Background

PD1 is an inhibitory cell membrane surface receptor from the immunoglobulin superfamily. Involved in the regulation of T cell function during immunity and tolerance, PD1 inhibits T cell effector functions upon ligand binding. The protein is expressed in pro-B-cells and is thought to play a role in their differentiation as well. Studies have also suggested that this gene product may also contribute to the prevention of autoimmune diseases.
