Scientific Data Images for Equine IL‑1 beta /IL‑1F2 Antibody

Cell Proliferation Induced by IL‑1 beta /IL‑1F2 and Neutral-ization by Equine IL‑1 beta /IL‑1F2 Antibody.

Recombinant Equine IL-1 beta /IL-1F2 induces proliferation in the D10.G4.1 mouse helper T cell line in the presence of concanavalin A (1.25 µg/mL) in a dose-depend-ent manner (orange line), as measured by the Resazurin (Catalog # AR002). Under these conditions, proliferation elicited by IL-1 beta /IL-1F2 is neutralized (green line) by increasing concen-trations of Mouse Anti-Equine IL-1 beta /IL-1F2 Monoclonal Antibody (Catalog # MAB8049). The ND₅₀ is typically 2-10 µg/mL.

Background: IL-1 beta/IL-1F2

IL-1 is a name that designates two pleiotropic cytokines, IL-1 alpha (IL-1F1) and IL-1 beta (IL-1F2), which are the products of distinct genes. IL-1 alpha and IL-1 beta are structurally related polypeptides that share approximately 27% amino acid (aa) identity in equine. Both proteins are produced by a wide variety of cells in response to inflammatory agents, infections, or microbial endotoxins. While IL-1 alpha and IL-1 beta are regulated independently, they bind to the same receptor and exert identical biological effects. IL-1 RI binds directly to IL-1 alpha or IL-1 beta and then associates with IL-1 R accessory protein (IL-1 R3/IL-1 R AcP) to form a high-affinity receptor complex that is competent for signal transduction. IL-1 RII has high affinity for IL-1 beta but functions as a decoy receptor and negative regulator of IL-1 beta activity. IL-1ra functions as a competitive antagonist by preventing IL-1 alpha and IL-1 beta from interacting with IL-1 RI (1-4). The equine IL-1 beta cDNA encodes a 268 aa precursor. A 115 aa propeptide is cleaved intracellularly by the cysteine protease IL-1 beta -converting enzyme (Caspase-1/ICE) to generate the active cytokine (5-7). An alternatively spliced form of equine IL-1 beta has a deletion which encompasses the Caspase-1 cleavage site and potentially results in a membrane-associated form (8). The 17 kDa mature equine IL-1 beta shares 65%-75% aa sequence identity with canine, cotton rat, feline, human, mouse, porcine, rat, and rhesus IL-1 beta.
