概述
Interleukin-1 receptor antagonist(IL-1RA)is a member of the IL-1 family.IL-1RA is secreted by various types of cells including immune cells,epithelial cells,and adipocytes,and is a natural inhibitor of the pro-inflammatory effect of IL-1β.This protein inhibits the activities of interleukin 1,alpha(IL-1α)and interleukin 1,beta(IL-1β),and modulates a variety of interleukin 1 related immune and inflammatory responses.IL-4 and IL-13 have been shown to amplify the stimulatory effect of IL1-beta on the production of soluble and intracellular forms of IL1-RA.The regulated expression of IL-1RA in various cell types has been shown to be influenced by cytokines.In synovial fibroblasts the synthesis of IL-1RA is markedly enhanced by IL-1,TNF-α,or PDGF.The protein shows 26%amino acid homology to IL-1β and 19%homology to IL-1α.
