Figure 4. Effect of IL-17 (10 ng/mL for 48 hrs) on induction of (A) IL-6 and IL-8 synthesis and release by gingival fibroblasts, and (B) IL-1ß and TNF- synthesis and release by adherent human monocyte/ macrophages in vitro. The results are from triplicate measurements, n = 5, for both non-stimulated (black bars) and stimulated cultures (white bars). Means ± SEM are shown. *p < 0.05; analysis by t tests.
