[The immunoregulatory properties of reaferon].

The influence of human recombinant alpha-interferon (reaferon) on cell-mediated and humoral immune response has been studied. Experimental facts on the blast transformation of lymphocytes, humoral immune response and the reaction of delayed hypersensitivity are presented. The study has shown that reaferon possesses the main immunoregulatory properties, characteristic of natural human leukocytic alpha-interferon. Manifestation of these properties depends on the dose of preparation and the time of its use.
