  • Digestive function investigation platform (motility, sensitivity, endoscopy)
  • Neurostimulation and neuronavigation systems

Activity


The works of our group, integrated to the IFRMP, are mainly dedicated to the study of eating disorders, irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD). These pathologies share common features of intestinal inflammation and dysregulation of the gut-brain axis and offer great opportunities for innovative therapeutic strategies (immunonutrition, neurostimulation). Our investigations explore the underlying mechanisms of these diseases from the molecular level to clinical trials. This broad range of research from the bench to the bedside is the result of our research strategy that brings together basic and clinical sciences, in a tight collaboration between laboratory scientists and health professionals. Our dynamic research team has an active research strategy which also drives the translation of research from the laboratory to patenting and creation of biotech companies entrepreneurship.

Main Contributions


  • Study and nutritional modulation of gut protein metabolism under inflammatory conditions: IBD, IBS and eating-disorders
  • Study of dysregulation of gut-brain axis (eatingdisorders, IBS): role of intestinal barrier in the production of autoantibodies against neuropeptides involved in eating disorders and digestive diseases
  • Development of innovative formula for intestinal inflammation-targeted nutrients or drugs and of central or peripheric neurostimulation techniques
