A Mechanistic And Genomic Analysis Of Molluscum Contagiosum Virus Immune Evasion, Ian Benjamin Harvey
A Mechanistic And Genomic Analysis Of Molluscum Contagiosum Virus Immune Evasion, Ian Benjamin Harvey
Arts & Sciences Electronic Theses and Dissertations
Molluscum contagiosum virus (MCV) is a common human-specific poxvirus with a proclivity for
infecting children and the immune-compromised. A characteristic MCV infection is restricted to
the epidermal layers of the skin and can persist for weeks to years in an otherwise healthy
individual. The high clinical burden of MCV is at odds with our limited knowledge regarding how
it successfully evades the human immune response, which is in part due to the lack of an animal
model or cell line to propagate the virus. Through this dissertation, we have uncovered and
characterized a novel mechanism by which MC80, a protein …
Mass Spectrometry-Based Structural Proteomics: Methodology And Application Of Fast Photochemical Oxidation Of Proteins (Fpop), Ben Niu
Arts & Sciences Electronic Theses and Dissertations
The dissertation will be solely focused on using mass spectrometry to characterize protein high order structures (HOS), it emphasizes the use of hydroxyl radical footprinting (FPOP) coupled to bottom-up MS approach. A detailed background information about FPOP, and the corresponding method developments as well as applications will be covered.
The first chapter will be a comprehensive review regarding the FPOP. Following this, chapter 2, 3, and 4 will be focused on the method developments. Chapter 2 describes an isotope dilution GC-MS method to quantitate OH radicals in FPOP; chapter 3 describes the incorporation of Leu-enkephalin as reporter peptide for a …
Mapping Analyte-Signal Relations In Lc-Ms Based Untargeted Metabolomics, Nathaniel Guy Mahieu
Mapping Analyte-Signal Relations In Lc-Ms Based Untargeted Metabolomics, Nathaniel Guy Mahieu
Arts & Sciences Electronic Theses and Dissertations
The goal of untargeted metabolomics is to profile metabolism by measuring as many metabolites as possible. A major advantage of the untargeted approach is the detection of unexpected or unknown metabolites. These metabolites have chemical structures, metabolic pathways, or cellular functions that have not been previously described. Hence, they represent exciting opportunities to advance our understanding of biology. This beneficial approach, however, also adds considerable complexity to the analysis of metabolomics data - an individual signal cannot be readily identified as a unique metabolite. As such, a major challenge faced by the untargeted metabolomic workflow is extracting the analyte content …
