Figure 3

IL-6 production in LPS-stimulated monocyte-derived macrophages (MDM). IL-6 production in MDM challenged with probiotic CFS (a) and LPS (1 μg/mL) for 4 h and then with CFS (10%) (b) or pretreated with CFS and then stimulated with LPS (c) as indicated in the figure has been tested by ELISA. Results are expressed as mean ± SD of six determinations obtained by six independent subjects. LA: L. acidophilus; LC: L. casei; LL: L. lactis; LR: L. reuteri; SB: S. boulardii. P<0.05 and P<0.01 (CFS-treated MDM versus untreated cells or CFS-treated MDM versus LPS treated cells).
