Regulated cytokines level and characteristic transcriptional factor expression of CD4⁺T cells in TOFA-treated asthma mice. a Cytokines IFN-γ, IL-4, IL-17A and IL-10 in BALF and in serum were examined by ELISA. b The transcription factors T-bet, GATA3, RORγt and Foxp3 were measured in lung tissue by Real-time quantitative PCR. All data are represented as mean ± SEM (n = 5–6 mice per group). *p < 0.05; **p < 0.01; ***p < 0.001; ^NSp > 0.05
