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.
Project description: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.
Project description:The purpose is to obtain samples for mRNA, miRNA, proteomics, lipidomics, metabolomics, and histopathology analysis in mouse cortex infected with wild-type West Nile virus (WNV; WNV-NY99 382), and mutant WNV-E218A (WNV-NY99 382 E218A 2 nt).

Project description:West Nile virus (WNV) is a mosquito-borne RNA flavivirus and the cause of more than 31,000 cases in the USA from 1999-2011 including 1, 262 fatalities. WNV infections are typically asymptomatic, but some patients, especially the elderly and immunocompromised, may experience severe neurological disease and even death. Control of WNV infection by the immune system is multifactorial. We profiled antibody, cytokine responses and gene expression from a stratified cohort of WNV subjects to define immune responses that contribute to disease severity and outcome. Differential gene expression by human PBMCs from asymptomatic and severe patients with WNV infection were generated by microarray.
