Outline of Final Research Achievements |
Subtilase cytotoxin (SubAB), a toxin produced by Enterohemorrhagic Escherichia coli, induces cytotoxicity through Endoplasmic reticulum (ER) stress. Here we investigated the molecular mechanisms of inhibitory effects of SubAB on host innate immunity. We found that SubAB inhibited IL-1β production and inflammasome activation in macrophages. As a result of mouse infection model, SubAB increased the number of pathogenic bacteria in mouse feces. These data suggested that SubAB enhance EHEC colonization through inhibition of host innate immunity.
