1142-HER2 阳性乳腺癌的空间转录组解析与细胞交互图谱
from 聊聊Sci
这项研究利用空间转录组学技术，对八名患者的 HER2 阳性乳癌肿瘤样本进行了深度空间基因表达分析。通过将空间数据与单细胞测序结果相结合，研究人员成功绘制出了肿瘤微环境中细胞相互作用的高分辨率图谱。研究重点揭示了特定巨噬细胞与 T 细胞的共定位模式，并发现这一现象与 I 型干扰素反应密切相关。此外，团队还开发出一种预测模型，能够识别具有免疫预后意义的类三级淋巴结构。该成果不仅揭示了乳腺癌内部的分子异质性，还为跨组织和跨疾病的肿瘤研究提供了通用的空间分析工具。References:Andersson, A., Larsson, L., Stenbeck, L. 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.
