General description
Interleukin-10 gene with five exons is mapped to human chromosome 1. The gene codes for 35 kD protein containing 178 amino acids. IL-10 is a homodimer with two, non-covalently bonded monomers.
Application
Interleukin-10 human has been used to study its effect on activation of endogenous signal transducer and activator of transcription 1 (STAT1)/STAT3 in the knock-in, in A549 human lung adenocarcinoma cell line.
Biochem/physiol Actions
IL-10 is an important regulator of the functions of lymphoid and myeloid cells. IL-10 can block the activation of cytokine synthesis and several accessory functions of macrophages. Human and mouse IL-10 share a 73% sequence homology. However, human IL-10 acts on both human and mouse target cells, while mouse IL-10 has species-specific activity. In mouse, the cellular sources of IL-10 consist of Th2 cells, activated fetal thymocytes, macrophages, keratinocytes, LY-1+ (CD5+), and normal B cells. In human, the cellular sources of IL-10 consist of CD4+ T cells and T cell clones, thymocytes, B cells, B cell lymphomas, macrophages, mast cell lines and keratinocytes. IL-10 stimulates the growth of stem cells, mast cells and thymocytes. IL-10 enhances cytotoxic T cell development, and co-stimulates B cell differentiation and Ig secretion. IL-10 regulates angiogenesis by inducing the cell-type dependent expression of either angiogenic or angiostatic factors.

Physical form
Lyophilized from a 0.2 μm filtered solution of 10mM Tris-HCl pH 7.4 + 150mM NaCl
Preparation Note
HumanKine Interleukin-10 (IL-10) is expressed in human HEK 293 cells as a glycosylated, non-disulfide linked homodimer with an apparent molecular mass of 17 kDa due to glycosylation. Glycosylation contributes to stability in cell growth media and other applications.
Analysis Note
The specific activity was determined by the dose-dependent stimulation of the proliferation of MC/9 cells (mouse master cell line) in presence of 200 pg/mL IL-4.

Interleukin (IL)-10 is the most important cytokine with anti-inflammatory properties besides TGF-β and IL-35. It is produced by activated immune cells, in particular monocytes/macrophages and T cell subsets including Tr1, Treg, and Th1 cells. IL-10 acts through a transmembrane receptor
