A Mouse Model of Chronic West Nile Virus Infection

ABSTRACT: Here, we characterize the RIX line CC(032x013)F1, which serves as a mouse model of chronic WNV infection. While studies using C57BL/6 mice have shown that WNV RNA can persist in the CNS up to 3 months post infection in a limited fraction of mice (Appler et al., 2010), to date there is a lack of a robust mouse model of chronic West Nile virus infection that can be used to elucidate the immune responses associated with this viral persistence and chronicity of symptoms described in human patients. Here, we characterize this line in comparison with lines showing either no disease symptoms or significant disease, and suggest a mechanism by which WNV infection can become chronic through alterations in immune responses. Microarrays were performed on spleen samples from mice collected at days 7,12,21,28 post-infection with west nile virus or from time-matched mock-infected animals.

Global gene expression in response to West Nile virus in mouse spleen and liver

Project description:Purpose of this experiment was to further understand how innate immune defenses impact host response and West Nile virus tissue tropism. This study examined host-transcriptional response to West Nile virus in permissive and nonpermissive tissues using wildtype mice and mice with genetically altered interferon signaling pathways. Age-matched six to twelve week old mice were inoculated subcutaneously in the left rear footpad with 100 PFU of West Nile virus isolate TX 2002-HC (WNV-TX) in a 10 microL inoculum diluted in Hanks balanced salt solution (HBSS) supplemented with 1% heat-inactivated FBS. Mice were monitored daily for morbidity and mortality. Expression oligonucleotide arrays were performed on RNA isolated from spleen and liver tissues from strain and time-matched mock infected mice (n=2) and WNV-TX infected wild type (WT; n=3; day 4 post-infection), Ips-1-/-(n=3; day 4 post-infection), Ifnar-/- (n=3; day 2 post-infection), and Ips-1-/-xIfnar-/- (DKO; n=3; day 4 post-infection) mice.

Gene Expression Analysis in the Thalamus and Cerebrum of Horses Experimentally Infected with West Nile Virus

Project description:The purpose of this experiment was to further our understanding of gene expression in the central nervous system (thalamus and cerebrum) after exposure to West Nile virus. To that end, three different analyses were performed. The first examined differences in gene expression between horses not vaccinated and exposed to WNV and normal control horses (exposure). The second examined differences in gene expression between horses not vaccinated and exposed to WNV and horses vaccinated and exposed to WNV (survival). And the third examined differences between the nonvaccinated cerebrum and nonvaccinated thalamus of horses exposed to WNV (location). Six conditions- Gene expression in the thalamus and cerebrum of three different groups of horses (Non-vaccinated horses exposed to West Nile virus, Vaccinated horses exposed to West Nile virus, normal horses not exposed to West Nile virus). Biological replicates- 6 normal cerebrums, 6 normal thalamus, 6 vaccinated and exposed cerebrums, 6 vaccinated and exposed thalamus, 6 non-vaccinated and exposed cerebrum, 6 non-vaccinated and exposed thalamus.
