Vircy-Seq : A Protocol For Characterizing Viral Activity, Tyler James Dion
Vircy-Seq : A Protocol For Characterizing Viral Activity, Tyler James Dion
Legacy Theses & Dissertations (2009 - 2024)
The main purpose of pharmaceutical production is to produce safe effective medicine for patient use. In an effort to ensure patient safety constant surveillance for viruses takes place. The detection of a viral nucleic acid in a pharmaceutical production setting results in investigations to assess its infectious potential. This is an intensive, expensive process that entails many tests such as the observation of hemadsorption, cytopathic effects (CPE), and more. These tests are typically specific and only capture certain viruses, as factors like CPE can only be observed in some viral species. A new investigational method that is effective on all …

T-Cell Antigen Receptors In Multiple Sclerosis, Lisa Lanée Keyes Jones
Biomedical Sciences Theses & Dissertations
Multiple Sclerosis (MS) is T-cell mediated autoimmune disease characterized by inflammation, demyelination, and degeneration of axons in the brain and spinal cord. A T cell-mediated immune response in MS is directed against myelin components and possibly other antigens in genetically susceptible individuals and is triggered by a viral infection. The T-cell antigen receptor (TCR) on T cells is responsible for antigen recognition and determines specificity. Our overall hypothesis is to determine whether clonally expanded T cells in patients with MS recognize viral or self-antigens and to determine whether molecular mimicry is involved in the development of the disease. To study …
Characterization Of The Role Of The Replicase And Quasispecies Diversity In Flaviviral Evolution And Host Adaptation, Haley Caldwell
Characterization Of The Role Of The Replicase And Quasispecies Diversity In Flaviviral Evolution And Host Adaptation, Haley Caldwell
Legacy Theses & Dissertations (2009 - 2024)
Flaviviruses include several emerging and re-emerging arboviruses that cause millions of infections each year. Although relatively well-studied, much remains unknown regarding the mechanisms and means by which these viruses adapt to different hosts and rapidly alternate between hosts. Different aspects of flaviviral biology impact host switching, viral fitness, and the generation of viral diversity during genome replication by the NS3 and NS5 proteins. Together these factors may impact host plasticity.

Rift Valley fever virus (RVFV) is a mosquito-borne RNA virus that infects humans and livestock in sub-Saharan Africa and the Arabian peninsula, causing disease ranging from a mild flu-like illness to liver damage, blindness, hemorrhagic fever, death, and, especially in livestock animals, high rates of abortive pregnancies. There is no approved vaccine for RVFV, and as a disease with a high rate of spread that causes severe illness, it is listed as a Category A pathogen by the USA CDC. A better understanding of RVFV’s molecular virology will be instrumental to combating RVFV as climate change causes its mosquito host …

West Chester University Master’s Theses
Influenza A virus (IAV) is a highly infectious pathogen responsible for causing severe respiratory illness and death in humans and animals worldwide. Due to highly effective strategies to negate host antiviral defenses, IAV leads to the death of nearly all infected cells. Furthermore, IAV induces high levels of genome-damaging oxidative stress within infected cells and suppresses the cellular mismatch repair (MMR) mechanism, thereby inhibiting expression of key antiviral genes, which further contributes to cell death. However, recent studies have demonstrated that a subset of respiratory epithelial cells, called club cells, are able to non-lytically clear IAV and continue to survive …
