1320-ALS运动神经元退行性变的疾病关联状态研究
from 聊聊Sci
这项研究通过对ALS小鼠模型进行纵向的多组学分析，揭示了运动神经元退化的分子机制。研究人员发现，原本健康的α-运动神经元在病亡前会转化为一种被称为“疾病相关运动神经元（DM）”的特殊细胞状态。这种状态转变由特定的转录因子网络驱动，并伴随着数千种基因表达和染色体可及性的改变。实验证明，该病理特征在人类ALS患者中同样存在，且与遗传风险位点显著相关。这些发现为理解ALS的细胞选择性易感性提供了新视角，并为开发潜在的治疗干预手段指明了方向。References:Gautier O, Blum J A, Nguyen T P, 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.
