Team PERSING

Research topics

The team's work is dedicated to basic research to unravel the genetic, molecular and cellular mechanisms at the origin of chemoperception using one of the most powerful models in neurogenetics, Drosophila melanogaster. We study various aspects of olfactory and gustatory perception and how this information is processed and integrated in the brain. We are trying to understand the impact of molecules from food on behavior: odors (mainly short fatty acids), bacterial compounds (peptidoglycan), and sugars (glucose). Concerning the central processing of this chemosensory perception, we focus on a family of amino acid transporters (SLC7) and on the interactions between glia and neurons in the primary (antennal lobe) and secondary (mushroom bodies) centers. We also seek to understand how to replace the use of insecticides, which are toxic to the ecosystem, biodiversity and human health, with food odors to protect fruit crops from insect pests. In this context, we are interested in plant-microorganism-insect communication, mainly targeting Drosophila suzukii.

To accomplish our research goals, we use a wide range of techniques from molecular biology, molecular genetics, evolutionary genetics, biochemistry, cell biology, cell and tissue culture, immunohistology, in vivo calcium imaging, neurobiology, neurophysiology, optogenetics, developmental biology, behavioral analysis. We design and develop our own specific tools.
