Exosomal novel-miRNA-126 mediates vascular endothelial dysfunction by targeting AhR-NLRP3 pathway in nonalcoholic steatohepatitis.

ABSTRACT: Nonalcoholic steatohepatitis (NASH) is an increasingly prevalent liver disease associated with obesity and its complications. Recent studies have underscored a significant correlation between NASH and an elevated risk of cardiovascular diseases. However, the precise mechanisms of inter-organ communication between the liver and vascular endothelium are not fully understood. In this study, we established a NASH mouse model using a methionine-choline-deficient diet to investigate the role of liver-derived exosomes in modulating vascular endothelial dysfunction during NASH progression. Utilizing both in vivo and in vitro experimental approaches, we observed vascular dysfunction and activation of the NLRP3 inflammasome in NASH mice. Further analyses identified exosomal novel-miRNA-126 as a crit
