Increased level of interleukin-13, but not interleukin-4 and interferon-γ in chronic rhinosinusitis with nasal polyps

Abstract

IL-13 with high level of total IgE was observed in the patients with CRSwNP, which predisposes them to have concomitant asthma. IFN-γ seems to be down-regulated in the patients with CRSwNP, but could be over-expressed in the presence of aspirin intolerance.
