Biological And Computational Studies Of The Structure And Function Of Pul103, A Human Cytomegalovirus Tegument Protein, Ashley N. Anderson
Wayne State University Dissertations
Human cytomegalovirus (HCMV) is an enveloped, single segment, double-stranded DNA virus. HCMV infection causes disease in immunocompromised (HIV patients, transplant recipients) and immunodeficient (fetuses, neonates) populations. Current treatments are effective but are either limited in use or can lead to organ damage and/or antiviral resistance, and no vaccines are available. Additional antiviral targets are needed. HCMV pUL103 is a potential antiviral target. pUL103 is a conserved herpesvirus protein present in the tegument, layer of proteins and RNA between the envelope and capsid of HCMV virions. pUL103 helps reorganize cellular secretory machinery (Golgi, endosomes) to form the cytoplasmic virion assembly compartment …
The Role Of Neurokinin Receptors And Satellite Glial Cells In Herpes Simplex Virus 1 Latency, Andrew Jerome
The Role Of Neurokinin Receptors And Satellite Glial Cells In Herpes Simplex Virus 1 Latency, Andrew Jerome
Wayne State University Dissertations
The ability of herpes simplex virus 1 (HSV-1) to establish a lifelong infection in neurons of the trigeminal ganglion (TG) make it a constant public health threat. Viral reactivation from its latent state is currently the leading cause of viral induced blindness in the United State, as well as the leading cause of herpes simplex encephalitis. Unfortunately, how the virus is able to both establish and maintain its latent state in the TG is not well understood. The purpose of this work was to better understand how neuropeptide signaling through neurokinin receptors, as well as how satellite glial cells (SGCs) …

Navigating Human Cytomegalovirus (Hcmv) Envelopment And Egress, William Longeway Close
Wayne State University Dissertations
Human cytomegalovirus (HCMV) is a ubiquitous viral pathogen. In individuals with fully functioning and mature immune systems, HCMV is associated with mild symptoms prior to establishing latency. In individuals with naïve or compromised immune systems, HCMV is capable of causing severe organ damage. HCMV is the leading infectious cause of congenital birth defects and a major non-genetic cause of hearing loss. Unfortunately, antiviral treatment options lack diversity due to limited knowledge of virion replication. If HCMV replication were better understood, new antiviral treatments could be developed.
In this work, we describe the development and implementation of new tools to study …

Biochemical, Structural, And Drug Design Studies Of Norovirus And Zika Virus Proteases, Ben Kuiper
Wayne State University Dissertations
Noroviruses, which are the leading cause of acute gastroenteritis, cause an estimated 677 million infections and 213,000 deaths each year worldwide. Noroviruses are classified into seven genogroups (GI-GVII); GI, GII, and GIV have been shown to be infectious in humans. However, GII noroviruses cause the majority of outbreaks (89%). No pharmacologic treatment or vaccine currently exists to treat or prevent norovirus infections.
Recently, the development of a norovirus replicon system, a murine model of norovirus infection, and the development of a biochemical protease assay have allowed for the design and development of norovirus inhibitors. However, the replicon and biochemical assay …

Human cytomegalovirus (HCMV) is a large double-stranded DNA virus that causes severe disease in newborns and immunocompromised patients. During infection, HCMV is able to reconfigure the host cell machinery to establish a virus producing factory, termed the cytoplasmic virion assembly complex (cVAC). Generating drugs that affect cVAC development or function provides an alternative mode of action for HCMV antivirals that can essentially eliminate virion production. The objective of …

Human Cytomegalovirus Us17 Locus Fine-Tunes Innate And Intrinsic Immune Responses, Stephen James Gurczynski
Wayne State University Dissertations
HCMV employs numerous strategies to combat, subvert, or co-opt host immunity. One evolutionary strategy for this involves "capture" of a host gene and then its successive duplication and divergence, forming a gene family, many of which have immunomodulatory activities. The HCMV US12 family consists of ten tandemly arranged sequence-related genes in the unique short region of the HCMV genome (US12-US21). Each gene encodes a protein possessing seven predicted transmembrane domains, and patches of sequence similarity with cellular GPCRs and the bax inhibitor-1 family of anti-apoptotic proteins. We show that one member, US17, plays an important role during virion maturation. Microarray …
Membrane-Bound Immunomodulators As Adjuvants In A Cell Culture-Based Avian Influenza Vaccine, David Daniel Fischer
Membrane-Bound Immunomodulators As Adjuvants In A Cell Culture-Based Avian Influenza Vaccine, David Daniel Fischer
Wayne State University Dissertations
Inactivated viral vaccines often generate suboptimal immune responses. Adjuvants are incorporated into vaccines to increase their immunogenicity, however currently available adjuvants have shortcomings which have limited their use in human and veterinary medicine. This necessitates the development of new adjuvants and delivery systems. Cytokines have been extensively tested as adjuvants in vaccines but challenges such as diffusion from antigen, short half-lives and production costs have been encountered. To address this, we developed a technology that efficiently produces inactivated, whole-virus influenza vaccine bearing membrane-bound cytokines. Tethering the cytokine to the antigen of interest keeps the immunomodulator in close contact with the …
