Luteolin reduces the secretion of IL-36γ and IL-1β in Beas-2B cells and inhibits the activation of mitogen-activated protein kinase (MAPK) pathways under lipopolysaccharide (LPS) stimulation. (A–D) IL-1β, p-p38, p38, p-REK, ERK, p-JNK and JNK in Beas-2B cells under LPS stimulation as detected by western blot. (E) IL-36γ in Beas-2B cells under LPS stimulation as detected by enzyme-linked immunosorbent assay (ELISA). (F–I) Protein intensity analysis of IL-1β, p-p38, p38, p-REK, ERK, p-JNK and JNK in Beas-2B cells under LPS stimulation as detected by western blotting. *p< 0.05 versus the control group. #p< 0.05 versus the LPS group.
