在长期接受抗抑郁药治疗(每日两次,持续2周)的大鼠纹状体和边缘系统的相同膜制备物中,测定了[3 H]SCH 23390与多巴胺D-1受体的结合以及[3 H]螺哌隆与D-2位点的结合。丙咪嗪、阿米替林、米安色林、西酞普兰、安非他酮、伊吲哚和电休克长期给药,但苯扎托品或赛庚啶(非抗抑郁药)不降低[3 H]SCH 23390结合位点的数量,而未观察到[3 H]螺哌隆结合参数的变化。在孵育培养基中加入阿托宁2受体拮抗剂酮色林时,对[3 H]SCH 23390与D-1位点的结合无影响。结果表明,D-1受体亚敏感性是抗抑郁药治疗效果的一个组成部分。
Binding of [3H]SCH 23390 to dopamine D-1 receptors and of [3H]spiperone to D-2 sites was measured in identical membrane preparations of the striatum and limbic system of rats treated chronically (twice daily, for two weeks) with antidepressants. Chronic administration of imipramine, amitriptyline, mianserin, citalopram, bupropion, iprindole and electroconvulsive shocks, but not benztropine or cyproheptadine (non-antidepressants) decreased the number of [3H]SCH 23390 binding sites, while no change in the parameters of [3H]spiperone binding was observed. The serotonin2receptor antagonist ketanserin when added to the incubation medium had no effect on [3H]SCH 23390 binding to D-1 sites. The results suggest that D-1 receptor subsensitivity is a component of the therapeutic effect of antidepressants.
