Abstract

The present disclosure relates generally to compositions and methods for improving T cell therapy. In particular, the disclosure provides polypeptides and recombinant nucleic acid constructs and/or recombinant nucleic acids encoding polypeptides having mutations capable of altering T cell signaling, cytokine production, and/or in vivo persistence in tumors of therapeutic T cells comprising the mutation. The T cell signaling can be by NFAT, NF-κB and/or AP-1 pathways. The disclosure also provides vectors and cells including the polypeptides and/or recombinant nucleic acid constructs and/or recombinant nucleic acids of the disclosure as well as methods of preparing a T cell for use in cell therapy, and methods of identifying a mutation useful for improving T cell therapy.
