[Abstract]  A vast challenge within neuropsychiatric research has been the development of animal models that accurately reflect symptoms associated with affective disorders. An ethologically valid model that has been shown to be effective in studying depression is the chronic social defeat stress model. In this model, C57BL/6J mice are subjected to chronic social defeat stress induced by CD-1 aggressor mice for 10 consecutive days. Discussed here is a protocol describing the screening process of the CD-1 aggressor mice, the confrontations between the C57BL/6J and CD-1 aggressor mice, and analysis of social avoidance scores as an indication of depression-like behaviors. [摘要]  神经精神科研究面临的巨大挑战是准确反映情感障碍症状的动物模型的发展。 已经显示出有效的研究抑郁症的病理学有效模型是慢性社会失败压力模型。 在该模型中,C57BL / 6J小鼠连续10天受CD-1侵袭小鼠诱导的慢性社会失败应激。 这里讨论的是描述CD-1侵略性小鼠的筛选过程的方案,C57BL / 6J和CD-1侵略性小鼠之间的对抗以及社会避免评分的分析作为抑郁症行为的指示。
【背景】抑郁症是全球影响约1.2亿人的复发和危及生命的状况。神经精神科研究领域的重要兴趣是开发有效的抑郁症动物模型,以帮助了解抑郁障碍的神经生物学和分子机制。已经使用各种慢性应激模型来诱导与抑郁有关的小鼠症状,其中包括慢性不可预测的应激,足部休克应激,固定应激,随后测量的是抗缺血或绝望样行为(例如蔗糖偏好测试,强制游泳试验和尾巴悬挂试验),但它们没有被很好地验证为人类抑郁症模型(Krishnan and Nestler,2011)。目前,慢性社会失败压力已经被广泛接受为抑郁症的有效证明模型,因为其可靠性和可重复性(Berton et al。,2006; Krishnan et al。,2007; Golden et al。,2011; Krishnan and Nestler ,2011; ...
