Smoking-aggravated oral candidiasis: Nrf2 pathway dampens NLRP3 inflammasome

While cigarette smoke compounds are known to have immunosuppressive effects on the oral mucosa, the relationship between in vivo immune dysfunction caused by smoking and the development of oral Candida infections remains largely unexplored. In a recent issue of The Journal of Cellular and Molecular Medicine, Ye and colleagues provide evidence that smoking increases oral mucosa susceptibility to Candida albicans infection via the activation of the Nrf2 pathway, which in turn negatively regulates the NLRP3 inflammasome. This opens new perspective in considering Nrf2 as a relevant target for smoking-induced C. albicans-related oral diseases.
