FIGURE 3 Yinxieling(YXL) inhibits the ratio and number of Langerhans cell(LC) and its transcription factor PU.1 in epiderm. A: Gating strategy and flow cytometry scatter plot to identify LCs; B: Frequency of MHCII+CD207+ LCs; C: Gating strategy and flow cytometry scatter plot to identify PU.1; D: Frequency of MHCII+CD207+ PU.1+LCs. n = 3, repreated at least twice with similar results. Comparing to IMQ group, *p <0.05, **p <0.01.
