dc.description.abstract | Probiotic and prebiotics, often called “immune-enhancing” feed additives, are believed to deal with pathogens,
preventing the need of an immune response and reducing tissue damage. In this study, we investigated if a
recently developed b-galactomannan (bGM) had a similar protective role compared to Saccharomyces cerevisiae var.
Boulardii (Scb), a proven probiotic, in the context of enterotoxigenic Escherichia coli (ETEC) infection. ETEC causes
inflammation, diarrhea and intestinal damage in piglets, resulting in large economic loses worldwide. We observed
that Scb and bGM products inhibited in vitro adhesion of ETEC on cell surface of porcine intestinal IPI-2I cells. Our
data showed that Scb and bGM decreased the mRNA ETEC-induced gene expression of pro-inflammatory cytokines
TNF-a, IL-6, GM-CSF and chemokines CCL2, CCL20 and CXCL8 on intestinal IPI-2I. Furthermore, we investigated the
putative immunomodulatory role of Scb and bGM on porcine monocyte-derived dendritic cells (DCs) per se and
under infection conditions. We observed a slight up-regulation of mRNA for TNF-a and CCR7 receptor after coincubation of DC with Scb and bGM. However, no differences were found in DC activation upon ETEC infection
and Scb or bGM co-culture. Therefore, our results indicate that, similar to probiotic Scb, prebiotic bGM may protect
intestinal epithelial cells against intestinal pathogens. Finally, although these products may modulate DC activation,
their effect under ETEC challenge conditions remains to be elucidated. | ca |
