The maintenance of naive CD8(+) T cells is necessary for lifelong immunocompetence but for unknown reasons requires signaling via both interleukin 7 (IL-7) and the T cell antigen receptor (TCR). We now report that naive CD8(+) T cells required IL-7 signaling to be intermittent, not continuous, because prolonged IL-7 signaling induced naive CD8(+) T cells to(More)
Major histocompatibility complex class I (MHC I) positive selection of CD8+ T cells in the thymus requires that T cell antigen receptor (TCR) signaling end in time for cytokines to induce Runx3d, the CD8-lineage transcription factor. We examined the time required for these events and found that the overall duration of positive selection was similar for all(More)
