摘要
铁死亡是一种铁依赖性的、非凋亡型的程序性细胞死亡方式,其主要特征是铁代谢紊乱导致细胞内铁超载,通过芬顿反应诱导脂质过氧化,激活铁死亡。铁死亡与诸多疾病相关,其中与腹主动脉瘤的关系近来受到关注。腹主动脉瘤是一种以腹主动脉壁结构破坏、不可逆性扩张为主要特征的退行性病变,其发病机制与氧化应激、炎症反应、血管平滑肌细胞丢失及血管钙化有关。铁死亡可能通过上述途径参与腹主动脉瘤的发生。因此,本文对铁死亡和腹主动脉瘤的致病机制进行综述,为腹主动脉瘤的治疗提供新思路和新靶点。
Ferroptosis is an iron-dependent,non-apoptotic programmed cell death characterized by iron metabolism disorder that leads to intracellular iron overload,which induces lipid peroxidation through fenton reaction and activates ferroptosis.Ferroptosis is associated with many diseases,among which the relationship with abdominal aortic aneurysm has come into attention in the last few years.Abdominal aortic aneurysm is a degenerative disease characterized by structural destruction and irreversible dilation of the abdominal aortic wall.Its pathogenesis is related to oxidative stress,inflammation,loss of vascular smooth muscle cells and vascular calcification.Ferroptosis may play a role in the development of abdominal aortic aneurysm through the above pathways.Therefore,this paper reviews the pathogenesis of ferroptosis and abdominal aortic aneurysm,providing a new idea and target for the abdominal aortic aneurysm treatment.
