摘要/Abstract

摘要：

重度抑郁症已经成为困扰人类健康的重大疾病，传统的抗抑郁药物由于起效慢、不良反应大等缺陷，在临床应用中存在很大局限性。近年来，氯胺酮数小时起效的快速抗抑郁作用备受人们关注，但其神经机制不明了，制约了该药物的临床应用。2022年5月Nature Communications杂志发表Rawat等的研究报告，证实了小鼠海马齿状回中未成熟颗粒神经元的急性激活在氯胺酮的快速抗抑郁作用中扮演着关键角色。本文对这一研究做文献分析，并对后续相关工作进行展望。

Abstract:

Major depressive disorder is a serious disease that impacts human health worldwide. Traditional antidepressant medications are limited by the delayed onset of therapeutic effects and the unacceptable side effects. Recently, the rapid antidepressant effect of ketamine, which decreases depressive symptoms within hours, has been a very attractive finding in the field, but the underlying mechanisms mediating this rapid response remain unclear. Besides, the clinical application of ketamine still carries risks, such as addiction and deleterious side effects. In May 2022, Rawat et al. reported that the acute activation of adult-born immature granule neurons (ABINs) in the dentate gyrus played a key role in the rapid antidepressant effects of ketamine. This commentary reviews the important findings of this research and looks forward to the future work.

Key words: Major depressive disorder, Ketamine, Rapid antidepressant effect, Dentate gyrus, Adult-born immature granule neurons
