584-GPLD1与TNAP调控老年认知及脑血管功能研究
from 聊聊Sci
这项研究探讨了运动产生的循环因子如何缓解大脑衰老及阿尔茨海默病。研究重点关注肝脏产生的酶 GPLD1，它能通过调节脑血管内源性酶 TNAP 的活性来改善认知功能。实验数据表明，提高 GPLD1 水平或抑制 TNAP 可以修复血脑屏障的完整性，并减少神经炎症。在老年小鼠和患病模型中，这种机制成功恢复了受损的学习与记忆能力。通过单细胞测序分析，研究进一步揭示了相关疗法如何将基因表达谱恢复至更年轻的状态。总之，该成果揭示了全身代谢与大脑健康之间的关键联系，为开发抗衰老药物提供了新路径。References: Bieri G, Pratt K J B, Fuseya Y, 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.
