Induction Of Zika Virus-Specific Cd8+ T Cells By Means Of Dna Vaccine, Frank Gambino Jr.

Master's Theses

Zika virus (ZIKV) is a member of the virus family flaviviridae and is transmitted via Aedes aegypti mosquitos. Monoclonal antibodies against dengue virus have been found to cross-react with ZIKV but show no ability to neutralize it. Further studies have shown that Stat2-/- mice given plasma from dengue positive donors exhibit a heightened disease phenotype when challenged with ZIKV. Antibody dependent enhancement is theorized to cause such effect. The goal of this study was to design a plasmid which, when encoded, creates an antigen that will be used to stimulate exclusively CD8+ T cells. The gene sequence of NS3 was …

Cell Intrinsic Characteristics Of Cord Blood Naive Cd4 T Cells, Taylor Keller

Master's Theses

The neonatal immune system is functionally distinct from the adult immune system. Neonatal immune responses are less reactive than their adult counterparts, and as such, have an increased susceptibility to infection, resulting in increased duration and severity of disease. There is evidence that T-cells are partially responsible for the observed immunological differences between neonates and adults. Murine studies on neonatal immunity suggest that Th2 like responses predominate the neonatal immune system, an observation not found in the adult immune system. However, studies on human cord blood revealed that human neonates do not exhibit elevated Th2 like cytokines (with the exception …

Lidocaine Attenuates An Induced Inflammatory Response, Stephanie Zack

Master's Theses

Inflammation is common to the pathogenesis of a variety of diseases. Therapeutics which can regulate and reduce damaging inflammation are therefore valuable in the treatment of inflammation and inflammatory diseases.

One commonly used analgesic, recently identified as limiting inflammation, is lidocaine. Additionally, alternative, less toxic therapeutics like the snake venom peptides, Zep 3 and Zep 4, are thought to have anti-inflammatory effects. Yet a well-defined mechanism or cellular target for lidocaine or Zep peptides' anti-inflammatory effects has not been proposed.

We aimed to determine whether lidocaine and Zep peptides reduce the release of the proinflammatory cytokine, IL-1β, from activated human …

The Characterization Of Rna Content And Biogenesis Pathways Of Extracellular Vesicles That Have Been Implicated In The Pathogenesis Of Hiv-1 Associated Neurocognitive Disorders, Virginia Elizabeth Zwikelmaier

Master's Theses

Patients infected with HIV-1 adhering to Anti-Retroviral Therapy (ART) still suffer from a variety of neurocognitive, behavioral, and motor dysfunctions, collectively referred to has HIV-1 Associated Neurocognitive Disorders (HAND). Current research suggests the manifestations of HAND might in part be due to the dissemination of toxic HIV-1 components throughout the brain via extracellular vesicles (EVs). Our goal is to characterize these pathogenic EVs to begin to gain a better understanding of this EV-mediated pathology.

We took the first steps in developing a technique to assess the microRNA content of individual EVs but it needs to be heavily optimized to eliminate …
