However, the CCR6-IL-17- Treg cells subsets increased in patients with allergic asthma (Figure 3D).The percentage of Foxp3+IL-17A+ Treg cells was significantly lower in patients with aAS than in HC subjects (1.79% vs. 9.06%, median, respectively; P < 0.05, Figure 3B). The gene discussed is FOXP3; the disease is allergic asthma.
