【Abstract】:With the increasing incidence rate of nonalcoholic fatty liver disease (NAFLD) in Western developed countries and rich regions of China year by year, the treatment methods for NAFLD have been constantly improved and NAFLD has become a research hotspot. As an important physiological structure of the liver, liver sinus endothelial cells (LSECs) play an important role in the development and progression of NAFLD. This article summarizes the mechanism of action of LSECs in the pathogenesis of NAFLD, which included the following aspects: LSEC capillarization occurs in nonalcoholic fatty liver and promotes steatosis; meanwhile, LSECs contribute to oxidative stress in nonalcoholic steatohepatitis (NASH) and is a major effector of liver inflammation in NASH, thus promoting liver fibrosis; in addition, angiogenesis is highly stimulated and promotes NAFLD-related hepatocellular carcinoma in NAFLD. However, the role of LSECs in NASH-associated liver cirrhosis has not been validated, which needs to be further clarified to provide new ideas and directions for treatment.
【Key words】:non-alcoholic fatty liver disease; liver sinusoidal endothelial cell; pathologic processes
