The invention provides CARs (CARs) that specifically bind to BCMA (B-Cell Maturation Antigen). The invention further relates to engineered immune cells comprising such CARs, CAR-encoding nucleic acids, and methods of making such CARs, engineered immune cells, and nucleic acids. The invention further relates to therapeutic methods for use of these CARs and engineered immune cells for the treatment of a condition associated with malignant cells expressing BCMA (e.g., cancer).

Provided herein are modified T lymphocytes comprising chimeric receptors and methods thereof.

Disclosed herein are methods for treating cancer comprising administering CAR-modified immune cells and at least one Retinoic Acid Receptor agonist.

Disclosed herein are methods for treating cancer comprising administering CAR-modified immune cells and at least one Retinoic Acid Receptor agonist.

Provided herein are T-cell receptor (TCR) fusion proteins (TFPs), T-cells engineered to express one or more TFPs, and methods of use thereof for the treatment of diseases, including cancer.

Provided herein are T-cell receptor (TCR) fusion proteins (TFPs), T-cells engineered to express one or more TFPs, and methods of use thereof for the treatment of diseases, including cancer.

Provided are a human PD-1 knockdown siRNA, a recombinant expression CAR-T vector, a preparation method thereof, and an application of the same, A PD-1 knockdown siRNA expression cassette and an siRNA expression product thereof can be applied to a CAR-T therapy of multiple myeloma (MM) for eliminating or alleviating a tumor immune escape mechanism, and in the suppression of an immune escape mechanism in a CAR-T therapy of a tumor, such as pancreatic cancer, brain glioma, and myeloma.

Disclosed herein are methods of providing an anti-tumor immunity in a subject with a CD83-expressing cancer that involves adoptive transfer of the immune effector cells engineered to express chimeric antigen receptor (CAR) polypeptides that selectively bind CD83-expressing cancers. Also disclosed herein are dual-CAR systems to increase safety and/or efficacy of the CAR-T cells.

Provided are engineered cells for adoptive therapy, including NK cells and T cells. Also provided are compositions for engineering and producing the cells, compositions containing the cells, and methods for their administration to subjects. In some embodiments, the cells contain genetically engineered antigen receptors that specifically bind to antigens, such as chimeric antigen receptors (CARs) and costimulatory receptors. In some embodiments, the cells include receptors targeting multiple antigens. In some embodiments, the cells include repression of one or more gene product, for example, by disruption of a gene encoding the gene product. In some embodiments, a gene encoding an antigen recognized by the engineered antigen receptor is disrupted, reducing the likelihood of targeting of the engineered cells. In some embodiments, the antigen recognized by the engineered antigen receptor is related to a tumor antigen recognized by the engineered antigen receptor.

The invention relates to chimeric antigen receptor (CAR) specific to p80 and CD146, vectors encoding the same, and recombinant T cells comprising the p80 or CD146 CAR. The invention also includes methods of administering a genetically modified T cell expressing a CAR that comprises a p80 or CD146 binding domain.
