概括

多发性硬化症 (MS) 疼痛在麻或没有麻的小鼠中是可比的. 然而,涉到免疫细胞激活,脱髓化和脊髓中CXCL13的增加.

科学领域:

神经科学是一个神经科学.
免疫学免疫学免疫学
病理生理学病理生理学

背景情况:

多发性硬化症 (MS) 是一种神经退行性自身免疫性疾病,影响许多患者的疼痛和.
研究重点是实验性自身免疫脑膜炎 (EAE) 中的,这是MS的动物模型,对MS相关的疼痛的关注较少.
在MS中疼痛和运动症状的不同严重程度的潜在原因仍未得到充分研究.

研究的目的:

这项研究旨在在非PTX EAE模型中剖析MS症状的病理生理学.
该研究比较了经历机械过敏 (疼痛) 的小鼠,并没有麻.

主要方法:

利用非PTX EAE动物模型研究MS病理生理学.
评估了机械过敏,,免疫细胞激活和透,脱髓化,以及脊髓中CXCL13蛋白表达.

主要成果:

机械过敏性在患有和没有的EAE小鼠之间是可比的,不论性别.
与仅过敏的小鼠相比,具有机械过敏和的小鼠在脊髓中显著增加了免疫细胞激活和透,脱髓化和CXCL13蛋白水平.

结论:

在EAE中类似疼痛的表型不仅仅取决于的存在.
在EAE中,与脊髓的明显的病理变化有关,包括高度的神经炎症和脱髓化,可能由CXCL13介导.

关键词:

Multiple Sclerosis l: Introduction

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
