1231-老鼠大脑神经与神经胶质细胞代谢图谱研究
from 聊聊Sci
该研究系统地描绘了小鼠大脑中神经元、星形胶质细胞和小胶质细胞的代谢图谱，并建立了一个综合性的代谢数据库。研究团队通过开发高效的细胞纯化技术，利用针对性和非针对性代谢组学识别出了数千种代谢特征，揭示了不同细胞类型特有的代谢通路。研究特别强调了小胶质细胞中谷胱甘肽（GSH）和多胺代谢的富集，并发现这些代谢途径与趋化因子基因表达密切相关。此外，该文献还深入探讨了这些细胞代谢物在衰老过程和阿尔茨海默病模型中的动态变化，指出代谢失衡可能是神经退行性疾病的关键诱因。这项工作为理解脑细胞生理功能及其在病理状态下的代谢网络崩溃提供了重要的资源支持。References:Yu J, Li F, Chen X, 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.
