Targeting intracellular LMP2 with costimulatory signal-armed antibody-like TCR T cells.

ABSTRACT: Expanding the repertoire of CAR therapies to include intracellular antigens holds promise for treating a broad spectrum of malignancies. TCR-like T cells, capable of recognizing intracellular antigen-derived peptides in complex with HLA molecules (pHLA), represent a promising strategy in the field of engineered cellular therapy. This study introduced antibody-like TCR (abTCR) T cells that specifically targeted HLA-A*02:01-restricted LMP2426 peptides, a typical Epstein-Barr virus (EBV) latency II protein, for the treatment of EBV-associated lymphoproliferative diseases (EBV-LPDs). Compared with classic CAR T cells targeting the same epitope, abTCR T cells demonstrated superior efficiency, including increased CD107A expression, enhanced cytotoxicity, and elevated IFN-γ secretion, even when e
