TLR4 and metabolic dysfunction-associated steatotic liver disease: Besides that, quercetin can revert gut microbiota imbalance and TLR-4 pathway induction mediated by endotoxemia, and then subsequently inhibit inflammasome response and reticulum stress pathway activation, leading to the blockage of lipid metabolism and gene expression deregulation, which helps to alleviate NAFLD in HFD mice [38].
