摘要:
背景:>
Methods: We focused on hippocampal microRNAs (miRNAs) that could directly bind toand are regulated by Rb1 to explore the possible synaptic plasticity-dependent mechanism of Rb1, which affords protection against CUMS-induced depression-like effects.
Results: Herein, we observed that brain-specific miRNA-134 (miR-134) could directly bind to3UTR and was markedly downregulated by Rb1 in the hippocampus of暴露于暨的小鼠。此外,海马靶向的miR-134过表达基本上阻断了抗抑郁药RB1在行为测试过程中的KE效应,减轻对神经元核免疫性神经元的影响,树突状棘的密度,突触超微结构,长期增强以及突触与突触相关的蛋白质和BDNF-trkb信号蛋白在结论: 这些数据提供了有力的证据,表明RB1通过通过miR-134介导的BDNF信号通路来调节海马突触可塑性来挽救了暨诱导的抑郁症状。
