1506-免疫抑制性非黑素瘤皮肤癌的单细胞空间图谱
from 聊聊Sci
这项研究利用空间多组学技术深入探讨了系统性免疫抑制对非黑素瘤皮肤癌肿瘤微环境的影响。研究人员发现，尽管免疫抑制患者与免疫健全患者在肿瘤内的免疫细胞总体比例相近，但其空间组织结构和T细胞克隆多样性存在显著差异。具体而言，免疫抑制患者表现出肿瘤内巨噬细胞密度降低以及先天与适应性免疫细胞之间的协调性受损。这些免疫微环境的改变与患者生存率下降及疾病预后不佳密切相关。研究通过整合单细胞测序和空间转录组学等方法，揭示了免疫抑制如何通过重塑免疫生态位来削弱抗肿瘤反应。这些发现为开发针对高危皮肤癌患者的新型局部免疫疗法提供了理论框架和数据支持。References:Naara S, Kochat V, Rao X, 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.
