The aggregation of amyloid-beta peptide and tau protein dysregulation are implicated to play key roles in Alzheimer's disease pathogenesis and are considered the main pathological hallmarks of this devastating disease. Physiologically, these two proteins are produced and expressed within the normal human...
关于Amyloid和Tau的假说StressMarq 斑块, 缠结以及阿尔茨海默氏症的病理学 阿尔茨海默氏症 (AD) 是一种神经衰退疾病，随着全球人口老龄化，这种病也越来越常见。虽然目前还没有有效的治疗方案，但是科学家们经过一个多世纪的研究已经对该病的发展进程有了更好的了解。AD患者的大脑有以下两个主要特征：含有β淀粉样肽的...

Beta amyloidTauMemoryExecutive FunctionsNeuroimagingAlzheimer’s disease (AD) is associated with a cascade of pathological events involving formation of amyloid-based neuritic plaques and tau-based neurofibrillary tangles, changes in brain structure and function, and eventually, cognitive impairment and ...
We modelled biomarker changes as a function of CSF Aβ42/40, p-tau and p-tau/Aβ42 as proxies of disease progression. The first change observed in the Alzheimer's continuum was a decrease in the CSF Aβ42/40 ratio. This is followed by a steep increase in CSF p-tau; t-tau; ...
反对Tau 蛋白假说的证据 可惜的是,很多抗-tau 的治疗方案也都没有通过临床试验。糖原合成酶激酶 3 beta (GSK-3β) 是促进 tau 磷酸化的一种蛋白激酶,也因此成为抗-tau 治疗方案很具吸引力的一个靶点。然而,Tideglusib, 一种GSK-3β 抑制剂,并没有在二期临床试验中显示出明显的治疗效果31。

In both amyloid-β (Aβ) and tau Caenorhabditis elegans models of AD, mitophagy stimulation (through NAD+ supplementation, urolithin A, and actinonin) reverses memory impairment through PINK-1 (PTEN-induced kinase-1)-, PDR-1 (Parkinson’s disease-related-1; parkin)-, or DCT-1 (DAF-16/...
