Abstract<\/h3>\r\n
\r\n

SIGNIFICANCE:<\/h4>\r\n

Despite their intrinsic cytotoxic properties, mounting evidence indicate that ROS physiologically produced by the NADPH oxidases of epithelial cells (NOX1, DUOX2) and phagocytes (NOX2) are critical for innate immune response and homeostasis of the intestinal mucosa. However, dysregulated ROS production could be a driving factor in inflammatory bowel diseases (IBD). Recent advances: In addition to NOX2, recent studies have demonstrated that NOX1- and DUOX2-derived ROS can regulate intestinal innate immune defense and homeostasis by impacting many processes, including bacterial virulence, expression of bacteriostatic proteins, epithelial renewal and restitution, and microbiota composition. Moreover, the antibacterial role of DUOX2 is a function conserved in evolution as it has been described in invertebrates, and lower and higher vertebrates. In humans, variants of the NOX2, NOX1 and DUOX2 genes, which are associated with impaired ROS production, have been identified in very early-onset IBD, but overexpression of NOX\/DUOX, especially DUOX2, has also been described in IBD, suggesting that loss-of-function or excessive activity of the ROS-generating enzymes could both contribute to disease progression.<\/p>\r\n

CRITICAL ISSUES:<\/h4>\r\n

Therapeutic perspectives aiming at targeting NOX\/DUOX in IBD should take into account the two sides of NOX\/DUOX-derived ROS in intestinal inflammation. Hence, NOX \/DUOX inhibitors or ROS inducers should be considered as a function of the disease context.<\/p>\r\n

FUTURE DIRECTIONS:<\/h4>\r\n

A thorough understanding of the physiological and pathological regulation of NOX\/DUOX in the gastrointestinal tract is an absolute pre-requisite for the development of therapeutic strategies that can modulate ROS levels in space and time.<\/p>\r\n<\/div>","paragraphe_en":"","documents":null},"yoast_head":"\nThe dual role of ROS-generating NADPH oxidases in gastrointestinal inflammation and therapeutic perspectives. -
