20120164171Antiviral Activity of Bovine Type III Interferon Against Foot-and-Mouth Disease Virus - Interferons are the first line of defense against viral infections and administration of interferons as biotherapeutics has been demonstrated to be effective in controlling several viral infections. Here we report for the first time the identification and characterization of a member of the bovine type III IFN family, boIFN-λ3. We have expressed boIFN-λ3 using a recombinant replication defective human adenovirus type 5 (Ad5) and demonstrated antiviral activity against foot-and-mouth disease virus (FMDV) and vesicular stomatitis virus (VSV) in bovine cells in vitro. Furthermore, we have tested the efficacy of boIFN-λ3 against FMDV in vivo by inoculation of cattle with Ad5-boIFN-λ3 followed by intradermolingual or aerosol virus challenge. Our results demonstrate that the type III IFN family is conserved in bovines and that treatment of cattle with boIFN-λ3 alone or in combination with IFN-α is able to confer delayed and reduced severity of FMD. Furthermore inoculation with Ad5-boIFN-λ3 alone conferred full protection against aerosol challenge for at least 7 days after administration suggesting that type III IFN used in combination with FMD vaccines could fill one of the current gaps in emergency vaccination against FMDV.06-28-2012

20090181051N-linked glycosylation alteration in E1 glycoprotein of classical swine fever virus and novel classical swine fever virus vaccine - E1, along with Erns and E2 is one of the three envelope glycoproteins of Classical Swine Fever Virus (CSFV). Our previous studies indicated that glycosylation status of either E2 or Erns strongly influence viral virulence in swine. Here, we have investigated the role of E1 glycosylation of highly virulent CSFV strain Brescia during infection in the natural host. The three putative glycosylation sites in E1 were modified by site directed mutagenesis of a CSFV Brescia infectious clone (BICv). A panel of virus mutants was obtained and used to investigate whether the removal of putative glycosylation sites in the E1 glycoprotein would affect viral virulence/pathogenesis in swine. We observed that rescue of viable virus was completely impaired by removal of all three putative glycosylation sites in E1. Single mutations of each of the E1 glycosylation sites showed that CSFV amino acid N594 (E1.N3 virus), as well the combined mutation of N500 and N513 (E1.N1N2 virus) resulted in BICv attenuation. Infection of either E1.N1N2 or E1.N3 viruses were able to efficiently protected swine from challenge with virulent BICv at 3 and 28 days post-infection.
