Core Tip

Core Tip:Helicobacter pylori (H. pylori) infection seems to modulate the immune response triggered by inflammatory bowel disease in a way that makes it less aggressive. The virulence factors of H. pylori, as well as the mechanisms that allow it to remain in the stomach environment, appear to change the intestinal microenvironment and modulate the local immune response, contributing to a disease with milder symptoms and less tissue damage.
