Somatic copy number gains of α-synuclein (SNCA) in Parkinson's disease and multiple system atrophy brains [PDF]

, 2018
The α-synuclein protein, encoded by SNCA, has a key role in the pathogenesis of Parkinson's disease and other synucleinopathies. Although usually sporadic, Parkinson's disease can result from inherited copy number variants in SNCA and other genes.

Alpha-synuclein null mutation exacerbates the phenotype of a model of Menkes disease in female mice

Frontiers in Neuroscience
Human SNCA, which encodes a-synuclein protein (SNCA), was the first gene linked to familial Parkinson’s disease (PD). Since the discovery of the genetic link of SNCA to Parkinson’s nearly three decades ago, many studies have investigated the normal ...

Normalization of Overexpressed α-Synuclein Causing Parkinson's Disease By a Moderate Gene Silencing With RNA Interference

Molecular Therapy: Nucleic Acids, 2015
The α-synuclein (SNCA) gene is a responsible gene for Parkinson's disease (PD); and not only nucleotide variations but also overexpression of SNCA appears to be involved in the pathogenesis of PD.

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

Annals of Clinical and Translational Neurology, Volume 13, Issue 9, Page 1842-1850, September 2026.
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

HMGB1 is involved in autophagy inhibition caused by SNCA/α-synuclein overexpression

, 2016
SNCA/α-synuclein and its rare mutations are considered as the culprit proteins in Parkinson disease (PD). Wild-type (WT) SNCA has been shown to impair macroautophagy in mammalian cells and in transgenic mice.

Enriched Environmental Conditions Modify the Gut Microbiome Composition and Fecal Markers of Inflammation in Parkinson’s Disease

Frontiers in Neuroscience, 2019
Recent findings suggest an implication of the gut microbiome in Parkinson’s disease (PD) patients. PD onset and progression has also been linked with various environmental factors such as physical activity, exposure to pesticides, head injury, nicotine ...

Atmospheric Aerosol Neurotoxicity and Parkinson's Disease: Mechanisms and Perspectives

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 9, September 2026.
Schematic overview of the pathways and pathological mechanisms connecting atmospheric aerosol exposure to PD. Atmospheric aerosols, including PM2.5 and nanometer/ultrafine particles loaded with metal particles, persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) and dioxins, enter the body predominantly via pulmonary ...
