998-中枢神经系统髓系细胞发育与迁徙门控研究
from 聊聊Sci
这篇综述深入探讨了中枢神经系统（CNS）中髓系免疫细胞的来源、分类及其进入大脑的解剖路径。研究指出，健康的神经系统中主要存在由胚胎发育早期形成的小胶质细胞和中枢相关巨噬细胞（CAMs）。虽然成人脑部通常限制外部免疫细胞进入，但在胚胎发育、自然衰老或病理状态下，特定的“门户”结构会允许血液循环中的单核细胞浸润。文章详细对比了软脑膜、血管周围空间及脉络丛等不同区域巨噬细胞的替换机制。理解这些分子信号和解剖屏障的动态变化，对于开发针对神经系统疾病的细胞疗法具有重要意义。References:Amann L, Prinz M.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
