Parkinsons disease (PD) is a fatal and progressive degenerative disease of the nervous system. Until recently, its promising treatment and underlying mechanisms for neuronal death are poorly understood. This study was investigated to identify the molecular mechanism of neuronal death in the substantia nigra and corpus striatum of PD.
The soluble RAGE (sRAGE) secreting Umbilical Cord Blood-derived Mesenchymal Stem Cell (UCB-MSC) was generated by gene editing method using clustered regularly interspaced short palindromic repeats/CRISPR associated protein 9 (CRISPR/Cas9). These cells were transplanted into Corpus Striatum of rotenone-induced PD animal models then behavioral test, morphological analysis, and immunohistochemical experiments were performed to determine the neuronal cell death and recovery of movement.
The neuronal cell death in Corpus Striatum and Substantia Nigra was dramatically reduced and the movement was improved after sRAGE secreting UCB-MSC treatment in PD mice by inhibition of RAGE in neuronal cells.
We suggest that sRAGE secreting UCB-MSC based therapeutic approach could be a potential treatment strategy for neurodegenerative disease including PD.
帕金森病(PD)是一种致命的进行性神经系统退行性疾病。直到最近,其有前景的治疗方法及神经元死亡的潜在机制仍知之甚少。本研究旨在确定帕金森病黑质和纹状体中神经元死亡的分子机制。
使用成簇规律间隔短回文重复序列/CRISPR相关蛋白9(CRISPR/Cas9)基因编辑方法生成分泌可溶性晚期糖基化终末产物受体(sRAGE)的脐带血间充质干细胞(UCB-MSC)。将这些细胞移植到鱼藤酮诱导的帕金森病动物模型的纹状体中,然后进行行为测试、形态学分析和免疫组织化学实验,以确定神经元细胞死亡和运动恢复情况。
在帕金森病小鼠中,通过抑制神经元细胞中的晚期糖基化终末产物受体(RAGE),分泌sRAGE的UCB-MSC治疗后,纹状体和黑质中的神经元细胞死亡显著减少,运动功能得到改善。
我们认为,基于分泌sRAGE的UCB-MSC的治疗方法可能是包括帕金森病在内的神经退行性疾病的潜在治疗策略。
