Multiple system atrophy (MSA) is a fatal adult-onset neurodegenerative disorder of uncertain etiopathogenesis manifesting with autonomic failure, parkinsonism, and ataxia in any combination. The underlying neuropathology affects central autonomic, striatonigral and olivopontocerebellar pathways and it is associated with distinctive glial cytoplasmic inclusions (GCIs, Papp-Lantos bodies) that contain aggregates of α-synuclein. Current treatment options are very limited and mainly focused on symptomatic relief, whereas disease modifying options are lacking. Despite extensive testing, no neuroprotective drug treatment has been identified up to now; however, a neurorestorative approach utilizing autologous mesenchymal stem cells has shown remarkable beneficial effects in the cerebellar variant of MSA. Here, we review the progress made over the last decade in defining pathogenic targets in MSA and summarize insights gained from candidate disease-modifying interventions that have utilized a variety of well-established preclinical MSA models. We also discuss the current limitations that our field faces and suggest solutions for possible approaches in cause-directed therapies of MSA.
多系统萎缩(MSA)是一种病因不明的致命性成人起病的神经退行性疾病,表现为自主神经功能衰竭、帕金森综合征和共济失调的任意组合。其潜在的神经病理学改变影响中枢自主神经、纹状体黑质和橄榄脑桥小脑通路,并且与含有α-突触核蛋白聚集体的独特的胶质细胞胞质内含物(GCIs,帕-兰氏体)有关。目前的治疗选择非常有限,主要集中于症状缓解,而缺乏改善疾病的方法。尽管进行了广泛的测试,但迄今为止尚未确定神经保护药物治疗方法;然而,利用自体间充质干细胞的神经修复方法在MSA的小脑变异型中已显示出显著的有益效果。在此,我们回顾过去十年在确定MSA致病靶点方面取得的进展,并总结从利用各种成熟的临床前MSA模型的候选疾病改善干预措施中获得的见解。我们还讨论了该领域目前面临的局限性,并为MSA病因导向治疗的可能方法提出解决方案。
