The aryl hydrocarbon receptor (AHR), the receptor for dioxin, has been known to cause immunosuppression after binding dioxin. It has recently been discovered that the receptor may be central to T cell differentiation into FoxP3+ T regulatory cells vs. TH17 cells. In this paper we demonstrate that kynurenine, the first breakdown product in the indoleamine 2,3-dioxygenase(IDO)-dependent tryptophan degradation pathway, activates the AHR. We furthermore show that this activation leads to AHR-dependent T regulatory cell generation. We additionally investigate the dependence of TGF-β on the AHR for optimal Treg generation, which may be secondary to the upregulation of this receptor that is seen in T cells after exposure to TGF-β. These results shed light on the relationship of IDO to the generation of regulatory T cells, in addition to highlighting the central importance of the AHR in T cell differentiation. All tissues and cells were derived from mice.
