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.
血浆γ-球蛋白组分蛋白、铜和锌阳离子以及它们与人类血清γ-球蛋白形成的金属络合物可诱导人类血细胞产生早期（24小时孵育）白细胞介素-1β。经锌阳离子修饰的蛋白诱导早期白细胞介素-1β的活性比对照γ-球蛋白高1.2倍（p<0.01），而与铜形成的γ-球蛋白金属络合物的活性比对照蛋白低1.4倍（p<0.1）。在48小时孵育过程中，诱导规律发生了变化：γ-球蛋白组分蛋白螯合的锌阳离子减少，而铜阳离子则刺激了金属络合物中蛋白诱导潜力的实现。
