ABSTRACT
T-2 toxin is recognized as the most potent and prevalent secondary metabolite among monotrichous mycotoxins produced by Fusarium species. Multiple studies have substantiated the hepatotoxic effects of T-2 toxin. This study aimed to investigate whether NF-κB and NLRP3-mediated pyroptosis is involved in the underlying mechanism of T-2 toxin hepatotoxicity. We designed three groups of rat models, blank control; solvent control and T-2 toxin (0.2 mg/kg body weight/day), which were euthanized at week 8 after gavage staining of the toxin. Through HE staining and biochemical indicators associated with liver injury, we observed that T-2 toxin induced liver damage in rats. By Western blot analysis and qRT-PCR, we found that the expression levels of pyroptosis-related genes and proteins were significantly higher in the T-2 toxin group. In addition, we also found a significant increase in the expression of p-NF-κB protein, an upstream regulator of NLRP3. In conclusion, NF-κB and NLRP3-mediated pyroptosis may be involved in the mechanism of hepatotoxic action of T-2 toxin, which provides a new perspective.
