Phosphoproteomic characterization of Streptococcus pneumoniae and Influenza A virus synergism

ABSTRACT: Our understanding of the synergism between S. pneumoniae and influenza virus remains incomplete. The classic dogma has been that influenza attenuates the host innate immunity and increase the susceptibility to subsequent bacterial infection. Therefore, the majority of current studies have been focusing on the interaction of S. pneumoniae and influenza in the context of host cells. By contrast, in this study, we set out to investigate the response of pneumococcus alone to virus infection. Our hypothesis was that prior to causing any damages to host cells, influenza may have induced (lethal) changes to pneumococcus cell itself. Indeed, a very recent evidence has shown that direct viral treatment to pneumococcus will increase its adhesion to macrophage cells. Here, using quantitative phosphoproteomic approach, we attempt to investigate the global alterations of S. pneumoniae phosphorylation by influenza virus challenge, and provide a landscape of synergism between the IAV and pneumococcus.

Influenza virus infection leads to global cardiac proteome remodeling during convalescence

Project description:Influenza virus infection leads to global cardiac proteome remodeling during convalescence MTD project_description "Influenza virus infections lead to more than 500,000 hospitalizations in the U.S. every year. Patients with cardiovascular diseases have been shown to be at high risk of influenza mediated cardiac complications. Importantly, recent reports have provided clinical data supporting a direct link between laboratory-confirmed influenza virus infection and adverse cardiac events. However, the molecular mechanisms of how influenza virus infection induces detrimental cardiac changes, even after resolution of the pulmonary infection, is completely unknown.

High body temperature increases gut microbiota-dependent host resistance to influenza A virus and SARS-CoV-2 infection (Hamster)

Project description:While a common symptom of influenza and coronavirus disease 2019 (COVID-19) is fever, its physiological role on host resistance to viral infection remains less clear. Here, we demonstrate that exposure of mice to the high ambient temperature of 36 °C increase host resistance to viral pathogens including influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). High heat-exposed mice increase basal body temperature over 38 °C to enable more bile acids production in a gut microbiota-dependent manner. The gut microbiota-derived deoxycholic acid (DCA) and its plasma membrane-bound receptor Takeda G-protein-coupled receptor 5 (TGR5) signaling increase host resistance to influenza virus infection by suppressing virus replication and neutrophil-dependent tissue damage. Furthermore, the DCA and its nuclear farnesoid X receptor (FXR) agonist protect Syrian hamster from lethal SARS-CoV-2 infection. Moreover, we demonstrate that certain bile acids are reduced in the plasma of COVID-19 patients who developed moderate I/II disease compared with minor illness group. These findings uncover an unexpected mechanism by which virus-induced high fever increases host resistance to influenza virus and SARS-CoV-2 in a gut microbiota-dependent manner.

Streptococcus pneumoniae infection and murine hearat proteome

Project description:For the last two decades, the three most common causes of death world-wide have been ischemic heart disease, cerebrovascular disease and respiratory tract infections; the latter being caused mainly by the influenza virus and the bacterial pathogen Streptococcus pneumoniae (Spn). Reports through this period of time have shown that elderly patients admitted to the hospital for severe community-acquired pneumonia (CAP), experience ~10-25% mortality rates and up to 40% of them expired within one year. A key contributing factor for the observed high mortality rate are the major adverse cardiac events (MACE) that occur during hospitalization and convalescence9. Notably, during severe pneumococcal infections, Spn, the most common cause of CAP, has been shown to be capable of myocardial invasion, induction of cardiomyocyte death, and disruption of cardiac contractility. In addition, changes to heart functionality have also been reported after influenza infection in humans, however the mechanisms for this remain unclear.

Extracellular Matrix Proteolysis by MT1-MMP is Associated with Influenza-Related Mortality

Project description:The balance between protecting tissue integrity and efficient immune response is critical for host survival. Here we investigate the role of extracellular matrix (ECM) proteolysis in achieving this balance in the lung during influenza virus infection using a combined genomic and proteomic approach. We followed the transcriptional dynamics and ECM- related responses in a mouse model of influenza virus infection, integrated with whole tissue imaging and functional assays. Our study identifies MT1-MMP as a prominent host-ECM-remodeling collagenase in influenza virus infection. We show that selective inhibition of MT1-MMP-driven ECM proteolysis protects the tissue from infection-related structural and compositional damage. Inhibition of MT1-MMP did not significantly alter the immune response or cytokine expression, indicating its dominant role in ECM remodeling. We demonstrate that the available treatment for influenza virus (Tamiflu/ Oseltamivir) does not prevent lung ECM damage and is less effective than anti-MT1-MMP treatment in influenza virus and Streptococcus pneumoniae coinfection paradigms. Importantly, combination therapy of Tamiflu with anti-MT1-MMP shows a strong synergistic effect and results in complete recovery in mice. This study highlights the importance of tissue tolerance agents for surviving infectious diseases, and the potential of such host-pathogen therapy combination for respiratory infections.

Streptococcus pneumoniae and IAV co infection induces altered polyubiquitination in A549 cells

Project description:Epithelial cells are the first line of defense within the lung. Disruption of the epithelial barrier by pathogens enables the systematic dissemination of bacteria or viruses within the host, leading to severe diseases with fatal outcomes. Thus, the lung epithelium can be damaged by seasonal and pandemic influenza A viruses. Influenza A virus infection induced dysregulation of the immune system is beneficial for the dissemination of bacteria to the lower respiratory tract, causing bacterial and viral co-infection. Host cells regulate protein homeostasis and the response to different stimuli, for instance pathogen infections, by post translational modification of proteins. Aside from protein phosphorylation, ubiquitination of proteins is an essential regulatory tool in virtually every cellular process, such as protein homeostasis, the host immune response, cell morphology, and in clearing of cytosolic pathogens. Here, we analyzed the proteome and ubiquitinome of A549 cells in response to Streptococcus pneumoniae D39 Δcps and influenza A virus H1N1 as well as bacterial and viral co-infection. Pneumococcal infection induced alterations in the ubiquitination of proteins involved in the organization of the actin cytoskeleton and Rho GTPases, but had minor effects on the abundance of host proteins. H1N1 infection is reflected by an anti-viral state of A549 cells. Finally, co infection resembled the imprints of both infecting pathogens with a minor increase in the observed alterations in protein and ubiquitination abundance.

investigation of the pathogenesis of H1N1 influenza virus and swine streptococcus suis serotype 2 co-infection in pigs by microarray analysis

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.
