WebThe in vitro effect of macrocyclic trichothecenes, roridin A and verrucarin A, and a non-macrocyclic trichothecene, T-2 toxin, on the concanavalin A-induced murine T-cell blastogenesis was investigated. The macrocyclic trichothecenes inhibited the blastogenesis of both thymocytes and splenocytes, splenocytes being more resistant than thymocytes. WebTesting for T-2 and HT-2 is important because trichothecene mycotoxins are incredibly resistant to heat and UV light. The toxin becomes inactive only after it is heated to 500 degrees Fahrenheit for 30 minutes, so the toxin will survive most food processing. Human consumption can lead to severe health consequences.
