The Aryl Hydrocarbon Receptor Is Involved in UVR-Induced Immunosuppression

UVR suppresses the immune system through the induction of regulatory T cells (Tregs). UVR-induced DNA damage has been recognized as the major molecular trigger involved, as reduction of DNA damage by enhanced repair prevents the compromise to the immune system by UVR. Nevertheless, other signaling events may also be involved. The aryl hydrocarbon receptor (AhR) was identified as another target for UVR, as UVR activates the AhR and certain UVR...
