Gene expression of the transcription factors T-bet, GATA3, RORC, and FOXP3 were evaluated in a set of 14 CRSwNP and 8 CRSsNP samples [52], which revealed that eosinophilic CRSwNP was characterized by a higher level of GATA3 gene expression compared to non-eosinophilic CRSwNP. This evidence concerns the gene FOXP3 and chronic rhinosinusitis with nasal polyps.
