610-脑发育与神经炎症的空间多组学图谱

from 聊聊Sci

这项研究介绍并应用了DBiT等先进的空间多组学技术,旨在通过小鼠和人类的大脑样本,同步解析基因组、转录组和蛋白质组的复杂相互作用。研究人员详细绘制了哺乳动物大脑发育过程中的时空动态,揭示了皮层神经元的成熟规律以及胼胝体中协同发生的双向骨髓化进程。此外,该研究利用脱髓鞘病理模型,识别出在受损区域和远端白质中表现各异的免疫细胞状态及炎症演变过程。通过整合空间表观遗传学与基因表达数据,作者发现了基因在发育后期仍保留着早期的转化记忆。这些成果为理解中枢神经系统的精细结构、发育程序以及神经炎症的分子机制提供了全面的多维视图。References: Zhang D, Rubio Rodríguez-Kirby L A, Lin Y, et al.
