铁死亡与周围神经损伤的关系

Relationship between ferroptosis and peripheral nerve injury

背景:研究已证实铁死亡与多种神经系统疾病的发生机制密切相关,但铁死亡和周围神经损伤后的病理生理机制有待进一步研究和阐明。目的:综述细胞铁死亡在治疗周围神经损伤进程中的相关作用与作用机制。方法:检索CNKI、PubMed等数据库建库至2024年5月期间铁死亡与周围神经系统损伤的相关文献,检索词为“ferroptosis,Peripheral nerve injury,Antioxidant defense system,Schwann cells,Macrophage,Neuroinflammation,Neuropathic pain”和“铁死亡,周围神经损伤,抗氧化防御系统,施万细胞,巨噬细胞,神经炎症,神经性疼痛”,最终纳入60篇文献进行分析。结果与结论:铁死亡的发生与细胞内铁代谢异常、活性氧积累及脂质过氧化密切相关。周围神经损伤后施万细胞和巨噬细胞均发生铁死亡,导致微环境变化,并且进一步诱导神经炎症及神经疼痛等疾病的发生。越来越多的研究表明神经损伤与铁死亡密切相关,抑制铁死亡可以促进周围神经损伤后的组织修复及功能恢复,因此,研究周围神经损伤细胞铁死亡的发生机制及调节有着重要意义。目前对铁死亡与周围神经损伤后的作用和调控研究仍处于起步阶段,需要进行更深入的研究,为促进周围神经损伤后修复提供更多的策略。

BACKGROUND:It has been confirmed that ferroptosis is closely related to the mechanism of various nervous diseases.However,the pathological mechanisms of ferroptosis and peripheral nerve injury need to be further studied and clarified.OBJECTIVE:To review the role and mechanism of ferroptosis in the treatment of peripheral nerve injury.METHODS:The articles related to ferroptosis and nervous system injuries were searched in CNKI and PubMed databases from database inception to May 2024.The keywords were“ferroptosis,peripheral nerve injury,antioxidant defense system,Schwann cells,macrophage,neuroinflammation,neuropathic pain”in Chinese and English,respectively.Sixty eligible articles were finally included for review.RESULTS AND CONCLUSION:The occurrence of ferroptosis is closely related to abnormal intracellular iron metabolism,reactive oxygen species accumulation and lipid peroxidation.Ferroptosis occurs in both Schwann cells and macrophages after peripheral nerve injury,leading to changes in the microenvironment and further inducing diseases such as neuroinflammation and neuropathic pain.Increasing studies have shown that nerve injury is closely related to ferroptosis,and inhibition of ferroptosis can promote tissue repair and functional recovery after peripheral nerve injury.Therefore,it is of great significance to study the mechanism underlying the occurrence and regulation of ferroptosis after peripheral nerve injury.Current research on the role and regulation of ferroptosis after peripheral nerve injury is still in its infancy,and more in-depth studies are needed to provide more strategies to promote repair after peripheral nerve injury.
