Figure Lengend Snippet: ( A ) Western blot analysis of phosphorylated Smad1/5/9 and total Smad1 in Th17 cells. ( C , D ) qRT-PCR quantification of Il17a and Rorc mRNA. ( E , F ) Flow cytometry analysis was conducted to assess the expression of IL-17a in CD4 + T cells. ( G ) ELISA measurement of IL-17 A in culture supernatants. (H) Western blot detection of phosphorylated Stat3 and total Stat3 in Th17 cells. ( I ) Cross-linking of Smad1 and Stat3 in Th17 was detected by co-immunoprecipitation experiment (IgG immunoprecipitation as negative control). ( J ) Nuclear Stat3 protein levels were assessed by Western blotting. Quantitative analysis of Stat3/H3 ratio. Data are normalized to the group without BMP6 and LDN193189 (set as 1.0). Statistical significance was determined by one-way ANOVA followed by a Bonferroni post hoc test. Data are reported as means ± SD ( n = 3). * P ≤ 0.05; ** P ≤ 0.01; *** P ≤ 0.001, ns = not significant. IL-17, interleukin-17; BMP, bone morphogenetic protein.
