Primary skin fibroblasts as a model of Parkinson's disease [PDF]

, 2012
Parkinson's disease is the second most frequent neurodegenerative disorder. While most cases occur sporadic mutations in a growing number of genes including Parkin (PARK2) and PINK1 (PARK6) have been associated with the disease.

Chemical Approaches for Array Based Detection of Amyloids

Advanced Sensor Research, EarlyView.
Amyloids are protein aggregates with both pathological and functional roles. Their detection is challenged by structural polymorphism, isoform diversity, and dynamic aggregation behavior. This review presents chemical array‐based sensing strategies that address these complexities, emphasizing fluorescence and colorimetric methods, alongside ...

Assessment of the direct and indirect effects of MPP+ and dopamine on the human proteasome: implications for Parkinson's disease aetiology [PDF]

, 2008
Mitochondrial impairment, glutathione depletion and oxidative stress have been implicated in the pathogenesis of Parkinson’s disease (PD), linked recently to proteasomal dysfunction.

The GLP1R Agonist Semaglutide Inhibits Reactive Astrocytes and Enhances the Efficacy of Neural Stem Cell Transplantation Therapy in Parkinson's Disease Mice

Advanced Science, EarlyView.
Compared to transplantation of neural stem cells (NSCs) alone, the combined treatment of NSCs with semaglutide more effectively improves motor dysfunction in Parkinson's disease (PD) mice. This synergistic effect may result from semaglutide's ability to suppress microglial activation, thereby preventing the transformation of resting astrocytes into ...

Alpha-Synuclein Toxicity in the Early Secretory Pathway: How it Drives Neurodegeneration in Parkinsons Disease

Frontiers in Neuroscience, 2015
Alpha-synuclein is a predominant player in the pathogenesis of Parkinson’s Disease. However, despite extensive study for two decades, its physiological and pathological mechanisms remain poorly understood.

Loss of vesicular dopamine release precedes tauopathy in degenerative dopaminergic neurons in a Drosophila model expressing human tau. [PDF]

, 2013
While a number of genome-wide association studies have identified microtubule-associated protein tau as a strong risk factor for Parkinson's disease (PD), little is known about the mechanism through which human tau can predispose an individual to this ...

A Prion‐Like Domain in EBV EBNA1 Promotes Phase Separation and Enables SRRM1 Splicing

Advanced Science, EarlyView.
This study discoveries that EBV EBNA1 behaves as a prion‐like protein, verified using cell‐based assays and the Saccharomyces cerevisiae Sup35p prion identification system. The prion‐like domain of EBNA1 drives liquid–liquid phase separation. EBNA1 interacts with the splicing factor SRSF1 to regulate the expression of the SRRM1 splicing isoforms ...

Differential diagnostic value of total alpha-synuclein assay in the cerebrospinal fluid between Alzheimer’s disease and dementia with Lewy bodies from the prodromal stage

Alzheimer’s Research & Therapy, 2020
Background Several studies have investigated the value of alpha-synuclein assay in the cerebrospinal fluid (CSF) of Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) patients in the differential diagnosis of these two pathologies.

Alpha-synuclein is a DNA binding protein that modulates DNA repair with implications for Lewy body disorders

Scientific Reports, 2019
Alpha-synuclein is a presynaptic protein that forms abnormal cytoplasmic aggregates in Lewy body disorders. Although nuclear alpha-synuclein localization has been described, its function in the nucleus is not well understood.
