Equine arteritis virus (EAV) has the unique ability to establish long-term persistent infection in the reproductive tract of stallions and be sexually transmitted. Previous studies showed that long-term persistent infection is associated with a specific allele of the CXCL16 gene (CXCL16S) and that persistence is maintained despite the presence of local inflammatory and humoral and mucosal antibody responses. Here, we performed transcriptomic analysis of the ampullae, the primary site of EAV persistence in long-term EAV carrier stallions, to understand the molecular signatures of viral persistence. We demonstrated that the local CD8+ T lymphocyte response is predominantly orchestrated …

The Deadly Influenza Virus And Its Changing Forms, Kayce Boggess
D.U.Quark
The influenza virus has plagued humans for centuries. Recently antiviral medications, which shorten the duration of the flu, have been introduced into society. These medications along with vaccinations, which try to give the body immunity before the virus strikes, help to stop the flu before it attacks the host. The virus, however, replicates using host cells and can slightly change itself with each replication, which over time could lead to a strain immune to the current antiviral medication and vaccines. However, using more preventative measures could help slow the changing strains of the flu virus. Using vaccines to stop the …
Membrane Microdomains As Platforms For Extra-Cellular Fusions, Michael Hantak
Membrane Microdomains As Platforms For Extra-Cellular Fusions, Michael Hantak
Dissertations
Life requires biological membranes. Membrane-enclosed compartments separate and unite through dynamic fission and fusion reactions. These are catalyzed processes that are central in organismal biogenesis. This dissertation focuses on extracellular membrane fusions, which are central to several processes. (1) Enveloped viruses enter cells through membrane fusions. (2) Extracellular vesicles (EVs) also deliver molecules into cells through membrane fusions. (3) Entire cells also fuse together, generating fertilized zygotes, skeletal muscles, and giant cell macrophages.Mechanisms of extracellular membrane fusion are poorly understood. This dissertation aimed to further define these mechanisms. We focused on regulatory cofactors, including tetraspanins, transmembrane proteins that cluster into …
Analysis Of The Thermal Stability Of A Diverse Panel Of Respiratory Syncytial Virus (Rsv) Strains, Darby Deford
Analysis Of The Thermal Stability Of A Diverse Panel Of Respiratory Syncytial Virus (Rsv) Strains, Darby Deford
Undergraduate Honors Thesis Collection
Respiratory syncytial virus (RSV) is a major respiratory pathogen of young infants and the elderly and is associated with upper and lower respiratory disease. Vaccine development for RSV has been hindered by poor immunogenicity in target populations, genetic and physical instabilities, and a legacy of vaccine-enhanced disease. The fusion and attachment proteins of RSV, F and G, have been seen to be responsible for inducing the majority of neutralizing antibodies. However, little remains known about how differences in RSV F and G affect virus replication and stability. In this thesis, we proposed to examine the replication and thermal stability of …

Equitable learning opportunities are critical to the goals of science education. However, major curriculum standards are vague on how to achieve equity goals, and educators must often develop their own resources and strategies to achieve equity goals. This study examines how educators used a comic book series designed to interest youth in virology as a way to make science more broadly appealing to their diverse students. We begin with the notion of Pedagogical Design Capacity, which describes a dynamic relationship between teachers and their tools and the ability for teachers to perceive and leverage affordances of artifacts as tools in …

Spiders (order Araneae, class Arachnida) are an important group of predatory arthropods in terrestrial ecosystems that have been recently identified as an untapped reservoir of single-stranded (ss)DNA viruses. Specifically, spiders harbour a diversity of ssDNA viruses encoding a replication-associated protein (Rep) within a circular genome. However, little is known about the ecology of novel circular Rep-encoding ssDNA (CRESS DNA) viruses. Here we investigated two CRESS DNA viruses recently identified in spinybacked orbweavers (Gasteracantha cancriformis), namely spinybacked orbweaver circular virus (SpOrbCV) 1 and 2. SpOrbCV-1 was detected in the majority (> 65 %) of spider specimens from all life …
Investigating The Antiviral Effects Of Vig-3 From Rainbow Trout, Shanee Herrington-Krause
Investigating The Antiviral Effects Of Vig-3 From Rainbow Trout, Shanee Herrington-Krause
Theses and Dissertations (Comprehensive)
Rainbow trout is the most farmed fish in Ontario, and thus is economically important to the province. Despite this, there is a lack of understanding regarding fish innate immunity, specifically with regards to interferon-stimulated genes (ISGs) and their antiviral effector functions. ISGs are the workhorses of the innate antiviral response, operating together to limit each step of virus replication. The Viral Hemorrhagic Septicemia Virus (VHSV) induced gene (Vig)-3 is a newly identified ISG within many fish species and is homologous to ISG-15 in mammals. It is a small ubiquitin-like protein inducible by type I interferon (IFN-I), and is suggested to …
