氟西汀是一种用于治疗重度抑郁症和其他精神疾病的药物。这些实验研究了长期氟西汀治疗对小鼠的背景与听觉恐惧记忆的影响。我们发现,慢性氟西汀治疗成年小鼠损害了他们的背景恐惧记忆,但幸免听觉恐惧记忆。海马神经束膜神经元网络,这是涉及上下文的恐惧记忆可塑性,氟西汀治疗没有改变。这些数据表明,氟西汀治疗导致选择性无法形成情境恐惧记忆,并且它们表明,抑制大脑介导的厌恶记忆可能是这种药物的治疗作用。
Fluoxetine is a medication used to treat Major Depressive Disorder and other psychiatric conditions. These experiments studied the effects of chronic fluoxetine treatment on the contextual versus auditory fear memory of mice. We found that chronic fluoxetine treatment of adult mice impaired their contextual fear memory, but spared auditory fear memory. Hippocampal perineuronal nets, which are involved in contextual fear memory plasticity, were unaltered by fluoxetine treatment. These data point to a selective inability to form contextual fear memory as a result of fluoxetine treatment, and they suggest that a blunting of hippocampal-mediated aversive memory may be a therapeutic action for this medication.
