1285-针对ARC综合征的慢病毒基因治疗研究
from 聊聊Sci
该研究探讨了利用慢病毒基因治疗手段，针对罕见的遗传性ARC综合征（关节挛缩、肾功能障碍及胆汁淤积）所导致的致命性肝脏疾病的开发与评估。研究人员通过小鼠模型对比了肝脏特异性载体（LP1-VPS）与广谱性载体（EF1-VPS）的安全性，发现前者能有效避免后者诱发的肝肿瘤风险。实验证明，在结合短暂抑制巨噬细胞的条件下，LP1-VPS载体能成功修复受损的VPS33B蛋白功能。这种疗法显著改善了实验动物的生存率、生长状况以及肝脏生化指标，并重建了正常的胆小管结构。该成果为ARC综合征及其他早发型遗传性肝病提供了一种极具前景的靶向治疗方案。References:Cozmescu C A, Nazari M, Touramanidou L, 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.
