The effects of TL1A on the differentiation of naïve CD4+ T cells into Th9 cells and the expression of IL-9. (a) Immunofluorescence staining of Th9/IL-9 in colon tissue (magnification 40×). (b) Proportion of Th9 cells by flow cytometry. (c) Immunofluorescence staining of Caco-2 cells (magnification 400×). (d) The expression of IL-9 in culture medium. *P<0.05 indicates the comparison with the Caco-2 group at the same time point. #P<0.05 indicates the comparison between Caco-2+TGF-β+IL-4+TL1A and Caco-2+TGF-β+IL-4 groups at the same time point.
