CD4(+)CD25(+)Foxp3(+) regulatory T (T(reg)) cells inhibit autoimmunity and protect against tissue injury. The development of these T(reg) cells is controlled by the regulator protein Foxp3, which can be enhanced by the in vitro activation of Foxp3 in the presence of transforming growth factor-beta. However, little is known about alternative methods, such as the use of natural product...
