Allogeneic Gamma-delta T-lymphocytes TCB-008

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** A preparation of ex vivo-expanded, allogeneic T-lymphocytes that express only gamma chain and delta chain T-cell receptors (TCRs), with potential immunomodulating and antineoplastic activities. Upon administration of the allogeneic gamma-delta T-lymphocytes TCB-008, these cells secrete interferon-gamma (IFN-g) and exert direct killing of tumor cells. In addition, these cells activate the immune system to exert a cytotoxic T-lymphocyte (CTL) response against tumor cells. Gamma-delta T-lymphocytes play a key role in the activation of the immune system and do not require major histocompatibility complex (MHC)-mediated antigen presentation to exert their cytotoxic effect.
