Tumor necrosis factor-α regulates interleukin-33 expression through extracellular signal-regulated kinase, p38, and nuclear factor-κB pathways in airway epithelial cells
文摘
Interleukin (IL)-33 plays an important role in controlling immune responses in barrier tissues, and is a potent mediator of inflammatory diseases such as asthma, rheumatoid disease, and chronic rhinosinusitis. The aims of the present study were 2-fold: (1) to determine the stimulatory effect of tumor necrosis factor-α (TNF-α) on IL-33 production in nasal epithelial and A549 cells; and (2) to identify downstream pathways that activate IL-33 production.
