We examined the blastogenic response to phytohaemaglutinin (PHA) in HLA-B8, DR3 positive and negative subjects in the presence or absence of the immunosuppressive Fusarium mycotoxin. HLA-B8, DR3 haplotype was associated with a depression of the response to mitogen in the absence of the mycotoxin, whereas in the presence of deoxynivalenol we could not detect significant differences among individuals either possessing or lacking this haplotype.

The mycotoxins β-zearalenol (β-ZOL) and deoxynivalenol (DON) produce toxic effects that result in diseases in humans and animals. The molecular mechanisms that control the mycotoxin-mediated effects are far from being completely understood. Various results show that these mycotoxins could inhibit cell proliferation. In the present short communication, the influence of β-ZOL and DON on the abundance and phosphorylation state of kinases that are included in regulation of the initiation of mRNA translation (which is correlated with cell proliferation) was compared in porcine endometrial cells (PEC). Our results indicate that these mycotoxins modulate the expression and phosphorylation of these factors in a different manner. Whereas β-ZOL mainly had an impact on the biological activity of the extracellular signal-regulated protein kinases 1 and 2 (ERK1/2), protein kinase B (Akt), eukaryotic initiation factor 4E (eIF4E) and its repressor 4E binding protein 1 (4E-BP1), DON reduced the abundance of p38 MAPk, Akt and specific 4E-BP1 bands. In summary, these results indicate that β-ZOL influences molecular events that are included in the initiation of mRNA translation in the porcine endometrium but DON does not alter such processes clearly.

four groups based on their characteristic functional groups ( Biro, 2003 ). Deoxynivalenol (DON) is a mycotoxin classified as a type B trichothecene. Recent surveys have indicated that more than 50% of different cereal samples were positive for DON
