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

ABSTRACT: 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.

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.

Small RNA profiling of extracellular vesicles secreted by A549 cells infected with West Nile virus and treated with interferon alpha

Project description:The goal of this study is to determine if infection with flavivirus (West Nile virus) and action of proinflamatory cytokine interferon alter incorporation of host RNAs into extracellular vesicles secreted by human cells.

scRNA-seq of peripheral blood from West Nile Virus-infected patients

Project description:We profile the peripheral blood of patients infected with West Nile Virus with divergent disease-trajectories (West Nile Encephalitis, West Nile Fever, and asymptomatic) during relatively acute infection and at a convalescent timepoint (~90-days later) using single-cell RNA sequencing in an effort to uncover determinants of disease progression and flesh out the landscape of infection. In the blood of the infected patients, stratified cell-states involved in acute viral infection resolve into more homogenous states at the follow-up blood draws, A dramatic shared transcriptional shift between the primary blood-draws during acute infection and the 90-day follow-ups in all observed compartments allows us to highlight multiple cell-type and cell-state-specific patterns of gene expression.

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.
