1057-Reg-EXTL3通路驱动胰腺癌神经交互与进展研究
from 聊聊Sci
这项研究揭示了胰腺导管腺癌 (PDAC) 中神经与癌症相互作用的关键机制。研究发现，肿瘤周边的腺泡细胞在CD4+ T细胞产生的IL-22刺激下，会大量分泌Reg蛋白。这些蛋白通过作用于功能性受体EXTL3，一方面诱导神经纤维高度支配并增强神经兴奋性以引发疼痛，另一方面激活癌症内部的信号通路，提升肿瘤的侵袭性。通过临床样本分析与小鼠实验，作者证实了Reg-EXTL3轴在驱动神经周围浸润和病情恶化中的核心作用。因此，针对这一信号轴的干预可能成为缓解胰腺癌神经浸润及相关疼痛的新型治疗策略。References:Zhang S, Dong F Y, Cai S, 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.
