An experimental model of hepatitis C virus (HCV) infection in cell culture in vitro was used to study the influence of interferon (IFN) inducers on HCV infection activity. In combination with the RT-PCR method, this model was also used to study the dynamics of cytokine mRNA activity for IFN-alpha, IFN-gamma, IL-I beta, IL-2, IL-4, IL-6, IL-8, BL-10, IL-12, IL-18, and TNF-alpha. The research was carried out using long-term cell cultures SW-13 (human paradrenal adenocarcinoma cells) and MT-4 (human cells of lymphoblastoid origin) inoculated with HCV under conditions of acute infection. The obtained data showed that cell cultures SW-13 and MT-4 were sensitive to replication of HCV (cytopathogenic variant). The addition of IFN inducers Savratz, Kagocel, and Cycloferon to infected cell cultures usually resulted in suppression of HCV reproduction in these cultures. Cycloferon had the greatest antiviral activity (virus titer level decreased by a factor of 2.51 g and 5.51 g TCD50 in cell cultures SW-13 and MT-4, respectively). It was suggested that induction of IFN-gamma, IL-4 and IL-8 plays a certain role in HCV reproduction suppression. The results of this work provide an opportunity for more efficacious use of IFN inducers in therapy of HCV infection.
