591-颅骨骨髓-脑肿瘤免疫互作机制研究
from 聊聊Sci
这项研究探讨了儿童脑肿瘤如何利用胚胎时期的免疫特征来逃避检测，并寻找比传统放疗或化疗更有效的免疫疗法。研究发现，肿瘤产生的信号可以通过脑脊液传递到颅骨骨髓，从而抑制免疫系统的正常反应。通过对人类样本和小鼠模型的单细胞分析，科学家识别出了导致免疫力下降的特定细胞通路。实验表明，阻断GM-CSF受体并结合抗CTLA-4治疗，可以显著提高患病个体的存活率。这些发现揭示了脑部特有的免疫抑制机制，并为开发针对性更强、毒性更低的临床治疗方案提供了重要依据。References: Cooper E, Posner D A, Lee C Y C, 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.
