详细描述:
Recombinant Human Interleukin-10 (rHu IL-10), originally known as Cytokine Synthesis Inhibitory Factor (CSIF), is an 18.6 kDa protein of 161 amino acid residues that shares over 80% sequence homology with the Epstein-Barr Virus protein BCRFI. The reported biological activities of rHu IL-10, which may be interrelated, include inhibition of macrophage-mediated cytokine synthesis, suppression of the delayed-type hypersensitivity response, and stimulation of the TH2 cell response, which results in elevated antibody production. IL-10 is a cytokine produced primarily by monocytes and to a lesser extent by lymphocytes. This cytokine has pleiotropic effects in immunoregulation and inflammation. It down-regulates the expression of Th1 cytokines, MHC class II Ags, 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. Knockout studies in mice suggested the function of this cytokine as an essential immunoregulator in the intestinal tract. Recombinant human IL-10 produced in HEK cells is a glycosylated non-disulfide bonded homodimer, having a total molecular weight of 17 kDa. It has been purified by proprietary chromatographic techniques.
