1565-非黑素细胞皮肤癌免疫抑制空间图谱
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色素瘤皮肤癌（NMSC）患者肿瘤微环境的具体影响。尽管免疫抑制患者与免疫功能正常者的整体免疫细胞比例相似，但前者在肿瘤内部的巨噬细胞密度显著降低且T细胞克隆多样性受限。研究发现，这种免疫状态导致了先天免疫与适应性免疫在空间组织上的重塑，而不仅仅是细胞数量的简单减少。通过对器官移植受者及血液肿瘤患者的临床分析，实验证实了这些空间分布的改变与患者生存率下降密切相关。该成果为开发针对高危患者的局部免疫治疗提供了新的生物标志物和潜在靶点。这种整合了单细胞测序与空间转录组学的分析框架，为理解复杂免疫背景下的癌症进展提供了重要资源。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.
