Alpha-synuclein disrupted dopamine homeostasis leads to dopaminergic neuron degeneration in Caenorhabditis elegans. [PDF]

PLoS ONE, 2010
Disruption of dopamine homeostasis may lead to dopaminergic neuron degeneration, a proposed explanation for the specific vulnerability of dopaminergic neurons in Parkinson's disease. While expression of human alpha-synuclein in C.

Diagnostic value of minor salivary glands biopsy for the detection of Lewy pathology [PDF]

, 2013
The recent demonstration of the presence of Lewy pathology in the submandibular glands of Parkinson\u27s disease (PD) patients prompted us to evaluate the diagnostic performance of minor salivary gland biopsy for PD.

Alpha-Synuclein Toxicity in the Early Secretory Pathway: How it Drives Neurodegeneration in Parkinsons Disease

Frontiers in Neuroscience, 2015
Alpha-synuclein is a predominant player in the pathogenesis of Parkinson’s Disease. However, despite extensive study for two decades, its physiological and pathological mechanisms remain poorly understood.

Differential diagnostic value of total alpha-synuclein assay in the cerebrospinal fluid between Alzheimer’s disease and dementia with Lewy bodies from the prodromal stage

Alzheimer’s Research & Therapy, 2020
Background Several studies have investigated the value of alpha-synuclein assay in the cerebrospinal fluid (CSF) of Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) patients in the differential diagnosis of these two pathologies.

Functional and neuropathological changes induced by injection of distinct alpha-synuclein strains: A pilot study in non-human primates

Neurobiology of Disease, 2023
The role of alpha-synuclein in Parkinson's disease has been heavily investigated since its discovery as a component of Lewy bodies. Recent rodent data demonstrate that alpha-synuclein strain structure is critical for differential propagation and toxicity.

Characterisation of an inbred mouse strain with a deletion of the [alpha]-synuclein locus. [PDF]

, 2002
mRNA expression profiling was performed on a knock-in mouse model with a mutation in the NMDA receptor subunit NRl (N598R) that affects the receptors' function as coincidence detector. This approach was aimed at identifying downstream effects produced by

Active immunization against alpha-synuclein ameliorates the degenerative pathology and prevents demyelination in a model of multiple system atrophy. [PDF]

, 2015
BackgroundMultiple system atrophy (MSA) is a neurodegenerative disease characterized by parkinsonism, ataxia and dysautonomia. Histopathologically, the hallmark of MSA is the abnormal accumulation of alpha-synuclein (α-syn) within oligodendroglial cells,

α-Synuclein conformational strains spread, seed and target neuronal cells differentially after injection into the olfactory bulb

Acta Neuropathologica Communications, 2019
Alpha-synuclein inclusions, the hallmarks of synucleinopathies, are suggested to spread along neuronal connections in a stereotypical pattern in the brains of patients.

Loss of α-Synuclein Does Not Affect Mitochondrial Bioenergetics in Rodent Neurons. [PDF]

, 2017
Increased α-synuclein (αsyn) and mitochondrial dysfunction play central roles in the pathogenesis of Parkinson's disease (PD), and lowering αsyn is under intensive investigation as a therapeutic strategy for PD. Increased αsyn levels disrupt mitochondria

Exosomal cell-to-cell transmission of alpha synuclein oligomers

Molecular Neurodegeneration, 2012
Background Aggregation of alpha-synuclein (αsyn) and resulting cytotoxicity is a hallmark of sporadic and familial Parkinson’s disease (PD) as well as dementia with Lewy bodies, with recent evidence implicating oligomeric and pre-fibrillar forms of αsyn ...
