  • Title: Comparison of antiviral activity of recombinant and natural interferons against crimean-congo hemorrhagic Fever virus.
    Author: Karlberg H, Lindegren G, Mirazimi A.
    Journal: Open Virol J; 2010 Apr 22; 4():38-41. PubMed ID: 20517491.
    Abstract:
    As a first line of defence against a virus infection, mammalian cells elicit an innate immune response, characterized by secretion of type I interferons (IFN) and up-regulation of interferon stimulated genes (ISGs). We have previously included Crimean Congo Hemorrhagic Fever Virus (CCHFV) in the list of type I IFN-sensitive viruses. In this in vitro study, we have compared the antiviral activity of two recombinant IFN-alpha preparations (Roferon A and Intron A) with a natural IFN-alpha produced in human leukocytes (Multiferon). Our results clearly demonstrate that these commercially available IFNs have significant antiviral activities against CCHFV. However, we could show that Multiferon inhibits viral replication more efficiently than the two recombinant IFN alpha preparations.
