摘要:

脊髓缺血再灌注损伤是一种严重的脊髓损伤,可导致感觉和运动功能障碍。脊髓缺血再灌注损伤常发生在创伤、脊髓和胸腹主动脉手术后,具有不可预测和难以治疗的特点,这给患者、其家人和社会带来了沉重的负担。脊髓缺血再灌注损伤可导致神经元再生能力差和复杂的病理变化,而线粒体吞噬可降解受损的线粒体,并在神经细胞代谢和能量供应中发挥重要的作用。适度的自噬对脊髓缺血再灌注损伤有益,而过度的自噬则可能对脊髓缺血再灌注损伤有害。因此,文章回顾了自噬在脊髓缺血再灌注损伤病理过程中的潜在机制和调节因子,以准确全面地了解自噬在脊髓缺血再灌注损伤中的最新进展,并阐明其潜在的临床应用价值

Abstract: Spinal cord ischemia-reperfusion injury, a severe form of spinal cord damage, can lead to sensory and motor dysfunction. This injury often occurs after traumatic events, spinal cord surgeries, or thoracoabdominal aortic surgeries. The unpredictable nature of this condition, combined with limited treatment options, poses a significant burden on patients, their families, and society. Spinal cord ischemia-reperfusion injury leads to reduced neuronal regenerative capacity and complex pathological processes. In contrast, mitophagy is crucial for degrading damaged mitochondria, thereby supporting neuronal metabolism and energy supply. However, while moderate mitophagy can be beneficial in the context of spinal cord ischemia-reperfusion injury, excessive mitophagy may be detrimental. Therefore, this review aims to investigate the potential mechanisms and regulators of mitophagy involved in the pathological processes of spinal cord ischemia-reperfusion injury. The goal is to provide a comprehensive understanding of recent advancements in mitophagy related to spinal cord ischemia-reperfusion injury and clarify its potential clinical applications.
