Helicobacter pylori(Hp)is a Gram-negative bacterium that colonizes in the gastric mucosa.Hp induces the production of cancer-associated fibroblasts(CAF)in the stomach.The virulence factors of Hp and CAF trigger epithelial-mesenchymal transition(EMT),leading to local inflammation,damage to the gastric mucosa,and the occurrence of chronic gastritis.Here,we summarize the molecular mechanisms of CAF mediated gastric EMT after Hp infection,providing new insights into potential molecular targets and strategies for the future treatment of Hp infection associated gastric cancer.
