Human IL-1 beta ELISA kit is intended for detecting in vitro quantitative concentrations of interleukin-1 beta (IL-1 beta, IL-1β, IL-1b) present in human tissue homogenates, serum, plasma (citrate, EDTA, heparin) other biological fluids. This assay has a minimum detection limit of 2.344 pg/ml.
Interleukin-1 beta (IL-1 beta, IL-1β or IL-1b) has been strongly implicated in the pathogenesis of osteoporosis and high bone turnover, it is a potent stimulator of bone resorption. Early researchers even called IL-1 beta endogenous pyrogen since it was able to induce fever and contributed to the wasting of muscles (PIF or proteolysis inducing factor). Low levels of IL-1 beta have been reported in normal serum and IL-1 inhibitors that vary only in their degree of glycosylation have been described to bind to the IL-1 receptor. These inhibitors are structurally more similar to IL-1 beta and have been thought to play vital roles in regulating the action of IL-1 beta.
The cells that are known to express IL-1b include endothelial cells, natural killer (NK) cells, trophoblasts, astrocytes, osteoblasts, keratinocytes, adrenal cortical cells, Schwann cells, neutrophils, oligodendroglia, T cells plus fibroblasts, monocytes and macrophages, platelets and megakaryocytes. Interleukin-1β can cause nuclear export of a specific NCOR co-repressor complex, leading to the de-repression of a specific subset of nuclear factor-kappa-B (NFKB)-regulated genes. It is a prominent microglia-derived cytokine which can cause oligodendrocyte death in co-culture with astrocytes and microglia, but not in pure culture of oligodendrocytes by alone.
Furthermore, co-operation of IL-1 beta and PDGFB can result in inducing contractile-to-synthetic phenotype modulation of human aortic smooth muscle cells in culture. Micro-environmental IL-1β is essential for invasiveness and in vivo angiogenesis of different tumor cells. This association with the disease can be used to explain the biologic properties of IL-1 beta, thereby making it an important pro-inflammatory cytokine and a powerful inhibitor of gastric acid secretion.
