Therefore, the aim of the present study was to determine the frequency of infiltrating CD4+ and CD8+ T cells and macrophages (CD68+ cells), additionally the mRNA expression of Th cell subsets (T-bet, GATA3, Ror-γt, and FoxP3) in the sinonasal mucosa of CRSwNP and CRSsNP patients in comparison to healthy controls. This evidence concerns the gene GATA3 and chronic rhinosinusitis with nasal polyps.
