WebThe programmed cell death 1 (PD-1) surface receptor binds to two ligands, PD-L1 and PD-L2. Studies have shown that PD-1-PD-L interactions control the induction and maintenance of peripheral T cell tolerance and indicate a previously unknown function for PD-L1 on nonhematopoietic cells in protecting tissues from autoimmune attack. WebProgrammed cell death 1 (PD-1) is a negative costimulatory receptor belonging to the B7/CD28 family. PD-1 expression is induced on activated T cells, B cells, monocytes, DCs, and, at low levels, on natural killer T cells (NKT).
