Summary
PD-L1 antibody recognizes programmed death-ligand 1 (PD-L1) protein, also known as B7 homolog 1 (B7-H1) and cluster of differentiation 274 (CD274) protein. PD-L1 is found on various cancer cells and transduces immunosuppressive signals by binding to the programmed cell death protein 1 (PD-1) on effector T cells, thereby diminishing immune system attacks on malignant cells. Blocking the interaction between PD-L1 and PD-1 with PD-L1 antibodies is generating great clinical interest as a mode of immunotherapy against a number of cancers.

Background
Involved in the costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation and cytokine production.
