Production of Late IFN-α Induced by Plasma γ-Globulin Fraction Proteins and Their Metal Complexes

Abstract

Plasma γ-globulin fraction proteins, copper and zinc cations, and metal complexes they form with human serum γ-globulin induce the production of IFN-α by human blood cells throughout the periods of up to 72 h. Zinc cation-modified protein by 1.6 times (p<0.05) more actively induces late IFN-α than the control γ-globulin; γ-globulin-copper metal complex is 2-fold (p<0.002) more effective than the control protein. The results indicate that functional relationships between the components inducing the production of late IFN-α differ from the effects realized during the early period of induction.
