Immunosuppressive effects of four trichothecene mycotoxins

The trichothecenes are a family of mycotoxins contaminating some food and feeds. We have studied the inhibitory effect of four of them including less toxic compounds: T-2 toxin, DAS, DON and Trichodermin, on normal human peripheral blood lymphocytes and murine splenic lymphocytes. The results show that even for the least toxic compound, inhibiting concentrations can be realised in the blood by common alimentary contamination. © 1990 Taylor & Francis Ltd.
