title: New approaches for Helicobacter vaccine development--difficulties and progress.
abstract: Despite the enormous progress in understanding the process of bacterial pathogenesis and interactions of pathogens with eucaryotic cells the infectious diseases still remain the main cause of human premature deaths. It is now recognized that Helicobacter pylori infects about half of the world's population. Based on results of clinical studies the World Health Organization has assigned H. pylori as a class I carcinogen. The review presents new achievements aimed at construction efficient and safe anti-Helicobacter vaccine. We discuss the new global technologies such as immunoproteomics employed for selecting new candidates for vaccine construction as well as new vaccine delivery systems. The review presents also our knowledge concerning H. pylori interaction with immune system which might facilitate modulation of the host immune system by specific adjuvant included into vaccine.
