1063-小胶质细胞Rank信号调节GnRH神经元与生育力

这项研究揭示了下丘脑微胶质细胞通过Rank信号通路调节下丘脑-垂体-性腺 (HPG) 轴的关键机制。科学家利用多种小鼠模型发现，Rank基因的缺失会导致微胶质细胞活性降低及形态异常，进而干扰促性腺激素释放激素 (GnRH) 神经元的正常功能，最终引发性腺发育不全和不育。此外，研究还在人类先天性促性腺激素减退性性腺功能减退症 (CHH) 患者中识别出了RANK基因的罕见变异，进一步证实了该通路在人类生殖成熟中的重要性。实验表明，这种调节作用不仅发生在发育阶段，在成年期同样维持着生殖轴的稳定性。总之，该成果确立了微胶质细胞作为神经内分泌调节者的身份，并为生殖障碍疾病提供了潜在的诊断标准和治疗靶点。References:Collado-Sole A, Borjini N, Zhai J, et al.

Forfeiture Book Review: Ecocide and Sci-Fi JP et al. A whizz bang review of the complex themes in the new ecological Sci-Fi novel, FORFEITURE by JP Nebra 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.
