The invention pertains to the field of adoptive cell immunotherapy. It provides with engineered immune cells comprising genetic alteration into genes which are involved into immune functions downregulation, especially in response to environment signals such as nutrients depletion. Such method allows the production of more potent immune cells in the context of tumors' microenvironment.

In one embodiment, the present disclosure provides an engineered cell having a first chimeric antigen receptor polypeptide including a first antigen recognition domain, a first signal peptide, a first hinge region, a first transmembrane domain, a first costimulatory domain, and a first signaling domain; and a second chimeric antigen receptor polypeptide including a second antigen recognition domain, a second signal peptide, a second hinge region, a second transmembrane domain, a second co-stimulatory domain, and a second signaling domain; wherein the first antigen recognition domain is different than the second antigen recognition domain.

The invention includes a chimeric autoantibody receptor (CAAR) specific for anti-muscle-specific kinase (MuSK) B cell receptor (BCR), compositions comprising the CAAR, polynucleotides encoding the CAAR, vectors comprising a polynucleotide encoding the CAAR, and recombinant cells comprising the CAAR.

The present invention relates to compositions and methods for diagnosing and treating diseases, disorders or conditions associated with dysregulated expression of FSHR. The invention provides novel peptides that specifically bind to Follicle-stimulation hormone receptor (FSHR).

Antigen binding agents (e.g., single domain antibodies) that bind guanylyl cyclase C (GCC) and chimeric antigen receptors comprising GCC antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions comprising these antigen binding agents and fragments thereof are also disclosed. The invention also provides therapeutic methods for utilizing the antibodies and antigen-binding molecules are provided herein.

The invention discloses novel RAR gamma selective agonists used in the treatment of cancer. The invention also discloses administration of RAR gamma selective agonists to mammals, including humans for the purpose of selectively activating RAR gamma receptor and treat cancer by way of activating tumor infiltrating lymphocytes.

The invention relates to methods for treatment of cancers utilizing a combination of a deoxyribonuclease enzyme and adoptive cell immunotherapy comprising cells expressing a chimeric antigen receptor (CAR) or a T cell receptor (TCR). In particular embodiments, the deoxyribonuclease enzyme can be given parenterally or encoded by a vector or secreted by a cell comprising TCR or CAR.

The invention provides methods of making immune effector cells (e.g., T cells, NK cells) that can be engineered to express a chimeric antigen receptor (CAR), compositions and reaction mixtures comprising the same, and methods of treatment using the same.

Provided herein are polynucleotides encoding chimeric antigen receptors (CARs) comprising a CD19 antigen binding domain that specifically binds to CD19 and is resistant to rituximab binding; and immune cells comprising these CD19-specific CARs, e.g., CAR-T cells. Also provided are methods of making and using these CD19-specific CARs, and immune cells comprising these CD19-specific CARs.

Provided are methods of treatment involving immunotherapy, such as T cell therapy, and administration of a tryptophan metabolism and/or kynurenine pathway modulator. In some embodiments, the method includes a combination therapy that involves administration of engineered T cells, such as chimeric antigen receptor (CAR)-expressing cells, and a tryptophan metabolism and/or kynurenine pathway modulator, such as an inhibitor of an enzyme. Also provided are engineered cells in which the expression of a molecule involved in the kynurenine pathway is modified. Also provided are methods of manufacturing engineered cells, cells, compositions, methods of administration to subjects, nucleic acids and kits for use in the methods. In some aspects, features of the methods and cells provide for increased or improved activity, activity, outcome, function, response, persistence, expansion and/or proliferation of cells for adoptive cell therapy.
