We observed significantly elevated levels of the type 2 response-associated cytokines IL-5, IL-9 and Eotaxin-3 in the nasal secretions of patients with NP (N-ERD and CRSwNP) compared to patients without NP (CRSsNP and DC) (please refer to Figures 2A–C for p-values). The gene discussed is IL5; the disease is chronic rhinosinusitis with nasal polyps.
