概括

与疾病相关的微质细胞 (DAM) 在肌缩性侧面硬化症 (ALS) 中表现出炎症反应. 像TREM2,CD33和MS4A这样的关键基因是升高的,这表明它们在ALS病理学中的作用和潜在的治疗标.

科学领域:

神经科学是一个神经科学.
免疫学免疫学免疫学
遗传学遗传学是一个

背景情况:

神经炎症,特别是涉及微质细胞,与肌缩性侧面硬化症 (ALS) 病理生理学有关.
与疾病相关的微质 (DAM) 是神经退行性疾病中观察到的独特的微质状态.
了解ALS中微质基因表达对于确定治疗点至关重要.

研究的目的:

研究ALS患者脊髓中微质相关基因的表达模式.
为了比较ALS中的恒常性和与疾病相关的微质细胞之间的基因表达特征.
为了确定在ALS进展期间参与微质反应的特定基因.

主要方法:

使用RT-qPCR对mRNA表达水平的分析.
检查 ALS 和对照捐赠者的死后脊髓组织.
基因与微质恒温和DAM状态相关的基因的量化.

主要成果:

与对照人群相比,ALS脊髓组织中TREM2,MS4A,CD33,APOE和TYROBP的表达增加 (p < 0.05).
在ALS和对照组之间没有观察到TMEM119,SPP1和LPL基因表达的显著差异.
这些发现表明,在ALS中存在特定的微质基因失调.

结论:

建议在ALS中存在DAM介导的炎症反应.
在ALS的背景下,TREM2在微质免疫功能中发挥着重要作用.
支持CD33和MS4A作为参与ALS生理病理学的基因,突出显示它们作为治疗点的潜力.

Alzheimer Disease ll: Pathophysiology

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 microglia. Abnormal...
