  • Title: Experimental model of Helicobacter pylori infection.
    Author: Del Giudice G, Ghiara P, Rappuoli R.
    Journal: Ital J Gastroenterol Hepatol; 1998 Oct; 30 Suppl 3():S261-3. PubMed ID: 10077750.
    Abstract:
    Critical issues in the development of a vaccine against Helicobacter pylori are represented by the definition of molecules important in the pathogenesis of the infection, by the availability of an animal model reproducing several aspects of the human infection, and lastly by the availability of powerful adjuvants allowing strong protection after mucosal delivery of the antigens. A mouse model of Helicobacter pylori infection was established in our laboratories. Vaccination of these animals with Helicobacter pylori antigens, such as VacA, CagA, etc., induced protection, both prophylactic and therapeutic, when antigens were administered orally together with fully non toxic mutants of Escherichia coli heat-labile enterotoxin, as mucosal adjuvants. This experimental mouse model allows the study of the pathogenesis of Helicobacter pylori infection and the development of vaccines.
