title: Mycobacterium avium subspecies paratuberculosis infects and multiplies in enteric glial cells.
abstract: OBJECTIVE
  To establish the role of enteric glial cells during infection with Mycobacterium avium subspecies paratuberculosis (MAP) in Crohn's disease.
  
  
  METHODS
  In order to establish the role of enteric glial cells during infection with M. avium subspecies paratuberculosis (MAP) in Crohn's disease, Map adhesion experiments on enteric glial cells were performed as well as expression analysis of Map sigma factors during infection.
  
  
  RESULTS
  In this study, for the first time, we found a high affinity of MAP to enteric glial cells and we analyzed the expression of MAP sigma factors under different conditions of growth.
  
  
  CONCLUSIONS
  The fact that Map showed a high affinity to the glial cells raises concerns about the complicated etiology of the Crohn's disease. Elucidation of the mechanisms whereby inflammation alters enteric neural control of gut functions may lead to novel treatments for Crohn's disease.
