We studies the molecular mechanisms by investigating the roles of Thioredoxin-interacting protein (TXNIP) and NLRP3 on NAFLD development in patients, high-fat diet (HFD)-induced NAFL and methionine choline deficient (MCD) diet-induced NASH in wild type (WT), TXNIP−/− (thioredoxin-interacting protein) and NLRP3−/− mice, and isolated KCs. The gene discussed is NLRP3; the disease is metabolic dysfunction-associated steatohepatitis.
