Abstract:
Plasma γ-globulin fraction proteins, copper and zinc cations, and metal complexes formed by them with human serum γ-globulin induce the production of early (24-h incubation) IL-1β by human blood cells. The protein modified by Zn cations 1.2 times more actively (p<0.01) induced early IL-1β than the control γ-globulin, while γ-globulin metal complex with copper was 1.4 times less active (p<0.1) than the control protein. The regularities of induction changed over the course of 48-h incubation: zinc cations chelated by γ-globulin fraction protein reduced, while copper cations stimulated the realization of the protein induction potential in the metal complex.
