Levels of INF-γ, IL-4, IL-17, and Foxp3 protein in UCC, CIN, and controls. The levels of INF-γ protein in UCC (A) and CIN (B) groups were lower than in the control group (C). Furthermore, the level of INF-γ protein in UCC was even lower than in the CIN group (P<0.05). The levels of IL-4 protein in UCC (D) and CIN (E) groups were higher than in the control group (F). The levels of IL-17 protein in UCC (G) and CIN (H) groups were higher than in the control group (I). The levels of Foxp3 protein in UCC (J) and CIN (K) groups were higher than in the control group (L). The conditions of IL-4, IL-17 Foxp3 and proteins were similar. They were all higher in UCC and CIN groups than in the control group.
