Neural connectivity predicts spreading of alpha-synuclein pathology in fibril-injected mouse models: Involvement of retrograde and anterograde axonal propagation [PDF]

open access: yesNeurobiology of Disease, 2020
In Parkinson's disease, some of the first alpha-synuclein aggregates appear in the olfactory system and the dorsal motor nucleus of the vagus nerve before spreading to connected brain regions.

C. elegans model identifies genetic modifiers of alpha-synuclein inclusion formation during aging. [PDF]

open access: yesPLoS Genetics, 2008
Inclusions in the brain containing alpha-synuclein are the pathological hallmark of Parkinson's disease, but how these inclusions are formed and how this links to disease is poorly understood. We have developed a C.

A split biotin ligase approach reveals proteins associated with oligomeric alpha-synuclein during aggregation [PDF]

open access: yesScientific Reports
Lewy pathology can form over decades in patients with Lewy body diseases, but the causal cellular mechanisms associated with this process remain unclear.

In-cell NMR characterization of the secondary structure populations of a disordered conformation of α-Synuclein within E. coli cells [PDF]

open access: yes, 2013
α-Synuclein is a small protein strongly implicated in the pathogenesis of Parkinson’s disease and related neurodegenerative disorders. We report here the use of in-cell NMR spectroscopy to observe directly the structure and dynamics of this protein ...

Inhibition of calpain prevents manganese-induced cell injury and alpha-synuclein oligomerization in organotypic brain slice cultures. [PDF]

open access: yesPLoS ONE, 2015
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]

open access: yesPLoS ONE, 2010
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

open access: yesFrontiers in Aging Neuroscience, 2021
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]

open access: yesPLoS ONE, 2008
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.

Toward a Disease-Modifying Therapy of Alpha-Synucleinopathies: New Molecules and New Approaches Came into the Limelight

open access: yesMolecules, 2021
The accumulation of the various products of alpha-synuclein aggregation has been associated with the etiology and pathogenesis of several neurodegenerative conditions, including both familial and sporadic forms of Parkinson’s disease (PD) and dementia ...

The HSP70 molecular chaperone is not beneficial in a mouse model of alpha-synucleinopathy. [PDF]

open access: yesPLoS ONE, 2010
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 ...
