1484-神经活动诱导的免疫介导突触损耗
from 聊聊Sci
这项研究揭示了神经元过度活跃是触发成年大脑补体系统（C1q）介导突触丢失的关键因素。研究人员通过化学遗传学手段发现，海马体的病理性兴奋会诱导B淋巴细胞系产生的免疫球蛋白（特别是IgM）与突触结合，从而协助C1q对特定神经末梢进行标记与清除。在阿尔茨海默症模型中，通过抑制神经元过度兴奋可有效减少C1q沉积并保护突触。这一发现确立了先天性与适应性免疫系统之间的跨界协作机制，为理解疾病状态下的神经回路重塑提供了全新视角。这些证据共同表明，调节免疫反应和控制神经活动对于防治神经退行性疾病具有潜在的临床意义。References:Crowley G, Kim M, O’Neill N, 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.
