  FC experiment of human PBMCs using 65119-1-Ig

  1x10^6 PHA treated (3 day) human PBMCs were surface stained with 0.2 ug Anti-Human PD-1/CD279 (65119-1-Ig, Clone:J110) (right) or Mouse IgG1 Isotype Control (left). 1x10^6 untreated human PBMCs were surface stained with 0.2 ug Anti-Human PD-1/CD279 (65119-1-Ig, Clone:J110) (center). All cells were then stained with CoraLite®647-conjugated F(ab')2 Fragment Donkey Anti-Mouse IgG (H+L) (SA00014-8) followed by staining with CL488 Anti-Human CD3. Cells were not fixed. Lymphocytes were gated.

Background Information

Programmed cell death 1 (PD-1, also known as CD279) is an immunoinhibitory receptor that belongs to the CD28/CTLA-4 subfamily of the Ig superfamily. It is a 288 amino acid (aa) type I transmembrane protein composed of one Ig superfamily domain, a stalk, a transmembrane domain, and an intracellular domain containing an immunoreceptor tyrosine-based inhibitory motif (ITIM) as well as an immunoreceptor tyrosine-based switch motif (ITSM) (PMID: 18173375). PD-1 is expressed during thymic development and is induced in a variety of hematopoietic cells in the periphery by antigen receptor signaling and cytokines (PMID: 20636820). Engagement of PD-1 by its ligands PD-L1 or PD-L2 transduces a signal that inhibits T-cell proliferation, cytokine production, and cytolytic function (PMID: 19426218). It is critical for the regulation of T cell function during immunity and tolerance. Blockade of PD-1 can overcome immune resistance and also has been shown to have antitumor activity (PMID: 22658127; 23169436).
