Investigating The Antiviral Effects Of Vig-3 From Rainbow Trout, Shanee Herrington-Krause Jan 2019

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 …


Using Rainbow Trout Cell Lines As A Model For Understanding The Innate Anti-Fv3 Immune Response, Graeme Robert Jones Lisser Jan 2017

Using Rainbow Trout Cell Lines As A Model For Understanding The Innate Anti-Fv3 Immune Response, Graeme Robert Jones Lisser

Theses and Dissertations (Comprehensive)

Ranavirus infections are on the rise and have been implicated in numerous species die-offs across the globe. Frog virus 3 (FV3) is the type-species of the genus, yet the immune mechanisms governing susceptibility remain poorly understood. Arguably the most important immune response to infection is the type I interferon (IFN) response. Type I IFNs trigger an “antiviral state” in host cells via the production of numerous interferon-stimulated genes (ISGs) that act to inhibit virus replication in various way, including the induction of apoptosis. Apoptosis is an important antiviral defense mechanism to limit virus replication within infected cells. This study employed …
