Retraction Notice
The article Assisted Selection of Biomarkers by Linear Discriminant Analysis Effect Size (LEfSe) in Microbiome Data (10.3791/61715) has been retracted by the journal upon the authors' request due to a conflict regarding the data and methodology. View Retraction Notice
来源:Gonsalvez, D. G., et al., 一种在 C57BL/6 小鼠中诱导实验性自身免疫性神经炎的简单方法,用于功能和神经病理学评估。J. Vis. Exp. (2017 年)。
该视频演示了通过施用百日咳毒素和含有髓鞘模拟肽和佐剂的接种物来评估小鼠模型中运动功能障碍的过程,然后进行跑步机测试以评估运动功能并评估由于免疫激活和脱髓鞘而产生的神经损伤。
所有涉及动物模型的程序均已由当地机构动物护理委员会和 JoVE 兽医审查委员会审查。
1. EAN(实验性自身免疫性神经炎)诱导
注意:可以在 6-8 周龄的雄性 C57BL/6 小鼠中成功诱导 EAN。诱导方案总共需要 9 天。第 0 天是指第一次免疫接种的日期。对于该方案,注射在麻醉下进行(参见下面的步骤 1.1.2)。
2. 运动功能评估
注意:运动性能与同一组动物的临床评分同时进行评估。运动功能评估设备必须连接到安装了步态功能成像系统(见材料表)的计算机。还建议所有要评估的小鼠在 EAN 诱导之前都应习惯于跑步任务。为此,在疾病诱导前三天(第 -3 天)进行练习运行(每只小鼠 2 次测试运行)。
