摘要

The consumption of stinky tofu, a traditional fermented soybean product from China, elevates the concentrations of indole and trimethylindole in murine feces and increases the levels of indole in serum, as well as indole in the liver. These hepatic compounds act as ligands for the Aryl Hydrocarbon Receptor (AHR), triggering activation of this receptor, which subsequently enhances the expression of the enzyme cytochrome P450 (CYP) 1A1. This upregulation diminishes the levels of pro-inflammatory cytokines, thereby attenuating alcohol-induced liver injury. This study underscores the potential of dietary indole from stinky tofu to mitigate Alcoholic liver disease (ALD), laying a foundation for the development of functional foods and novel treatment strategies for ALD.
