Forkhead box P3 (FoxP3)⁺ CD4⁺ T cells express interleukin (IL)-17 in allergic rhinitis/nasal polyposis (AR/NP) nasal mucosa. CD4⁺ T cells were isolated from nasal mucosa collected in this study and analysed by flow cytometry. A1-4: flow cytometry dot plots show FoxP3⁺ cells (gated cells). B1-4: histograms indicate IL-17⁺ cells in gated cell population in A1-4. Summarized data are also presented in Fig. S3. Cells stained with isotype immunoglobulin (Ig)G did not show any positive staining (data not shown). Each group consisted of samples from six patients.
