Structure-Guided T Cell Receptor Mutations That Alter Antigen Specificity, Cross-Reactivity, And Polyfunctional Phenotypes In Gene-Modified T Cells, Kendra Foley

Dissertations

Adoptive cell transfer of T cell receptor (TCR) gene-modified T cells targeting specific tumor antigens is currently in clinical trials for patients with advanced malignancies. Despite the clinical responses, there are still hurdles to be overcome in achieving an effective and safe therapy. One of the limitations in the success of this type of therapy is the potential for cross-reactivity and unanticipated off-target reactivity which could lead to autoimmunity. Adverse events encompassing these "off-target, off-tumor" cross-reactivities leading to autoimmunity have been seen in patients in different clinical trials. Here, we demonstrate a novel approach to improve antigen specific reactivity and …

Determination Of Transforming Growth Factor-Β Signaling Targets In Activated T Cells, Ramiah Jacks

Dissertations

T lymphocytes are a critical component of the adaptive immune system and their responses in pathogenic and steady state conditions require strict regulation. One mechanism involved in this regulation is Transforming Growth Factor-β (TGF-β) signaling. TGF-β can act on activated T cells to facilitate the differentiation of TGF-β dependent T helper subsets or the suppression of T cell activation and proliferation. However, the molecular mechanism(s) by which TGF-β signaling controls T cell differentiation vs T cell suppression remain poorly understood.TGF-β signaling is propagated by initially binding to the TGF-β type II receptor, which subsequently activates TGF-β type I receptor (TGF-βRI) …

Aerococcus Urinae: Establishing The Pathogenesis Of An Emerging Uropathogen, Evann E. Hilt

Dissertations

Urinary tract infection (UTI) is the world's most common bacterial infection. Much is known about the infectious process (pathogenesis) of a few of the bacteria that cause these infections, especially E. coli. Unfortunately, the pathogenesis of E. coli and other uropathogenic bacteria was explored almost exclusively in the belief that the bladder is supposed to be sterile. Our recent evidence, however, debunks this dogma. We used modern methods to reveal diverse bacterial communities in the bladders of adult women. These communities differ in women with and without lower urinary tract symptoms (LUTS), including UTI and urinary incontinence (UI). Many bacteria …

Protection From Staphylococcus Aureus Bloodstream Infection By Probiotic Exopolysaccharide, Wonbeom Paik

Dissertations

Staphylococcus aureus is known to cause severe systemic infection with high mortality rates. Antibiotics are the only approved therapy for patients, but the widespread prevalence of antibiotic resistant strains limits treatment efficacy, and many patients succumb to the disease. Many probiotic agents are commercially available, but the mechanisms by which they benefit are not known. Understanding these mechanisms will help develop novel therapeutics that can improve healthcare, including systemic infections by S. aureus. Bacillus subtilis is a probiotic bacterium that produces an exopolysaccharide (EPS) that induces anti inflammatory macrophages (MΦ). We tested if EPS could be used for systemic S. …

Yczr, A New Case Of Plp-Dependent Mocr/Gabr Type Transcription Regulator In Klebsiella Pneumonia, Yuanzhang Zheng

Dissertations

Increasing number of genes encoding PLP-dependent transcription regulators, MocR/GabR type regulators, have been identified in various bacterial genomes. However, only a handful of them, including MocR, PdxR and GabR have been studied experimentally. They control different aspects of the bacterial metabolism. Only GabR has reported crystallographic structures. MocR/GabR regulators possess a chimeric structure consisted of a WHTH DNA binding domain and an Aminotransferase-like regulation domain, which can bind PLP as an effector in transcription regulation. Such a chimeric construct presents an interesting case in molecular evolution. The regulation domains of All MocR/GabR type regulators loss their catalytic capacity during evolution …

Menstrual Justice, Margaret E. Johnson

All Faculty Scholarship

Menstrual injustice is the oppression of menstruators, women, girls, transgender men and boys, and nonbinary persons, simply because they menstruate. Acts of menstrual injustice occur every day in the United States. The narrative of menstruation is that it is a taboo, shameful, and that menstruators are dirty, impure, even dangerous. Menstruation has been shunned generally from public discourse as a result. This narrative negatively impacts menstruators. Menstruators are essentialized as women, often of means, excluding transgender men and nonbinary persons, and menstruators who experience poverty or are young. Menstruating workers, especially low-wage workers, are harassed, penalized, or fired for heavy …

A Proteomics Approach To Investigate Uropathogenic Escherichia Coli, Nizar Hamed E Saeedi

Other Faculty of Health Theses

Uropathogenic Escherichia coli (UPEC) is the most commonly known cause of urinary tract infection (UTI). The possession of many virulence factors and global dissemination of multi-drug resistant UPEC strains is posing a critical risk to treatment worldwide. The most virulent UPEC strains have descended from major lineages such as sequence type (ST) 131, ST38 and ST127. Strains of ST127 exhibit the highest virulence potential of most UPEC lineages, but little is known about their pathogenicity. Previous studies have reported the important role of metabolic adaptations in UPEC virulence. This study investigated the metabolic adaptations of UPEC isolates, with a focus …

Medical Microbiology: Discovery Of New Antimicrobial Drugs To Treat Clinically Relevant Antibiotic Resistant Pathogenic Bacteria, Abdu Hussein A. Aldarhami

Other Faculty of Health Theses

Antimicrobial resistance (AMR) is one of the greatest world-wide threats to human health and urgent action is needed to reduce the potentially devastating social and economic impacts that may result from continued spread of drug resistant infections. These actions include discovery of new antibiotics and community engagement in AMR. Natural product screening methods are arguably the most efficient way to identify novel antibiotics, but can be frustrated by the repeated discovery of known compounds, wasting valuable resources, effort and time. Thus, exploiting obscure, hard to reach environments and implementing combined bioinformatic and proteomic screening approaches may short-cut the process of …
