Self-reactive T cells that escape negative selection in the thymus must be kept under control in the periphery. Intrinsic functional inactivation and mechanisms of dominant tolerance mediated by regulatory T cells exist to keep self-reactive T cells in check. Both systems are regulated by the activation of specific programmes of gene expression. Suboptimal stimulation of T cells results in the activation of a calcium-/nuclear factor of activated T cells (NFAT)-dependent cell-intrinsic programme of inactivation that, among other consequences, induces epigenetic changes in the interleukin (IL)-2 promoter that silence IL-2 expression and make T cells hypo-responsive to subsequent stimulation. Foxp3 directs the expression of set of genes that specify regulatory T cell development. In regulatory T cells, Foxp3 mediates activation and suppression of transcription of target genes by recruiting a multi-subunit complex involved in histone modification and chromatin remodelling.
