487-修复神经胶质：皮肤愈合的免疫调控中枢
from 聊聊Sci
这项研究揭示了外周神经胶质细胞在皮肤伤口愈合早期的关键调节作用。研究发现，受伤后这些细胞会转化为修复型胶质细胞，通过分泌CCL2等趋化因子构建出一个独特的微环境。这一机制能精准招募单核细胞和巨噬细胞，进而诱导成纤维细胞增殖并转化为肌成纤维细胞。实验证明，如果缺失这些胶质细胞或阻断相关的MCP-CCR2信号通路，会导致免疫反应受阻、血管生成减少及伤口闭合延迟。总之，神经系统通过胶质细胞与免疫系统的跨界对话，在空间和时间上协调了皮肤组织的再生修复进程。References: Stierli S, Salas-Bastos A, Micheli S, et al.

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.
