Core Tip
Core tip: Autophagy is a mechanism involved in cellular homeostasis. In this review the current knowledge on the role of autophagy in non-alcoholic fatty liver disease (NAFLD) is summarised, with emphasis on the current controversy on the lipolytic vs lipogenic function in hepatic lipid metabolism. Furthermore the role of autophagy in the pathophysiology of insulin resistance, hepatocellular injury and fibrogenesis is reviewed to better understand its importance in NAFLD.
