项目摘要
In this study, We focused on endoplasmic reticulum(ER) stress as a cause of apoptosis of oligodendrocyte precursor cell(OPC) following spinal cord injury, and examined it in vivo, and in vitro. In addition, We investigated the effects of G-CSF and SCF on intrinsic cells, and motor function recovery in spinal cord-injured mice. The results showed that the combined administration of SCF and G-CSF in mouse contusive spinal cord injury model not only improved motor function, but also induced the accumulation of intrinsic microglia and the active proliferation of intrinsic OPC. Our results suggest that apoptosis by the ER stress is involved in the differential inhibition of OPC, and To increase the tolerance of ER stress response of OPC may result in remyelination of damaged spinal cord.
在这项研究中,我们重点关注内质网(ER)应激作为脊髓损伤后少突胶质细胞前体细胞(OPC)凋亡的原因,并在体内和体外进行了检查。此外,我们还研究了 G-CSF 和 SCF 对脊髓损伤小鼠内在细胞和运动功能恢复的影响。结果表明,在小鼠挫伤性脊髓损伤模型中联合给予SCF和G-CSF不仅可以改善运动功能,而且可以诱导内在小胶质细胞的积累和内在OPC的活跃增殖。我们的结果表明,ER应激引起的细胞凋亡参与了OPC的差异性抑制,增加OPC对ER应激反应的耐受性可能导致受损脊髓的髓鞘再生。
