The researchers previously developed a strain of H pylori that is missing a gene essential for chemotaxis—the ability to sense and move in response to chemicals in the environment—and causes much less inflammation than normal strains. In this study, they found that immune responses to infections with the mutant strain lacked T-helper cell type 17 immune cells, which promote chronic inflammation in response to a combination of bacterial infection and dying host cells.
