each slightly different, known as R1, R2, R3, and R4. In the brains of people with Alzheimer’s and other neurodegenerative diseases, abnormal versions of Tau form stringy filaments that clump together, causing tangles in the brain.

Tau是一种与微管相关的蛋白，主要在大脑部分表达，其功能是稳定轴突微管。tau蛋白存在的三种形式分别是：寡聚体、错误折叠和磷酸化。先前研究表明，tau蛋白过度磷酸化形成神经原纤维缠结（neurofibrillary tangles, NFTs），NFT具有神经毒性，导致神经元凋亡和进一步的阿尔兹海默症发病机理。作者利用不同抗体和免疫金电子...
PART主要神经病理表现主要为海马和颞中叶有轻度-中度神经元内NFTs、包括细胞死亡致NFT外溢的鬼影缠结(ghost tangles),但缺乏Aβ斑块。此神经元tau病理也可见于基底核、黑质、蓝斑和伏隔核;甚至约10%患者可有海马硬化。新近日本提出高龄糖尿病患者发生的糖尿病相关性痴呆(Diabetes...
β-淀粉样肽异常沉积形成淀粉样斑块(amyloid plaques),tau蛋白高度磷酸化且异常聚集形成神经原纤维缠结 (neurofibrillary tangles),这些都是起始之后数年痴呆(dementia)状态的内在病理变化。通过正电子发射断层扫描(positron emission tomography,简称PET)对淀粉样肽和tau蛋白进行同位素放射性示踪(radiotracers),每位病人的上述...
Alzheimer’s disease (AD) is the most common cause of late onset dementia and is characterized by the development of pathological amyloid plaques and tau tangles in the brain1. While late onset AD is an age-related disease, results from twin and family studies have emphasized that ~50% of ...
