546-髓母细胞瘤中Yap1调控免疫逃避的性别差异研究
from 聊聊Sci
这项研究探讨了Yap1基因在髓母细胞瘤（MB）中的致癌机制，并揭示了生物性别如何显著影响癌症与免疫系统之间的相互作用。实验表明，虽然Yap1对肿瘤的初始形成并非必不可少，但它是肿瘤持续进展的关键驱动因素。研究人员发现，在小鼠模型中敲除该基因对雄性具有更显著的治疗效益，能有效延长生存期并激活更强的抗肿瘤免疫反应。相比之下，雌性机体内的肿瘤更易通过免疫抑制机制产生耐药性。数据进一步显示，Yap1通过调节CD276和STAT3等通路直接控制肿瘤的干细胞特性及免疫微环境。最终，这些发现强调了在开发免疫疗法时，必须针对不同性别制定差异化的精准治疗策略。References: Abdelfattah N, Natarajan S, Tran H N, 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.
