CD4 expression in effector T cells depends on DNA demethylation over a developmentally established stimulus-responsive element
Abstract
Epigenetic states that are established during thymic T cell development influence functionality of mature T cells. Authors here show that early developmental programming of the Cd4 locus is comprised of DNA-demethylation at a specific stimulus-responsive element, which allows long-term maintenance of activator histone H3K4 trimethylation and transcription.
