AbstractFusarium toxins have been arousing public interest in recent years because of their potential health hazards for humans and agricultural livestock. It was hypothesized that selected pro-inflammatory cytokines might serve as sensitive biomarkers of the predicted adverse effects of Fusarium toxins on the basis of their potential ability to induce immune and intestinal alterations comparable to those in human chronic inflammatory infection. Consequently, the aim of this study was to elucidate individual and combined effects of four common Fusarium toxins, deoxynivalenol (DON), nivalenol (NIV), zearalenone (ZEA) and fumonisin B1 (FB1) on the mRNA expression of pro-inflammatory cytokines (IL1alpha, IL1beta, IL6, IL8, TNFalpha and MCP-1) using a porcine jejunal epithelial cell line, IPEC-J2. Based on a dose-response relationship between individual mycotoxins and cell viability (MTT assay) that was previously established, cytotoxic and non-cytotoxic concentrations were selected to investigate combinations of two, three and all four of the mycotoxins. In general, up-regulation of pro-inflammatory cytokine mRNA expression occurred for both individual and mixtures of Fusarium toxins at cytotoxic concentrations, whereas significant up-regulation of pro-inflammatory cytokine mRNA mostly obtained when the toxins existed in mixtures at non-cytotoxic concentrations and these mixtures were found to cause cytotoxicity from MTT assay determined previously. Therefore, it may be concluded that some of the changes in the mRNA expression of IL1alpha, IL1beta, IL6, IL8, TNFalpha and MCP-1 could be cytotoxicity-related. It was also noted that additive effects were not always observed for the mixtures. These data suggest that individual or mixtures of Fusarium toxins could cause or exacerbate intestinal inflammation. These also provide a better understanding of the possible effects of Fusarium toxins, alone or in combinations on the immunological defense mechanisms of IECs, which would contribute to the risk assessment of these toxins.
