Ontogenèse des neurones à kisspeptine chez le rat : neurogénèse et cartographie spatio-temporelle de kisspeptine de l'embryogénèse à l'âge adulte / Ontogenesis of kisspeptin neurons in rat : neurogenesis and spatio-temporal cartographie of kisspeptin neurone from embryogenesis to adulthood

Crossard, Elodie 14 December 2011 (has links)
Le kisspeptine (kp) est un peptide, dérivé du gène kiss-1, jouant un rôle majeur dans le contrôle central de la fonction de reproduction en régulant la sécrétion du GnRH chez l’adulte mais également au cours du développement. Les neurones exprimant kiss-1 sont situés dans la région rostrale périventriculaire du 3ème ventricule (RP3V) et le noyau arqué (ARC). L’expression de kiss-1 est hautement régulée par les stéroides sexuels, positivement dans RP3V et négativement dans ARC. Ces deux populations de neurones à kp semblent avoir des rôles différents. Les neurones à kp du RP3V seraient impliqués dans la genèse du pic préovulatoire et ceux de l’ARC dans la régulation de la sécrétion pulsatile de GnRH.L’objectif de la thèse était de déterminer la période de neurogenèse des neurones à kp ainsi que les variations de l’expression de kiss-1 et de kp dans ces deux régions au cours des différentes phases du développement chez le rat mâle et femelle.Nos résultats ont permis de cibler les périodes clés de l’ontogenèse des neurones à kp en montrant 1) que les neurones à kp de l’ARC naissent sur une période étendue à partir du jour embryonnaire (E)12,5; 2) l’existence d’une sous- expression péri-natale du kp dans l’ARC indépendante du sexe; 3) la mise en place, en période néonatale, de différences sexuelles dans les niveaux d’expression et la distribution neuroanatomique du kp; 4) l’existence de régulations péri-pubertaires de kp, dépendantes du sexe et de la région ; 5) la présence de fibres à kp dans des régions hypothalamiques suggère un rôle de kp au-delà de la fonction de reproduction. / Kisspeptin (kp) is a neuropeptide, derived from the kiss-1 gene, which plays a key role in the central control of reproduction by regulating GnRH secretion in adult but also during development. Cells which express kiss-1 are localized in two distincts hypothalamic regions: the rostral peri-ventricular third ventricule area (RP3V) and the arcuate nucleus (ARC). Kiss-1 expression is highly regulated by sex steroids: positively in the RP3V and negatively in the ARC. RP3V kp neurons have been implicated in the pre-ovulatory GnRH surge whereas ARC kp neurons may predominantly act on GnRH secretion pulsatility. The aim of this PhD work was to determine the neurogenesis period of kp neurons and changes of kiss-1 and kp expression in both regions during different stages of development in rats. Our results highlight key periods of kp neurons ontogenesis and show that: 1) ARC kp neurons are born during an extended embryonic neurogenesis period starting at embryonic day (E) 12,5; 2) a sex independent down-regulation of kp occurs during peri-natal period; 3) sex difference in the expression level and neuroanatomique distribution of kp establishes during neo-natal period; 4) kp was regulated during peri-pubertal period in sex and region dependant manner; 5) kp-ir fibers are detected throughout the septo-hypothalamic continuum suggesting that kp could be implicated in other functions than reproductive function.
