Basigin As An Immune Mediator In The Cns, Alicia Gonzalez Jan 2020

Basigin As An Immune Mediator In The Cns, Alicia Gonzalez

UNF Graduate Theses and Dissertations

Chronic inflammation is a hallmark of many neurodegenerative disorders. Although the central nervous system (CNS) can stave peripheral pathogens from crossing the blood-brain barrier (BBB) through a network of continuous endothelia, astrocytes, and pericytes, prolonged exposure to a pathogen can comprise this barrier. Basigin, a cell adhesion molecule, is found on the surface of endothelial cells and has been demonstrated to interact with toll-like receptor 4 (TLR4). TLR4 recognizes lipopolysaccharide (LPS), found on the outer membrane of Gram-negative bacteria. The activation of TLR4 produces pro-inflammatory cytokines, like IL-6. The present study aims to address the expression pattern of Basigin gene …


The Immunological Response To Chronic Stress In Obese Mice, Matthew Corey Parsley Jan 2020

The Immunological Response To Chronic Stress In Obese Mice, Matthew Corey Parsley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obesity and psychological stress are major risk factors for cardiovascular disease and have a positive correlation with vascular dysfunction. This functional deficit has been linked to a pro-inflammatory milieu, exacerbated by an upregulation of pro-inflammatory cytokines. Febuxostat, a xanthine oxidase inhibitor, has been shown to rescue vascular impairment in these models. The purpose of this study was to examine the individual and combined effects of obesity and chronic stress on neuroimmune cell populations, and assess if febuxostat is able mediate immune alterations.

Male mice (n=48) were assigned into either normal chow (lean) and high-fat diet (obese) groups. The lean animals …

Chronic critical illness is a global clinical issue affecting millions of sepsis survivors annually. Survivors report chronic skeletal muscle weakness and development of new functional limitations that persist for years. To delineate mechanisms of sepsis-induced chronic weakness, we first surpassed a critical barrier by establishing a murine model of sepsis with ICU-like interventions that allows for the study of survivors. We show that sepsis survivors have profound weakness for at least 1 month, even after recovery of muscle mass. Abnormal mitochondrial ultrastructure, impaired respiration and electron transport chain activities, and persistent protein oxidative damage were evident in the muscle of …


Stimulatory Effect Of 5-Hydroxytryptamine (5-Ht) On Rat Capsaicin-Sensitive Lung Vagal Sensory Neurons Via Activation Of 5-Ht3 Receptors, Chun-Chun Hsu, Ting Ruan, Lu-Yuan Lee, You Shuei Lin May 2019

Stimulatory Effect Of 5-Hydroxytryptamine (5-Ht) On Rat Capsaicin-Sensitive Lung Vagal Sensory Neurons Via Activation Of 5-Ht3 Receptors, Chun-Chun Hsu, Ting Ruan, Lu-Yuan Lee, You Shuei Lin

Physiology Faculty Publications

5-hydroxytryptamine (5-HT) is an inflammatory mediator known to be released in lung. Capsaicin-sensitive lung vagal (CSLV) afferents function as a primary sensor for detecting chemical stimuli and produce consequent reflexes during lung inflammation. To characterize the effect of 5-HT on CSLV afferents, responses of cardiorespiratory reflexes and single-unit C-fiber afferents to right-atrial injections of 5-HT were investigated in anesthetized Sprague-Dawley rats. Bolus injection of 5-HT (8 μg/kg) caused an immediate augmented breath and apnea, accompanied by hypotension and bradycardia. These initial responses were then followed by a brief pressor response and a more sustained depressor response. After a perineural treatment …


Norepinephrine Induces Macrophage Polarization Critical To Eliciting Renal Fibrogenesis, Hannah Manoj Jan 2019

Norepinephrine Induces Macrophage Polarization Critical To Eliciting Renal Fibrogenesis, Hannah Manoj

Undergraduate Research Symposium Posters

Renal denervation before ischemic injury has been shown to protect against fibrogenesis and the inflammatory response, which are two causes for the progression of chronic kidney disease. However, the administration of norepinephrine (NE) to denervated renal systems induced fibrogenesis and inflammation after ischemic injury. Our previous data indicates that NE-mediated stimulation of the α2-AR receptors is responsible for regulating several of the processes implicated in fibrogenesis and inflammation, including the accumulation, migration, and infiltration of macrophages to the site of injury; this is especially relevant as macrophages have been implicated as one potential cause for the inflammatory response.

Recent studies, …


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 Jan 2019

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 …


White-Nose Syndrome And Immune Responses In A Resistant Bat Species (Eptesicus Fuscus), Keslie Skye Naffa Jan 2019

White-Nose Syndrome And Immune Responses In A Resistant Bat Species (Eptesicus Fuscus), Keslie Skye Naffa

Graduate Theses/Dissertations

White-nose syndrome (WNS) has had a large negative impact on bat populations across eastern North America since its arrival in 2006. Bats affected by WNS appear to die of starvation, possibly due to the increased arousals during hibernation when there is no food present to replace the energy used to arouse. During hibernation, the bat’s immune system should be suppressed. However, once a bat of a susceptible species is exposed to the fungus that causes WNS, Psuedogymnoascus destructans (Pd), the immune system seems to respond, potentially causing an elevation in metabolic rate, which may cause the bat to …


Behavioral Insights Into Nociceptor Function: A Systematic Approach To Understanding Postsurgical And Neuropathic Pain Mechanisms In Rats, Max Odem Dec 2018

Behavioral Insights Into Nociceptor Function: A Systematic Approach To Understanding Postsurgical And Neuropathic Pain Mechanisms In Rats, Max Odem

Dissertations and Theses (Open Access)

Postsurgical and neuropathic pain are each clinically common, and often associated with ongoing pain. Ongoing pain has been linked to ongoing activity (OA) in human C-fiber nociceptors. Preclinical studies using rodent neuropathic models have concentrated on allodynia driven by OA generated in non-nociceptive Aβ fibers, but little attention has been paid to postsurgical pain in sham controls or to C-fiber nociceptor OA promoting ongoing pain.

Operant assays that reveal negative motivational and cognitive aspects of voluntary pain-related behavior may be particularly sensitive to pain-related alterations. In the mechanical conflict (MC) test, rodents can freely choose to escape from a brightly …


Neutrophil Extracellular Traps And Vascular Barrier Injury, Jamie E. Meegan Oct 2018

Neutrophil Extracellular Traps And Vascular Barrier Injury, Jamie E. Meegan

USF Tampa Graduate Theses and Dissertations

Sepsis is a life-threatening inflammatory condition with high morbidity and mortality rates. Though improvements to diagnosis and management of sepsis have been made, the complexity of the disease process and an incomplete understanding of its endpoint mechanisms have prevented major breakthroughs for early diagnosis and treatment. Representing a common endpoint in a number of inflammatory injuries including sepsis, endothelial barrier dysfunction causes fluid leakage and leukocyte infiltration that leads to tissue damage and multiple organ failure. Therefore, elucidating mechanisms of endothelial barrier regulation is needed to further develop targeted therapies in inflammatory disease.

Sepsis is characterized by a hyperinflammatory response …


Lipopolysaccharide‐Induced Inflammation Does Not Alter Muscle Spindle Afferent Mechanosensation Or Sensory Integration In The Spinal Cord Of Adult Mice, Dasha Zaytseva, Anusha Allawala, Joy Franco, Shea Putnam, Adam Abtahie, Nina Bubalo, Connor Criddle, Tuan Nguyen, Peter Nguyen, Shreejit Padmanabhan, Puneet Sanghera, Martina Bremer, Tzvia Abramson, Katherine A.

Inflammation is known to alter nervous system function, but its effect on muscle spindle afferent mechanosensation and sensory integration in the spinal cord has not been well studied. We tested the hypothesis that systemic inflammation induced by an intraperitoneal injection of the endotoxin lipopolysaccharide (LPS; 7.5 × 105 endotoxin units/kg 18 h before experiment) would alter muscle spindle afferent mechanosensation and spinal cord excitability to Group Ia input in male and female adult C57Bl/6 mice. LPS injection caused a systemic immune response, evidenced by decreased white blood cell, monocyte, and lymphocyte concentrations in the blood, increased blood granulocyte concentration, and …

An Investigation Into Fatigue Management: Effects Of Two Different Loading Protocols On Markers Of Inflammation And The Endocrine Response, Jake Bernards

Electronic Theses and Dissertations

The purposes of this dissertation were to 1) determine the effectiveness of the neutrophillymphocyte ratio (NLR) as an athlete monitoring tool in resistance training and 2) determine if repetition maximum or relative intensity loading scheme is superior in managing fatigue through the hormonal, inflammatory, and performances response throughout a 10-week periodized resistance training program. Results from the dissertation give merit to continued research regarding the use of NLR as a monitoring tool to help determine the degree of recovery. Furthermore, results from this dissertation lead to questioning the effectiveness of using a repetition maximum (RM) loading scheme within a periodized …

The protein Rad interacts with the L-type calcium channel complex to modulate trigger Ca2+ and hence to govern contractility. Reducing Rad levels increases cardiac output. Ablation of Rad also attenuated the inflammatory response following acute myocardial infarction. Future studies to target deletion of Rad in the heart could be conducted to establish a novel treatment paradigm whereby pathologically stressed hearts would be given safe, stable positive inotropic support without arrhythmias and without pathological structural remodeling. Future investigations will also focus on establishing inhibitors of Rad and testing the efficacy of Rad deletion in cardioprotection relative to the time of …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Titanium dioxide nanoparticles (nano-TiO2) are one of the most widely used engineered nanomaterials (ENM). Their ubiquitous inclusion warrants a more thorough understanding of their toxicity, particularly in sensitive populations such as pregnant women and the developing fetus.

The aim of the first study was to determine the most sensitive segments of the vasculature to pulmonary ENM exposure. Macrovascular function was investigated in the thoracic aorta, common femoral artery and 3rd order mesenteric arterioles using wire myography. Microvascular function was assessed in 4th and 5th order mesenteric arterioles via pressure myography. Nano-TiO2 exposure induced impairments …


Impact Of Aerobic Exercise On Monocyte Subset Receptor Expression And Macrophage Polarization, Anson M. Blanks Jan 2018

Impact Of Aerobic Exercise On Monocyte Subset Receptor Expression And Macrophage Polarization, Anson M. Blanks

Theses and Dissertations

Atherosclerotic cardiovascular disease (CVD) is hallmarked by inflammatory immune activation, particularly by the induction of a response by monocytes. Classical (CD14++CD16-) are anti-inflammatory mediators under homeostatic conditions, while intermediate (CD14++CD16+) and non-classical (CD14LowCD16++) monocytes promote inflammation following activation. Monocyte activation and functionality is dependent upon receptor expression and ligand production by a variety of cells, including monocytes. Alterations in the expression of surface receptors often have a direct impact upon monocyte function, such as the increased pro-inflammatory cytokine production in response to activation that accompanies elevated CD14 expression …

Sustained Sensitizing Effects Of Tumor Necrosis Factor Alpha On Sensory Nerves In Lung And Airways, Ruei-Lung Lin, Qihai Gu, Mehdi Khosravi, Lu-Yuan Lee

Physiology Faculty Publications

Tumor necrosis factor alpha (TNFα) plays a significant role in the pathogenesis of airway inflammatory diseases. Inhalation of aerosolized TNFα induced airway hyperresponsiveness accompanied by airway inflammation in healthy human subjects, but the underlying mechanism is not fully understood. We recently reported a series of studies aimed to investigate if TNFα elevates the sensitivity of vagal bronchopulmonary sensory nerves in a mouse model; these studies are summarized in this mini-review. Our results showed that intratracheal instillation of TNFα induced pronounced airway inflammation 24 hours later, as illustrated by infiltration of eosinophils and neutrophils and the release of inflammatory mediators and …


Exogenous Ubiquitin: Role In Myocardial Inflammation And Remodeling Post- Ischemia/Reperfusion Injury, Stephanie Scofield Dec 2017

Exogenous Ubiquitin: Role In Myocardial Inflammation And Remodeling Post- Ischemia/Reperfusion Injury, Stephanie Scofield

Electronic Theses and Dissertations

Sympathetic stimulation occurs in the heart after injuries such as ischemia/reperfusion (I/R) and myocardial infarction and affects myocardial remodeling. Prolonged sympathetic stimulation can result in myocardial dysfunction through its effects on cardiac myocyte apoptosis and myocardial fibrosis. Ubiquitin (UB) is well known for its role of tagging old or damaged proteins for degradation via the UB-proteosome pathway. The role of exogenous UB however, is not fully understood. Previously, our lab showed that β-adrenergic receptor (β-AR) stimulation increased levels of extracellular UB in the conditioned media of adult rat ventricular myocytes and that UB inhibits β-AR-stimulated apoptosis. This study investigates the …

Hypersensitivity Of Vagal Pulmonary Afferents Induced By Tumor Necrosis Factor Alpha In Mice, Ruei-Lung Lin, Qihai Gu, Lu-Yuan Lee

Physiology Faculty Publications

Tumor necrosis factor alpha (TNFα), a pro-inflammatory cytokine, plays a significant role in the pathogenesis of allergic asthma. Inhalation of TNFα also induces airway hyperresponsiveness in healthy human subjects, and the underlying mechanism is not fully understood. A recent study reported that TNFα caused airway inflammation and a sustained elevation of pulmonary chemoreflex responses in mice, suggesting a possible involvement of heightened sensitivity of vagal pulmonary C-fibers. To investigate this possibility, the present study aimed to investigate the effect of a pretreatment with TNFα on the sensitivity of vagal pulmonary afferents in anesthetized mice. After TNFα (10 μg/ml, 0.03 ml) …


Macrophages Are Necessary For Epimorphic Regeneration In African Spiny Mice, Jennifer Simkin, Thomas R. Gawriluk, John C. Gensel, Ashley W. Seifert May 2017

Macrophages Are Necessary For Epimorphic Regeneration In African Spiny Mice, Jennifer Simkin, Thomas R. Gawriluk, John C. Gensel, Ashley W. Seifert

Biology Faculty Publications

How the immune system affects tissue regeneration is not well understood. In this study, we used an emerging mammalian model of epimorphic regeneration, the African spiny mouse, to examine cell-based inflammation and tested the hypothesis that macrophages are necessary for regeneration. By directly comparing inflammatory cell activation in a 4 mm ear injury during regeneration (Acomys cahirinus) and scarring (Mus musculus), we found that both species exhibited an acute inflammatory response, with scarring characterized by stronger myeloperoxidase activity. In contrast, ROS production was stronger and more persistent during regeneration. By depleting macrophages during injury, we demonstrate …

Diabetic Cardiomyopathy: An Immunometabolic Perspective., Paras K. Mishra, Wei Ying, Shyam Sundar Nandi, Gautam K. Bandyopadhyay, Kaushik K. Patel, Sushil K. Mahata

Journal Articles: Cellular & Integrative Physiology

The heart possesses a remarkable inherent capability to adapt itself to a wide array of genetic and extrinsic factors to maintain contractile function. Failure to sustain its compensatory responses results in cardiac dysfunction, leading to cardiomyopathy. Diabetic cardiomyopathy (DCM) is characterized by left ventricular hypertrophy and reduced diastolic function, with or without concurrent systolic dysfunction in the absence of hypertension and coronary artery disease. Changes in substrate metabolism, oxidative stress, endoplasmic reticulum stress, formation of extracellular matrix proteins, and advanced glycation end products constitute the early stage in DCM. These early events are followed by steatosis (accumulation of lipid droplets) …

NYMC Faculty Publications

Cardiac lymphatic vasculature undergoes substantial expansion in response to myocardial infarction (MI). However, there is limited information on the cellular mechanisms mediating post-MI lymphangiogenesis and accompanying fibrosis in the infarcted adult heart. Using a mouse model of permanent coronary artery ligation, we examined spatiotemporal changes in the expression of lymphendothelial and mesenchymal markers in the acutely and chronically infarcted myocardium. We found that at the time of wound granulation, a three-fold increase in the frequency of podoplanin-labeled cells occurred in the infarcted hearts compared to non-operated and sham-operated counterparts. Podoplanin immunoreactivity detected LYVE-1-positive lymphatic vessels, as well as masses of …

The Role Of Pparγ In Placental Development And Disease, Leena Kadam Jan 2017

The Role Of Pparγ In Placental Development And Disease, Leena Kadam

Wayne State University Dissertations

The placenta in mammals forms the maternal fetal interface serving as the source of nutrition for the fetus throughout gestation. It comprises of two major trophoblast lineages: (i) the decidua invading extra-villous trophoblast (EVT) and (ii) the placenta residing villous trophoblast (VT). The EVT’s invade the maternal endometrium to establish pregnancy and secure blood-flow to the implantation site. The VT villous trophoblast forms the main maternal-fetal exchange surface and ensures nutrient and gas exchange to facilitate growth throughout pregnancy. Additionally, both lineages are involved in immunological functions such as maintaining allogenic tolerance and regulation of immune cell activation at the …


The Role Of Human Msc Derived Exosomes In The Treatment Of Periodontal Diseases, Sonia S. Talegaonkar Jan 2017

The Role Of Human Msc Derived Exosomes In The Treatment Of Periodontal Diseases, Sonia S. Talegaonkar

Theses and Dissertations

Periodontal disease affects 47% of Americans over 30. Characterized by microbial dysbiosis and unregulated inflammation, severe periodontitis causes degradation of bone and soft tissue around teeth. Current treatments have limited regenerative outcomes and frequent reinfection by harmful bacteria. Human mesenchymal stem cells (hMSCs) have been shown to promote wound healing and tissue regeneration. Many therapeutic benefits of hMSCs are due to their secretome products, like exosomes. Our long-term goal is to develop periodontal therapies with hMSC exosomes. The objectives of this study were to determine the effect of hMSC-derived exosomes on cellular activity of hMSCs and investigate whether hMSC exosome …


Inflammatory Gene Expression In Women Diagnosed With Polycystic Ovarian Syndrome, Myles K. Taylor Dec 2016

Inflammatory Gene Expression In Women Diagnosed With Polycystic Ovarian Syndrome, Myles K. Taylor

Electronic Theses & Dissertations

Polycystic ovarian syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The pathophysiology of PCOS has conventionally thought to originate from androgen excess. However, recent evidence suggests that androgen excess is a downstream consequence to inflammatory dysregulation and subsequent metabolic abnormalities. Inflammatory mRNA gene expression of TNFa and IL-1ß in mononuclear cells isolated from women diagnosed with PCOS was explored using qPCR. Additionally, the correlations between body mass index (BMI) and fasting glucose on mRNA expression of TNFa and IL-1ß were explored. mRNA expression of both TNFa and IL-1ß were found to be significantly higher in PCOS …


Extracellular Matrix Remodeling And The Inflammatory Response During Skeletal Muscle Regeneration In Sarcopenic Obese Mice, Lemuel Arthur Brown Dec 2016

Extracellular Matrix Remodeling And The Inflammatory Response During Skeletal Muscle Regeneration In Sarcopenic Obese Mice, Lemuel Arthur Brown

Graduate Theses and Dissertations

AIM: Sarocpenic obesity is a national concern within the United States because this metabolic syndrome is tied with reduced mobility and quality of life. Both obesity and aging are associated with insulin-resistance, chronic low-grade inflammation and muscle weakness. Skeletal muscle regeneration is a process that involves the coordinated effort of myogenic regulatory factors (MRFs), inflammatory signaling, and extracellular matrix (ECM) remodeling for optimal regeneration. It has been demonstrated that obesity and aging have a reduction in muscle regeneration. It has not been examined if sarcopenic obesity will further reduce muscle mass and the regenerative process. The purpose of this study …


Cardiovascular And Hematopoietic Responses To Volatile Benzene Exposure., Wesley Tyler Abplanalp Aug 2016

Cardiovascular And Hematopoietic Responses To Volatile Benzene Exposure., Wesley Tyler Abplanalp

Electronic Theses and Dissertations

The rapid and recent increase in the global epidemic of diabetes and cardiovascular disease suggests a strong component of the environment is contributing. Benzene is a ubiquitous volatile pollutant generated by cigarette smoke, automobile exhaust, wildfires and industrial activities. Consequently, it is found in almost all urban and rural air samples. Benzene is known to cause hematotoxicity and its metabolism generates oxidative stress. Although, benzene has been studied for many years, few investigations have probed what influence benzene exposure may have on other physiological processes. Here we hypothesize that benzene metabolism by hepatic-CYP450 2E1 generates oxidative stress and inflammation, which …

Background: Nociceptive and neuropathic pain occurs as part of the disease process after traumatic brain injury (TBI) in humans. Central and peripheral inflammation, a major secondary injury process initiated by the traumatic brain injury event, has been implicated in the potentiation of peripheral nociceptive pain. We hypothesized that the inflammatory response to diffuse traumatic brain injury potentiates persistent pain through prolonged immune dysregulation.

Results: To test this, adult, male C57BL/6 mice were subjected to midline fluid percussion brain injury or to sham procedure. One cohort of mice was analyzed for inflammation-related cytokine levels in cortical biopsies and serum along an …
