Detection of IL‑1 beta /IL‑1F2 in THP‑1 Human Cell Line.

IL‑1 beta /IL‑1F2 was detected in immersion fixed THP‑1 human acute monocytic leukemia cell line using Goat Anti-Human IL‑1 beta /IL‑1F2 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF201) at 5 µg/ml for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Streptavidin (red; Catalog # NL999) and counterstained with DAPI (blue). Specific staining was localized to the cytoplasm of THP-1 cells treated with 200nM PMA for 24 hours then 10ug/mL LPS for 24 hours.

Detection of Human IL-1 beta/IL-1F2 by Functional

Differences in Functional Profiles between Three Patients with Different Clinical Outcomesgp100 209–2M spots co-spotted with anti-IFN gamma, anti-TNF alpha, anti-IL1b, and anti-IL-6 are shown for three separate patient samples. Patient 10735, who remains free of disease at this writing, displays strong IFN gamma, TNF alpha, IL-1b, and IL-6 secretion. Patients 10710 and 10737 show strong IFN gamma secretion, but weak to no TNF alpha, IL-1b, and IL-6 secretion; both patients experienced disease recurrence soon after these samples were drawn. Note the diffuse pattern of IL-1b and IL-6 capture, which differs from the focal capture of IFN gamma and TNF alpha.

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 21% amino acid (aa) identity in human. 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 human IL-1 beta shares 96% aa sequence identity with rhesus and 67%-78% with canine, cotton rat, equine, feline, mouse, porcine, and rat 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.
