Mitogenic effects of mycotoxins on T4 lymphocytes.
Mycotoxins have compromising effects on varied biological systems, even when ingested at levels which do not evoke manifestations of clinical mycotoxicoses. No data have been previously found as to the therapeutic and mitogenic effects of mycotoxins. This was the objective of the present work. Human peripheral T4 lymphocytes were obtained by venipuncture, propagated in RPMI 1640 medium and challenged with varied concentrations of aflatoxins, B1, B2, G1, and G2. The cells were stained with propidium iodide and fluorescent isothiocyanate (FITC) and examined microfluorometrically. All the mycotoxins were significantly mitogenic on the basis of dose response. No adverse effects were observed when doses of 10, 50 and 100 micrograms were administered on a modest clinical basis to volunteers.[1]References
