Neurological and psychiatric diseases

Research Theme

Notre recherche est centrée sur l’étude des bases moléculaires et de la physiopathologie de différentes affections neurodégénératives. Les approches génétiques visent à cartographier des gènes responsables ou des facteurs de susceptibilité génétique de ces maladies (maladies de Parkinson et d’Alzheimer, démences fronto-temporales, ataxies cérébelleuses, paraplégies spastiques et dystonies). Ces avancées génétiques permettent d’établir la fréquence relative de chaque gène, son spectre mutationnel et d’établir des corrélations phénotype-génotype ainsi que d’identifier des biomarqueurs grâce au matériel biologique collecté à travers des réseaux nationaux et internationaux. Ce matériel inclut des données phénotypes précises et le cas échéant, le prélèvement biologique et tissulaire.

Project:

We are investigating how mutations responsible for neurodegenerative diseases can affect the function of subcellular organelles. Our research is currently focused on lysosomes and endoplasmic reticulum. We aim to understand how alterations of these cellular compartments can contribute to the neuronal death in order to identify putative therapeutic targets to delay the progression of neurodegeneration. To answer these questions we use a variety of models (cultured cells, animal models, but also induced pluripotent stem cells), imaging techniques and biochemical approaches.
