IL-1 RI Antibody [Unconjugated]

IL‑1 RI was detected in perfusion fixed frozen sections of mouse skin (tail) using Goat Anti-Mouse IL‑1 RI Antigen Affinity-purified Polyclonal Antibody (Catalog # AF771) at 1 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to developing central nervous system.

Recombinant Mouse IL‑1 alpha /IL‑1F1 (Catalog # 400-ML) stimulates proliferation in the the D10.G4.1 mouse helper T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse IL‑1 alpha /IL‑1F1 (50 pg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse IL‑1 RI Antigen Affinity-purified Polyclonal Antibody (Catalog # AF771). The ND50 is typically 0.2-1.0 µg/mL in the presence of concanavalin A (1.25 µg/mL).

Background

Two distinct types of receptors that bind the pleiotropic cytokines IL-1 alpha and IL-1 beta have been described. The IL-1 receptor Type I is an 80 kDa transmembrane protein that is expressed predominantly by T cells, fibroblasts, and endothelial cells. IL-1 receptor Type II is a 68 kDa transmembrane protein found on B lymphocytes, neutrophils, monocytes, large granular leukocytes and endothelial cells. Both receptors are members of the immunoglobulin superfamily and show approximately 28% sequence identity in their extracellular domains. The two receptor types do not heterodimerize into a receptor complex. Mouse IL-1 RI shares 63% amino acid sequence homology with human IL-1 RI in their extracellular domains.

An IL-1 receptor accessory protein (1) that can heterodimerize with the Type I receptor in the presence of IL-1 alpha or IL-1 beta  but not IL-1ra, was identified. This Type I receptor complex appears to mediate all the known IL-1 biological responses. The receptor Type II has a short cytoplasmic domain and does not transduce IL-1 signals. In addition to the membrane-bound form of IL-1 RII, a naturally-occurring soluble form of IL-1 RII has been described. It has been suggested that the Type II receptor, either as the membrane-bound or as the soluble form, serves as a decoy for IL-1 and inhibits IL-1 action by blocking the binding of IL-1 to the signaling Type I receptor complex. Recombinant IL-1 soluble receptor Type I is a potent antagonist of IL-1 action.
