Popis: | Antidepressants currently used in clinical practice have limitations such as low efficacy, slow onset and various adverse reactions. It has become necessary to develop novel antidepressants beyond monoaminergic drugs. L-701,324 is a potent NMDA receptor antagonist, and the purpose of this study was to investigate the possible antidepressant effects of L-701,324 in mice. Here, various methods including the forced swim test (FST), tail suspension test (TST), chronic unpredictable mild stress (CUMS) model of depression, western blotting and immunofluorescence, were used together. A single injection of L-701,324 exhibited antidepressant-like potential in the FST and TST without affecting the locomotor activity of mice. Repeated injection of L-701,324 not only prevented CUMS-induced depressive-like behaviors in mice, but also ameliorated the downregulating effects of CUMS on the hippocampal BDNF signaling cascade and neurogenesis. Furthermore, K252a, a potent inhibitor of the BDNF system, fully blocked the antidepressant-like activity of L-701,324 in mice. K252a administration also abolished the activating actions of L-701,324 on the hippocampal BDNF signaling cascade and neurogenesis in CUMS-treated mice. Collectively, these data indicated that L-701,324 possesses antidepressant-like activity in mice, which was mediated, at least in part, by promoting the hippocampal BDNF system. |
