The T cell receptor β-chain is expressed in two isoforms, TRBC1 and TRBC2, with clonally expanded mature T cell lymphomas expressing one of them exclusively, while healthy T cells randomly express either TRBC1 or TRBC2. Here authors show structure-based design of a TRBC2-specific antibody, and depletion of malignant T cells carrying TRBC1 or TRBC2 with CAR-T cells against the cognate receptor chain in murine models.
