715-Connectome-seq:单突触分辨率高通量神经环路测序方法

from 聊聊Sci

Connectome-seq 是一种新型高通量神经环路制图技术,旨在以单突触分辨率解析复杂的哺乳动物大脑网络。该方法通过腺相关病毒(AAV)将特定的蛋白-RNA复合物植入神经元,利用条形码序列将突触连接转化为可读的遗传信息。研究人员结合了单细胞核测序与单突触体测序,能够同步获取神经元的分子特征、基因表达以及它们之间的物理连接。通过在小鼠桥脑小脑环路中的成功验证,该技术证明了其在识别已知和未知突触联系方面的可靠性与扩展性。这种基于测序的策略克服了传统电子显微镜成像在处理大体积脑组织时的效率瓶颈,为系统性研究不同生物状态下的大脑接线图提供了高效工具。References: Chen D, Isakova A, Wan Z, et al.
