Department of Microbiology and Immunology Faculty Papers

Human onchocerciasis - commonly known as river blindness - is one of the most devastating yet neglected tropical diseases, leaving many millions in sub-Saharan Africa blind and/or with chronic disabilities. Attempts to eliminate onchocerciasis, primarily through the mass drug administration of ivermectin, remains challenging and has been heightened by the recent news that drug-resistant parasites are developing in some populations after years of drug treatment. Needed, and needed now, in the fight to eliminate onchocerciasis are new tools, such as preventive and therapeutic vaccines. This review summarizes the progress made to advance the onchocerciasis vaccine from the research laboratory into …

Regulation Of Prostaglandin D2 And Angiogenesis-Related Factors From Human Skin Mast Cells By Interleukin-6 And Resveratrol, Cody Cody Mchale

Theses and Dissertations

Mast cells are classically recognized as the effector cells of Immunoglobulin E (IgE)-mediated hypersensitivity reactions (i.e. allergic reactions). Mast cells also play an important role in the innate immune response to parasitic helminth infection. Allergic disease including allergic rhinitis, asthma, atopic dermatitis, and anaphylaxis, is a major health concern in the United States with greater than 60 million Americans suffering from allergy and asthma. In addition, mast cells have more recently been implicated in non-allergic disease including various human cancers, which will affect approximately 39.6% of U.S. men and women. Therefore, understanding the immunological and molecular mechanisms that regulate mast …

Parental Experience With Whole Exome Sequencing Reanalysis And Its Impact On The Diagnostic Odyssey, Nicole D. Lucas

Theses and Dissertations

Advances in genomic technology and an increase in the number of gene-disease associations have helped reduce the number of individuals living without a diagnosis. Whole exome sequencing (WES) analyzes the entire human exome in an attempt to determine if there is a molecular etiology for individuals who remain undiagnosed after other clinical or molecular investigations. Still, WES leaves most individuals undiagnosed, resulting in feelings of disappointment and uncertainty. Individuals who remain undiagnosed after WES can subsequently undergo WES reanalysis later due to improvements in bioinformatics, software updates, and an increase in known genedisease associations. This is the first study, to …

Differential Modulation Of Human Gabac‑Ρ1 Receptor By Sulfur‑Containing Compounds Structurally Related To Taurine, Lenin David Ochoa‑De La Paz, Martin González‑Andrade, Herminia Pasantes‑Morales, Rodrigo Franco, Rubén Zamora‑Alvarado, Edgar Zenteno, Hugo Quiroz‑Mercado, Roberto Gonzales‑Salinas, Rosario Gulias‑Cañizo

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: The amino acid taurine (2-Aminoethanesulfonic acid) modulates inhibitory neurotransmitter receptors. This study aimed to determine if the dual action of taurine on GABAC- ρ1R relates to its structure. To address this, we tested the ability of the structurally related compounds homotaurine, hypotaurine, and isethionic acid to modulate GABAC- ρ1R.

Results: In Xenopus laevis oocytes, hypotaurine and homotaurine partially activate heterologously expressed GABAC- ρ1R, showing an increment in its deactivation time with no changes in channel permeability, whereas isethionic acid showed no effect. Competitive assays suggest that hypotaurine and homotaurine compete for the GABA-binding site. In addition, their effects were …

Wnt Secretion Proteins Modulate Rankl-Induced Expression Of Aire In Thymic Epithelial Cells, Daniel Pollack

Dissertations and Theses

Thymic epithelial cells (TEC) are essential for a proper adaptive immune response by regulating thymocyte development and establishing central tolerance. In the thymus, TECs differentially express Wnt proteins, which activate canonical and non-canonical Wnt signaling pathways. Wnt signaling is thought to regulate cell survival, proliferation, and development although the direct molecular mechanisms in TECs have yet to be elucidated. The inducible inhibition of canonical Wnt signaling with Dkk1 leads to a rapid loss of TEC progenitors as well as a decline in mature Aire-expressing mTECs. Therefore, we explore the role of Wnt ligands potentially responsible for stimulating and/or regulating Wnt …

Neuromuscular Junction Defects In A Mouse Model Of Charcot-Marie-Tooth Disease Type 2o, Thywill Sabblah

Electronic Theses and Dissertations

Charcot Marie Tooth disease (CMT) represents the most common inheritable peripheral group of motor and sensory disorders; affecting 1 in 2500 people worldwide. Individuals with CMT experience slow progressing weakness of the muscle, atrophy, mild loss of motor coordination and in some cases loss of sensory function in the hands and feet which could ultimately affect mobility. Dynein is an essential molecular motor that functions to transport cargos in all cells. A point mutation in the dynein heavy chain was discovered to cause CMT disease in humans, specifically CMT type 2O. We generated a knock-in mouse model bearing the same …

Role Of Mycobacterium Avium Paratuberculosis (Map) And Tnfsf15 Snps On Tl1a In Cd, Sayf Al-Deen Hassouneh

Electronic Theses and Dissertations

Tumor Necrosis Factor-Like Ligand 1a (TL1A) is a cytokine encoded by Tumor Necrosis Factor Super Family 15 gene (TNFSF15) gene mostly in endothelial cells which binds to T-cells and foments the production of pro-inflammatory cytokines including TNF-α, IL-6, IL-1b, IFN- γ and IL-13. TL1A level is elevated in inflammatory diseases including Crohn's Disease (CD). Although Single Nucleotide Polymorphisms (SNPs) in TNFSF15 have been reported in CD, no studies have investigated the effect of these SNPs on TL1A, inflammation, and susceptibility to Mycobacterium avium subspecies paratuberculosis (MAP) infection. MAP is a strong candidate in CD pathogenesis. This study is designed to …

Exacerbation Of Δefp Sickness In Escherichia Coli By An Uncharacterized Rna Helicase, Robert Wingo

Electronic Theses and Dissertations

In Escherichia coli, growth is rate-limited by translation capacity [1]. Stalled ribosomes have profound effects on a cell such as altered mRNA abundance, decreased ribosome availability, and an imbalanced proteome. The absence of elongation factor P (EF-P), a universally conserved transpeptidation enhancer, presents an extreme example of this scenario, wherein ribosomes accumulate disproportionately onto messages that are more slowly translated and cell growth becomes notably impaired. We discovered that faster-growing cells arise spontaneously in Δefp cultures, suggesting that translation defects could be circumvented by mutating other genes. This thesis presents a genetic and biochemical analysis of a mechanism Δefp cells …

Assessing The Barriers To Cardiac Care In Carriers Of Duchenne And Becker Muscular Dystrophy, Lauren Renae Eekhoff

Theses and Dissertations

Duchenne and Becker muscular dystrophy (DBMD) are X-linked conditions due to mutations within the dystrophin gene that cause progressive muscle weakness, respiratory insufficiency, and cardiomyopathy in affected males. Approximately twothirds of women who have a son with DBMD are carriers of the condition. Carriers typically do not manifest muscular symptoms but are at risk for cardiac abnormalities such as dilated cardiomyopathies. The American Academy of Pediatrics (AAP) recommends that carriers of DBMD receive a complete cardiac evaluation by a cardiologist that includes an echocardiogram and electrocardiogram (EKG) with reevaluation every five years. According to a recent study33, as many as …

The Impact Of Communication Deficits On Puberty And Sexual Development In Adolescents On The Autism Spectrum, Ashton Wolfe

Theses and Dissertations

Transitioning into a sexually mature adult is a challenging time for both an adolescent with autism spectrum disorder (ASD) and his or her family. Sexual development begets challenges due to the demands it places on the social and communication skills needed to explore developmental changes that are occurring physically, emotionally and hormonally. A diagnosis of ASD is largely established by quantifying impediments in social and communication skills through observation. With deficits in these skills, one can assume that social and communication difficulties can create obstacles in the sexual development of affected individuals. Our study used quantitative and qualitative measures to …

Is Current Fragile X Syndrome Counseling Enough? Expanding The Clinical Phenotype Of Fragile X In Premutation And Intermediate Allele Carriers, Zahra Saadat Girnary

Theses and Dissertations

Fragile X syndrome (FXS) is caused by a triplet repeat expansion on the FMR1 gene. Individuals with >200 repeats have FXS, while individuals between 45-54 and 55- 200 repeats have the FMR1 intermediate allele and premutation, respectively. FXS is characterized by autism and intellectual disability while the premutation is associated with fragile X-associated tremor/ataxia syndrome (FXTAS) and fragile X-associated primary ovarian insufficiency (FXPOI). However, recent research shows that the premutation may be associated with psychiatric manifestations. Currently, there are no established clinical features associated with the intermediate allele. This study sought to 1) study knowledge regarding FXTAS, FXPOI, as well …

Role Of Mir-489 In Her2 Positive Breast Cancer, Yogin Patel

Theses and Dissertations

Human epidermal growth factor receptor 2 (HER2 or ErBb2) is a receptor tyrosine kinase overexpressed in 20-30% of breast cancers and associated with poor prognosis and outcome. Dysregulation of several micro RNAs (miRs) plays a key role in breast cancer progression and metastasis. In this study, we screened and identified miRs dysregulated in HER2-positive breast cancer cells. Molecular study demonstrated that miR-489 was specifically downregulated by the HER2-downstream signaling, especially the MAPK pathway. Restoration or overexpression of miR-489 in HER2-positive breast cancer cells significantly inhibited cell growth in vitro and decreased the tumorigenicity and tumor growth in xenograft mice. Mechanistically, …

Effect Of Resveratrol On The Development Of Eczema, Christopher Carlucci

Theses and Dissertations

Atopic dermatitis is a type of eczema characterized by chronic inflammation of the skin, affecting millions of people worldwide. Resveratrol, a naturally occurring stilbenoid, is widely believed to exhibit beneficial effects on a host of chronic diseases. Although some previous studies have aimed to evaluate the effects of resveratrol on the pathogenesis of atopic dermatitis, this relationship remains ill-defined. We have previously established that mast cell activation, remodeling, and cellular infiltration in the hypodermis all begin prior to the IgE-mediated immune response in an atopic dermatitis mouse model, and that this early pathogenesis is directly related to an increase in …

Integrating Genetic Counseling And Testing In The Pediatric Oncology Setting: Parental Attitudes And Influencing Factors, Lauren Renee Desrosiers

Theses and Dissertations

Cancer predisposition syndromes (CPS), caused by germline pathogenic variants in tumor suppressor genes and oncogenes, are genetic conditions that put an individual at increased risk to develop cancer. It is estimated that 10-15% of children with cancer have an underlying CPS. Although genetic testing for these conditions has become routine in the adult setting, incorporation of germline genomic technologies into pediatric cancer care has not occurred as rapidly. The purpose of this study is to assess desire for genetic counseling and testing services among parents of children with cancer to provide parental insight in the incorporation of genomic technologies in …

Role Of Cox2 In Cellular Senescence, Mingxiao Feng

Theses and Dissertations

The survivors of childhood cancers are often associated with adverse late effects including hypoplasia, fatigue, and infertility, which are characteristics of aging. However, the underlying mechanisms of the late effects of chemotherapy are still elusive. We have found that transgenic cyclooxygenase-2 (COX2) expression causes premature aging phenotypes. Since COX2 expression is highly induced by various chemotherapeutic agents, we further investigated the possible link between COX2 and the late effects of chemotherapy. Treatment of juvenile wild-type mice with doxorubicin (DOX), an anthracycline-based chemotherapeutic agent, resulted in premature aging phenotypes and escalated cellular senescence level in various tissues. We found that tissue …

Spiritual Care In Cancer Genetic Counseling: Patient Perceptions Of Methods, Christopher Michael Spencer

Theses and Dissertations

The integration of spirituality into medical care is a growing area of debate among professionals, involving a delicate balance between serving patients who may benefit from this without alienating those who would not. To date, little research has targeted spirituality in cancer genetic counseling, particularly concerning the various methods a genetic counselor can use to address spirituality with their patients. A paper questionnaire was created and distributed to patients following their cancer genetic counseling appointments to gain insight on their perception of these methods. Fifty-two participants completed this questionnaire. The eight different spiritual integration methods presented each showed positive responses …
