Figure 1 Positive Reinforcement of Foxp3 and TGF-β-Dependent Circuits TGF-β signaling at its heterodimeric receptor (TGF-βRI–TGF-βRII) results in the phosphorylation of the TGF-β-regulated transcriptional activators Smad2 and Smad3 proteins, their association with Smad4, and translocation to the nucleus. Smad-dependent induction of Foxp3 in turn reinforces TGF-β-dependent gene expression, including the transcription of TGF-βRI. A proposed mechanism involves the promotion by Foxp3 of Smad protein retention in the nucleus. Immunity 2007 27, 693-695DOI: (10.1016/j.immuni.2007.11.004) Copyright © 2007 Elsevier Inc.
