Enforced dimerization between XBP1s and ATF6f enhances the protective effects of the UPR in models of neurodegeneration

Hilal Lashuel, Sonia Donzelli

Alteration to endoplasmic reticulum (ER) proteostasis is observed in a variety of neurodegenerative diseases associated with abnormal protein aggregation. Activation of the unfolded protein response (UPR) enables an adaptive reaction to recover ER proteost ...

Alpha-Synuclein oligomerization and aggregation: All models are useful but only if we know what they model This is the reply to a comment "Alpha-synuclein oligomerization and aggregation: A model will always be a model" on the original article "Monitoring alpha-synuclein oligomerization and aggregation using bimolecular fluorescence complementation assays: What you see is not always what you get". The articles are accompanied by a Preface "How good are cellular models?"

Hilal Lashuel

Alpha-synuclein oligomerization is one of the early events on the pathway to Lewy body formation. Therefore, interfering with this process holds tremendous potential for developing therapies that block alpha-Syn pathology formation and toxicity. The develo ...

Plasma neurofilament light and phosphorylated tau 181 as biomarkers of Alzheimer's disease pathology and clinical disease progression

Jonas Richiardi, Bénédicte Marie Maréchal, Christopher Clark

BackgroundTo assess the performance of plasma neurofilament light (NfL) and phosphorylated tau 181 (p-tau181) to inform about cerebral Alzheimer's disease (AD) pathology and predict clinical progression in a memory clinic setting.MethodsPlasma NfL and p-ta ...

Do Lewy bodies contain alpha-synuclein fibrils? and Does it matter? A brief history and critical analysis of recent reports

Hilal Lashuel

Several lines of evidence from neuropathological studies, human genetics, in vitro aggregation studies and cellular and animal models support the hypothesis that aSyn plays a central role in the formation of Lewy pathologies. These are cytoplasmic proteina ...

Pronounced α-synuclein pathology in a seeding-based mouse model is not sufficient to induce mitochondrial respiration deficits in the striatum and amygdala

Maria del Carmen Sandi Perez, Hilal Lashuel, Jean-Christophe Copin, Johannes Burtscher

Increasing evidence suggests that crosstalk between α-synuclein pathology formation and mitochondrial dysfunction plays a central role in the pathogenesis of Parkinson’s disease and related synucleinopathies. While mitochondrial dysfunction is a well-studi ...

The process of Lewy body formation, rather than simply α-synuclein fibrillization, is one of the major drivers of neurodegeneration

Graham Knott, Hilal Lashuel, Mary-Claude Croisier-Coeytaux, Fabien Kuttler, Marion Leleu, Anne-Laure Mahul Mellier, Niran Maharjan, Johannes Burtscher, Laura Emmeline H Weerens

Parkinson’s disease (PD) is characterized by the accumulation of misfolded and aggregated α-synuclein (α-syn) into intraneuronal inclusions named Lewy bodies (LBs). Although it is widely believed that α-syn plays a central role in the pathogenesis of PD, t ...

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 ...

New insights on the structure of alpha-synuclein fibrils using cryo-electron microscopy

Henning Paul-Julius Stahlberg, Ricardo Cesar Guerrero Ferreira, Dongchun Ni

Fibrils of alpha-synuclein are significant components of cellular inclusions associated with several neuropathological disorders including Parkinson’s disease, multiple system atrophy and dementia with Lewy bodies. In recent years, technological advances i ...

How specific are the conformation-specific α-synuclein antibodies? Characterization and validation of 16 α-synuclein conformation-specific antibodies using well-characterized preparations of α-synuclein monomers, fibrils and oligomers with distinct structures and morphology

Hilal Lashuel, Somanath Jagannath

Increasing evidence suggests that alpha-synuclein (α-syn) oligomers are obligate intermediates in the pathway involved in α-syn fibrillization and Lewy body (LB) formation, and may also accumulate within LBs in Parkinson's disease (PD) and other synucleino ...

Discovery of 2-(4-(2-fluoroethoxy)piperidin-1-yl)-9-methyl-9H-pyrrolo[2,3-b:4,5-c']dipyridine ([18F]PI-2014) as PET tracer for the detection of pathological aggregated tau in Alzheimer's disease and other tauopathies

Andrea Pfeifer

The compound screening was initiated with a direct staining assay to identify compounds binding to Tau aggregates and not Abeta plaques using human brain sections derived from late stage Alzheimer's disease donors. The binding of Tau aggregate selective co ...

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. ...

Dopaminergic neurodegeneration induced by Parkinson's disease-linked G2019S LRRK2 is dependent on kinase and GTPase activity

Darren Moore, Elpida Tsika, Xi Chen

Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common cause of late-onset, autosomal-dominant familial Parkinson's disease (PD). LRRK2 functions as both a kinase and GTPase, and PD-linked mutations are known to influence both enzymatic acti ...
