Abstract
IL-15 is a pleiotropic cytokine that plays an important role in both the innate and adaptive immune system. IL-15 promotes the activation of neutrophils and macrophages, and is critical to DC function. In addition, IL-15 is essential to the development, homeostasis, function and survival of natural killer (NK) cells, NK T (NKT) cells and CD8+ T cells. Based on these properties, IL-15 has been proposed as a useful cytokine for immunotherapy. It is currently being investigated in settings of immune deficiency, for the in vitro expansion of T and NK cells, as well as an adjuvant for vaccines. In this paper, we will review the targeting of IL-15 for immunotherapy, with a particular emphasis on its effects on CD8+ T cells.
