Monoclonal Anti-PD-1 antibody produced in mouse

Programmed cell death 1 protein (PDCD1) is mapped to human chromosome 2q37.3. PDCD1 belongs to the Cluster of Differentiation 28 (CD28) family of receptors and has an immunoinhibitory domain. It is expressed in T and B lymphocytes.

raised against an ~150 amino acid recombinant protein from near the terminus terminus of mouse PD-1.

Programmed cell death 1 protein (PDCD1) modulates lymphocyte activation. Single nucleotide polymorphisms in PDCD1 is implicated in systemic lupus erythematosus, an autoimmune inflammatory disease.

Cell-mediated immune responses are initiated by T lymphocytes that are themselves stimulated by cognate peptides bound to MHC molecules on antig en-presenting cells (APC). T-cell activation is generally self-limited as activated T cells express receptors such as PD-1 (also known as PDCD-1) that mediate inhibitory signals from the APC. PD-1 can bind two different but related ligands, PDL-1 and PDL-2. Upon binding to either of these ligands, signals generated by PD-1 inhibit the activation of the immune response in the absence of "danger signals" such as LPS or other molecules associated with bacteria or other pathogens. Evidence for this is seen in PD1-null mice who exhibit hyperactivated immune systems and autoimmune diseases. Despite its predicted molecular weight, PD-1 often migrates at higher molecular weight in SDS-PAGE.
