T cell activation can be profoundly altered by coinhibitory and costimulatory molecules. B and T lymphocyte attenuator (BTLA) is a recently identified inhibitory Ig superfamily cell surface protein found on lymphocytes and APC. In this study we analyze the effects of an agonistic anti-BTLA mAb, PK18, on TCR-mediated T cell activation.
