Interleukin-15 （IL-15） is a protein that in humans is encoded by the IL15 gene. IL-15 is an inflammatory cytokine with structural similarity to Interleukin-2 （IL-2）. Like IL-2, IL-15 binds to and signals through a complex composed of IL-2/IL-15 receptor beta chain （CD122） and the common gamma chain （gamma-C, CD132）. IL-15 is secreted by mononuclear phagocytes （and some other cells） following infection by virus（es）. This cytokine induces the proliferation of natural killer cells, i.e. cells of the innate immune system whose principal role is to kill virally infected cells. IL-15 is constitutively expressed by a large number of cell types and tissues, including monocytes, macrophages, dendritic cells （DC）, keratinocytes, fibroblasts, myocyte and nerve cells. As a pleiotropic cytokine, it plays an important role in innate and adaptive immunity.
