Parkinson disease (PD) is the second most common neurodegenerative disorder after Alzheimer disease (AD). There is considerable consensus that the increased production and/or aggregation of alpha-synuclein (alpha-syn) plays a central role in the pathogenes ...

Alpha-synuclein is linked to both sporadic and familial forms of Parkinson's disease. The protein represents the major component of Lewy bodies – one of the hallmarks of the disease. Additionally, several point mutations and locus multiplications in the ge ...
In synucleinopathies, including Parkinson's disease, partially ubiquitylated alpha-synuclein species phosphorylated on serine 129 (P(S129)-alpha-synuclein) accumulate abnormally. Parkin, an ubiquitin-protein ligase that is dysfunctional in autosomal recess ...
Background: Missense mutations and multiplications of the alpha-synuclein gene cause autosomal dominant familial Parkinson's disease (PD). alpha-Synuclein protein is also a major component of Lewy bodies, the hallmark pathological inclusions of PD. Therefo ...
Studies in yeast are providing critical insights into the mechanisms of neurodegeneration in Parkinson's disease (PD). A recent study shows that disruption of vesicular trafficking between the endoplasmic reticulum (ER) and the Golgi, caused by the overexp ...
Parkinson's disease (PD) is characterized by the degeneration of dopamineric neurons of the substantia nigra pars compacta projecting to the striatum, and by the deposition of cytoplasmic protein inclusions. It is further defined by the persistent presence ...
α-Synuclein aggregates in Lewy bodies and plays a central role in the pathogenesis of a group of neurodegenerative disorders, known as "Synucleinopathies", including Parkinson's disease. Parkin mutations result in loss of parkin E3-ubiquitin ligase activit ...
We explored the relationship between ubiquitin proteasome system (UPS) and lysosomal markers and the formation of alpha-synuclein (alpha-syn) inclusions in nigral neurons in Parkinson disease (PD). Lysosome Associated Membrane Protein 1(LAMP1), Cathepsin D ...
Missense mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are the most common causes of both familial and sporadic forms of Parkinson disease and are also associated with diverse pathological alterations. The mechanisms whereby LRRK2 mutations ca ...
Parkinson disease (PD) is characterized by dopaminergic neurodegeneration and intracellular inclusions of alpha-synuclein amyloid fibers, which are stable and difficult to dissolve. Whether inclusions are neuroprotective or pathological remains controversi ...
