小鼠的老化将肠道细菌的变化与通过 vagus 神经炎导致的记忆丧失联系起来,并正在研究潜在的治疗方法。 Aging in mice links gut bacteria changes to memory loss via vagus nerve inflammation, with potential treatments under study.

对小鼠进行的一项新研究将与老龄化有关的认知衰落与内脏微生物的改变联系起来,后者通过 vagus神经干扰肠胃脑的交流。 A new study in mice links aging-related cognitive decline to changes in the gut microbiome that disrupt gut-brain communication via the vagus nerve. 随着小鼠的老化,某些直肠细菌增加并产生可触发炎症、损害神经信号和减少记忆功能的代谢物。 As mice age, certain gut bacteria increase and produce metabolites that trigger inflammation, impairing nerve signaling and reducing memory function. 将微生物从老小鼠转移到年轻小鼠,造成了记忆缺陷,同时消除了肠道细菌或刺激了 vagus神经,从而扭转了这些影响。 Transferring microbiomes from old to young mice caused memory deficits, while removing gut bacteria or stimulating the vagus nerve reversed these effects. 调查结果表明,将肠道健康或神经活动作为目标可能有助于防止记忆丧失,尽管需要进行人类研究来证实这些结果。 Findings suggest targeting gut health or nerve activity could help prevent memory loss, though human studies are needed to confirm these results.
