Abstract
Aryl hydrocarbon receptor (AhR) activation suppresses immune responses, including allergic sensitization, by increasing the percentage of regulatory (Treg) cells. Furthermore, AhR activation is known to affect thymic precursor T cells. However, the effect of AhR activation on intrathymic CD4(+)CD25(+)Foxp3(+) Treg cells is unknown. Therefore, we investigated the effect of AhR
