چکیده

West Nile virus causes fatal encephalitis in humans, mice, and other vertebrates. In the present study, we demonstrate that small interfering RNAs (siRNAs) inhibit West Nile virus replication in vitro. Moreover, the administration of siRNAs to mice by hydrodynamic injection 24 h before challenge with an intraperitoneal inoculum of West Nile virus reduced the viral load and afforded partial protection from lethal infection. These data show the efficacy of the prophylactic use of siRNAs against a viral infection in vivo and suggest new strategies to combat West Nile virus.

Protection against West Nile Virus Infection in Mice after Inoculation with Type I Interferon-Inducing RNA Transcripts

West Nile virus (WNV) is a neurovirulent single stranded RNA mosquito-borne flavivirus, whose main natural hosts are birds, but it also infects humans and horses. Nowadays, no human vaccine is commercially available and clinical treatment is only supportive. Recently, it has been shown that RNA transcripts, mimicking structural domains in the non-coding regions (NCRs) of the foot-and mouth dise...

A Single siRNA Suppresses Fatal Encephalitis Induced by Two Different Flaviviruses

BACKGROUND Japanese encephalitis virus (JEV) and West Nile virus (WNV) are neurotropic flaviviruses that can cause acute encephalitis with a high fatality rate. Currently there is no effective treatment for these infections. METHODS AND FINDINGS We tested RNA interference (RNAi)-based intervention to suppress lethal JE and WN encephalitis in mice. To induce RNAi, we used either lentivirally e...

Mutation in West Nile Virus Structural Protein prM during Human Infection

A mutation leading to substitution of a key amino acid in the prM protein of West Nile virus (WNV) occurred during persistent infection of an immunocompetent patient. WNV RNA persisted in the patient's urine and serum in the presence of low-level neutralizing antibodies. This case demonstrates active replication of WNV during persistent infection.

Infection with Non-Lethal West Nile Virus Eg101 Strain Induces Immunity that Protects Mice against the Lethal West Nile Virus NY99 Strain

Herein we demonstrate that infection of mice with West Nile virus (WNV) Eg101 provides protective immunity against lethal challenge with WNV NY99. Our data demonstrated that WNV Eg101 is largely non-virulent in adult mice when compared to WNV NY99. By day 6 after infection, WNV-specific IgM and IgG antibodies, and neutralizing antibodies were detected in the serum of all WNV Eg101 infected mice...

Modulation of flavivirus population diversity by RNA interference.

To test the hypothesis that RNA interference (RNAi) imposes diversifying selection on RNA virus genomes, we quantified West Nile virus (WNV) quasispecies diversity after passage in Drosophila cells in which RNAi was left intact, depleted, or stimulated against WNV. As predicted, WNV diversity was significantly lower in RNAi-depleted cells and significantly greater in RNAi-stimulated cells relat...
