Although these two structures were already described when Alois Alzheimer reported the pathology of his patients in 1906, their biochemical constituents were not clarified until the 1980s. Senile plaque is an extracellular structure composed of b-amyloid protein (Ab), with peptides of approximately ...

Research on the molecular pathogenesis of Alzheimer's disease (AD) has made great strides over the last decade. This progress is the result of protein chemical analysis of two extracellular and intracellular fibrillary lesions in AD brain conducted during the 1980s, which identified β-amyloid prote...
The oligomer cascade hypothesis, which states that oligomers are the initiating pathologic agents in Alzheimer’s disease, has all but supplanted the amyloid cascade hypothesis, which suggested that fibers were the key etiologic agents in Alzheimer’s di
Understanding changes in pre-clinical Alzheimer's disease: Study finds two proteins impact brain activity differently Amyloid-beta and tau proteins have long been associated with Alzheimer's disease. The pathological buildup of these proteins leads to cognitive decline in people with the disease. How...
In 1907, Aloysius (Alois) Alzheimer described "senile" plaques and neurofibrillary tangles in a demented patient. Today we know that the plaques representextracellularamyloid derived from amyloid beta (Aβ) protein whereas the neurofibrillary tangles representintracellularamyloid formed on tau protein. ...
Imaging tau and amyloid-β proteinopathies in Alzheimer disease and other conditions Administration of a 1-phenylalkanecarboxylic acid before, after, or a concurrently with a therapeutically effective amount of one or more of the following: (1) β-amyloid peptides level reducers, (2) pathogenic ...
Beyond the neurotransmitter-focused approach in treating Alzheimer's disease: drugs targeting beta-amyloid and tau protein. 来自 NCBI 喜欢 0 阅读量: 51 作者:MD Francesco Panza,PhD,V Solfrizzi…摘要: Drugs currently used to treat Alzheimer's Disease (AD) have limited therapeutic value and do ...
Alzheimer’s disease (AD) is the most common cause of dementia, accounting for 60 to 80 percent of all cases [1]. The classic pathophysiological hallmarks of AD, including β-amyloid (Aβ), tau protein, and neurodegeneration, can be measured using cerebrospinal fluid (CSF) studies and imagin...
Alzheimer’s disease (AD) is the most common age-related form of dementia, associated with deposition of intracellular neuronal tangles consisting primarily of hyperphosphorylated microtubule-associated protein tau (p-tau) and extracellular plaques primarily comprising amyloid- β (Aβ) peptide. The p...
