Project description:Transcriptional responses in lungs of mice infected with Respiratory Syncytial Virus (RSV) were compared to a control and mock infections
Project description:In this dataset, we identify microRNAs and other ncRNAs in neuronal (SHSY5Y) cells following a 12h or 24h infection with Respiratory Syncytial Virus (RSV) or Measles virus (MeV) relative to mock treated neuronal cells
Project description:Stimulation of unmyelinated C-fibers is able to initiate host responses. In this study, we established the model of C fiber degenerated (KPCF) mice. KPCF mice were given respiratory syncytial virus (RSV) infection. We aimed to figure out the role of C fibers in RSV infection.
Project description:In this study we investigated whether there exists a genomic signature that can accurately predict the course of a respiratory syncytial virus (RSV) infection in hospitalized young infants. We used early blood microarray transcriptome profiles from 39 infants that were followed until recovery and of which the level of disease severity was determined retrospectively. Applying support vector machine learning on age by sex standardized transcriptomic data, an 84 gene signature was identified that discriminated hospitalized infants with eventually less severe RSV infection from infants that suffered from most severe RSV disease.
Project description:The respiratory epithelium is a polarised layer at the interface between the outside environment and deeper lung structures, overlaid by the epithelial lining fluid (ELF). This provides a mechanical and immunological barrier to inhaled particulates, such as viruses. Human respiratory syncytial virus (hRSV) is a major cause of disease in humans, and targets the respiratory epithelium. However, little is known of the disruption of the ELF proteome in the context of virus-driven respiratory illnesses. To address this, a proteomics approach was combined with an ex-vivo human airway epithelial model (HAE) to investigate the apical and basolateral secretome in hRSV-infected cultures. This demonstrated that several apically- and basolaterally-restricted proteins were subsequently secreted in both directions upon infection, while a number of proteins saw their apical/basolateral abundance ratios significantly altered. Furthermore, another 35 proteins were uniquely identified after hRSV treatment. Importantly, some of these changes were correlated in nasal aspirates (NA) from children with and without hRSV. This study showed that hRSV could affect airway secretions, and disrupted the directionality of the respiratory epithelium.
