锂限制性AD病理
金属在脑功能中起着至关重要的作用,但金属体内平衡的改变是否以及如何影响阿尔茨海默病(AD)仍然知之甚少。Aron等人发表在《自然》杂志上的一项研究发现,内源性锂(Li)稳态被破坏是AD病理的一个关键因素。使用电感耦合等离子体质谱法,研究人员发现轻度认知障碍和AD患者血液和前额皮质中的Li水平降低,可能是由于淀粉样蛋白-β的隔离。在AD小鼠模型和老年小鼠中,暴露于缺乏锂的饮食减少了小胶质淀粉样蛋白-β清除,增加了tau病理和神经炎症,部分通过GSK3β激活,以及学习和记忆受损。单核RNA测序显示,Li-deficient AD模型小鼠的各种脑细胞类型与AD患者的大脑中具有相同的基因表达模式。值得注意的是,用枸橼酸锂治疗AD模型小鼠和老年小鼠可以减少炎症,恢复小胶质细胞功能,并显著减少AD病理和记忆障碍。这些发现强调了内源性Li稳态在认知弹性中的关键作用,并提示其在脑衰老和AD中的治疗潜力。原始参考文献:Nature https://doi.org/10.1038/s41586-025-09335-x (2025)

期刊介绍: Nature Neuroscience, a multidisciplinary journal, publishes papers of the utmost quality and significance across all realms of neuroscience. The editors welcome contributions spanning molecular, cellular, systems, and cognitive neuroscience, along with psychophysics, computational modeling, and nervous system disorders. While no area is off-limits, studies offering fundamental insights into nervous system function receive priority. The journal offers high visibility to both readers and authors, fostering interdisciplinary communication and accessibility to a broad audience. It maintains high standards of copy editing and production, rigorous peer review, rapid publication, and operates independently from academic societies and other vested interests. In addition to primary research, Nature Neuroscience features news and views, reviews, editorials, commentaries, perspectives, book reviews, and correspondence, aiming to serve as the voice of the global neuroscience community.
