Activity of recombinant human alpha interferon against influenza virus infection in mice.
The in vivo antiviral activity of recombinant human leukocyte hybrid interferon, HuIFN-alpha AD, was examined. Results showed that this material in highly purified form did not protect mice against a lethal dose of influenza virus, although administration of natural MuIFN-alpha/beta to mice infected with a lethal dose of influenza virus had a marked protective effect. The effect of alveolar macrophages treated with IFN on influenza virus replication was examined in vitro. The antiviral activity of alveolar macrophages treated with HuIFN-alpha AD was lower than that of MuIFN-alpha/beta. It is concluded that HuIFN-alpha AD is effective in direct inhibition of influenza virus, but not in indirect inhibition mediated by alveolar macrophages or in protection of mice from influenza virus infection.
