1417-ZBP1介导巨噬细胞焦亡加重脓毒症相关肺损伤
from 聊聊Sci
这份研究通过整合人类和小鼠的单细胞转录组数据,揭示了ZBP1蛋白在败血症诱发急性肺损伤中的核心致病机制。研究发现,一类特定的促炎巨噬细胞在病程中显著增加,并通过ZBP1与NLRP3的相互作用触发细胞焦亡。这种细胞死亡过程释放了大量炎性因子,直接破坏了肺泡上皮细胞的线粒体功能和屏障完整性。实验证明,敲除Zbp1基因能有效阻断巨噬细胞与上皮细胞间的有害通讯,显著减轻肺部炎症损伤。该发现为开发针对败血症相关器官衰竭的靶向治疗策略提供了重要科学依据。References:Zhou F, Tian H, Wang H, 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.
