Stable adhesion complexes are crucial for maintenance of healthy epithelia and represent the first barrier for microbial pathogens. We have recently identified a novel secreted effector in H. pylori, the protease HtrA, which can cleave the junctional proteins E-cadherin, claudin-8 and occludin. Our findings provide a potential novel mechanism how pathogens can destroy cellular junctions in order to get access to deeper tissues and trigger disease-associated processes. This project is therefore designed to pinpoint these novel HtrA targets and to study downstream signalling events.
