Hypervirulent Clostridium Difficile Strains: Adherence, Toxin Production And Sporulation, Michelle Marie Merrigan

Dissertations

Clostridium difficile is a leading cause of nosocomial infections, and recently emerged "hypervirulent" C. difficile strains have caused epidemics worldwide. We hypothesized that multiple factors were responsible for this phenotype, particularly the interaction of C. difficile with the epithelial cell, as well as toxin production and sporulation.

To test if host interaction varied in HV strains, we developed a quantitative host-cell adherence assay, and found that while C. difficile strains varied in adherence to human intestinal epithelial cells, hypervirulent strains were not significantly more adherent than other strains. The bacterial surface protein SlpA varied in both size and amount between …

Forced-Exercise Alleviates Neuropathic Pain In Experimental Diabetes: Effects On Voltage-Gated Calcium Channels, Sahadev A. Shankarappa

Dissertations

Exercise is now established as an integral adjunct to the management of diabetes. Diabetic polyneuropathy, a painful complication of diabetes, remains untreatable, emphasizing a critical need for improved therapeutic strategies. Recent evidence suggests that exercise may facilitate recovery of peripheral nerve function in diabetes. However, the mechanism by which exercise protects against diabetes-induced nerve dysfunction is unknown. In this dissertation we hypothesized that forced-exercise protects against experimental DPN by preventing glucose-associated alterations of voltage-gated calcium currents (VGCC) in small diameter dorsal root ganglion (DRG) neurons. Using behavioral, nerve-electrophysiology and patch-clamp methodology we examined the functional consequences of forced-exercise (treadmill, 5.4 …

Notch Signaling Is Important In The Survival, Proliferation, And Self-Renewal Of The Putative Breast Cancer Stem Cell Population, Peter Grudzien

Dissertations

Numerous studies have identified stem-like cells, termed cancer stem cells (CSCs), in breast tumors and established cell lines. It has been hypothesized that CSCs are responsible for breast cancer formation, progression and recurrence; therefore, a deeper understanding of the signaling pathways regulating CSC survival will benefit development of novel therapeutic strategies. Notch signaling, which is dysregulated in breast cancer and has been implicated in mammary stem cell self-renewal, and can be effectively blocked by gamma-secretase inhibitors (GSIs). While GSIs are currently in clinical trials for breast cancer, it is not fully understood how these compounds will affect CSCs or if …

Coronavirus Replicase Proteins: Multifunctional Mediators Of Replication And Innate Immunity Evasion, Mark Anthony Clementz

Dissertations

Coronaviruses are positive-sense, single-stranded RNA viruses. The majority of the RNA encodes non-structural proteins (nsps) that are translated as a large polyprotein, which is cleaved by the papain-like (PLP) and picornavirus 3C-like (3CLpro) proteases. The nsps modify host membranes to produce double membrane vesicles (DMVs) upon which the replicase-transcriptase assembles and synthesizes viral RNA. nsp3, nsp4, and nsp6 are integral membrane proteins believed to be involved in DMV formation. Work presented here demonstrates that nsp4 is subjected to N-linked glycosylation and mutation of N258 to threonine in nsp4 confers a temperature sensitive phenotype to MHV-A59 infectious clone virus. This virus …
