Protein aggregation plays a crucial role in neurodegenerative diseases. A key feature of protein aggregates is their ubiquitous modification by phosphorylation. Little is known, however, about the molecular consequences of phosphorylation of protein aggregates. Here we show that phosphorylation of β-amyloid at serine 8 increases the stability of its pathogenic aggregates against high-pressure a...
The cross-β amyloid form of peptides and proteins represents an archetypal and widely accessible structure consisting of ordered arrays of β-sheet filaments. These complex aggregates have remarkable chemical and physical properties, and the conversion of normally soluble functional forms of proteins into amyloid structures is linked to many debilitating human diseases, including several common ...
A hallmark of Alzheimer’s disease is the accumulation amyloid-β (Aβ) peptide. Donanemab, an antibody that targets a modified form deposited Aβ, being investigated for treatment early disease.
OBJECTIVES Neuroprotective effect of creatine (Cr) against β-amyloid (Aβ) is reported in an in vitro study. This study investigated the effect of Cr supplementation on β-amyloid toxicity in vivo. MATERIALS AND METHODS Thirty two, male Wistar rats were divided into 4 groups. During ten weeks of study, control group went through no surgical or dietary intervention. At the 4th week of study Sham...
Canine cognitive dysfunction (CCD) is a syndrome that manifests itself in abnormal behaviors, such as disorientation and wandering. β-amyloid deposition in the brain, including the senile plaque (SP) and cerebral amyloid angiopathy (CAA), has been suggested as a major cause of the syndrome. However, the pathological significance of β-amyloid deposition in CCD dogs remains unclear. The present s...
β-Secretase is an attractive target of amyloid-reduction therapy for Alzheimer's disease. Currently, no efficacy data is available from clinical trials of β-secretase inhibitors. Treating young transgenic Tg2576 mice with a brain-penetrating β-secretase inhibitor reduced brain amyloid-β by about 50% and rescued the age-related cognitive decline. Implications from these model studies on the desi...
In type 2 diabetes, the formation of islet amyloid consisting of islet amyloid polypeptide (IAPP) is associated with reduction in β-cell mass and contributes to the failure of islet cell transplantation. Rational design of inhibitors of IAPP amyloid formation has therapeutic potential, but is hampered by the lack of structural information on inhibitor complexes of the conformationally flexible,...
RATIONALE The prevalence of Alzheimer's disease is increased in people with Down syndrome. The pathology appears much earlier than in the general population, suggesting a predisposition to develop Alzheimer's disease. Down syndrome results from trisomy of human chromosome 21, leading to overexpression of possible Alzheimer's disease candidate genes, such as amyloid precursor protein gene. To be...
Alzheimer’s disease (AD), the leading cause of dementia, is a major cause of death and a significant economic burden. In 2016, ∼700,000 Americans aged 65 and over died of AD, and the total health and social care payments for AD in the United States alone exceeded $230 billion (1). Currently, there are no validated disease-modifying therapies that slow the progression of human AD. In PNAS, Ofeng...
