英文摘要
Helicobacter pylori CagA-positive strains play a key role in thedevelopment of gastric carcinoma. This project elucidated 1) the mechanism by which H. pylori delivers its oncoprotein CagA into host gastric epithelial cells: 2) identified Pragmin,a human protein the function of which is mimicked by delivered CagA: and 3) uncoveredmolecular pathway that directs reprograming of gastric epithelial cells into intestinal-likecells upon chronic infection with cagA-positive H. pylori. Finally, the H. pylori CagAprotein was crystalized and its three-dimensional structure was solved by X-ray analysis.
