Venue: Bordeaux School of Neuroscience

The normal aging process is associated with reduced performance on cognitive tasks that require one to quickly process or transform information to make a decision, including measures of speed of processing, executive cognitive function, working and relational memories. Structural and functional alterations in the brain correlate with these age-related cognitive changes, such as loss of synapses, and dysfunction of neuronal networks. It is crucial to develop new approaches that consider the whole neuroanatomical, endocrine, immunological, vascular and cellular changes impacting on cognition.

This 3-week course will cover the fundamentals of cognitive aging -including inter-individual differences, cognitive and brain reserve and risk factors- and highlight the newest functional imaging methods to study human brain function. The Faculty will share the state-of-the-art molecular, optical, computational, electrophysiological, behavioural and epidemiological approaches available for studying the aging brain in diverse model systems. The Students will learn the potential and limitations of these methods, through practical experience in a combination of lectures addressing aging in both humans and animal models and hands-on-projects. They will acquire sufficient practical experience to model, design and interpret experiments and brainstorm on novel technologies and hypotheses to explore the aging of the brain using more integrative and creative approaches.

Ignacio Fernandez Moncada est né loin d’ici, dans la ville colorée de Valparaiso, au Chili, face à l’Océan Pacifique. Il est maintenant post-doctorant au Neurocentre Magendie, dans l’équipe de Giovanni Marsicano. Faisons sa rencontre !

Des scientifiques du Laboratoire des maladies neurodégénératives (CNRS/CEA/Université Paris-Saclay) et du Neurocentre Magendie (Inserm/Université de Bordeaux) viennent de mettre en évidence le rôle déterminant que joue une voie métabolique dans les troubles de mémoire de la maladie d’Alzheimer. Leurs travaux, à paraître le 3 mars 2020 dans Cell Metabolism, montrent également qu’un apport en acide aminé particulier, sous forme de complément alimentaire, restaure la mémoire spatiale atteinte de façon précoce chez des souris modèles de la maladie. Une piste prometteuse pour atténuer la perte de mémoire liée à Alzheimer.

Revue de presse
Carvalho et al in Elife - January 2020

Vangl2 acts at the interface between actin and N-cadherin to modulate mammalian neuronal outgrowth. Steve Dos-Santos Carvalho, Maite M Moreau, Yeri Esther Hien, Michael Garcia, Nathalie Aubailly, Deborah J Henderson, Vincent Studer, Nathalie Sans, Olivier Thoumine, Mireille Montcouquiol. eLife. 2020-01-07. 9.

Here, we show that an early deletion of vangl2 in neuronal progenitors of the forebrain leads to the spatially restricted deficit of only two commissural axon bundles. Mechanistically, we show that the absence of vangl2 leads to an increase in axonal outgrowth due to a reduced turnover of N-cadherin, and a better coupling between the adhesion molecule and the dynamic actin flow in the growth cone. Our results support a model in which Vangl2 acts as a regulator of membrane protein endocytosis and junctional remodeling during growth cone exploration, thereby modulating its outgrowth.

This study benefited from a close collaboration between the groups of Montcouquiol/Sans (Neurocentre Magendie), O. Thoumine (IINS), and V. Studer (IINS), funded by the Labex BRAIN (project PCP Compass).

Offre de poste
Postdoc Position in calcium imaging (two-photon) and/or in vivo electrophysiology

The Cortical Plasticity group at the Neurocentre Magendie (Bordeaux, France) is seeking to recruit a postdoctoral researcher to join their group in 2020.

We are interested in the function of neocortical circuits and their pathophysiological modification in neurodevelopmental disorders. In particular, we study sensory information processing and perception. To address this, we will use in vivo calcium imaging (two-photon/miniscope) and electrophysiological approaches (multi-electrode/whole-cell) in behaving mice.

The project is funded for three years. We are looking for a highly motivated and proactive candidate with experience in in vivo electrophysiology and/or calcium imaging and analysis of this data. The successful candidate is expected to make significant contributions to the direction and conceptualization of the project. The appointee must have a PhD or equivalent qualification in either neuroscience, life sciences, medicine, or physics. The candidate should also have a good level of proficiency in English.

The team is based at the Neurocentre Magendie, an INSERM research institute, and member of the Bordeaux Neurocampus — a center of excellence for neuroscience research in France. The day-to-day language is English, but support would be provided for learning French if the candidate so wishes.

Interested applicants should send a cv, brief statement of research experience and interests, and names of 2-3 references to Dr. Andreas Frick: andreas.frick@inserm.fr
