1177-人脑膜发育的时空图谱研究

这份名为《解码人类脑膜的时空发育》的研究通过单细胞时空转录组学技术，构建了人类妊娠早期至中期脑膜发育的详尽图谱。研究发现脑膜三层结构的发育具有异步性，其中软脑膜最早形成，且各层成纤维细胞展现出独特的屏障相关与代谢分子特征。软脑膜在招募和定位免疫细胞（尤其是巨噬细胞）中发挥关键作用，这一过程主要由 CXCL12-CXCR4 信号通路驱动。此外，研究识别出一种高表达 TREM2 的特定脑膜巨噬细胞亚群，它们通过调节 CCL2 的分泌来影响皮层中 Cajal-Retzius 细胞的发育。该研究不仅揭示了脑膜脉管系统的时空动态，还为理解神经—免疫相互作用以及脑膜相关疾病的治疗提供了重要理论框架。References:* Li Y, Li Z, She Y, et al.
