and XPG (encoded by ERCC5) remove the lesion by cutting the damaged strand on either side of the lesion, resulting in a single-strand gap of 22-30 nucleotides. Next, the cell performs DNA gap filling synthesis and ligation. Involved in this process are: PCNA, RFC, DNA Pol ?, DNA Pol ? or DNA Pol ?, and DNA ligase I or XRCC1/Ligase III. Replicating cells tend to use DNA pol ? and DNA ligase I, while non-replicating cells tend to use DNA Pol ?, DNA Pol ?, and the XRCC1/Ligase III complex to perform the ligation step.

(740) NER can involve the following factors: XPA-G, POLH, XPF, ERCC1, XPA-G, and LIG1. Transcription-coupled NER (TC-NER) can involve the following factors: CSA, CSB, XPB, XPD, XPG, ERCC1, and TTDA. Additional factors that may promote the NER repair pathway include XPA-G, POLH, XPF, ERCC1, XPA-G, LIG1, CSA, CSB, XPA, XPB, XPC, XPD, XPF, XPG, TTDA, UVSSA, USP7, CETN2, RAD23B, UV-DDB, CAK subcomplex, RPA, and PCNA.

(e) Intrastrand Crosslink (ICL)

(741) A dedicated pathway called the ICL repair pathway repairs interstrand crosslinks. Interstrand crosslinks, or covalent crosslinks between bases in different DNA strand, can occur during replication or transcription. ICL repair involves the coordination of multiple repair processes, in particular, nucleolytic activity, translesion synthesis (TLS), and HDR. Nucleases are recruited to excise the ICL on either side of the crosslinked bases, while TLS and HDR are coordinated to repair the cut strands. ICL repair can involve the following factors: endonucleases, e.g., XPF and RAD51C, endonucleases such as RAD51, translesion polymerases, e.g., DNA polymerase zeta and Rev1), and the Fanconi anemia (FA) proteins, e.g., FancJ.

(f) Other Pathways

(742) Several other DNA repair pathways exist in mammals.

(743) Translesion synthesis (TLS) is a pathway for repairing a single stranded break left after a defective replication event and involves translesion polymerases, e.g., DNA pol? and Rev1.

(744) Error-free postreplication repair (PRR) is another pathway for repairing a single stranded break left after a defective replication event.

(7) Functional Analysis of Agents for Gene Editing

(756) Any of the Cas9 molecules, gRNA molecules, Cas9 molecule/gRNA molecule complexes, can be evaluated by art-known methods or as described herein. For example, exemplary methods for evaluating the endonuclease activity of Cas9 molecule are described, e.g., in Jinek et al., SCIENCE 2012, 337(6096):816-821.

(a) Binding and Cleavage Assay: Testing the Endonuclease Activity of Cas9 Molecule

(757) The ability of a Cas9 molecule/gRNA molecule complex to bind to and cleave a target nucleic acid can be evaluated in a plasmid cleavage assay. In this assay, synthetic or in vitro-transcribed gRNA molecule is pre-annealed prior to the reaction by heating to 95? C. and slowly cooling down to room temperature. Native or restriction digest-linearized plasmid DNA (300 ng (?8 nM)) is incubated for 60 min at 37? C. with purified Cas9 protein molecule (50-500 nM) and gRNA (50-500 nM, 1:1) in a Cas9 plasmid cleavage buffer (20 mM HEPES pH 7.5, 150 mM KCl, 0.5 mM DTT, 0.1 mM EDTA) with or without 10 mM MgCl.sub.2. The reactions are stopped with 5?DNA loading buffer (30% glycerol, 1.2% SDS, 250 mM EDTA), resolved by a 0.8 or 1% agarose gel electrophoresis and visualized by ethidium bromide staining. The resulting cleavage products indicate whether the Cas9 molecule cleaves both DNA strands, or only one of the two strands. For example, linear DNA products indicate the cleavage of both DNA strands. Nicked open circular products indicate that only one of the two strands is cleaved.

(758) Alternatively, the ability of a Cas9 molecule/gRNA molecule complex to bind to and cleave a target nucleic acid can be evaluated in an oligonucleotide DNA cleavage assay. In this assay, DNA oligonucleotides (10 pmol) are radiolabeled by incubating with 5 units T4 polynucleotide kinase and ?3-6 pmol (?20-40 mCi) [?-32P]-ATP in 1? T4 polynucleotide kinase reaction buffer at 37? C. for 30 min, in a 50 ?L reaction. After heat inactivation (65? C. for 20 min), reactions are purified through a column to remove unincorporated label. Duplex substrates (100 nM) are generated by annealing labeled oligonucleotides with equimolar amounts of unlabeled complementary oligonucleotide at 95? C. for 3 min, followed by slow cooling to room temperature. For cleavage assays, gRNA molecules are annealed by heating to 95? C. for 30 s, followed by slow cooling to room temperature. Cas9 (500 nM final concentration) is pre-incubated with the annealed gRNA molecules (500 nM) in cleavage assay buffer (20 mM HEPES pH 7.5, 100 mM KCl, 5 mM MgCl2, 1 mM DTT, 5% glycerol) in a total volume of 9 ?l. Reactions are initiated by the addition of 1 ?l target DNA (10 nM) and incubated for 1 h at 37? C. Reactions are quenched by the addition of 20 ?l of loading dye (5 mM EDTA, 0.025% SDS, 5% glycerol in formamide) and heated to 95? C. for 5 min. Cleavage products are resolved on 12% denaturing polyacrylamide gels containing 7 M urea and visualized by phosphorimaging. The resulting cleavage products indicate that whether the complementary strand, the non-complementary strand, or both, are cleaved.

(759) One or both of these assays can be used to evaluate the suitability of any of the gRNA molecule or Cas9 molecule provided.

(b) Binding Assay: Testing the Binding of Cas9 Molecule to Target DNA

(760) Exemplary methods for evaluating the binding of Cas9 molecule to target DNA are described, e.g., in Jinek et al., SCIENCE 2012; 337(6096):816-821.

(761) For example, in an electrophoretic mobility shift assay, target DNA duplexes are formed by mixing of each strand (10 nmol) in deionized water, heating to 95? C. for 3 min and slow cooling to room temperature. All DNAs are purified on 8% native gels containing 1?TBE. DNA bands are visualized by UV shadowing, excised, and eluted by soaking gel pieces in DEPC-treated H.sub.2O. Eluted DNA is ethanol precipitated and dissolved in DEPC-treated H.sub.2O. DNA samples are 5 end labeled with [?-32P]-ATP using T4 polynucleotide kinase for 30 min at 37? C. Polynucleotide kinase is heat denatured at 65? C. for 20 min, and unincorporated radiolabel is removed using a column. Binding assays are performed in buffer containing 20 mM HEPES pH 7.5, 100 mM KCl, 5 mM MgCl.sub.2, 1 mM DTT and 10% glycerol in a total volume of 10 ?l. Cas9 protein molecule is programmed with equimolar amounts of pre-annealed gRNA molecule and titrated from 100 pM to 1 ?M. Radiolabeled DNA is added to a final concentration of 20 pM. Samples are incubated for 1 h at 37? C. and resolved at 4? C. on an 8% native polyacrylamide gel containing 1?TBE and 5 mM MgCl.sub.2. Gels are dried and DNA visualized by phosphorimaging.

(c) Techniques for Measuring Thermostability of Cas9/gRNA Complexes

(762) The thermostability of Cas9-gRNA ribonucleoprotein (RNP) complexes can be detected by differential scanning fluorimetry (DSF) and other techniques. The thermostability of a protein can increase under favorable conditions such as the addition of a binding RNA molecule, e.g., a gRNA. Thus, information regarding the thermostability of a Cas9/gRNA complex is useful for determining whether the complex is stable.

(d) Differential Scanning Flourimetry (DSF)

(763) The thermostability of Cas9-gRNA ribonucleoprotein (RNP) complexes can be measured via DSF. RNP complexes, as described below, include a sequence of ribonucleotides, such as an RNA or a gRNA, and a protein, such as a Cas9 protein or variant thereof. This technique measures the thermostability of a protein, which can increase under favorable conditions such as the addition of a binding RNA molecule, e.g., a gRNA.

(764) The assay can be applied in a number of ways. Exemplary protocols include, but are not limited to, a protocol to determine the desired solution conditions for RNP formation (assay 1, see below), a protocol to test the desired stoichiometric ratio of gRNA:Cas9 protein (assay 2, see below), a protocol to screen for effective gRNA molecules for Cas9 molecules, e.g., wild-type or mutant Cas9 molecules (assay 3, see below), and a protocol to examine RNP formation in the presence of target DNA (assay 4). In some embodiments, the assay is performed using two different protocols, one to test the best stoichiometric ratio of gRNA:Cas9 protein and another to determine the best solution conditions for RNP formation.

(765) To determine the best solution to form RNP complexes, a 2 uM solution of Cas9 in water+10? SYPRO Orange? (Life Technologies cat #S-6650) and dispensed into a 384 well plate. An equimolar amount of gRNA diluted in solutions with varied pH and salt is then added. After incubating at room temperature for 10 and brief centrifugation to remove any bubbles, a Bio-Rad CFX384TM Real-Time System C1000 Touch? Thermal Cycler with the Bio-Rad CFX Manager software is used to run a gradient from 20? C. to 90? C. with a 1? increase in temperature every 10 seconds.

(766) The second assay consists of mixing various concentrations of gRNA with 2 uM Cas9 in optimal buffer from assay 1 above and incubating at RT for 10 in a 384 well plate. An equal volume of optimal buffer+10? SYPRO Orange? (Life Technologies cat #S-6650) is added and the plate sealed with Microseal? B adhesive (MSB-1001). Following brief centrifugation to remove any bubbles, a Bio-Rad CFX384TM Real-Time System C1000 Touch? Thermal Cycler with the Bio-Rad CFX Manager software is used to run a gradient from 20? C. to 90? C. with a 1? increase in temperature every 10 seconds.

(767) In the third assay, a Cas9 molecule (e.g., a Cas9 protein, e.g., a Cas9 variant protein) of interest is purified. A library of variant gRNA molecules is synthesized and resuspended to a concentration of 20 ?M. The Cas9 molecule is incubated with the gRNA molecule at a final concentration of 1 ?M each in a predetermined buffer in the presence of 5? SYPRO Orange? (Life Technologies cat #S-6650). After incubating at room temperature for 10 minutes and centrifugation at 2000 rpm for 2 minutes to remove any bubbles, a Bio-Rad CFX384? Real-Time System C1000 Touch? Thermal Cycler with the Bio-Rad CFX Manager software is used to run a gradient from 20? C. to 90? C. with an increase of 1? C. in temperature every 10 seconds.

(768) In the fourth assay, a DSF experiment is performed with the following samples: Cas9 protein alone, Cas9 protein with gRNA, Cas9 protein with gRNA and target DNA, and Cas9 protein with target DNA. The order of mixing components is: reaction solution, Cas9 protein, gRNA, DNA, and SYPRO Orange. The reaction solution contains 10 mM HEPES pH 7.5, 100 mM NaCl, in the absence or presence of MgCl2. Following centrifugation at 2000 rpm for 2 minutes to remove any bubbles, a Bio-Rad CFX384? Real-Time System C1000 Touch? Thermal Cycler with the Bio-Rad CFX Manager software is used to run a gradient from 20? C. to 90? C. with a 1? increase in temperature every 10 seconds.

b) Delivery of Agents for Gene Editing

(769) In some embodiments, a reduction, deletion, elimination, knockout or disruption of the endogenous genes encoding TCR, such as TRAC and TRBC1 or TRBC2, is carried out by delivering or introducing one or more agent(s) capable of introducing a cleavage, e.g., Cas9 and/or gRNA components, to a cell, using any of a number of known delivery method or vehicle for introduction or transfer to cells, for example, using lentiviral delivery vectors, or any of the known methods or vehicles for delivering Cas9 molecules and gRNAs. Exemplary methods are described in, e.g., Wang et al. (2012) J. Immunother. 35(9): 689-701; Cooper et al. (2003) Blood. 101:1637-1644; Verhoeyen et al. (2009) Methods Mol Biol. 506: 97-114; and Cavalieri et al. (2003) Blood. 102(2): 497-505, WO 2015/161276; US 2015/0056705, US 2016/0272999, US 2017/0211075; or US 2017/0016027. In some embodiments, nucleic acid sequences encoding one or more components of one or more agent(s) capable of introducing a cleavage, e.g., DNA break, is introduced into the cells, e.g., by any methods for introducing nucleic acids into a cell described herein or known. In some embodiments, a vector encoding components of one or more agent(s) capable of introducing a cleavage such as a CRISPR guide RNA and/or a Cas9 enzyme can be delivered into the cell.

(770) Cas9 molecules and gRNA molecules, e.g., a Cas9 molecule/gRNA molecule complex, can be used to manipulate a cell, e.g., to edit a target nucleic acid, in a wide variety of cells.

(771) In an embodiment, a cell is manipulated by editing (e.g., inducing a mutation in) one or more target genes, e.g., as described herein. In some embodiments, the expression of one or more target genes (e.g., TRAC, TRBC1 and/or TRBC2 gene) is modulated. In another embodiment, a cell is manipulated ex vivo by editing (e.g., inducing a mutation in) one or more target genes and/or modulating the expression of one or more target genes, e.g., TRAC, TRBC1 and/or TRBC2 gene, and administered to a subject.

In an embodiment, the target cell is an induced pluripotent stem (iPS) cell or a cell derived from an iPS cell, e.g., an iPS cell generated from a subject, manipulated to alter (e.g., induce a mutation in) or manipulate the expression of one or more target genes, e.g., TRAC, TRBC1 and/or TRBC2 gene, and differentiated into, e.g., a T cell, e.g., a CD8+ T cell (e.g., a CD8+na?ve T cell, central memory T cell, or effector memory T cell), a CD4+ T cell, a stem cell memory T cell, a lymphoid progenitor cell or a hematopoietic stem cell.

(773) In an embodiment, the target cell has been altered to contain specific T cell receptor (TCR) genes (e.g., a TRAC and TRBC gene).

(776) The components, e.g., a Cas9 molecule and gRNA molecule can be introduced into target cells in a variety of forms using a variety of delivery methods and formulations, see, e.g., Tables 19 and 20. When a Cas9 or gRNA component is encoded as DNA for delivery, the DNA may typically but not necessarily include a control region, e.g., comprising a promoter, to effect expression. Useful promoters for Cas9 molecule sequences include, e.g., CMV, EF-1a, EFS, MSCV, PGK, or CAG promoters. Useful promoters for gRNAs include, e.g., H1, EF-1a, tRNA or U6 promoters. Promoters with similar or dissimilar strengths can be selected to tune the expression of components. Sequences encoding a Cas9 molecule may comprise a nuclear localization signal (NLS), e.g., an SV40 NLS. In an embodiment a promoter for a Cas9 molecule or a gRNA molecule may be, independently, inducible, tissue specific, or cell specific. In some embodiments, an agent capable of inducing a genetic disruption is introduced RNP complexes. RNP complexes include a sequence of ribonucleotides, such as an RNA or a gRNA molecule, and a protein, such as a Cas9 protein or variant thereof. In some embodiments, the Cas9 protein is delivered as a ribonucleoprotein (RNP) complex that comprises a Cas9 protein provided herein and a gRNA molecule provided herein, e.g., a gRNA targeted for TRAC, TRBC1 and/or TRBC2. In some embodiments, the RNP that includes one or more gRNA molecules targeted for TRAC, TRBC1 and/or TRBC2, such as any as described, and a Cas9 enzyme or variant thereof, is directly introduced into the cell via physical delivery (e.g., electroporation, particle gun, Calcium Phosphate transfection, cell compression or squeezing), liposomes or nanoparticles. In particular embodiments, the RNP includes one or more gRNA molecules targeted for TRAC, TRBC1 and/or TRBC2 and a Cas9 enzyme or variant thereof is introduced via electroporation.

(a) DNA-Based Delivery of a Cas9 Molecule and/or a gRNA Molecule

(781) DNA encoding Cas9 molecules (e.g., eaCas9 molecules) and/or gRNA molecules, can be delivered into cells by art-known methods or as described herein. For example, Cas9-encoding and/or gRNA-encoding DNA can be delivered, e.g., by vectors (e.g., viral or non-viral vectors), non-vector based methods (e.g., using naked DNA or DNA complexes), or a combination thereof.

(782) In some embodiments, the Cas9- and/or gRNA-encoding DNA is delivered by a vector (e.g., viral vector/virus or plasmid).

(783) A vector may comprise a sequence that encodes a Cas9 molecule and/or a gRNA molecule. A vector may also comprise a sequence encoding a signal peptide (e.g., for nuclear localization, nucleolar localization, mitochondrial localization), fused, e.g., to a Cas9 molecule sequence. For example, a vector may comprise a nuclear localization sequence (e.g., from SV40) fused to the sequence encoding the Cas9 molecule.

(784) One or more regulatory/control elements, e.g., a promoter, an enhancer, an intron, a polyadenylation signal, a Kozak consensus sequence, internal ribosome entry sites (IRES), a 2A sequence, and splice acceptor or donor can be included in the vectors. In an embodiment, the promoter is recognized by RNA polymerase II (e.g., a CMV promoter). In another embodiment, the promoter is recognized by RNA polymerase III (e.g., a U6 promoter). In another embodiment, the promoter is a regulated promoter (e.g., inducible promoter). In another embodiment, the promoter is a constitutive promoter. In another embodiment, the promoter is a tissue specific promoter. In another embodiment, the promoter is a viral promoter. In another embodiment, the promoter is a non-viral promoter.

(785) In an embodiment, the vector or delivery vehicle is a viral vector (e.g., for generation of recombinant viruses). In an embodiment, the virus is a DNA virus (e.g., dsDNA or ssDNA virus). In an embodiment, the virus is an RNA virus (e.g., an ssRNA virus). Exemplary viral vectors/viruses include, e.g., retroviruses, lentiviruses, adenovirus, adeno-associated virus (AAV), vaccinia viruses, poxviruses, and herpes simplex viruses.

(786) In an embodiment, the virus infects dividing cells. In another embodiment, the virus infects non-dividing cells. In another embodiment, the virus infects both dividing and non-dividing cells. In another embodiment, the virus can integrate into the host genome. In another embodiment, the virus is engineered to have reduced immunity, e.g., in human. In another embodiment, the virus is replication-competent. In another embodiment, the virus is replication-defective, e.g., having one or more coding regions for the genes necessary for additional rounds of virion replication and/or packaging replaced with other genes or deleted. In another embodiment, the virus causes transient expression of the Cas9 molecule and/or the gRNA molecule. In another embodiment, the virus causes long-lasting, e.g., at least 1 week, 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 1 year, 2 years, or permanent expression, of the Cas9 molecule and/or the gRNA molecule. The packaging capacity of the viruses may vary, e.g., from at least about 4 kb to at least about 30 kb, e.g., at least about 5 kb, 10 kb, 15 kb, 20 kb, 25 kb, 30 kb, 35 kb, 40 kb, 45 kb, or 50 kb.

(787) In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a recombinant retrovirus. In another embodiment, the retrovirus (e.g., Moloney murine leukemia virus) comprises a reverse transcriptase, e.g., that allows integration into the host genome. In an embodiment, the retrovirus is replication-competent. In another embodiment, the retrovirus is replication-defective, e.g., having one of more coding regions for the genes necessary for additional rounds of virion replication and packaging replaced with other genes, or deleted.

(788) In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a recombinant lentivirus. For example, the lentivirus is replication-defective, e.g., does not comprise one or more genes required for viral replication.

(789) In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a recombinant adenovirus. In another embodiment, the adenovirus is engineered to have reduced immunity in humans.

(790) In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a recombinant AAV. In an embodiment, the AAV can incorporate its genome into that of a host cell, e.g., a target cell as described herein. In another embodiment, the AAV is a self-complementary adeno-associated virus (scAAV), e.g., a scAAV that packages both strands which anneal together to form double stranded DNA. AAV serotypes that may be used in the disclosed methods, include AAV1, AAV2, modified AAV2 (e.g., modifications at Y444F, Y500F, Y730F and/or S662V), AAV3, modified AAV3 (e.g., modifications at Y705F, Y731F and/or T492V), AAV4, AAV5, AAV6, modified AAV6 (e.g., modifications at S663V and/or T492V), AAV8, AAV 8.2, AAV9, AAV rh 10, and pseudotyped AAV, such as AAV2/8, AAV2/5 and AAV2/6 can also be used in the disclosed methods.

(791) In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a hybrid virus, e.g., a hybrid of one or more of the viruses described herein.

(792) A packaging cell is used to form a virus particle that is capable of infecting a target cell. Such a cell includes a 293 cell, which can package adenovirus, and a ?2 cell or a PA317 cell, which can package retrovirus. A viral vector used in gene therapy is usually generated by a producer cell line that packages a nucleic acid vector into a viral particle. The vector typically contains the minimal viral sequences required for packaging and subsequent integration into a host or target cell (if applicable), with other viral sequences being replaced by an expression cassette encoding the protein to be expressed, eg. Cas9. For example, an AAV vector used in gene therapy typically only possesses inverted terminal repeat (ITR) sequences from the AAV genome which are required for packaging and gene expression in the host or target cell. The missing viral functions are supplied in trans by the packaging cell line. Henceforth, the viral DNA is packaged in a cell line, which contains a helper plasmid encoding the other AAV genes, namely rep and cap, but lacking ITR sequences. The cell line is also infected with adenovirus as a helper. The helper virus promotes replication of the AAV vector and expression of AAV genes from the helper plasmid. The helper plasmid is not packaged in significant amounts due to a lack of ITR sequences. Contamination with adenovirus can be reduced by, e.g., heat treatment to which adenovirus is more sensitive than AAV.

(793) In an embodiment, the viral vector has the ability of cell type recognition. For example, the viral vector can be pseudotyped with a different/alternative viral envelope glycoprotein; engineered with a cell type-specific receptor (e.g., genetic modification of the viral envelope glycoproteins to incorporate targeting ligands such as a peptide ligand, a single chain antibody, a growth factor); and/or engineered to have a molecular bridge with dual specificities with one end recognizing a viral glycoprotein and the other end recognizing a moiety of the target cell surface (e.g., ligand-receptor, monoclonal antibody, avidin-biotin and chemical conjugation).

(794) In an embodiment, the viral vector achieves cell type specific expression. For example, a tissue-specific promoter can be constructed to restrict expression of the transgene (Cas 9 and gRNA) in only a specific target cell. The specificity of the vector can also be mediated by microRNA-dependent control of transgene expression. In an embodiment, the viral vector has increased efficiency of fusion of the viral vector and a target cell membrane. For example, a fusion protein such as fusion-competent hemagglutinin (HA) can be incorporated to increase viral uptake into cells. In an embodiment, the viral vector has the ability of nuclear localization. For example, a virus that requires the breakdown of the nuclear membrane (during cell division) and therefore will not infect a non-diving cell can be altered to incorporate a nuclear localization peptide in the matrix protein of the virus thereby enabling the transduction of non-proliferating cells.

(795) In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a non-vector based method (e.g., using naked DNA or DNA complexes). For example, the DNA can be delivered, e.g., by organically modified silica or silicate (Ormosil), electroporation, transient cell compression or squeezing (e.g., as described in Lee, et al [2012] Nano Lett 12: 6322-27), gene gun, sonoporation, magnetofection, lipid-mediated transfection, dendrimers, inorganic nanoparticles, calcium phosphates, or a combination thereof.

(796) In an embodiment, delivery via electroporation comprises mixing the cells with the Cas9- and/or gRNA-encoding DNA in a cartridge, chamber or cuvette and applying one or more electrical impulses of defined duration and amplitude. In an embodiment, delivery via electroporation is performed using a system in which cells are mixed with the Cas9- and/or gRNA-encoding DNA in a vessel connected to a device (e.g., a pump) which feeds the mixture into a cartridge, chamber or cuvette wherein one or more electrical impulses of defined duration and amplitude are applied, after which the cells are delivered to a second vessel.

(797) In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a combination of a vector and a non-vector based method. For example, a virosome comprises a liposome combined with an inactivated virus (e.g., HIV or influenza virus), which can result in more efficient gene transfer than either a viral or a liposomal method alone.

(798) In an embodiment, the delivery vehicle is a non-viral vector. In an embodiment, the non-viral vector is an inorganic nanoparticle. Exemplary inorganic nanoparticles include, e.g., magnetic nanoparticles (e.g., Fe.sub.3MnO.sub.2) and silica. The outer surface of the nanoparticle can be conjugated with a positively charged polymer (e.g., polyethylenimine, polylysine, polyserine) which allows for attachment (e.g., conjugation or entrapment) of payload. In an embodiment, the non-viral vector is an organic nanoparticle. Exemplary organic nanoparticles include, e.g., SNALP liposomes that contain cationic lipids together with neutral helper lipids which are coated with polyethylene glycol (PEG), and protamine-nucleic acid complexes coated with lipid.

(799) Exemplary lipids for gene transfer are shown below in Table 21.

(803) In an embodiment, the vehicle has targeting modifications to increase target cell update of nanoparticles and liposomes, e.g., cell specific antigens, monoclonal antibodies, single chain antibodies, aptamers, polymers, sugars, and cell penetrating peptides. In an embodiment, the vehicle uses fusogenic and endosome-destabilizing peptides/polymers. In an embodiment, the vehicle undergoes acid-triggered conformational changes (e.g., to accelerate endosomal escape of the cargo). In an embodiment, a stimulus-cleavable polymer is used, e.g., for release in a cellular compartment. For example, disulfide-based cationic polymers that are cleaved in the reducing cellular environment can be used.

(804) In an embodiment, the delivery vehicle is a biological non-viral delivery vehicle. In an embodiment, the vehicle is an attenuated bacterium (e.g., naturally or artificially engineered to be invasive but attenuated to prevent pathogenesis and expressing the transgene (e.g., Listeria monocytogenes, certain Salmonella strains, Bifidobacterium longum, and modified Escherichia coli), bacteria having nutritional and tissue-specific tropism to target specific cells, bacteria having modified surface proteins to alter target cell specificity). In an embodiment, the vehicle is a genetically modified bacteriophage (e.g., engineered phages having large packaging capacity, less immunogenicity, containing mammalian plasmid maintenance sequences and having incorporated targeting ligands). In an embodiment, the vehicle is a mammalian virus-like particle. For example, modified viral particles can be generated (e.g., by purification of the empty particles followed by ex vivo assembly of the virus with the desired cargo). The vehicle can also be engineered to incorporate targeting ligands to alter target tissue specificity. In an embodiment, the vehicle is a biological liposome. For example, the biological liposome is a phospholipid-based particle derived from human cells (e.g., erythrocyte ghosts, which are red blood cells broken down into spherical structures derived from the subject (e.g., tissue targeting can be achieved by attachment of various tissue or cell-specific ligands), or secretory exosomessubject-derived membrane-bound nanovescicles (30-100 nm) of endocytic origin (e.g., can be produced from various cell types and can therefore be taken up by cells without the need for targeting ligands).

(805) In an embodiment, one or more nucleic acid molecules (e.g., DNA molecules) other than the components of a Cas system, e.g., the Cas9 molecule component and/or the gRNA molecule component described herein, are delivered. In an embodiment, the nucleic acid molecule is delivered at the same time as one or more of the components of the Cas system. In an embodiment, the nucleic acid molecule is delivered before or after (e.g., less than about 30 minutes, 1 hour, 2 hours, 3 hours, 6 hours, 9 hours, 12 hours, 1 day, 2 days, 3 days, 1 week, 2 weeks, or 4 weeks) one or more of the components of the Cas system are delivered. In an embodiment, the nucleic acid molecule is delivered by a different means from one or more of the components of the Cas system, e.g., the Cas9 molecule component and/or the gRNA molecule component. The nucleic acid molecule can be delivered by any of the delivery methods described herein. For example, the nucleic acid molecule can be delivered by a viral vector, e.g., a retrovirus or a lentivirus, and the Cas9 molecule component and/or the gRNA molecule component can be delivered by electroporation. In an embodiment, the nucleic acid molecule encodes a TRAC gene, a TRBC gene or a CAR gene.

(b) Delivery of RNA Encoding a Cas9 Molecule

(806) RNA encoding Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) and/or gRNA molecules, can be delivered into cells, e.g., target cells described herein, by art-known methods or as described herein. For example, Cas9-encoding and/or gRNA-encoding RNA can be delivered, e.g., by microinjection, electroporation, transient cell compression or squeezing (eg, as described in Lee, et al [2012] Nano Lett 12: 6322-27), lipid-mediated transfection, peptide-mediated delivery, or a combination thereof.

(807) In an embodiment, delivery via electroporation comprises mixing the cells with the RNA encoding Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) and/or gRNA molecules in a cartridge, chamber or cuvette and applying one or more electrical impulses of defined duration and amplitude. In an embodiment, delivery via electroporation is performed using a system in which cells are mixed with the RNA encoding Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) and/or gRNA molecules in a vessel connected to a device (eg, a pump) which feeds the mixture into a cartridge, chamber or cuvette wherein one or more electrical impulses of defined duration and amplitude are applied, after which the cells are delivered to a second vessel.

(c) Delivery of Cas9 Protein and Ribonucleoprotein (RNP)

(808) In some embodiments, the one or more agent(s) capable of introducing a cleavage, e.g., a Cas9/gRNA system, is introduced into the cell as a ribonucleoprotein (RNP) complex. RNP complexes include a sequence of ribonucleotides, such as an RNA or a gRNA molecule, and a protein, such as a Cas9 protein or variant thereof. For example, the Cas9 protein is delivered as RNP complex that comprises a Cas9 protein and a gRNA molecule targeting the target sequence, e.g., using electroporation or other physical delivery method. In some embodiments, the RNP is delivered into the cell via electroporation or other physical means, e.g., particle gun, calcium phosphate transfection, cell compression or squeezing. In some embodiments, the RNP can cross the plasma membrane of a cell without the need for additional delivery agents (e.g., small molecule agents, lipids, etc.).

(809) In some embodiments, delivery of the one or more agent(s) capable of inducing genetic disruption, e.g., CRISPR/Cas9, as an RNP offers an advantage that the targeted disruption occurs transiently, e.g., in cells to which the RNP is introduced, without propagation of the agent to cell progenies. For example, delivery by RNP minimizes the agent from being inherited to its progenies, thereby reducing the chance of off-target genetic disruption in the progenies.

(810) In some embodiments, more than one agent(s) or components thereof are delivered to the cell. For example, in some embodiments, agent(s) capable of inducing a genetic disruption of two or more locations in the genome, e.g., the TRAC, TRBC1 and/or TRBC2 loci, are delivered to the cell. In some embodiments, agent(s) and components thereof are delivered using one method. For example, in some embodiments, agent(s) for inducing a genetic disruption of TRAC, TRBC1 and/or TRBC2 loci are delivered as polynucleotides encoding the components for genetic disruption. In some embodiments, one polynucleotide can encode agents that target the TRAC, TRBC1 and/or TRBC2 loci. In some embodiments, two or more different polynucleotides can encode the agents that target TRAC, TRBC1 and/or TRBC2 loci. In some embodiments, the agents capable of inducing a genetic disruption can be delivered as ribonucleoprotein (RNP) complexes, and two or more different RNP complexes can be delivered together as a mixture, or separately.

(811) Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) can be delivered into cells by art-known methods or as described herein. For example, Cas9 protein molecules can be delivered, e.g., by microinjection, electroporation, transient cell compression or squeezing (eg, as described in Lee, et al [2012] Nano Lett 12: 6322-27), lipid-mediated transfection, peptide-mediated delivery, or a combination thereof. Delivery can be accompanied by DNA encoding a gRNA or by a gRNA. In some embodiments, the Cas9 protein is delivered as a ribonucleoprotein (RNP) complex that comprises a Cas9 protein provided herein and a gRNA molecule provided herein, e.g., a gRNA targeted for TRAC, TRBC1 and/or TRBC2. In some embodiments, a RNP complex includes a sequence of ribonucleotides, such as an RNA or a gRNA molecule, and a protein, such as a Cas9 protein or variant thereof. In some embodiments, the RNP that includes one or more gRNA molecules targeted for TRAC, TRBC1 and/or TRBC2 such as any as described and a Cas9 enzyme or variant thereof, is directly introduced into the cell via physical delivery (e.g., electroporation, particle gun, Calcium Phosphate transfection, cell compression or squeezing), liposomes or nanoparticles. In particular embodiments, the RNP includes one or more gRNA molecules targeted for TRAC, TRBC1 and/or TRBC2, such as any as described, and a Cas9 enzyme or variant thereof is introduced via electroporation.

(812) In an embodiment, delivery via electroporation comprises mixing the cells with the Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) with or without gRNA molecules in a cartridge, chamber or cuvette and applying one or more electrical impulses of defined duration and amplitude. In an embodiment, delivery via electroporation is performed using a system in which cells are mixed with the Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) with or without gRNA molecules in a vessel connected to a device (e.g., a pump) which feeds the mixture into a cartridge, chamber or cuvette wherein one or more electrical impulses of defined duration and amplitude are applied, after which the cells are delivered to a second vessel.

(813) B. Targeted Integration Via Homology Directed Repair (HDR)

(814) In some of the embodiments provided herein, homology-directed repair (HDR) can be utilized for targeted integration of a specific portion of the template polynucleotide containing a transgene, e.g., nucleic acid sequence encoding any of the provided recombinant receptors, e.g., recombinant T cell receptor (TCR), at a particular location in the genome, e.g., the TRAC, TRBC1 and/or TRBC2 locus. In some embodiments, a template polynucleotide comprising a nucleic acid sequence, e.g., a transgene, encoding a recombinant T cell receptor (TCR) or antigen-binding fragment or chain thereof is introduced into a cell, e.g., an immune cell, having a genetic disruption of a target site within a T cell receptor alpha constant (TRAC) gene and/or a T cell receptor beta constant (TRBC) gene. In some embodiments, the nucleic acid sequence or transgene encoding the recombinant TCR or antigen-binding fragment or chain thereof is targeted for integration at or near the target site via homology directed repair (HDR). In particular embodiments, the integration at or near the target site is within a portion of coding sequence of a TRAC and/or TRBC gene, such as, for example, a portion of the coding sequence downstream of, or 3 of the target site.

(815) In some embodiments, the target site is in a T cell receptor alpha constant (TRAC) gene. In some embodiments, the target site(s) is in a T cell receptor beta constant 1 (TRBC1) or T cell receptor beta constant 2 (TRBC2) gene. In some embodiments, one or more target sites are in a TRAC gene and one or both of a TRBC1 and a TRBC2 gene. In some embodiments, a template polynucleotide containing a nucleic acid sequence and/or a transgene encoding a recombinant receptor, such as any of the provided TCRs or a portion thereof, is introduced into an immune cell having a genetic disruption of one or more target site(s) within a TRAC, a TRBC1, and/or a TRBC2 gene is targeted at or near one of the at least one target site(s) via HDR.

(816) In some embodiments, the targeted genetic disruption and targeted integration of the recombinant receptor-encoding nucleic acids by HDR occurs at one or more target site(s) (also known as target position, target DNA sequence or target location) the endogenous genes that encode one or more domains, regions and/or chains of the endogenous T cell receptor (TCR). In certain embodiments, the embodiments provided herein involve one or more targeted genetic disruption(s), e.g., DNA break, at one or more of the endogenous TCR gene loci (such as the endogenous genes encoding the TCR? and/or the TCR? constant domains) by gene editing techniques, combined with targeted knock-in of nucleic acids encoding the recombinant receptor (such as a recombinant TCR or a CAR) by homology-directed repair (HDR). In some embodiments, the DNA break occurs as a result of a step in gene editing, for example, DNA breaks generated by targeted nucleases used to introduce a targeted genetic disruption, such as any described herein. Exemplary methods for gene editing endogenous TCR loci are known, and include but are not limited to those described herein or elsewhere, e.g., U.S. Publication Nos.

(817) Alteration of nucleic acid sequences at the target site can occur by HDR with an exogenously provided template polynucleotide (also referred to as donor polynucleotide or template sequence). For example, the template polynucleotide provides for alteration of the target sequence, such as insertion of the transgene contained within the template polynucleotide. In some embodiments, a plasmid or a vector can be used as a template for homologous recombination. In some embodiments, a linear DNA fragment can be used as a template for homologous recombination. In some embodiments, a single stranded template polynucleotide can be used as a template for alteration of the target sequence by alternate methods of homology directed repair (e.g., single strand annealing) between the target sequence and the template polynucleotide. Template polynucleotide-effected alteration of a target sequence depends on cleavage by a nuclease, e.g., a targeted nuclease such as CRISPR/Cas9. Cleavage by the nuclease can comprise a double strand break or two single strand breaks.

(818) In some embodiments, methods for HDR involve introducing into an immune cell, e.g. a T cell, one or more agent wherein each of the one or more agent is independently capable of inducing a genetic disruption of a T cell receptor alpha constant (TRAC) gene and/or a T cell receptor beta constant (TRBC) gene. In some embodiments, the one or more agents can include a zinc finger nuclease (ZFN), a TAL-effector nuclease (TALEN), or and a CRISPR-Cas9 combination that specifically binds to, recognizes, or hybridizes to the target site in the TRAC or TRBC locus, such as using methods described above in Section V.A. In some embodiments, the one or more agents are introduced using a CRISPR-Cas9 combination, in which each of the one or more agent comprises a guide RNA (gRNA) having a targeting domain that is complementary to the at least one target site. Any gRNA targeting domain sequences that targets the TRAC or TRBC locus can be used for carrying out genetic disruption, including any described above. In some embodiments, the TRAC locus for targeting the TRAC locus is GAGAAUCAAAAUCGGUGAAU (SEQ ID NO:1048). In some embodiments, the gRNA targeting domain sequence for targeting the TRBC locus is GGCCUCGGCGCUGACGAUCU (SEQ ID NO:1053).

(819) In some embodiments, the HDR involves introducing into an immune cell, e.g. a T cell, one or more gRNA targeting sequences capable of inducing a genetic disruption of a T cell receptor alpha constant (TRAC) gene.

(820) In some embodiments, the genetic disruption is carried out by introducing into the cell the gRNA targeting domain sequence together with a Cas9, such as using methods described above. The Cas9 can be introduced as a nucleic acid or as an encoded protein. In some embodiments, the genetic disruption is carried out by introducing into the cell, such as via electroporation, a ribonucleoprotein (RNP) complex comprising the gRNA and a Cas9 protein, such as using methods described above.

(821) In some embodiments, HDR methods further include introducing into the cell a polynucleotide, such as a template polynucleotide, that contains (a) a nucleic acid sequence encoding any of the provided TCR or antigen-binding portions thereof and (b) one or more homology arms linked to the nucleic acid sequence, wherein the one or more homology arms comprise a sequence homologous to one or more region(s) of an open reading frame of a T cell receptor alpha constant (TRAC) locus. In some embodiments, the one or more homology arms facilitate transfer of genetic information from the template polynucleotide to the target locus, e.g. a target site of the TRAC locus.

(822) In some embodiments, recombination refers to a process of exchange of genetic information between two polynucleotides. In some embodiments, homologous recombination (HR) refers to the specialized form of such exchange that takes place, for example, during repair of double-strand breaks in cells via homology-directed repair mechanisms. This process requires nucleotide sequence homology, uses a template polynucleotide to template repair of a target DNA (i.e., the one that experienced the double-strand break, e.g., target site in the endogenous gene), and is variously known as non-crossover gene conversion or short tract gene conversion, because it leads to the transfer of genetic information from the template polynucleotide to the target. In some embodiments, such transfer can involve mismatch correction of heteroduplex DNA that forms between the broken target, e.g. due to genetic disruption, and the template polynucleotide, and/or synthesis-dependent strand annealing, in which the template polynucleotide is used to resynthesize genetic information that will become part of the target, and/or related processes. Such specialized HR often results in an alteration of the sequence of the target molecule such that part or all of the sequence of the template polynucleotide is incorporated into the target polynucleotide.

(823) In some embodiments, a template polynucleotide, e.g., polynucleotide containing transgene, is integrated into the genome of a cell via homology-independent mechanisms. The methods comprise creating a double-stranded break (DSB) in the genome of a cell and cleaving the template polynucleotide molecule using a nuclease, such that the template polynucleotide is integrated at the site of the DSB. In some embodiments, the template polynucleotide is integrated via non-homology dependent methods (e.g., NHEJ). Upon in vivo cleavage the template polynucleotides can be integrated in a targeted manner into the genome of a cell at the location of a DSB. The template polynucleotide can include one or more of the same target sites for one or more of the nucleases used to create the DSB. Thus, the template polynucleotide may be cleaved by one or more of the same nucleases used to cleave the endogenous gene into which integration is desired. In some embodiments, the template polynucleotide includes different nuclease target sites from the nucleases used to induce the DSB. As described herein, the genetic disruption of the target site or target position can be created by any mechanisms, such as ZFNs, TALENs, CRISPR/Cas9 system, or TtAgo nucleases.

(824) In some of the embodiments provided herein, homology-directed repair (HDR) can be utilized for targeted integration of a specific portion of the template polynucleotide containing a transgene, e.g., nucleic acid sequence encoding any of the provided recombinant receptors, e.g., recombinant TCRs, at a particular location in the genome, e.g., the TRAC, TRBC1 and/or TRBC2 locus. In some embodiments, the presence of a genetic disruption (e.g., a DNA break) and a polynucleotide, e.g., a template polynucleotide containing one or more homology arms (e.g., nucleic acid sequences homologous to sequences surrounding the genetic disruption) are used to induce or direct HDR, with homologous sequences acting as a template for DNA repair.

(825) In some embodiments, a template polynucleotide having homology with sequences at or near one or more target site(s) in the endogenous DNA can be used to alter the structure of a target DNA, e.g., targeted insertion of the transgene. In some embodiments, the template polynucleotide contains homology sequences (e.g., homology arms) flanking the transgene, e.g., nucleic acid sequences encoding a recombinant receptor, for targeted insertion. In some embodiments, the homology sequences target the transgene at one or more of the TRAC, TRBC1 and/or TRBC2 loci. In some embodiments, the template polynucleotide includes additional sequences (coding or non-coding sequences) between the homology arms, such as a regulatory sequences, such as promoters and/or enhancers, splice donor and/or acceptor sites, internal ribosome entry site (IRES), sequences encoding ribosome skipping elements (e.g., 2A peptides), markers and/or SA sites, and/or one or more additional transgenes.

(826) In certain embodiments, the template polynucleotide includes or contains a transgene, a portion of a transgene, and/or a nucleic acid encodes recombinant receptor such as a recombinant TCR or chain thereof that contains one or more variable domains and one or more constant domains. In certain embodiments, the recombinant TCR or chain thereof contains one or more constant domains that shares complete, e.g., at or about 100% identity, to all or a portion and/or fragment of an endogenous TCR constant domain. In some embodiments, the transgene encodes all or a portion of a constant domain, e.g., a portion or fragment of the constant domain that is completely or partially identical to an endogenous TCR constant domain. In some embodiments, the transgene contains nucleotides of a sequence having at or at least 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, 99.5%, or 99.9% sequence identity to all or a portion of the nucleic acid sequence set forth in SEQ ID NOS: 348, 349 or 1047.

(827) In some of embodiments, the transgene contains a sequence encoding a TCR? and/or TCR? chain or a portion thereof that has been codon-optimized. In some embodiments, the transgene encodes a portion of a TCR? and/or TCR? chain with less than 100% amino acid sequence identity to a corresponding portion of a native or endogenous TCR? and/or TCR? chain. In some embodiments, the encoded TCR? and/or TCR? chain contains an amino acid sequence with, with about, or with at least 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99%, or greater than 99% identity but less than 100% identity to a corresponding native or endogenous TCR? and/or TCR? chain. In particular embodiments, the transgene encodes a TCR? and/or TCR? constant domain or portion thereof with less than 100% amino acid sequence identity to a corresponding native or endogenous TCR? and/or TCR? constant domain. In some embodiments, the TCR? and/or TCR? constant domain contains an amino acid sequence with, with about, or with at least 70%, 75%, 80%, 85%, 90%, 95%, 98%, 99%, or greater than 99% identity but less than 100% identity to a corresponding native or endogenous TCR? and/or TCR? chain. In particular embodiments, the transgene encodes a TCR? and/or TCR? chain and/or a TCR? and/or TCR? chain constant domains containing one or more modifications to introduce one or more disulfide bonds. In some embodiments, the transgene encodes a TCR? and/or TCR? chain and/or a TCR? and/or TCR? with one or more modifications to remove or prevent a native disulfide bond, e.g., between the TCR? encoded by the transgene and the endogenous TCR? chain, or between the TCR ? encoded by the transgene and the endogenous TCR ? chain. In some embodiments, one or more native cysteines that form and/or are capable of forming a native inter-chain disulfide bond are substituted to another residue, e.g., serine or alanine. In some embodiments, the TCR? and/or TCR? chain and/or a TCR? and/or TCR? chain constant domains are modified to replace one or more non-cysteine residues to a cysteine. In some embodiments, the one or more non-native cysteine residues are capable of forming non-native disulfide bonds, e.g., between the recombinant TCR? and TCR? chain encoded by the transgene. In some embodiments, the cysteine is introduced at one or more of residue Thr48, Thr45, Tyr10, Thr45, and Ser15 with reference to numbering of a TCR? constant domain set forth in SEQ ID NO: 1352. In certain embodiments, cysteines can be introduced at residue Ser57, Ser77, Ser17, Asp59, of Glu15 of the TCR ? chain with reference to numbering of TCR? chain set forth in SEQ ID NO: 1353. Exemplary non-native disulfide bonds of a TCR are described in published International PCT No. WO2006/000830, WO 2006/037960 and Kuball et al. (2007) Blood, 109:2331-2338.

(828) In certain embodiments, the transgene contains one or more modifications(s) to introduce one or more cysteine residues that are capable of forming one or more non-native disulfide bridges between the TCR? chain and TCR? chain. In some embodiments, the transgene encodes a TCR? chain or a portion or fragment thereof containing a TCR? constant domain containing a cysteine at a position corresponding to position 48 with numbering as set forth in SEQ ID NO: 1355. In some embodiments, the TCR? constant domain has an amino acid sequence set forth in any of SEQ ID NOS: 1352 or 1355, or a sequence of amino acids that has, has about, or has at least 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99% sequence identity thereto containing one or more cysteine residues capable of forming a non-native disulfide bond with a TCR? chain. In some embodiments, the transgene encodes a TCR? chain or a portion thereof containing a TCR? constant domain containing a cysteine at a position corresponding to position 57 with numbering as set forth in SEQ ID NO: 1353. In some embodiments, the TCR? constant domain has an amino acid sequence set forth in any of SEQ ID NOS: 1353, 1354, or 1356, or a sequence of amino acids that has, has about, or has at least 70%, 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99% sequence identity thereto containing one or more cysteine residues capable of forming a non-native disulfide bond with a TCR? chain.

(829) The template polynucleotide can be DNA, single-stranded and/or double-stranded and can be introduced into a cell in linear or circular form. See also, U.S. Patent Publication Nos. 20100047805 and 20110207221. The template polynucleotide can also be introduced in DNA form, which may be introduced into the cell in circular or linear form. If introduced in linear form, the ends of the template polynucleotide can be protected (e.g., from exonucleolytic degradation) by known methods. For example, one or more dideoxynucleotide residues are added to the 3 terminus of a linear molecule and/or self-complementary oligonucleotides are ligated to one or both ends. See, for example, Chang et al. (1987) Proc. Natl. Acad. Sci. USA 84:4959-4963; Nehls et al. (1996) Science 272:886-889. Additional methods for protecting exogenous polynucleotides from degradation include, but are not limited to, addition of terminal amino group(s) and the use of modified internucleotide linkages such as, for example, phosphorothioates, phosphoramidates, and O-methyl ribose or deoxyribose residues. If introduced in double-stranded form, the template polynucleotide may include one or more nuclease target site(s), for example, nuclease target sites flanking the transgene to be integrated into the cell's genome. See, e.g., U.S. Patent Publication No. 20130326645.

(830) In some embodiments, the template polynucleotide contains the transgene, e.g., recombinant receptor-encoding nucleic acid sequences, flanked by homology sequences (also called homology arms) on the 5 and 3 ends, to allow the DNA repair machinery, e.g., homologous recombination machinery, to use the template polynucleotide as a template for repair, effectively inserting the transgene into the target site of integration in the genome. The homology arm should extend at least as far as the region in which end resection may occur, e.g., in order to allow the resected single stranded overhang to find a complementary region within the template polynucleotide. In some embodiments, a homology arm does not extend into repeated elements, e.g., ALU repeats or LINE repeats. Based on homology between the endogenous gene sequence surrounding the genetic disruption and the 5 and/or 3 homology arms included in the polynucleotide, e.g., template polynucleotide, cellular DNA repair machinery can use the template polynucleotide to repair the DNA break and resynthesize genetic information at the site of the genetic disruption, thereby effectively inserting or integrating the transgene sequences in the template polynucleotide at or near the site of the genetic disruption.

(831) In some embodiments, a template polynucleotide comprises the following components: [5 homology arm]-[transgene]-[3 homology arm]. The homology arms provide for recombination into the chromosome, thus insertion of the transgene into the DNA at or near the cleavage site, e.g., target site(s). In some embodiments, the homology arms flank the most distal target site(s).

(832) In some aspects, the transgene (e.g., exogenous nucleic acid sequences) within the template polynucleotide can be used to guide the location of target sites and/or homology arms. In some aspects, the target site of genetic disruption can be used as a guide to design template polynucleotides and/or homology arms used for HDR. In some embodiments, the genetic disruption can be targeted near a desired site of targeted integration of transgene sequences (e.g., encoding a recombinant TCR or a portion thereof). In some aspects, the target site is within an exon of the open reading frame of the TRAC, TRBC1 and/or TRBC2 locus. In some aspects, the target site is within an intron of the open reading frame of the TRAC, TRBC1 and/or TRBC2 locus.

(833) Exemplary homology arm lengths include at least or at least about or is or is about 50, 100, 200, 250, 300, 400, 500, 600, 700, 750, 800, 900, 1000, 2000, 3000, 4000, or 5000 nucleotides. Exemplary homology arm lengths include less than or less than about or is or is about 50, 100, 200, 250, 300, 400, 500, 600, 700, 750, 800, 900, 1000, 2000, 3000, 4000, or 5000 nucleotides. In some embodiments, the homology arm length is 50-100, 100-250, 250-500, 500-750, 750-1000, 1000-2000, 2000-3000, 3000-4000, or 4000-5000 nucleotides. In certain embodiments, the template polynucleotide comprises at least or less than or about 200, 300, 400, 500, 600, 700, 800, 900 or 1000 base pairs of homology 5 of the target site, 3 of the target site, or both 5 and 3 of the target site, e.g., within the TRAC, TRBC1, and/or TRBC2 gene, locus, or open reading frame. In particular embodiments, the template polynucleotide contains nucleotide sequences, e.g., homology arms, having homology 5 of the target site, 3 of the target site, or both 5 and 3 of the target site, e.g., within the TRAC gene, locus, or open reading frame. In some embodiments, exemplary 5 and 3 homology arms for targeted integration at the TRAC locus are set forth in SEQ ID NOS: 1343 and 1344, respectively.

(834) In some embodiments, the template polynucleotide can be linear single stranded DNA. In some embodiments, the template polynucleotide is (i) linear single stranded DNA that can anneal to the nicked strand of the target DNA, (ii) linear single stranded DNA that can anneal to the intact strand of the target DNA, (iii) linear single stranded DNA that can anneal to the transcribed strand of the target DNA, (iv) linear single stranded DNA that can anneal to the non-transcribed strand of the target DNA, or more than one of the preceding.

(835) In some embodiments, the template polynucleotide contains homology arms for targeting the endogenous TRAC locus (exemplary nucleotide sequence of the human TRAC gene locus set forth in SEQ ID NO:348; NCBI Reference Sequence: NG_001332.3, TRAC or described in Table 13 herein). In some embodiments, the genetic disruption of the TRAC locus is introduced at early coding region the gene, including sequence immediately following a transcription start site, within a first exon of the coding sequence, or within 500 bp of the transcription start site (e.g., less than 500, 450, 400, 350, 300, 250, 200, 150, 100 or 50 bp), or within 500 bp of the start codon (e.g., less than 500, 450, 400, 350, 300, 250, 200, 150, 100 or 50 bp). In some embodiments, the genetic disruption is introduced using any of the targeted nucleases and/or gRNAs. In some embodiments, the template polynucleotide comprises about 500 to 1000, e.g., 600 to 900 or 700 to 800, base pairs of homology on either side of the genetic disruption introduced by the targeted nucleases and/or gRNAs. In some embodiments, the template polynucleotide comprises about 500, 600, 700, 800, 900 or 1000 base pairs of 5 homology arm sequences, which is homologous to 500, 600, 700, 800, 900 or 1000 base pairs of sequences 5 of the genetic disruption (e.g., at TRAC locus), the transgene, and about 500, 600, 700, 800, 900 or 1000 base pairs of 3 homology arm sequences, which is homologous to 500, 600, 700, 800, 900 or 1000 base pairs of sequences 3 of the genetic disruption (e.g., at TRAC locus). In some embodiments, exemplary 5 and 3 homology arms for targeted integration at the TRAC locus are set forth in SEQ ID NOS: 1343 and 1344.

(836) In some embodiments, the template polynucleotide contains homology arms for targeting the endogenous TRBC1 or TRBC2 locus (exemplary nucleotide sequence of the human TRBC1 gene locus set forth in SEQ ID NO:349; NCBI Reference Sequence: NG_001333.2, TRBC1, described in Table 14 herein; exemplary nucleotide sequence of the human TRBC2 gene locus set forth in SEQ ID NO:1047; NCBI Reference Sequence: NG_001333.2, TRBC2, described in Table 15 herein). In some embodiments, the genetic disruption of the TRBC1 or TRBC2 locus is introduced at early coding region the gene, including sequence immediately following a transcription start site, within a first exon of the coding sequence, or within 500 bp of the transcription start site (e.g., less than 500, 450, 400, 350, 300, 250, 200, 150, 100 or 50 bp), or within 500 bp of the start codon (e.g., less than 500, 450, 400, 350, 300, 250, 200, 150, 100 or 50 bp). In some embodiments, the genetic disruption is introduced using any of the targeted nucleases and/or gRNAs described herein. In some embodiments, the template polynucleotide comprises about 500 to 1000, e.g., 600 to 900 or 700 to 800, base pairs of homology on either side of the genetic disruption introduced by the targeted nucleases and/or gRNAs. In some embodiments, the template polynucleotide comprises about 500, 600, 700, 800, 900 or 1000 base pairs of 5 homology arm sequences, which is homologous to 500, 600, 700, 800, 900 or 1000 base pairs of sequences 5 of the genetic disruption (e.g., at TRBC1 or TRBC2 locus), the transgene, and about 500, 600, 700, 800, 900 or 1000 base pairs of 3 homology arm sequences, which is homologous to 500, 600, 700, 800, 900 or 1000 base pairs of sequences 3 of the genetic disruption (e.g., at TRBC1 or TRBC2 locus).

(837) In some instances, the template polynucleotide comprises a promoter, e.g., a promoter that is exogenous and/or not present at or near the target locus. In some embodiments, the promoter drives expression only in a specific cell type (e.g., a T cell or B cell or NK cell specific promoter). In some embodiments in which the functional polypeptide encoding sequences are promoterless, expression of the integrated transgene is then ensured by transcription driven by an endogenous promoter or other control element in the region of interest.

(838) The transgene, including the transgene encoding the recombinant receptor or antigen-binding portion thereof or ? chain thereof and/or more additional transgene, can be inserted so that its expression is driven by the endogenous promoter at the integration site, namely the promoter that drives expression of the endogenous TCR gene to which it is inserted (e.g., TRAC, TRBC1 and/or TRBC2). For example, in some embodiments, the coding sequences in the transgene can be inserted without a promoter, but in-frame with the coding sequence of the endogenous target gene, such that expression of the integrated transgene is controlled by the transcription of the endogenous promoter at the integration site. In some embodiments, the transgene encoding the recombinant TCR or antigen-binding fragment or chain thereof and/or the one or more second transgene independently is operably linked to the endogenous promoter of the gene at the target site. In some embodiments, a ribosome skipping element/self-cleavage element, such as a 2A element, is placed upstream of the transgene coding sequence, such that the ribosome skipping element/self-cleavage element is placed in-frame with the endogenous gene. In some embodiments, the transgene encoding the recombinant TCR or antigen-binding fragment thereof or portion thereof is operably linked to the endogenous promoter of the gene at the target site (e.g., TRAC, TRBC1 and/or TRBC2).

(839) In some embodiments, the transgene may comprise a promoter and/or enhancer, for example a constitutive promoter or an inducible or tissue-specific promoter. In some embodiments, the promoter is or comprises a constitutive promoter. Exemplary constitutive promoters include, e.g., simian virus 40 early promoter (SV40), cytomegalovirus immediate-early promoter (CMV), human Ubiquitin C promoter (UBC), human elongation factor 1? promoter (EF1?), mouse phosphoglycerate kinase 1 promoter (PGK), and chicken ?-Actin promoter coupled with CMV early enhancer (CAGG). In some embodiments, the constitutive promoter is a synthetic or modified promoter. In some embodiments, the promoter is or comprises an MND promoter, a synthetic promoter that contains the U3 region of a modified MoMuLV LTR with myeloproliferative sarcoma virus enhancer (sequence set forth in SEQ ID NO: 1361 or 1347); see Challita et al. (1995) J. Virol. 69(2):748-755). In some embodiments, the promoter is a tissue-specific promoter. In another embodiment, the promoter is a viral promoter. In another embodiment, the promoter is a non-viral promoter. In some cases, the promoter is selected from among human elongation factor 1 alpha (EF1?) promoter (sequence set forth in SEQ ID NO: 1359 or 1360) or a modified form thereof (EF1? promoter with HTLV1 enhancer; sequence set forth in SEQ ID NO: 1345) or the MND promoter (sequence set forth in SEQ ID NO: 1361 or 1347. In some embodiments, the transgene does not include a regulatory element, e.g. promoter.

(840) The transgene may be inserted into an endogenous gene such that all, some or none of the endogenous gene is expressed. In some embodiments, the transgene (e.g., with or without peptide-encoding sequences) is integrated into any endogenous locus. In some embodiments, the transgene is integrated into the TRAC, TRBC1 and/or TRBC2 gene loci.

(841) Additionally, splice acceptor sequences may be included. Exemplary known splice acceptor site sequences include, e.g., CTGACCTCTTCTCTTCCTCCCACAG, (SEQ ID NO: 1357) (from the human HBB gene) and TTTCTCTCCACAG (SEQ ID NO: 1358) (from the human Immunoglobulin-gamma gene).

(842) In an exemplary embodiment, the template polynucleotide includes homology arms for targeting at the TRAC locus, regulatory sequences, e.g., promoter, and nucleic acid sequences encoding a recombinant receptor, e.g., TCR. In an exemplary embodiment, an additional template polynucleotide is employed, that includes homology arms for targeting at TRBC1 and/or TRBC2 loci, regulatory sequences, e.g., promoter, and nucleic acid sequences encoding another factor.

(843) In some embodiments, exemplary template polynucleotides contain transgene encoding a recombinant T cell receptor under the operable control of the human elongation factor 1 alpha (EF1?) promoter with HTLV1 enhancer (sequence set forth in SEQ ID NO: 1345) or the MND promoter (sequence set forth in SEQ ID NO: 1361 or 1347) or linked to nucleic acid sequences encoding a P2A ribosome skipping element (sequence set forth in SEQ ID NO:204) to drive expression of the recombinant TCR from the endogenous target gene locus (e.g., TRAC), 5 homology arm sequence of approximately 600 bp (e.g., set forth in SEQ ID NO: 1343), 3 homology arm sequence of approximately 600 bp (e.g., set forth in SEQ ID NO: 1344) that are homologous to sequences surrounding the target integration site in exon 1 of the human TCR ? constant region (TRAC) gene. In some embodiments, the template polynucleotide further contains other nucleic acid sequences, e.g., nucleic acid sequences encoding a marker, e.g., a surface marker or a selection marker. In some embodiments, the template polynucleotide further contains viral vector sequences, e.g., adeno-associated virus (AAV) vector sequences.

(844) In some embodiments, the transgene further encodes one or more marker(s). In some embodiments, the one or more marker(s) is a transduction marker, surrogate marker and/or a selection marker, including but not limited to any surrogate and/or selection marker described herein.

(845) In some embodiments, the polynucleotide, e.g., the template polynucleotide, comprises a nucleic acid sequence encoding a fraction and/or a portion of a recombinant receptor or chain thereof, e.g., a recombinant TCR or ? chain thereof and is targeted at a target site(s) that is within a gene locus that encodes an endogenous receptor, e.g., an endogenous gene encoding a TCR chain or domain. In certain embodiments, the nucleic acid sequence is targeted for in-frame integration within the endogenous gene locus. In particular embodiments, the in-frame integration results in a coding sequence for the recombinant receptor that contains the nucleic acid sequence encoding the portion and/or fragment of the recombinant receptor in frame with the portion and/or fragment of the gene locus that encodes the remaining portion and/or fragment of the receptor, such as to integrate exogenous and endogenous nucleic acid sequences to arrive at a coding sequence encoding a complete, whole, and/or full length recombinant receptor. In certain embodiments, the integration genetically disrupts expression of the endogenous receptor encoded by gene at the target site. In particular embodiments, the transgene encoding the portion of the recombinant receptor is targeted within the gene locus via HDR.

(846) In some embodiments, the transgene encodes a portion of the recombinant TCR and is integrated in-frame into an endogenous open reading frame and/or gene locus encoding ? chain or a domain of a TCR. In certain embodiments, the transgene encodes a portion of a recombinant TCR and is inserted in-frame within an endogenous open reading frame encoding a TCR constant domain. In some embodiments, the integration of the transgene into the locus modifies and/or results in a modified locus that encodes the full recombinant TCR. In particular embodiments, a portion of the encoded recombinant TCR is encoded by a nucleic acid sequence present in the transgene, and the remaining portion of the recombinant TCR is encoded by a nucleic acid sequence present in the open reading frame of the endogenous gene encoding TCR? or TCR? constant domains (e.g., described in Tables 13-15 herein). In particular embodiments, the transcription of the modified locus results in an mRNA that encodes the recombinant TCR. In particular embodiments, a portion of the mRNA is transcribed from a nucleic acid sequence present in the transgene, and the remaining or further portion of the mRNA is transcribed from a nucleic acid sequence present in the open reading frame of the endogenous gene. In some embodiments, the transgene is integrated at a target site immediately upstream of and in frame with of the region or portion of the open reading frame that encodes the remaining portion of the recombinant TCR.

(847) In particular embodiments, the modified TRAC or TRBC locus includes nucleic acid sequences encoding a recombinant TCR. In some aspects, the modified TRAC or TRBC locus in the genetically engineered cell comprises a transgene sequence (also referred to herein as exogenous or heterologous nucleic acid sequences) encoding a portion of a recombinant TCR, integrated into an endogenous TRAC or TRBC locus, which normally encodes a TCR? or TCR? constant domain. In some embodiments, the methods involve inducing a targeted genetic disruption and homology-dependent repair (HDR), using template polynucleotides containing the transgene encoding a portion of the recombinant TCR, thereby targeting integration of the transgene at the TRAC or TRBC locus.

(848) In some embodiments, the transgene sequence encoding a portion of the recombinant TCR contains a sequence of nucleotides encoding a TCR? chain and a portion of a TCR? chain. In some embodiments, the portion of the TCR? chain encoded by the transgene sequences comprises less than a full length of the TCR? chain. In particular embodiments, the portion of the TCR? chain contains a TCR? variable domain and a portion of a TCR? constant domain that is less than a full length TCR? constant domain, e.g., a full length native TCR? constant domain, or does not contain a sequence encoding the TCR? constant domain. In some aspects, upon integration of the transgene sequence into the endogenous TRAC locus, the resulting modified TRAC locus encodes a recombinant TCR receptor, encoded by a fusion of the transgene, targeted by HDR, and an open reading frame or a partial sequence thereof of an endogenous TRAC locus. In some embodiments, the encoded recombinant TCR contains a TCR? chain, e.g., a functional TCR? chain that is capable of binding to a TCR? chain.

(849) In particular embodiments, the transgene sequence encoding a portion of the recombinant TCR contains a sequence of nucleotides encoding a TCR? chain and a portion of a TCR? chain. In some embodiments, the portion of the TCR? chain encoded by the transgene sequences is or includes less than a full length of the TCR? chain. In particular embodiments, the portion of the TCR? chain contains a TCR? variable domain and a portion of a TCR? constant domain that is less than a full length TCR? constant domain, e.g., a full length native TCR? constant domain, or does not contain a sequence encoding the TCR? constant domain. In some aspects, upon integration of the transgene sequence into the endogenous TRBC locus, e.g., a TRBC1 and/or TRBC2 locus, the resulting modified TRBC locus encodes a recombinant TCR receptor, encoded by a fusion of the transgene, targeted by HDR, and an open reading frame or a partial sequence thereof of an endogenous TRBC locus. In some embodiments, the encoded recombinant TCR contains a TCR? chain, e.g., a functional TCR? chain that is capable of binding to a TCR? chain.

(850) In particular embodiments, the recombinant receptor is a recombinant TCR or chain thereof that contains one or more variable domains and one or more constant domains. In particular embodiments, the transgene encodes the portion and/or fragment of the recombinant TCR that does not include a TCR constant domain, and the transgene is integrated in-frame with the sequence, e.g., genomic DNA sequence, encoding the endogenous TCR constant domain. In certain embodiments, the integration results in a coding sequence that encodes the complete, whole, and/or full length recombinant TCR or chain thereof. In some embodiments, the coding sequence contains the transgene sequence encoding the portion or fragment of the TCR or chain thereof and an endogenous sequence encoding the endogenous TCR constant domain.

(851) In some embodiments the portion of the recombinant TCR comprises a full length TCR? chain (including TCR? variable domain and TCR? constant domain), a TCR? variable domain, and a portion of a TCR? constant domain. In certain embodiments, the transgene is inserted or integrated into the TRAC locus, e.g. a TRAC open reading frame, at a target site, resulting in an in-frame insertion of the transgene with the region or portion of the open reading frame encoding the endogenous remaining portion of the TCR? constant domain. In certain embodiments, the insertion results in a modified TRAC locus encoding the full recombinant TCR. In some embodiments, the modified TRAC locus encodes a recombinant TCR, of which a portion is encoded by the nucleic acid sequence of the transgene, such as a portion that includes the full length TCR? chain (including TCR? variable domain and TCR? constant domain), a TCR? variable domain, and a portion of a TCR? constant domain and the remaining or further portion, such as the remaining or further portion of the TCR? constant domain, is encoded by an endogenous and/or native TRAC sequence. In certain embodiments, the endogenous and/or native TRAC sequence encodes the remaining portion of the recombinant TCR. In some embodiments; the template polynucleotide further contains other nucleic acid sequences, e.g., nucleic acid sequences encoding a marker, e.g., a surface marker or a selection marker. In some embodiments, the template polynucleotide further contains viral vector sequences, e.g., adeno-associated virus (AAV) vector sequences.

(852) In some embodiments, the polynucleotide, e.g., a polynucleotide such as a template polynucleotide encoding the recombinant T cell receptor, are introduced into the cells in nucleotide form, e.g., as a polynucleotide or a vector. In some embodiments, the template polynucleotide is introduced into the cell for engineering, in addition to the agent(s) capable of inducing a targeted genetic disruption, e.g., nuclease and/or gRNAs. In some embodiments, the template polynucleotide(s) may be delivered prior to, simultaneously or after the agent(s) capable of inducing a targeted genetic disruption is introduced into a cell. In some embodiments, the template polynucleotide(s) are delivered simultaneously with the agents. In some embodiments, the template polynucleotides are delivered prior to the agents, for example, seconds to hours to days before the template polynucleotides, including, but not limited to, 1 to 60 minutes (or any time there between) before the agents, 1 to 24 hours (or any time there between) before the agents or more than 24 hours before the agents. In some embodiments, the template polynucleotides are delivered after the agents, seconds to hours to days after the template polynucleotides, including immediately after delivery of the agent, e.g., between 1 minute to 4 hours, such as about 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes, 60 minutes, 90 minutes, 2 hours, 3 hours or 4 hours after delivery of the agents and/or preferably within 4 hours of delivery of the agents. In some embodiments, the template polynucleotide is delivered more than 4 hours after delivery of the agents.

(853) In some embodiments, the template polynucleotides may be delivered using the same delivery systems as the agent(s) capable of inducing a targeted genetic disruption, e.g., nuclease and/or gRNAs. In some embodiments, the template polynucleotides may be delivered using different same delivery systems as the agent(s) capable of inducing a targeted genetic disruption, e.g., nuclease and/or gRNAs. In some embodiments, the template polynucleotide is delivered simultaneously with the agent(s). In other embodiments, the template polynucleotide is delivered at a different time, before or after delivery of the agent(s). In certain embodiments, any suitable method known for introducing a polynucleotide into a cell may be used to deliver agents and/or template DNA, including those described herein.

(854) In particular embodiments, the polynucleotide, e.g., the template polynucleotide, are introduced into the cells in nucleotide form, e.g., as or within a non-viral vector. In some embodiments, the non-viral vector is or includes a polynucleotide, e.g., a DNA or RNA polynucleotide, that is suitable for transduction and/or transfection by any suitable and/or known non-viral method for gene delivery, such as but not limited to microinjection, electroporation, transient cell compression or squeezing (e.g., as described in Lee, et al. (2012) Nano Lett 12: 6322-27), lipid-mediated transfection, peptide-mediated delivery, e.g., cell-penetrating peptides, or a combination thereof.

(855) In some embodiments, the template polynucleotide sequence can be comprised in a vector molecule containing sequences that are not homologous to the region of interest in the genomic DNA. In some embodiments, the virus is a DNA virus (e.g., dsDNA or ssDNA virus). In some embodiments, the virus is an RNA virus (e.g., an ssRNA virus). Exemplary viral vectors/viruses include, e.g., retroviruses, lentiviruses, adenovirus, adeno-associated virus (AAV), vaccinia viruses, poxviruses, and herpes simplex viruses, or any of the viruses described elsewhere herein.

(856) In some embodiments, the template polynucleotide can be transferred into cells using recombinant infectious virus particles, such as, e.g., vectors derived from simian virus 40 (SV40), adenoviruses, adeno-associated virus (AAV). In some embodiments, the template polynucleotide are transferred into T cells using recombinant lentiviral vectors or retroviral vectors, such as gamma-retroviral vectors (see, e.g., Koste et al. (2014) Gene Therapy 2014 Apr. 3. doi: 10.1038/gt.2014.25; Carlens et al. (2000) Exp Hematol 28(10): 1137-46; Alonso-Camino et al. (2013) Mol Ther Nucl Acids 2, e93; Park et al., Trends Biotechnol. 2011 Nov. 29(11): 550-557 or HIV-1 derived lentiviral vectors.

(857) In some embodiments, the retroviral vector has a long terminal repeat sequence (LTR), e.g., a retroviral vector derived from the Moloney murine leukemia virus (MoMLV), myeloproliferative sarcoma virus (MPSV), murine embryonic stem cell virus (MESV), murine stem cell virus (MSCV), or spleen focus forming virus (SFFV). Most retroviral vectors are derived from murine retroviruses. In some embodiments, the retroviruses include those derived from any avian or mammalian cell source. The retroviruses typically are amphotropic, meaning that they are capable of infecting host cells of several species, including humans. In one embodiment, the gene to be expressed replaces the retroviral gag, pol and/or env sequences. A number of illustrative retroviral systems have been described (e.g., U.S. Pat. Nos. 5,219,740; 6,207,453; 5,219,740; Miller and Rosman (1989) BioTechniques 7:980-990; Miller, A. D. (1990) Human Gene Therapy 1:5-14; Scarpa et al. (1991) Virology 180:849-852; Burns et al. (1993) Proc. Natl. Acad. Sci. USA 90:8033-8037; and Boris-Lawrie and Temin (1993) Cur. Opin. Genet. Develop. 3:102-109).

(858) In other aspects, the template polynucleotide is delivered by viral and/or non-viral gene transfer methods. In some embodiments, the template polynucleotide is delivered to the cell via an adeno associated virus (AAV). Any AAV vector can be used, including, but not limited to, AAV1, AAV2, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8 and combinations thereof. In some instances, the AAV comprises LTRs that are of a heterologous serotype in comparison with the capsid serotype (e.g., AAV2 ITRs with AAV5, AAV6, or AAV8 capsids). The template polynucleotide may be delivered using the same gene transfer system as used to deliver the nuclease (including on the same vector) or may be delivered using a different delivery system that is used for the nuclease. In some embodiments, the template polynucleotide is delivered using a viral vector (e.g., AAV) and the nuclease(s) is(are) delivered in mRNA form. The cell may also be treated with one or more molecules that inhibit binding of the viral vector to a cell surface receptor as described herein prior to, simultaneously and/or after delivery of the viral vector (e.g., carrying the nuclease(s) and/or template polynucleotide).

(859) In some embodiments, the one or more agent(s) and the template polynucleotide are delivered in the same format or method. For example, in some embodiments, the one or more agent(s) and the template polynucleotide are both comprised in a vector, e.g., viral vector. In some embodiments, the template polynucleotide is encoded on the same vector backbone, e.g. AAV genome, plasmid DNA, as the Cas9 and gRNA. In some aspects, the one or more agent(s) and the template polynucleotide are in different formats, e.g., ribonucleic acid-protein complex (RNP) for the Cas9-gRNA agent and a linear DNA for the template polynucleotide, but they are delivered using the same method. In some embodiments, the template polynucleotides and nucleases may be on the same vector, for example an AAV vector (e.g., AAV6). In some embodiments, the template polynucleotides are delivered using an AAV vector and the agent(s) capable of inducing a targeted genetic disruption, e.g., nuclease and/or gRNAs are delivered as a different form, e.g., as mRNAs encoding the nucleases and/or gRNAs. In some embodiments, the template polynucleotides and nucleases are delivered using the same type of method, e.g., a viral vector, but on separate vectors. In some embodiments, the template polynucleotides are delivered in a different delivery system as the agents capable of inducing a genetic disruption, e.g., nucleases and/or gRNAs. In some embodiments, the template polynucleotide is excised from a vector backbone in vivo, e.g., it is flanked by gRNA recognition sequences. In some embodiments, the template polynucleotide is on a separate polynucleotide molecule as the Cas9 and gRNA. In some embodiments, the Cas9 and the gRNA are introduced in the form of a ribonucleoprotein (RNP) complex, and the template polynucleotide is introduced as a polynucleotide molecule, e.g., in a vector or a linear nucleic acid molecule, e.g., linear DNA. Types or nucleic acids and vectors for delivery include any of those described herein.

VI. Compositions, Methods, and Uses

(860) Also provided are compositions including the binding molecules, e.g. TCRs, and engineered cells, including pharmaceutical compositions and formulations, and methods of using and uses of the molecules and compositions, such as in the treatment of diseases, conditions, and disorders in which HPV16 E6 or E7 is expressed, and/or detection, diagnostic, and prognostic methods.

(861) A. Pharmaceutical Compositions and Formulations

(862) Provided are pharmaceutical formulations including the binding molecules, e.g., TCR or antigen binding fragment thereof or antibody or antigen-binding fragment thereof, and/or the engineered cells expressing the binding molecules. The pharmaceutical compositions and formulations generally include one or more optional pharmaceutically acceptable carrier or excipient. In some embodiments, the composition includes at least one additional therapeutic agent.

(863) The term pharmaceutical formulation refers to a preparation which is in such form as to permit the biological activity of an active ingredient contained therein to be effective, and which contains no additional components which are unacceptably toxic to a subject to which the formulation would be administered.

(864) A pharmaceutically acceptable carrier refers to an ingredient in a pharmaceutical formulation, other than an active ingredient, which is nontoxic to a subject. A pharmaceutically acceptable carrier includes, but is not limited to, a buffer, excipient, stabilizer, or preservative.

(865) In some aspects, the choice of carrier is determined in part by the particular cell or binding molecule, and/or by the method of administration. Accordingly, there are a variety of suitable formulations. For example, the pharmaceutical composition can contain preservatives. Suitable preservatives may include, for example, methylparaben, propylparaben, sodium benzoate, and benzalkonium chloride. In some aspects, a mixture of two or more preservatives is used. The preservative or mixtures thereof are typically present in an amount of about 0.0001% to about 2% by weight of the total composition. Carriers are described, e.g., by Remington's Pharmaceutical Sciences 16th edition, Osol, A. Ed. (1980). Pharmaceutically acceptable carriers are generally nontoxic to recipients at the dosages and concentrations employed, and include, but are not limited to: buffers such as phosphate, citrate, and other organic acids; antioxidants including ascorbic acid and methionine; preservatives (such as octadecyldimethylbenzyl ammonium chloride; hexamethonium chloride; benzalkonium chloride; benzethonium chloride; phenol, butyl or benzyl alcohol; alkyl parabens such as methyl or propyl paraben; catechol; resorcinol; cyclohexanol; 3-pentanol; and m-cresol); low molecular weight (less than about 10 residues) polypeptides; proteins, such as serum albumin, gelatin, or immunoglobulins; hydrophilic polymers such as polyvinylpyrrolidone; amino acids such as glycine, glutamine, asparagine, histidine, arginine, or lysine; monosaccharides, disaccharides, and other carbohydrates including glucose, mannose, or dextrins; chelating agents such as EDTA; sugars such as sucrose, mannitol, trehalose or sorbitol; salt-forming counter-ions such as sodium; metal complexes (e.g. Zn-protein complexes); and/or non-ionic surfactants such as polyethylene glycol (PEG).

(866) Buffering agents in some aspects are included in the compositions. Suitable buffering agents include, for example, citric acid, sodium citrate, phosphoric acid, potassium phosphate, and various other acids and salts. In some aspects, a mixture of two or more buffering agents is used. The buffering agent or mixtures thereof are typically present in an amount of about 0.001% to about 4% by weight of the total composition. Methods for preparing administrable pharmaceutical compositions are known. Exemplary methods are described in more detail in, for example, Remington: The Science and Practice of Pharmacy, Lippincott Williams & Wilkins; 21st ed. (May 1, 2005).

(867) Formulations of the binding molecules can include lyophilized formulations and aqueous solutions. The formulation or composition may also contain more than one active ingredient useful for the particular indication, disease, or condition being treated with the binding molecules or cells, preferably those with activities complementary to the binding molecule or cell, where the respective activities do not adversely affect one another. Such active ingredients are suitably present in combination in amounts that are effective for the purpose intended. Thus, in some embodiments, the pharmaceutical composition further includes other pharmaceutically active agents or drugs, such as chemotherapeutic agents, e.g., asparaginase, busulfan, carboplatin, cisplatin, daunorubicin, doxorubicin, fluorouracil, gemcitabine, hydroxyurea, methotrexate, paclitaxel, rituximab, vinblastine, vincristine, etc. In some embodiments, the cells or binding molecules are administered in the form of a salt, e.g., a pharmaceutically acceptable salt. Suitable pharmaceutically acceptable acid addition salts include those derived from mineral acids, such as hydrochloric, hydrobromic, phosphoric, metaphosphoric, nitric, and sulphuric acids, and organic acids, such as tartaric, acetic, citric, malic, lactic, fumaric, benzoic, glycolic, gluconic, succinic, and arylsulphonic acids, for example, p-toluenesulphonic acid.

(868) Active ingredients may be entrapped in microcapsules, in colloidal drug delivery systems (for example, liposomes, albumin microspheres, microemulsions, nano-particles and nanocapsules) or in macroemulsions. In certain embodiments, the pharmaceutical composition is formulated as an inclusion complex, such as cyclodextrin inclusion complex, or as a liposome. Liposomes can serve to target the host cells (e.g., T-cells or NK cells) to a particular tissue. Many methods are available for preparing liposomes, such as those described in, for example, Szoka et al., Ann. Rev. Biophys. Bioeng., 9: 467 (1980), and U.S. Pat. Nos. 4,235,871, 4,501,728, 4,837,028, and 5,019,369.

(869) The pharmaceutical composition in some aspects can employ time-released, delayed release, and sustained release delivery systems such that the delivery of the composition occurs prior to, and with sufficient time to cause, sensitization of the site to be treated. Many types of release delivery systems are available and known. Such systems can avoid repeated administrations of the composition, thereby increasing convenience to the subject and the physician.

(870) The pharmaceutical composition in some embodiments contains the binding molecules and/or cells in amounts effective to treat or prevent the disease or condition, such as a therapeutically effective or prophylactically effective amount. Therapeutic or prophylactic efficacy in some embodiments is monitored by periodic assessment of treated subjects. For repeated administrations over several days or longer, depending on the condition, the treatment is repeated until a desired suppression of disease symptoms occurs. However, other dosage regimens may be useful and can be determined. The desired dosage can be delivered by a single bolus administration of the composition, by multiple bolus administrations of the composition, or by continuous infusion administration of the composition.

(871) In certain embodiments, in the context of genetically engineered cells containing the binding molecules, a subject is administered the range of about one million to about 100 billion cells, such as, e.g., 1 million to about 50 billion cells (e.g., about 5 million cells, about 25 million cells, about 500 million cells, about 1 billion cells, about 5 billion cells, about 20 billion cells, about 30 billion cells, about 40 billion cells, or a range defined by any two of the foregoing values), such as about 10 million to about 100 billion cells (e.g., about 20 million cells, about 30 million cells, about 40 million cells, about 60 million cells, about 70 million cells, about 80 million cells, about 90 million cells, about 10 billion cells, about 25 billion cells, about 50 billion cells, about 75 billion cells, about 90 billion cells, or a range defined by any two of the foregoing values), and in some cases about 100 million cells to about 50 billion cells (e.g., about 120 million cells, about 250 million cells, about 350 million cells, about 450 million cells, about 650 million cells, about 800 million cells, about 900 million cells, about 3 billion cells, about 30 billion cells, about 45 billion cells) or any value in between these ranges, and/or such a number of cells per kilogram of body weight of the subject.

(872) The cells or binding molecules may be administered using standard administration techniques, formulations, and/or devices. Provided are formulations and devices, such as syringes and vials, for storage and administration of the compositions. Administration of the cells can be autologous or heterologous. For example, immunoresponsive cells or progenitors can be obtained from one subject, and administered to the same subject or a different, compatible subject. Peripheral blood derived immunoresponsive cells or their progeny (e.g., in vivo, ex vivo or in vitro derived) can be administered via localized injection, including catheter administration, systemic injection, localized injection, intravenous injection, or parenteral administration. When administering a therapeutic composition (e.g., a pharmaceutical composition containing a genetically modified immunoresponsive cell), it will generally be formulated in a unit dosage injectable form (solution, suspension, emulsion).

(873) Formulations include those for oral, intravenous, intraperitoneal, subcutaneous, pulmonary, transdermal, intramuscular, intranasal, buccal, sublingual, or suppository administration. In some embodiments, the cell populations are administered parenterally. The term parenteral, as used herein, includes intravenous, intramuscular, subcutaneous, rectal, vaginal, intracranial, intrathoracic, and intraperitoneal administration. In some embodiments, the cell populations are administered to a subject using peripheral systemic delivery by intravenous, intraperitoneal, or subcutaneous injection.

(874) Compositions in some embodiments are provided as sterile liquid preparations, e.g., isotonic aqueous solutions, suspensions, emulsions, dispersions, or viscous compositions, which may in some aspects be buffered to a selected pH. Liquid preparations are normally easier to prepare than gels, other viscous compositions, and solid compositions. Additionally, liquid compositions are somewhat more convenient to administer, especially by injection. Viscous compositions, on the other hand, can be formulated within the appropriate viscosity range to provide longer contact periods with specific tissues. Liquid or viscous compositions can comprise carriers, which can be a solvent or dispersing medium containing, for example, water, saline, phosphate buffered saline, polyol (for example, glycerol, propylene glycol, liquid polyethylene glycol) and suitable mixtures thereof.

(875) Sterile injectable solutions can be prepared by incorporating the binding molecule in a solvent, such as in admixture with a suitable carrier, diluent, or excipient such as sterile water, physiological saline, glucose, dextrose, or the like. The compositions can also be lyophilized. The compositions can contain auxiliary substances such as wetting, dispersing, or emulsifying agents (e.g., methylcellulose), pH buffering agents, gelling or viscosity enhancing additives, preservatives, flavoring agents, colors, and the like, depending upon the route of administration and the preparation desired. Standard texts may in some aspects be consulted to prepare suitable preparations.

(876) Various additives which enhance the stability and sterility of the compositions, including antimicrobial preservatives, antioxidants, chelating agents, and buffers, can be added. Prevention of the action of microorganisms can be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin.

(877) Sustained-release preparations may be prepared. Suitable examples of sustained-release preparations include semipermeable matrices of solid hydrophobic polymers containing the antibody, which matrices are in the form of shaped articles, e.g. films, or microcapsules.

(878) The formulations to be used for in vivo administration are generally sterile. Sterility may be readily accomplished, e.g., by filtration through sterile filtration membranes.

(879) B. Therapeutic and Prophylactic Methods and Uses

(880) Also provided are methods of administering and uses, such as therapeutic and prophylactic uses, of the binding molecules, including TCRs and antigen-binding fragments thereof and antibodies or antigen-binding fragments thereof, and/or engineered cells expressing the binding molecules. Such methods and uses include therapeutic methods and uses, for example, involving administration of the molecules, cells, or compositions containing the same, to a subject having a disease, condition, or disorder expressing or associated with HPV, e.g., HPV16, and/or in which cells or tissues express, e.g., specifically express, HPV16, e.g., HPV16 E6 or E7. In some embodiments, the molecule, cell, and/or composition is administered in an effective amount to effect treatment of the disease or disorder. Uses include uses of the binding molecules and cells in such methods and treatments, and in the preparation of a medicament in order to carry out such therapeutic methods. In some embodiments, the methods are carried out by administering the binding molecules or cells, or compositions comprising the same, to the subject having, having had, or suspected of having the disease or condition. In some embodiments, the methods thereby treat the disease or condition or disorder in the subject.

(881) As used herein, treatment (and grammatical variations thereof such as treat or treating) refers to complete or partial amelioration or reduction of a disease or condition or disorder, or a symptom, adverse effect or outcome, or phenotype associated therewith. Desirable effects of treatment include, but are not limited to, preventing occurrence or recurrence of disease, alleviation of symptoms, diminishment of any direct or indirect pathological consequences of the disease, preventing metastasis, decreasing the rate of disease progression, amelioration or palliation of the disease state, and remission or improved prognosis. The terms do not imply complete curing of a disease or complete elimination of any symptom or effect(s) on all symptoms or outcomes.

(882) As used herein, delaying development of a disease means to defer, hinder, slow, retard, stabilize, suppress and/or postpone development of the disease (such as cancer). This delay can be of varying lengths of time, depending on the history of the disease and/or individual being treated. As is evident to one skilled in the art, a sufficient or significant delay can, in effect, encompass prevention, in that the individual does not develop the disease. For example, a late stage cancer, such as development of metastasis, may be delayed.

(883) Preventing, as used herein, includes providing prophylaxis with respect to the occurrence or recurrence of a disease in a subject that may be predisposed to the disease but has not yet been diagnosed with the disease. In some embodiments, the provided molecules and compositions are used to delay development of a disease or to slow the progression of a disease.

(884) As used herein, to suppress a function or activity is to reduce the function or activity when compared to otherwise same conditions except for a condition or parameter of interest, or alternatively, as compared to another condition. For example, a binding molecule or composition or cell which suppresses tumor growth reduces the rate of growth of the tumor compared to the rate of growth of the tumor in the absence of the binding molecule or composition or cell.

(885) An effective amount of an agent, e.g., a pharmaceutical formulation, binding molecule, or cells, or composition, in the context of administration, refers to an amount effective, at dosages/amounts and for periods of time necessary, to achieve a desired result, such as a therapeutic or prophylactic result.

(886) A therapeutically effective amount of an agent, e.g., a pharmaceutical formulation, binding molecule, or cells, refers to an amount effective, at dosages and for periods of time necessary, to achieve a desired therapeutic result, such as for treatment of a disease, condition, or disorder, and/or pharmacokinetic or pharmacodynamic effect of the treatment. The therapeutically effective amount may vary according to factors such as the disease state, age, sex, and weight of the subject, and the populations of cells administered. In some embodiments, the provided methods involve administering the binding molecules, cells, and/or compositions at effective amounts, e.g., therapeutically effective amounts.

(887) A prophylactically effective amount refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired prophylactic result. Typically but not necessarily, since a prophylactic dose is used in subjects prior to or at an earlier stage of disease, the prophylactically effective amount will be less than the therapeutically effective amount.

(888) As used herein, a subject is a mammal, such as a human or other animal, and typically is human.

(889) Among the diseases to be treated are cancers, typically HPV-associated cancers, and any HPV-associated, e.g., HPV 16-associated, diseases or conditions or diseases or conditions in which an HPV oncoprotein, e.g., E6 or E7, such as an HPV 16 oncoprotein, e.g., HPV 16 E6 or E7 is expressed. In certain diseases and conditions, the viral protein such as the oncoprotein such as the HPV 16 E6 or E7 is expressed in or by malignant cells and cancers, and/or a peptide epitope thereof is expressed on such malignant cancers or tissues, such as by way of MHC presentation. In some embodiments, the disease or condition is an HPV16-expressing cancer. In some embodiments, the cancer is a carcinoma, melanoma or other precancerous or cancerous state caused by or otherwise associated with HPV, such as HPV-16. In some embodiments, the carcinoma can be a squamous cell or adenocarionma. In some embodiments, the disease or condition can be characterized by an epithelial cell abnormality associated with oncogenic HPV infection, such as koilocytosis; hyperkeratosis; precancerous conditions encompassing intraepithelial neoplasias or intraepithelial lesion; high-grade dysplasias; and invasive or malignant cancers. Among the HPV 16-associated diseases or conditions that can be treated include, but are not limited to, cervical cancer, uterine cancer, anal cancer, colorectal cancer, vaginal cancer, vulvar cancer, penile cancer, oropharyngeal cancers, tonsil cancer, pharyngeal cancers (pharynx cancer), laryngeal cancer (larynx cancer), oral cancer, skin cancer, esophageal cancer, head and neck cancer such as a squamous cell carcinoma (SCC) head and neck cancer, or small cell lung cancer. In some embodiments, the disease or condition is a cervical carcinoma.

(890) In some embodiments, the methods may include steps or features to identify a subject who has, is suspected to have, or is at risk for developing an HPV 16-associated disease or disorder (see e.g. U.S. Pat. Nos. 6,355,424 and 8,968,995) and/or the subject to be treated may be a subject identified to have or to be so at risk for having or developing such HPV-associated disease or condition or cancer. Hence, provided in some aspects are methods for identifying subjects with diseases or disorders associated with HPV 16 E6 or E7 expression and selecting them for treatment and/or treating such subjects, e.g., selectively treating such subjects, with a provided HPV 16 binding molecule, including in some aspects with cells engineered to express such binding molecules, including in some aspects any of the HPV 16 E6 or E7 TCRs or antigen binding fragments thereof or anti-HPV 16 E6 or E7 antibodies, e.g., antibody fragments and proteins containing the same, such as the chimeric receptors, e.g., TCR-like CARs, and/or engineered cells expressing the TCRs or CARs.

(891) For example, a subject may be screened for the presence of a disease or disorder associated with HPV 16 E6 or E7 expression, such as an HPV 16 E6- or E7-expressing cancer. In some embodiments, the methods include screening for or detecting the presence of an HPV 16 E6- or E7-associated disease, e.g. a tumor. Thus, in some aspects, a sample may be obtained from a patient suspected of having a disease or disorder associated with HPV 16 E6 or E7 expression and assayed for the expression level of HPV 16 E6 or E7. In some aspects, a subject who tests positive for an HPV 16 E6- or E7-associated disease or disorder may be selected for treatment by the present methods, and may be administered a therapeutically effective amount of a binding molecule described herein, a CAR expressing such a binding molecule, cells containing the binding molecule, or a pharmaceutical composition thereof as described herein. In some embodiments, the methods can be used to monitor the size or density of an HPV 16 E6- or E7-expressing tissue, e.g. tumor, over time, e.g., before, during, or after treatment by the methods. In some aspects, subjects treated by methods provided herein have been selected or tested positive for HPV expression according to such methods, e.g., prior to initiation of or during treatment.

(892) In some embodiments, administration of a provided HPV 16 binding molecule, including any of the HPV 16 E6 or E7 TCRs or antigen binding fragments thereof or anti-HPV 16 E6 or E7 antibodies, e.g., antibody fragments and proteins containing the same, such as the chimeric receptors, e.g., TCR-like CARs, and/or engineered cells expressing the TCRs or CARs, can be combined with another therapeutic for the treatment of an HPV disease. For example, the additional therapeutic treatment can include treatment with another anti-cancer agent for the treatment of cervical cancer. Suitable dosages for such a co-administered agent may be lowered due to the combined action (synergy) of the agent and the provide HPV 16 binding molecule.

(893) In some embodiments, the subject has persistent or relapsed disease, e.g., following treatment with another HPV 16-specific binding molecule and/or cells expressing an HPV 16-targeting binding molecule and/or other therapy, including chemotherapy, radiation, and/or hematopoietic stem cell transplantation (HSCT), e.g., allogenic HSCT. In some embodiments, the administration effectively treats the subject despite the subject having become resistant to another HPV 16-targeted therapy. In some embodiments, the subject has not relapsed but is determined to be at risk for relapse, such as at a high risk of relapse, and thus the compound or composition is administered prophylactically, e.g., to reduce the likelihood of or prevent relapse.

(894) In some embodiments, the treatment does not induce an immune response by the subject to the therapy, and/or does not induce such a response to a degree that prevents effective treatment of the disease or condition. In some aspects, the degree of immunogenicity and/or graft versus host response is less than that observed with a different but comparable treatment. For example, in the case of adoptive cell therapy using cells expressing TCRs or CARs including the provided binding molecules, the degree of immunogenicity in some embodiments is reduced compared to TCRs or CARs including a different binding molecule.

(895) In some embodiments, the methods include adoptive cell therapy, whereby genetically engineered cells expressing the provided binding molecules are administered to subjects. Such administration can promote activation of the cells (e.g., T cell activation) in an HPV 16-targeted manner, such that the cells of the disease or disorder are targeted for destruction.

(896) Thus, the provided methods and uses include methods and uses for adoptive cell therapy. In some embodiments, the methods include administration of the cells or a composition containing the cells to a subject, tissue, or cell, such as one having, at risk for, or suspected of having the disease, condition or disorder. In some embodiments, the cells, populations, and compositions are administered to a subject having the particular disease or condition to be treated, e.g., via adoptive cell therapy, such as adoptive T cell therapy. In some embodiments, the cells or compositions are administered to the subject, such as a subject having or at risk for the disease or condition. In some aspects, the methods thereby treat, e.g., ameliorate one or more symptom of the disease or condition, such as by lessening tumor burden in an HPV 16 E6- or E7-expressing cancer.

(897) Methods for administration of cells for adoptive cell therapy are known and may be used in connection with the provided methods and compositions. For example, adoptive T cell therapy methods are described, e.g., in US Patent Application Publication No. 2003/0170238 to Gruenberg et al; U.S. Pat. No. 4,690,915 to Rosenberg; Rosenberg (2011) Nat Rev Clin Oncol. 8(10):577-85). See, e.g., Themeli et al. (2013) Nat Biotechnol. 31(10): 928-933; Tsukahara et al. (2013) Biochem Biophys Res Commun 438(1): 84-9; Davila et al. (2013) PLoS ONE 8(4): e61338.

(898) In some embodiments, the cell therapy, e.g., adoptive cell therapy, e.g., adoptive T cell therapy, is carried out by autologous transfer, in which the cells are isolated and/or otherwise prepared from the subject who is to receive the cell therapy, or from a sample derived from such a subject. Thus, in some aspects, the cells are derived from a subject, e.g., patient, in need of a treatment and the cells, following isolation and processing are administered to the same subject.

(899) In some embodiments, the cell therapy, e.g., adoptive cell therapy, e.g., adoptive T cell therapy, is carried out by allogeneic transfer, in which the cells are isolated and/or otherwise prepared from a subject other than a subject who is to receive or who ultimately receives the cell therapy, e.g., a first subject. In such embodiments, the cells then are administered to a different subject, e.g., a second subject, of the same species. In some embodiments, the first and second subjects are genetically identical. In some embodiments, the first and second subjects are genetically similar. In some embodiments, the second subject expresses the same HLA class or supertype as the first subject.

(900) In some embodiments, the subject, to whom the cells, cell populations, or compositions are administered, is a primate, such as a human. In some embodiments, the primate is a monkey or an ape. The subject can be male or female and can be any suitable age, including infant, juvenile, adolescent, adult, and geriatric subjects. In some embodiments, the subject is a non-primate mammal, such as a rodent. In some examples, the patient or subject is a validated animal model for disease, adoptive cell therapy, and/or for assessing toxic outcomes such as cytokine release syndrome (CRS).

(901) The provided binding molecules, such as TCRs and antigen-binding fragments thereof and antibodies and antigen-binding fragments thereof, and cells expressing the same, can be administered by any suitable means, for example, by injection, e.g., intravenous or subcutaneous injections, intraocular injection, periocular injection, subretinal injection, intravitreal injection, trans-septal injection, subscleral injection, intrachoroidal injection, intracameral injection, subconjectval injection, subconjuntival injection, sub-Tenon's injection, retrobulbar injection, peribulbar injection, or posterior juxtascleral delivery. In some embodiments, they are administered by parenteral, intrapulmonary, and intranasal, and, if desired for local treatment, intralesional administration. Parenteral infusions include intramuscular, intravenous, intraarterial, intraperitoneal, intracranial, intrathoracic, or subcutaneous administration. Dosing and administration may depend in part on whether the administration is brief or chronic. Various dosing schedules include but are not limited to single or multiple administrations over various time-points, bolus administration, and pulse infusion.

(902) For the prevention or treatment of disease, the appropriate dosage of the binding molecule or cell may depend on the type of disease to be treated, the type of binding molecule, the severity and course of the disease, whether the binding molecule is administered for preventive or therapeutic purposes, previous therapy, the patient's clinical history and response to the binding molecule, and the discretion of the attending physician. The compositions and molecules and cells are in some embodiments suitably administered to the patient at one time or over a series of treatments.

(903) In certain embodiments, in the context of genetically engineered cells containing the binding molecules, a subject is administered the range of about one million to about 100 billion cells and/or that amount of cells per kilogram of body weight, such as, e.g., 1 million to about 50 billion cells (e.g., about 5 million cells, about 25 million cells, about 500 million cells, about 1 billion cells, about 5 billion cells, about 20 billion cells, about 30 billion cells, about 40 billion cells, or a range defined by any two of the foregoing values), such as about 10 million to about 100 billion cells (e.g., about 20 million cells, about 30 million cells, about 40 million cells, about 60 million cells, about 70 million cells, about 80 million cells, about 90 million cells, about 10 billion cells, about 25 billion cells, about 50 billion cells, about 75 billion cells, about 90 billion cells, or a range defined by any two of the foregoing values), and in some cases about 100 million cells to about 50 billion cells (e.g., about 120 million cells, about 250 million cells, about 350 million cells, about 450 million cells, about 650 million cells, about 800 million cells, about 900 million cells, about 3 billion cells, about 30 billion cells, about 45 billion cells) or any value in between these ranges and/or per kilogram of body weight. Again, dosages may vary depending on attributes particular to the disease or disorder and/or patient and/or other treatments.

(904) In some embodiments, the binding molecules or cells are administered as part of a combination treatment, such as simultaneously with or sequentially with, in any order, another therapeutic intervention, such as another TCR, antibody or engineered cell or receptor or agent, such as a cytotoxic or therapeutic agent.

(905) The cells or antibodies in some embodiments are co-administered with one or more additional therapeutic agents or in connection with another therapeutic intervention, either simultaneously or sequentially in any order. In some contexts, the cells are co-administered with another therapy sufficiently close in time such that the cell populations enhance the effect of one or more additional therapeutic agents, or vice versa. In some embodiments, the cells or antibodies are administered prior to the one or more additional therapeutic agents. In some embodiments, the cells or antibodies are administered after to the one or more additional therapeutic agents.

(906) Once the cells are administered to a mammal (e.g., a human), the biological activity of the engineered cell populations and/or binding molecules in some aspects is measured by any of a number of known methods. Parameters to assess include specific binding of an engineered or natural T cell or other immune cell to antigen, in vivo, e.g., by imaging, or ex vivo, e.g., by ELISA or flow cytometry. In certain embodiments, the ability of the engineered cells to destroy target cells can be measured using any suitable method known in the art, such as cytotoxicity assays described in, for example, Kochenderfer et al., J. Immunotherapy, 32(7): 689-702 (2009), and Herman et al. J. Immunological Methods, 285(1): 25-40 (2004). In certain embodiments, the biological activity of the cells also can be measured by assaying expression and/or secretion of certain cytokines, such as CD 107a, IFN?, IL-2, and TNF. In some aspects the biological activity is measured by assessing clinical outcome, such as reduction in tumor burden or load.

(907) In certain embodiments, engineered cells are modified in any number of ways, such that their therapeutic or prophylactic efficacy is increased. For example, the engineered TCRs or antibody-expressing CARs expressed by the engineered cells in some embodiments are conjugated either directly or indirectly through a linker to a targeting moiety. The practice of conjugating compounds, e.g., the TCR or CAR, to targeting moieties is known in the art. See, for instance, Wadwa et al., J. Drug Targeting 3:111 (1995), and U.S. Pat. No. 5,087,616.

(908) C. Diagnostic and Detection Methods

(909) Also provided are methods involving use of the provided binding molecules, e.g., TCRs or antigen-binding fragments thereof and antibodies and antigen-binding fragments thereof, in detection of HPV 16, e.g., HPV 16 E6 or HPV 16 E7, for example, in diagnostic and/or prognostic methods in association with a HPV 16-expressing disease or condition. The methods in some embodiments include incubating a biological sample with the binding molecule and/or administering the binding molecule to a subject. In certain embodiments, a biological sample includes a cell or tissue, such as tumor or cancer tissue. In certain binding molecule to a region or peptide epitope of HPV 16, e.g., HPV 16 E6 or E7, and detecting whether a complex is formed between the binding molecule and peptide epitope. Such a method may be an in vitro or in vivo method. In one embodiment, an anti-HPV 16 binding molecule is used to select subjects eligible for therapy with an anti-HPV 16 binding molecules or engineered cells comprising such molecules, e.g. where HPV 16, e.g., HPV 16 E6 or E7 is a biomarker for selection of patients.

(910) In some embodiments, a sample, such as a cell, tissue sample, lysate, composition, or other sample derived therefrom is contacted with the binding molecule and binding or formation of a complex between the binding molecule and the sample (e.g., region or epitope of HPV16 in the sample) is determined or detected. When binding in the test sample is demonstrated or detected as compared to a reference cell of the same tissue type, it may indicate the presence of an associated disease or condition. In some embodiments, the sample is from human tissues.

(911) Various methods known in the art for detecting specific binding molecule-antigen binding can be used. Exemplary immunoassays include fluorescence polarization immunoassay (FPIA), fluorescence immunoassay (FIA), enzyme immunoassay (EIA), nephelometric inhibition immunoassay (NIA), enzyme linked immunosorbent assay (ELISA), and radioimmunoassay (RIA). An indicator moiety, or label group, can be attached to the subject binding molecules and may be selected so as to meet the needs of various uses of the method which are often dictated by the availability of assay equipment and compatible immunoassay procedures. Exemplary labels include radionuclides (e.g. .sup.12I, .sup.131I, .sup.35S, .sup.3H, or .sup.32P), enzymes (e.g., alkaline phosphatase, horseradish peroxidase, luciferase, or ?-glactosidase), fluorescent moieties or proteins (e.g., fluorescein, rhodamine, phycoerythrin, GFP, or BFP), or luminescent moieties (e.g., Qdot? nanoparticles supplied by the Quantum Dot Corporation, Palo Alto, Calif.). General techniques to be used in performing the various immunoassays noted above are known to those of ordinary skill in the art.

(912) For purposes of diagnosis, the binding molecules can be labeled with a detectable moiety including but not limited to radioisotopes, fluorescent labels, and various enzyme-substrate labels know in the art. Methods of conjugating labels to binding molecules, e.g., TCRs or antibodies, are known in the art. In some embodiments, the binding molecules need not be labeled, and the presence thereof can be detected using a labeled antibody which binds to the binding molecules.

(913) The provided binding molecules in some embodiments can be employed in any known assay method, such as competitive binding assays, direct and indirect sandwich assays, and immunoprecipitation assays. The binding molecules can also be used for in vivo diagnostic assays, such as in vivo imaging. Generally, the binding molecule is labeled with a radionuclide (such as .sup.111In, .sup.99Tc, .sup.14C, .sup.131I, .sup.125I, or .sup.3H) so that the cells or tissue of interest can be localized in vivo following administration to a subject. The binding molecule may also be used as staining reagent in pathology, e.g., using known techniques.

VII. Articles of Manufacture

(914) Also provided are articles of manufacture containing the provided binding molecules, e.g., TCRs, antibodies, and CARs and/or engineered cells, and/or compositions. The articles of manufacture may include a container and a label or package insert on or associated with the container. Suitable containers include, for example, bottles, vials, syringes, IV solution bags, etc. The containers may be formed from a variety of materials such as glass or plastic.

Alternatively, or additionally, the article of manufacture may further include another or the same container comprising a pharmaceutically-acceptable buffer. It may further include other materials such as other buffers, diluents, filters, needles, and/or syringes.

VIII. Definitions

(915) Unless defined otherwise, all terms of art, notations and other technical and scientific terms or terminology used herein are intended to have the same meaning as is commonly understood by one of ordinary skill in the art to which the claimed subject matter pertains. In some cases, terms with commonly understood meanings are defined herein for clarity and/or for ready reference, and the inclusion of such definitions herein should not necessarily be construed to represent a substantial difference over what is generally understood in the art.

(916) The terms polypeptide and protein are used interchangeably to refer to a polymer of amino acid residues, and are not limited to a minimum length. Polypeptides, including the provided antibodies and antibody chains and other peptides, e.g., linkers, may include amino acid residues including natural and/or non-natural amino acid residues. The terms also include post-expression modifications of the polypeptide, for example, glycosylation, sialylation, acetylation, phosphorylation, and the like. In some aspects, the polypeptides may contain modifications with respect to a native or natural sequence, as long as the protein maintains the desired activity. These modifications may be deliberate, as through site-directed mutagenesis, or may be accidental, such as through mutations of hosts which produce the proteins or errors due to PCR amplification.

(917) An isolated nucleic acid refers to a nucleic acid molecule that has been separated from a component of its natural environment. An isolated nucleic acid includes a nucleic acid molecule contained in cells that ordinarily contain the nucleic acid molecule, but the nucleic acid molecule is present extrachromosomally or at a chromosomal location that is different from its natural chromosomal location.

(918) Isolated nucleic acid encoding a TCR or an antibody refers to one or more nucleic acid molecules encoding TCR alpha or beta chains (or fragments thereof) or antibody heavy and light chains (or fragments thereof), including such nucleic acid molecule(s) in a single vector or separate vectors, and such nucleic acid molecule(s) present at one or more locations in a host cell.

(919) The terms host cell, host cell line, and host cell culture are used interchangeably and refer to cells into which exogenous nucleic acid has been introduced, including the progeny of such cells. Host cells include transformants and transformed cells, which include the primary transformed cell and progeny derived therefrom without regard to the number of passages. Progeny may not be completely identical in nucleic acid content to a parent cell, but may contain mutations. Mutant progeny that have the same function or biological activity as screened or selected for in the originally transformed cell are included herein.

(920) As used herein, percent (%) amino acid sequence identity and percent identity when used with respect to an amino acid sequence (reference polypeptide sequence) is defined as the percentage of amino acid residues in a candidate sequence (e.g., the subject antibody or fragment) that are identical with the amino acid residues in the reference polypeptide sequence, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity, and not considering any conservative substitutions as part of the sequence identity. Alignment for purposes of determining percent amino acid sequence identity can be achieved in various ways that are within the skill in the art, for instance, using publicly available computer software such as BLAST, BLAST-2, ALIGN or Megalign (DNASTAR) software. Those skilled in the art can determine appropriate parameters for aligning sequences, including any algorithms needed to achieve maximal alignment over the full length of the sequences being compared.

(921) An amino acid substitution may include replacement of one amino acid in a polypeptide with another amino acid. Amino acid substitutions may be introduced into a binding molecule, e.g., TCR or antibody, of interest and the products screened for a desired activity, e.g., retained/improved antigen binding, decreased immunogenicity, or improved cytolytic activity.

(922) Amino acids generally can be grouped according to the following common side-chain properties: (1) hydrophobic: Norleucine, Met, Ala, Val, Leu, Ile; (2) neutral hydrophilic: Cys, Ser, Thr, Asn, Gln; (3) acidic: Asp, Glu; (4) basic: His, Lys, Arg; (5) residues that influence chain orientation: Gly, Pro; (6) aromatic: Trp, Tyr, Phe.

(923) In some embodiments, conservative substitutions can involve the exchange of a member of one of these classes for another member of the same class. In some embodiments, non-conservative amino acid substitutions can involve exchanging a member of one of these classes for another class.

(924) The term vector, as used herein, refers to a nucleic acid molecule capable of propagating another nucleic acid to which it is linked. The term includes the vector as a self-replicating nucleic acid structure as well as the vector incorporated into the genome of a host cell into which it has been introduced. Certain vectors are capable of directing the expression of nucleic acids to which they are operatively linked. Such vectors are referred to herein as expression vectors.

(925) The term package insert is used to refer to instructions customarily included in commercial packages of therapeutic products, that contain information about the indications, usage, dosage, administration, combination therapy, contraindications and/or warnings concerning the use of such therapeutic products.

(926) As used herein, the singular forms a, an, and the include plural referents unless the context clearly dictates otherwise. For example, a or an means at least one or one or more. It is understood that aspects and variations described herein include consisting and/or consisting essentially of aspects and variations.

(927) Throughout this disclosure, various aspects of the claimed subject matter are presented in a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the claimed subject matter. Accordingly, the description of a range should be considered to have specifically disclosed all the possible sub-ranges as well as individual numerical values within that range. For example, where a range of values is provided, it is understood that each intervening value, between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the claimed subject matter. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges, and are also encompassed within the claimed subject matter, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the claimed subject matter. This applies regardless of the breadth of the range.

(928) The term about as used herein refers to the usual error range for the respective value readily known to the skilled person in this technical field. Reference to about a value or parameter herein includes (and describes) embodiments that are directed to that value or parameter per se. For example, description referring to about X includes description of X.

(929) As used herein, a composition refers to any mixture of two or more products, substances, or compounds, including cells. It may be a solution, a suspension, liquid, powder, a paste, aqueous, non-aqueous or any combination thereof.

(930) As used herein, a statement that a cell or population of cells is positive for a particular marker refers to the detectable presence on or in the cell of a particular marker, typically a surface marker. When referring to a surface marker, the term refers to the presence of surface expression as detected by flow cytometry, for example, by staining with an antibody that specifically binds to the marker and detecting said antibody, wherein the staining is detectable by flow cytometry at a level substantially above the staining detected carrying out the same procedure with an isotype-matched control under otherwise identical conditions and/or at a level substantially similar to that for cell known to be positive for the marker, and/or at a level substantially higher than that for a cell known to be negative for the marker.

(931) As used herein, a statement that a cell or population of cells is negative for a particular marker refers to the absence of substantial detectable presence on or in the cell of a particular marker, typically a surface marker. When referring to a surface marker, the term refers to the absence of surface expression as detected by flow cytometry, for example, by staining with an antibody that specifically binds to the marker and detecting said antibody, wherein the staining is not detected by flow cytometry at a level substantially above the staining detected carrying out the same procedure with an isotype-matched control under otherwise identical conditions, and/or at a level substantially lower than that for cell known to be positive for the marker, and/or at a level substantially similar as compared to that for a cell known to be negative for the marker.

(932) All publications, including patent documents, scientific articles and databases, referred to in this application are incorporated by reference in their entirety for all purposes to the same extent as if each individual publication were individually incorporated by reference. If a definition set forth herein is contrary to or otherwise inconsistent with a definition set forth in the patents, applications, published applications and other publications that are herein incorporated by reference, the definition set forth herein prevails over the definition that is incorporated herein by reference.

(933) The section headings used herein are for organizational purposes only and are not to be construed as limiting the subject matter described.

X. EXAMPLES

(937) The following examples are included for illustrative purposes only and are not intended to limit the scope of the invention.

Example 1: Screening and Selection of HPV-16 E6 and E7 Epitope-Specific T Cell Receptors from Normal Donors

(938) An exemplary autologous screening process using autologous dendritic and T cells, generally as described by Ho et al., J. Immunol. Methods, 310:1-2, 40-52, with indicated modifications, was performed to generate antigen-specific T cells that specifically bound to peptide epitopes of human papillomavirus 16 (HPV16) E6 and E7 proteins presented on MHC-I molecules. Clonal T cell lines were generated and their TCR sequences cloned by this method were cloned.

(939) A. Generation and Cloning of Human HPV-Specific T Cells and TCRs

(940) Briefly, dendritic cells were derived from adherent fractions of peripheral blood mononuclear cell (PBMC) samples obtained from normal human HLA-A02:01 donors, by culturing over two days in the presence of GM-CSF and IL-4, followed by incubation beginning at day 3 in the presence of pro-inflammatory cytokines to produce mature dendritic cells. On Day 4, the resulting mature dendritic cells were harvested, washed and pulsed with HPV-16 E6- or E7-derived peptides, such as some of those shown in Table 23, including peptide epitopes E6 (29-38), E7 (11-19), and E7 (86-93).

(941) TABLE-US-00035 TABLE 23 HPV-16 Epitopes Epitope Epitope SEQ ID Description Name NO. KLPQLCTEL E6(18-26) 232 TIHDIILECV E6(29-38) 233 FAFRDLCIV E6(52-60) 234 TLGIVCPI E7(86-93) 235 YMLDLQPET E7(11-19) 236 GTLGIVCPI E7(85-93) 237 LLMGTLGIV E7(82-90) 238 TLHEYMLDL E7(7-15) 239

(942) On Day 5, autologous CD8+ T cells from normal human donors were incubated with the peptide-pulsed dendritic cells.

(943) On Day 8, IFN? in the cultures was measured as an indicator for cultures containing antigen-specific T cells. Cells from reactive co-cultures were selected and re-stimulated two or three times with peptide-pulsed dendritic cells to enrich for specific T cells. Following the repeated stimulations, populations of cells staining positive for peptide-loaded autologous MHC tetramers were identified by flow cytometry. Clonal lines were generated by cell sorting and/or limiting dilution cloning essentially as described by Ho et al. 2006.

(944) Clones were cultured with peptide-pulsed T2 cells (cells deficient in transporter associated with antigen transport (TAP) but expressing MHC-I and thus able to present peptides loaded onto the cells), pulsed with the relevant peptide, e.g. E6 (29-38), E7 (11-19) or E7 (86-93). Level of IFN? in the cultures, as compared to those resulting from co-culture with cells loaded with a non-HPV-derived (negative control) peptide, was measured as an indicator of T cell specificity for the peptide-MHC and functional activity. Flow cytometry-based staining was used to assess the ability of the clonal cell lines to bind, in a peptide-specific manner, to labeled peptide-MHC (HLA-A02:01) tetramers (either HLA-A2/E6 (29-38), HLA-A2/E7 (11-19) or HLA-A2/E7 (86-93)); tetramers containing an irrelevant peptide served as a negative control).

(945) Table 24 lists sequence identifiers corresponding to TCR alpha and beta chains expressed by clonal T cell lines generated via this process.

(946) The ability of clonal lines to lyse target cells in an antigen-specific manner was assessed using peptide-pulsed T2 cells and/or cells of an antigen-expressing cancer cell line.

(947) In an exemplary assay, monoclonal cell lines expressing the TCRs were incubated with the CaSki target cells (ATCC No. CRL-1550, containing approximately 600 copies of integrated HPV16) at various effector:target (E:T) ratios. Lytic activity was assessed by measuring caspase in the target cells and assessing the percentage of such cells that were positive to caspase at various time-points following initiation of incubation with the T cells, over 50 hours. Negative controls included incubation of T cells with SiHa cells (ATCC No. HTB-35, essentially negative for the endogenous target antigen, having no more than approximately one or two copies of integrated HPV16 genome) and Caski cells not incubated with T cell clones. The results for two exemplary clonal T cell lines are shown in FIG. 1. As shown, the monoclonal T cell lines were observed to exhibit lytic activity against cells presenting the subject HPV16-derived peptide in the context of HLA-A02:01. A number of CD8+ clones were generated and confirmed to exhibit antigen-specific binding and functionality by this process.

(948) The ability of T cells of clonal lines to specifically bind to peptide epitopes independently of the CD8 co-receptor was assessed using a mutant MHC class I tetramer containing a D227K mutation in its CD8 binding site, rendering it unable to engage the CD8 co-receptor on T cells. See Kerry et al. J Immunol (2003) 171:4493-4503; Kerry et al. Immunology (2005) 114: 44-52. Table 24 lists exemplary TCRs expressed by exemplary clonal cell lines generated by this method. Each of these cell lines was observed in this study to bind the indicated peptide-MHC complex in an antigen-specific manner, as indicated by tetramer staining in comparison to control. Additionally, the indicated clonal lines were observed to specifically bind the relevant peptide in the context of the mutant (non-CD8 interacting) tetramers, indicating the ability of the TCRs expressed by these clonal lines to specifically bind to cognate antigen independently of CD8.

(949) B. Cloning of TCRs Expressed by Clonal Cell Lines

(950) Polynucleotides having sequences encoding the polypeptide chains of TCRs from clonal lines generated as described above were amplified from T cell lines and sequenced using 5 rapid amplification of cDNA ends (RACE). Table 24 provides the sequence identifier (SEQ ID NO) for the alpha and beta chain nucleotide and amino acid sequences, respectively, for a plurality of TCRs generated by this process. Table 24 also lists the SEQ ID NO corresponding to an exemplary full-length encoded amino acid sequence containing the beta and alpha chain sequences of each respective TCR, separated by a ribosome-skip P2A sequence (P2A linker set forth in SEQ ID NO: 204, which may be encoded by a sequence of nucleotides set forth in any of SEQ ID NOs: 4, 5, 6, 207-210) (designated beta-P2A-alpha). A nucleotide sequence encoding such a full-length sequence for each of a number of TCRs was inserted into a vector for transfer into a host cell, such as a primary human cell, e.g., a T cell, as described below. Following translation of the nucleotide sequence and self-cleavage of the P2A sequence separating the TCR chains, the recombinant alpha and beta chain of the TCR were exogenously expressed in host cells, such as a primary T cell, for example a primary human T cell. The Table 24 also lists the specific Valpha and Vbeta usage for each cloned TCR.

(952) C. Codon Optimization, Modification and Lentiviral Expression

(953) Nucleotide sequences encoding TCRs generated as described above were modified by codon optimization and/or by mutation(s) to promote the formation of a non-native disulfide bond in the interface between the TCR constant domains to increase pairing and stability of the TCR. The non-native disulfide bond was promoted by modifying the TCR chains at residue 48 in the C? region from Thr to Cys and residue 57 of the C? region from Ser to Cys (see Kuball et al. (2007) Blood, 109:2331-2338). The corresponding SEQ ID NO for the resulting modified nucleotide sequences and corresponding encoded amino acid sequences for the modified version of each TCR are shown in Table 25.

(954) For individual TCRs modified as described above, constructs were generated that contained the modified nucleotide sequences encoding the beta chain and alpha chain, respectively, of the cloned TCRs, separated by a sequence encoding a P2A polypeptide were generated and inserted into a lentiviral vector, which were used to transduce T cell lines and primary human T cells using standard methods, to express the encoded TCR chains.

Example 2: Expression and Antigen-Binding of Exemplary TCRs in Jurkat Cells

(956) Exemplary E6-specific and E7-specific T cell receptors (TCRs), generated as described above, were assessed for surface expression on T cells and antigen-specific binding with or without CD8 interaction. Specifically, cells derived from the Jurkat human T cell line that did not express the endogenous TCR on their surfaces (CD4+ Jurkat-derived cells), with or without exogenously expressed CD8, referred to in FIG. 2A-2L, FIG. 3A-3D AND FIG. 4A-4B, as CD8+ and CD4+, respectively, were engineered to express the modified version of the TCRs. For each TCR assessed in this process, the Jurkat-derived cells were transduced with a lentiviral vector particle generated as described above encoding the particular modified version of the TCR. Cells (those containing or not containing exogenous CD8) not transduced with a TCR were used as controls. At day 6 post-transduction with the sequence encoding each TCR, TCR expression and functional activity were assessed by flow cytometry, following staining with labeled tetramers complexed with the respective E6- or E7-peptide (either HLA-A2/E6 (29-38), HLA-A2/E7 (11-19) or HLA-A2/E7 (86-93) tetramer). A reference TCR capable of binding to HLA-A2/E6 (29-38) also was assessed in this study (described in International PCT Publication No. and WO 2015/009606). The reference TCR contains a mouse constant region.

(957) Exemplary results are shown in FIG. 2A-2L (E6(29-38)-loaded tetramer binding), FIG. 3A-3D (E7 (11-19)-loaded tetramer binding) and FIG. 4A-4B (E7(86-93)-loaded tetramer binding). The percentage of cells in the indicated quadrants in flow cytometry plots shown in FIGS. 2A-2L, 3A-3D and 4A-4B are also summarized below in Table 26A (FIG. 2A-2F), Table 26B (FIG. 2G-2L), Table 26C (FIGS. 3A-3D) and Table 26D (FIG. 4A-4B).

(962) As shown, TCRs generated by these methods were cloned and observed to be expressed on the surface of T cells and to bind HPV peptide in the context of MHC tetramers, in some cases independently of CD8 co-receptor.

Example 3: Functional Assessment of Cells Transduced with HPV-16 E6 and E7 Epitope-Specific T Cell Receptors

(963) Primary CD8+ human T cells were transduced with a lentiviral vector particle generated as described above encoding chains of modified versions of TCRs specific for E6(29-38) in the context of HLA:A2:01, including exemplary modified versions of TCRs TCR 5, TCR 4, TCR 3, TCR 8, TCR 9, TCR 10 and TCR7. Such transduced T cells were assessed for functional activity, including the ability to generate cytokines and exhibit lytic activity in response to cells expressing the peptide: MHC. An exemplary E7(11-19)-specific TCR was used as a negative control in these studies.

(964) A. Cytokine Production

(965) To assess the production of cytokines in response to antigen, the cells were incubated for 4 hours at a 10:1 E:T ratio with T2 cells that had been pulsed overnight with 10)(M of E6(29-38) peptide or, as a control, 10)(M of E7(11-19) peptide. As a positive control, cytokine activity also was assessed in cultures of transduced T cells stimulated with either phorbol myristate acetate (PMA) and Brefeldin A (BFA) or with BFA alone. Intracellular IFN? was measured in the cultured cells by flow cytometry. The percent of CD8 and intracellular IFN? positive (% CD8+/IC IFN?+) cells was determined by flow cytometry.

(966) The results are shown in Table 27. These results confirmed the ability of primary human T cells expressing E6(29-38)-specific TCRs generated by these methods to produce cytokine in response to target cells in an antigen-specific manner.

(968) B. Lytic Activity

(969) Lytic activity of the transduced primary human T cells against cells expressing HPV16 was assessed by incubating CaSki cells (in the presence or absence of IFN?) at a 10:1 E:T ratio. Samples in which SiHa cells were used as the target cells at the same E:T ratio served as a negative control. Lytic activity also was assessed against T2 cells pulsed with peptide E6(29-38). The ability of the T cells to antigen-specifically cause lytic activity was assessed by measuring active-caspase in the target cells 4 hours post co-culture.

Example 4: Screening and Selection of HPV-16 E6 and E7 Epitope-Specific T Cell Receptors from Normal Donors

(970) A screening process using autologous dendritic and T cells was performed to generate antigen-specific T cell receptors (TCRs) that specifically bound to human papillomavirus 16 (HPV16) E6(29-38) or E7(11-19) peptide presented on MHC-I molecules and survived and/or were enriched over time, following multiple rounds of antigen-stimulation. Clonal T cell lines were generated and the sequences of individual paired TCR alpha and beta chains and abundance thereof in various populations were determined on a single-cell basis, using high-throughput paired TCR sequencing.

(971) A. Generation and Cloning of Human HPV-Specific T Cells and TCRs

(972) Briefly, peptide-pulsed antigen-presenting cells were generated from PBMCs from human donors substantially as described in Example 1. Specifically, peptide-pulsed HLA:A02:01APCs were generated with HPV 16 E6(29-38) peptide (TIHDIILECV; SEQ ID NO:233) or E7(11-19) peptide (YMLDLQPET; SEQ ID NO:236). Autologous CD8+ T cells from normal human donors were incubated over multiple rounds with the peptide-pulsed cells, and selections were carried out based on binding to peptide-loaded autologous MHC tetramers. Generally, cells were subjected to a total of three rounds of stimulation, in the presence of peptide-pulsed cells (with a peptide concentration of 1000 ng/mL maintained over the three rounds). Following the second and third rounds of stimulation, cells were sorted by flow cytometry into populations positive and negative, respectively, for binding to peptide-MHC tetramers containing the appropriate tetramer. Cells of the tetramer-positive and negative populations following each of the second and third rounds were subjected to single-cell TCR sequencing, to assess the presence and frequency of individual TCRs in the different populations, and the persistence of TCR clones over multiple rounds of antigen stimulation.

(973) B. Determination of TCR Sequences and Assessment of TCRs

(974) Cell populations from the positive and negative fractions (i.e., sorted by flow cytometry based on positive and negative staining, respectively, for binding to the E6(29-38) peptide-loaded, or E7(11-19) peptide-loaded, MHC tetramers, as determined by flow cytometry) following rounds 2 and 3 of stimulation were subject to high-throughput single-cell sequencing for TCR alpha and beta chain pairs. High throughput single cell TCR sequencing was performed as generally described in published PCT patent applications, publication numbers WO2012/048340, WO2012/048341 and WO2016/044227. The sequencing methods employed single-cell droplets and sample and molecular barcodes, to identify individual pairs of TCR alpha and beta chain sequences at a single-cell level, for each of a large number (e.g., millions) of single cells present in a single starting composition, and to assess abundance of each TCR pair in various populations assessed. The ability to identify and quantify TCR pairs at a single-cell level permitted the assessment of the frequency of each of various TCR pairs in each of the individual positive and negative fractions, and to assess enrichment and persistence of TCRs over multiple rounds of antigen stimulation. TCR pairs identified in this assay were selected based on their presence in the peptide-binding fractions following rounds 2 and 3, higher abundance in positive versus negative fractions in each of these rounds, and enrichment over time following multiple rounds of exposure to antigen.

(975) Tables 28 and 29 list exemplary E6(29-38)- and E7(11-19)-specific TCRs isolated according to this method, respectively, and the sequence identifiers (SEQ ID NO:) for the alpha and beta chain nucleotide and amino acid sequences for each TCR. Tables 28 and 29 also list the sequence identifier (SEQ ID NO) corresponding to an exemplary full-length encoded amino acid sequence containing the beta and alpha chain sequences of each respective TCR, separated by a sequence encoding a ribosome-skip P2A sequence (P2A linker set forth in SEQ ID NO: 204) (designated beta-P2A-alpha). A nucleotide sequence encoding such a full-length sequence for each of a number of TCRs was inserted into a vector for transfer into a host cell, such as a primary human cell, e.g., a T cell, as described below. Following translation of the nucleotide sequence and self-cleavage of the P2A sequence separating the TCR chains, the recombinant alpha and beta chain of the TCR were exogenously expressed in host cells.

(978) C. Codon Optimization and Modification

(979) Nucleotide sequences encoding TCRs generated as described above were modified by codon optimization and/or by mutation(s) to promote the formation of a non-native disulfide bond in the interface between the TCR constant domains to increase pairing and stability of the TCR. The non-native disulfide bond was promoted by modifying the TCR chains at residue 48 in the C? region from Thr to Cys and residue 57 of the C? region from Ser to Cys (see Kuball et al. (2007) Blood, 109:2331-2338). The corresponding SEQ ID NO for the resulting modified nucleotide sequences and corresponding encoded amino acid sequences for the modified version of each TCR are shown in Table 30 (E6(29-38)-specific TCR) and Table 31 (E7(11-19)-specific TCRs).

(980) For individual TCRs modified as described above, constructs were generated that contained the modified nucleotide sequences encoding the beta chain and alpha chain, respectively, of the cloned TCRs, separated by a sequence encoding a P2A polypeptide and inserted into a vector, e.g. lentiviral vector, which were used for expressing the TCR chain in T cell lines and primary human T cells using standard methods.

Example 5: Expression and Antigen-Binding of Exemplary E6- and E7-Specific TCRs

(983) Exemplary E6- and E7-specific T cell receptors (TCRs), identified as described in Example 4 above that were codon-optimized and cysteine-modified, were expressed in T cells and assessed for surface expression and antigen-specific binding, with or without CD8 interaction substantially as described in Example 2 above. Specifically, CD4+ Jurkat-derived cells that did not express endogenous TCR on their surfaces, that either had or had not been modified by introduction of exogenous CD8 (modification resulting in CD4+/CD8+ cells), were mixed in a 1:1 mixture for transfection with plasmid DNA encoding the TCRs, to assess CD8-independent binding activity of the TCRs. For transfection, the CD4+ and CD4+/CD8+ cell mixtures were transiently transfected with TCR-encoding plasmids and 48 hours after transfection, cells were assessed by flow cytometry for (1) binding of the target peptide in the context of an MHC molecule (HLA:A02:01) by staining with an E6(29-38) peptide- or an E7(11-19) peptide-MHC tetramer reagent, and/or (2) CD8+ independent binding of the target by co-staining the tetramer-labeled cells with an anti-CD8 antibody. Cells that had been mock transfected (mock) and cells expressing a reference TCR capable of binding to HLA-A2/E6(29-38) also were assessed in this study.

(984) Exemplary results are shown in FIGS. 5A-5F (E6(29-38)-loaded tetramer binding) and FIGS. 6A-6F (E7 (11-19)-loaded tetramer binding). The percentage of cells in the indicated quadrants in flow cytometry plots shown in FIGS. 5A-51I and 6A-61I are also summarized below in Table 32 (flow cytometry plots showing E6(29) tetramer and CD8+ staining results for CD8+ cells from TCR-transfected compositions; FIGS. 5A-5C), Table 33 (flow cytometry plots showing results for E6(29)-specific TCR-transfected cell compositions; FIGS. 5D-5F) and Table 34 (flow cytometry plots showing results for E7(11)-specific TCRs; FIG. 6A-6F). Specifically, FIGS. 5A-5C depict flow cytometry plots for tetramer and CD8 staining in CD8+ populations; FIGS. 5D-5F and 6A-6F depict plots reflecting staining of CD8+ and CD8-populations.

(988) As shown, the exemplary assessed TCRs were expressed on the surface of T cells and recognized HPV peptide in the context of MHC tetramers. In some cases, the binding was independent of CD8 co-receptor, as indicated by tetramer.sup.+ cells in the CD8.sup.? population in FIGS. 5D-5F (percentages listed in Table 33) and FIGS. 6A-6F (percentages listed in Table 34).

(989) The results of an additional study assessing the CD8-independent tetramer binding of cells expressing exemplary recombinant E7-specific TCRs, TCR37 and TCR49 that were codon-optimized and cysteine-modified, are shown in FIG. 6G. As shown, cells expressing exemplary recombinant TCR, TCR49, were observed to exhibit CD8-dependent tetramer binding (left panel), and cells expressing exemplary recombinant TCR, TCR37, were observed to exhibit some CD8-independent tetramer binding. The results were consistent with a finding that certain MHC Class I-restricted recombinant TCRs can function in CD4+ cells, showing CD8-independent tetramer binding.

Example 6: Expression and Assessment of Exemplary Recombinant T Cell Receptors (TCRs) in Primary T Cells

(990) Expression and function of exemplary recombinant E7-specific TCRs in primary human T cells was assessed.

(991) Primary human CD4+ and CD8+ T cells were transduced with lentiviral preparations encoding TCR 16, specific for HPV 16 E6(29-38); and TCR 49, TCR 53 and TCR 37, each specific for HPV 16 E7(11-19) (described above in Example 4 above, and that were codon optimized and cysteine-modified). Approximately 5?10.sup.6 primary human CD4+ and CD8+ T cells were isolated by immunoaffinity-based selection from human peripheral blood mononuclear cells (PBMCs) obtained from healthy donors. The cells were stimulated for 24 hours by culturing with an anti-CD3/anti-CD28 reagent in media containing human serum and cytokines, at 37? C. prior to lentiviral transduction. Stimulated cells were transduced with a lentiviral preparation encoding TCR 16, TCR 49, TCR 53 or TCR 37, or a mock transduction control (cells treated under the same conditions used for lentiviral transduction but without addition of lentivirus). The lentiviral constructs also contained sequences encoding EGFRt as a surrogate marker for transduction and expression, separated from the recombinant TCR encoding sequences by a sequence encoding a T2A ribosome skip sequence. Following transduction, the cells were cultured in media containing human serum and cytokines. On day 13 after transduction, the cells were assessed by flow cytometry for staining with an anti-CD3 antibody, an anti-CD8 antibody, and a HPV 16 E6(29-38)- or HPV16 E7(11-19)-peptide-MHC tetramer complex. Interferon-gamma (IFN?) production was assessed following incubation of recombinant TCR-expressing cells with a squamous cell carcinoma cell line UPCI:SCC152 (ATCC? CRL-3240?), an antigen-specific target cell line which is HPV+, at an E:T ratio of 7.5:1 or 3.25:1 for TCR 16-expressing cells, and E:T ratio of 2.5:1 for TCR 49-, TCR 53- or TCR 37-expressing cells.

(992) The results showed binding of the respective peptide-MHC tetramer complex specific for each TCR. TCR 16-expressing cells produced IFN? at levels above background at both E:T ratios tested. CD8+ cells expressing TCR 49, TCR 53 or TCR 37 produced IFN? at levels above background, and CD4+ cells expressing TCR 53 and TCR 37 produced IFN? at levels above background, consistent with CD8-independent function of these TCRs in primary T cells. The results are consistent with expression, cell surface expression and antigen-specific function of the recombinant TCRs in primary T cells.

Example 7: Assessment of Primary T Cells with Endogenous TCR Gene Knock-Out

(993) Primary human CD4+ and CD8+ T cells were isolated and engineered to introduce a genetic disruption to knockout (KO) the endogenous gene loci that encode the T cell receptor alpha (TCR?) and beta (TCR?) chains or both by CRISPR/Cas9-mediated gene editing. Primary CD4+ and CD8+ T cells from two healthy human donors were isolated by immunoaffinity-based selection from human peripheral blood mononuclear cells (PBMCs) obtained from healthy donors. The isolated CD4+ and CD8+ cells were stimulated for 72 hours at 37? C. by culturing with an anti-CD3/anti-CD28 reagent at a 1:1 bead:cell ratio in media containing human serum, IL-2, IL-7 and IL-15.

(994) For introducing genetic disruption at the TCR loci, the anti-CD3/anti-CD28 reagent was removed, and the cells were electroporated with either 2 ?M ribonucleoprotein (RNP) complexes containing Streptococcus pyogenes Cas9 and a guide RNA (gRNA) targeting TCR ? constant regions gene (TRAC), or 2 ?M RNP complexes containing S. pyogenes Cas9 and a gRNA targeting the TCR ? constant region genes (TRBC). For targeting both TRAC and TRBC, a mixture of the RNP complexes were electroporated. Specifically, the TRAC locus was targeted for genetic disruption with a gRNA with the targeting domain sequence GAGAAUCAAAAUCGGUGAAU (SEQ ID NO:1048; target site sequence for TRAC set forth in SEQ ID NO:1182), which targets a genetic disruption within exon 1 of the endogenous TCR ? constant region (TRAC) gene. The TRBC loci were targeted for genetic disruption with a consensus target site sequence common to exon 1 of both TCR ? constant regions 1 and 2, with the targeting domain sequence GGCCUCGGCGCUGACGAUCU (SEQ ID NO:1053; target site sequence for TRBC set forth in SEQ ID NO:1054). As a control, cells were treated under the same conditions used for electroporation but without addition of an RNP (mock).

(995) Knockout efficiency was measured by evaluating CD3 expression using flow cytometry 5 days after transfection, and the percentage of CD3-population was determined. As shown in FIGS. 7A and 7B, cells electroporated with RNPs targeting the endogenous TCR genes to disrupt the endogenous gene loci that encode the T cell receptor alpha (TCR?) constant and beta (TCR?) constant chains or both, resulted in cells that did not express CD3, indicating that they were knocked out for the expression of the endogenous TCR. In this study, approximately 80% of cells were knocked out for the endogenous TCR as determined by CD3 expression when either TRAC or TRBC were targeted individually, with a greater number of cells knocked out for the endogenous TCR when both TRAC and TRBC were targeted.

Example 8: Expression of Exemplary Recombinant T Cell Receptors (TCRs) in Primary T Cells with Endogenous TCR Gene Knock-Out

(996) Primary human T cells were knocked out for the endogenous T cell receptor-encoding genes using CRISPR/Cas9 mediated gene editing, and transduced with lentiviral vector particles encoding exemplary recombinant E6- or E7-specific TCRs.

(997) A. Knock-Out of Endogenous TCR Genes and Expression of Recombinant TCR in Primary T Cells

(998) Approximately 5?10.sup.6 primary human CD4+ and CD8+ T cells were isolated by immunoaffinity-based selection from human peripheral blood mononuclear cells (PBMCs) obtained from healthy donors. The cells were stimulated for 24 hours by culturing with an anti-CD3/anti-CD28 reagent in media containing human serum, interleukin-2 (IL-2), IL-7 and IL-15 at 37? C. prior to lentiviral transduction. Stimulated cells were transduced with a lentiviral preparation encoding TCR 16 (codon-optimized and cysteine-modified), specific for HPV 16 E6(29-38); TCR 31 (codon-optimized and cysteine-modified), specific for HPV 16 E7(11-19), described in Example 4 above; or a mock transduction control (cells treated under the same conditions used for lentiviral transduction but without addition of lentivirus. The lentiviral constructs also contained sequences encoding a truncated receptor as a surrogate marker for transduction and expression, separated from the recombinant TCR-encoding sequences by a sequence encoding a T2A ribosome skip sequence. Following transduction, the cells were cultured for 36-48 hours in media containing human serum and IL-2, IL-7 and IL-15.

(999) To knock out the endogenous TCR genes, cells were electroporated with a mixture of ribonucleoprotein (RNP) complexes containing a guide RNA (gRNA) designed to target a target site within exon 1 of the TCR ? constant regions gene (gRNA targeting domain sequence for TRAC set forth in SEQ ID NO:1048; target site sequence for TRAC set forth in SEQ ID NO:1182) and RNP complexes containing a gRNA designed to target a consensus target site sequence common to exon 1 of both TCR ? constant regions 1 and 2 (gRNA targeting domain sequence for TRBC set forth in SEQ ID NO:1053; target site sequence for TRBC set forth in SEQ ID NO:1054) and Streptococcus pyogenes Cas9 protein, for CRISPR/Cas9 mediated gene editing of the TRAC and TRBC loci (endo. TCR KO).

(1000) As a control, cells were treated under the same conditions used for electroporation but without addition of an RNP (endo. TCR WT). The cells were subsequently cultured in culture media containing cytokines. Three days after electroporation with RNP, transduced cells were enriched by selection with an antibody directed against the surrogate marker, and cultured for 8 additional days.

(1001) On day 13 after transduction (day 11 after electroporation), the cells were assessed by flow cytometry for staining with an anti-CD3 antibody, an anti-CD8 antibody, and a labeled MHC tetramer complexed with the antigen recognized by the recombinant TCR (HPV16 E6 or E7 peptide). Cytokine production was monitored following incubation of recombinant TCR-expressing cells with a squamous cell carcinoma cell line UPCI:SCC152 (ATCC? CRL-3240?), an antigen-specific target cell line that are HPV+, at an E:T ratio of 7.5:1, 3.25:1 or 0:1 for 48 hours. Secretion of interferon-gamma (IFN?), IL-2 and tumor necrosis factor alpha (TNF?) was determined by ELISA.

(1002) B. Results

(1003) The knock-out efficiency of the endogenous TCR was assessed by determining the percentage of CD3-population. As shown in FIG. 8A, more than 98% of cells electroporated with RNPs targeting the endogenous TCR genes (endo. TCR KO) did not express CD3, indicating that they were knocked out for the expression of the endogenous TCR. In comparison, more than 98% of the control cells (endo. TCR WT) expressed CD3. The results showed that nearly all of the population of cells was knocked out for the endogenous TCR-encoding genes.

(1004) Recombinant TCR expression was compared in cells with or without knock-out of the endogenous TCR genes. As shown in FIG. 8B, in cells transduced to express TCR 16, the percentage of cells that expressed the TCR (as assessed by the surrogate marker) and bound the peptide-MHC tetramer was increased in the endogenous TCR knock-out cells (endo. TCR KO), compared to control cells (endo. TCR WT) transduced to express TCR16. The results are consistent with a finding that knocking out the endogenous TCR in primary T cells results in improved expression of the recombinant TCR.

(1005) Following incubation with the antigen-specific target cell line, cells expressing recombinant TCRs and knocked out for the endogenous TCR genes (endo. TCR KO) produced more IFN? compared to control cells (endo. TCR WT) expressing the same TCR and the mock transduction control (FIG. 8C). Similar results were observed for IL-2 and TNF? production.

Example 9: Assessment of Expression and Function of Exemplary Recombinant T Cell Receptors (TCRs) in Primary T Cells with or without Endogenous TCR Gene Knock-Out

(1006) Expression and function of exemplary recombinant E7-specific TCRs was assessed in primary human T cells with or without knock-out of the endogenous TCR genes or in which the recombinant E7-specific TCRs were expressed as chimeric TCRs with a mouse constant region.

(1007) Primary human CD4+ and CD8+ T cells were transduced with lentiviral preparations encoding TCR 49, TCR 53 and TCR 37, each specific for HPV 16 E7(11-19) (codon optimized and cysteine-modified, described above in Example 4 above), and a surrogate marker, using methods substantially as described in Example 6. As an alternative approach, primary human CD4+ and CD8+ T cells were transduced with lentiviral preparations encoding each TCR where the C? and the C? of the recombinant TCR were replaced by constant regions from a mouse TCR (mouse constant; mouse Ca sequence set forth in SEQ ID NO:1012; mouse C? sequence set forth in SEQ ID NO:1013). As a control, cells were treated under the same conditions used for lentiviral transduction but without addition of lentivirus (mock transduction).

(1008) Cells transduced with TCR 49, TCR 53 or TCR 37 (containing the human constant region) were electroporated with TRAC- and TRBC-targeting CRISPR/Cas9 RNPs to knock out the endogenous TCR genes (endo. TCR KO) substantially as described in Example 8, or were treated under the same conditions used for electroporation but without addition of an RNP (endo. TCR WT). The other transduced cell conditions also were treated under the same conditions for electroporation but without addition of an RNP. The cells were enriched and cultured, generally as described in Example 8A above.

(1009) On day 13 after transduction (day 11 after electroporation), the cells were assessed by flow cytometry for staining with an anti-CD3 antibody, an anti-CD8 antibody, and a HPV16 E7(11-19) peptide-MHC tetramer complex. Interferon-gamma production was assessed following incubation of recombinant TCR-expressing cells with the antigen-specific UPCI:SCC152 target cells at an E:T ratio of 2.5:1. Cytolytic activity was assessed by incubating CD4+ or CD8+ cells expressing each of the recombinant TCRs with antigen-specific UPCI:SCC152 target cells (stably expressing NucLight Red), and assessing integrated fluorescence intensity over time using an automated microscope.

(1010) Results

(1011) As shown in FIG. 9A (TCR 49), FIG. 9D (TCR 53) and FIG. 9G (TCR 37), expression of the TCRs, as assessed by E7(11-19) tetramer binding, was greater in cells with knock-out of the endogenous TCR genes (endo. TCR KO), compared to in cells that retained the endogenous TCR genes (endo. TCR WT). Increased expression of the recombinant TCRs in primary human T cells also was achieved by introduction of the TCR as a chimeric TCR containing a mouse constant region. In some cases, observed CD8-independent tetramer binding also was increased in cells in which the TCR was expressed with knock-out of the endogenous TCR or by expression as a chimeric TCR containing mouse constant region.

(1012) Cytolytic activity, as monitored by decreased NucRed light signal, of TCR-expressing cells was observed following incubation with antigen-specific target cells as shown in FIG. 9B (TCR 49), 9E (TCR 53), 911 (TCR 37) and 9J (TCR 37). For each TCR, the degree of cytolytic activity was generally consistent with the observed level of expression of the TCR among the various assessed TCR-expressing cells. In some cases, CD4+ cytolytic activity was observed consistent with CD8-independent activity of the TCR.

(1013) As shown in FIG. 9C (TCR 49), 9F (TCR 53), 91 (TCR 37) and 9J (TCR 37), interferon-gamma production by TCR-expressing cells following incubation with antigen-specific target cells also was increased in cells with knock-out of the endogenous TCR genes or in cells in which the TCR was expressed as a chimeric TCR with mouse constant regions. In some cases, increased expression of interferon-gamma was observed in TCR-expressing CD4+ cells consistent with CD8-independent activity of the TCR.

Example 10: Evaluation of Expression, Peptide Sensitivity and Function of Exemplary Recombinant T Cell Receptors (TCRs) in Primary T Cells Eliminated for Endogenous TCR by CRISPR/Cas9-Mediated Gene Editing of TRAC Locus

(1014) Primary human CD4+ and CD8+ T cells were transduced with lentiviral preparations encoding various exemplary TCRs specific for HPV 16 E7(11-19) (codon optimized and cysteine-modified, as described in Example 4). As a control, cells were treated under the same conditions used for lentiviral transduction but without addition of lentivirus (mock). Cells transduced with TCRs were electroporated with TRAC-targeting CRISPR/Cas9 RNPs (containing gRNA targeting domain sequence for TRAC set forth in SEQ ID NO:1048) to knock out the endogenous TCR genes (endo. TCR KO), or were treated under the same conditions used for electroporation but without addition of an RNP (endo. TCR+). The other transduced cell conditions also were treated under the same conditions for electroporation but without addition of an RNP. The cells were enriched and cultured substantially as described in Example 8.

(1015) On 6 days after transduction (4 days after electroporation), the cells were assessed by flow cytometry for staining with a labeled MHC tetramer complexed with the HPV16 E7 peptide recognized by the TCR. As shown in FIG. 10A, improved expression of the exemplary TCR36 was observed in CD8+ T cells with knock-out of the endogenous TCR genes (endo. TCR KO/LV), compared to in cells that retained the endogenous TCR genes (endo. TCR+/LV). Other exemplary tested TCRs also were expressed at greater levels, as assessed by E7(11-19) tetramer binding, in endogenous TCR KO CD8+ or CD4+ primary T cells compared to in primary T cells that retained the endogenous TCR genes (endo. TCR+) (FIG. 10B).

(1016) Peptide sensitivity was assessed in endogenous TCR+ or endogenous TCR KO CD8+ primary T cells that were transduced to express the exemplary TCRs, by titrating E7(11-19) peptide onto T2 cells and assessing cytokine production of TCR-expressing cells. Approximately 24 hours after incubation of recombinant TCR-expression cells with T2 target cells pulsed with various concentrations of antigen peptide, interferon gamma was measured in the supernatant. As shown in FIG. 11A, knockout of the endogenous TCR in primary human CD8+_T cells engineered with the exemplary TCR 36 improved peptide sensitivity of the recombinant TCR, consistent with increased expression of the TCR in the cells. Other exemplary TCRs also exhibited improved peptide sensitivity, based on interferon gamma production following incubation with T2 peptide pulsed cells at 10 ng/mL peptide, when expressed in endogenous TCR KO primary human CD8+ T cells compared to endogenous TCR+ primary human CD8+ T cells (FIG. 11B).

(1017) To assess function of the recombinant TCRs, cytolytic activity was assessed by incubating recombinant TCR-expressing effector cells with target cells expressing HPV 16 E7 at an effector to target (E:T) of 5:1. Target cell lysis was measured by loss of target every 2 hours using live cell imaging. As shown in FIG. 12A, in CD8+ T cells expressing the exemplary TCR 36, increased target cell lysis was observed in endogenous TCR KO CD8+ primary T cells compared to in endogenous TCR+ CD8+ primary T cells. Other exemplary TCRs also exhibited greater cytolytic activity when expressed in endogenous TCR KO CD8+ primary T cells compared to in CD8+ primary T cells that retained the endogenous TCR genes (endo. TCR+) (FIG. 12B). Interferon gamma cytokine production, monitored following incubation of recombinant TCR-expressing CD8+ effector cells with target cells expressing HPV 16 E7 at an E:T ratio of 5:1 for 48 hours, also was greater in recombinant TCR-expressing cells with knock-out of the endogenous TCR genes (endo. TCR KO) compared to cells that retained the endogenous TCR genes (endo. TCR+) (FIG. 12C).

(1018) The results were consistent with an observation that in many of the exemplary recombinant TCRs tested, knock-out of the endogenous TCR resulted in increased expression, peptide sensitivity and function of the exemplary recombinant TCRs.

Example 11: Recombinant TCR-Expressing CD4+ Cell Mediated Anti-Tumor Response

(1019) The anti-tumor response of CD4+ and CD8+ cells expressing a recombinant TCR was assessed in a mouse model.

(1020) A. Anti-Tumor Response

(1021) A mouse model with tumor cells was generated by subcutaneous injection of squamous cell carcinoma cell line UPCI:SCC152 (ATCC? CRL-3240?) cells. Primary CD4+ cells, CD8+ cells or a mixture of CD4+ and CD8+ cells, transduced with a vector encoding a reference TCR capable of binding to HPV E7(11-19) (described in International PCT Publication No. WO 2015/184228; the reference TCR contains a mouse constant region), were administered 39 days after injection of the tumor cells. The mean tumor volume was assessed over time, up to 63 days after injection of the tumor.

(1022) As shown in FIG. 13, tumor volume was reduced in mice administered CD4+ recombinant reference TCR-expressing cells alone (inverse triangle), CD8+ recombinant reference TCR-expressing cells alone (triangle), or a mixture of CD4+ and CD8+ recombinant reference TCR-expressing cells (square), compared to in mice that did not receive any treatment (circle). These results were consistent with an observation that administration of CD4+ recombinant TCR-expressing cells alone contribute to an anti-tumor response, although the effect of administering a combination of CD4+ and CD8+ recombinant TCR-expressing cells was greater.

Example 12: Generation and Assessment of Engineered T Cells Expressing a Recombinant T Cell Receptor (TCR) by Targeted Knock-In or Random Integration of Sequences Encoding the TCR

(1023) Polynucleotides encoding exemplary recombinant T cell receptors (TCRs) were introduced into T cells with genetic disruption at the endogenous gene loci that encode the T cell receptor alpha (TCR?) chain, by CRISPR/Cas9 mediated gene editing and targeted integration at the site of genetic disruption via homology-dependent repair (HDR), or by random integration via lentiviral transduction.

A. Recombinant TCR Transgene Constructs

(1024) Exemplary template polynucleotides were generated for targeted integration by HDR of a transgene containing nucleic acid sequences encoding one of two exemplary recombinant TCRs. The general structure of the exemplary template polynucleotides were as follows: [5 homology arm]-[transgene sequences]-[3 homology arm]. The homology arms included approximately 600 bp of nucleic acid sequences homologous to sequences surrounding the target integration site in exon 1 of the human TCR ? constant region (TRAC) gene (5 homology arm sequence set forth in SEQ ID NO:1343; 3 homology arm sequence set forth in SEQ ID NO:1344).

(1025) The transgene included nucleic acid sequences encoding the ? and ? chains of an exemplary recombinant TCR that recognizes an epitope of the human papilloma virus (HPV) 16 oncoprotein E7 (TCR 49), in which the sequences encoding the TCR? and TCR? chains were separated by a 2A ribosome skip element. The nucleotide sequences encoding TCR 49 also was modified by codon optimization and by mutation(s) to promote the formation of a non-native disulfide bond in the interface between the TCR constant domains to increase pairing and stability of the TCR, as described in Example 4. The non-native disulfide bond was promoted by modifying the TCR chains at residue 48 in the TCR alpha chain constant region (C?) region from Thr to Cys and residue 57 of the TCR beta chain constant region (C?) region from Ser to Cys (see Kuball et al. (2007) Blood, 109:2331-2338).

(1026) The transgene also included either a) the human elongation factor 1 alpha (EF1?) promoter to drive the expression of the recombinant TCR-encoding sequences (sequence set forth in SEQ ID NO:1345); or b) sequences encoding a P2A ribosome skip element (sequence set forth in SEQ ID NO:1346) upstream of the recombinant TCR-encoding sequences, to drive expression of the recombinant TCR from the endogenous TCR? locus upon HDR-mediated targeted integration in-frame into the human TCR ? constant region (TRAC) gene.

(1027) For targeted integration by HDR, adeno-associated virus (AAV) vector constructs containing the template polynucleotides described above were generated. AAV stocks were produced by triple transfection of an AAV vector that included the template polynucleotide, serotype helper plasmid and adenoviral helper plasmid into a 293T cell line. Transfected cells were collected, lysed and AAV stock was collected for transduction of cells.

(1028) As control, for random integration, nucleic acid sequences encoding the exemplary recombinant TCR transgene constructs described above, or sequences encoding a reference TCR capable of binding to HPV 16 E7 but containing mouse C? and the C? regions (described in International PCT Publication No. WO 2015/184228), under the control of the EF1? promoter, were incorporated into an exemplary HIV-1 derived lentiviral vector. Pseudotyped lentiviral vector particles were produced by standard procedures by transiently transfecting HEK-293T cells with the resulting vectors, helper plasmids (containing gagpol plasmids and rev plasmid), and a pseudotyping plasmid and used to transduce cells.

B. Generation of Engineered T Cells

(1029) Primary human CD4+ and CD8+ T cells from a human donor was isolated by immunoaffinity-based selection from human peripheral blood mononuclear cells (PBMCs) obtained from healthy donors. The isolated CD4+ and CD8+ cells were stimulated for 72 hours at 37? C. by culturing with an anti-CD3/anti-CD28 reagent at a 1:1 bead:cell ratio in media containing human serum, IL-2, IL-7 and IL-15. For introducing a genetic disruption at the endogenous TRAC locus by CRISPR/Cas9-mediated gene editing, the anti-CD3/anti-CD28 reagent was removed, and the cells were electroporated with 2 ?M ribonucleoprotein (RNP) complexes containing Streptococcus pyogenes Cas9 and a guide RNA (gRNA) with the targeting domain sequence GAGAAUCAAAAUCGGUGAAU (SEQ ID NO:1048), which targets a genetic disruption within exon 1 of the endogenous TCR ? constant region (TRAC) gene. Following electroporation, cells were mixed with media containing AAV preparation containing the HDR template polynucleotide encoding the exemplary recombinant TCR under the control of the EF1? promoter for transduction (HDR KO). As controls, cells were treated under the same conditions used for electroporation but without addition of an RNP (mock KO), transduced with a lentiviral vector encoding the recombinant TCR (Lenti), or a reference TCR capable of binding to HPV 16 E7 but containing mouse C? and the C? regions (Lenti Ref), or transduced with a lentiviral vector encoding the recombinant TCR and also electroporated with RNP complexes targeting a genetic disruption at the TRAC locus (Lenti KO). Following transduction, the cells were cultured for approximately 7 days in media containing human serum and IL-2, IL-7 and IL-15.

C. Expression of TCRs

(1030) On day 7 after electroporation, the cells were assessed by flow cytometry for staining with an anti-CD3 antibody, an anti-CD4 antibody, an anti-CD8 antibody, an anti-Vbeta22 antibody specific the recombinant TCR, and with a peptide-MHC tetramer complexed with the HPV16 E7 peptide.

(1031) The results for TCR 49 expressing CD8+ cells are shown in FIGS. 17A-17C. As shown, the cells expressing TCR 49 by HDR-mediated targeted integration at the TRAC locus exhibited the highest proportion of cells bound by the tetramer (FIG. 17A) and highest mean fluorescence intensity of tetramer staining in CD8+ cells (FIG. 17B). Among the CD8+ cells bound by the tetramer, the extent of binding by the tetramer was generally more uniform in cells that were subjected to HDR-mediated integration compared to random integration by lentiviral transduction, as shown by lower coefficient of variation (the standard deviation of signal within a population of cells divided by the mean of the signal in the respective population; see FIG. 17C).

(1032) In another experiment using substantially the same method as described above, staining for the TCR, using the anti Vbeta22 antibody specific for the recombinant TCR or the peptide-MHC tetramer, demonstrated higher expression of TCR49 in CD8+ primary human T cells that were knocked out for the endogenous TCR either by transduction with a lentiviral vector encoding the recombinant TCR and electroporation with RNP complexes targeting a genetic disruption at the TRAC locus (Lenti KO) or by site-directed insertion of the recombinant TCR into the TRAC locus (HDR KO) (FIG. 18A). Assessment of density, as measured using the Bangs Lab method, included labeling single-color fluorescence reference standards for flow cytometry with the same fluorophores used to label cells and generating a calibration curve to associate fluorescence channel values to standardized fluorescence intensity units. Receptor density was determined in relation to the calibration curve. The assessment of density based on tetramer (FIG. 18B) or V?22+ (FIG. 18C) demonstrated increased TCR density on T cells in which the recombinant TCR was introduced by site-directed targeted insertion of the recombinant TCR by HDR(HDR KO).

D. Cytolytic Activity and Cytokine Production

(1033) Cytolytic activity and cytokine production of cells engineered to express recombinant TCR 49 by HDR or by random integration as described above were assessed after incubating with target cells expressing HPV 16 E7 in vitro.

(1034) Cytolytic activity was assessed by culturing recombinant TCR-expressing effector cells with target cells expressing HPV 16 E7 labeled with NucLight Red (NLR) at an effector to target (E:T) ratio of 10:1, 5:1 and 2.5:1. The ability of the T cells to antigen-specifically lyse the target cells was assessed by measuring the loss of labeled target cells every 2 hours up to 44 hours post co-culture. Cytolytic activity was determined from the average from 2 donors in each group, of the area under the curve (AUC) of % killing, normalized to Vbeta expression, and compared to mock transduction control. Cytokine production was measured following incubation of recombinant TCR-expressing effector cells with target cells. Interferon-gamma (IFN?) and interleukin-2 (IL-2) secretion in the supernatant was determined by ELISA, normalized to Vbeta expression and averaged for the 2 donors in each group.

(1035) The results for TCR 49 are shown in FIGS. 19-20, based on results from two independent human donors. The degree of killing and IFN? secretion was higher in cells in which the recombinant TCR 49 driven by the EF1? promoter was introduced by HDR-mediated targeted integration at the TRAC locus (EF1?-TCR 49 HDR KO), compared to by random integration, with (TCR 49 Lenti) or without knockout of the TRAC locus (TCR 49 Lenti KO).

E. Conclusion

(1036) In general, the results were consistent with the observation that in some cases targeted integration by HDR of nucleic acid sequences encoding the exemplary recombinant TCR resulted in higher recombinant TCR expression of the human TCR in human T cells compared to introduction of the TCR by random integration, thereby leading to higher functional activity of cells expressing the recombinant TCR.

Example 13: Generation and Assessment of Expression of Recombinant T Cell Receptors (TCR) by Targeted Knock-in or Random Integration of Sequences Encoding the TCR in T Cells with Knock-Out of Endogenous TCR? and TCR? Chains

(1037) A polynucleotide encoding one of the exemplary recombinant TCR was targeted for integration at one of the sites of genetic disruption via homology-dependent repair (HDR), or was introduced by random integration via lentiviral transduction, in cells engineered to genetically disrupt the endogenous gene loci that encode the T cell receptor alpha (TCR?) or beta (TCR?) chains or both, by CRISPR/Cas9 mediated gene editing.

(1038) For targeted integration by HDR, AAV preparations containing template polynucleotide constructs encoding the exemplary recombinant TCR 49 were generated substantially as described in Example 10, except with the following differences: an additional AAV construct was generated containing the MND promoter (sequence set forth in SEQ ID NO:1347), which is a synthetic promoter that contains the U3 region of a modified MoMuLV LTR with myeloproliferative sarcoma virus enhancer, to control expression of the recombinant TCR-encoding sequences.

(1039) For random integration, lentiviral preparations containing nucleic acid sequences encoding the exemplary recombinant TCR 49 (codon optimized and cysteine-modified as described in Example 4; Lenti human) were generated generally as described in Example10. For these studies, the lentiviral transduction construct further contained a polynucleotide encoding a truncated receptor separated from the recombinant TCR transgene by a sequence encoding a T2A ribosome skip sequence for expression of both the recombinant TCR and the truncated receptor from the same construct; the truncated receptor was for use as a surrogate marker for transduction. As a control, a polynucleotide encoding a chimeric TCR was generated where the C? and the C? of the recombinant TCR were replaced by constant regions from a mouse TCR (mouse C? sequence set forth in SEQ ID NO:1012; mouse C? sequence set forth in SEQ ID NO:1013; Lenti mouse) or the cells were subject to mock transduction (mock transd.).

(1040) Primary human CD4+ and CD8+ T cells were isolated and engineered to introduce a genetic disruption at the endogenous TRAC and TRBC loci by CRISPR/Cas9-mediated gene editing and transduced with the AAV preparations containing template polynucleotides for HDR or lentiviral preparations for random integration, generally as described in Example 10B above, except that the cells also were also disrupted at the endogenous TRBC locus (TRAC/TRBC KO, interchangeably designated as TCR?? KO). Cells were electroporated with ribonucleoprotein (RNP) complexes containing the TRAC-targeting guide RNA (gRNA) described in Example 10B (containing the targeting domain sequence set forth in SEQ ID NO:1048) and an RNP containing a gRNA targeting a consensus target site sequence common to exon 1 of both TCR ? constant regions 1 and 2 (with the targeting domain sequence GGCCUCGGCGCUGACGAUCU (SEQ ID NO:1053)). Following electroporation, the cells were mixed with media containing AAV preparations for transduction of exemplary TCR 49 by HDR, under control of EF1? promoter (TCR?? KO/HDR EF1?) or MND promoter (TCR?? KO/HDR MND).

(1041) As controls, isolated primary CD4+ and CD8+ T cells were transduced with a lentiviral preparation encoding the exemplary recombinant TCR 49 (TCR?? WT/Lenti human) or the chimeric receptor containing a mouse constant region (TCR?? WT/Lenti mouse, and treated under the same conditions used for electroporation but without addition of an RNP (Mock KO; also designated as TCR?? WT or eletro ctrl), or transduced with a lentiviral preparation encoding the exemplary recombinant TCR 49 and subject to electroporation with RNP complexes to knock out TRAC and TRBC loci (TCR?? KO/Lenti human).

(1042) The cells were subsequently cultured for four (4) days, then assessed by flow cytometry for staining with an anti-CD3 antibody, an anti-Vbeta22 antibody that recognizes recombinant TCR 49, and with a peptide-MHC tetramer complexed with the antigen recognized by the recombinant TCR (HPV16 E7 peptide). The cells also were co-stained for CD8 or CD4.

(1043) The results are shown in FIGS. 21A-21F. As shown in FIGS. 21A and 21B, CRISPR/Cas9 mediated knockout (KO) of TRAC and TRBC (panel labeled TCR?? KO in figures) resulted in almost complete disruption of TCR expression in CD8+ cells as observed by the absence of CD3 staining in cells subjected to KO and mock transduction (panel labeled TCR?? KO/mock transd.). Expression of the recombinant TCR (as indicated by cells stained by Vbeta22 antibody or cells positive for tetramer staining among CD8+ cells) was slightly improved following lentiviral transduction in cells that were KO for the endogenous TCR (TCR?? KO/lenti human) compared to cells that retained expression of the endogenous TCR (TCR?? WT/lenti human). In cells retaining the endogenous TCR, recombinant TCR expression was improved by lentiviral transduction of a recombinant TCR containing a mouse constant domain compared to lentiviral transduction of a fully human recombinant TCR (compare TCR?? WT/lenti human and TCR?? WT/lenti mouse).

(1044) HDR-mediated targeted knock-in of the recombinant TCR and KO of the endogenous TCR resulted in a substantially greater proportion of cells expressing the recombinant TCR than observed following lentiviral transduction (first two left panels designated HDR compared to TCR?? KO/lenti human in FIGS. 21A and 21B). The geometric mean fluorescence (gMFI) of recombinant TCR expression, as assessed by Vbeta22 or tetramer staining in CD8+ cells (FIG. 21C) or Vbeta22 staining in CD4+ cells (FIG. 21D), also was substantially higher in cells subjected to HDR compared to lentiviral transduction. The degree of recombinant TCR expression by HDR was similar whether the recombinant TCR was under the control of the EF1? or MND promoter.

(1045) Among the cells that were positive for expression of the recombinant TCR, the extent of expression was generally more uniform or tighter in cells that were subjected to HDR-mediated targeted integration compared to random integration lentiviral transduction (see FIGS. 21A and 21B). As shown in FIG. 21E and FIG. 21F, a lower coefficient of variation (the standard deviation of signal within a population of cells divided by the mean of the signal in the respective population) of recombinant TCR expression as determined by peptide-MHC tetramer binding and Vbeta22 expression, respectively, was observed in CD8+ cells that were subjected to HDR-mediated integration compared to random integration. The results are consistent with a finding that targeted knock-in of a recombinant TCR into the endogenous TCR? locus, in combination with knock out of the endogenous TCR?? chains, results in a higher and a more uniform level of expression in population of cells engineered to express the recombinant TCR compared to other methods.

Example 14: Assessment of HDR-Mediated Knock-In of Sequences Encoding a Recombinant T Cell Receptor (TCR) in T Cells with Knock-Out of Endogenous TCR? or TCR? Chains or Both

(1046) To further assess recombinant TCR expression by HDR, nucleic acid sequences encoding an exemplary recombinant TCR into the TRAC locus was targeted for integration in cells containing a dual knock-out of the TRAC and TRBC loci, knock-out of only the TRAC locus or knock-out of only the TRBC locus.

(1047) A. Recombinant TCR Transgene Constructs and Generation of Engineered Cells

(1048) These studies were carried out using AAV (for HDR) and lentiviral constructs (for random integration) encoding the exemplary TCR 49 (codon optimized and cysteine-modified as described in Example 4) substantially as described in Examples 10 and 11, except with the following differences: lentiviral constructs were generated containing a polynucleotide encoding the recombinant TCR under the operable control of the EF1? or the MND promoter. A lentiviral construct containing a polynucleotide encoding the recombinant TCR 49 under the operable control of the EF1? promoter, and truncated receptor separated from the recombinant TCR transgene by a sequence encoding a T2A ribosome skip sequence, also was generated for comparison.

(1049) For targeted integration by HDR, primary human CD4+ and CD8+ T cells were stimulated, cultured and subject to electroporation with ribonucleoprotein (RNP) complexes containing only TRAC-targeting gRNA, only TRBC-targeting gRNA, or a mixture of both RNPs containing TRAC-targeting gRNA and RNPs containing TRBC-targeting gRNA generally as described in Examples 10 and 11 After electroporation, the cells were transduced with AAV preparations containing polynucleotides that encoded the recombinant TCR for targeting to the endogenous TRAC locus, generally as described above.

(1050) For random integration, the primary human CD4+ and CD8+ T cells were thawed, stimulated and cultured substantially as described in Examples 10 and 11, followed by transduction with a lentiviral preparation that encoded the recombinant TCR. In this study, the lentivirus preparations were transduced into primary T cells that retained the endogenous TCR. As a control, cells were treated under the same conditions used for lentiviral transduction but without addition of lentivirus (mock transduction).

(1051) B. Expression of TCRs

(1052) The cells were subsequently cultured for 4-10 additional days, and assessed by flow cytometry after staining with an anti-CD3 antibody, an anti-Vbeta22 antibody specific for the recombinant TCR 49, and with a peptide-MHC tetramer complexed with the antigen recognized by the TCR (HPV16 E7 peptide). The cells also were co-stained for CD8 or CD4.

(1053) The results for CD3 staining are shown in FIGS. 22A-22C, for tetramer staining is shown in FIGS. 23A-23C, and for Vbeta22 staining is shown in FIGS. 24A-24D.

(1054) As shown in FIGS. 22A and 22C, electroporation with mixtures of RNPs complexed with gRNAs targeting TRAC and RNPs complexed with gRNAs targeting TRBC resulted in efficient knock-out of the endogenous TCR as evidenced by the absence of CD3 surface expression (see panel labeled KO/mock transd. in FIG. 22A; see also group labeled KO mock FIG. 22C, which shows the percentage of CD3+CD8+ cells among CD8+ cells). The degree of KO with RNPs targeting both TRAC and TRBC was greater than for cells electroporated with RNP complexed with gRNA targeting only TRAC or only TRBC, which is consistent with an observation that dual-targeting of both the constant domains of TCR chains ? and ? improves the efficiency of disrupting endogenous TCR expression. In cells transduced with lentiviral vectors in which no disruption of the endogenous TCR was carried out, CD3 expression was similar in all tested conditions (FIGS. 22B and 22C). As shown in FIGS. 22A and 22C, CD3 expression also was similar among cells in which the recombinant TCR was introduced by HDR, which is consistent with TCR/CD3 surface expression in cells introduced with the recombinant TCR.

(1055) As shown in FIGS. 23A and 23C, the proportion of CD8+ cells that bound the peptide-MHC tetramer, indicated recombinant TCR expression, were higher under conditions in which HDR was carried out in cells knocked out for both TRAC and TRBC as compared to TRAC only (compare top and middle rows in FIG. 23A; compare TRAC & TRBC with TRAC only in FIG. 23C). As shown in FIG. 23C, similar results were observed on days 7 and 13. Similar expression of the recombinant TCR was observed in cells whether HDR was carried out with a construct for integration under the control of an exogenous EF1? or MND promoter or under the control of the endogenous TCR promoter (P2A-containing construct). As shown in FIG. 23B and FIG. 23C, fewer cells expressed the recombinant TCR, as assessed by tetramer staining, following lentiviral-mediated transduction, regardless of the presence of a truncated receptor in lentiviral constructs.

(1056) As shown in FIGS. 24A-24C, similar to the results above, expression of the recombinant TCR on CD8+ T cells was observed when directly staining for the recombinant TCR with an antibody that specifically recognizes the Vbeta chain of the recombinant TCR. Staining with anti-Vbeta, which also is capable of detecting the recombinant TCR on CD4+ T cells (CD8 negative population), also showed that expression of the recombinant TCR was observed in CD4+ cells (FIG. 24A and FIG. 24D).

(1057) For all methods of assessing recombinant TCR expression shown above (anti-CD3, tetramer and anti-Vbeta22), the results above also showed that targeted integration of the recombinant TCR to the TRAC via HDR was specific for nuclease-induced DNA break at the TRAC locus, as the cells electroporated with TRBC-targeting RNP did not express the recombinant TCR (see TRBC only condition in FIGs).

(1058) C. Cytolytic Activity and Cytokine Production

(1059) Cytolytic activity and cytokine production of CD8+ cells engineered to express recombinant TCR 49 by HDR or by random integration as described above were assessed after incubating with target cells expressing HPV 16 E7 in vitro. In addition to cells described above, primary human CD8+ cells transduced with a lentivirus encoding a reference TCR capable of binding to HPV 16 E7 but containing mouse C? and the C? regions, also was assessed.

(1060) Cytolytic activity was assessed by incubating recombinant TCR-expressing effector cells with target cells expressing HPV 16 E7 at an effector to target (E:T) ratio of 10:1, 5:1 and 2.5:1. The ability of the T cells to antigen-specifically lyse the target cells was assessed 4 hours post co-culture. Cytolytic activity was determined from the area under the curve (AUC) of % killing, normalized to Vbeta expression and compared to mock transduction control. The results are shown in FIG. 25. The degree of killing was higher in cells in which the recombinant TCR was introduced by HDR-mediated targeted integration compared to by random integration, which is consistent with a finding that higher expression of the recombinant TCR in cells results in higher functional activity.

(1061) Cytokine production was also monitored following incubation of recombinant TCR-expressing CD8+ effector cells with target cells expressing HPV 16 E7 at an E:T ratio of 10:1 and 2.5:1 for 48 hours. IFN? secretion in the supernatant was determined by ELISA and was normalized to Vbeta22 expression for each group. The results are shown in FIG. 26. Similar to the results above for cytolytic activity, a greater production of IFN? was observed by cells subjected to HDR-mediated integration compared to random integration. In the cytolytic activity assay and assessment of IFN? secretion, the functional activity of cells expressing the recombinant TCR, by HDR-mediated integration, was similar to the activity of cells expressing, via lentiviral transduction, a reference TCR containing mouse constant domains.

(1062) Proliferation of the recombinant TCR-expressing cells was assessed following incubation with SCC152 target cells or T2 target cells pulsed the antigen peptide was assessed. The cells were labeled with CellTrace? violet (ThermoFisher) dye. Division of live T cells was indicated by CellTrace? violet dye dilution, as assessed by flow cytometry.

(1063) The results of various functional assays are depicted in FIG. 27. As shown in the heat map depicting the relative activity of recombinant TCR-expressing cell populations in various functional activities (AUC of % killing at E:T ratios of 10:1, 5:1 and 2.5:1 (designated AUC), tetramer binding in CD8+ cells on days 7 and 13 (designated tetramer CD8), proliferation assay (designated CTV count) using SCC152 cells or T2 target cells pulsed the antigen peptide and secretion of IFN? from CD8+ cells (designated CD8 secreted IFNg)), functional activity of cells with recombinant TCR targeted for knock-in at the endogenous TCR? chain constant domain locus and knockout of the endogenous TCR?? genes or TCR? gene was generally observed to be higher compared to cells where the polynucleotide encoding the recombinant TCR was randomly integrated.

(1064) In general, the results were consistent with the observation that targeted integration by HDR results in higher recombinant TCR expression of the human TCR in human T cells compared to introduction of the TCR by random integration, thereby leading to higher functional activity of cells expressing the recombinant TCR.
