快速起效的抗抑郁药氯胺酮和东莨菪碱对一些患者的行为影响可以持续数天到数周。维持这些抗抑郁药物作用的分子机制尚不清楚。在这里,我们发现甲基cpg结合蛋白2 (MeCP2) Ser421位点的磷酸化对于氯胺酮和东莨菪碱在小鼠中的持续抗抑郁作用是必要的,但不是快速的。我们的研究结果表明pMeCP2是BDNF的下游,BDNF是氯胺酮和东莨菪碱抗抑郁作用的关键因素。此外,我们发现pMeCP2是氯胺酮或东莨菪碱给药后突触强度的长期调节所必需的。这些结果表明pMeCP2和相关的突触可塑性是持续抗抑郁作用的重要决定因素。
The rapidly acting antidepressants ketamine and scopolamine exert behavioral effects that can last several days to weeks in some patients. The molecular mechanisms underlying the maintenance of these antidepressant effects are unknown. Here, we show that methyl-CpG-binding protein 2 (MeCP2) phosphorylation at Ser421 (pMeCP2) is essential for the sustained, but not the rapid, antidepressant effects of ketamine and scopolamine in mice. Our results reveal that pMeCP2 is downstream of BDNF, a critical factor in ketamine and scopolamine antidepressant action. In addition, we show that pMeCP2 is required for the long-term regulation of synaptic strength following ketamine or scopolamine administration. These results demonstrate that pMeCP2 and associated synaptic plasticity are essential determinants of sustained antidepressant effects.
