Recombinant Interleukin-1-beta

**Semantic type:** Chemical Viewed Functionally

**Definition:** A recombinant therapeutic agent which is chemically identical to or similar to the endogenous protein cytokine interleukin 1 (IL-1)-beta. Produced by monocytes and activated macrophages, endogenous mature IL-1 is generated through proteolytic cleavage by proteases such as IL-1-beta converting enzyme (ICE). This agent promotes angiogenesis, fibroblast proliferation, and neutrophil chemotaxis; it also regulates the functions of lymphocytes and epithelial cells and is involved in the 'acute phase response' to infection.
