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

Microtubule depolymerization potentiates alpha-synuclein oligomerization [PDF]
Frontiers in Aging Neuroscience, 2010 Parkinson’s disease (PD) is associated with perturbed mitochondria function and alpha-synuclein fibrillization. We evaluated potential mechanistic links between mitochondrial dysfunction and alpha-synuclein aggregation.

Alpha synuclein and inflammaging
HeliyonThe α-synuclein protein is an established molecule in Lewy body pathology, especially Parkinson's disease (PD). While the pathological role of α-synuclein (α-syn) in PD has been well described, novel evidence may suggest that α-syn interacts with ...

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

Toxicity of extracellular alpha-synuclein is independent of intracellular alpha-synuclein
Scientific Reports, 2022 AbstractParkinson′s disease (PD) pathology progresses throughout the nervous system affecting numerous neuronal structures. It has been postulated that the progression of the pathology is based on a prion-like disease mechanism partly due to the seeding effect of endocytosed alpha-synuclein (ASYN) on the endogenous ASYN. The appearance of the pathology

Formation of toxic oligomeric alpha-synuclein species in living cells. [PDF]
PLoS 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.

Preanalytical Stability of CSF Total and Oligomeric Alpha-Synuclein
Frontiers 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.

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