Chronic Intestinal Pseudo-Obstruction Syndrome (CIPO) is a rare gastrointestinal motility disorder. CIPO evolves through iterative flare-ups that can be triggered by viral or bacterial infections, psychological stress, or malnutrition. All of these factors are associated with dysbiosis of the intestinal microbiota (IM). Many studies have associated visceral pain with dysbiosis of the IM, particularly in the context of irritable bowel syndrome (IBS), a painful pathology associated with transit disorders. The team in Dr. CĂ©nac's laboratory has demonstrated the analgesic effect of a bacterial lipid produced by an intestinal bacterium in the context of IBS. The study hypothesize that CIPO patients have a taxonomic and functional dysbiosis of the IM responsible for hyperactivation of sensory neurons inducing visceral pain.
