The originality of my work is to develop translational approaches in psychiatric research by conducting parallel studies in humans and animal models from the same hypotheses to specify the poor known underlying mechanisms of schizophrenia, to develop effective treatments and propose biological markers.
A part of my past research strategy layed on the dopaminergic (DA) concept, drawn from my previous results and underlining the importance to consider, beyond the changes in basal DA activity, the changes in DA reactivity. Such concept has contributed to the revision of the DA hypothesis of schizophrenia.
1-I am developing translational animal models for studying schizophrenia and for the genetic at-risk state of schizophrenia. This include the STOP null mice generated by disrupting a gene involved in various interactions with cytoskeletal and leading to connectivity disorders supposed to occur in SCH and The rat with excitotoxic neonatal ventral hippocampal lesions (NVHL rats) considered as a heuristic neurodevelopmental model for studying SCH.
Animal approaches have been useful in testing standard antipsychotic drugs and developing new ones often in collaboration with the Big Pharma.
2-In Humans, my research is devoted in highlighting biological and neuropsychological markers of schizophrenia vulnerability as well as in providing a proof of concept of new therapeutic approaches adapted to psychiatric symptoms refractory to drug treatments that include peripherical brain stimulations (rTMS, tDCS). Studies incorporate magnetic resonance spectroscopy, diffusion tensor imaging, and fMRI approaches,
At the pathophysiological level, peripherical brain stimulations are used to decipher the brain alterations associated with symptoms refractory to drug treatments.
At the therapeutic levels, clinical efficacy of rTMS, tDCS, biological mechanisms underlying clinical effect and predictors of treatment outcome are studied.
