Human Interleukin 7 (IL-7) activity is important for every stage of T cell development and survival of naïve T cells and generation and maintenance of CD4 and CD8 T cell memory. It is also important for the formation of lymphoid structure and defense mechanisms mediated by lymphoid cells. Pathologies associated with IL-7 are those mediated by the dysregulation of lymphoid function leading to autoimmune diseases such as diabetes and multiple sclerosis, (1) and chronic inflammatory diseases, including rheumatoid arthritis and inflammatory bowel disease (2). IL-7 signaling is also associated with several types of lymphoid leukemias (3). IL-7 is a glycosylated 25 kDa hematopoietic growth factor that plays a central regulatory role throughout the lymphoid system (3).
