The E46K mutation modulates α-synuclein prion replication in transgenic mice

PLoS Pathogens, 2022
In multiple system atrophy (MSA), the α-synuclein protein misfolds into a self-templating prion conformation that spreads throughout the brain, leading to progressive neurodegeneration.

Plasma and Serum Alpha-Synuclein as a Biomarker of Diagnosis in Patients With Parkinson's Disease

Frontiers in Neurology, 2020
Background: Parkinson's disease (PD) is the second most common neurodegenerative disease, and α-synuclein plays a critical role in the pathogenesis of PD.

Spatiotemporal Control of Formation of Dynamic Protein Fiber Assemblies via Photophysical Effects of a Focused Laser Beam

Advanced Science, EarlyView.
Tightly focused laser irradiation can accumulate tubulin proteins at/around the laser focus, which leads to the formation of highly ordered microtubule assemblies. The assemblies can exhibit various dynamic behaviors such as radial motion, bundling, and flagella‐like rotation with motor protein and chemical energy, highlighting as a unique tool for ...

Glycogen synthase kinase 3 β activity is essential for Polo-like kinase 2- and Leucine-rich repeat kinase 2-mediated regulation of α-synuclein

Neurobiology of Disease, 2020
Parkinson's disease (PD) is a currently incurable disease and the number of patients is expected to increase due to the extended human lifespan. α-Synuclein is a pathological hallmark of PD and variations and triplications of the gene encoding α ...

PRMT9 Aggravated Dopaminergic Neurodegeneration in Parkinson's Disease Model by Facilitating the Degradation of DUSP26 and Inducing Mitochondrial Dysfunction

Advanced Science, EarlyView.
In the pathological state of PD induced by MPP+, the upregulated PRMT9 in dopaminergic neurons translocates into mitochondrion and interacts with DUSP26 and catalyzes its arginine methylation, leading to the ubiquitin‐proteasomal degradation of DUSP26 mediated by Trim32.

TDP‐43 Aggregation: The Healthy‐Toxic Balance of the Prion‐Like Domain

Advanced Science, EarlyView.
TDP‐43 function relies on a delicate balance between reversible phase‐separated states and irreversible aggregation. Under physiological conditions, TDP‐43 forms dynamic droplets and oligomers that support normal cellular functions. In pathological contexts, this balance shifts toward aberrant aggregation, leading to toxic species.

Elevated plasma levels of alpha-synuclein are dispensable for Parkinson’s disease pathology

npj Parkinson's Disease
Although α-synuclein levels are elevated in the blood plasma of Parkinson’s disease (PD) patients, it remains unclear whether blood-derived α-synuclein directly contributes to PD.

Intracellular Catalytic Photooxygenation of α‐Synuclein Amyloid

ChemistryEurope
The amyloid aggregation of α‐synuclein is a central pathological hallmark of various synucleinopathies, including Parkinson disease. Consequently, developing strategies to eliminate α‐synuclein amyloids represents a promising therapeutic approach.
