Evaluating The Efficacy And Safety Of Inactivated Dengue Vaccines In Vulnerable Populations, Alaa Daghash

Honors Undergraduate Theses

Dengue virus is a mosquito-borne flavivirus responsible for over 390 million annual cases worldwide. While there are live-attenuated vaccines available to prevent dengue, none are currently approved for use in the United States, and existing platforms pose significant risks of viral reactivation and antibody-dependent enhancement in vulnerable populations, such as pregnant women, children under the age of nine, and the immunocompromised. This widespread exclusion of vulnerable populations exposes a significant vaccine equity gap in dengue prevention, as the populations most at risk for severe dengue are the same ones who are currently excluded from vaccination. In this study, I conducted …

Polymorphic Α-Glucans As Structural Scaffolds In Cryptococcus Cell Walls For Chitin, Capsule, And Melanin: Insights From 13c And 1h Solid-State Nmr, Ankur Ankur, Jayasubba Reddy Yarava, Isha Gautam, Faith J. Scott, Frederic Mentink-Vigier, Christine Chrissian, Li Xie, Dibakar Roy, Ruth E. Stark, Tamara L. Doering, Ping Wang, Tuo Wang

Cryptococcus species are major fungal pathogens responsible for life-threatening infections in approximately a million individuals globally each year, with alarmingly high mortality rates. These fungi are distinguished by a distinctive cell wall architecture further reinforced by two virulence-associated layers, melanin and capsule, rendering them insensitive to antifungal agents targeting the cell wall, such as echinocandins. The molecular interplay between these three biomolecular layers remains poorly understood. Here we employ solid-state NMR spectroscopy to examine intact cells of both wild-type and capsule-deficient strains of C. neoformans, along with melanized cells. High-resolution 13C and 1H data revealed five distinct structural forms of …

Exploring The Mechanisms Of Varicella-Zoster Virus Pathogenesis And Its Potential Role In Oncogenesis, Fernando Cisneros, Blake Martin

Research Symposium

Background: Varicella-zoster virus (VZV) is a highly prevalent pathogen primarily recognized for causing chickenpox during primary infection and herpes zoster (HZ), also known as shingles, upon reactivation. While post-infectious complications of VZV, such as encephalitis, pneumonia, and post-herpetic neuralgia, are well-established, recent large population-based studies suggest that HZ may increase the risk of occult cancers. Emerging evidence suggests that VZV may modulate key oncogenic pathways, such as the inhibition of apoptosis, alteration of cell cycle regulatory enzymes, and interference with immunosurveillance, which could potentially promote cancer development. These findings indicate that VZV’s role in cancer biology may involve direct cellular …

Combination Therapy Of Ido1 Inhibition And Anti-Pd1 Mediates Anti-Tumor Immunity By Promoting Memory Immunity Development And Cytotoxicity Of Γδ T And Nk Cells Via Il-2 Signaling And By Overcoming Pro-Tumor Effects Of Tgf-Β Signaling, Hyuk Jee

Dartmouth College Master’s Theses

Cutaneous melanoma is the most aggressive form of skin cancer even though it takes only about 1% of all skin cancers. Even among all cutaneous melanomas, NRAS-mutant melanoma is more aggressive than any other, and about 10-25% of all cutaneous melanoma cases have mutations in NRAS. NRAS is a member of the RAS family of proto-oncogenic GTPase proteins, and it plays a key role in signal transduction pathways responsible for cellular survival, proliferation, and metabolism. Immunotherapy is the first line of defense against NRAS-mutant melanoma because, despite tremendous efforts made for decades, it has not been successful to develop small …

Adaptative Survival Of Aspergillus Fumigatus To Echinocandins Arises From Cell Wall Remodeling Beyond Β−1,3-Glucan Synthesis Inhibition, Malitha C. Dickwella Widanage, Isha Gautam, Daipayan Sarkar, Frederic Mentink-Vigier, Josh V. Vermaas, Shi You Ding, Andrew S. Lipton, Thierry Fontaine, Jean Paul Latgé, Ping Wang, Tuo Wang

School of Graduate Studies Faculty Publications

Antifungal echinocandins inhibit the biosynthesis of β−1,3-glucan, a major and essential polysaccharide component of the fungal cell wall. However, the efficacy of echinocandins against the pathogen Aspergillus fumigatus is limited. Here, we use solid-state nuclear magnetic resonance (ssNMR) and other techniques to show that echinocandins induce dynamic changes in the assembly of mobile and rigid polymers within the A. fumigatus cell wall. The reduction of β−1,3-glucan induced by echinocandins is accompanied by a concurrent increase in levels of chitin, chitosan, and highly polymorphic α−1,3-glucans, whose physical association with chitin maintains cell wall integrity and modulates water permeability. The rearrangement of …

Serine Deamination By Human Serine Racemase Synergizes With Antibiotics To Curtail The Replication Of Chlamydia Trachomatis, Patricia D. Mott, Arnold H. Zea, Jamiya Lewis, Oygul Mirzalieva, Ashok A. Aiyar

School of Medicine Faculty Publications

The obligate intracellular bacterium, Chlamydia trachomatis, has evolved to depend on its human host for many metabolites, including most amino acids and three of the four nucleotides. Given this, it is not surprising that depletion of a single amino acid in the host cell growth medium blocks chlamydial replication. Paradoxically, supra-normal levels of some amino acids also block productive replication of Chlamydia. Here, we have determined how elevated serine levels, generated by exogenous supplementation, impede chlamydial inclusion development and reduce the generation of infectious progeny. Our findings reveal that human serine racemase, which is broadly expressed in multiple tissues, potentiates …

Ftsk Regulates The Assembly Of The Division Machinery In The Ftsz-Less Chlamydia Trachomatis, Mckenna Katherine Harpring

Theses and Dissertations (ETD)

In evolving to obligate intracellular dependence, Chlamydia trachomatis serovar L2 (Ct), has eliminated several gene products essential for cell division in most other bacteria, including FtsZ, the central coordinator of divisome assembly. In the absence of FtsZ, we show that divisome assembly in Ct is initiated by FtsK, a chromosomal translocase. Chlamydial FtsK forms discrete foci at the septum and at the base of the progenitor mother cell, and our data indicate that FtsK foci at the base of the mother cell mark the location of nascent divisome complexes that form at the site where a daughter cell will emerge …

Investigating The Role Of Maternal Adiposity On Human Breast Milk And Preterm Infant Stool Short Chain Fatty Acid And Microbiome Profiles, Kristy L. Thomas

Electronic Theses and Dissertations

Preterm birth is the number one cause of death in neonates, accounting for 35% of neonatal mortality. The preterm birth rate in the U.S. in 2021 was 10.5%, disproportionally affected by race and ethnicity. Obese women have an increased risk of preterm pregnancy, and if delivered before 37 weeks of gestation, the offspring have higher rates of complications that extend from the neonatal period into life-long metabolic and immune adverse outcomes. In the early months after delivery, preterm infants have higher rates of adverse health outcomes than term infants, including infections, extrauterine growth restrictions, respiratory, metabolic, and neurological complications, necrotizing …

Magnesium Increases Numbers Of Foxp3+ Treg Cells And Reduces Arthritis Severity And Joint Damage In An Il-10-Dependent Manner Mediated By The Intestinal Microbiome, Teresina Laragione, Carolyn Harris, Nasim Azizgolshani, Christine Beeton, Gerold Bongers, Percio S Gulko

Faculty, Staff and Students Publications

BACKGROUND: Rheumatoid arthritis (RA) is a common autoimmune disease with emerging environmental and microbiome risk factors. The western diet is typically deficient in magnesium (Mg), and there is some evidence suggesting that Mg may have anti-inflammatory properties. But the actual role of Mg supplementation in arthritis or in T cell subsets has not been explored.

METHODS: We investigated the role of a high Mg diet in two different mouse models of RA induced with the KRN serum, and collagen-induced arthritis. We also characterized the phenotypes of splenocytes, gene expression, and an extensive intestinal microbiome analyses including fecal material transplantation (FMT). …

Effects Of Atrazine Exposure On Human Bone Marrow-Derived Mesenchymal Stromal Cells Assessed By Combinatorial Assay Matrix, Crystal C Uwazie, Bonnie M Pirlot, Tyler U Faircloth, Mihir Patel, Rhett N Parr, Halie M Zastre, Peiman Hematti, Guido Moll, Devi Rajan, Raghavan Chinnadurai

Faculty, Staff and Student Publications

INTRODUCTION: Mesenchymal Stromal/Stem cells (MSCs) are an essential component of the regenerative and immunoregulatory stem cell compartment of the human body and thus of major importance in human physiology. The MSCs elicit their beneficial properties through a multitude of complementary mechanisms, which makes it challenging to assess their phenotype and function in environmental toxicity screening. We here employed the novel combinatorial assays matrix approach/technology to profile the MSC response to the herbicide Atrazine, which is a common environmental xenobiotic, that is in widespread agricultural use in the US and other countries, but banned in the EU. Our here presented approach …

Genomic Features Underlie The Co-Option Of Sva Transposons As Cis-Regulatory Elements In Human Pluripotent Stem Cells, Samantha M Barnada, Andrew Isopi, Daniela Tejada-Martinez, Clément Goubert, Sruti Patoori, Luca Pagliaroli, Mason Tracewell, Marco Trizzino

Department of Biochemistry and Molecular Biology Faculty Papers

Domestication of transposable elements (TEs) into functional cis-regulatory elements is a widespread phenomenon. However, the mechanisms behind why some TEs are co-opted as functional enhancers while others are not are underappreciated. SINE-VNTR-Alus (SVAs) are the youngest group of transposons in the human genome, where ~3,700 copies are annotated, nearly half of which are human-specific. Many studies indicate that SVAs are among the most frequently co-opted TEs in human gene regulation, but the mechanisms underlying such processes have not yet been thoroughly investigated. Here, we leveraged CRISPR-interference (CRISPRi), computational and functional genomics to elucidate the genomic features that underlie SVA domestication …

Antigen Staining For Detection Of Muc13 And Muc16 Expression In Carcinoma Tissue, Jose A. Benitez

MEDI 9331 Scholarly Activities Clinical Years

MUC13 and MUC16 are epithelial expressed proteins implicated in various carcinomas. Overexpression of these biomarkers appear to play a role in tumor growth; this discovery has paved a road for multiple studies discussing the potential of targeting mucin proteins and optimize immunotherapy approaches against carcinomas. Our study serves to investigate the level of expression of MUC13 and MUC16 in cancerous and normal tissue and to discuss the implications our findings may have for the utilization of these biomarkers for cancer therapy.

The Crosstalk Between Insulin Resistance, Systemic Inflammation, Redox Imbalance And The Thyroid In Subjects With Obesity, Nicoleta Răcătăianu, Nicoleta Valentina Leach, Sorana D. Bolboacă, Maria Loredana Soran, Mirela Flonta, Ana Valea, Andrada-Luciana Lazăr, Cristina Ghervan

Journal of Mind and Medical Sciences

We aimed at assessing the interaction between visceral adipose tissue (VAT), insulin resistance (IR), circulating levels of monocyte chemoattractant protein-1 (MCP-1) and malondialdehyde (MDA) and the thyroid parameters in obese subjects. Methods. Obese subjects without thyroid pathologies or diseases associated with systemic inflammation and OS were recruited. Insulinemia, visceral fat thickness, metabolic and thyroid parameters were assayed. Circulating levels of MCP-1 and MDA were used to quantify inflammation and OS. Results. A number of 160 obese subjects were included. The MCP-1 level increased with the degree of obesity and HOMA-IR. MCP 1 was positively associated with antithyroperoxidase antibody (TPOab) levels …

The State Of The Translational Chaperone Icd-1 During Apoptosis In Caenorhabditis Elegans, Kyle Cicalese

Senior Honors Projects, 2010-2019

The unfolded protein response (UPR) is a signal transduction cascade that mitigates low levels of misfolded protein stress in the endoplasmic reticulum (ER) in an effort to save the affected cell, while prolonged and/or acute ER stress leads to UPR-initiated apoptosis (programmed cell death). One putative step driving apoptosis is the cleavage of chaperones, proteins tasked to help misfolded proteins refold, by caspases, proteases essential to the execution of apoptosis. We are studying the nascent polypeptide-associated complex (NAC), a heterodimeric chaperone complex essential for viability, to determine if its beta subunit is cleaved by caspases during apoptosis to prevent the …

Tumor Immunotherapy: Mechanisms Of Acquired Resistance And Characterization Of Immune Related To Xicities, Ashvin Jaiswal

Dissertations and Theses (Open Access)

Tumor immunotherapy has shown very promising clinical benefit across an array of cancers; however, two major challenges remain unresolved in the field. First, many patients do not respond to therapy at all or relapse after a period of remission. Second, there are often dose-limiting immune related adverse effects associated with immunomodulation.

In order to understand the mechanisms employed by tumors to evade immunotherapeutic responses, we established a murine model of melanoma designed to elucidate the molecular mechanisms underlying immunotherapy resistance. Through multiple in vivo passages, we selected a B16 melanoma tumor line that evolved complete resistance to combination blockade of …

The 11s Proteasomal Activator Regγ Impacts Polyglutamine-Expanded Androgen Receptor Aggregation And Motor Neuron Viability Through Distinct Mechanisms., Jill M. Yersak, Heather L. Montie, Erica S. Chevalier-Larsen, Yuhong Liu, Lan Huang, Martin Rechsteiner, Diane E. Merry

Department of Biochemistry and Molecular Biology Faculty Papers

Spinal and bulbar muscular atrophy (SBMA) is caused by expression of a polyglutamine (polyQ)-expanded androgen receptor (AR). The inefficient nuclear proteasomal degradation of the mutant AR results in the formation of nuclear inclusions containing amino-terminal fragments of the mutant AR. PA28γ (also referred to as REGγ) is a nuclear 11S-proteasomal activator with limited proteasome activation capabilities compared to its cytoplasmic 11S (PA28α, PA28β) counterparts. To clarify the role of REGγ in polyQ-expanded AR metabolism, we carried out genetic and biochemical studies in cell models of SBMA. Overexpression of REGγ in a PC12 cell model of SBMA increased polyQ-expanded AR aggregation …

Mechanism Of Chimeric Vaccine Mediated Immune Suppression Of Human Dendritic Cells, Jacques Christian Mbongue

Loma Linda University Electronic Theses, Dissertations & Projects

Type 1 diabetes mellitus is a chronic inflammatory disease in which insulin producing β-cells of the pancreatic islets are killed by autoreactive cells of the immune system in response to a loss of tolerance. Dendritic cells (DC) interact predominantly with naïve T cells to regulate the delicate balance between immunity and tolerance required to maintain immunological homeostasis. In this dissertation, immature human dendritic cells (iDC) were inoculated with a chimeric fusion protein vaccine containing the pancreatic β-cell auto-antigen proinsulin linked to a mucosal adjuvant the cholera toxin B subunit (CTB-INS). Proteomic analysis of vaccine inoculated DCs revealed strong up-regulation of …

Interaction Between Two E3 Ligases, Nedd8ylated Cullin And Hhari, Kheewoong Baek

Theses and Dissertations (ETD)

RBR (RING1-in between RING-RING2) is a special type of E3 ubiquitin ligase containing three zinc-binding RING (Really Interesting New Gene) domains, while adopting mechanisms of HECT (Homologous to E6-AP Carboxyl Terminus) for substrate ubiquitination. Most well known RBRs include Parkin and HOIP, which are associated with Parkinson’s disease and innate immune deficiency. However, it is not well known how the RBR proteins gain activity, as they are known to be autoinhibited. Here I show that a specific F430A, E431A, E503A triple mutation of RBR protein HHARI (Human homologue of Ariadne) and its interaction with NEDD8ylated cullin RING ligase can both …

Pten Signaling In Regulatory T Cells And Inflammatory Disease, Sharad Krishna Shrestha

Theses and Dissertations (ETD)

Regulatory T (Treg) cells suppress CD4+ T cell responses during homeostasis and inflammation to prevent autoimmunity and other immune disorders. Although the transcriptional and epigenetic programs impacting Treg cell function have been extensively studied, the signaling and metabolic pathways underlying Treg stability and function are not fully understood. In this study, we determined the role of the phosphatase PTEN in Treg cells. We found that specific depletion of PTEN in Treg cells results in excessive TH1 and T follicular helper cells (TFH) responses, associated with elevated germinal center (GC) B cells and spontaneous development of autoimmune and lymphoproliferative disease in …

Development Of Oral Vaccines Against Lyme Disease, Rita Raquel Dos Anjos De Carvalho E Melo

Theses and Dissertations (ETD)

Lyme Disease, caused by the spirochete Borrelia burgdorferi, is the most common vector-borne disease in the United States and Europe. If left untreated, it can lead to permanent damage to the nervous and musculoskeletal systems. In some cases, patients that receive the recommended antibiotic therapy develop a debilitating health condition associated with substantial health care costs. Despite current preventive measures, the incidence and the geographic distribution of Lyme Disease continues to increase. Recent estimates from CDC suggest that the true number of cases of Lyme Disease in the US is approximately 300,000 per year. Yet, there is currently no vaccine …

Cyclic Peptide-Capped Gold Nanoparticles For Enhanced Sirna Delivery, Amir Nasrolahi Shirazi, Karissa L. Paquin, Niall G. Howlett, Dindyal Mandal, Keykavous Parang

Pharmacy Faculty Articles and Research

Previously, we have reported the synthesis of a homochiral L-cyclic peptide [WR]5 and its use for delivery of anti-HIV drugs and biomolecules. A physical mixture of HAuCl4 and the peptide generated peptide-capped gold nanoparticles. Here, [WR]5 and [WR]5-AuNPs were tested for their efficiency to deliver a small interfering RNA molecule (siRNA) in human cervix adenocarcinoma (HeLa) cells. Flow cytometry investigation revealed that the intracellular uptake of a fluorescence-labeled non-targeting siRNA (200 nM) was enhanced in the presence of [WR]5 and [WR]5-AuNPs by 2- and 3.8-fold when compared with that of siRNA alone after 24 h incubation. Comparative toxicity results showed …

A Novel Mechanism Of Enhanced Susceptibility To Bacterial Pneumonia In Influenza-Infected Hosts, Hazem Elsayed Ghoneim

Theses and Dissertations (ETD)

Viruses such as influenza suppress host immune function by a variety of methods. This may result in a significant morbidity through several pathways, including facilitation of secondary bacterial pneumonia from pathogens such as Streptococcus pneumoniae. Lungresident alveolar macrophages (AMs) act as the first line of innate cellular immunity against respiratory bacterial pathogens, including pneumococcus. Therefore, they represent an attractive target for study Before investigating the impact of influenza infection on resident AMs, we first characterized different subsets of lung-resident macrophages in naïve mice using a novel in vivo labeling approach in conjunction with multicolor flow cytometric analysis and confocal microscopic …

The contractile and relaxant responses of the tissue were measured using isometric transducers coupled with Power-Lab data acquisition system. The anti-inflammatory effect was evaluated in carrageenan-induced rat paw edema model, while the …

Domain Requirements For The Diverse Immune Regulatory Functions Of Foxp3, Wei-Ping Zeng, Vincent E. Sollars, Andrea Del Pilar Belalcazar

Biochemistry and Microbiology

Foxp3 is responsible for the major immunological features of Treg cells, including hypoproliferation in vitro, immune suppression of conventional T cells and resistance to Th2 cell differentiation. In addition to the Forkhead domain, the Foxp3 protein contains the N-terminal, zinc finger and leucine zipper domains. To understand how these domains contribute to Foxp3 functions, we systematically compared the roles of these domains in determining the 3 major immunological features of Treg cells. We designed a bridge-mediated mutagenesis method to generate Foxp3 mutants with complete deletion of each of the domains. CD4 T cells expressing the Foxp3 mutant with deletion of …

Tca Cycle Inactivation In Staphylococcus Aureus Alters Nitric Oxide Production In Raw 264.7 Cells, Chandirasegaran Massilamany, Arunakumar Gangaplara, Donald J. Gardner, James M. Musser, David J. Steffen, Greg A. Somerville, Jay Reddy

Jay Reddy Publications

Inactivation of the Staphylococcus aureus tricarboxylic acid (TCA) cycle delays the resolution of cutaneous ulcers in a mouse soft tissue infection model. In this study, it was observed that cutaneous lesions in mice infected with wild-type or isogenic aconitase mutant S. aureus strains contained comparable inflammatory infiltrates, suggesting the delayed resolution was independent of the recruitment of immune cells. These observations led us to hypothesize that staphylococcal metabolism can modulate the host immune response. Using an in vitro model system involving RAW 264.7 cells, the authors observed that cells cultured with S. aureus aconitase mutant strains produced significantly lower amounts …

Detection Of Autoreactive Cd4 T Cells Using Major Histocompatibility Complex Class Ii Dextramers, Chandirasegaran Massilimany, Bijaya Upadhyaya, Arunakumar Gangaplara, Charles Kuszynski, Jay Reddy

Jay Reddy Publications

Background: Tetramers are useful tools to enumerate the frequencies of antigen-specific T cells. However, unlike CD8 T cells, CD4 T cells - especially self-reactive cells - are challenging to detect with major histocompatibility complex (MHC) class II tetramers because of low frequencies and low affinities of their T cell receptors to MHCpeptide complexes. Here, we report the use of fluorescent multimers, designated MHC dextramers that contain a large number of peptide-MHC complexes per reagent.

Results: The utility of MHC dextramers was evaluated in three autoimmune disease models: 1) proteolipid protein (PLP) 139-151-induced experimental autoimmune encephalomyelitis in SJL/J (H-2^s) …
