NFKB1 and asthma: For instance, quercetin could improve asthma response by inhibiting airway inflammation [36, 37]; kaempferol could effectively inhibit inflammation by interfering with MAPK, PI3K, and other signaling pathways to reduce the secretion of related inflammatory factors or could inhibit eosinophil infiltration of airway epithelial cells and airway inflammation by interfering with NF-κB signaling [38, 39]; β-sitosterol might suppress asthma by inhibiting cellular response and subsequent Th2 cytokine release [40].
