NAT IMMUNOL:神经炎症中氧化应激的转录谱分析和治疗靶点研究

2020-04-15 MedSci MedSci原创

最近,研究人员提供了神经炎症性疾病中的氧化应激先天免疫细胞图谱,并报告了新的可成药途径的发现。

氧化应激是先天性免疫诱导的神经变性的一个核心部分。然而,至今为止,中枢神经系统(CNS)先天性免疫细胞的转录组图谱是未知的,而针对其神经毒性功能的治疗方法还没有被广泛使用。

最近,研究人员提供了神经炎症性疾病中的氧化应激先天免疫细胞图谱,并报告了新的可成药途径的发现。

氧化应激产生的中枢神经系统先天性免疫细胞的转录谱分析确定了一个核心氧化应激基因特征,其中凝血和谷胱甘肽通路基因在小胶质细胞群和浸润性巨噬细胞之间共享。

利用Tox-seq,以及随后的小胶质细胞高通量筛选和氧化应激基因网络分析,研究人员找到了谷胱甘肽调控化合物阿西维辛,其具有降低慢性和复发性多发性硬化症模型中的氧化应激和轴突损伤的有效治疗作用。

因此,氧化应激转录组学发现了具有神经毒性的中枢神经系统先天性免疫群体,并可能使选择性神经保护策略的发现成为可能。
