Abstract excerpt
CagA protein of Helicobacter pylori is injected into the epithelium, where CagA undergoes tyrosine phosphorylation and activates proliferation signals. However, the importance of these CagA activities for pathogenesis has yet to be resolved. The aim of this study is to analyze the genetic and functional variability of cagA gene of clinical strains in relation to gastric diseases. Thirty-six H. pylori strains were...
