Interfacing aptamer-modified nanopipettes with neuronal media and ex vivo brain tissue
Nako Nakatsuka, Anna Burdina, Annina Stuber
Aptamer-functionalized biosensors exhibit high selectivity for monitoring neurotransmitters in complex environments. We translated nanoscale aptamer-modified nanopipette sensors to detect endogenous dopamine release in vitro and ex vivo. These sensors empl ...
2023Nano-imaging trace elements at organelle levels in substantia nigra overexpressing alpha-synuclein to model Parkinson's disease
Bernard Schneider, Graham Knott, Philippe Colin
Sub-cellular trace element quantifications of nano-heterogeneities in brain tissues offer unprecedented ways to explore at elemental level the interplay between cellular compartments in neurodegenerative pathologies. We designed a quasi-correlative method ...
NATURE PUBLISHING GROUP2020Glutaredoxin 1 Downregulation in the Substantia Nigra Leads to Dopaminergic Degeneration in Mice
Background Parkinson's disease (PD) is characterized by a severe loss of the dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). Perturbation of protein thiol redox homeostasis has been shown to play a role in the dysregulation of cell ...
2020Dopaminergic modulation of motor network compensatory mechanisms in Parkinson's disease
Michael Herzog, Bogdan Draganski, Maya Anna Jastrzebowska, Renaud Marquis
The dopaminergic system has a unique gating function in the initiation and execution of movements. When the interhemispheric imbalance of dopamine inherent to the healthy brain is disrupted, as in Parkinson's disease (PD), compensatory mechanisms act to st ...
2019Dopamine induces soluble alpha-synuclein oligomers and nigrostriatal degeneration
Parkinson's disease (PD) is defined by the loss of dopaminergic neurons in the substantia nigra and the formation of Lewy body inclusions containing aggregated alpha-synuclein. Efforts to explain dopamine neuron vulnerability are hindered by the lack of do ...
Nature Publishing Group2017Parkin functionally interacts with PGC-1 proportional to to preserve mitochondria and protect dopaminergic neurons
Johan Auwerx, Patrick Aebischer, Bernard Schneider, Graham Knott, Davide D'Amico, Darren Moore, Norman Lionel Moullan, Nathalie Marie Géraldine Bernard, Lu Zheng
To understand the cause of Parkinson's disease (PD), it is important to determine the functional interactions between factors linked to the disease. Parkin is associated with autosomal recessive early-onset PD, and controls the transcription of PGC-1a, a m ...
Oxford Univ Press2017Molecular Diversity of Midbrain Development in Mouse, Human, and Stem Cells
Understanding human embryonic ventral midbrain is of major interest for Parkinson's disease. However, the cell types, their gene expression dynamics, and their relationship to commonly used rodent models remain to be defined. We performed single-cell RNA s ...
2016Elucidating the Role of Site-Specific Nitration of alpha-Synuclein in the Pathogenesis of Parkinson's Disease via Protein Semisynthesis and Mutagenesis
Hilal Lashuel, Nadine Aït Bouziad, Anass Chiki, Ritwik Burai
Parkinsons disease (PD) is characterized by the loss of dopaminergic neurons in the substantia nigra and the presence of intraneuronal inclusions consisting of aggregated and post-translationally modified a-synuclein (a-syn). Despite advances in the chemic ...
Amer Chemical Soc2015Apathy and noradrenaline: silent partners to mild cognitive impairment in Parkinson's disease?
Kerstin Preuschoff, Leyla Loued-Khenissi
Purpose of review Mild cognitive impairment (MCI) is a comorbid factor in Parkinson's disease. The aim of this review is to examine the recent neuroimaging findings in the search for Parkinson's disease MCI (PD-MCI) biomarkers to gain insight on whether MC ...
