A Systematic Comparison of Alpha‐Synuclein Seed Amplification Assays for Increasing Reproducibility
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Seed amplification assays (SAAs) enable ultrasensitive detection of misfolded α‐synuclein across biofluids and tissues. Yet, heterogeneity in protocols limits cross‐study comparability and clinical translation. Here, we review α‐synuclein SAA methods and their performance across various biological matrices.

Lipid peroxidation is essential for α-synuclein-induced cell death. [PDF]
, 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.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal state for Lewy body disorders and exhibits biological heterogeneity that may influence clinical expression and progression. We examined clinical features in individuals with iRBD and biomarker‐defined synucleinopathy.

Translational Neurodegeneration, 2020 Background α-Synuclein is a small soluble protein, whose physiological function in the healthy brain is poorly understood. Intracellular inclusions of α-synuclein, referred to as Lewy bodies (LBs), are pathological hallmarks of α-synucleinopathies, such ...

Sideroflexin 3 is an α-synuclein-dependent mitochondrial protein that regulates synaptic morphology [PDF]
, 2017 α-Synuclein plays a central role in Parkinson's disease, where it contributes to the vulnerability of synapses to degeneration. However, the downstream mechanisms through which α-synuclein controls synaptic stability and degeneration are not fully ...

Advanced Healthcare Materials, EarlyView.Lysosome‐targeted acidic nanoparticles based on a biodegradable poly(ethylene tetrafluorosuccinate‐co‐succinate) copolymer are engineered to restore impaired lysosomal acidification through pH‐responsive intracellular degradation. Localized acid release enhances autophagic proteolysis, reduces α‐synuclein accumulation, and preserves dopaminergic neuron

Neuroprotective function of Omi to α-synuclein-induced neurotoxicity
Neurobiology of Disease, 2020 Astract: The main pathological hallmark of Parkinson's disease (PD) is the presence of Lewy bodies, which mainly consist of aggregated α-synuclein. Based on the neurotoxicity of oligomeric α-synuclein and its significance in the aetiology of PD, there ...

Advanced Healthcare Materials, EarlyView.This review summarizes the roles of key central nervous system cell types, the extracellular matrix, and the blood‐brain barrier in neuroinflammation, and their integration into diverse 3D culture systems. It examines major incorporation strategies, including direct co‐culture, hydrogel encapsulation, transwell migration assays, and bioprinting ...

Cell Reports, 2016 Ample evidence suggests that α-synuclein is released from cells and propagated from one area of the brain to others via cell-to-cell transmission. In terms of their prion-like behavior, α-synuclein propagation plays key roles in the pathogenesis and ...
