PD-1 inhibits T cell responses to cancer after binding to one of its … WebPD-1 and PD-L1 inhibitors. PD-1 is a checkpoint protein on immune cells called T cells. It normally acts as a type of “off switch” that helps keep the T cells from attacking other cells in the body. It does this when it attaches to PD-L1, a protein on some normal (and cancer) cells. When PD-1 binds to PD-L1, it basically tells the T cell to ...
