Reverse engineering Lewy bodies: how far have we come and how far can we go?

Hilal Lashuel, Mohamed Bilal Fares, Somanath Jagannath

Lewy bodies (LBs) are α-synuclein (α-syn)-rich intracellular inclusions that are an important pathological hallmark of Parkinson disease and several other neurodegenerative diseases. Increasing evidence suggests that the aggregation of α-syn has a central ...

Investigating Crosstalk Among PTMs Provides Novel Insight Into the Structural Basis Underlying the Differential Effects of Nt17 PTMs on Mutant Httex1 Aggregation

Hilal Lashuel, Matteo Dal Peraro, Luciano Andres Abriata, Lucien Fabrice Krapp, Anass Chiki, Iman Rostami, Driss Boudeffa, Zhidian Zhang

Post-translational modifications (PTMs) within the first 17 amino acids (Nt17) of the Huntingtin protein (Htt) have been shown to inhibit the aggregation and attenuate the toxicity of mutant Htt proteins in vitro and in various models of Huntington’s disea ...

To target Tau pathologies, we must embrace and reconstruct their complexities

Hilal Lashuel, Galina Limorenko

The accumulation of hyperphosphorylated fibrillar Tau aggregates in the brain is one of the defining hallmarks of Tauopathy diseases, including Alzheimer's disease. However, the primary events or molecules responsible for initiation of the pathological Tau ...

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 ...

Half a century of amyloids: past, present and future

Hilal Lashuel, Raffaele Mezzenga

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 ...

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 ...

Effects of sedimentation, microgravity, hydrodynamic mixing and air-water interface on alpha-synuclein amyloid formation

Giovanni Dietler, Giovanni Longo, Francesco Simone Ruggeri, Jiangtao Zhou

The formation of amyloid fibrils is a characterizing feature of a range of protein misfolding diseases, including Parkinson's disease. The propensity of native proteins to form such amyloid fibril, both in vitro and in vivo, is highly sensitive to the surr ...

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 ...

Nanoscale Characterization of Amyloid Fibrils and Biomacromolecules by Atomic Force Microscopy Approaches

Jiangtao Zhou

This thesis focuses on the interdisciplinary biophysical research field, in which physical approaches are applied to study the biological phenomena. Specifically, the main object of the research in this thesis is to target biological species,especially the ...

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 ...
