title: Regulatory T cells GATA have it.
abstract: The factors that control regulatory T (Treg) cell homeostasis and function are still being defined. In this issue of Immunity, Wang et al. (2011) demonstrate that the Th2 cell-associated transcription factor GATA-3 helps control Foxp3 expression in Treg cells and is required for their proper functional activity in vivo.
