Intérêts de recherche

  • Maturation post-testiculaire des spermatozoïdes
  • Stress oxydatif et qualité du sperme
  • Épigénétique des gamètes mâles

Les activités de recherche, au sein de l’équipe MePTI (Mechanisms of Post-Testicular Infertility) sont centrées sur la maturation épididymaire des gamètes mâles. À l’aide de modèles murins, génétiquement modifiés pour étudier la fonction des protéines cibles, différentes questions biologiques sont abordées:
1- Quel est l’impact du stress oxydant épididymaire sur le patrimoine génétique et épigénétique des gamètes ?
2- Comment une dyslipidémie modifie-t-elle la physiologie de l’épididymaire, la composition et la fonction des gamètes ?
3- Comment l’épididyme répond-il au défi immunitaire représenté par la protection des spermatozoïdes contre une réaction auto-immunie tout en protégeant l’organe et les gamètes des micro-organismes infectieux ?
Ces thèmes de recherche sont abordés à l’aide de différentes techniques et technologies: études biologiques classiques des gamètes mâles (motilité, morphologie, viabilité, réaction de l’acrosomique, fragmentation de l’ADN pvia des analyses sur une plateforme semi-automatisée), niveaud’oxydation de l’ADN par immunofluorescence et microscopie confocale, immunoprécipitation à ADN oxydé ( Oxidip) et séquençage nouvelle génération, cytométrie en flux et tri cellulaire, biologie moléculaire (qRT-PCR, western-blot…).
