Although the opioid system is known to modulate depression-like behaviors, its role in the effects of antidepressants is not yet clear. We investigated the role of μ-opioid receptors (MOPs) in the effects of venlafaxine, a serotonin and norepinephrine reuptake inhibitor, in the forced swim test using MOP-knockout (KO) mice. Venlafaxine reduced immobility time in wild-type mice (C57BL/6J), but not in MOP-KO mice, although no significant effects were observed on locomotor activity. These results suggest that MOPs play an important role in the antidepressant-like effects of venlafaxine.
尽管阿片系统被认为可以调节抑郁样行为,但它在抗抑郁药作用中的作用尚不清楚。我们使用μ-阿片受体(MOP)敲除(KO)小鼠研究了文拉法辛(一种 5-羟色胺和去甲肾上腺素再摄取抑制剂)对强迫游泳试验的影响。文拉法辛可减少野生型(C57BL/6J)小鼠的不动时间,但对 MOP-KO 小鼠则没有,尽管对运动活性没有观察到显著影响。这些结果表明 MOP 在文拉法辛的抗抑郁样作用中发挥重要作用。
