Eyes as Gateways for Environmental Light to the Substantia Nigra: Relevance in Parkinson’s Disease

open access: yesThe Scientific World Journal, 2014
Recent data indicates that prolonged bright light exposure of rats induces production of neuromelanin and reduction of tyrosine hydroxylase positive neurons in the substantia nigra. This effect was the result of direct light reaching the substantia nigra

LINC00323 variant is associated with increased risk of essential tremor

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Essential tremor (ET) is a common adult movement disorder, with accumulating evidence suggesting that genetic factors primarily account for ET risk. However, replication studies on the genetic variants have yielded inconsistent results. In our case–control study, we show that the LINC00323 variant, identified in a European GWAS study, is ...

Serotonergic and Dopaminergic Function in Neuropsychiatrically Asymptomatic People With HIV on Antiretroviral Therapy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with HIV (PWH) on antiretroviral therapy (ART) still experience neurocognitive dysfunction and accelerated brain volume loss. To assess whether the serotonergic and dopaminergic systems are affected, we used [11C]DASB positron emission tomography (PET) to assess presynaptic serotonergic function and [18F]FDOPA PET to measure ...

Key Connectomes and Synaptic‐Compartment‐Specific Risk Genes Drive Pathological α‐Synuclein Spreading

open access: yesAdvanced Science, EarlyView.
Utilizing a stereotaxic injection mouse model and a novel mathematical approach, this study uncovers key subnetworks that drive pathological α‐synuclein (α‐Syn) progression in Parkinson's disease (PD). Remarkably, just 2% of the strongest connections in the connectome are sufficient to predict its spread.

Longitudinal changes in free-water within the substantia nigra of Parkinson's disease.

open access: yesBrain : a journal of neurology, 2015
There is a clear need to develop non-invasive markers of substantia nigra progression in Parkinson's disease. We previously found elevated free-water levels in the substantia nigra for patients with Parkinson's disease compared with controls in single ...

Mechanical Forces Guide Axon Growth through the Nigrostriatal Pathway in an Organotypic Model

open access: yesAdvanced Science, EarlyView.
Nano‐pulling is a magnetic nanoparticle‐based technology for guiding and promoting the axon growth of induced pluripotent stem cell‐derived dopaminergic neurospheres in vitro or neural progenitors transplanted in the brain tissue. Fine control of axon guidance is essential for reconstructing neural networks and restoring functional connectivity in the ...
