Pneumovirus Infections: Understanding Rsv And Hmpv Entry, Replication, And Spread, Jonathan T. Kinder
Theses and Dissertations--Molecular and Cellular Biochemistry
Pneumoviruses including human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) are significant causes of respiratory tract infections globally. Children, elderly, and immunocompromised patients are at the greatest risk for developing severe infections, which can have devastating outcomes. Although these viruses are ubiquitous with significant impacts on human health, there are no antivirals or vaccines available. The only FDA approved therapy is a monoclonal antibody for RSV, given prophylactically during the infectious season, and this treatment is only available for high risk infants. The work presented in this thesis aims to increase our understanding of how these viruses enter, replicate, and …

Human metapneumovirus (HMPV) causes significant upper and lower respiratory disease in all age groups worldwide. The virus possesses a negative-sense single-stranded RNA genome of approximately 13.3 kb encapsidated by multiple copies of the nucleoprotein (N), giving rise to helical nucleocapsids. In addition, copies of the phosphoprotein (P) and the large RNA polymerase (L) decorate the viral nucleocapsids. After viral attachment, endocytosis, and fusion mediated by the viral glycoproteins, HMPV nucleocapsids are released into the cell cytoplasm. To visualize the subsequent steps of genome transcription and replication, a fluorescence in situ hybridization (FISH) protocol was established to detect different viral RNA …
