CD8+ T cells responding to intracellular infection give rise to cellular progeny that become terminally differentiated effector cells and self-renewing memory cells. T-bet and Eomesodermin are key transcription factors of cytotoxic lymphocyte lineages. We now show that CD8+ T cells lacking Eomesodermin compete poorly in contributing to the pool of antigen-specific central memory cells. Eomesodermin-deficient CD8+ T cells undergo primary clonal expansion but are defective in long-term survival, populating the bone marrow niche, and re-expanding after re-challenge. The phenotype of Eomesodermin-deficient CD8+ T cells supports the hypothesis that T-bet and Eomesodermin can act redundantly to induce effector functions, but can also act to reciprocally promote terminal differentiation versus self-renewal of antigen-specific memory cells.
