Interleukin-2 (IL-2) provides a memory differentiation signal to CD8+ T cells during the primary response that impacts the ability of the subsequent memory pool to mount a successful recall response. We find here that while primary effector CTL development is modestly decreased in the absence of IL-2, the persistence of short-term and long-term effector memory CD8+ T cells upon pathogen clearance is greatly diminished. Furthermore, secondary challenge of CD8+ memory T cells lacking the high avidity IL-2 receptor results in a failure to repopulate the effector pool. The role of IL-2 in promoting effector differentiation is not shared with the highly related cytokine, IL-15. While IL-15 supports the survival of effector CD8+ T cells following pathogen clearance, its absence does not impair either primary or secondary effector CTL differentiation, nor does it impact the differentiation of long-term effector memory CD8+ T cells. These findings indicate a unique role for IL-2, but not IL-15, in promoting the differentiation not only of primary effector CD8+ T cells but also of CD8+ memory T cells capable of secondary effector differentiation.
