Anti-PD-1 [J110]
NEW

Info

Catalogue Number 153513
Applications ELISA IHC WB
Antigen/Gene or Protein Targets PD-1
Synonyms Programmed cell death protein 1, CD279
Reactivity Human
Relevance The PD-1 protein is an inhibitory cell surface receptor involved in the regulation of T-cell function during immunity and tolerance. Upon ligand binding, inhibits T-cell effector functions in an antigen-specific manner. Possible cell death inducer, in association with other factors.

PD-1 belongs to the immunoglobulin superfamily and is expressed on T cells and pro-B cells. PD-1 binds two ligands, PD-L1 and PD-L2. PD-1, functioning as an immune checkpoint, plays an important role in down regulating the immune system by preventing the activation of T-cells, which in turn reduces autoimmunity and promotes self-tolerance. The inhibitory effect of PD-1 is accomplished through a dual mechanism of promoting apoptosis (programmed cell death) in antigen specific T-cells in lymph nodes while simultaneously reducing apoptosis in regulatory T cells (suppressor T cells).

A new class of drugs that block PD-1, the PD-1 inhibitors, activate the immune system to attack tumors and are therefore used to treat cancer.
