title: Cytokines: shared receptors, distinct functions.
abstract: That the signal transduction pathways used by the cytokines IL-2 and IL-15 are identical would suggest that these cytokines have redundant roles in lymphoid development; instead, IL-2 is the guardian of thymus-derived T-cell homeostasis, while interleukin-15 promotes extrathymic development of T and NK cells.
