Interleukin­2 (IL-2), otherwise known as T­cell growth factor, is a multi­functional immunoregulatory cytokine and member of the IL-2 family, secreted by antigen or mitogen stimulated T cells. IL-2 signals through the IL-2 receptor complex (IL­2R), and is principally involved in the stimulation of the T cell proliferative response, promoting T cell clonal expansion and the expansion of T memory cells expressing low levels of high-affinity IL-2R. IL-2 also stimulates the growth/differentiation of B cells, monocytes, NK cells, macrophages and lymphokine activated killer cells.
