Abstract

AbstractHelicobacter pylori (H. pylori) causes the most prevalent bacterial infection worldwide, and more than half of the world's population is infected with H. pylori. Classified as a group 1 carcinogen of gastric cancer, H. pylori infection causes the most common chronic gastritis, which is able to progress to chronic atrophic gastritis, dysplasia, and even gastric cancer. The inflammasomes are important cytosolic multiprotein complexes to coordinate the host defense against foreign microorganisms and control the inflammatory response. It is also well‐known that inflammasome plays an important role in the occurrence of H. pylori‐induced gastric inflammation. During infection and inflammation, the activation process of inflammasome is tightly regulated by host immune system. However, excessive activation of inflammasome is closely related to the production of excessive cytokines that cause the body injury and resulting in various inflammatory diseases. In this review, we elaborate the activation and assembly mechanisms of inflammasome, the structure of different inflammasome complexes, host factors in vivo and drugs in vitro that regulate inflammasome signaling during H. pylori infection, aiming to provide novel insights and strategies for identifying new therapeutic targets for the treatment of H. pylori‐associated gastric mucosal diseases.
