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 human body by down-regulating the immune system and promoting self-tolerance by suppressing T cell inflammatory activity. This prevents autoimmune diseases, but it can also prevent the immune system from killing cancer cells. 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).
Flow cytometric analysis of human PBMC (human peripheral blood mononuclear cell) labelling Human CD279 (PD-1) antibody at 1/200 (1 μg) dilution/ (Right panel) compared with a Mouse IgG2b, κ Isotype Control / (Left panel). Goat Anti-Mouse IgG Alexa Fluor® 488 was used as the secondary antibody. Then cells were stained with CD3 - Alexa Fluor® 647 antibody separately.
