Interleukin-15 (IL-15) is a glycoprotein of 14-15 kDa which was originally found in conditioned medium of a Rhesus monkey kidney epithelial cell line, CV-1/EBNA. IL-15 has been shown to be structurally similar to IL-2. IL-15 is mainly synthesized by macrophage/monocytes and other non-lymphoid cells. This cytokine exerts its effects through its binding to a membrane receptor composed of a private a chain (IL-15Ra) associated with the b chain of IL-2R and the common g subunit of different type I cytokine receptors. As expected, IL-2 and IL-15 share several effects such as the activation of NK cells, the induction of CD8+ T cell proliferation and the costimulation of B-cell proliferation and differentiation. However, IL-15 has additional effects, including the induction of T-cell polarization, differentiation of dendritric cells, inhibition of apoptosis of lymphoid cells and activation of polymorphonuclear leucocytes (PMNs). IL-15 synthesis is mainly regulated at a post-transcriptional level, and different stimuli, including LPS and cytokines (IFNg, TNFa) efficiently induce its production and release. IL-15 has a key role in the pathogenesis of inflammatory and malignant diseases. Abnormalities of IL-15 expression have been described in patients with rheumatoid arthritis or inflammatory bowel disease and in diseases associated with the retrovirus HIV and HTLV.
