An approach to characterize mechanisms of action of anti-amyloidogenic compounds in vitro and in situ

Amyloid aggregation is associated with neurodegenerative disease and its modulation is a focus of drug development. We developed a chemical proteomics pipeline to probe the mechanism of action of anti-amyloidogenic compounds. Our approach identifies putati ...

Differential role of C-terminal truncations on alpha-synuclein pathology and Lewy body formation

Graham Knott, Romain Hamelin, Anne-Laure Mahul Mellier, Nadine Aït Bouziad, Jonathan Jean-Pierre Ricci, Yllza Jasiqi, Mary-Claude Croisier-Coeytaux, Anass Chiki, Melek Firat Altay, Somanath Jagannath

Alpha-synuclein (aSyn) post-translational modifications (PTM), especially phosphorylation at serine 129 and C-terminal truncations, are highly enriched in Lewy bodies (LB), Lewy neurites, and other pathological aggregates in Parkinson's disease and synucle ...

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

Francesco Stellacci, Hilal Lashuel, Nadine Aït Bouziad, Paulo Henrique Jacob Silva, 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 ...

Phosphorylation of the overlooked tyrosine 310 regulates the structure, aggregation, and microtubule- and lipid-binding properties of Tau

Hilal Lashuel, Nadine Aït Bouziad, Anass Chiki, Galina Limorenko

The microtubule-associated protein Tau is implicated in the pathogenesis of several neurodegenerative disorders, including Alzheimer's disease. Increasing evidence suggests that post-translational modifications play critical roles in regulating Tau's norma ...

A method for preparing phfs-like tau aggregates

Hilal Lashuel, Nadine Aït Bouziad

The invention relates to a method for preparing PHFs-like Tau aggregates and to a method for identifying compounds that are inhibitors of Tau protein aggregation, blockers of Tau seeding and propagation, and imaging agents that specifically bind PHF. ...

Resolving molecule-specific information in dynamic lipid membrane processes with multi-resonant infrared metasurfaces

Hilal Lashuel, Daniel Rodrigo Lopez, Hatice Altug, Nadine Aït Bouziad, Andreas Tittl, Aurélian Michel John-Herpin, Odeta Limaj, Christopher David Kelly

A multitude of biological processes are enabled by complex interactions between lipid membranes and proteins. To understand such dynamic processes, it is crucial to differentiate the constituent biomolecular species and track their individual time evolutio ...

Discovery and characterization of novel stable tau oligomeric complexes: Implications for the role of Tau/phospholipid interactions in regulating its functions in health and disease

Hilal Lashuel, Anne-Laure Mahul Mellier, Nadine Aït Bouziad, Gizem Zorludemir

The microtubule-associated protein Tau plays a central role in the pathogenesis of Alzheimer's disease. Although Tau interaction with membranes is thought to affect some of its physiological functions and its aggregation properties, the sequence determinan ...

Sequence and structural determinants of Tau aggregation and seeding capacity: Implications for Neurofibrillary Tangle formation and Tau toxicity in Alzheimer's disease

Nadine Aït Bouziad

Despite decades of research in Alzheimerâ s disease (AD), no treatment has been found to efficiently prevent or cure its progression. The microtubule binding protein Tau plays central roles in the pathogenesis of AD and is found, in the form of paired hel ...

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 ...

Elucidating the Role of Site-Specific Nitration of alpha-Synuclein in the Pathogenesis of Parkinson's Disease via Protein Semisynthesis and Mutagenesis

Hilal Lashuel, Anass Chiki, Nadine Aït Bouziad, Ritwik Burai

Parkinsons disease (PD) is characterized by the loss of dopaminergic neurons in the substantia nigra and the presence of intraneuronal inclusions consisting of aggregated and post-translationally modified a-synuclein (a-syn). Despite advances in the chemic ...
