787-放射协同诱导型AAV平台编程抗肿瘤免疫
from 聊聊Sci
这项研究揭示了放射治疗（RT）与腺相关病毒（AAV）免疫疗法之间的协同机制，为癌症治疗提供了新策略。研究发现，放电能通过表观遗传重塑显著增强肿瘤对AAV向量的转导效率。科学家据此设计了一种干扰素诱导型AAV平台，实现了细胞因子IL-12在辐照肿瘤区域的精准空间控制。这种组合疗法能重塑肿瘤微环境，有效诱导局部及全身性的抗肿瘤免疫反应。实验证明，该方法在多种模型中均能抑制肿瘤生长，且避免了传统细胞因子疗法常见的全身毒性。最终，这种治疗方案利用IFNγ依赖和FAS介导的机制，成功克服了肿瘤的免疫逃逸。References: Marco S, Fernández M, Honorato B, 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.
