Identification of Pathogenicity Island Genes Associated with Loss of Type IV Secretion Function during Murine Infection with Helicobacter pylori

20 Mar 2020

Abstract excerpt

Chronic Helicobacter pylori colonization in animal models often leads to downregulation of the type IV secretion system (T4SS), typically by recombination in cagY , which is an essential T4SS gene. However, 17 other cag pathogenicity island ( cag PAI) genes, as well as some non- cag PAI genes, are also essential for T4SS function. To get a more complete picture of how H. pylori regulates the T4SS during animal...
