Nadia Soussi-Yanicostas, PhD, HDR, and Research director at CNRS. She leads a team on Neurodevelopment & neurodevelpmental disorders in zebrafish at Université de Paris, in the INSERM unit U1141 at Robert Debré Hospital in Paris, France. In my team, we use zebrafish embryos as in vivo tools to better understand the interactions between neurons and microglial cells in different disease contexts, such as epilepsy and childhood encephalopathy, and following environmental insults, such as pesticide poisoning. Specifically, we use a multidisciplinary approach, combining zebrafish mutants, transgenic technologies, in vivo calcium imaging, electrophysiology, behavioural studies, and classic molecular biology methods of protein and RNA analysis, to: (i) precisely characterize the spectrum of microglia activities induced by different types of neuron dysfunctions resulting from either disease or poisoning, and (ii) better understanding the consequences of these microglia activities (neuro-inflammation and/or neuro-protection) on subsequent neuron physiology. Currently, the research activity of my team is focused on two main research projects. The first aims at investigating the activity of microglia in different genetic epilepsy contexts in zebrafish (using mutant lines scn1Lab-/-, depdc5-/-, gabra1-/- and gabrg2-/-, four genes that have been found mutated in human Dravet syndrome childhood epilepsy) and also better understand the consequences of this microglia activity on subsequent brain functioning and neuron excitability. In line with this research theme, using diisopropylfluorophodphate (DFP), a mildly toxic organophosphorus compound analogous to warfare agents Sarin and Soman, we are also investigating the mechanism underlying the epileptogenic effect of organophosphorus and seek identifying effective countermeasures. Our second project is in line with the recent demonstration in our laboratory that succinate dehydrogenase inhibitor (SDHI) molecules, the most widely used fungicides in agriculture practices today, are not fungus-specific and efficient inhibit SDH activity in honey bees, lumbrics and human cells. In our team we are studying the role of three SDHIs, which has never been estimated in in vivo models, on neurodevelopment and neurobehavior.
Nadia Soussi-Yanicostas is a CNRS Research Director (DR) and the leader of the Microglia and Epilepsy group at the UMR 1141. She has long-standing expertise in development, neurosciences, human genetics, and zebrafish models of human diseases including epilepsy. He also has skills in preclinical studies in animal models of brain disorders such as tauopathies and epilepsy. She has published 57 papers in international peer-reviewed journals.
