Biological Activity
Description
PD-L2 Protein, Human (HEK293, Fc), a second ligand for PD-1, interacts with PD-1 negatively regulates T cell proliferation, cytokine production and cytotoxic activity.
Background
Programmed death I (PD-I)-deficient mice develop a variety of autoimmune-like diseases, which suggests that this immunoinhibitory receptor plays an important role in tolerance. PD-1 ligand 2 (PD-L2) is a second ligand for PD-1. Engagement of PD-1 by PD-L2 dramatically inhibits T cell receptor (TCR)-mediated proliferation and cytokine production by CD4+ T cells. At low antigen concentrations, PD-L2-PD-1 interactions inhibit strong B7-CD28 signals. In contrast, at high antigen concentrations, PD-L2-PD-1 interactions reduce cytokine production but do not inhibit T cell proliferation. PD-L-PD-1 interactions lead to cell cycle arrest in G0/G1 but do not increase cell death. In addition, ligation of PD-1 + TCR leads to rapid phosphorylation of SHP-2, as compared to TCR ligation alone[1].
Verified Bioactivity
5 µg/mL (100 µL/well) of immoblized recombinant human PD-L2-Fc can bind human Biotin-PD-1-Fc with a linear range of 2.44-39.06 ng/mL.
