Flavonoid Quercetin Enhances Nuclear Factor Erythroid 2-Related Factor 2 Pathway Activation and Reduces Inflammatory Cytokines in Asthmatic Airway Epithelial Cells

This study suggests that quercetin may be a promising therapeutic agent to improve health outcomes in asthma by activating the Nrf2 pathway to reduce oxidative stress and pro-inflammatory cytokines in airway epithelium, which warrants further mechanistic and clinical investigation.
