Helicobacter pylori infection causes chronic active gastritis and peptic ulcer disease. In the western world, 10% of people (22.000.000 individuals) develop peptic ulcers. Furthermore, H. pylori infection is tightly correlated with development of gastric cancer with >500.000 mortalities/Y and, H. pylori has been defined a carcinogen by the WHO. The project studies protein-carbohydrate interactions that mediate adherence of H. pylori to stomach tissue. We focus on the Blood Group Antigen Binding Adhesin, BabA, which is the key player attachment protein that targets H. pylori binding to the stomach lining.
