摘要

背景:冲动性可以被定义为一种异质性结构,其特征是难以抑制行动和过早决策。虽然高度冲动被认为是大麻使用障碍的一个危险因素,但大麻素对冲动选择的影响却很少被探索。目的:本研究旨在确定CB1/2激动作用对延迟贴现任务(DDT)大鼠冲动选择的急性和持续性影响。方法:将经训练的成年雄性Sprague-Dawley大鼠分别注射CB1/2激动剂WIN 55212-2(0.1、1和5 mg/kg)的对照剂或增加剂量,并在DDT中进行试验。结果:我们的研究结果显示,WIN55212-2的作用与高冲动性大鼠的基线冲动性和冲动性降低相关,而对低冲动性大鼠没有影响。最后一次注射WIN55212-2 2周后,给大鼠注射载体,再次暴露于DDT。高冲动大鼠的AUClog值维持在显著的高水平,表明WIN 55212-2具有持久的作用。最后,CB1受体拮抗剂利莫那班(1mg /kg)逆转了WIN55212-2反复治疗对高冲动人群冲动的影响,表明CB1/2受体在WIN55212-2的持续作用中发挥了积极作用。结论:我们的研究结果表明,CB1/2激动剂在高冲动水平的弱势亚群中具有潜在的益处。为了最大限度地提高治疗效益,最大限度地减少潜在的医源性影响,评估选择冲动和其他变量是必不可少的,与个性化医疗原则保持一致,以有效地定制干预措施。

"Modulatory role of baseline impulsivity on the acute and persistent effects of CB1 agonism on impulsive choice".

Background: Impulsivity may be defined as a heterogeneous construct characterized by difficulties in inhibiting actions and premature decision-making. Although a high level of impulsivity is recognized as a risk factor for cannabis use disorder, the effects of cannabinoids on impulsive choices have been less explored.

Aims: This study aimed to determine the acute and persistent effects of CB1/2 agonism on impulsive choice in rats using a delay-discounting task (DDT).

Methods: Trained adult male Sprague-Dawley rats were injected with either vehicle or increasing doses (0.1, 1, and 5 mg/kg) of the CB1/2 agonist WIN 55212-2 and tested in the DDT.

Results: Our results showed that the effect of WIN55212-2 correlated with baseline impulsivity and reduced impulsivity in rats classified as high impulsive, while no effect was observed in rats classified as low impulsivity. Two weeks after the last WIN55212-2 injection, the rats were injected with vehicle and re-exposed to DDT. Rats classified as high impulsive maintained a significantly high AUClog value, suggesting a long-lasting effect of WIN 55212-2. Finally, the CB1 receptor antagonist rimonabant (1 mg/kg) reversed the effect of repeated treatment with WIN55212-2 on impulsivity in the high-impulsive population, suggesting an active role of the CB1/2 receptor in the persistent effect of WIN55212-2.

Conclusions: Our results suggest a potential benefit of CB1/2 agonism in vulnerable subpopulations with high levels of impulsivity. To maximize therapeutic benefits and minimize potential iatrogenic effects, assessing choice impulsivity and other variables is essential, aligning with personalized medicine principles to effectively tailor interventions.

期刊介绍: The Journal of Psychopharmacology is a fully peer-reviewed, international journal that publishes original research and review articles on preclinical and clinical aspects of psychopharmacology. The journal provides an essential forum for researchers and practicing clinicians on the effects of drugs on animal and human behavior, and the mechanisms underlying these effects. The Journal of Psychopharmacology is truly international in scope and readership.
