摘要: 铁死亡是一种新型的细胞死亡方式,以细胞内铁过载和脂质代谢紊乱为特征,与心脑血管疾病、肿瘤、急性损伤的发生密切相关。机体组织器官处于缺血缺氧状态下,铁离子启动脂质过氧化反应,产生大量氧自由基,一系列氧化应激反应更容易触发铁死亡。而在椎动脉型颈椎病发生过程中,颈椎退行性改变造成的椎动脉供血不足导致铁稳态失衡、氨基酸代谢异常,诱发的铁死亡对病情发展有重要影响。本文就铁死亡在椎动脉型颈椎病发生中的作用机制展开综述,以期为本病相关问题研究提供新的思路与视角。

Abstract:

Ferroptosis is a novel type of cell death, characterized by iron overload and lipid metabolism disorders, and is closely related to the occurrence of cardiovascular and cerebrovascular diseases, tumors, and acute injuries. When tissues and organs of the body are in a state of ischemia and hypoxia, iron ions initiate lipid peroxidation and produce a large number of oxygen free radicals. A series of oxidative stress reactions are more likely to trigger ferroptosis. In the process of cervical spondylosis of vertebral artery type, insufficient blood supply to the vertebral artery caused by degenerative changes of the cervical spine leads to imbalance of iron homeostasis and abnormal amino acid metabolism. Then ferroptosis is induced and plays an important role in the development of cervical spondylosis of vertebral artery type. This paper reviewed the mechanism of ferroptosis in the occurrence of cervical spondylosis of vertebral artery type, in order to provide new ideas and perspectives for the study of related problems of the disease.

Key words: cervical spondylosis of vertebral artery type, ferroptosis, lipid peroxidation, iron homeostasis, pathomechanisms
