Capturing the heterogeneity of alpha-synuclein pathology in synucleinopathies
Synucleinopathies such as Parkinson's disease, dementia with Lewy bodies and multiple system atrophy (MSA) are detrimental neurodegenerative diseases. Alpha-synuclein (aSyn), the main aggregating protein found in the pathological inclusions of these ailmen ...
EPFL2022Prominent astrocytic alpha-synuclein pathology with unique post-translational modification signatures unveiled across Lewy body disorders
Hilal Lashuel, Melek Firat Altay
Alpha-synuclein (aSyn) is a pre-synaptic monomeric protein that can form aggregates in neurons in Parkinson's disease (PD), Parkinson's disease with dementia (PDD) and dementia with Lewy bodies (DLB), and in oligodendrocytes in multiple system atrophy (MSA ...
BMC2022Pathological Relevance of Post-Translationally Modified Alpha-Synuclein (pSer87, pSer129, nTyr39) in Idiopathic Parkinson's Disease and Multiple System Atrophy
Hilal Lashuel, Melek Firat Altay
Aggregated alpha-synuclein (alpha-synuclein) is the main component of Lewy bodies (LBs), Lewy neurites (LNs), and glial cytoplasmic inclusions (GCIs), which are pathological hallmarks of idiopathic Parkinson's disease (IPD) and multiple system atrophy (MSA ...
MDPI2022Lewy body-associated proteins: Victims, instigators, or innocent bystanders? The case of AIMP2 and alpha-synuclein
Hilal Lashuel, Salvatore Novello
Lewy bodies (LBs), one of the neuropathological defining hallmarks of Parkinson's disease (PD), are composed of a complex mixture of alpha-synuclein (aSyn) filaments and hundreds of proteins, lipids, and membranous organelles. However, these proteins' role ...
2021Reverse 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 ...
2021Molecular 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 ...
NATURE RESEARCH2020Gold nanoparticles as a new tool in amyloid studies
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-β sheet structure, called amyloids. Amyloids can ...
EPFL2020Effects 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 ...
ROYAL SOC CHEMISTRY2020How 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 ...
2020Single-molecule studies of amyloid proteins: from biophysical properties to diagnostic perspectives
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 ...
