Development and validation of an expanded antibody toolset that captures alpha-synuclein pathological diversity in Lewy body diseases

Hilal Lashuel, Johannes Burtscher, Melek Firat Altay, Somanath Jagannath

The abnormal aggregation and accumulation of alpha-synuclein (aSyn) in the brain is a defining hallmark of synucleinopathies. Various aSyn conformations and post-translationally modified forms accumulate in pathological inclusions and vary in abundance amo ...

Phantom Boarder Relates to Experimentally‐Induced Presence Hallucinations in Parkinson's Disease

Olaf Blanke, Fosco Bernasconi, Jevita Potheegadoo

Phantom boarder (PB) is the sensation that someone uninvited is in the patient's home despite evidence to the contrary. It is mostly reported by patients with neurodegenerative disorders such as Alzheimer's disease, dementia with Lewy bodies or Parkinson's ...

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 ...

Capturing the heterogeneity of alpha-synuclein pathology in synucleinopathies

Melek Firat Altay

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 ...

Prominent 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 ...

Pathological 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 ...

Towards elucidating the structural and cellular determinants of a-synuclein seeding and toxicity

Somanath Jagannath

Although it has been nearly two and half decades since the discovery of alpha-synuclein (aSyn) as the major component of Lewy bodies (LBs), our understanding of the involvement of different aSyn species, their seeding, spreading and toxicity in Parkinson's ...

Alpha-synuclein as a Potential Biomarker for Parkinson’s Disease and Other Synucleinopathies: Gaps, Challenges, and Opportunities

Hilal Lashuel

Parkinson's disease (PD), the second most common progressive neurodegenerative disease, develops and progresses for 10-15 years before the clinical diagnostic symptoms of the disease are manifested. Furthermore, several aspects of PD pathology overlap with ...

Opportunities and challenges of alpha-synuclein as a potential biomarker for Parkinson's disease and other synucleinopathies

Hilal Lashuel, Pedro José Santana Ribeiro Magalhães

NATURE PORTFOLIO2022

Pathological substrate of memory impairment in multiple system atrophy

Hilal Lashuel, Melek Firat Altay

Aims: Synaptic dysfunction in Parkinson's disease is caused by propagation of pathogenic alpha-synuclein between neurons. Previously, in multiple system atrophy (MSA), pathologically characterised by ectopic deposition of abnormal alpha-synuclein predomina ...
