摘要 脊髓损伤(SCI)的过程中伴随着大量少突胶质细胞(OLs)的死亡,而OLs的死亡直接导致有髓神经纤维失去正常的电传导作用,引起脊髓的上下传导功能减弱甚至丧失,最终导致机体的感觉及运动功能损伤。因此本综述归纳了SCI后影响OLs死亡的各种微环境,并简述了OLs再生和髓鞘再生在SCI修复中的重要作用。最后针对影响OLs死亡和再生的各种因素,对SCI的治疗方式进行了分类总结,并对OLs在SCI治疗中的应用前景作了展望。 Spinal cord injury （SCI） is frequently eompanied by necrosis and apoptosis of oligodendrocytes（OLs）, which contributes to demyelination of myelinated nerve fibers and their electrophysiological defects. This pathological demyelination often results in sensory or motor deficits. Here, we first focus on the mieroenvironment changes after SCI that cause OLs＇ death, then discuss the major mechanism of endogenous oligodendrocytogenesis and axonal remyelination, and finally summarize current therapies targeting OLs protection and replacement.
