Ontology highlight
ABSTRACT: Differential expression was determined in Calu-3 cells between mock infected and infected with H1N1 influenza virus A/Netherlands/602/2009 at nine time points post-infection. As a comparison, cells were also infected with A/CA/04/2009 H1N1 influenza virus at 4 time points post-infection. Cells were infected at an MOI of 3.0. For the A/Netherlands/602/09-infected and mock-infected cells, samples were collected at 0, 3, 7, 12, 18, 24, 30, 36, and 48 hours post-infection (h.p.i.). For the A/California/04/2009-infected cells, samples were collected at 0, 12, 24, and 48 h.p.i. Samples were collected in triplicate.

Project description:Purpose of experiment was to perform transcriptomics on Calu- 3 cells infected with Influenza A/VN/1203/04. Calu-3 cells were infected with Influenza A/VN/1203/04, at MOI of 1.0. Cells samples were collected at 0, 3, 7, 12, 18, and 24 h post infection. Each infected sample was done in duplicate. (Duplicates are defined as 2 different wells, plated at the same time using the same cell stock for all replicates.)There is one time-matched mock for each time point from the same cell stock as rest of samples. Culture medium (the same as what the virus stock is in) was used for the mock infections. The NIAID Systems Virology Center
Project description:Comparison of the host response to VN1203 infection in three different strains of mice: Wild-type C57BL/6J mice, IDO1 KO mice and TNFRSF1B KO. Groups of 6-week-old mice were infected with A/Vietnam/1203/04 H5N1 influenza virus at a dose of 10^3 PFU or mock infected. Mice were euthanized on days 2 and 6 post-infection to measure virus load and isolate samples for measurement of virus load, lung pathology, transcriptional analysis and proteomics analysis. Mock-infected animals were also harvested at each time point. Mice were weighed every 24 hours to measure general disease progression and any mouse approaching 30% weight loss was euthanized.
Project description:This study used virological, histological, and global gene expression from an experimental murine model of influenza infection to study the contribution of a specific mutation in the PB1-F2 protein (PB1-F2 N66S) of influenza A to viral pathogenesis. 6-8 week old, wild-type, female, C57Bl/6 mice were inoculated individually with 30 μl (10^4 PFU) of virus (recombinant influenza A/WSN/33 carrying the PB1 gene segment from A/Hong Kong/156/97 (H5N1) or a PB1 mutant recombinant virus resulting in an amino acid change at position 66 in the PB1-F2 protein [N66S]) in phosphate-buffered saline (PBS) containing penicillin-streptomycin and bovine serum albumin (PBS-BA-PS). A total of 10^4 PFU of virus was given in all inoculations. Control mice were given PBS-BA-PS. Lung samples were taken for microarray analysis at 12h, 1d, 3d, and 5d post-infection (n=3 animals per group at each time point for virus infected animals; n=2 animals per time point for mock-infected animals).
Project description:Over the last decade, more than half of humans infected with highly pathogenic avian influenza (HPAI) H5N1 viruses have died, and yet virus-induced host signaling has yet to be clearly elucidated. Airway epithelia are known to produce inflammatory mediators that contribute to HPAI H5N1-mediated pathogenicity, but a comprehensive analysis of the host response in this cell type is lacking. Here, we leveraged a systems biology method called weighted gene correlation network analysis (WGCNA) to identify and statistically validate signaling sub-networks that define the dynamic transcriptional response of human bronchial epithelial cells after infection with influenza A/Vietnam/1203/2004 (H5N1, VN1203). A detailed examination of two sub-networks involved in the immune response and keratin filament formation revealed potential novel mediators of HPAI H5N1 pathogenesis, and additional experiments validated upregulation of these transcripts in response to VN1203 infection in C57BL/6 mice. Using emergent network properties, we provide fresh insight into the host response to HPAI H5N1 virus infection, and identify novel avenues for perturbation studies and potential therapeutic intervention of fatal HPAI H5N1 disease. Calu-3 cells were infected with VN1203 influenza virus and profiled at 0, 3, 7, 12, 18, and 24 hours post infection. There are 3 mock and infected replicates for each time point.
Project description:Purpose of experiment was to compare transcriptomics of 2B4 cells (clonal derivative of Calu-3 cells) infected with either icSARS CoV, icSARS-deltaNSP16 or icSARS ExoNI mutants. 2B-4 cells (clonal derivatives of Calu-3 cells) were infected with either icSARS CoV, icSARS deltaNSP16 or icSARS ExoNI. Wild type and deltaNSP16 mutant infections were at an MOI of 5 while the ExoNI infections were at an MOI of 1. Cells samples were collected at 0, 7, 12, 24, 36, 36, 48, 60 or 72h post infection. Each infected sample was done in triplicate. (Triplicates are defined as 3 different wells, plated at the same time using the same cell stock for all replicates.) There are triplicate time-matched Mock for each time point from the same cell stock as rest of samples. Culture medium (the same as what the virus stock is in) was used for the Mock infections.
Project description:This study used virological, histological, and global gene expression data to compare the virulence of two 2009 pH1N1 isolates from human (A/California/04/2009) and swine (A/swine/Alberta/25/2009) to that of a 1918-like classical swine influenza virus (A/swine/Iowa/1930) in a pig model of infection. The overall goal of this study was to characterize the clinical, histological, virological and global gene expression responses to three distinct influenza A isolates in an experimental pig model of influenza infection. We compared the pathogenesis of two pH1N1 viruses, one derived from a human patient (A/CA/04/09 [CA09]) and the other from swine (A/swine/Alberta/25/2009 [Alb09]), with that of the 1918-like classical swine influenza virus (A/swine/Iowa/1930 [IA30]) in the pig model. Both pH1N1 isolates induced clinical symptoms such as coughing, sneezing, decreased activity, fever, and labored breathing in challenged pigs, but IA30 virus did not cause any clinical symptoms except fever. Although both the pH1N1 viruses and the IA30 virus caused lung lesions, the pH1N1 viruses were shed from the nasal cavities of challenged pigs whereas the IA30 virus was not. Microarray was used to assess global gene expression in the lungs at 3 and 5 days post-infection. Crossbred pigs fwere obtained from a healthy herd free of SIV and porcine reproductive and respiratory syndrome virus. These studies included two experiments: the classical H1N1 SIV (IA30) study was completed at Kansas State University's biosafety level 2 (BSL-2) facility in compliance with the Institutional Animal Care and Use Committee at Kansas State University, and the pH1N1 virus study was completed at the Central States Research Center (CSRC), Inc., BSL-3 facility (Oakland, NE), in compliance with the Institutional Animal Care and Use Committee at CSRC. In each experiment, 10 pigs were inoculated with noninfectious cell culture supernatant as controls. For the classical H1N1 SIV experiment, 10 4-week-old crossbred pigs were inoculated intratracheally with 10^6 50% tissue culture infective doses (TCID50)/pig of egg-derived IA30 virus. For the pH1N1 virus experiment, 10 4-week-old crossbred pigs were inoculated intratracheally with 10^6 TCID50/pig of either egg-derived CA/09 or Alb/09 virus. Five animals per group were euthanized at 3 and 5 days postinfection (dpi), respectively.
