RESUMEN
Induction of porcine interferon (PoIFN) with different lectins (phytohaemagglutinin, Lens culinaris lectin, Arachis hypogea lectin) in various concentrations (500, 50 and 5 micrograms/ml) was studied. Kinetics of PoIFN appearance was analyzed by antiviral and antiproliferative tests in human transformed and nontransformed cells. The relation between antiviral and antiproliferative activity of PoIFN in terms of respective units was determined. PoIFN was characterized in comparison with human interferon alpha by the acidostability and thermostability tests.

To investigate the possible interactions between human and porcine interferons (IFNs) in vitro, human transformed (FL) and nontransformed (HEF) cells were treated with either HuIFN alpha and/or gamma and porcine alpha and/or gamma. In both cases the antiproliferative activity was measured to determine the effects of different combinations between human and porcine IFNs on cell proliferation. Combinations of human and porcine IFNs acted mostly antagonistically with exception of IFN combination Hu-alpha/Po-gamma which showed a synergic cooperativity in therms of antiproliferative activity on human transformed cells.
