pubmed:abstractText |
VacA, the vacuolating cytotoxin secreted by Helicobacter pylori, is believed to be a major causative factor in the development of gastroduodenal ulcers. This toxin causes vacuolation of cultured cells and it has recently been found to form anion-selective channels upon insertion into planar bilayers as well as in the plasma membrane of HeLa cells. Here, we identify a series of inhibitors of VacA channels and we compare their effectiveness as channel blockers and as inhibitors of VacA-induced vacuolation, confirming that the two phenomena are linked. This characterization opens the way to studies in other experimental systems and to the search for a specific inhibitor of VacA action.
