Time Course Investigation Of The Dermal Leukocyte Response To Lipoteichoic Acid In Chickens, Ian Gilbert

Animal Science Undergraduate Honors Theses

Lipoteichoic acid (LTA) is component of the cell wall of Gram-positive bacteria that stimulates inflammation during bacterial infection. However, few studies have investigated the in vivo immune response to LTA, and none of the in vivo studies done have been performed in birds. For this project, the pulp (a skin-derivative) of growing feathers (GFs) of chickens were used as a test site to investigate the in vivo effects of intradermally injected LTA. In Study 1, the pulp of 12 GFs of 11-week-old Light-brown Leghorn (LBL) males were injected with 10 μL of differing concentrations of LTA (0.1, 1.0, 10, 100 …

Prenatal Exposure To A Climate-Related Disaster Results In Changes Of The Placental Transcriptome And Infant Temperament, Jessica Buthmann, Dennis Huang, Patrizia Casaccia, Sarah O'Neill, Yoko Nomura

Advanced Science Research Center

Maternal stress during pregnancy exerts long-term effects on the mental well-being of the offspring. However, the long-term effect of prenatal exposure on the offspring’s mental status is only partially understood. The placenta plays a vital role in connecting the maternal side to the fetus, thereby serving as an important interface between maternal exposure and fetal development. Here, we profiled the placental transcriptome of women who were pregnant during a hurricane (Superstorm Sandy), which struck New York City in 2012. The offspring were followed longitudinally and their temperament was assessed during the first 6–12 months of age. The data identified a …

Colonic Epithelial Angiotensin-Converting Enzyme 2 (Ace2) Expression In Blacks And Whites: Potential Implications For Pathogenesis Covid-19 Racial Disparities, Mart De La Cruz, David P Nunes, Vaishali Bhardwaj, Deepika Subramanyan, Caroline Zaworski, Priya Roy, Hemant K Roy

Faculty, Staff and Students Publications

BACKGROUND: Covid-19 toll is disproportionate in Blacks although the mechanisms remain incompletely understood. From a biological perspective, several host proteins have received most attention as logical susceptibility targets. Specifically, angiotensin-converting enzyme 2 (ACE2) serves as the epithelial cell receptor and acts in concert with transmembrane protease serine 2 (TMPRSS2). Intriguingly, ACE2 can also suppress the inflammatory response and therefore may impact the severity of Covid-19 infections (from the exuberant immune response a.k.a. "cytokine storm"). We, therefore, assessed expression of ACE2 and TMPRSS2 in Blacks versus Whites.

METHODS: Archived mucosal biopsies from colonoscopic biopsies of visually normal rectal mucosa without concurrent …

The Effects Of Neuronal Growth Factors On Lps-Activated Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Angela Asirvatham Ph.D.

Student Research Poster Presentations 2022

Schwann cells (SCs) are the principal support cells of neurons in the peripheral nervous system, that both myelinate axons for the rapid conduction of electrical impulses as well as assist in axonal repair during nerve injury. During nerve injury, SCs secrete tumor necrosis factor alpha (TNF-α)^1,5,6 and other proinflammatory mediators^1,6, attracting macrophages to the site of injury to induce inflammation and clear myelin debris.^1,6 Once the debris is cleared, the neuron stimulates SC proliferation by secreting neuronal mitogens, such as heregulin^3,4, and an unknown factor that activates the cAMP pathway³, an important …

Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn Henry, Peyton Kimmel, Angela Asirvatham

Student Research Poster Presentations 2022

During peripheral nerve injury, the myelin surrounding the neuronal axons is damaged, initiating an inflammatory response to remove myelin debris. Once myelin debris is cleared, Schwann cells acquire a proliferating phenotype which allows them to grow and divide so that remyelination can occur. The neuron stimulates Schwann cell division by secreting growth factors, like heregulin, and an unknown growth factor that activates the cAMP pathway. Although the role of cAMP in axonal regeneration is well-known, not much has been explored about its function in Schwann cells during nerve injury and inflammation. To simulate an inflammatory environment, the S16 Schwann cell …

Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Mackenzie Wilcox, Angela Asirvatham

SURF Posters 2022

Schwann cells are a type of glial cell in the peripheral nervous system that produce the myelin sheath surrounding neuronal axons. This myelin insulates the neurons and promotes the rapid conduction of electrical impulses throughout the body. Schwann cells have also been found to play a critical role in neuron repair following nerve injury. During nerve injury, the myelin sheath is damaged, stimulating Schwann cells to release cytokines, or inflammatory mediators, that recruit immune cells to the site of injury so that the myelin debris can be cleared, and repair can take place.1 Then neuronal growth is facilitated by heregulin …

Modulation Of Glucose Homeostasis By Nucleotide P2y2 Receptor And Biological Sex, Hailee Anne Marino

Graduate Theses/Dissertations

Recent insights into the pathological role of Nucleotide P2Y₂ receptor suggest P2Y₂R involvement in high fat diet-induced obesity and potentiates insulin resistance. However, these recent insights do not demonstrate how P2Y₂R modulates glucose homeostasis under physiological conditions. Further, it remains unknown how sex biological factors influence P2Y₂R receptor signaling in the regulation of glucose homeostasis. The research objective for the present study is to elucidate the novel roles of P2Y₂ in fasting blood glucose and glucose tolerance (basal insulin sensitivity) under resting conditions in males and females. We expected that under physiological …

INTRODUCTION: Idiopathic pulmonary fibrosis (IPF) is an orphan disease characterized by progressive loss of lung function resulting in shortness of breath and often death within 3-4 years of diagnosis. Repetitive lung injury in susceptible individuals is believed to promote chronic oxidative stress, inflammation, and uncontrolled collagen deposition. Several preclinical and retrospective clinical studies in IPF have reported beneficial outcomes associated with the use of proton pump inhibitors (PPIs) such as esomeprazole. Accordingly, we sought to investigate molecular mechanism(s) by which PPIs favorably regulate the disease process.

METHODS: We stimulated oxidative stress, pro-inflammatory and profibrotic phenotypes in primary human lung epithelial …

Mitochondrial Transfer From Mesenchymal Stem Cells Improves Neuronal Metabolism After Oxidant Injury In Vitro: The Role Of Miro1, Nancy Tseng, Scott C Lambie, Christopher Q Huynh, Bridget Sanford, Manisha Patel, Paco S Herson, D Ryan Ormond

Faculty, Staff and Students Publications

Stroke-induced cerebral ischemia is a major cause of death and disability. The disruption of blood flow results in neuronal and glial cell death leading to brain injury. Reperfusion restores oxygen to the affected tissue, but can also cause damage through an enhanced oxidative stress and inflammatory response. This study examines mitochondrial transfer from MSC to neurons and the role it plays in neuronal preservation after oxidant injury. We observed the transfer of mitochondria from MSC to mouse neurons in vitro following hydrogen peroxide exposure. The observed transfer was dependent on cell-to-cell contact and led to increased neuronal survival and improved …

Links Between Thrombosis And Inflammation In Traumatic Brain Injury, W Brad Hubbard, Jing-Fei Dong, Miguel A Cruz, Rolando E Rumbaut

Faculty, Staff and Students Publications

Traumatic brain injury (TBI) continues to be a major healthcare problem and there is much to be explored regarding the secondary pathobiology to identify early predictive markers and new therapeutic targets. While documented changes in thrombosis and inflammation in major trauma have been well described, growing evidence suggests that isolated TBI also results in systemic alterations in these mechanisms. Here, we review recent experimental and clinical findings that demonstrate how blood-brain barrier dysfunction, systemic immune response, inflammation, platelet activation, and thrombosis contribute significantly to the pathogenesis of TBI. Despite advances in the links between thrombosis and inflammation, there is a …

Inhibition Of Matrix Metalloproteinase-9 Secretion By Dimethyl Sulfoxide And Cyclic Adenosine Monophosphate In Human Monocytes, Darcy Denner, Maria Udan-Johns, Michael Nichols

Chemistry & Biochemistry Faculty Works

BACKGROUND Matrix metalloproteinases (MMPs), including MMP-9, are an integral part of the immune response and are upregulated in response to a variety of stimuli. New details continue to emerge concerning the mechanistic and regulatory pathways that mediate MMP-9 secretion. There is significant evidence for regulation of inflammation by dimethyl sulfoxide (DMSO) and 3',5'-cyclic adenosine monophosphate (cAMP), thus investigation of how these two molecules may regulate both MMP-9 and tumor necrosis factor α (TNFα) secretion by human monocytes was of high interest. The hypothesis tested in this study was that DMSO and cAMP regulate MMP-9 and TNFα secretion by distinct mechanisms. …

Progressive remodeling of the heart, resulting in cardiomyocyte (CM) loss and increased inflammation, fibrosis, and a progressive decrease in cardiac function, are hallmarks of myocardial infarction (MI)-induced heart failure. We show that MCB-613, a potent small molecule stimulator of steroid receptor coactivators (SRCs) attenuates pathological remodeling post-MI. MCB-613 decreases infarct size, apoptosis, hypertrophy, and fibrosis while maintaining significant cardiac function. MCB-613, when given within hours post MI, induces lasting protection from adverse remodeling concomitant with: 1) inhibition of macrophage inflammatory signaling and interleukin 1 (IL-1) signaling, which attenuates the acute inflammatory response, 2) attenuation of fibroblast differentiation, and 3) promotion …

The Impact Of Microbial Experience On The Murine Innate Immune Response, Cody Thomas Morrison

Masters Theses

The hygiene hypothesis predicts that certain environmental factors shape overall immune system function in animals and humans. While current specific pathogen free (SPF) mouse models are invaluable for studying the immune system, they have limitations for comparison with humans who have microbial exposures throughout their lifetimes. Several studies have shown that the composition of the immune system of SPF mice more closely resembles that of newborns, whereas the immune system from mice exposed to microbial pathogens more closely reflect adult immunity. In this study we have established a model using traditional SPF mice (“clean mice”) and SPF mice that were …

Prevention Of Chronic Inflammation By Targeting Macrophage Integrin Adb2, Cady Forgey

Electronic Theses and Dissertations

Macrophage integrin a_Db₂ promotes macrophage retention and accumulation within inflamed tissue, a key event in development of chronic inflammation. Recently, the P5 peptide was identified as a specific inhibitor for integrin a_Db₂ interaction with 2-(ω-carboxyethyl) pyrole (CEP), a ligand at inflammatory sites. This thesis aims to identify integrin a_D I-domain amino acids involved in binding P5 peptide and likewise to CEP. We propose that non-conserved, basic amino acids of the integrin a_Db₂ I-domain are responsible for binding to P5 peptide and likewise to CEP. Eight amino acids were analyzed by …

Young Versus Aged Microbiota Transplants To Germ-Free Mice: Increased Short-Chain Fatty Acids And Improved Cognitive Performance, Juneyoung Lee, Venugopal R Venna, David J Durgan, Huanan Shi, Jacob Hudobenko, Nagireddy Putluri, Joseph Petrosino, Louise D Mccullough, Robert M Bryan

Faculty, Staff and Students Publications

Aging is associated with cognitive decline and decreased concentrations of short-chain fatty acids (SCFAs) in the gut. SCFAs are significant in that they are protective to the gut and other organs. We tested the hypothesis that the aged gut microbiome alone is sufficient to decrease SCFAs in the host and produce cognitive decline. Fecal transplant gavages (FTGs) from aged (18–20 months) or young (2–3 months) male C57BL/6 mice into germ-free male C57BL/6 mice (N = 11 per group) were initiated at ~3 months of age. Fecal samples were collected and behavioral testing was performed over the study period. Bacterial community …

Role Of Ceramide-1 Phosphate In Regulation Of Sphingolipid And Eicosanoid Metabolism In Lung Epithelial Cells, Brittany A. Dudley

USF Tampa Graduate Theses and Dissertations

Ceramide 1-Phosphate (C1P) is a sphingolipid metabolite which plays a large role in inflammation, cell survival and proliferation¹. C1P is known to have both pro- and anti-apoptotic roles in lung cancer cells, governed by ceramide kinase (CERK), upstream of precursor ceramide (Cer)². Previous work reveals C1P serves as the liaison between sphingolipid and eicosanoid synthesis, by decreasing the dissociation rate of group IVA cytosolic PLA₂ (cPLA_2α) from the Golgi membrane, C1P directly activates this phospholipase for downstream eicosanoid synthesis and subsequent inflammatory response³. CERK has been discovered to modulate eicosanoid synthesis, …

Despite being the frontline therapy for type 2 diabetes, the mechanisms of action of the biguanide drug metformin are still being discovered. In particular, the detailed molecular interplays between the AMPK and the mTORC1 pathway in the hepatic benefits of metformin are still ill defined. Metformin-dependent activation of AMPK classically inhibits mTORC1 via TSC/RHEB, but several lines of evidence suggest additional mechanisms at play in metformin inhibition of mTORC1. Here we investigated the role of direct AMPK-mediated serine phosphorylation of RAPTOR in a new

BACKGROUND: Risk of stroke-related morbidity and mortality increases significantly with age. Aging is associated with chronic, low-grade inflammation, which is thought to contribute to the poorer outcomes after stroke seen in the elderly. Histamine (HA) is a major molecular mediator of inflammation, and mast cells residing in the gut are a primary source of histamine.

METHODS: Stroke was induced in male C57BL/6 J mice at 3 months (young) and 20 months (aged) of age. Role of histamine after stroke was examined using young (Yg) and aged (Ag) mice; mice underwent MCAO surgery and were euthanized at 6 h, 24 h, …

Protection Against Atherosclerosis By A Non-Native Pentameric Crp That Shares Its Ligand Recognition Functions With An Evolutionarily Distant Crp, Asmita Pathak

Electronic Theses and Dissertations

C-reactive protein (CRP) is an acute phase protein of the innate immune system that has been evolutionarily conserved. Human CRP is known to exist in two different pentameric conformations; native CRP and non-native CRP that possess differential ligand recognition functions. The structure of CRP evolved from arthropods to humans, in terms of subunit composition, disulfide bonds, and glycosylation pattern. Along with change in structure, the gene expression pattern of CRP also evolved from a constitutive protein in lower invertebrates to an acute phase protein in humans. The objective of this study was to determine the function of a non-native pentameric …

Losartan Rescues Inflammation-Related Mucociliary Dysfunction In Relevant Models Of Cystic Fibrosis, Michael D Kim, Nathalie Baumlin, Makoto Yoshida, Deepika Polineni, Sebastian F Salathe, Joseph K David, Charles A Peloquin, Adam Wanner, John S Dennis, Juliette Sailland, Philip Whitney, Frank T Horrigan, Juan R Sabater, William M Abraham, Matthias Salathe

Faculty, Staff and Students Publications

Rationale: Despite therapeutic progress in treating cystic fibrosis (CF) airway disease, airway inflammation with associated mucociliary dysfunction remains largely unaddressed. Inflammation reduces the activity of apically expressed large-conductance Ca²⁺-activated and voltage-dependent K⁺ (BK) channels, critical for mucociliary function in the absence of CFTR (CF transmembrane conductance regulator).

Objectives: To test losartan as an antiinflammatory therapy in CF using CF human bronchial epithelial cells and an ovine model of CF-like airway disease.

Methods: Losartan’s antiinflammatory effectiveness to rescue BK activity and thus mucociliary function was tested in vitro using primary, fully redifferentiated human airway epithelial cells homozygous for …

The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine

Theses and Dissertations

Patients with severe lung pathologies, such as Acute Respiratory Distress Syndrome (ARDS), often require mechanical ventilation as a clinical intervention; however, this procedure frequently exacerbates the original pulmonary issue and produces an exaggerated inflammatory response that potentially leads to sepsis, multisystem organ failure, and mortality. This acute lung injury (ALI) condition has been termed Ventilator-Induced Lung Injury (VILI). Alveolar overdistension, cyclic atelectasis, and biotrauma are the primary injury mechanisms in VILI that lead to the loss of alveolar barrier integrity and pulmonary inflammation. Stress and strains during mechanical ventilation are believed to initiate alveolar epithelial mechanotransduction signaling mechanisms that contribute …

Transcription Regulation Of Human Il1b Gene In Monocytes And Lymphoid Cd4 T Cells, Sree H. Pulugulla

Electronic Theses and Dissertations

Cytokines are key regulators of the inflammatory response and play an important role in facilitating intercellular communication between various immune cell types. Interleukin‑1β (IL‑1β) is a potent pro-inflammatory cytokine that is required for robust initiation of innate immune response and subsequent development of adaptive immunity. IL-1β is first synthesized as an inactive cytoplasmic, non‑glycosylated, precursor molecule (proIL‑1β) by monocytes and macrophages in response to invading pathogenic microbes. The activation of caspase‑1 by inflammasomes cleaves proIL-1β into mature biologically active IL-1β that is released from cells via a non-classical, endoplasmic reticulum‑independent secretory pathway directly from the cytoplasm via Gasdermin D membrane …

Using Lipidomics To Characterize The Inflammatory Mechanisms In Sepsis And Pre-Eclampsia, Daniel Stephenson

Lipidomics, a rapidly developing field of study, focuses on the classification and quantitation of lipid species. Lipidomics has emerged in the forefront of scientific research due to the key roles that lipids play in metabolism, cancer, and disease. Using mass spectrometry as a tool for analysis, understanding the role eicosanoids and sphingolipids play has advanced rapidly. Being able to observe these small molecules in vivo has led to better understanding of several lipid-driven mechanisms and identification of eicosanoid and sphingolipid biomarkers in neurodegenerative disease, cancer, sepsis, wound healing, and pre-eclampsia. In the studies herein, we developed targeted mass spectrometric methods …

Effect Of Osteoactivin And Bone Morphogenetic Protein-2 On Soft Tissue In Rat Spinal Fusion Model, Andrew Ohliger

Williams Honors College, Honors Research Projects

Osteoinductive therapeutic strategies are essential for the bone healing process and are applicable in multiple orthopaedic procedures. The novel protein Osteoactivin (OA) has proven to stimulate osteoblast differentiation and function in vitro and bone regeneration in vivo in the rat model. More recently, OA has shown significant bone regeneration ability in sheep. The goal of this study is the comparison of osteoactivin with bone morphogenetic protein-2 (BMP-2) in the rat spinal fusion model.

The Balance Between Prostaglandin E2 Ep3 And Ep4 Receptors Determines Severity Of Cardiac Damage In Myocardial Infarction And An Angiotensin Ii-Induced Model Of Hypertension, Timothy Dean Bryson

Wayne State University Dissertations

According to the center for disease control about 610,000 people die every year in the United States from heart disease, of which, coronary heart disease is the most common form. One major risk factor for heart attack is hypertension, which affects nearly half of all Americans [472, 473]. PGE2 plays an important role in regulating cardiovascular function and mediating inflammation, both of which contribute to the development of hypertension and/or heart disease. Prostaglandin E2 can act as a vasodilator or vasoconstrictor depending on which of its receptor subtypes are activated.

In general, activation of the EP1 and EP3 receptors is …

Periodontitis, which is a chronic infection and disease of the periodontium, is a significant global health burden and is linked to other chronic health conditions such as diabetes and cardiovascular diseases. Dietary polyphenols present in a wide variety of plant-based foods, herbs, and botanicals have been shown to exert antimicrobial, anti-inflammatory, and reduced osteoclast and alveolar bone loss activities in animal models of periodontitis. Polyphenol-containing beverages and foods especially green tea and its active catechin epigallocatechin-3-gallate, cranberries, pomegranates, and fruit and vegetable extracts have reported bacteriostatic/bactericidal activity against microbial species such as P. gingivalis and shown total bacterial burden in …

Biological Clocks, Inflammation, And Multiorgan Damage In Sickle Cell Disease, Morayo Adebiyi

Dissertations and Theses (Open Access)

Sickle cell disease (SCD) is a dangerous condition caused by a genetic mutation on the human beta-globin gene that contributes to erythrocyte sickling, the hallmark of the disease. Previous metabolomics studies have confirmed that elevated sphingosine kinase 1 (SphK1) mediates sphingosine-1-phosphate (S1P) production to promote erythrocyte sickling. S1P signals via five S1P receptors (S1PR) regulates several pathophysiological functions.

In the first chapter of this dissertation, I explored the role of S1PRs in SCD by utilizing pharmacologic and genetic tools. To determine the role of S1P-S1PRs signaling in SCD, I treated humanized Berkeley sickle mice (Berkeley HBS mice), with FTY720, a …

5-Lipoxygenase (5-Lox)-5-Lipoxygenase Activating Protein (Flap)-Nanodisc Complex: A Model For The 5-Lox-Flap Interaction, Erin Elizabeth Schexnaydre

LSU Doctoral Dissertations

Leukotrienes (LT) are lipid mediators of the inflammatory response that play important roles in diseases such as asthma and atherosclerosis. Leukotriene A4 (LTA₄) is synthesized from arachidonic acid (AA) by 5-lipoxygenase (5-LOX) with the help of 5-lipoxygenase activating protein (FLAP), a trimeric nuclear transmembrane protein. Exactly how 5-LOX and FLAP interact is not well understood, however FLAP is essential for the production of leukotrienes in vivo. I used nanodiscs (NDs), engineered membrane systems, as a tool to study the 5-LOX-FLAP interaction. FLAP was incorporated into NDs with a phospholipid composition to mimic of the nuclear membrane. Structural features …
