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. The goal of this experiment was to use global gene expression profiling to understand swine lung host responses to pandemic H1N1 influenza A/Californica/04/2009 (CA04) virus infection and compare acute host responses across independent species. Four-week-old crossbred pigs (Sus Scrofa) were inoculated intratracheally with either 10^6 TCID50/pig egg-derived 2009 pandemic influenza A/California/04/2009 virus (n = 5) or mock inoculated with non-infectious cell culture supernatant (control; n = 4). Animals were euthanized on day 7 post-infection and lung samples were used for microarray.

Project description:The determinants of influenza transmission remain poorly understood. Swine influenza viruses preferentially attach to receptors found in the upper airways; however, most swine influenza viruses fail to transmit efficiently from swine to humans, and from human-to-human. The pandemic 2009 H1N1 (H1N1pdm) virus was a rare exception of a swine virus that acquired efficient transmissibility from human-to-human, and is reflected in efficient respiratory droplet transmission in ferrets. We hypothesize that virus-induced host responses in the upper airways correlate with airborne transmission in ferrets. To address this question, we used the H1N1pdm virus and swine influenza A/swine/Hong Kong/201/2010 (HK201) virus that has comparable titre in the ferret nasopharynx, but it exhibits differential transmissibility in ferrets via respiratory droplet route. We performed a transcriptomic analysis of tissues from the upper and lower respiratory tract from ferrets infected with either H1N1pdm or HK201 viruses using ferret-specific Agilent oligonucleotide arrays. We found differences in the kinetics of the innate immune response elicited by these two viruses that varied across tissues.

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.

Six-to-eight-week-old female BALB/c mice were anesthetized and inoculated with either 50 μl of phosphate-buffered saline (PBS; Mock) or with 10^6 pfu of pandemic H1N1 influenza A/California/04/2009 virus in a 50 μl volume, and whole lungs were collected at days 1, 3 and 5 post-inoculation. Lung samples from 9 animals for the infection group were used for array analysis, three animals per time point. Lung samples from 8 animals for the mock group were used for array analysis, three animals for the day 1 and 3 time points and 2 animals for the day 5 time point.

The goal of this experiment was to use global gene expression profiling to understand non-human primate lung cellular responses to pandemic H1N1 influenza A/California/04/2009 virus infection. Four-to-fifteen-year-old cynomologous macaques were infected with CA04 virus (n = 4) under anesthesia through a combination of intratracheal (4 ml), intranasal (0.5 ml per nostril), conjunctival (0.5 ml per eyelid) and oral (1 ml) routes with a suspension containing 10^6 TCID50/ml (total infectious dose was 7x10^6 TCID50). Animals were euthanized on 1 and 6 days post-inoculation (n = 2 per time point), and total RNA was extracted from lung samples and analyzed by microarray. Pooled RNA from lungs of uninfected animals served as the reference.

Project description:As a mild, highly contagious, respiratory disease, swine influenza always damages the innate immune systems, and increases susceptibility to secondary infections which results in considerable morbidity and mortality in pigs. Nevertheless, the systematical host response of pigs to swine influenza virus infection remains largely unknown. To explore these, a time-course gene expression profiling was performed to detect comprehensive analysis of the global host response induced by H1N1 swine influenza virus in pigs.
