Using a method based on ESR spectroscopy and spin-trapping, we have shown that Abeta (amyloid beta-peptide) (implicated in Alzheimer's disease), alpha-synuclein (implicated in Parkinson's disease), ABri (British dementia peptide) (responsible for familial British dementia), certain toxic fragments of the prion protein (implicated in the transmissible(More)
Considerable evidence points to oxidative stress in the brain as an important event in the early stages of Alzheimer's disease (AD). The transition metal ions of Cu, Fe, and Zn are all enriched in the amyloid cores of senile plaques in AD. Those of Cu and Fe are redox active and bind to Aβ in vitro. When bound, they can facilitate the reduction of oxygen to(More)
The aggregation of amyloid-β peptides into protein fibres is one of the main neuropathological features of Alzheimer's disease (AD). While imaging of amyloid-β aggregate morphology in vitro is extremely important for understanding AD pathology and in the development of aggregation inhibitors, unfortunately, potentially highly toxic, early aggregates are(More)

One of the hallmarks of AD (Alzheimer's disease) is the formation of senile plaques in the brain, which contain fibrils composed of Aβ (amyloid β-peptide). According to the 'amyloid cascade' hypothesis, the aggregation of Aβ initiates a sequence of events leading to the formation of neurofibrillary tangles, neurodegeneration, and on to the main symptom of(More)
