945-中枢神经损伤反应性增强子的调控逻辑与细胞态靶向
from 聊聊Sci
这份研究揭示了哺乳动物中枢神经系统在损伤后的基因调控机制。研究人员通过对小鼠脊髓损伤进行单细胞多组学分析，成功鉴定出数千个具有细胞类型特异性的损伤响应增强子（IRENs）。利用深度学习模型，科学家们解码了这些增强子的序列逻辑，发现它们通过整合通用的刺激响应信号与特定的细胞身份程序来发挥作用。该研究进一步证实，这些编码规则可用于设计精准的基因递送载体，从而定向调控如反应性星形胶质细胞等特定的病理细胞状态。这一成果为开发针对中枢神经系统损伤和疾病的创新型基因疗法提供了理论基础与工具支撑。References:Zamboni M, Martínez-Martín A, Rydholm G, 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.
