Interleukin (IL)-17A is a highly inflammatory cytokine and is known to be produced by Th17 cells. The importance of IL-17A expression in nasal epithelial cells is not well understood. The goal of this study is to explore the expression of IL-17A in nasal epithelial cells in vivo and in vitro. IL-17A and staphylococcal enterotoxin B (SEB) were detected by(More)
OBJECTIVE Staphylococcus aureus enterotoxin B (SEB) might participate in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). However, the exact mechanism of polyp formation in CRSwNP remains unclear.
