Research Interests

Molecular and cellular basis of pathogenicity of Helicobacter pylori infection and the relationship to gastric malignancy. We are studying the interaction between Helicobacter pylori, the causative agent of peptic ulcers and gastric cancer, and gastric epithelial cells. Genes encoded by a pathogenicity island in H. pylori comprise a secretory apparatus that secretes bacterial CagA protein into target gastric epithelial cells. CagA is phosphorylated on tyrosine residues by host cell kinases and is associated with signal transduction and changes in the cytoskeleton and motility. Cells that have received CagA develop an elongated phenotype and become motile. Further studies suggest that the full-length protein localizes to junctional adhesion sites and acts as an oncoprotein to stimulate the cMET receptor, leading to changes in cell polarity, motility and differentiation, changes which may be related to the development of gastric cancer. We have used an animal model of infection to study gastric lymphoma (MALT lymphoma), including the cellular response. In addition, chronically infected animals are used to address the specific cellular interactions between adipose cells and gastric epithelial cells that are necessary to provide protective immunity following immunization.
