1476-ILC2调节胰腺成纤维祖细胞生态位研究
from 聊聊Sci
该研究揭示了2型固有淋巴细胞（ILC2）在调控胰腺成纤维细胞稳态与病理演变中的核心作用。研究发现，ILC2与具有祖细胞潜能的Pi16+Dpp4+Ly6c+成纤维细胞共同存在于胰腺的间质生态位中。通过分泌IL-13，ILC2能够刺激这些祖细胞增殖，并促进其分化为实质内的成纤维细胞或癌症相关成纤维细胞（CAF）。在胰腺炎引发的组织损伤修复过程中，这一免疫-基质轴对于重建器官基质和设定炎症阈值至关重要。此外，在胰腺癌背景下，该细胞群的扩张直接影响了肿瘤相关基质的密度与成分。总之，ILC2作为关键的“编舞者”，局部精确编排了胰腺在健康、炎症及癌症状态下的细胞地形图。References:Yip T, Stockis J, Simpson 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.
