Interleukin-10
Pronunciation
Definition 1
One of a group of related proteins made by leukocytes (white blood cells) and other cells in the body. Interleukin-10 is made by activated macrophages and by some T lymphocytes. It reduces inflammation by blocking production of cytokines by immune cells. Interleukin-10 also increases antibody production by plasma cells and helps them live longer. Interleukin-10 made in the laboratory is used as a biological response modifier to boost the immune system. It is a type of cytokine. Also called IL-10. (NCI Dictionary)
Definition 2
Expressed primarily in monocytes and less in lymphocytes by human IL10 Gene, Interleukin-10 is a cytokine with pleiotropic effects in immunoregulation and inflammation. It down-regulates expression of Th1 cytokines, MHC class II antigens, and costimulatory molecules on macrophages. It also enhances B cell survival, proliferation, and antibody production. This cytokine can block NF-kappa B activity, and is involved in the regulation of the JAK-STAT signaling pathway. Studies in mice suggest that this cytokine as an essential immunoregulator in the intestinal tract. (NCI Thesaurus/LocusLink)
Definition 3
Factor that is a coregulator of mast cell growth. It is produced by T-cells and B-cells and shows extensive homology with the Epstein-Barr virus BCRFI gene. (NLM, Medical Subject Headings)
