Prion diseases are untreatable neurodegenerative disorders characterized by accumulation of PrP(Sc), an aggregated isoform of the normal prion protein PrP(C). Here, we delivered the soluble prion antagonist PrP-Fc(2) to the brains of mice by lentiviral gen ...
Molecular dynamics (MD) simulations have increasingly contributed to the understanding of biomolecular processes, allowing for predictions of thermodynamic and structural properties. Unfortunately, the holy grail of protein structure prediction was soon fo ...
Aggregation and fibril formation of amyloid-β (Aβ) peptides play a pivotal role in the pathogenesis of Alzheimer's disease (AD). Aβ peptides, principally comprising of 40 or 42 amino acid residues (Aβ40 and Aβ42), are produced by proteolytic processing of ...
In the context of an ageing society neurodegenerative disease have become more and more frequent among humans. Opposing the benefits of a longer life, these diseases have thus triggered research on neurons and how they interact with each other. In vitro as ...
Protein aggregation is an established pathogenic mechanism in Alzheimer's disease, but little is known about the initiation of this process in vivo. Intracerebral injection of dilute, amyloid-beta (A beta)-containing brain extracts from humans with Alzheim ...
The molecular chaperone Hsp104 plays a central role in the clearance of aggregates after heat shock and the propagation of yeast prions. Hsp104's disaggregation activity and prion propagation have been linked to its ability to resolubilize or remodel prote ...
We perform a replica exchange molecular dynamics simulation corresponding to a 2.8 mu s total time for the extensive enhanced sampling of the conformational space of the C-terminal part (residues 124-226) of the mouse prion protein (PrP); 1.3% of the confo ...
The aggregation of proteins is central to many aspects of daily life, including food processing, blood coagulation, eye cataract formation disease and prion-related neurodegenerative infections[1–5]. However, the physical mechanisms responsible for amyloid ...
Numerous human diseases are associated with conformational change and aggregation of proteins, including Alzheimer's, Parkinson's, prion diseases (such as mad cow disease), familial amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), Huntington's ...
A misfolded conformer of the cellular prion protein, denoted as scrapie prion protein, is considered responsible for a variety of fatal neurodegenerative diseases. Both, the function of the protein in its native conformation as well as the factors that tri ...
