The pathogenesis of Alzheimer's disease involves the progressive accumulation of amyloid β-protein (Aβ). Recent studies using synthetic Aβ peptides, a cell culture model, Aβ precursor protein transgenic mice models suggest that pre-fibrillar forms of Aβ are more deleterious than extracellular fibril forms. Recent findings obtained using synthetic Aβ peptides and human samples indicated that low-n oligomers (from dimers to octamers) may be proximate toxins for neuron and synapse. Here, we review the recent studies on the soluble oligomers, especially low-n oligomers in Alzheimer's disease.
阿尔茨海默病的发病机制涉及淀粉样β-蛋白(Aβ)的进行性积累。最近使用合成 Aβ 肽、细胞培养模型、Aβ 前体蛋白转基因小鼠模型的研究表明,Aβ 的预纤维形式比细胞外纤维形式更具危害性。最近使用合成 Aβ 肽和人类样本获得的发现表明,低聚物(从二聚体到八聚体)可能是神经元和突触的近毒物质。在这里,我们回顾了最近关于可溶性低聚物,特别是阿尔茨海默病中低聚物的研究。
