Solena Le Scouarnec, Jean Mérot, Romain Capoulade and Thierry Le Tourneau

In addition to our genetic investigations on familial and isolated cases of valve dystrophy, we address whether mechanical forces targeting the mitral valve are major factors leading to disease development and progression using multi-omics approaches on transgenic rats expressing the disease as well as on derived in vitro cell models.
 
  • Connect Talent - Advanced Multimodality Imaging Program and Translational Research in Chronic Cardiovascular Diseases (Romain Capoulade)

The cornerstone of genetic investigations is the precise phenotypic characterization. Emergence of a new research axis focused on the development of bio-imaging core facility and expertise in image analysis provide support to the research programs of the team, as well as offer the opportunity to develop new translational and innovative projects.
