BACKGROUND

Interleukin-7 (IL-7) was discovered in 1980s. It is one of the members   of IL-2 superfamily. IL-7 is a cytokine that has been known since long   in immunology, mainly regarding its effects on T-cells and B-cells. IL-7 has   been demonstrated to be necessary for both B-cell and T-cell proliferation   and lack of IL-7 causes immature immune cell arrest. IL7 and the hepatocyte   growth factor (HGF) form a heterodimer that functions as a pre-pro-B cell   growth-stimulating factor. IL7 can be produced locally by intestinal   epithelial and epithelial goblet cells and may serve as a regulatory factor   for intestinal mucosal lymphocytes. IL-7 plays in aging may permit   parsimonious preventative or therapeutic solutions for diverse conditions.
