Molecular architecture of the developing mouse brain

Gioele La Manno, Alex Russell Lederer, Irina Khven

The mammalian brain develops through a complex interplay of spatial cues generated by diffusible morphogens, cell-cell interactions and intrinsic genetic programs that result in probably more than a thousand distinct cell types. A complete understanding of ...

Parkinson mice show functional and molecular changes in the gut long before motoric disease onset

Hilal Lashuel, Yang Liu

Background: There is increasing evidence that Parkinson's disease (PD) might start in the gut, thus involving and compromising also the enteric nervous system (ENS). At the clinical onset of the disease the majority of dopaminergic neurons in the midbrain ...

Nano-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 ...

Glutaredoxin 1 Downregulation in the Substantia Nigra Leads to Dopaminergic Degeneration in Mice

Bernard Schneider

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 ...

Dopaminergic neurodegeneration induced by Parkinson's disease-linked G2019S LRRK2 is dependent on kinase and GTPase activity

Elpida Tsika, Darren Moore, Xi Chen

Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common cause of late-onset, autosomal-dominant familial Parkinson's disease (PD). LRRK2 functions as both a kinase and GTPase, and PD-linked mutations are known to influence both enzymatic acti ...

Dopaminergic 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 ...

Dopamine induces soluble alpha-synuclein oligomers and nigrostriatal degeneration

Elpida Tsika

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 ...

Parkin 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 ...

Astrocytes: New Targets for the Treatment of Neurodegenerative Diseases

Pierre Magistretti, Sylvain Eric Lengacher, Charles Léonard Finsterwald

The causes of neurodegenerative disorders are multiple, and for most of them a mechanistic understanding is still lacking. However, neurodegenerative diseases such as Alzheimer disease (AD), amyotrophic lateral sclerosis (ALS) and Parkinson disease (PD) al ...

Lack of additive role of ageing in nigrostriatal neurodegeneration triggered by alpha-synuclein overexpression

Grégoire Courtine, Laetitia Danielle Philippine Baud, Isabel Laura Vollenweider

Introduction: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons as well as the presence of proteinaceous inclusions named Lewy bodies. alpha synuclein (alpha-syn) is a major constituent o ...
