Fibrosis, driven by inflammation, marks the transition from benign to progressive stages of chronic liver diseases. Although inflammation promotes fibrogenesis, it is not known whether other events, such as hepatocyte death, are required for the development of fibrosis. Interferon Regulatory Factor 3 (IRF3) regulates hepatocyte apoptosis and production of Type-I interferons (IFNs). In the liver, IRF3 is activated via Toll-like receptor 4 (TLR4) signaling or the ER adapter, Stimulator of Interferon Genes (STING). We hypothesized that IRF3-mediated hepatocyte death is an independent determinant of chemically-induced liver fibrogenesis. To test this, we performed acute or chronic carbontetrachloride (CCl4) administration to WT, …

Inflammatory Gene Expression In Women Diagnosed With Polycystic Ovarian Syndrome, Myles K. Taylor
Inflammatory Gene Expression In Women Diagnosed With Polycystic Ovarian Syndrome, Myles K. Taylor
Electronic Theses & Dissertations
Polycystic ovarian syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The pathophysiology of PCOS has conventionally thought to originate from androgen excess. However, recent evidence suggests that androgen excess is a downstream consequence to inflammatory dysregulation and subsequent metabolic abnormalities. Inflammatory mRNA gene expression of TNFa and IL-1ß in mononuclear cells isolated from women diagnosed with PCOS was explored using qPCR. Additionally, the correlations between body mass index (BMI) and fasting glucose on mRNA expression of TNFa and IL-1ß were explored. mRNA expression of both TNFa and IL-1ß were found to be significantly higher in PCOS …
Molecular And Functional Analysis Of The Pixb Gene In Xenorhabdus Nematophila, John Lucas
Molecular And Functional Analysis Of The Pixb Gene In Xenorhabdus Nematophila, John Lucas
Theses and Dissertations
Xenorhabdus nematophila and the entomopathogenic nematode Steinernema carpocapsae form a mutualistic relationship facilitating the infection, death and consumption of an insect host. The infective juvenile (IJ) form of S. carpocapsae invades the insect host through natural openings and proceeds to the hemocoel where exposure to hemolymph stimulates the release of X. nematophila from the anterior vesicle. Excreted X. nematophila releases immunosuppressive compounds and insect toxins into the insect hemolymph that facilitates death of the host. As X. nematophila reaches high cell density it secretes exoenzymes that degrade insect tissues and produces antibiotics that reduce microbial competition. S. carpocapsae utilizes the …

The Effects Of Phytohormones And Isoprenoids In Dihydroartemisinin-Induced Dormancy In The Erythrocytic Stages Of Plasmodium Falciparum, Marvin Duvalsaint Duvalsaint
USF Tampa Graduate Theses and Dissertations
Our ability to control malaria has been challenged by increasing antimalarial resistance. Plasmodium falciparum undergoes dormancy in the blood stages which is hypothesized to be a means by which they are able to survive under drug pressure. This helps select for resistant parasites which grow following removal of drug. The mechanisms behind dormancy and the subsequent recrudescence are not fully understood but translating knowledge from related organisms which undergo a similar phenomenon might shed some light. Higher plants utilize dormancy during the early development stages to survive under unfavorable conditions, increasing fitness of the seedling and ensuring viability when this …
Mitochondrial Heteroplasmy Contributes To The Dynamic Atovaquone Resistance Response In Plasmodium Falciparum, Sasha Victoria Siegel
Mitochondrial Heteroplasmy Contributes To The Dynamic Atovaquone Resistance Response In Plasmodium Falciparum, Sasha Victoria Siegel
USF Tampa Graduate Theses and Dissertations
Of the considerable challenges researchers face in the control and elimination of malaria, the development of antimalarial drug resistance in parasite populations remains a significant hurdle to progress worldwide. Atovaquone is used in combination with proguanil (Malarone) as an antimalarial treatment in uncomplicated malaria, but is rendered ineffective by the rapid development of atovaquone resistance during treatment. Previous studies have established that de novo mutant parasites confer resistance to atovaquone with a substitution in amino acid 268 in the cytochrome b gene encoded by the parasite mitochondrial genome, yet much is still unknown about how this resistance develops, and whether …

The Rodent Parvovirus H-1 And Its Potential In Combination With Tien Hsien Liquid As A Treatment For Breast Cancer, Hayley I. Spires
Selected Honors Theses
Breast cancer is responsible for 12% of cancer diagnoses each year, and it is the leading cause of cancer-related mortality in women worldwide. Current treatments have provided some success in combatting the disease but are not considered a final solution. The framework for how researchers approach cancer has continued to change, and this includes the introduction of oncolytic viruses as novel therapeutics for cancer. The rodent parvovirus H-1 has shown strong potential in clinical and subclinical trials, but its S phase dependency limits its usefulness against cancer stem cell populations. Tien Hsien Liquid is commerically available, nontoxic, and has shown …
Dynamic Host-Pathogen Interactions Result In Fungal Epitope Unmasking, Alex Hopke
Dynamic Host-Pathogen Interactions Result In Fungal Epitope Unmasking, Alex Hopke
Electronic Theses and Dissertations
Molecular camouflage is used by a diverse set of pathogens to disguise their identity and avoid recognition by protective host receptors. The opportunistic fungal pathogen Candida albicans is a good example, as it masks the inflammatory component β-glucan in its cell wall to evade detection by the immune receptor Dectin-1. Interestingly, it has been seen that β-glucan becomes unmasked during infection in vivo, though the underlying mechanisms remained unclear. Exposure levels of this epitope may be important, as Dectin-1 mediates protection from some strains of C. albicans and alterations in the organization and composition of the Candida cell wall …

The murine monoclonal antibody LA-2 recognizes a clinically protective epitope on outer surface protein (OspA) of Borrelia burgdorferi, the causative agent of Lyme disease in North America. Human antibody equivalence to LA-2 is the best serologic correlate of protective antibody responses following OspA vaccination. Understanding the structural and functional basis of the LA-2 protective epitope is important for developing OspA-based vaccines and discovering prophylactic antibodies against Lyme disease. Here, we present a detailed structure-based analysis of the LA-2/OspA interaction interface and identification of residues mediating antibody recognition. Mutations were introduced into both OspA and LA-2 based on computational predictions on …
Innate Immunity In Chickens: In Vivo Responses To Different Pathogen Associated Molecular Patterns, Kristen Alicia Byrne
Innate Immunity In Chickens: In Vivo Responses To Different Pathogen Associated Molecular Patterns, Kristen Alicia Byrne
Graduate Theses and Dissertations
Pattern recognition receptors (PRRs) on host cells recognize motifs known as pathogen associated molecular patterns (PAMPs) that are common to groups of microbes. Examples include LPS on Gram-negative bacteria, the structural motif PGN common to all bacteria, MDP the smallest immunostimulatory unit of PGN, and poly I:C the dsRNA analog. PAMP recognition by and stimulation of the innate immune system is crucial to an individual’s ability to quickly limit microbial growth and stimulate the adaptive immune system. Characterization of the in vivo immune responses initiated by PAMPs has not been directly addressed. Using growing feathers (GF) as a novel intradermal …

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez
Biology: Student Scholarship & Creative Works
ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …
Characterization Of Induced Rnai Silencing Of Vaccinia Virus Essential Genes, Kewa Jiang
Characterization Of Induced Rnai Silencing Of Vaccinia Virus Essential Genes, Kewa Jiang
University Scholar Projects
Vaccinia virus (VACV) is a large double-stranded DNA virus and the prototypical member of the family Poxviridae and is most notable for its use as the vaccine that eradicated smallpox (variola virus). More recently, VACV has been used to develop recombinant vaccines and immunotherapies. However, many of these processes require VACV replication to be tightly controlled. RNA interference (RNAi) is a powerful tool for in vitro silencing of mRNAs that are complimentary to 19-21 base pairs (bp) of double-stranded RNA (dsRNA). This project outlines the design and preliminary analysis of two inducible RNAi silencing constructs targeting multiple VACV essential genes …

Optimization Of Expression And Purification Of The Rig-I-Like-Receptor, Lgp2, Srinath-Reddi Pingle
University Scholar Projects
The innate immune system is one of the first lines of defense against pathogens. RIG-I like receptors (RLRs) are a class of cytosolic receptors that recognize molecular patterns of invading pathogens and signal for downstream interferon induction. The RLR family consists of three proteins, RIG-I, MDA5, and LGP2. MDA5 and LGP2 work together to recognize and bind long viral dsRNA. LGP2 is thought to regulate MDA5 activation, but little is understood about this process. Characterization of the mechanism of action of these receptors requires careful biophysical and biochemical analyses. I have developed expression and purification of methods LGP2 and MDA5 …

Immune Modulating Functions By Soypeptide Lunasin In Cancer Immunotherapy, Chun-Yu Tung
Open Access Dissertations
Chemotherapy is currently the mainstay of treatment for most cancer patients. Despite its efficacy in eliminating cancer cells, a high percentage of chemotherapy patients eventually relapse or suffer progression of the disease. Immunosurveillance is capable of recognizing and eliminating continuously arising transformed mutant cells, and thus cancer immunotherapy is one of the emerging therapeutic strategies that harnesses the power of the immune system to eradicate chemotherapy-resistant cancerous cells. However, the adverse side effects of chemotherapy impede the therapeutic effects of immunotherapy. Our previous studies demonstrate that lymphoma patients are refractory to clinical immunotherapy because of chemotherapy-induced immune dysfunction. In addition, …

The use of antibiotics in poultry growth and disease control has led to antibiotics resistant problem in human beings, which is a big concern among consumers. With the necessity for judicious use of antibiotics in poultry production, alternative strategies to improve disease resistance in poultry production are necessary. The research is more inclined towards using the natural products available to grow healthier and antibiotic free meat animals. In the context of exploring natural and sustainable resource of alternative to antibiotics, the biochemical milieu of eggshell membranes (ESM) were analyzed by using mass spectrometry techniques including matrix assisted laser desorption ionization …
Preeclampsia: The Roles Of Acute Inflammation And Intrauterine Stress, Nicholas Parchim
Preeclampsia: The Roles Of Acute Inflammation And Intrauterine Stress, Nicholas Parchim
Dissertations & Theses (Open Access)
Preeclampsia (PE) is a severe, acute disease of pregnancy affecting approximately 8% of pregnant women after week 20 of gestation. PE is characterized by hypertension and renal damage reflected by proteinuria and has significant morbidity to both mother and fetus. Maternal symptoms range from headaches, nausea, edema, to visual changes, but once maternal symptoms present, damage to the fetus has begun. Mothers who progress untreated through the disease can also experience a condition called eclampsia characterized by seizure, coma, and, ultimately, death. PE-affected newborns experience features similar to prematurity—abnormal lung and renal development, intrauterine growth retardation (IUGR), and, possibly, fetal …
Doxycycline Resistance In Plasmodium Falciparum Linked To Single Nucleotide Polymorphisms In The Plasmodium Falciparum Apicoplast Small Subunit Ribosomal Rna (Pfssrrna) Gene, Amanda Wasko
Scholarly and Creative Works Conference (2015 - 2021)
Plasmodium falciparum, a protozoan parasite known as malaria, widely impacts human health; thus antimalarial drug investigations are critical. Doxycycline is a commonly used antimalarial prophylactic, but its mechanism of action is unclear. In prokaryotes, doxycycline works as an antibacterial by disrupting protein translation via the small subunit ribosome. Interestingly, P. falciparum has a small subunit ribosome of prokaryotic origins in the apicoplast, a plastid-like organelle. Therefore, we hypothesized that doxycycline works in P. falciparum by inhibiting protein synthesis via the small subunit ribosomal RNA and that mutations in the gene encoding the P. falciparum apicoplast small subunit ribosomal RNA …

TLR2 promotes NLRP3 inflammasome activation via an early MyD88-IRAK1-dependent pathway that provides a priming signal (signal 1) necessary for activation of the inflammasome by a second potassium-depleting signal (signal 2). Here we show that TLR3 binding to dsRNA promotes post-translational inflammasome activation through intermediate and late TRIF/RIPK1/FADD-dependent pathways. Both pathways require the scaffolding but not the catalytic function of caspase-8 or RIPK1. Only the late pathway requires kinase competent RIPK3 and MLKL function. Mechanistically, FADD/caspase-8 scaffolding function provides a post-translational signal 1 in the intermediate pathway, whereas in the late pathway it helps the oligomerization of RIPK3, which together with …

PURPOSE: Patient-reported outcome (PRO) measures are essential for assessing subjective patient experiences. Interactive voice response (IVR) data collection provides advantages for clinical trial design by standardizing and centralizing the assessment. Prior to adoption of IVR as a mode of PRO administration in the Testosterone Trials (TTrials), we compared IVR to paper versions of the instruments to be used. METHODS: IVR versions of the FACIT-Fatigue scale and Psychosexual Daily Questionnaire, Question 4, were developed. In one pilot study, IVR versions of these scales were compared to paper versions in 25 men = 65 years at each of two clinical sites. In …

BACKGROUND: Controversy continues regarding the appropriate assessment of fracture risk in long bone lesions affected by disseminated malignancy. QUESTIONS/PURPOSES: The purpose of this ongoing Musculoskeletal Tumor Society-sponsored, multi-institutional prospective cross-sectional clinical study is to compare CT-based structural rigidity analysis (CTRA) with physician-derived Mirels scoring for predicting pathologic fracture in femoral bone lesions. We hypothesized CTRA would be superior to Mirels in predicting fracture risk within the first year based on (1) sensitivity, specificity, positive predictive value, and negative predictive value; (2) receiver operator characteristic (ROC) analysis; and (3) fracture prediction after controlling for potential confounding variables such as age and …

Although timing deficits are a robust finding in schizophrenia (SZ), the notion of a genuine time perception disorder in SZ is still being debated because distortions in timing might depend on neuropsychological deficits that are characteristics of the illness. Here we used meta-analytic methods to summarize the evidence of timing deficits in SZ and moderator analyses to determine whether defective timing in SZ arises from nontemporal sources or from defective time perception. PubMed Services, PsycNET, and Scopus were searched through March 2015, and all references in articles were investigated to find other relevant studies. Studies were selected if they included …

Early Rescue Of Interneuron Disease Trajectory In Developmental Epilepsies., Ms Siehr, Jl Noebels
Faculty Publications
The discovery of over 150 monogenic epilepsies and advances in early genetic diagnoses have launched a search for molecular strategies and developmental timetables to reverse or even prevent the course of these debilitating brain disorders. Orthologous rodent models of key disease genes are providing important examples of the range of targets, and serve as valuable test systems for perinatal therapeutic approaches. While gene-specific analyses of single rare 'orphan' diseases are each narrow in scope, they illuminate downstream pathways converging onto interneurons, and treatments that strengthen inhibition during cortical maturation may provide broad protection against these seemingly disparate gene errors. Several …

The nervous system consists of neurons and glial cells. Neurons generate and propagate electrical and chemical signals, whereas glia function mainly to modulate neuron function and signaling. Just as there are many different kinds of neurons with different roles, there are also many types of glia that perform diverse functions. For example, glia make myelin; modulate synapse formation, function, and elimination; regulate blood flow and metabolism; and maintain ionic and water homeostasis to name only a few. Although proteomic approaches have been used extensively to understand neurons, the same cannot be said for glia. Importantly, like neurons, glial cells have …

The therapeutic benefits of the neuraminidase (NA) inhibitor oseltamivir are dampened by the emergence of drug resistance mutations in influenza A virus (IAV). To investigate the mechanistic features that underlie resistance, we developed an approach to quantify the effects of all possible single-nucleotide substitutions introduced into important regions of NA. We determined the experimental fitness effects of 450 nucleotide mutations encoding positions both surrounding the active site and at more distant sites in an N1 strain of IAV in the presence and absence of oseltamivir. NA mutations previously known to confer oseltamivir resistance in N1 strains, including H275Y and N295S, …

Functional Consequences Of Ama1-Ron2 Interaction During Host Cell Invasion By Toxoplasma., Shruthi Krishnamurthy
Graduate College Dissertations and Theses
T.gondii is a model organism of the phylum Apicomplexa that infects one third of the human population. While the majority of infections are asymptomatic or manifest with mild flu-like symptoms, toxoplasmosis can be fatal in immunocompromised individuals and in the developing fetus. The lytic cycle of tachyzoite-stage parasites causes damage to the host by repeated rounds of host cell invasion, intracellular replication and lysis of the host cell upon egress.
Invasion is a key step for the parasite to maintain its intracellular lifestyle. Apical Membrane Antigen 1 (AMA1) is an adhesin released from a unique set of secretory organelles called …
