The main focus of our research aims at furthering our understanding of the diversity of brain function by identifying and studying novel molecules which mediate synaptic transmission. Synaptic transmission is the mechanism which underlies the biochemical reactions that make brain functions and relies on the recognition of transmitters by their specific receptors.
Among the receptors that direct brain functions, the most numerous are the G protein-coupled receptors (GPCRs). We have been among the first at the end of the 80”s to clone GPCRs. Several cloned GPCRs do not bind any of the presently known transmitters, these are the "orphan" GPCRs. We expect them to bind thus far undescribed transmitters. This led us to use orphan GPCRs as targets to discover new transmitters. We were the first in 1995 to discover a novel neuropeptide through this approach. Since then, this approach has been used around the world to identify the receptors of a dozen of new transmitters.
The second phase of our studies consists in determining the biological significance of the novel transmitters. We first define the neuronal pathways in which the novel transmitter acts and then determine its effects on physiological responses and behavior. Because transmitters can have a broad spectrum of effects, this part of our approach is combined to two different approaches. The first one is to engineer strains of mice that can point at the roles of the novel transmitter in vivo. The second one is to screen for molecules that can be used in behavioral experiments in controlled conditions. More recently this approach has led us to study traditional medicines as sources of compounds that are validated in their efficacy against particular human disorders.
