摘要:

孤独症谱系障碍(autism spectrum disorder, ASD)是一种遗传相关的神经系统发育性疾病,患者主要呈现社交缺陷、沟通障碍、重复刻板行为和学习记忆障碍等核心症状。小鼠模型是探究孤独症谱系障碍的致病机理和寻找潜在治疗方法的重要工具,而小鼠行为学的观测和分析可以帮助人们更好地了解不同遗传操作对相应孤独症表型的影响,从而阐释疾病机理。本文列举了针对孤独症患者核心缺陷的相关小鼠行为学分析方法,包括检测社交缺陷的三厢社交实验、居住者-入侵者实验、筑巢实验和超声波检测;检测重复刻板行为的Y迷宫自主选择实验、捋毛实验、刻板行为分析实验和弹珠埋藏实验;检测焦虑行为的旷场实验、高架十字迷宫实验和明暗穿梭实验;检测学习和记忆障碍的新事物选择实验和水迷宫实验。本文详细描述了这些行为学实验的标准操作流程、注意事项以及规范的数据分析方法,可以帮助研究人员进行相关实验设计。同时本文对已知孤独症小鼠遗传模型中的各项行为学表型进行了汇总和比较,为相关研究人员提供系统参照。

Abstract:

Autism spectrum disorder is a group of genetically-related developmental disorders of the nervous system. Patients mainly present with core symptoms such as social behavior defects, repetitive stereotyped behaviors, and learning and memory disorders. The mouse models are critical for the studies of the pathogenic mechanisms and potential therapeutic strategies of autism spectrum disorder. The assessments of mouse behaviors provide understandings of the effects of different genetic manipulations as well as pathogenic mechanisms of these diseases. This article describes various mouse behavioral assays corresponding to the core symptoms of ASD patients and provides a detailed description of protocols, cautions, and data analysis for those assays, thereby helping researchers to establish their own experimental designs. In addition, behavioral phenotypes of currently known ASD mouse models are summarized to provide a reference for researchers in the field.
