Fig 1 Expression of FOXP3+ cells in nasal mucosa from healthy individuals (controls, CON) and subjects with CRSsNP or CRSwNP. Lack of staining is observed by blocking with FOXP3-immunizing peptide. Human tonsil sections served as a positive control with FOXP3+ cells located in the parafollicular cortex (T-cell zone). Original magnification was ×200 or ×400. For human tonsil magnification was ×100 or ×400. Representative slides are shown (n = 6 per group).

Fig 2 mRNA expression of transcription factors (FOXP3, T-bet, GATA-3) involved in naive T-cell differentiation in controls (CON), CRSwNP, and CRSsNP expressed as logarithm of normalized relative expression units/30 ng cDNA.

Fig 3 mRNA expression of key cytokines IFN-γ (TH1), IL-4, IL-5, IL-13 (TH2) (A), and iTreg-related TGF-β1 and IL-10 in controls (CON), CRSsNP, and CRSwNP (B), expressed as logarithm of normalized relative expression units/30 ng cDNA. For TGF-β1 and IFN-γ, additional protein measurements were performed, expressed as picograms per milliliter.
