Depopulation of dense α-synuclein aggregates is associated with rescue of dopamine neuron dysfunction and death in a new Parkinson's disease model.

open access: yes, 2019
Parkinson's disease (PD) is characterized by the presence of α-synuclein aggregates known as Lewy bodies and Lewy neurites, whose formation is linked to disease development. The causal relation between α-synuclein aggregates and PD is not well understood.

Alpha-synuclein truncation and disease

open access: yesHealth, 2012
Alpha-synuclein is the major component of Lewy bodies, insoluble protein aggregates, found in patients with Parkinson’s disease, diffuse Lewy body disease, and the Lewy body variant of Alzheimer’s disease. Alpha-synuclein has been found within Lewy bodies to contain many different modifications, including nitration, phosphorylation, ubiquitination, and

Dual Hydrophilic‐Hydrophobic Core Architecture in Soy Glycinin Amyloid Fibrils Revealed by Cryo‐EM

open access: yesAdvanced Science, EarlyView.
While high‐resolution structures of animal and microbial amyloids are extensively characterized, the structural principles underlying plant‐derived amyloids remain largely unexplored. The study addresses this fundamental gap in knowledge by determining the first near‐atomic‐resolution cryo‐EM structures of amyloid fibrils derived from soy glycinin ...

Pathogenic alpha-synuclein aggregates preferentially bind to mitochondria and affect cellular respiration

open access: yesActa Neuropathologica Communications, 2019
Misfolded alpha-synuclein (αSyn) is a major constituent of Lewy bodies and Lewy neurites, which are pathological hallmarks of Parkinson’s disease (PD). The contribution of αSyn to PD is well established, but the detailed mechanism remains obscure.

Alpha-Synuclein Proximity Ligation Assay (AS-PLA) in Brain Sections to Probe for Alpha-Synuclein Oligomers

open access: yes, 2019
Alpha-synuclein oligomers are thought to be toxic mediators of Parkinson's disease and other alpha-synucleinopathies, but their histological detection in situ in diseased brain has been a challenge in the field for some time. Here we describe a method, the alpha-synuclein proximity ligation assay (AS-PLA), to detect alpha-synuclein oligomers in ...

Computational Fluid Dynamic Model Prediction of Enhanced Glymphatic Clearance in Response to Focused Ultrasound‐Mediated Blood‐Brain Barrier Opening

open access: yesAdvanced Science, EarlyView.
Focused ultrasound‐mediated blood‐brain barrier opening (FUS BBBO) for enhanced drug delivery also augments glymphatic clearance. A computational model of an arteriole‐venule pair in the brain offers insight into the underlying biotransport mechanisms responsible for this mass clearance effect.

Advancing Stem Cell Models of Alpha-Synuclein Gene Regulation in Neurodegenerative Disease

open access: yesFrontiers in Neuroscience, 2018
Alpha-synuclein (non A4 component of amyloid precursor, SNCA, NM_000345.3) plays a central role in the pathogenesis of Parkinson's disease (PD) and related Lewy body disorders such as Parkinson's disease dementia, Lewy body dementia, and multiple system ...

MRI Epicenters Differentiate Spatiotemporal Patterns of Neurodegeneration in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
A connectivity‐based MRI epicenter model identifies two Parkinson's disease subtypes: subtype 1 with infratentorial‐dominant epicenters, severe motor symptoms, and rapid progression; and subtype 2 with supratentorial‐dominant epicenters with mild progression.

Dissecting the Molecular Determinants of α‐synuclein Phase Separation and Condensate Aging: The Pivotal Role of β‐Sheet‐Rich Motifs

open access: yesAdvanced Science, EarlyView.
Through multiscale simulations and experimental approaches, the molecular determinants of α‐synuclein phase separation and condensate aging, which are linked to Parkinson's disease, are uncovered. Seven motifs are identified with high β‐sheet propensity in monomeric α‐synuclein and increasing β‐sheet tendencies during condensation and pre ...
