A Multiscale, Systems-Level, Neuropharmacological Model of Cortico-Basal Ganglia System for Arm Reaching Under Normal, Parkinsonian, and Levodopa Medication Conditions

In order to understand the link between substantia nigra pars compacta (SNc) cell loss and Parkinson's disease (PD) symptoms, we developed a multiscale computational model that can replicate the symptoms at the behavioural level by incorporating the key ce ...

Depotentiation of associative plasticity is intact in Parkinson's disease with mild dyskinesia

Traian Popa

Objective: Depotentiation of homosynaptic plasticity of the primary motor cortex (M1) is impaired in patients with Parkinson's disease (PD) who have developed dyskinesias. In this exploratory study, we tested whether this holds true for heterosynaptic plas ...

Spatio-temporal structure of single neuron subthalamic activity identifies DBS target for anesthetized Tourette syndrome patients

Silvestro Micera, Matteo Vissani

Objective. Deep brain stimulation (DBS) of basal ganglia effectively tackles motor symptoms of movement disorders such as Tourette syndrome (TS). The precise location of target stimulation site determines the range of clinical outcome in DBS patients, and ...

Inhaling xenon ameliorates l -dopa-induced dyskinesia in experimental parkinsonism

Grégoire Courtine, Eduardo Martin Moraud, Tomislav Milekovic, Shiqi Sun

Parkinson's disease motor symptoms are treated with levodopa, but long‐term treatment leads to disabling dyskinesia. Altered synaptic transmission and maladaptive plasticity of corticostriatal glutamatergic projections play a critical role in the pathophys ...

Towards brain-on-a-chip

Yufei Ren

Since the first compartmentalized neuronal culture described by Robert B. Campenot in 1977, compartmentalized microfluidic devices have been widely used to engineer the cellular environment for cell culture. In previous research by Dr. Anja Kunze, a microf ...

alpha-Synuclein-induced dopaminergic neurodegeneration in a rat model of Parkinson's disease occurs independent of ATP13A2 (PARK9)

Bernard Schneider, Liliane Glauser, Elpida Tsika, Darren Moore, Alessandra Musso, Guillaume Daniel, Aris Nikolaos Fiser

Mutations in the ATP13A2 (PARK9) gene cause early-onset, autosomal recessive Parkinson's disease (PD) and Kufor-Rakeb syndrome. ATP13A2 mRNA is spliced into three distinct isoforms encoding a P5-type ATPase involved in regulating heavy metal transport acro ...

Mitochondrial Dysfunction in Genetic Animal Models of Parkinson's Disease

Elpida Tsika, Darren Moore, Alzbeta Trancikova

Mitochondria are highly dynamic, multifunctional organelles. Aside from their major role in energy metabolism, they are also crucial for many cellular processes including neurotransmission, synaptic maintenance, calcium homeostasis, cell death, and neurona ...

Nigrostriatal overabundance of alpha-synuclein leads to decreased vesicle density and deficits in dopamine release that correlate with reduced motor activity

Patrick Aebischer, Marco Cantoni, Graham Knott, Ralf Schneggenburger, Jean-Charles Bensadoun, Özgür Genç, Wojciech Janusz Bobela, Safa Mohanna

alpha-Synuclein (alpha-syn) is a presynaptic protein present at most nerve terminals, but its function remains largely unknown. The familial forms of Parkinson's disease associated with multiplications of the alpha-syn gene locus indicate that overabundanc ...

Rab1A Over-Expression Prevents Golgi Apparatus Fragmentation and Partially Corrects Motor Deficits in an Alpha-Synuclein Based Rat Model of Parkinson’s Disease

Patrick Aebischer, Bernard Schneider, Jean-Charles Bensadoun, Philippe Guillaume Coune

Although the overabundance of human alpha-synuclein in nigral dopaminergic neurons is considered to play a pathogenic role in Parkinson's disease (PD), it remains unclear how alpha-synuclein leads to neuronal degeneration and motor symptoms. Here, we explo ...

Modeling Parkinson's Disease in Adult Rats Using Viral Vectors as Gene Delivery Tools

Julien Dusonchet

Animal models of human pathologies remain invaluable tools for unraveling disease mechanisms and evaluating potential therapeutic strategies. For a number of diseases, the lack of a reliable animal model represents an important limiting step towards the de ...
