B7-H1, PD-L1, CD274, Programmed cell death 1 ligand 1, Programmed death ligand 1, PD-L1, PDCD1 ligand 1, B7 homolog 1, B7-H1, Programmed death ligand 1, PD1L1_HUMAN.
Programmed cell death 1 ligand 1(Programmed death ligand 1, PD-L1, PDCD1 ligand 1, B7 homolog 1, B7-H1, CD274) involved in the costimulatory signal, essential for T lymphocyte proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibit T-cell proliferation and cytokine production.
