Abstract: The presently disclosed subject matter provides methods and compositions for enhancing the immune response toward cancers and pathogens. It relates to novel designs of chimeric antigen receptors (CARs) and engineered immunoresponsive cells comprising the same. The engineered immunoresponsive cells comprising the novel CARs are antigen-directed and have extended persistence without compromising function.

Abstract: The presently disclosed subject matter provides for expression cassettes that allow for expression of a globin gene or a functional portion thereof, vectors comprising thereof, and cells transduced with such expression cassettes and vectors. The presently disclosed subject matter further provides methods for treating a hemoglobinopathy in a subject comprising administering an effective amount of such transduced cells to the subject.

Abstract: The presently disclosed subject matter provides cells, compositions and methods for enhancing immune responses toward tumor antigens. It relates to cells comprising: an antigen-recognizing receptor (e.g., a chimeric antigen receptor, a TCR, or a TCR like fusion molecule); and a gene disruption of a CD70 locus. The gene disruption of the CD70 locus can improve the activity and/or efficiency of the cells.

Abstract: The presently disclosed subject matter provides chimeric antigen receptors (CARs) that specifically target CD19 and cells comprising such CD19-targeted CARs. The presently disclosed subject matter further provides uses of the CD19-targeted CARs for treatment, e.g., for treating blood cancer.

Abstract: The invention provides a T cell wherein one or more therapeutic transgenes is integrated at a within the genome of the cell such that expression of the transgene is under control of an endogenous promoter of the T cell. The invention additional provides methods of making and using such cells to treat a subject with T cell therapy. The invention also provides a T cell wherein a recombinant nucleic acid sequence encoding a chimeric antigen receptor (CAR) is integrated at a first site within the genome of the cell such that the CAR is expressed by the cell at the surface of the cell, and wherein integration of the nucleic acid encoding the CAR at the first site reduces or prevents expression of a functional T cell receptor (TCR) complex at the surface of the cell. The invention additional provides methods of making and using such cells to treat a subject with CAR therapy.

Abstract: The presently disclosed subject matter provides for chimeric receptors that target ADGRE2 and chimeric receptors that target CLEC12A. The presently disclosed subject matter also provides for cells comprising the ADGRE2-targeted chimeric receptors, cells comprising the CLEC12A-targeted chimeric receptors, and cells comprising the ADGRE2-targeted chimeric receptors and the CLEC12A-targeted chimeric receptors. The presently disclosed subject matter further provides uses of such cells for treating tumors, e.g., AML.

Abstract: The presently disclosed subject matter provides methods and compositions for enhancing the immune response toward cancers and pathogens. It relates to novel designs of T cell receptors (TCRs) and engineered immunoresponsive cells comprising the same. The novel TCR binds to an antigen in an HLA-independent manner. In certain embodiments, the novel TCR provides enhanced sensitivity for a target gene having a low expression level.
