Shotgun Metagenomic Profiling of the Gut Virome in Prodromal and Confirmed Parkinson's Disease

Annals of Neurology, EarlyView.
We conducted a nested case‐control study within the Nurses’ Health Study and the Health Professionals Follow‐up Study to examine the role of the gut virome (GV) in Parkinson's disease (PD). We applied a novel metagenomic virome profiling approach, Bioinformatic Application for Quantification and Labeling of Viral taxonomy (BAQLaVa), to prospectively ...

Development of an ultra-high sensitive immunoassay with plasma biomarker for differentiating Parkinson disease dementia from Parkinson disease using antibody functionalized magnetic nanoparticles

, 2017
Background: It is difficult to discriminate healthy subjects and patients with Parkinson disease (PD) or Parkinson disease dementia (PDD) by assaying plasma alpha-synuclein because the concentrations of circulating alpha-synuclein in the blood are almost

Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

Alpha-synuclein in the neurodegenerative mechanisms of Parkinson's disease and dementia with Lewy bodies

, 2012
Parkinson's disease (PD) and Dementia with Lewy bodies (DLB) are characterised by Lewy body pathology and the degeneration of midbrain-dopaminergic and cortical neurons, respectively. The mechanisms underlying the selective degeneration of these neuronal

Frequency‐ and Network‐Specific Changes in Functional Connectivity Reflect Pathophysiological Mechanisms across Parkinson's Disease Stages

Annals of Neurology, EarlyView.
Objective Parkinson's disease (PD) is increasingly conceptualized as a disorder of large‐scale brain networks, yet whether and how frequency‐specific functional connectivity reorganizes across stages remains poorly understood. In this study, we used high‐density electroencephalography (EEG) to characterize cortico‐cortical functional connectivity ...

Alpha-synuclein inclusions reduced by PIKfyve inhibition in Parkinson disease cell models

Neurobiology of Disease
Objective: Parkinson's disease (PD) pathophysiology is associated with a progressive loss of dopaminergic neurons in the substantia nigra and accumulation of insoluble inclusions of misfolded alpha-synuclein.

α-Synuclein conformational strains spread, seed and target neuronal cells differentially after injection into the olfactory bulb

Acta Neuropathologica Communications, 2019
Alpha-synuclein inclusions, the hallmarks of synucleinopathies, are suggested to spread along neuronal connections in a stereotypical pattern in the brains of patients.

Correction: Alpha-Synuclein Is a Cellular Ferrireductase

PLoS ONE, 2011
There was an error in the the second to last sentence of the Abstract: The key word "no" is missing. The correct sentence should be: "The common disease mutations associated with increased susceptibility to PD show no differences in activity or iron (II) levels."

Lipid peroxidation is essential for α-synuclein-induced cell death.

, 2015
Parkinson's disease is the second most common neurodegenerative disease and its pathogenesis is closely associated with oxidative stress. Deposition of aggregated α-synuclein (α-Syn) occurs in familial and sporadic forms of Parkinson's disease.
