Raf signaling but not the ERK effector SAP-1 is required for regulatory T cell development. (ox.ac.uk)
Their development in the thymus requires TCR activation and recognition of peptide-MHC, although the downstream signals controlling commitment to the lineage are unclear. (ox.ac.uk)

The conventional wisdom then, and until a few years ago was that, because T cells are highly specific (they only recognize one antigen among the millions possible), they would remain quiescent until they saw their precise antigen and would be driven through the cell cycle by pathways that regulate the cell cycle machinery.
