title: Inflammation, Immunity, and Vaccines for Helicobacter pylori Infection.
abstract: During the last year, a variety of studies have been published that increases our understanding of the basic mechanisms of immunity and inflammation in Helicobacter pylori infection and progression to gastric cancer. Innate immune regulation and epithelial cell response were covered by several studies that contribute with new insights in the host response to H. pylori infection. Also, the adaptive immune response to H. pylori and particularly the role of IL-22 have been addressed in some studies. These advances may improve vaccine development where new strategies have been published. Two major studies analyzed H. pylori genomes of 39 worldwide strains and looked at the protein profiles. In addition, multi-epitope vaccines for therapeutic use have been investigated. Studies on different adjuvants and delivery systems have also given us new insights. This review presents articles from the last year that reveal detailed insight into immunity and regulation of inflammation, the contribution of immune cells to the development of gastric cancer, and understanding mechanisms of vaccine-induced protection.
