Regulatory T (TReg) cells are crucial for immune homeostasis, and manipulation of their suppressive functions is a possible avenue for immunotherapy. Here, the authors discuss recent advances in our understanding of how the expression of forkhead box P3 (FOXP3), a TReg-cell-specifying transcription factor, is controlled at the molecular level.
