NCIt 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. (NCI04);
