Core Tip |
Helicobacter pylori (H. pylori) related diseases are commonly associated with cagA+ strains, although seropositivity against CagA varies among different studies. In this prospective study, we evaluated potential factors related to the H. pylori CagA-immune response. We show that anti-CagA-IgG seropositivity was strongly associated with histopathological and inflammatory factors. Most importantly, we identified H. pylori vacA polymorphism as one of the main determinants of immune response to CagA and inflammatory potential of H. pylori strains ex vivo and in vitro. Our data support the crucial role of bacterial factors that co-determine the complex interaction with H. pylori and define the immune and clinical phenotypes of the infection. |
