Figure 4. Effect of inulin and FOS on inflammatory response of macrophages against P. aeruginosa (WT).

Macrophages were incubated with WT P. aeruginosa cells (ratio 1/5) for 4 hours in either the absence or the presence of 5 mg/ml FOS and inulin prior to the determination of IL-6 (A), IL-10 (B) and TNF-α secretion (C). Values are means ± s.e.m., n = 6–8; ^*P<0.05 vs macrophage without bacteria and ^&P<0.05 vs WT in the absence of inulin or FOS (ANOVA followed by least significance tests).
