Abstract:

Garlic is a popular culinary herb for prevention and treatment of alcoholic liver disease (ALD). Diallyl Trisulfide (DATS) is the major organosulfur compound of garlic. Latest studies indicated that the hepatocyte pyroptosis serves a primary role in the pathogenesis of ALD. The present study aims to assess the inhibitory effect of DATS on alcohol-induced hepatocyte pyroptosis, and to elucidate the potential mechanism by using the hepatocyte cell line HL-7702. Our study found that DATS inhibited alcohol-induced pyroptosis by decreasing gasdermin D (GSDMD) activation. Results illuminated that DATS inhibited alcohol induced (NOD)-like receptor containing pyrin domain 3 (NLRP3) inflammasome activation by reducing intracellular reactive oxygen species (ROS) accumulation. Furthermore, DATS upregulated hydrogen sulfide (H2S) to resist ROS overproduction. The present study demonstrated that DATS mitigated alcohol-induced hepatocyte pyroptosis by increasing the intracellular level of H2S.
