260-小鼠端脑GABA能神经元分类和空间图谱

23 Nov 2025

Description

这篇文章对哺乳动物脑部端脑中的 GABA能神经元 进行了全面且深入的转录组学和空间分析。研究人员利用大量的单细胞转录组数据,构建了一个分层的细胞类型分类系统(分类、亚类、超类型和集群),涵盖了小鼠端脑所有区域的 GABA能神经元。此外,研究还追踪了这些神经元的发育起源和轨迹,发现细胞类型关系反映了空间位置和胚胎发育起源,并且许多相关细胞类型通过长距离迁移分散在不同脑区。研究结果揭示了空间基因表达梯度,以及皮层和纹状体神经元与隔膜、视前区和苍白球神经元在出生后分化时间上的显著差异,为理解端脑 GABA能回路的组织提供了基础性参考。References: van Velthoven C T J, Gao Y, Kunst M, et al.
