Oligomerization Profile of Human Transthyretin Variants with Distinct Amyloidogenicity

One of the molecular hallmarks of amyloidoses is ordered protein aggregation involving the initial formation of soluble protein oligomers that eventually grow into insoluble fibrils. The identification and characterization of molecular species critical for ...

A simple, versatile and robust centrifugation-based filtration protocol for the isolation and quantification of alpha-synuclein monomers, oligomers and fibrils: Towards improving experimental reproducibility in alpha-synuclein research

Hilal Lashuel, Anass Chiki, Sonia Donzelli, Muhammed Muazzam Kamil Syed

Increasing evidence suggests that the process of alpha-synuclein (alpha-syn) aggregation from monomers into amyloid fibrils and Lewy bodies, via oligomeric intermediates plays an essential role in the pathogenesis of different synucleinopathies, including ...

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 ...

Unraveling the complexity of amyloid polymorphism using gold nanoparticles and cryo-EM

Hilal Lashuel, Anass Chiki, Nadine Aït Bouziad, Francesco Stellacci, Paulo Henrique Jacob Silva, Marie Mueller, Zekiye Pelin Güven, Sophie Vieweg, Urszula Beata Cendrowska

Increasing evidence suggests that amyloid polymorphism gives rise to different strains of amyloids with distinct toxicities and pathology-spreading properties. Validating this hypothesis is challenging due to a lack of tools and methods that allow for the ...

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. ...

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 ...

Diffusion MRI biomarkers of white matter microstructure vary nonmonotonically with increasing cerebral amyloid deposition

Ileana Ozana Jelescu

Beta amyloid (A beta) accumulation is the earliest pathological marker of Alzheimer's disease (AD), but early AD pathology also affects white matter (WM) integrity. We performed a cross-sectional study including 44 subjects (23 healthy controls and 21 mild ...

Expert recommendation from the Swiss Amyloidosis Network (SAN) for systemic AL-amyloidosis

Alessio Mylonas, Andrea Cavalli, Martin Meyer

Systemic amyloidosis is a heterogeneous group of diseases associated with protein misfolding into insoluble beta-sheet rich structures that deposit extracellularly in different organs, eventually compromising their function. There are more than 30 differen ...

The Clustering of mApoE Anti-Amyloidogenic Peptide on Nanoparticle Surface Does Not Alter Its Performance in Controlling Beta-Amyloid Aggregation

Francesco Stellacci, Paulo Henrique Jacob Silva

The deposition of amyloid-beta (A beta) plaques in the brain is a significant pathological signature of Alzheimer's disease, correlating with synaptic dysfunction and neurodegeneration. Several compounds, peptides, or drugs have been designed to redirect o ...
