. H. pylori outer membrane vesicles budding. The release of outer membrane vesicles by H. pylori is an alternative mechanism for the delivery of bacterial toxins and antigens to the gastric mucosa. These small vesicles are 50 to 300 nm in diameter. They contain VacA and other proteins such as porins within the trilayered membrane (OM, outer membrane; PS, periplasm; IM, inner membrane; C, cytoplasm).
