difficile produces toxins that primarily target intestinal epithelial cells . Following toxin endocytosis and activation in the cytosol, epithelial cells undergo necrosis, which leads to loss of intestinal membrane integrity, host exposure to intestinal microorganisms and activation of the host inflammatory response.
What is the mechanism of action of the C. difficile toxin?
The toxin acts by modifying host cell GTPase proteins by glucosylation , leading to changes in cellular activities. Risk factors for C. difficile infection include antibiotic treatment, which can disrupt normal intestinal microbiota and lead to colonization of C. difficile bacteria.
