Brindley, Carlos Lopes, Jean Naples, Clive Shiff, Jorge Dupret, Lucio Lara Santos

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background. Schistosomiasis is a chronic disease caused by infection with parasitic worms of the genus Schistosoma. In sub-Saharan Africa, infections with S. haematobium are most common. Cystoscopic examination (CE) has been accepted as the gold-standard test for detecting the late manifestations of schistosomiasis, including urothelial cancer of the bladder. However, this procedure is invasive and 10 - 40% of tumours may remain undetected. A non-invasive examination and a new generation of biomarkers are needed for better monitoring of the disease.

Objective. To assess the usefulness of ultrasound (US) scans for monitoring of structural urinary tract disease by local public health …

Early Initiation Of Antiretroviral Therapy Can Functionally Control Productive Hiv-1 Infection In Humanized-Blt Mice, Qingsheng Li, For Yue Tso, Guobin Kang, Wuxun Lu, Yue Li, Wenjin Fan, Zhe Yuan, Christopher J. Destache, Charles Wood

Nebraska Center for Virology: Faculty Publications

Background—Recent reports showed that functional control of HIV-1 infection for a prolonged time is possible by early anti-retroviral therapy (ART); however its underlying mechanism needs to be studied with a suitable animal model. Recently, humanized-BLT (bone marrow, liver and thymus) mouse (hu-BLT) was shown to be an excellent model for studying HIV-1 infection. We thus tested the feasibility of studying functional control of HIV-1 infection using hu-BLT mice.

Methods—Animals in three treatment groups (Rx-6h, Rx-24h, Rx-48h) and untreated group were infected with HIV-1, followed by ART initiation at 6, 24 or 48 hours post-infection and continued daily for two weeks. …

The Role Of Dendritic Cell Subsets And Innate Immunity In The Pathogenesis Of Type 1 Diabetes And Other Autoimmune Diseases, Jeffrey D. Price, Kristin V. Tarbell

Nebraska Center for Virology: Faculty Publications

Dendritic cells (DCs) are key antigen-presenting cells that have an important role in autoimmune pathogenesis. DCs control both steady-state T cell tolerance and activation of pathogenic responses. The balance between these two outcomes depends on several factors, including genetic susceptibility, environmental signals that stimulate varied innate responses, and which DC subset is presenting antigen. Although the specific DC phenotype can diverge depending on the tissue location and context, there are four main subsets identified in both mouse and human: conventional cDC1 and cDC2, plasmacytoid DCs, and monocyte-derived DCs. In this review, we will discuss the role of these subsets in …

Hiv Genotyping Cost Analysis With Follow-Up As An Indicator, Laura Biederman, Md, Amity L. Roberts, Phd, D(Abmm)

Department of Pathology, Anatomy, and Cell Biology Resident's Posters

HIV-1 genotype (GHIV), HIV-1 Integrase (HIV1I) and HIV-1 Trophile (HIV1T) assays are sendout tests that incur a significant financial burden on the laboratory when ordered on inpatients who do not receive follow-up clinic visits. For these assays to be utilized in guiding antiretroviral therapy, the patient must receive follow-up. It will reduce the sendout budget by restricting these tests to the outpatient clinic setting.

A Nuclear Fraction Of Turnip Crinkle Virus Capsid Protein Is Important For Elicitation Of The Host Resistance Response, Sung-Hwan Kang, Feng Qu, Thomas J. Morris

Nebraska Center for Virology: Faculty Publications

The N-terminal 25 amino acids (AAs) of turnip crinkle virus (TCV) capsid protein (CP) are recognized by the resistance protein HRT to trigger a hypersensitive response (HR) and systemic resistance to TCV infection. This same region of TCV CP also contains a motif that interacts with the transcription factor TIP, as well as a nuclear localization signal (NLS). However, it is not yet known whether nuclear localization of TCV CP is needed for the induction of HRT-mediated HR and resistance. Here we present new evidence suggesting a tight correlation between nuclear inclusions formed by CP and the manifestation of HR. …

A Novel Codon-Optimized Siv Gag-Pol Immunogen For Genebased Vaccination, Catherine M. Crosby, Eric A. Weaver, Reeti Khare, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

Simian immunodeficiency virus (SIV) is a robust pathogen used in non-human primates to model HIV vaccines. SIV encodes a number of potential vaccine targets. By far the largest and most conserved protein target in SIV is its gag-pol protein that bears many epitopes to drive multivalent immune T cell responses. While gag-pol is an attractive antigen, it is only translated after a frame shift between gag and pol with the effect that gag and pol are expressed at an approximate 10/1 ratio. The codon bias of native lentiviral genes are also mismatched with the abundance of tRNAs in mammalian cells …

The Implications Of Hiv Treatment On The Hiv-Malaria Coinfection Dynamics: A Modeling Perspective, F. Nyabadza, B. T. Bekele, Megan A. Rúa, D. M. Malonza, N. Chiduku, M. Kgosimore

Biological Sciences Faculty Publications

Most hosts harbor multiple pathogens at the same time in disease epidemiology. Multiple pathogens have the potential for interaction resulting in negative impacts on host fitness or alterations in pathogen transmission dynamics. In this paper we develop a mathematical model describing the dynamics of HIV-malaria coinfection. Additionally, we extended our model to examine the role treatment (of malaria and HIV) plays in altering populations’ dynamics. Our model consists of 13 interlinked equations which allow us to explore multiple aspects of HIV-malaria transmission and treatment. We perform qualitative analysis of the model that includes positivity and boundedness of solutions. Furthermore, we …

High-Throughput Data Analysis: Application To Micronuclei Frequency And T-Cell Receptor Sequencing, Mateusz Makowski

Theses and Dissertations

The advent of high-throughput sequencing has brought about the creation of an unprecedented amount of research data. Analytical methodology has not been able to keep pace with the plethora of data being produced. Two assays, ImmunoSEQ and the cytokinesisblock micronucleus (CBMN), that both produce count data and have few methods available to analyze them are considered.

ImmunoSEQ is a sequencing assay that measures the beta T-cell receptor (TCR) repertoire. The ImmunoSEQ assay was used to describe the TCR repertoires of patients that have undergone hematopoietic stem cell transplantation (HSCT). Several different methods for spectratype analysis were extended to the TCR …

The I507-Atc→Att Silent Codon Change Contributes To The Misfolding Of ∆F508 Cftr, Vedrana Bali

All ETDs from UAB

Synonymous codon changes (SCCs) do not alter the amino acid sequence of proteins, but may significantly change the phenotype. The frequency of synonymous codons is species- and gene-specific, described as codon usage bias (CUB). Over the past 50 years, research has shown that SCCs affect protein biogenesis, development of human disorders and the function of recombinant proteins developed for therapeutic applications. However, the molecular mechanisms by which SCCs alter the function of gene products are not completely understood. In Chapter 2 we summarize present knowledge in this field. The most common cause of cystic fibrosis (CF) is the deletion of …

Intestinal Microbiota And Its Role In Mucosal And Systemic Immune Responses, Qing Zhao

All ETDs from UAB

Host-microbiota mutualism is established with long-term co-evolution. The abundant and diverse microbes colonizing on the surface of the host’s body, especially those in the gastrointestinal (GI) tract, play an essential role in the development and maturation of the host’s immune system. Failure of intestinal microbial control may lead to the development of an array of autoimmune diseases, including inflammatory bowel disease (IBD). As a well-recognized inflammation mediator, Th17 cells are actually among the most abundant effector CD4+ T cells in the normal adult gut. What the role of intestinal Th17 cells is under steady state conditions and how the intestinal …
