Indeed, the effect of IL-4/IL-13 and IL-5 on nasal epithelial repair was already showed [29] but to date, no study has precisely described the role of IL-6, IL-9 and IL-10 (new ILs described in nasal polyposis) on human nasal epithelial cells in an in vitro wound repair model. The gene discussed is IL9; the disease is Nasal polyposis.
