PD-1 is an immune checkpoint and guards against autoimmunity through two mechanisms. First, it promotes apoptosis (programmed cell death) of antigen -specific T-cells in lymph nodes. Second, it reduces apoptosis in regulatory T cells (anti-inflammatory, suppressive T cells). [6] [7] Prikaži več Programmed cell death protein 1, also known as PD-1 and CD279 (cluster of differentiation 279), is a protein on the surface of T and B cells that has a role in regulating the immune system's response to the cells of the … Prikaži več In a screen for genes involved in apoptosis, Yasumasa Ishida, Tasuku Honjo and colleagues at Kyoto University in 1992 discovered and named PD-1.
