|Description||Programmed Cell Death Protein 1 (PD-1), is cell surface receptor expressing on T cells and pro-B cells. The binding of PD-1 to its two ligands, PD-L1 and PD-L2, could result in down-regulation of the immune system by inhibiting the T-cell activation process. Thus, PD-1 is an important immune checkpoint and a popular target for therapeutic antibodies against many cancers.|
