AHR and cystic fibrosis: The AHR agonist 2-(1′-H-indole-3′-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE) modulates production of Th1-associated IL-12 and Th17-associated IL-6, IL-22, and transforming growth factor-β (TGF-β) [34], indicating that AHR activation may help normalize CF-related immune dysregulation.
