La reproduction est intimement liée à la balance énergétique, particulièrement chez les espèces sauvages exposées à des variations larges de leur environnement. L’objectif de cette thèse était d’étudier les mécanismes centraux qui régissent la régulation saisonnière de ces deux fonctions chez la gerboise. Nos résultats montrent une augmentation coordonnée au printemps de l’expression des gènes codant pour les neuropeptides impliqués dans la régulation de la reproduction et de la prise alimentaire, et rapportent des effets opposés de deux peptides classiquement considérés comme régulant la reproduction, Kisspeptine et RFRP-3, sur la prise alimentaire de la gerboise femelle ; un effet inhibiteur de Kisspeptine ayant lieu uniquement au printem...
