ABSTRACT
Reactive oxygen species (ROS) function in a range of physiological processes such as growth, metabolism and signalling, and also have a pathological role. Recent research highlighted the requirement for ROS generated by Dual oxidase (DUOX) in host-defence responses in innate immunity and inflammatory disorders such as inflammatory bowel disease (IBD), but in vivo evidence to support this has, to date, been lacking. In order to investigate the involvement of Duox in gut immunity, we characterized the zebrafish ortholog of the human DUOX genes. Zebrafish duox is highly expressed in intestinal epithelial cells. Knockdown of Duox impaired larval capacity to control enteric Salmonella infection.
