| Popis: | We studied the effect of tilorone on the dynamics of IFNα, IFNγ, and IL-1β levels in the lung tissue and blood serum in relation to viral load in the lungs of BALB/c mice with pneumonia caused by influenza virus A/Aichi/2/68 (H3N2). Tilorone was administered per os in doses of 40, 150, and 540 μg per mouse 6, 30, and 78 h postinfection, which simulated the drug regimen used in the clinic for the treatment of influenza and acute respiratory viral infections in Russia and post-Soviet countries. Tilorone reduced viral load with the maximum amplitude (2-3 lg) after 1-2 administrations. The results of studying the dynamics of the cytokine levels in the infected animals in general support the previous hypothesis that, in repeated dosing, tilorone enhances the IFN response (compensates for its deficiency) at the early stages of acute respiratory viral infections and suppresses (damps) excessive production of IFN and proinflammatory cytokines at the later stages. |
