Treatment of mice with 2,3,7,8-tetrachlorodibenzo-p-dioxin leads to aryl hydrocarbon receptor-dependent nuclear translocation of NF-kappaB and expression of Fas ligand in thymic stromal cells and consequent apoptosis in T cells.

Abstract excerpt

We investigated the role of aryl hydrocarbon receptor (AhR) in the regulation of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced apoptosis in thymic T cells. AhR knockout (KO) mice were resistant to TCDD-induced thymic atrophy and apoptosis when compared with the AhR wild-type mice. TCDD triggered the expression of several apoptotic genes, including FasL in AhR wild-type but not AhRKO mice. TCDD-induced...
