Immune checkpoint inhibitor; the panel on the left shows the binding of proteins PD-L1 (on the tumor cell) to PD-1 (on the T cell), which keeps T cells from killing tumor cells in the body. Also shown are a tumor cell antigen and T cell receptor. The panel on the right shows immune checkpoint inhibitors (anti-PD-L1 and anti-PD-1) blocking the binding of PD-L1 to PD-1, which allows the T cells to kill tumor cells.
Immune checkpoint inhibitor. Certain proteins, such as PD-1 and PD-L1, are found on immune system cells and some tumor cells. PD-1 and PD-L1 help keep immune responses in check. The binding of PD-L1 (on tumor cells) to PD-1 (on T cells) keeps T cells from killing tumor cells in the body (left panel). Blocking the binding of PD-L1 to PD-1 with an immune checkpoint inhibitor (anti-PD-L1 or anti-PD-1) allows the T cells to kill tumor cells (right panel).
