Scurfy mice have a deletion in the forkhead domain of Foxp3, fail to develop thymic-derived Foxp3+ regulatory T cells (nTreg), and develop a fatal lymphoproliferative syndrome with multi-organ inflammation. Transfer of thymic-derived Foxp3+ nTreg into neonatal Scurfy mice prevents the development of disease. Stimulation of conventional CD4+Foxp3− via the TCR in the presence of TGFβ and IL-2 induces the expression of Foxp3 and an anergic/suppressive phenotype. To determine whether the TGFβ-induced Treg (iTR) were capable of suppressing disease in the Scurfy mouse, we reconstituted newborn Scurfy mice with polyclonal iTR. iTR-treated Scurfy mice do not show any signs of disease and have drastically reduced cell numbers in peripheral lymph nodes and spleen in comparison to untreated Scurfy controls. The iTR retained their expression of FoxP3 in vivo for 21 days, migrated into the skin, and prevented the development of inflammation in skin, liver and lung. Thus, TGFβ-differentiated Foxp3+ Treg appear to possess all of the functional properties of thymic-derived nTreg and represent a potent population for the cellular immunotherapy of autoimmune and inflammatory diseases.
