Pathological Consequences Of Pdi Oxidoreductase Activity On Viral Protein Maturation, Nicolas Chamberlain

Graduate College Dissertations and Theses

The influenza A virus (IAV) causes severe respiratory illness in humans. Current treatments are rapidly becoming ineffective due to the emergence of viral resistance to available therapies such as oseltamivir and zanamivir. Given the impact of this virus there is an urgent need to explore novel targets for new treatments less susceptible to viral mutation; targeting host proteins utilized by the virus may avoid these limitations. It has been shown in vitro that interactions with host ER based protein disulfide isomerases (PDIs) are required for specific IAV proteins to reach their functional conformations. The viral proteins hemagglutinin (HA) and neuraminidase …

Key Virus-Host Interactions Required For Arenavirus Particle Assembly And Release, Christopher Michael Ziegler

Graduate College Dissertations and Theses

Viruses are infectious agents that must infect the cells of living organisms in order to reproduce. They have relatively simple genomes which encode few proteins but can compensate for their simplicity by hijacking components of their cellular hosts. Arenaviruses, a family of zoonotic viruses carried by rodents, encode only 4 proteins. One of these proteins, Z, is responsible for several functions during the virus life cycle including driving the formation and release of new virus particles at the plasma membrane of infected cells. Relatively little is known about how this viral protein is regulated or the complement of host proteins …

Hiv-1-Induced Cell-Cell Fusion: Host Regulation And Consequences For Viral Spread, Menelaos Symeonides

Graduate College Dissertations and Theses

Human immunodeficiency virus type 1 (HIV-1) is a human retrovirus of the lentivirus subgroup which primarily infects T cells and macrophages, and causes acquired immune deficiency syndrome (AIDS). Since its emergence in the early 1980s, HIV-1 has caused a global pandemic which is still responsible for over one million deaths per year, primarily in sub-Saharan Africa.

HIV-1 has been the subject of intense study for over three decades, which has resulted not only in major advances in cell biology, but also in numerous drug treatments that effectively control the infection. However, cessation of treatment always results in reemergence of the …
