Scientific Data

Western Blot Detection of Mouse IL-1 beta /IL-1F2 antibody by Western Blot. View Larger

Detection of Mouse IL‑1 beta /IL‑1F2 by Western Blot. Western blot shows lysates of RAW 264.7 mouse monocyte/macrophage cell line untreated (-) or treated (+) with LPS. PVDF membrane was probed with 1 µg/mL of Rat Anti-Mouse IL-1 beta /IL-1F2 Monoclonal Antibody (Catalog # MAB4011) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for IL-1 beta /IL-1F2 at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Mouse IL-1 beta/IL-1F2 by Western Blot Pleural cells are involved in bleomycin-induced inflammation. a Cell recruitment in PLF was assessed by total cell count at D3, D14 and D21. Results are expressed as mean ± SEM. b Inflammation was estimated by differential count in PLF after May-Grünwald Giemsa staining. Results are expressed as percentages of total cells. n = 4 for NaCl groups, n = 6 for BLM groups at D3 and D21, n = 6 for NaCl and n = 8 for BLM at D14. c, d Caspase-1 activation was assessed at D14 by c western blot in whole lung extracts (n = 3 mice/group) or by d specific caspase-1 FLICA analysis on lung section from NaCl or BLM injected mice (Representative images are shown. Active caspase-1: green, DAPI: blue, dotted lines represent the pleura, scale bars: 50 μm). e, f Met5A cells were treated with BLM (100 μM) and e activation of caspase-1 was followed (western blot; left, densitometric analysis; right). f active IL-1 beta was assessed in the supernatant of Met5A cells after 24 h of culture. Representative results from 3 independent experiments.

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, IL1B), which are the products of distinct genes. IL-1 alpha and IL-1 beta are structurally related polypeptides that share approximately 17% amino acid (aa) identity in mouse. 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. Intracellular cleavage of the IL-1 beta precursor by Caspase-1/ICE is a key step in the inflammatory response. The 17 kDa molecular weight mature mouse IL-1 beta shares 90% aa sequence identity with cotton rat and rat and 67%-78% with canine, equine, feline, human, porcine, and rhesus macaque IL-1 beta. IL-1 beta functions in a central role in immune and inflammatory responses, bone remodeling, fever, carbohydrate metabolism, and GH/IGF-I physiology. IL-1 beta dysregulation is implicated in many pathological conditions including sepsis, rheumatoid arthritis, inflammatory bowel disease, acute and chronic myelogenous leukemia, insulin-dependent diabetes mellitus, atherosclerosis, neuronal injury, and aging-related diseases.
