Role of ribosome and translation in central nervous system regeneration

Objectifs

The objectives of the project is to define how the translation and more particularly the ribosome impact the capabilities of CNS neurons to survive and/ or regenerate after an injury or during neurodegenerative diseases.

Résumé

A major challenge in Biology is to understand how genes are expressed and regulated in space and time in order to ensure cell specificity and development. Genetic expression is defined by the flow DNA-RNA-Protein. Tremendous amount of work has focused on the first step of this flow, in contrast, the last step consisting of mRNA translation into proteins is still poorly addressed. Growing body of evidence suggest that translation control and ribosome are critical for cellular life. These observations reinforce a paradigm shift: from a passive housekeeping ribosome to a direct translational regulator. We want to verify this hypothesis in the context of Central Nervous System CNS regeneration and neuroprotection in order to define new therapeutic strategies after CNS injury and neurodegenerative disease.

Méthodes

To develop this project, we will use: mouse model of CNS injury, biochemistry (western blot, immunoprecipitation), immunofluorescence and proteomics approach.
