压力和酒精暴露都可能导致神经系统疾病。它们对中央杏仁核(CeA)等大脑区域的影响可能是压力相关和酒精使用障碍合并症高患病率的原因。κ阿片受体(KOR)系统与应激和慢性乙醇暴露有关,越来越多的证据表明,KOR系统及其内源性配体强啡肽(DYN)与这些疾病的表现密切相关(图1)。然而,DYN/KOR系统在这些疾病中的作用通常是独立研究的。虽然这些类型的研究是重要的和信息丰富的,但它们在精神疾病的临床前领域留下了很大的空白。为了充分治疗患有压力相关和酒精使用障碍共病的患者,必须进行更多的研究,以了解压力和酒精使用对彼此的相互作用和影响。Haun等人(1)在最新一期的《生物精神病学》中,强调了对共病进行研究的必要性。作者利用信使RNA(mRNA)测量、化学遗传学和药理学,为CeA DYN/KOR系统在介导应激诱导的酒精摄入量增加中的关键作用提供了令人信服的论据。为了确定压力对酒精摄入量的影响,作者使用了一种新颖且稳健的压力增强饮酒模型,该模型结合了慢性间歇性酒精暴露和强迫游泳应激(CIE+ FSS)。首先每天给予小鼠1小时的乙醇饮用期,持续4周,以建立基线饮用。然后将小鼠分开,
Both stress and alcohol exposure can lead to neurological disorders. Their impact on brain regions like the central amygdala (CeA) may underly the high prevalence of stress-related and alcohol use disorder comorbidities. The kappa opioid receptor (KOR) system is engaged by both stress and chronic ethanol exposure, and there is increasing evidence that together with its endogenous ligand, dynorphin (DYN), the KOR system is critically involved in the manifestation of these disorders (Figure 1). However, the role of the DYN/KOR system in these disorders is often studied independently. While these types of studies are important and informative, they leave a large gap in the preclinical field of psychiatric disorders. To adequately treat patients with comorbid stress-related and alcohol use disorders, more research must be done to understand the interaction and influence stress and alcohol use has on one another. Haun et al.(1), in the current issue of Biological Psychiatry, highlight the need for research focused on comorbidities. Using messenger RNA (mRNA) measurements, chemogenetics, and pharmacology, the authors provide a convincing argument for a critical role of the CeA DYN/KOR system in mediating stress-induced increases in alcohol consumption.To determine the influence of stress on alcohol intake, the authors use a novel and robust model of stress-enhanced alcohol drinking that incorporates chronic intermittent alcohol exposure and forced swim stress (CIE+ FSS). Mice were first given daily 1-hour ethanol drinking sessions for 4 weeks to establish baseline drinking. Mice were then separated
