摘要
铁死亡是近年提出的一种新型细胞死亡方式,其主要特征为铁过载及脂质过氧化。铁死亡参与非酒精性脂肪性肝病的发生发展。铁过载可通过芬顿反应产生大量活性氧,在脂氧合酶的作用下,肝细胞膜上的不饱和脂肪酸发生脂质过氧化,从而诱导肝细胞死亡,导致非酒精性脂肪性肝病/非酒精性脂肪性肝炎的发生。阻断铁死亡可能成为保护肝细胞的治疗策略之一。
Ferroptosis is a new type of cell death proposed in recent years,and its main characteristics are iron overload and lipid peroxidation.Ferroptosis is involved in the occurrence and development of non-alcoholic fatty liver disease(NAFLD).Iron overload can generate a large amount of reactive oxygen species through the Fenton reaction.Under the action of lipoxygenase,the unsaturated fatty acids on the liver cell membrane undergo lipid peroxidation,which induces liver cell death and leads to the occurrence of non-alcoholic fatty liver disease/non-alcoholic steatohepatitis.Blocking ferroptosis may provide one of the therapeutic strategies to protect liver cells.
