Lysosomal dysfunction increases exosome-mediated alpha-synuclein release and transmission
Alpha-synuclein aggregation plays a central role in Parkinson's disease pathology. Direct transmission of alpha-synuclein from pathologically affected to healthy unaffected neurons may be important in the anatomical spread of the disease through the ...

Inhibition of calpain prevents manganese-induced cell injury and alpha-synuclein oligomerization in organotypic brain slice cultures. [PDF]
Overexposure to manganese has been known to promote alpha-synuclein oligomerization and enhance cellular toxicity. However, the exact mechanism of Mn-induced alpha-synuclein oligomerization is unclear.

Alpha-synuclein suppression by targeted small interfering RNA in the primate substantia nigra. [PDF]
The protein alpha-synuclein is involved in the pathogenesis of Parkinson's disease and other neurodegenerative disorders. Its toxic potential appears to be enhanced by increased protein expression, providing a compelling rationale for therapeutic ...

Preanalytical Stability of CSF Total and Oligomeric Alpha-Synuclein
Background: The role of cerebrospinal fluid (CSF) alpha-synuclein as a potential biomarker has been challenged mainly due to variable preanalytical measures between laboratories.

Formation of toxic oligomeric alpha-synuclein species in living cells. [PDF]
Misfolding, oligomerization, and fibrillization of alpha-synuclein are thought to be central events in the onset and progression of Parkinson's disease (PD) and related disorders.

The HSP70 molecular chaperone is not beneficial in a mouse model of alpha-synucleinopathy. [PDF]
BACKGROUND: Aggregation and misfolded alpha-synuclein is thought to be central in the pathogenesis of Parkinson's disease (PD). Heat-shock proteins (HSPs) that are involved in refolding and degradation processes could lower the aggregate load of alpha ...

Nitrated alpha-synuclein induces the loss of dopaminergic neurons in the substantia nigra of rats. [PDF]
BACKGROUND: The pathology of Parkinson's disease (PD) is characterized by the degeneration of the nigrostriatal dopaminergic pathway, as well as the formation of intraneuronal inclusions known as Lewy bodies and Lewy neurites in the substantia nigra ...

Parkin deficiency delays motor decline and disease manifestation in a mouse model of synucleinopathy. [PDF]
In synucleinopathies, including Parkinson's disease, partially ubiquitylated alpha-synuclein species phosphorylated on serine 129 (P(S129)-alpha-synuclein) accumulate abnormally.
