In line, the T2-associated chemokine CCL17 showed higher levels in nasal secretions of AERD patients (p = 0.0025), while the IL-1 receptor antagonist (IL-1RA) was significantly elevated in nasal secretions of CRSwNP patients (p = 0.0148). This evidence concerns the gene CCL17 and chronic rhinosinusitis with nasal polyps.
