Descripción

Descripción general

Interleukin-1β (IL1B) is produced by activated macrophages. It is synthesized as pro-IL-1β which is changed to active form IL-1β with the help of pro-inflammatory protease caspase-1. IL-1β belongs to the IL-1 gene family. It is a proinflammatory cytokine. The gene is mapped to human chromosome 2q14. In comparison with the Escherichia coli expressed protein, IL-1β is 50% more potent in promoting human CD4+ T cell differentiation into Th17 (T helper) cells. This cytokine is produced in a serum free, chemically defined media.

Aplicación

• IL-1β (IL1B) has been used to check the expression of NGAL (neutrophil gelatinase-associated lipocalin) in epithelial cells after stimulation with proinflammatory cytokines.
• It has been used to check anti-inflammatory activities of N-Acetylglucosamine in human chondrocytes.
• It has been used to create inflammatory endothelium in human coronary artery endothelial cells.

Acciones bioquímicas o fisiológicas

IL-1β (IL1B) stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation and fibroblast growth factor activity. IL-1β proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cells. IL-1β is present in chronic inflamed tissues and also in tissues going for fibrogenesis. It brings neutrophil and macrophage to the site of infection. Mutations in IL-1β gene are linked with renal manifestations and renal sequelae in Henoch-Schönlein purpura. It is also associated with destruction of β-cell in type 1 diabetes.
