A new study demonstrates that commitment to the CD8 lineage in the thymus requires sequential T cell antigen receptor (TCR) and interleukin 7 (IL-7) signaling. The TCR signal first induces IL-7 responsiveness, then recognition of IL-7 induces the nuclear factor Runx3, which specifies the CD8 lineage.
