341-耐受铁死亡促进气道炎症中的脂质代谢和2型免疫
from 聊聊Sci
这篇研究论文探讨了在过敏性气道炎症中，第二型固有淋巴细胞 (ILC2) 和辅助性 T 细胞 (Th2) 如何通过代谢适应性驱动致病性免疫反应。研究发现，这些致病性免疫细胞依赖于胱氨酸来合成谷胱甘肽 (GSH)，从而构建一个强大的抗氧化和抗铁死亡通路。这种对铁死亡的耐受性（一种铁依赖性细胞死亡形式）对于维持细胞的脂质代谢至关重要，从而促进了 ILC2 和 Th2 细胞的增殖和积累。论文指出，靶向 GPX4 和 TXNRD1 等抗氧化系统，可以作为治疗气道炎症的潜在代谢脆弱性靶点，并显示了药理学抑制 TXNRD1 能够减轻 ILC2 驱动的气道炎症。References: Wientjens C, Doverman M, Zurkovic J, 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.
