This year, we want to focus on the research done at C3M on pathologies: cancer, metabolic and infectious diseases. To this end, we are proposing a tour of several research "departments" in these three areas. Visitors will be welcomed at a first stand where they will be given a brief overview of the contributions of research to medical advances. They will then move on to the cancer, metabolic and infectious disease departments. Each stand will explain what is done at C3M in relation to the pathologies in the field in a fun way, with little games. Each booth will give them a stamp which, once obtained, will give them access to a small goodie.
