Provided herein is a composition comprising, a
cell, comprising nucleic acids encoding a
chimeric antigen receptor (CAR) and one or more of
signaling proteins selected from K13-vFLIP, MC159-vFLIP, cFLIP-L, cFLIP-p22, HTLV1-Tax and HTLV2-Tax, wherein the CAR comprises an a)
extracellular antigen specific domain, b) a
transmembrane domain and c) an
intracellular signaling domain comprising an immunoreceptor
tyrosine-based activation motif (ITAM); wherein c) is located at the C-terminus of the chimeric
receptor. In some embodiments, the CAR further comprises one or more co-stimulatory domains. Also provided herein are methods for treating diseases using the compositions described herein. Further provided herein is a
kinase inhibitor for use in therapeutic methods described herein.
