Project description:A mixed-aerosol pH1N1 (Cal04) challenge of rhesus macaques was establised to serve as a pre-clinical model for the evaluation of candidate vaccines. After characterizing the clinical signs and immune responses associated with pH1N1 challenge in naïve rhesus macaques, a follow-up study assessing 2 candidate vaccines was performed.

Project description:Background: The 2009 pandemic H1N1 influenza virus emerged in swine and quickly became a major global health threat. In mouse, non-human primate, and swine infection models, the pH1N1 virus efficiently replicates in the lung and induces pro-inflammatory host responses; however, whether similar or different cellular pathways were impacted by pH1N1 virus across independent infection models remains to be further defined. To address this, we have performed a comparative transcriptomic analysis of acute host responses to a single pH1N1 influenza virus, A/California/04/2009 (CA04), in the lung of mice, macaques and swine. Results: Despite similarities in the clinical course, we observed differences in inflammatory molecules elicited, and the kinetics of their gene expression changes across all three species. The retinoid X receptor (RXR) signaling pathway controlling pro-inflammatory and metabolic processes was differentially regulated during infection in each species, though the heterodimeric RXR partner, pathway associated signaling molecules, and gene expression patterns differed in each species. Conclusions: By comparing transcriptional changes in the context of clinical and virological measures, we identified differences in the host transcriptional response to pH1N1 virus across independent models of acute infection. Antiviral resistance and the emergence of new influenza viruses have placed more focus on developing drugs that target the immune system. Underlying overt clinical disease are molecular events that suggest therapeutic targets identified in one host may not be appropriate in another.

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.

Project description:We used the microarray data to analyze host cells response on A549 cells infected with Influenza A virus (A/Singapore/478/2009 (pH1N1)) The Influenza A virus (A/Singapore/478/2009 (pH1N1)) infected A549 cells were harvested at 2, 4, 6, 8 and 10 hpi and RNA extraction was performed using standard protocol as described by Affymetrix. The aim of this experiment is to analyze host response to Influenza A virus (A/Singapore/478/2009 (pH1N1)) infection.

Project description:In this study, we investigated the landscape of cardiac tissues collected at rapid autopsy from 7 SARS-CoV-2, 2 pH1N1, and 6 control patients using targeted spatial transcriptomics approaches. The main outcomes for the study were to profile rapid autopsy samples collected from the COVID-19, pH1N1 and normal, non-viral deaths to determine transcriptional changes between the different cohorts. Although SARS-CoV-2 was not detected in cardiac tissue, host transcriptomics showed upregulation of genes associated with DNA damage and repair, heat shock, and M1-like macrophage infiltration in the cardiac tissues of COVID-19 patients. The DNA damage present in the SARS-CoV-2 patient samples, were further confirmed by g-H2Ax immunohistochemistry. In comparison, pH1N1 showed upregulation of Interferon-stimulated genes (ISGs), in particular interferon and complement pathways, when compared with COVID-19 patients.
