Fatty Acid Smell, Anesthesia, and Use on Fruit Crops
2023
Odors convey important information to select a sex partner, to find a food source, or to detect a danger. Among those some volatile molecules have been shown to cause a reversible anesthesia. However, their mode of action appears still largely mysterious. Here we describe a novel property of Olfactory Receptor 47b (OR47b), on olfactory sensory neurons (OSNs) expressing male-specific transcription factor FruM. We found some interesting properties of a fatty acid that can be present on food sources and oviposition sites for Drosophilid species. We show that OR47b neurons projecting to VA1v glomerulus are sensitive to this odor, and that this influences Drosophila behavior causing a strong ave…

Postnatal odorant exposure induces peripheral olfactory plasticity
2013
Olfactory sensory neurons (OSNs) form an interface between the environment and the brain, converting chemical information (odorants) into electrical signals and sending these signals to the brain. Little is known about the consequences of long term odorant exposure on OSNs. Our goal is to understand the anatomical, molecular and physiological effects of odorant exposure at the cellular level and more precisely in the context of an early postnatal olfactory exposure. We focus our work on specific populations of OSNs expressing particular ORs using gene-targeted mice. MOR23-GFP mice were exposed daily to Lyral and anatomical, molecular and physiological properties of these neurons were analyz…
Fos mapping of brain activation induced by the mammary pheromone in the newborn rabbit
2010
The female European rabbit, Oryctolagus cuniculus, displays a surprising maternal behaviour. Indeed, she comes into the nest only once per day and for a very brief period (3-4 minutes), almost exclusively to nurse. A pheromonal signal identified as the 2-methylbut-2-enal and named the mammary pheromone (MP) is emitted in milk by all lactating rabbit females. This chemosensory cue induces typical head-searching and oral-seizing movements in newborn rabbits usually involved in the localisation of the nipples. The MP therefore appears as a biological signal important for sucking, survival and growth in pups. To date, only few data are available regarding the neuronal substrate which sustains t…
