Abstract

PD-1 deficiency causes a variety of autoimmune diseases. Inhibitory signaling through the PD-1 receptor might therefore be involved in the regulation of peripheral tolerance. The constitutive expression of PD-1 ligands (PD-L1 and PD-L2) on parenchymal cells of heart, lung and kidney suggests that the PD-1-PD-L system could provide unique negative signaling to help prevent autoimmune diseases.
