Similar to other T cells, regulatory T cells develop in the thymus. The latest research suggests that regulatory T cells are defined by expression of the forkhead family transcription factor FOXP3 (forkhead box p3). Expression of FOXP3 is required for regulatory T cell development and appears to control a genetic program specifying this cell's fate. The large majority of Foxp3-expressing regulatory T cells are found within the major histocompatibility complex (MHC) class II restricted WebOct 5, 2015 · Control of peripheral tolerance by regulatory T cell–intrinsic Notch signaling Louis-Marie Charbonnier, Sen Wang, Peter Georgiev, Esen Sefik & Talal A Chatila Nature Immunology 16 ,...
