Discontinuous Galerkin methods for Fisher-Kolmogorov equation with application to a-synuclein spreading in Parkinson's disease

Alfio Quarteroni, Francesca Bonizzoni

This spreading of prion proteins is at the basis of brain neurodegeneration. This paper deals with the numerical modelling of the misfolding process of a-synuclein in Parkinson's disease. We introduce and analyse a discontinuous Galerkin method for the sem ...

Trans‐seeding of Alzheimer‐related tau protein by a yeast prion

Henning Paul-Julius Stahlberg, Zhiva Skachokova

Abnormal tau protein aggregates constitute a hallmark of Alzheimer's disease. The mechanisms underlying the initiation of tau aggregation in sporadic neurodegeneration remain unclear. Here we investigate whether a non-human prion can seed tau aggregation. ...

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

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

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. The deposition of highly ordered fibrillar-type aggregates into inclusion bodies is a hallm ...

Oligomerization Profile of Human Transthyretin Variants with Distinct Amyloidogenicity

Bruno Emanuel Ferreira De Sousa Correia

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 fo ...

The metalloprotease ADAMTS4 generates N-truncated A4-x species and marks oligodendrocytes as a source of amyloidogenic peptides in Alzheimer's disease

Patrick Fraering, Mitko Dimitrov, Hermeto Gerber, Sandra Lehmann

Brain accumulation and aggregation of amyloid- (A) peptides is a critical step in the pathogenesis of Alzheimer's disease (AD). Full-length A peptides (mainly A1-40 and A1-42) are produced through sequential proteolytic cleavage of the amyloid precursor pr ...

TDP-43 extracted from frontotemporal lobar degeneration subject brains displays distinct aggregate assemblies and neurotoxic effects reflecting disease progression rates

Henning Paul-Julius Stahlberg, Amanda Jennifer Lewis, Tariq Afroz

Accumulation of abnormally phosphorylated TDP-43 (pTDP-43) is the main pathology in affected neurons of people with amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Morphological diversity and neuroanatomical distribution o ...

Microtubule-Binding R3 Fragment from Tau Self-Assembles into Giant Multistranded Amyloid Ribbons

Hilal Lashuel, Nadine Aït Bouziad, Raffaele Mezzenga

Tau protein and its fragments self-assemble into amyloid fibrils in the presence of polyanions, such as heparin. By combining microscopy, scattering, and spectroscopy techniques, we studied the aggregation of the 26-mer Tau-derived peptide alone, Tau306-32 ...

An Intein-based Strategy for the Production of Tag-free Huntingtin Exon 1 Proteins Enables New Insights into the Polyglutamine Dependence of Httex1 Aggregation and Fibril Formation

Hilal Lashuel, Annalisa Ansaloni, Sophie Vieweg, John Blaine Warner IV

The first exon of the Huntingtin protein (Httex1) is one of the most actively studied Htt fragments because its overexpression in R6/2 transgenic mice has been shown to recapitulate several key features of Huntington disease. However, the majority of bioph ...
