Scientific summary

ROS production by NADPH oxidases are important for several biological functions such as signaling and innate immunity. However inappropriate or excessive ROS production by NOX enzymes can disrupt cellular redox equilibrium and damage surrounding tissues, thereby contributing to a wide variety of diseases such as rheumatoid arthritis (RA), inflammatory bowel disease (IBD) and cancer. My research is oriented towards the molecular and cellular mechanisms of inflammation, focusing on the regulation of reactive oxygen species (ROS) production by the NADPH oxidases (NOXs) in phagocytes and other cells such as epithelial cells.

My projects are conducted following three axis: 1) the regulation of NOXs enzymes by pro- and anti-inflammatory agents 2) their role in inflammatory processes by investigating their expression and activation status in human inflammatory diseases and in animal models of inflammation. 3) The identification of new regulators and effectors of NOXs during the inflammatory processes.

Our work have highlighted the key role of phosphorylation/dephosphorylation events in the priming, activation and inactivation of NOX2 in response to inflammatory mediators in phagocytes but also in the activation of NOX1 in epithelial cells. Interestingly in human inflammatory disorders such as rheumatoid arthritis, we have demonstrated a dysregulation of NOX2 which was characterized by its hyperphosphorylation and hyperactivation and developed a pharmacological peptide able to prevent NOX2 hyperactivation without affecting its bactericide functions. On the other hand, we have shown that NOX1 was a key player in mucosal immunity and inflammation by controlling the expression of the innate immune protein, lipocalin-2 (LCN-2).  

Our ultimate goal is to identify novel pharmacological targets for the development of therapeutic tools that will limit the deleterious effects of NOXs in inflammatory disorders.
