1453-CFTR介导的肝癌免疫微环境重塑与联合治疗研究
from 聊聊Sci
这篇研究论文揭示了CFTR（囊性纤维化跨膜电导调节因子）在肝细胞癌（HCC）中的抑癌作用及其免疫调节机制。研究发现，CFTR在肝癌组织中显著低表达，且其表达水平与肿瘤的恶性程度呈负相关。通过激活或过表达CFTR，可以有效降低细胞内氯离子和钙离子浓度，进而抑制RUNX1和NF-κB信号通路，减少促癌细胞因子的分泌。这种机制成功将肿瘤微环境从免疫抑制状态重塑为激活状态，表现为M1型巨噬细胞和CD8+ T细胞浸润增加，同时抑制了调节性T细胞。最终，CFTR的激活与PD-L1抗体展现出显著的协同治疗效应，为提升肝癌免疫治疗疗效提供了新的生物标志物和联合用药方案。References:Xu Y, Sun J, He 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.
