Development Of Vaccines And Antivirals Against Zika Virus, Aryamav Pattnaik
Development Of Vaccines And Antivirals Against Zika Virus, Aryamav Pattnaik
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
The re-emergence of Zika virus (ZIKV), an arbovirus, poses a major global human health concern because of its ability to cause congenital abnormalities and neurological diseases. While many candidate vaccines and antiviral drugs are in the developmental pipeline, none have been approved for use against ZIKV infection. This dissertation describes the characterization of one vaccine and two antiviral drug candidates against ZIKV infection. A bacterial ferritin-based nanoparticle vaccine, termed zDIII-F, is designed to display multiple copies of ZIKV E protein domain III on its surface. These stable nanoparticles are shown to induce robust antibody-mediated protection against lethal ZIKV infection in …
Sodium Pyruvate Ameliorates Influenza A Virus Infection In Vitro And In Vivo, Jessica M. Reel
Sodium Pyruvate Ameliorates Influenza A Virus Infection In Vitro And In Vivo, Jessica M. Reel
Graduate Theses/Dissertations
Pyruvate is produced in duplicate at the end of glycolysis in addition to ATP and NADH. Pyruvate is the metabolite of choice in most cells, whether obtained exogenously or endogenously. Recently we found that the addition of pyruvate’s conjugate base, sodium pyruvate, to cell culture media dampened the immune response to influenza A virus (IAV) infection in cultured innate immune cells. Thus, I decided to investigate the mechanism and potential for treatment of IAV. In vitro using bone marrow derived macrophages that were infected with IAV we found that adding sodium pyruvate to the media decreased immune signaling pathways through …
The Intellectual Property Of Covid-19, Ana Santos Rutschman
The Intellectual Property Of Covid-19, Ana Santos Rutschman
All Faculty Scholarship
The response to COVID-19 is indissolubly tied to intellectual property. In an increasingly globalized world in which infectious disease pathogens travel faster and wider than before, the development of vaccines, treatments and other forms of medical technology has become an integral part of public health preparedness and response frameworks. The development of these technologies, and to a certain extent the allocation and distribution of resulting outputs, is informed by intellectual property regimes. These regimes influence the commitment of R&D resources, shape scientific collaborations and, in some cases, may condition the widespread availability of emerging technologies. As seen throughout this chapter, …
Development Of Novel Zika And Anthrax Viral Nanoparticle Vaccines, Elizabeth Henderson
Development Of Novel Zika And Anthrax Viral Nanoparticle Vaccines, Elizabeth Henderson
KGI Theses and Dissertations
Vaccines protect against numerous infectious diseases and prevent millions of deaths annually, but there are still many infectious diseases for which no licensed vaccine exists. Developing a new vaccine requires balancing safety and efficacy, and viral nanoparticle (VNP) vaccines possess both of these characteristics. The work herein demonstrates how tobacco mosaic virus (TMV) nanoparticles can serve as a platform to create candidate vaccines for Zika virus (ZIKV) and anthrax. In the first study, a ZIKV-specific epitope was genetically fused to TMV to create a safe and inexpensive vaccine that proved highly immunogenic in mice and led to the discovery of …

Here we report the results of an investigation into the possibility that one mechanism responsible for the establishment of persistent human immunodeficiency virus infection is an early regulatory T (Treg) cell response that blunts virus- specific responses. Using the simian immunodeficiency virus (SIV)–infected rhesus macaque model, we show that, indeed, viral replication and immune activation in lymphatic tissue drive a premature immunosuppressive response, with dramatic increases in the frequencies of CD4+CD25+FOXP3+ Treg cells, transforming growth factor–β1+ cells, interleukin–10+ cells, and indoleamine 2,3-dioxygenase+CD3+ cells.When we compared SIV infection with rhesus cytomegalovirus (RhCMV) …
