The patient who needs immediate assistance should not communicate directly with the researcher. Instead, they should call the doctor’s office or take other appropriate measures, such as going to the nearest emergency service.

Research interests

Neuroimmunology : interactions between two complex systems : the immune system and the central nervous system (brain and spinal cord).

Elucidation of the mechanisms whereby T lymphocytes (CD8 and CD4) attack cells of the central nervous system and thus contribute to the pathogenesis of autoimmune diseases such as multiple sclerosis.

Characterization of molecules (ligands, cytokines, intracellular proteins) expressed by the central nervous system to locally modulate immune responses.

Impact of cytokines on the functions of cells of the immune system and the central nervous system.




Multiple sclerosis: how to halt its progression?
