摘要:

脊髓损伤是一种由创伤引起的神经系统疾病,常会影响损伤部位的感觉和运动功能,甚至导致瘫痪和内部功能障碍。目前,脊髓损伤的治疗主要依赖于药物和手术,但两者对于保护和修复神经组织仍存在挑战。自噬是一种细胞内大分子成分降解和再循环的过程,在脊髓损伤中起着至关重要的作用。自噬可通过抑制细胞凋亡和炎症反应来减轻脊髓损伤的严重程度。此次综述概述了自噬和脊髓损伤的生理过程,还描述了脊髓损伤中自噬和其他细胞死亡模式的串扰。此外,还讨论了如何将自噬用作治疗SCI的潜在策略,包括促进或抑制自噬、靶向特定的自噬底物或通路,以及与其他神经保护或恢复方法相结合。文章提出可通过严格调节自噬水平和选择性治疗脊髓损伤。

Abstract: Spinal cord injury is a neurological disorder resulting from trauma, typically affecting sensory and motor function at the injury site, even leading to paralysis and internal dysfunction. The treatment of spinal cord injury mainly relies on pharmacological and surgical interventions; however, significant challenges remain in the protection and repair of neural tissues. Autophagy, an intracellular process responsible for the degradation and recycling of macromolecular components, plays a vital role in spinal cord injury, alleviating the severity of injury by inhibiting cell apoptosis and inflammatory responses. In this review, we provide an overview of the physiological mechanisms underlying autophagy and spinal cord injury and detail the crosstalk between autophagy and other modes of cell death in spinal cord injury. In addition, we discuss the potential of targeting autophagy as a therapeutic strategy for spinal cord injury through approaches that focus on promoting or inhibiting this process, targeting specific autophagic substrates or pathways, and combining autophagy modulation with other neuroprotective or restorative interventions. In summary, this review proposes that strict regulation of autophagy may represent a viable strategy for the treatment of spinal cord injury.
