The present invention includes engineered T cell receptor (TCR) proteins, nucleic acids, vectors, host cells, methods of treating cancer, and chimeric antigen receptor expressing T cell (CAR-T) comprising an alpha chain CDR3 having the amino acid sequence of SEQ ID NO: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, or 23 and/or a beta chain CDR3 having the amino acid sequence of SEQ ID NO: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, or 24, wherein the TCR is specific for a KRAS G12>V mutation peptide, antigen-MHC binding portions, and full length portions of the same.

Methods of generating an isolated population of non-graft versus host disease (GVHD) inducing cells comprising a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance inducing cells and/or endowed with anti-disease activity, and capable of homing to the lymph nodes following transplantation, are disclosed. Cells generated by the methods, pharmaceutical compositions and methods of treatment are also disclosed.

An immunotherapy delivery system includes a hydrogel with an immunomodulatory cargo including cells encapsulated in the hydrogel, a cell adhesion motif in the hydrogel configured to reversibly adhere to and release the cells, and an immunomodulatory cargo encapsulated in the hydrogel. The hydrogel includes a polymer non-covalently crossed-linked with a plurality of nanoparticles.

Provided herein are engineered T cells, expressing a chimeric receptor comprising an antigen-binding domain fused to an endogenous invariant CD3 chain of the immunoglobulin superfamily (invariant CD3-IgSF). In some embodiments, the engineered T cells contain a modified invariant CD3-IgSF chain locus that encodes the chimeric receptor. Also provided are cell compositions containing the engineered T cells, nucleic acids for engineering cells, and methods, kits and articles of manufacture for producing the engineered cells, such as by targeting a transgene encoding a portion of a chimeric receptor for integration into an invariant CD3-IgSF chain genomic locus. In some embodiments, the engineered cells, e.g. T cells, can be used in connection with cell therapy, including in connection with cancer immunotherapy comprising adoptive transfer of the engineered cells.

An example genetically engineered natural killer (NK) cell comprises an exogenous polynucleotide sequence that includes a receptor element, an actuator element, and an effector element. The receptor element encodes a chimeric antigen receptor (CAR) comprising an extracellular antigen binding domain operably linked to a transmembrane domain, and an intracellular signaling domain, wherein the extracellular antigen binding domain recognizes a surface antigen of a target cell. The actuator element encodes a transcription factor binding site that upregulates synthesis of an effector protein. The effector element encodes the effector protein operably linked to a signal peptide, wherein, in response to the antigen binding domain of the CAR binding to the antigen of the target cell, the engineered NK cell is configured to activate and, to synthesize and secrete the effector protein.

Provided herein are gRNA comprising a targeting domain that targets CD38, which may be used, for example, to make modifications in cells. Also provided herein are methods of genetically engineered cell having a modification (e.g., insertion or deletion) in the CD38 gene and methods involving administering such genetically engineered cells to a subject, such as a subject having a hematopoietic malignancy.

Disclosed herein are methods and compositions comprising placental adherent stromal cells for treating viral infections and sequelae thereof.

The present invention relates to the provision of clinically relevant T cell receptors and T cell epitopes which are useful for immunotherapy. The present invention also relates to therapies involving immune effector cells such as T cells expressing a T cell receptor disclosed herein and/or being specific for a T cell epitope disclosed herein.

Provided are methods and compositions for obtaining functionally enhanced derivative effector cells obtained from directed differentiation of genomically engineered iPSCs. The iPSC-derived effector cells provided herein have stable and functional genome editing that delivers improved or enhanced therapeutic effects. Also provided are therapeutic compositions and the use thereof comprising the functionally enhanced derivative effector cells alone, or with antibodies or checkpoint inhibitors in combination therapies.

The disclosure is directed to methods and compositions relating to genetically engineered cells expressing chimeric antigen receptors, where the cells are mobilized lymphocytes.
