The enteric nervous system (ENS), composed of neurons and enteric glial cells (EGCs), plays an essential role in the homeostasis of the gastrointestinal system. Neurons are known for their role in the transmission of information, but EGCs also have a very important role in intercellular communication.
Recent studies indicate that good communication between GECs and cells of the immune system would be crucial to maintain homeostasis within the digestive wall. Neuro-immune interactions would be critical in chronic inflammatory bowel diseases (IBD) such as Crohn's disease.
Therefore, it is important to understand the mechanisms and consequences of LT/ EGC interactions. In particular, we are studying:


  •     the impact of LT adhesion to EGCs on glial and lymphocyte phenotypes


  •     the impact of adhesion molecules on the formation of plexi


  •     the use of plexites as markers of postoperative recurrence in patients with Crohn's disease.
