Project description:Human metapneumovirus (HMPV) is a primary causative agent of acute lower respiratory tract infections. We used single cell RNA-sequencing (scRNA-seq) to assess lung immune profiles in a mouse model of HMPV infection.
Project description:This series includes 1 microarray used to detect a human metapneumovirus strain associated with critical respiratory illness in an elderly male with leukemia (Chiu, et al 2006) Keywords: viral detection
Project description:In vitro infection experiment with genetically modified human metapneumovirus (HMPV) to study the function of the viral small hydrophobic (SH) protein.
Project description:Background. Human Metapneumovirus (HMPV) and Respiratory Syncytial Virus (RSV), are responsible for respiratory diseases mostly in children. In spite of the resemblance between these two pneumoviruses, they elicit a different extent of immune response. miRNAs are small non coding RNAs that regulate gene expression and are involved in numerous cellular processes including the immune system. Methodology. Human monocyte-derived dendritic cells (moDC) were differentiated from peripheral blood mononuclear cells and infected at an MOI of 3 for 24h. RNA was isolated to analyze the miRNAs transcription by high throughput sequencing using illumina technology. Principal findings. Infection with HMPV up-regulated the expression of hsa-miR-4448, while RSV infection induced significant expression of hsa-miR-30a-5p, hsa-miR-182-5p, hsa-miR-1913, hsa37, miR-4448 and hsa-miR-4634. Conclusions/Significance. In human monocyte derived dendritic cells (moDC), RSV and HMPV induced different profiles of miRNA expression. Understanding the changes of miRNA expression profiles by RSV and HMPV in immune cells will further our understanding of the differential immune response induced by these respiratory viruses
