神经变性与阿尔茨海默病的两个标志性蛋白质--β淀粉样蛋白(Aβ)和tau蛋白之间的关系仍不清楚。在这里,我们检查了286名非痴呆的参与者(107名认知正常的老年人和179名记忆受损的人),他们接受了纵向MR成像和腰椎穿刺。使用混合效应模型,我们研究了纵向内嗅皮质萎缩、CSF p-tau 181 p和CSF Aβ1-42之间的关系。我们发现内嗅皮质萎缩升高与CSF Aβ1-42降低之间仅存在显著相关性,且CSF p-tau 181 p升高。我们的研究结果表明,Aβ相关的体积损失只发生在存在磷酸化tau蛋白的痴呆风险人群中。
The relationship between neurodegeneration and the two hallmark proteins of Alzheimer's disease, amyloid-β (Aβ) and tau, is still unclear. Here, we examined 286 non-demented participants (107 cognitively normal older adults and 179 memory impaired individuals) who underwent longitudinal MR imaging and lumbar puncture. Using mixed effects models, we investigated the relationship between longitudinal entorhinal cortex atrophy, CSF p-tau181p and CSF Aβ1-42. We found a significant relationship between elevated entorhinal cortex atrophy and decreased CSF Aβ1-42 only with elevated CSF p-tau181p. Our findings indicate that Aβ-associated volume loss occurs only in the presence of phospho-tauin humans at risk for dementia.
