CD4(+) T cell responses are critical for the pathogenesis of Helicobacter pylori infection. The present study evaluated role Th17 subset in H. infection induced significant expression IL-17 and IFN-gamma mouse gastric tissue. IL-23 IL-12 were increased tissue pylori-stimulated macrophages. Cell examined by intracellular staining IFN-gamma, IL-4, IL-17. Mice infected with developed a mixed Th17/Th1 response; preceded Th1 responses. Treatment mice an anti-IL-17 Ab but not control significantly...
