An evaluation of the CT scores and mRNA expression of IL-10 and other cytokines, including IL-25, IL-33, IFN-γ, IL-17A, IL-4, and IL-5 (S3 Fig) revealed significant positive correlations between the CT scores and expressions of other cytokines (IL-25, IFN-γ, IL-17A, and IL-5), as well as IL-10, in patients with CRSwNP.” Here, IL4 is linked to chronic rhinosinusitis with nasal polyps.
