Figure 5. Addition and synergy of combined IL-17 and TNF-α to induce the production of IL-6 and IL-8 on FLS.
A. After cells were stimulated with IL-17 and TNF-α for 12 h, mRNA expressions of cytokines (IL-6, IL-8) were determined by realtime-PCR. B. Secretions of cytokines (IL-6 and IL-8) in culture media were measured by ELISA. All results are representative of at least three independent experiments.
