(B) GFP+ cells were sorted. The transcript level of Fak was measured by RT-qPCR (left) and the protein level of FAK was measured by immunoblot analysis (right). (C) The expression of GFP, IFN-γ, IL-4, IL-17A, and FOXP3 was analyzed by flow cytometry (top). The statistical analysis was performed on pooled data from five independent experiments (bottom). Error bars represent the standard deviation. The significance of differences between groups was determined by one-way ANOVA (A) and Student t test (B, C) . ***P < 0.001; ****P < 0.0001, n.s., not significant.
