铁死亡与缺血性脑卒中

扫码查看
铁死亡是一种铁代谢异常、脂质过氧化物累积构成的可调节性新型细胞死亡方式.缺血性脑卒中是全球第二大常见的脑血管疾病,病死率、致残率、复发率极高,其发生伴随着大量神经元死亡.现有研究证明,缺血性脑卒中发病机制与铁死亡关系密切.缺血性脑卒中损伤中出现的细胞内铁水平升高、脂质过氧化物增多和抗氧化能力下降的现象与铁依赖性非凋亡形式的铁死亡相一致.因此,阐明铁死亡在缺血性脑卒中的发生机制,有利于为其临床治疗提供新靶点.本文将从铁代谢、脂质代谢、氨基酸代谢、活性氧生成的调控等方面论述铁死亡发生的调节机制,着重探讨铁死亡发生在缺血性脑卒中的病理生理机制,期望以铁死亡为切入点,为缺血性脑卒中的临床治疗提供参考.
Ferroptosis and ischemic stroke
Ferroptosis is a new and regulated cell death mode composed of abnormal iron metabolism and accumulation of lipid peroxides.Ischemic stroke is the second most common cerebrovascular disease in the world with the highest fatality rate,disability rate and recurrence rate,and its occurrence is accompanied by the death of a large number of neurons.Existing studies have demonstrated that the neuronal pathogenesis of ischemic stroke is similar to ferroptosis.Ischemic stroke damage in intracellular iron levels,increased lipid peroxide and antioxidant capacity decline phenomenon of iron is similar to the iron dependence of apoptosis in the form of death.Therefore,studying the induction mechanism of ferroptosis in ischemic stroke is beneficial to provide new targets for clinical treatment of stroke.This review will discuss the regulatory mechanism of ferroptosis from iron metabolism,lipid metabolism,amino acid metabolism,active oxygen generating system and the relationship between ferroptosis and ischemic stroke,in order to provide an entry point for ischemic stroke by intervening in ferroptosis and provide reference for its clinical treatment.
