There is a broad consensus that multiple sclerosis (MS) represents more than an inflammatory disease: it harbors several characteristic aspects of a classical neurodegenerative disorder, that is, damage to axons, synapses and nerve cell bodies. While we are equipped with appropriate therapeutic options to prevent immune-cell driven relapses, effective therapeutic options to prevent the progressing neurodegeneration are still missing. In this review article, we will discuss to what extent pathology of the progressive disease stage can be modeled in MS animal models. While acute and relapsing-remitting forms of experimental autoimmune encephalomyelitis (EAE), which are T cell dependent, are aptly suited to model relapsing-remitting phases of MS, other EAE models, especially the secondary progressive EAE stage in Biozzi ABH mice is better representing the secondary progressive phase of MS, which is refractory to many immune therapies. Besides EAE, the cuprizone model is rapidly gaining popularity to study the formation and progression of demyelinating CNS lesions without T cell involvement. Here, we discuss these two non-popular MS models. It is our aim to point out the pathological hallmarks of MS, and discuss which pathological aspects of the disease can be best studied in the various animal models available.
人们普遍认为,多发性硬化症(MS)不仅仅是一种炎症性疾病:它具有经典神经退行性疾病的几个特征,即轴突、突触和神经细胞体受损。虽然我们有适当的治疗方法来预防免疫细胞驱动的复发,但仍缺少预防进行性神经退行性变的有效治疗方法。在这篇综述文章中,我们将讨论在MS动物模型中可以在多大程度上模拟疾病进展阶段的病理情况。虽然依赖T细胞的实验性自身免疫性脑脊髓炎(EAE)的急性和复发缓解形式适合模拟MS的复发缓解阶段,但其他EAE模型,特别是Biozzi ABH小鼠的继发进展性EAE阶段,更能代表MS的继发进展阶段,这一阶段对许多免疫疗法都具有抗性。除了EAE,铜螯合剂模型在研究无T细胞参与的脱髓鞘中枢神经系统病变的形成和进展方面正迅速受到欢迎。在这里,我们讨论这两种不太常用的MS模型。我们的目的是指出MS的病理特征,并讨论在现有的各种动物模型中,该疾病的哪些病理方面可以得到最好的研究。
