概括
多发性硬化症 (MS) 的thalamic缩与网络断开和微质变化有关,而不是脱髓化. 了解这些因素对于开发用于MS患者的神经保护疗法至关重要.
科学领域:
- 神经科学是一个神经科学.
- 免疫学 免疫学 免疫学
- 神经病理学神经病理学
背景情况:
- 甲状腺缩是多发性硬化症 (MS) 的早期和渐进性特征.
- 在多发性硬化中,thalamic 脱髓化并不总是与观察到的缩相关.
- 研究乳头缩病理驱动因素对于了解多发性硬化症进展至关重要.
研究的目的:
- 为了确定多发性硬化症 (MS) 中的胸膜缩的病理贡献者.
- 为了将微观结构完整性,髓化,炎症和微质激活与MS的乳头缩相关联.
- 探索乳头亚核体积变化与相关白质通道和细胞病理之间的关系.
主要方法:
- 综合性死后磁共振成像 (MRI) 和免疫组织化学在MS和对照捐赠者的乳头组织上.
- 使用扩散权重成像评估了四个乳头核群体的体积和连接白质道的微观结构完整性.
- 通过免疫组织化学量化髓化,炎症,神经退行以及微质激活.
主要成果:
- 在MS中,中部和后部的乳头核比前部和侧部核有更大的缩.
- 观察到与后部,中部和前部乳头核相连的白质区域的分数异构性减少.
- 在中脊核中增加的微质细胞密度和复杂性与中部体体积的减少相关,表明前突触的细胞化没有整体突触损失.
结论:
- 在MS中,thalamic亚核缩与结构网络断开和intrathalamic微质变化有关.
- 在MS的thalamic缩并不是由脱髓化驱动的.
- 研究结果表明,在多发性硬化症中,thalamic神经保护具有新的治疗点.

Alzheimer Disease ll: Pathophysiology
35
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
