Description

Programmed death-1 (PD-1), also known as programmed cell death 1 (PDCD1) or CD279, is a single pass type I transmembrane glycoprotein of the Ig superfamily. It is an immunoreceptor in the CD28/CTLA-4 family with an IgV-type extracellular domain showing 21–33% sequence identity with CTLA-4, CD28 and ICOS.  Members of the CD28/CTLA-4 family have been shown to either promote T cell activation (CD28 and ICOS) or inhibit T cell activation (CTLA­4 and PD­1).  The cytoplasmic domain of PD-1 contains two tyrosine residues, a membrane-proximal immunoreceptor tyrosine-based inhibitory motif (ITIM) and an immunoreceptor tyrosine-based switch motif (ITSM). ITIM is widely found in immunoinhibitory receptors and the membrane-proximal tyrosine residue may play a central role for the inhibitory function of PD-1. PD-1 negatively regulates antigen receptor signaling by recruiting protein tyrosine phosphatase upon engaging with either of two ligands, PD-L1 or PD-L2. It inhibits the T-cell proliferation and production of related cytokines such as IL-1, IL-4, IL-10 and IFN-γ. PD-1 is involved in lymphocyte clonal selection and peripheral tolerance, and thus contributes to the prevention of autoimmune diseases. As a negative regulator of T- cell effector mechanisms, PD-1 may lead to suppression of anti-tumor immunity. Blockade of PD-1 inhibitory activity with antibodies enhances anti-tumor immunity in vivo.  PD-1 has been proposed as a promising target for cancer immunotherapy.
