Moreover, galectin 10 (GAL10) and eosinophil peroxidase (EPO) levels in both the tissues (CRSwNP: nasal polyp/CRSsNP: inferior turbinate) and serum EVs are higher in patients with CRSwNP than in those with CRSsNP [61]. This evidence concerns the gene CLC and chronic rhinosinusitis with nasal polyps.
