多发性硬化症(MS)是一种中枢神经系统慢性脱髓鞘疾病,在病程早期发现神经变性,并与患者的长期残疾有关。神经变性与炎症和脱髓鞘有关,但其确切原因仍不清楚。这种知识的差距导致目前缺乏治疗MS的神经退行性阶段。在这里,我们问MS中的神经退行性病变是否会影响特定的神经元成分,以及它是否是脱髓鞘的结果。继发性进行性MS运动皮质的神经病理学检查显示MS中抑制性中间神经元的选择性脆弱性。局灶性软膜下皮质脱髓鞘的啮齿动物模型的产生再现了这种选择性神经变性,为神经保护治疗的研究提供了新的临床前模型。在线版本包含补充材料,可通过10.1007/s 00401 -020-02258-z获得。
In multiple sclerosis (MS), a chronic demyelinating disease of the central nervous system, neurodegeneration is detected early in the disease course and is associated with the long-term disability of patients. Neurodegeneration is linked to both inflammation and demyelination, but its exact cause remains unknown. This gap in knowledge contributes to the current lack of treatments for the neurodegenerative phase of MS. Here we ask if neurodegeneration in MS affects specific neuronal components and if it is the result of demyelination. Neuropathological examination of secondary progressive MS motor cortices revealed a selective vulnerability of inhibitory interneurons in MS. The generation of a rodent model of focal subpial cortical demyelination reproduces this selective neurodegeneration providing a new preclinical model for the study of neuroprotective treatments.
