Immunobiology
Anti-PD-1 is a type of monoclonal antibody used in cancer immunotherapy that blocks the programmed cell death protein 1 (PD-1) receptor on T cells, enhancing the immune system's ability to recognize and destroy cancer cells. By inhibiting this checkpoint protein, anti-PD-1 therapy can reactivate T cells that have been suppressed by tumors, allowing for a more robust immune response against cancer.
