Most studies on the immunomodulating effects of interferon-gamma (IFN-gamma) have been performed in vitro, using recombinant mouse and human IFN-gamma preparations. Recently, recombinant rat IFN-gamma (rRIFN-gamma) became available, enabling extensive studies with this new preparation in vivo. In the present study a LEW rat model was used to determine the efficacy of rRIFN-gamma on immune functions in vivo. LEW rats were treated with rRIFN-gamma by continuous intravenous infusion at a dosage of 1.5 x 10(5) U/kg.h for 2 consecutive days. Twelve hours after cessation of rRIFN-gamma administration immune functions, including NK-cell activity, phagocytosis, and mitogen-induced blastogenesis, were assessed. All experimental animals displayed a marked reduction in the number of peripheral blood and bone marrow cells when compared with controls (p less than 0.005). Assessment of immune functions revealed a significant enhancement of NK-cell activity (p less than 0.001), phagocytosis (p less than 0.05), and mitogen-induced blastogenesis (p less than 0.05). These findings indicate that rRIFN-gamma, when given in high dosages, has a stimulatory effect on various immune functions, which substantiates its important immunological role in vivo.
