Half a century of amyloids: past, present and future

Amyloid diseases are global epidemics with profound health, social and economic implications and yet remain without a cure. This dire situation calls for research into the origin and pathological manifestations of amyloidosis to stimulate continued develop ...

Gold nanoparticles as a new tool in amyloid studies

Urszula Beata Cendrowska

The misfolding and self-assembly of proteins into fibrils is a hallmark of several neurodegenerative and systemic diseases. These disease-associated proteins have the propensity to form fibrils with a cross-Î² sheet structure, called amyloids. Amyloids can ...

Single-molecule studies of amyloid proteins: from biophysical properties to diagnostic perspectives

Chan Cao

In neurodegenerative diseases, a wide range of amyloid proteins or peptides such as amyloid-beta and alpha-synuclein fail to keep native functional conformations, followed by misfolding and self-assembling into a diverse array of aggregates. The aggregates ...

Molecular dissection of amyloid disaggregation by human HSP70

Paolo De Los Rios, Alessandro Barducci

The molecular steps that lead to the disaggregation of amyloid fibrils are shown to involve the synergistic action of HSP70 and its co-chaperones DNAJB1 and HSP110. The deposition of highly ordered fibrillar-type aggregates into inclusion bodies is a hallm ...

NATURE RESEARCH2020

Alzheimer's disease (AD) is the most common form of dementia in the elderly. AD is characterized by the deposition of two aggregated proteins: Amyloid beta (Aß) and hyperphosphorylated tau. Accumulations of these proteins are thought to be the signature ...

Membrane–Protein–Hydration Interaction of α-Synuclein with Anionic Vesicles Probed via Angle-Resolved Second-Harmonic Scattering

Sylvie Roke, Jan Dedic, Halil Ibrahim Okur

Amyloid formation of the protein α-synuclein promotes neurodegeneration in Parkinson's disease. The normal function of α-synuclein includes synaptic vesicle transport and fusion, and the protein binds strongly to negatively charged vesicles in vitro. Here, ...

Endogenous Regulators of Gamma-Secretase and Amyloid-Beta Production, and Engineering of Alzheimer's Disease Therapeutic Tools

Sébastien Mosser

Alzheimer s disease (AD) is a devastating neurodegenerative disease characterized by strong cognitive impairment and memory loss. These symptoms are caused by neuronal death, induced by two pathological hallmarks: extracellular senile plaques composed of a ...

Passive immunization against toxic misfolded proteins could offer protection against neurodegenerative disease. LathuiliSre et al. report the development of a retrievable device to encapsulate cells secreting recombinant anti-amyloid-beta antibodies. When ...

Effect of the Synaptic Plasma Membrane on the Stability of the Amyloid Precursor Protein Homodimer

Matteo Dal Peraro, Alessandro Barducci, Thomas Lemmin, Martina Audagnotto

The proteolytic cleavage of the transmembrane (TM) domain of the amyloid precursor protein (APP) releases amyloid-beta (A beta) peptides, which accumulation in the brain tissue is an early indicator of Alzheimer's disease. We used multiscale molecular dyna ...

Amer Chemical Soc2016

Background: Beside neurofibrillary tangles, amyloid plaques are the major histological hallmarks of Alzheimer's disease (AD) being composed of aggregated fibrils of beta-amyloid (A beta). During the underlying fibrillogenic pathway, starting from a surplus ...
