Upregulation of α-synuclein following immune activation: Possible trigger of Parkinson's disease

open access: yesNeurobiology of Disease, 2022
Alpha-synuclein (α-syn) has been suggested to have many functions including, vesicle transport in neurons, transcriptional regulator, modulator of immune cell maturation and response, and a role as an antimicrobial peptide.

High-Frequency Repetitive Transcranial Magnetic Stimulation Over the Left Dorsolateral Prefrontal Cortex Shortly Alleviates Fatigue in Patients With Multiple System Atrophy: A Randomized Controlled Trial

open access: yesFrontiers in Neurology, 2022
Background: Fatigue is a common symptom in patients with Multiple system atrophy (MSA), but effective treatments remain elusive. The present study aims to investigate whether high-frequency repetitive transcranial magnetic stimulation (rTMS) over the ...

Heterozygous GBA D409V and ATP13a2 mutations do not exacerbate pathological α-synuclein spread in the prodromal preformed fibrils model in young mice

open access: yesNeurobiology of Disease, 2021
Autophagic dysregulation and lysosomal impairment have been implicated in the pathogenesis of Parkinson's disease, partly due to the identification of mutations in multiple genes involved in these pathways such as GBA, SNCA, ATP13a2 (also known as PARK9),

Case Report: Progressive Asymmetric Parkinsonism Secondary to CADASIL Without Dementia

open access: yesFrontiers in Neurology, 2022
Parkinsonism is a rare phenotype of cerebral autosomal dominant arteriopathy with subcortical infarction and leukoencephalopathy (CADASIL), all of which involve cognitive decline. Normal cognition has not been reported in previous disease studies.

Dopamine signaling negatively regulates striatal phosphorylation of Cdk5 at tyrosine 15 in mice.

open access: yesFrontiers in Cellular Neuroscience, 2013
Striatal functions depend on the activity balance between the dopamine and glutamate neurotransmissions. Glutamate inputs activate cyclin-dependent kinase 5 (Cdk5), which inhibits postsynaptic dopamine signaling by phosphorylating DARPP-32 (dopamine- and

Stability of MDS-UPDRS Motor Subtypes Over Three Years in Early Parkinson's Disease

open access: yesFrontiers in Neurology, 2021
Background: Various classifications have been proposed to subtype Parkinson's disease (PD) based on their motor phenotypes. However, the stability of these subtypes has not been properly evaluated.Objective: The goal of this study was to understand the ...

Aberrant functional connectivity within the basal ganglia of patients with Parkinson's disease

open access: yesNeuroImage: Clinical, 2015
Resting state functional MRI (rs-fMRI) has been previously shown to be a promising tool for the assessment of early Parkinson's disease (PD). In order to assess whether changes within the basal ganglia network (BGN) are disease specific or relate to ...

Parkinson's disease dementia: a neural networks perspective. [PDF]

open access: yes, 2015
In the long-term, with progression of the illness, Parkinson's disease dementia affects up to 90% of patients with Parkinson's disease. With increasing life expectancy in western countries, Parkinson's disease dementia is set to become even more ...

ER Stress and Autophagic Perturbations Lead to Elevated Extracellular α-Synuclein in GBA-N370S Parkinson's iPSC-Derived Dopamine Neurons

open access: yesStem Cell Reports, 2016
Heterozygous mutations in the glucocerebrosidase gene (GBA) represent the strongest common genetic risk factor for Parkinson's disease (PD), the second most common neurodegenerative disorder.
