Systems and methods to link CD40 signaling to antigen binding, independently of CD40 ligand binding are described. The systems and methods include fusion proteins including an extracellular antigen binding domain linked to an intracellular CD40 signaling domain.

Provided herein are methods, kits and compositions for the treatment and/or prevention of ovarian cancer through the induction of an immune response against Anti-Mullerian Hormone Receptor, Type II (AMHR2).

RNA molecules comprising a guide sequence portion having 17-50 contiguous nucleotides containing nucleotides in the sequence set forth in any one of SEQ ID NOs: 1-1538 and compositions, methods, and uses thereof.

Described herein are constructs used for B-cell genomic engineering and for expression of a transgene and/or for modulation of B cell function.

Compositions and methods are disclosed herein for producing one or more immunoglobulins in an isolated cytotoxic B lymphocyte cell line. An isolated cell line includes an isolated B lymphocyte cell line capable of expressing at least one exogenously incorporated membrane immunoglobulin capable of binding to a first antigen and at least one endogenous secreted immunoglobulin capable of binding to a second antigen, and further capable of expressing at least one exogenously incorporated recombinant B cell receptor that signals for expression of cytotoxic effector molecules.

Provided herein are engineered B cells, such as for adoptive cell therapy. In some aspects, also provided are methods and compositions for engineering and producing the cells, compositions containing the cells, and methods for their administration to subjects. In some embodiments, the cells are engineered to produce and/or secrete an exogenous protein, such as a therapeutic protein, including antibodies and antigen-binding fragments thereof. In some aspects, features of the cells and methods provide for increased or improved activity, efficacy and/or persistence of the cells.

The invention provides HPV agonist epitopes, which can be used as a peptide, polypeptide (protein), and/or in a vaccine or other composition for the prevention or therapy of HPV infection and/or cancer. The invention further provides a nucleic acid encoding the peptide or polypeptide (protein), a vector comprising the nucleic acid, a cell comprising the peptide, polypeptide (protein), nucleic acid, or vector, and compositions thereof.

Disclosed in the present application are: a method for preparing in vitro/ex vivo antigen-specific cytotoxic T-cells by using B cells treated with biological response modifier; and a use thereof. The cytotoxic T-cells prepared by the method of the present application can be used advantageously for treating infectious disease and cancer and the like.

The present invention relates to a method for obtaining stable pseudotyped lentiviral particles including a heterologous gene of interest, comprising the following steps: a) transfecting at least one plasmid in appropriate cell lines, wherein said at least one plasmid comprises the gene of interest, the rev. gag and pol genes, and a sequence coding for an ERV syncytin, wherein the rev, gag and pol genes are retroviral genes; b) incubating the transfected cells obtained in a), so that they produce the stable pseudotyped lentiviral particles in the supernatant; and c) harvesting and concentrating the stable lentiviral particles obtained in b). The present invention also relates to a method to transduce immune cells using lentiviral vectors pseudotyped with an ERV syncytin glycoprotein. The method can be performed on non-stimulated blood cells or on cells stimulated briefly with IL7, and the cells can be expanded. The stable pseudotyped lentiviral particles obtained are particularly useful in gene therapy.

Disclosed herein are chimeric antigen receptor (CAR) polypeptides that can be used with adoptive cell transfer to target and kill TAG-72-expressing cancers. Also disclosed are immune effector cells, such as T cells or Natural Killer (NK) cells, that are engineered to express these CARs. Therefore, also disclosed are methods of providing an anti-tumor immunity in a subject with a TAG-72-expressing cancer that involves adoptive transfer of the disclosed immune effector cells engineered to express the disclosed CARs.
