Multiple Sclerosis (MS) is a neuroinflammatory disorder, which is histopathologically characterized by multifocal inflammatory demyelinating lesions affecting both the central nervous system's white and grey matter. Especially during the progressive phases of the disease, immunomodulatory treatment strategies lose their effectiveness. To develop novel progressive MS treatment options, pre-clinical animal models are indispensable. Among the various different models, the cuprizone de- and remyelination model is frequently used. While most studies determine tissue damage and repair at the histological and ultrastructural level, functional readouts are less commonly applied. Among the various overt functional deficits, gait and coordination abnormalities are commonly observed in MS patients. Motor behavior is mediated by a complex neural network that originates in the cortex and terminates in the skeletal muscles. Several methods exist to determine gait abnormalities in small rodents, including the rotarod testing paradigm. In this review article, we provide an overview of the validity and characteristics of the rotarod test in cuprizone-intoxicated mice.
多发性硬化症(MS)是一种神经炎症性疾病,其组织病理学特征为多发性炎症性脱髓鞘病变,影响中枢神经系统的白质和灰质。特别是在疾病的进展阶段,免疫调节治疗策略失去了效果。为了开发新的进展性多发性硬化症治疗选择,临床前动物模型是必不可少的。在各种不同的模型中,铜缺乏和再髓鞘模型经常被使用。虽然大多数研究在组织学和超微结构水平上确定组织损伤和修复,但功能读数应用较少。在各种明显的功能缺陷中,多发性硬化症患者通常会出现步态和协调异常。运动行为由起源于皮层并终止于骨骼肌的复杂神经网络介导。有几种方法可用于确定小型啮齿动物的步态异常,包括转棒测试范式。在这篇综述文章中,我们提供了铜缺乏诱导的小鼠旋转棒测试的有效性和特征的概述。
