504-泛癌肿瘤免疫微环境的空间图谱与特征研究
from 聊聊Sci
这项发表在《细胞报告医学》上的研究通过对2,019件肿瘤样本的深度分析，构建了一个涵盖14种主要癌症类型的泛癌症空间蛋白组学图谱。研究团队利用多重免疫荧光技术精确捕捉了3,940万个细胞的空间位置，并提炼出五个在不同癌种间普遍存在的肿瘤免疫微环境（TIME）空间因子。这些因子不仅量化了免疫细胞的富集程度与分布模式，还揭示了空间组织结构与基因组改变及患者生存预后之间的紧密联系。研究通过主成分分析定义了诸如“免疫富集”和“免疫逃逸”等维度，为理解肿瘤免疫互动提供了标准化工具。此外，作者还发布了一个大规模的单细胞空间数据库，旨在为全球癌症免疫学研究和精准医疗开发提供关键的参考资源。References: Pan-cancer spatial characterization of key immune biomarkers in the tumor microenvironmentLindsay, James R. et al.Cell Reports Medicine, Volume 0, Issue 0, 102418前往小宇宙评论区与主播互动

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.
