To be or not to be a Treg: Epigenetische Regulation der Foxp3-Expression in regulatorischen T-Zellen

Regulatory T cells (Treg) harbor great therapeutic potential for the treatment of autoimmune diseases due to their potent suppressive capacity. The majority of these cells express the transcription factor Foxp3, which is critical for both development and function of Treg. We discuss here our recent data indicating a contribution of epigenetic regulation for the permanent expression of Foxp3 in stable Treg a finding that is of significant importance if Treg are devised for clinical applications.
