IL25 and Nasal polyposis: Following A. fumigatus and D. pteronyssinus stimulation, no change in cytokines release was observed in epithelial cells derived by nasal polyps of patients with CRSwNP (A. fumigatus stimulation: IL-25 from 0.12 ± 0.06 pg/ml to 0.24 ± 0.09 pg/ml; IL-33 from 2.25 ± 1.2 pg/ml to 1.34 ± 0.7 pg/ml; TSLP from 0.77 ± 0.5 pg/ml to 0.43 ± 0.1 pg/ml; D. pteronyssinus stimulation: IL-25 from 0.12 ± 0.06 pg/ml to 0.15 ± 0.06 pg/ml; IL-33 from 2.25 ± 1.2 pg/ml to 4.31 ± 3.4 pg/ml; TSLP from 0.77 ± 0.5 pg/ml to 0.56 ± 0.2 pg/ml; see Figures 1, 2, and 3).
