Interleukin-1 receptor antagonist (IL-1RA) is a naturally-occurring, inflammatory-inhibitor protein.? It inhibits the activity of IL-1α and IL-1β by competitively blocking their binding to type I and type II receptors.? IL-1RA is produced by corneal epithelial cells, monocytes, neutrophils, macrophages, and fibroblasts.? Therapeutically, IL-1RA may help in the treatment of sepsis, cachexia, rheumatoid arthritis, chronic myelogenous leukemia, asthma, psoriasis, and inflammatory bowel disease.? Recombinant Human IL-1RA is a 17.2 kDa protein consisting of 153 amino acid residues.
