410-胶质细胞线粒体转移与神经保护
from 聊聊Sci
这项研究揭示了背根神经节（DRG）中卫星胶质细胞（SGCs）与感觉神经元之间一种独特的代谢支持机制。研究人员发现，由于感觉神经元的轴突极长，其能量需求面临巨大挑战，而周围的卫星胶质细胞能通过名为隧道纳米管（TNTs）的结构向神经元输送线粒体。通过对人类和小鼠组织的研究，科学家确定了MYO10蛋白质在构建这些输送通道中起着核心作用。在糖尿病或化疗引发的神经病变等病理状态下，这种线粒体转移过程会受损，进而导致神经功能障碍。通过基因手段干预或调节这一转移机制，有望为缓解慢性疼痛和促进神经再生提供全新的治疗策略。References: Xu J, Li Y, Novak C, 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.
