The results of cell counts, cytokine expressions and RT-PCR used for Th1, Th2, Th17, Treg. (A-D) The results of cell counts: The DNMT inhibitor 5-Aza decreased cell counts of Th2, Th17 cells and increased cell counts of Treg cells; (E-H) The results of cytokine expressions: The DNMT inhibitor 5-Aza decreased cytokine expressions of Th2, Th17 cells and increased cytokine expressions of Treg cells; (I-L) The results of RT-PCR: The DNMT inhibitor 5-Aza inhibits transcription levels.The ※ in the figure indicates that there were statistical differences compared with the blank control group.
