Liver injury due to acetaminophen overdose is one of the main causes of acute liver failure,with a complex pathogenesis. In this process,liver sinusoidal endothelial cell (LSEC) injury is a key early event jointly mediated by factors such as oxidative stress,cell apoptosis,and imbalance between fibrinolysis and coagulation. Subsequent LSEC dysfunction further induces sinusoidal microcirculatory disturbances,amplifies the inflammatory response,impairs the regeneration and repair abilities of the liver,and finally causes hepatocyte necrosis. This article systematically elaborates on the critical role and molecular mechanism of LSEC in acetaminophen-induced liver injury,in order to provide a theoretical basis for novel therapeutic strategies and research directions.
