多发性硬化疾病模型

疾病简介

多发性硬化(multiple sclerosis,MS)是一种中枢神经系统慢性自身免疫性疾病,主要攻击大脑、脊髓和视神经中的神经髓鞘,导致神经信号传导受阻,引发多样化症状,如肢体麻木、乏力、视力下降(如视神经炎)、平衡障碍、认知功能减退等,病情常呈缓解 -复发交替的 “波动性” 进程,部分患者最终可能发展为进行性神经功能残疾。其病因与遗传、环境(如病毒感染、维生素 D 缺乏)、免疫异常等多因素相关。

疾病模型

实验性自身免疫性脑脊髓炎(experimental autoimmune encephalomyelitis,EAE)模型是探究多发性硬化症的关键动物模型。南模生物长期致力于自身免疫性疾病相关研究,基于不同诱导方法建立了多种 EAE 小鼠模型,为相关药物的药效评估和安全性评价提供了强有力的工具。
