CD4+ regulatory T cells expressing the transcription factor Foxp3 can be generated in the thymus (tTreg cells), but the cellular and molecular pathways driving their development remain incompletely understood. Transforming growth factor-beta (TGF-β) is essential for the generation of Foxp3+ Treg cells converted from peripheral naive CD4+ T cells (pTreg cells), yet a role for TGF-β in tTreg-cell development was initially refuted. Nevertheless, recent studies have unmasked a requirement for TGF-β in the generation of tTreg cells. Experimental evidence reveals that TGF-β in the context of TCR stimulation induces Foxp3 gene transcription in thymic Treg precursors, CD4+CD8−CD25− semi-mature and mature single-positive (SP) thymocytes. Intriguingly, thymic apoptosis was found to be intrinsically linked to the generation of tTreg cells, as apoptosis induced expression of TGF-β intra-thymically. In this short review, we will highlight key data, discuss the experimental evidence and propose a modified model of tTreg-cell development involving TGF-β. We will also outline the remaining unresolved questions concerning generation of thymic Foxp3+ Treg cells and provide our personal perspectives on the mechanisms controlling tTreg-cell development.
