Functional CD8+ T‐cell populations among acute phase effector cells and memory cells can be distinguished by differences in the expression of IL‐7Rα and KLRG1. Cells with a IL‐7Rαlo/KLRG1hi phenotype, previously defined as short‐lived effector cells in mice, persist long after the acute phase of primary CMV infection in humans.
