Description: Mouse IL-15 is a 14-15 kDa factor, previously known as IL-T. IL-15 is produced by a variety of cells and has a role in the T cell-mediated immune response and the central nervous system. IL-15 binds to the β and γ subunits of the IL-2 receptor; however, these two cytokines have distinct biological activities. IL-15 is a specific maturation factor for NK cells and mimics the BM microenvironment for NK cell development in vitro. It is reported that IL-15 delivers an anti-apoptotic and survival signal for NK, T, and B cells.
