The gastric bacterial pathogenHelicobacter pyloripersistently colonizes the gastric mucosa of humans and plays a critical role in the development of gastritis, peptic ulceration and gastric adenocarcinoma. Consequently, the eradication ofH. pylorimight contribute to the prevention ofH. pylori-associated gastric diseases. In this study, a multi-epitope vaccine CTB-UE (CUE) was displayed on the surface of non-genetically modifiedLactococcus lactisparticles (GEM) to enhance immunogenicity. This particulate vaccine CUE-GEM induced serum and mucosal specific antibody responses against nativeH. pyloriurease and provided potent protection to eliminateH. pyloricolonization and relieve gastritis in anH. pylori-infected BALB/c mouse model. The immuno-protective mechanisms are highly associated with CD4+Th cell-mediated and humoral immunity, especially local immunity. There might be two main aspects of this association. One aspect is related to the suppression of urease activity by promotion of the production of specific mucosal neutralizing antibody. The other aspect is correlated with alleviating gastritis by regulating the gastric pro-inflammatory cytokine profile, especially IFN-γ and IL-17. These results demonstrated that conjugating antigen vaccines with GEM particles could lead to promising oral therapeutic vaccine formulations againstH. pyloriinfection.
