Use Of Immunotherapy In The Treatment Of Peanut Allergies In The Pediatric Population, Bethany Rauscher

Senior Honors Theses

Peanut allergies are a serious issue that must be monitored and treated effectively to avoid severe adverse effects and death. In the last decade, their incidence has increased significantly, due to indeterminate factors. Because people typically do not outgrow peanut allergies and the effects of exposure can be life-threatening, it is important that a cure or management method is developed and refined. Recent research regarding treatment for peanut allergies has focused on the use of immunotherapy, a process aimed at desensitizing children's immune systems so that they do not reject foods that contain peanuts. Some studies utilizing immunotherapy have provided …

The Use Of Shape Memory Polymers As A Tool To Study Human Fibrosarcoma And Murine Mesenchymal Stem Cell Migration, Justin N. Elkhechen

Renée Crown University Honors Thesis Projects - All

Shape memory polymers (SMPs) are a class of “smart” materials that can transform between two distinct conformations through external stimuli, such as heat or electricity. Their usage in bioengineering has led to a promising field of research that lies at the interface of cell and mechanobiology, potentially providing insight into cancer therapies and tissue development—two processes that exist in dynamic environments in vivo. The present work involves creating new, shape changing, scaffolds for studies to analyze cell migration upon changes to the environmental topography. Specifically, this Capstone has been primarily focused on the development of a “half and half” fibrous …

Correlation Matrix Analysis Identifies Gene Signatures Of Immune Cell Subsets And Their Interactions In Follicular Lymphoma, Jason R. Westin

Dissertations and Theses (Open Access)

There are important but ill-defined interactions between benign immune cell subsets and neoplastic B cells within follicular lymphoma (FL). Using the novel technique of correlation matrix analysis (CMA) of publicly available FL whole-tumor gene expression profiling (GEP) data, we have identified signatures of immune cell subsets. Overall survival correlated most highly with a model using signatures of macrophages, T cells, and stroma, which was able to add significantly to existing clinical prognostic tools. From our own data of a cohort of 43 FL tumors sorted into B-cell and non-B cell (NB) fractions for GEP, CMA of the tumor infiltrating NB …

Human Stem Cells: Is It Possible To Limit Pluripotent Human Stem Cells To Differentiate Into Specific Tissue Or Organ?, Chaya Korf

The Science Journal of the Lander College of Arts and Sciences

It would seem that differentiation of stem cells is the remedy of modern times. Yet stem cell research is more complex that the public may recognize and is still in the developmental stage. Recent breakthroughs show promise; various guidelines provide structure to this growing field but it is not ready for gross public application. The objective of this paper is to research various different methods of stem cell production and application. Methods included reviewing articles and studies to evaluate the process in production of affective stem cells. There are many therapies that illustrate this research. Upon completing and explaining this …

Missing-In-Metastasis Regulates Cell Motility And Invasion Via Ptpdelta-Mediated Changes In Src Activity, F. Chaudhary, R. Lucito, N. K. Tonks

Journal Articles

MIM (Missing-in-Metastasis), also known as MTSS1 (metastasis suppressor 1), is a scaffold protein that is down-regulated in multiple metastatic cancer cell lines compared with non-metastatic counterparts. MIM regulates cytoskeletal dynamics and actin polymerization, and has been implicated in the control of cell motility and invasion. MIM has also been shown to bind to a receptor PTP (protein tyrosine phosphatase), PTPdelta, an interaction that may provide a link between tyrosine-phosphorylation-dependent signalling and metastasis. We used shRNA-mediated gene silencing to investigate the consequences of loss of MIM on the migration and invasion of the MCF10A mammary epithelial cell model of breast cancer. …

Epigenetic Role Of Ptip In Mouse Spermatogenesis, Chengjing Liu

Theses, Dissertations and Capstones

In mammals, spermatogenesis is a biological process inside the testis to produce spermatozoa from spermatogonia. This process is governed by both genetic and epigenetic mechanisms and thus is a powerful system for epigenetic research. Methylation of histone 3 lysine 4 (H3K4) is an epigenetic mark, which has been found to be dynamically modulated in mouse male germ cells during spermatogenesis. Pax2 Transactivation domain Interaction Protein (PTIP) has been recently identified as part of a H3K4 methyltransferase complex. In this study, I hypothesize that PTIP is an essential epigenetic regulator in mouse spermatogenesis. To test this hypothesis, I first established a …

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 …

Cerium Oxide Nanoparticles Attenuate Polymicrobial Sepsis Induced Splenic Damage In Male Sprague Dawley Rats, Venkata Vinay Kumar Bandarupalli

Theses, Dissertations and Capstones

Sepsis is a serious life threatening medical emergency which, if not treated properly, oftentimes results in organ failure and death. Current sepsis treatment protocols are largely centered on the use of antibiotics and supportive care. Recent studies have suggested that antibiotics fail to be effective for sepsis treatment when administered during hypo-dynamic phase of sepsis that is usually characterized by the presence of a cytokine storm. As such, there is an urgent need to develop novel therapeutic drugs that target the inflammatory cytokines that are secreted as a result of increased reactive oxygen species. Cerium oxide nanoparticles (CeO2) have been …

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 Use Of Rna Interference To Mitigate Pulmonary Fibrosis In Response To Asbestos Exposure, Sarah Kinsey

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The adverse health effects of exposure to asbestos are widely known and have been well documented. When a person is diagnosed with asbestosis, a chronic lung disease caused by inhaling asbestos fibers, few treatment options exist, none of which halt or reverse the progression of the disease. The rapidly growing field of gene therapy offers new avenues for potential treatments worthy of investigation. The detrimental effects of asbestos exposure are due to the physiological response of the lungs to asbestos fibers in the form of fibrosis, a result of excess extracellular collagen deposition. A protein called SPARC (Secreted Protein Acidic …

Whole-Genome Sequencing Of Kaposi’S Sarcoma-Associated Herpesvirus From Zambian Kaposi’S Sarcoma Biopsy Specimens Reveals Unique Viral Diversity, Landon Olp, Adrien Jeanniard, Clemence Marimo, Charles Wood

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent for Kaposi’s sarcoma (KS). Both KSHV and KS are endemic in sub-Saharan Africa where approximately 84% of global KS cases occur. Nevertheless, whole-genome sequencing of KSHV has only been completed using isolates from Western countries—where KS is not endemic. The lack of whole-genome KSHV sequence data from the most clinically important geographical region, sub-Saharan Africa, represents an important gap since it remains unclear whether genomic diversity has a role on KSHV pathogenesis. We hypothesized that distinct KSHV genotypes might be present in sub-Saharan Africa compared to Western countries. Using a KSHV-targeted enrichment …

Nebraska Center for Virology: Faculty Publications

The Liangshan prefecture in Sichuan province is an area in China severely affected by the HIV epidemic, with intravenous drug use (IDU) as the main risk factor. No reports on HIV subtypes prevalent in IDUs in Liangshan prefecture could be found. In this study, we have characterized the genotypes of HIV-1 in the IDU population in Liangshan prefecture and further determined the phylogenetic relationship of the CRF07_BC strains to HIV-1 sequences from the other regions of China, including Xinjiang and Yunnan provinces, to explore the pattern and possible diffusion pathway of HIV-1 in these regions. HIV-1-seropositive drug-naive IDUs identified in …

The onset of protective immunity against pathogenic SIV challenge in SIVΔnef-vaccinated macaques is delayed for 15-20 weeks, a process that is related to qualitative changes in CD8⁺ T cell responses induced by SIVΔnef. As a novel approach to characterize cell differentiation following vaccination, we used multi-target qPCR to measure transcription factor expression in naïve and memory subsets of CD8+⁺ T cells, and in SIV-specific CD8⁺ T cells obtained from SIVΔnef-vaccinated or wild type SIVmac239-infected macaques. Unsupervised clustering of expression profiles organized naïve and memory CD8⁺ T cells into groups concordant with cell surface phenotype. Transcription factor …

Escherichia Coli Surface Display Of Single-Chain Antibody Vrc01 Against Hiv-1 Infection, Lin-Xu Wang, Michael Mellon, Dane Bowder, Meghan Quinn, Danielle Shea, Charles Wood, Shi-Hua Xiang

Nebraska Center for Virology: Faculty Publications

Human immunodeficiency virus type 1 (HIV-1) transmission and infection occur mainly via the mucosal surfaces. The commensal bacteria residing in these surfaces can potentially be employed as a vehicle for delivering inhibitors to prevent HIV-1 infection. In this study, we have employed a bacteria-based strategy to display a broadly neutralizing antibody VRC01, which could potentially be used to prevent HIV-1 infection. The VRC01 antibody mimics CD4-binding to gp120 and has broadly neutralization activities against HIV-1. We have designed a construct that can express the fusion peptide of the scFv-VRC01 antibody together with the autotransporter β-barrel domain of IgAP gene from …

Evidence For Placental Hpv Infection In Both Hiv Positive And Negative Women, Chrispin Chisanga, Dawn Eggert, Charles D. Mitchell, Charles Wood, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Human papillomaviruses (HPVs) have previously been reported to infect epithelial trophoblast cells of the placenta. To investigate this possibility, 200 placental samples from Zambian women were separated into HIV+ and HIV− groups and tested for HPV by redundant primer PCR, using GP5+/GP6+ and CPI/CPII primer sets. Three HPV genotypes (HPV6, 16 and 90) were detected in placental samples. Whereas, 20 different HPV genotypes were detected in vaginal sampling of the same patients, suggesting that compartment specific sub-populations of HPV may exist. The incidence of HPV16 in placental samples was almost 2-fold greater in HIV+ women compared to HIV− (p = …

The Hippo/Yap Pathway Interacts With Egfr Signaling And Hpv Oncoproteins To Regulate Cervical Cancer Progression, Chunbo He, Dagan Mao, Guohua Hua, Xiangmin Lv, Xingcheng Chen, Peter C. Angeletti, Jixin Dong, Steven W. Remmenga, Kerry J. Rodabaugh, Jin Zhou, Paul F. Lambert, Peixin Yang, John S. Davis, Cheng Wang

Nebraska Center for Virology: Faculty Publications

The Hippo signaling pathway controls organ size and tumorigenesis

through a kinase cascade that inactivates Yes-associated

protein (YAP). Here, we show that YAP plays a central role in

controlling the progression of cervical cancer. Our results suggest

that YAP expression is associated with a poor prognosis for cervical

cancer. TGF-α and amphiregulin (AREG), via EGFR, inhibit the Hippo

signaling pathway and activate YAP to induce cervical cancer cell

proliferation and migration. Activated YAP allows for up-regulation

of TGF-α, AREG, and EGFR, forming a positive signaling loop to

drive cervical cancer cell proliferation. HPV E6 protein, a major

etiological molecule of …

Kaposi’S Sarcoma At The University Teaching Hospital, Lusaka, Zambia In The Antiretroviral Therapy Era, Owen Ngalamika, Veenu Minhas, Charles Wood

Nebraska Center for Virology: Faculty Publications

With great interest, we read the recent publication “Kaposi’s sarcoma in HIV-infected patients in South Africa: Multicohort study in the antiretroviral therapy era” by Bohlius et al. We congratulate the authors for their contribution to this field. In this study the authors observed a decrease in incidence of Kaposi’s sarcoma (KS) in patients treated with anti-retroviral therapy (ART) when compared to patients who are not on ART. These results are encouraging because of the ongoing HIV epidemic in sub-Saharan Africa where KS is still one of the most prevalent cancers. Also, it is a relevant topic to study in …

Activation And Degradation Of Open Reading Frame 45 By The Replication And Transcription Activator Of Kaposi's Sarcoma-Associated Herpesvirus, Ying Wang, Kai Yu, Xiuzhi Pei, Tiancheng Zhang, Yuying Guo, Charles Wood, Jinzhong Wang

Nebraska Center for Virology: Faculty Publications

The open reading frame 45 (ORF45) of the Kaposi's sarcoma-associated herpesvirus (KSHV) is an immediate-early phosphorylated tegument protein critical for viral escape from host immune surveillance. Its expression is upregulated by the viral replication and transcription activator (RTA), a key protein that controls the switch from latency to lytic replication. We report here that ORF45 expression was not only upregulated by RTA, but ORF45 could also be degraded by RTA in a proteasome-dependent manner. The ORF45 was activated by RTA via activation of the ORF45 promoter, and the promoter region from nt 69 271 to nt 69 026 was involved. …

Single-Dose Cpg Immunization Protects Against A Heterosubtypic Challenge And Generates Antigen-Specific Memory T Cells, Alexander J. Vogel, Deborah M. Brown

Nebraska Center for Virology: Faculty Publications

Despite extensive research, influenza A virus (IAV) remains a major cause of morbidity, mortality, and healthcare expenditure. Emerging pandemics from highly pathogenic IAV strains, such as H5N1 and pandemic H1N1, highlight the need for universal, crossprotective vaccines. Current vaccine formulations generate strain-specific neutralizing antibodies primarily against the outer coat proteins, hemagglutinin and neuraminidase. In contrast to these highly mutable proteins, internal proteins of IAV are more conserved and are a favorable target for developing vaccines that induce strong T cell responses in addition to humoral immunity. Here, we found that intranasal administration with a single dose of CpG and inactivated …

Long-Acting Parenteral Combination Antiretroviral Loaded Nano-Drug Delivery System To Treat Chronic Hiv-1 Infection: A Humanized Mouse Model Study, Subhra Mandal, Guobin Kang, Pavan Kumar Prathipati, Wenjin Fan, Qingsheng Li, Christopher J. Destache

Nebraska Center for Virology: Faculty Publications

Human immunodeficiency virus (HIV) patients are often diagnosed in the chronic stage of HIV/AIDS. Combination antiretroviral therapy (cART) has improved quality of life for HIV-infected patients. Present study describes a novel long-acting parenteral formulation of combination antiretroviral (cARV) loaded nano-drugs for treating chronic HIV-1 (cHIV) in a humanized-BLT (hu-BLT) mice model. The cARV (elvitegravir + tenofovir alafenamide + emtricitabine; EVG + TAF + FTC) drugs (mimicking marketed Genvoy® one-pill for HIV-treatment) were encapsulated in poly (lactic-co-glycolic acid) nanoparticles (NPs). To establish cHIV, hu-BLT mice were intravaginally challenged with HIV-1 and maintained for 15 weeks. Plasma viral load (pVL) was monitored …

Er-Associated Degradation And Cadmium Dependent Rescue Of Pca1, Nathan Smith

Department of Biochemistry: Dissertations, Theses, and Student Research

Protein synthesis and proper folding is an essential process for all organisms. In eukaryotes proteins of the secretory pathway are synthesized and inserted into the lumen or membrane of the endoplasmic reticulum. Eukaryotic cells maintain a mechanism for removal of proteins unable to fold properly. This process is known as ER-associated degradation (ERAD). A poorly functioning ERAD can lead to a build-up of misfolded proteins which has been implicated in several degenerative diseases such as Alzheimer’s, Amyotrophic lateral sclerosis, and Parkinson’s. Thus, the study of how proteins are recognized, extracted from the ER, and degraded is essential for determining methods …

Quantitative Assessment Of Blood Coagulation By Cold Atmospheric Plasma, Caitlin Heslin, Daniela Boehm, Vladimir Milosavljevic, Michelle Laycock, Patrick J. Cullen, Paula Bourke

Articles

Cold atmospheric plasma (CAP) is produced by ionizing a chosen gas, thereby creating charged and reactive species. The reactive species generated are capable of inducing a range of biomedically relevant interactions including blood coagulation. However, the underlying biochemical processes of plasma-assisted blood coagulation are largely unknown, and data quantifying blood clot formation or the impact of system parameters on the intensity of the blood clot are scarce. In this study, blood coagulation was quantified by measuring hemoglobin absorbance. System parameters of the kINPen plasma jet were investigated and compared, including treatment time, distance from the plasma source and gas flow …

Imaging Luciferase-Expressing Viruses, Michael A. Barry, Shannon May, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Optical imaging of luciferage gene expression has become a powerful tool to track cells and viruses in vivo in small animal models. Luciferase imaging has been used to study the location of infection by replication-defective and replication-competent viruses and to track changes in the distribution of viruses in mouse models. This approach has also been used in oncolytic studies as a non-invasive means to monitor the growth and killing of tumor cells modified with luciferase genes. In this chapter, we describe the techniques used for luciferase imaging as have been applied to track replication-defective and replication-competent adenoviruses in mouse and …

The Mucosal Expression Pattern Of Interferon-Ε In Rhesus Macaques, Andrew Demers, Guobin Kang, Fangrui Ma, Wuxun Lu, Zhe Yuan, Yue Li, Mark Lewis, Edmundo N. Kraiselburd, Luis Montaner, Qingsheng Li

Qingsheng Li Publications

Type I IFNs play an important role in innate and adaptive immunity against viral infections. A novel type I IFN, namely IFN-ε, which can protect against vaginal transmission of HSV2 and Chlamydia muridarum bacterial infection, has been described in mice and humans. Nevertheless, the principle cell type and the expression pattern of IFN-ε in tissues remain uncertain. In addition, the expression of IFN-ε in Indian rhesus macaques (Macaca mulatta) has not been reported. Here, we analyzed IFN-ε expression in multiple mucosal sites of uninfected or SIV-infected Indian rhesus macaques using IHCS. We report for the first time the …

The Role Of Traf6 Phosphorylation In Src/Traf6-Mediated Ikk, Jnk, Akt Activation And Tumorigenesis, Yun Seong Jeong

Dissertations and Theses (Open Access)

TRAF6 E3 ligase regulates numerous essential biological processes such as innate immune response, cell survival and osteoclast differentiation. Upon activation, it mediates activation of IKK/NF-κB and JNK signaling in response to engagement of toll-like receptor 4 (TLR4), interleukin-1 receptor (IL-1R), and receptor activator of NF-κB (RANK) to their cognate ligands, including lipopolysaccharide (LPS), IL-1, and RANK ligand (RANKL). Recently, TRAF6 has also been shown to be involved in Akt signaling activation upon activation of insulin-like growth factor-1 receptor (IGF-1R), in turn orchestrating cell survival and tumorigenesis. Therefore, TRAF6 is a key player for the activation of IKK, JNK and Akt …

Fty720 (Fingolimod) Provides Insight Into The Molecular Mechanisms Of Multiple Sclerosis, Madelyn Elizabeth Crawford

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Multiple sclerosis (MS) is a neurodegenerative disorder caused by a prolonged immune- mediated inflammatory response that targets myelin. Nearly all of the drugs approved for the treatment of MS are general immunosuppressants or only function in symptom management. The oral medication fingolimod, however, is reported to have direct therapeutic effects on cells of the central nervous system in addition to immunomodulatory functions. Fingolimod is known to interact with sphingosine-1-phosphate (S1P) receptors, and the most widely- accepted theory for its mechanism of action is functional antagonism of the receptor. This review examines significant neuromodulatory effects achieved by functional antagonism of the …

Cytokine Control Of Glioma Adhesion And Migration, Negin Baghdadchi

Electronic Theses, Projects, and Dissertations

Glioblastoma multiforme (GBM) is the most lethal primary central nervous system tumor, with median survival after diagnosis of less than 12 months because dissemination into the brain parenchyma limits the long-term effectiveness of surgical resection, and because GBM cells are resistant to radiation and chemotherapy. This sad dismal prognosis for patients with GBM emphasizes the need for greater understand of the fundamental biology of the disease.

Invasion is one of the major causes of treatment failure and death from glioma, because disseminated tumor cells provide the seeds for tumor recurrence. Inflammation is increasingly recognized as an important component of invasion. …
