Figure 4. Plasma levels of IL- 22, IL-17 and IFN-γ decreased following MTX+LEF treatment in RA responders.
The plasma levels of IL-22 (A), IL-17 (B), and IFN-γ (C) were measured by ELISA in RA responders and non-responders before treatment (0 W), after treatment (12 W), and in HC. R, response group; NR, non-response group. *P < 0.05 versus before treatment in response group. #P < 0.05 versus healthy control. △P < 0.05 versus non-response group at the same time point.
