438. 增强衰老大脑记忆的分子研究

from 知为谁 · host 知为谁

来自弗吉尼亚理工大学新闻的摘录描述了两项独立的研究，其中研究人员成功地找到了改善年长受试者记忆的方法。这些研究在啮齿动物模型上进行，重点在于识别和调整与年龄相关的分子变化，以对抗记忆衰退。其中一项研究针对名为 K63 polyubiquitination 的分子标记系统，发现其在海马体和杏仁核中的变化与年龄相关，而调整这些变化可以改善记忆。第二项研究则集中于重新激活随着大脑老化而失活的 IGF2 基因，发现这也能显著改善年长受试者的记忆表现，表明记忆衰退是由多个分子系统共同作用的结果。内容来源：https://news.vt.edu/articles/2025/10/cals-jarome-improving-memory.html
