IL‑10 Inhibition of IL‑1 beta secretion and Neutralization by Human IL‑10 R beta Antibody. Recombinant Human IL‑10 (Catalog # 217-IL) inhibits IL‑1 beta secretion in LPS-activated human peripheral blood mononuclear cells (PBMC) in a dose-dependent manner (orange line), as measured by the Human IL‑1 beta /IL‑1F2 Quantikine ELISA Kit (Catalog # DLB50). IL‑1 beta secretion inhibited by Recombinant Human IL‑10 (0.25 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL‑10 R beta Monoclonal Antibody (Catalog # MAB874). The ND50 is typically 0.5-2 µg/mL in the presence of LPS (0.25 ng/mL).

Background: IL-10 R beta
IL-10 R beta, also known as IL-10 R2, mediates its biological activities via binding to a heteromeric receptor complex consisting of two distinct type II cytokine receptor subunits, the ligand binding IL-10 R alpha and the IL-10 R beta which does not bind IL-10 by itself but is required for signal transduction. The cDNA for human IL-10 R beta encodes a 325 amino acid (aa) type I transmembrane precursor protein with a 20 aa signal sequence, a 200 aa extracellular region, a 29 aa transmembrane segment and a 76 aa cytoplasmic domain. Within the extracellular region, there are two 100 aa subdomains that resemble the constant region of immunoglobulins. This structural motif is responsible for the alternative designation of IL-10 R beta as CRF2-4 (the 4th member of the cytokine receptor family class II/2). Human and mouse IL-10 R beta share approximately 69% aa sequence identity. Binding of the non-covalent IL-10 dimer to two IL-10 R alpha chains recruits two IL‑10 R beta chains resulting in the activation and phosphorylation of the signaling cascade involving JAK1, TYK2, and STAT3. IL-10 R beta is expressed ubiquitously. IL‑10 R beta is also a component of the IL-22 receptor complex consisting of the IL-10 R beta chain and IL-22 R, another type II cytokine receptor family member.
