Anti-PD1 antibody,Abcam,AB92484

Target data The protein expressed by the gene PDCD1 functions as an inhibitory receptor on antigen-activated T-cells, playing a critical role in the induction and maintenance of immune tolerance to self. It delivers inhibitory signals by binding to the ligands CD274/PDCD1L1 and CD273/PDCD1LG2. Tumors exploit the PDCD1-mediated inhibitory pathway to attenuate anti-tumor immunity, enabling tumor survival by evading immune system destruction. The interaction with CD274/PDCD1L1 inhibits the effector function of cytotoxic T lymphocytes (CTLs). Blocking the PDCD1-mediated pathway can reverse the exhausted T-cell phenotype and normalize the anti-tumor response, providing a rationale for cancer immunotherapy.
