Article Title: The transcription factor foxo1 controls central-memory CD8+ T cell responses to infection
Abstract: Memory Tcells protect hosts from pathogen reinfection, but how these cells emerge from a pool of antigen-experienced Tcells is unclear. Here, we show that mice lacking the transcription factor Foxo1 in activated CD8+ Tcells have defective secondary, but not primary, responses to Listeria monocytogenes infection. Compared to short-lived effector Tcells, memory-precursor Tcells expressed higher amounts of Foxo1, which promoted their generation and maintenance. Chromatin immunoprecipitation sequencing revealed the transcription factor Tcf7 and the chemokine receptor Ccr7 as Foxo1-bound target genes, which have critical functions in central-memory Tcell differentiation and trafficking. These findings demonstrate that Foxo1 is selectively incorporated into the genetic program that regulates memory CD8+ Tcell responses to infection. © 2013 Elsevier Inc.
