Electrochemical, Photoelectrochemical and Electrochemiluminescent Biosensors for the Detection of Betaamyloid Peptides and Their Aggregates

International Journal of Electrochemical Science, 2019
Beta-amyloid (Aβ) peptides are the specific biomarkers of Alzheimer's disease (AD). Many clinical studies have suggested that abnormal levels of Aβ peptides in blood, cerebrospinal fluid and brain tissue are closely related to the progression of AD ...

Amyloid tracers detect multple binding sites in Alzheimer´s disease brain tissue. [PDF]

, 2013
Imaging fibrillar amyloid-β deposition in the human brain in vivo by positron emission tomography has improved our understanding of the time course of amyloid-β pathology in Alzheimer’s disease. The most widely used amyloid-β imaging tracer so far is 11C-

Brain Region-Specific Differences in Amyloid-β Plaque Composition in 5XFAD Mice

Life, 2023
Senile plaques consisting of amyloid-beta (Aβ) peptides are a major pathological hallmark of Alzheimer’s disease (AD). Aβ peptides are heterogeneous regarding the exact length of their amino- and carboxy-termini. Aβ1-40 and Aβ1-42 are often considered to

Mitochondrial β-amyloid in Alzheimer's disease

, 2011
This research is supported by Alzheimer's Research UK, the Wellcome Trust and the Biotechnology and Biological Sciences Research Council.It is well established that the intracellular accumulation of beta-amyloid is associated with Alzheimer’s disease and

Probing oligomerization of amyloid beta peptide in silico

Molecular BioSystems, 2016
Abstract Aggregation of amyloid β (Aβ) peptide is implicated in fatal Alzheimer's disease, for which no cure is available. Understanding the mechanisms responsible for this aggregation is required in order for therapies to be developed.

Oligomers mediate the spatial transmission of Aβ peptide aggregation

Communications Chemistry
Alzheimer’s disease (AD) is marked by the abnormal aggregation of amyloid-beta peptides within the central nervous system. The formation of amyloid fibrils from amyloid-beta peptides is a hallmark of AD Here, we demonstrate that the aggregation of ...

Mulberry Fruit Cultivar ‘Chiang Mai’ Prevents Beta-Amyloid Toxicity in PC12 Neuronal Cells and in a Drosophila Model of Alzheimer’s Disease

Molecules, 2020
Alzheimer’s disease (AD) is the most common form of dementia, characterized by chronic neuron loss and cognitive problems. Aggregated amyloid beta (Aβ) peptides, a product of cleaved amyloid precursor protein (APP) by beta-secretase 1 (BACE-1), have been

Neurodevelopmental disorders and microcephaly: how apoptosis, the cell cycle, tau and amyloid-β precursor protein APPly

Frontiers in Molecular Neuroscience, 2023
Recent studies promote new interest in the intersectionality between autism spectrum disorder (ASD) and Alzheimer’s Disease. We have reported high levels of Amyloid-β Precursor Protein (APP) and secreted APP-alpha (sAPPa) and low levels of amyloid-beta ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Amyloid Beta Peptide Is Released during Thrombosis in the Skin [PDF]

International Journal of Molecular Sciences, 2018
While it is known that amyloid beta (Aβ) deposits are found in different tissues of both Alzheimer’s disease (AD) patients and healthy individuals, there remain questions about the physiological role of these deposits, the origin of the Aβ peptide, and the mechanisms of its localization to the tissues.
