摘要
多发性硬化症(MS)和神经脊髓炎视神经谱系障碍(NMOSD)是两种最具破坏性的免疫介导的中枢性脱髓鞘疾病。NMOSD 曾一度被认为是多发性硬化症的一种变异,直到发现了一种针对这种疾病的特异性抗体。尽管多发性硬化症和 NMOSD 都被认为是中枢性脱髓鞘疾病,但它们的发病机制和临床表现却截然不同,然而与每种疾病相关的确切机制仍不清楚。细胞外囊泡(EVs)是源自各种细胞的纳米级囊泡,是细胞间的交流媒介。大量证据表明,EVs 在多种疾病的发病机制中可能发挥作用,包括免疫介导的中枢性脱髓鞘疾病。在疾病的各个阶段都能发现各种类型的 EVs,它们有可能被用作替代标记物,并通过携带生化分子货物发挥作用。EVs被用作免疫介导的中枢脱髓鞘疾病的下一代靶向治疗的可能性已被研究。本综述旨在全面确定、汇编和讨论体外、体内和临床研究的主要发现。所有研究结果的总结显示1)多发性硬化症和 NMOSD 的 EV 特征与健康人不同;2)使用 EV 标记作为液体活检诊断工具似乎是治疗多发性硬化症和 NMOSD 的有前途的生物标记物;3)EV 正在被研究作为治疗多发性硬化症和 NMOSD 的潜在靶向疗法。本综述还讨论了任何有争议的发现。
Possible Roles of Extracellular Vesicles in the Pathogenesis and Interventions of Immune-Mediated Central Demyelinating Diseases.
Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) are two of the most devastating immune-mediated central demyelinating disorders. NMOSD was once considered as a variant of MS until the discovery of an antibody specific to the condition. Despite both MS and NMOSD being considered central demyelinating disorders, their pathogenesis and clinical manifestations are distinct, however the exact mechanisms associated with each disease remain unclear. Extracellular vesicles (EVs) are nano-sized vesicles originating in various cells which serve as intercellular communicators. There is a large body of evidence to show the possible roles of EVs in the pathogenesis of several diseases, including the immune-mediated central demyelinating disorders. Various types of EVs are found across disease stages and could potentially be used as a surrogate marker, as well as acting by carrying a cargo of biochemical molecules. The possibility for EVs to be used as a next-generation targeted treatment for the immune-mediated central demyelinating disorders has been investigated. The aim of this review was to comprehensively identify, compile and discuss key findings from in vitro, in vivo and clinical studies. A summary of all findings shows that: 1) the EV profiles of MS and NMOSD differ from those of healthy individuals, 2) the use of EV markers as liquid biopsy diagnostic tools appears to be promising biomarkers for both MS and NMOSD, and 3) EVs are being studied as a potential targeted therapy for MS and NMOSD. Any controversial findings are also discussed in this review.
期刊介绍:
Experimental Neurobiology is an international forum for interdisciplinary investigations of the nervous system. The journal aims to publish papers that present novel observations in all fields of neuroscience, encompassing cellular & molecular neuroscience, development/differentiation/plasticity, neurobiology of disease, systems/cognitive/behavioral neuroscience, drug development & industrial application, brain-machine interface, methodologies/tools, and clinical neuroscience. It should be of interest to a broad scientific audience working on the biochemical, molecular biological, cell biological, pharmacological, physiological, psychophysical, clinical, anatomical, cognitive, and biotechnological aspects of neuroscience. The journal publishes both original research articles and review articles. Experimental Neurobiology is an open access, peer-reviewed online journal. The journal is published jointly by The Korean Society for Brain and Neural Sciences & The Korean Society for Neurodegenerative Disease.
