Bifidobacterium infantis 35624 was also dose-dependently able to suppress the IL-12p70 secretion from all three cocktails, although the inhibition was less potent compared with E. coli Nissle 1917. Saccharomyces boulardii and VSL#3 were not able to suppress IL-12p70 secretion, and rather seemed to further support the cocktail-induced IL-12p70 secretion, in particular in combination with cocktail XL184 ic50 3. IL-10 is a potent anti-inflammatory cytokine, which may be involved in mediating the suppressive activity seen for E. coli Nissle 1917 and B. infantis 35624 in the suppression of cocktail-induced IL-12p70 secretion. We wished to test whether IL-10 secretion was important for the suppressive activity of these two strains using IL-10-neutralizing antibody. First, we tested whether IL-10 by itself is able to suppress cocktail-induced IL-12p70 secretion, by adding recombinant IL-10, 4?h before the addition of cocktail 1 (Fig. 5a). Indeed, 20??ng?mL?1 of IL-10 could suppress cocktail-induced IL-12p70 secretion, JQ1 and this suppression was prevented by the addition of the IL-10-neutralizing antibody MAB217 in a dose-dependent manner (Fig. 5a). In order to test whether the secretion of IL-10 induced by E. coli Nissle 1917 and B. infantis 35624 could be responsible for the IL-12p70-suppressive activity, we added 200?��g?mL?1 bacteria together with increasing concentration of the neutralizing antibody, 4?h before the addition of cocktail (Fig. 5b). In this case, the antibody was not able to prevent the IL-12p70-suppressive activity of the two probiotics, showing that IL-10 secretion is not directly involved in the inhibitory activity of E. coli Nissle 1917 and B. infantis 35624. Saccharomyces boulardii induced very low levels of IL-10 and IL-12p70 (Figs 1 and 2) and did not suppress any of the three IL-12p70-inducing cocktails, which led us to speculate whether the clinical effects of S. boulardii are not associated with DC interaction and possibly independent of effects on immune cells. We speculated whether S. boulardii was able to stimulate other proinflammatory cytokines and chemokines when added to human DCs. A dose�Cresponse study was conducted at doses of Panobinostat research buy 1�C50�C200?��g?mL?1, and the levels of TNF��, IL-6, IL-23, IL-12p40 and CXCL1 were measured in the culture supernatant (Fig. 6a�Ce). The Th17-inducing DC cytokine IL-23, identified in inflammatory tissue from CD patients (Fuss et al., 2006; Kobayashi et al., 2008), was significantly higher in DCs from E. coli Nissle 1917, L. acidophilus NCFM? and B. infantis 35624-treated DCs than S. boulardii-treated DCs (P
