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. At the age of day 35, 15 pigs were randomly allocated to the non-infected group and 15 to the infected group. Each piglet of the infected group was intranasaly challenged with A/swine/Hubei/101/2009(H1N1) strain and Each piglet of the non-infected group was treated similarly with an identical volume of PBS as control.

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:Swine H1N1 influenza virus and streptococcus suis serotype 2 (SS2) are two important contributors to the porcine respiratory disease complex, which have significant economic impacts. Clinically, swine influenza virus and swine streptococcus suis co-infection is common, which will increase the mortality. However, the pathogenesis of the co-infection remains largely unkown. To explore it, gene expression profiling was to performed to detect comprehensive analysis of the global host response induced by H1N1 virus infection alone, SS2 infection alone, H1N1-SS2 co-infection and PBS control.

Project description:In recent years, the roles of microRNAs playing in the regulation of influenza viruses replication caused researchers' much attenion. However, much work focused on the interactions between human, mice or chicken microRNAs with human or avian influenza viruses rather than the interactions of swine microRNAs and swine influenza viruses. To investigate the roles of swine microRNAs playing in the regulation of swine influenza A virus replication, the microRNA microarray was performed to identify which swine microRNAs were involved in swine H1N1/2009 influenza A virus infection.

Project description:Background: Swine influenza is a highly contagious viral infection in pigs affecting the respiratory tract that can have significant economic impacts. Streptococcus suis serotype 2 is one of the most important post-weaning bacterial pathogens in swine causing different infections, including pneumonia. Both pathogens are important contributors to the porcine respiratory disease complex. Outbreaks of swine influenza virus with a significant level of co-infections due to S. suis have lately been reported. In order to analyze a global response to the dual infection, we carried out a comprehensive gene expression profiling using a microarray approach to study the swine tracheal epithelial (NPTr) cell response to a co-infection with H1N1 swine influenza virus (swH1N1) and S. suis serotype 2. Results: Gene clustering showed that the swH1N1 and swH1N1/S. suis infections modified the expression of genes in a similar manner. Additionally, infection of NPTr cells by S. suis alone did not result in many differentially expressed genes compared to mock-infected cells. However, some important genes coding for inflammatory mediators, such as chemokines, interleukins, cell adhesion molecules and eicosanoids, were significantly upregulated in the presence of both pathogens comparing to infection with each pathogen taken individually. This synergy may also be the consequence of an increased adhesion/invasion of epithelial cells previously infected by swH1N1, as recently reported. Conclusion: In a co-infection situation, influenza virus would replicate in the respiratory epithelium inducing an inflammatory infiltrate comprised of mononuclear cells and neutrophils. Despite that these cells are unable to phagocyte and kill S. suis, they are highly activated by this pathogen. S. suis is not considered a primary pulmonary pathogen, but an exacerbated production of pro-inflammatory mediators during a co-infection with influenza virus may be of critical importance in the pathogenesis and outcome of this respiratory disease complex. Total RNA obtained from NPTr cells infected with S. suis, H1N1, or S. suis & H1N1. Four replicates in both groups.

The goal of this experiment was to use global gene expression profiling to understand mouse lung cellular responses to pandemic H1N1 influenza A/Californica/04/2009 virus 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.
