How odorant metabolizing enzymes shape odor perception?
2020
International audience; Lingering in the background of every odorant-receptor interaction is an odor metabolizing enzyme. Over the last several years, a fascinating set of studies in rodents, rabbits, insects and humans has demonstrated that these enzymes participate in the active biotransformation of odorous molecules within the perireceptor environment. These mechanisms may exert two unique effects: first, to maintain odor sensitivity by reducing receptor saturation, and second, to transform the local milieu of the odor components giving rise to unique odor percepts. This symposium will focus on the impact of odorant metabolizing enzymes (OMEs) on functional and behavioral aspects of olfa…
L'olfaction, un acteur des préférences et des choix alimentaires des enfants ?
2019
National audience; Chez l'enfant comme chez l'adulte, les choix alimentaires sont soumis à de multiples influences, qui se construisent et s'enrichissent au cours du développement. Dans un premier temps, les déterminants associés aux propriétés intrinsèques des aliments seront exposés, en explicitant le rôle des propriétés sensorielles (goût, arômes, textures), ainsi que celui de la densité énergétique de l'aliment dans l'établissement et le maintien des préférences, des consommations alimentaires et du contrôle des prises alimentaires. Dans un deuxième temps, le rôle des propriétés extrinsèques des aliments, associées à la manière de « penser » les aliments sera explicité, comme par exempl…
Smelling in the old age
2017
Several authors argued that ageing is accompanied by an impairment of olfactory abilities, i.e., the ability to perceive an odour or a taste. However, beyond this overall effect of age on chemosensory abilities, ageing is accompanied by variability in olfactory performance: the decline of odour perception with age is not uniform across odorants neither across elderly individuals. Decline in odour perception may not be inevitable to the aging individual and that factors secondary to aging, such as poor health status or cognitive decline, may contribute to deficits in odour detectability beyond the age effect per se.

Use of two odorants to control bactrocera oleae and ceratitis capitata
2020
International audience; Many insects are considered as pests because of the damage they cause to cultures. Growers and our society are waiting for environmentally safe strategies to prevent insect damages, without arming the environment and the biodiversity. Recently we discovered an innovative solution using some odorant molecules to control Drosophila suzukii behavior. Using this knowledge we started to investigate the possibility to apply this strategy to Bactrocera oleae (olive fruit fly) and Ceratitis capitata (Mediterranean fruit fly) to modify their social behavior. This new technology, which is protected by the patent n° EP19306102, could be particularly interesting to avoid infesta…
