The Naturally Attenuated Kunjin Strain of West Nile Virus Shows Enhanced Sensitivity to the Host Type I Interferon Response
17 Mar 2011
Abstract excerpt
The host determinants that contribute to attenuation of the naturally occurring nonpathogenic strain of West Nile virus (WNV), the Kunjin strain (WNV(KUN)), remain unknown. Here, we show that compared to a highly pathogenic North American strain, WNV(KUN) exhibited an enhanced sensitivity to the antiviral effects of type I interferon. Our studies establish that the virulence of WNV(KUN) can be restored in cells...
