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 in hematopoiesis and immunity

Heliyon, 2019
Parkinson's disease (PD) is the second most common neurodegenerative condition and intracellular deposition of Lewy bodies in the substantia nigra (SN), which can cause dopaminergic neuronal death, is the hallmark of this syndrome. α-synuclein (syn) is a

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.

Nitrated alpha-synuclein induces the loss of dopaminergic neurons in the substantia nigra of rats. [PDF]

PLoS ONE, 2010
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]

PLoS ONE, 2009
In synucleinopathies, including Parkinson's disease, partially ubiquitylated alpha-synuclein species phosphorylated on serine 129 (P(S129)-alpha-synuclein) accumulate abnormally.

Mitochondrial localization of alpha-synuclein protein in alpha-synuclein overexpressing cells [PDF]

Neuroscience Letters, 2008
Alpha-synuclein (alpha-syn) is implicated in the pathogenesis of Parkinson's disease (PD). Mutations in alpha-syn gene or alpha-syn locus (SNCA) triplication are associated with mitochondrial abnormalities and early onset of familial PD. The goals of the present study were to examine whether alpha-syn is localized in the mitochondria of alpha-syn ...

Synapsin Condensates Recruit alpha-Synuclein

Journal of Molecular Biology, 2021
Neurotransmission relies on the tight spatial and temporal regulation of the synaptic vesicle (SV) cycle. Nerve terminals contain hundreds of SVs that form tight clusters. These clusters represent a distinct liquid phase in which one component of the phase are SVs and the other synapsin 1, a highly abundant synaptic protein.

Anti-α-synuclein c-terminal antibodies block PFF uptake and accumulation of phospho-synuclein in preclinical models of Parkinson's disease

Neurobiology of Disease, 2023
Parkinson's disease (PD), a neurodegenerative disease affecting dopaminergic (DA) neurons, is characterized by decline of motor function and cognition. Dopaminergic cell loss is associated with accumulation of toxic alpha synuclein aggregates.

Transcriptional regulation of the beta-synuclein 5'-promoter metal response element by metal transcription factor-1. [PDF]

PLoS ONE, 2011
The progression of many human neurodegenerative disorders is associated with an accumulation of alpha-synuclein. Alpha-synuclein belongs to the homologous synuclein family, which includes beta-synuclein.
