Marie-Laure JOURDAIN

Dr. Marie-Laure JOURDAIN is an Associate Professor (Maître de Conférences Universitaire - Praticien Hospitalier) at the University of Reims Champagne-Ardenne, specializing in Periodontology. Her research bridges oral biology, molecular physiology, and bone pathology, with a focus on cystic fibrosis-related bone diseases, antimicrobial peptides in periodontal conditions, and biomaterial interactions with human osteoblasts/osteoclasts. She works within the EA 4691 "BIOS" research team (Biomaterials and Inflammation in Bone Sites).

• Key Research Areas: Periodontitis, CFTR gene regulation, osteoclastogenesis, sphingosine-1-phosphate signaling, strontium-substituted bioceramics
• Collaborations: Société Française de Parodontologie et Implantologie Orale (SFPIO), Collège National des Enseignants en Parodontologie (CNEP)
• Institutional Affiliation: Teaching and research at University of Reims Champagne-Ardenne, with clinical links to the Dental Care Center

Scientific Contributions include studies on gene expression in periodontitis patients, CFTR mutation impacts on bone physiology, and novel bioceramic materials for bone regeneration. Her work has been published in journals such as J Clinical Periodontology, Biochimica et Biophysica Acta, and Frontiers in Immunology.
