Distinction Of The Memory B Cell Response To Cognate Antigen Versus Bystander Inflammatory Signals, Micah J. Benson, Raul Elgueta, William Schpero, Michael Molloy, Weijun Zhang, Edward Usherwood, Randolph J. Noelle
Distinction Of The Memory B Cell Response To Cognate Antigen Versus Bystander Inflammatory Signals, Micah J. Benson, Raul Elgueta, William Schpero, Michael Molloy, Weijun Zhang, Edward Usherwood, Randolph J. Noelle
Dartmouth Scholarship
The hypothesis that bystander inflammatory signals promote memory B cell (BMEM) self- renewal and differentiation in an antigen-independent manner is critically evaluated herein. To comprehensively address this hypothesis, a detailed analysis is presented examining the response profiles of B-2 lineage B220 + IgG + BMEM toward cognate protein antigen in comparison to bystander inflammatory signals. After in vivo antigen encounter, quiescent BMEM clonally expand. Surprisingly, proliferating BMEM do not acquire germinal center (GC) B cell markers before generating daughter BMEM and differentiating into plasma cells or form structurally identifiable GCs. In striking contrast to …
Didox Modulates Reactive Oxygen Species Production And Inflammatory Events Induced By Lipopolysaccharide (Lps) And Aryl Hydrocarbon Receptor (Ahr) Ligands In Raw 264.7 Murine Macrophages., Thabe Matsebatlela
All Dissertations
Aberrant activation of macrophages during inflammation results in oxidative burst release of reactive oxygen and reactive nitrogen species (ROS/RNS) which are widely accepted to participate in pathogenesis of cancer, cardiovascular disease, atherosclerosis, hypertension, ischemia/reperfusion injury, diabetes mellitus, neurodegenerative diseases (Alzheimer's disease and Parkinson's disease), rheumatoid arthritis, and ageing. It is demonstrated here that Didox (3,4-Dihydroxybenzohydroxamic acid) possesses antioxidative and anti-inflammatory properties that can protect against inflammation and oxidative stress induced by lipopolysaccharide (LPS) and aryl hydrocarbon receptor (AHR) ligands (PCB126, E804, and IO) in Raw 264.7 murine macrophages. In brief, it is demonstrated here that Didox inhibits LPS-induced oxidative stress, …
Dicer Is Required For Female Reproductive Tract Development And Fertility In The Mouse., Gabriel Gonzalez, Richard R Behringer
Dicer Is Required For Female Reproductive Tract Development And Fertility In The Mouse., Gabriel Gonzalez, Richard R Behringer
Journal Articles
Dicer encodes a riboendonuclease required for microRNA biosynthesis. Dicer was inactivated in Müllerian duct mesenchyme-derived tissues of the reproductive tract of the mouse, using an Amhr2-Cre allele. Although Amhr2-Cre; Dicer conditional mutant males appeared normal and were fertile, mutant females were infertile. In adult mutant females, there was a reduction in the size of the oviducts and uterine horns. The oviducts were less coiled compared to controls and cysts formed at the isthmus near the uterotubal junction. Unfertilized, degenerate oocytes were commonly found within these cysts, indicating a defect in embryo transit. Beads transferred into the mutant oviduct failed to …

Chronic Exposure To Arsenic In The Drinking Water Alters The Expression Of Immune Response Genes In Mouse Lung, Courtney D. Kozul, Thomas H. Hampton, Jennifer C. Davey, Julie A. Gosse, Athena P. Nomikos, Phillip L. Eisenhauer, Daniel J. Weiss, Jessica E. Thorpe, Michael A. Ihnat, Joshua W. Hamilton
Dartmouth Scholarship
Background:
Chronic exposure to drinking water arsenic is a significant worldwide environmental health concern. Exposure to As is associated with an increased risk of lung disease, which may make it a unique toxicant, because lung toxicity is usually associated with inhalation rather than ingestion.
Objectives:
The goal of this study was to examine mRNA and protein expression changes in the lungs of mice exposed chronically to environmentally relevant concentrations of As in the food or drinking water, specifically examining the hypothesis that As may preferentially affect gene and protein expression related to immune function as part of its mechanism of …

Investigations suggest a protective role of n-3 polyunsaturated fatty acids (PUFA) but opposing roles of n-6 PUFA in inflammation, but the effects in vivo the human are not clear. We therefore tested the hypothesis that higher intakes of n-3 PUFA and n-6 PUFA are associated with lower levels of inflammation among a population consuming a diet high in PUFA. This study aimed to assess theassociation between PUFA intake and serum C-reactive protein (CRP) concentrations in a group of Japanese employees. The study subjects were 300 men and 211 women aged 21 to 67 years workingin 2 municipal offices of Japan. …
Cannabinoid Receptor Type 2 Activation Induces A Microglial Anti-Inflammatory Phenotype And Reduces Migration Via Mkp Induction And Erk Dephosphorylation, Edgar A. Romero-Sandoval, Ryan Horvath, Russell P. Landry, Joyce A. Deleo
Cannabinoid Receptor Type 2 Activation Induces A Microglial Anti-Inflammatory Phenotype And Reduces Migration Via Mkp Induction And Erk Dephosphorylation, Edgar A. Romero-Sandoval, Ryan Horvath, Russell P. Landry, Joyce A. Deleo
Dartmouth Scholarship
Cannabinoid receptor type 2 (CBR2) inhibits microglial reactivity through a molecular mechanism yet to be elucidated. We hypothesized that CBR2 activation induces an anti-inflammatory phenotype in microglia by inhibiting extracellular signal-regulated kinase (ERK) pathway, via mitogen-activated protein kinase-phosphatase (MKP) induction. MKPs regulate mitogen activated protein kinases, but their role in the modulation of microglial phenotype is not fully understood.

BACKGROUND: Sporadic Parkinson's disease (PD) is a progressive neurodegenerative disorder with unknown cause, but it has been suggested that neuroinflammation may play a role in pathogenesis of the disease. Neuroinflammatory component in process of PD neurodegeneration was proposed by postmortem, epidemiological and animal model studies. However, it remains unclear how neuroinflammatory factors contribute to dopaminergic neuronal death in PD.
FINDINGS: In this study, we analyzed the relationship among inducible nitric oxide synthase (iNOS)-derived NO, mitochondrial dysfunction and dopaminergic neurodegeneration to examine the possibility that microglial neuroinflammation may induce dopaminergic neuronal loss in the substantia nigra. Unilateral injection of lipopolysaccharide (LPS) …
The Role Of Inflammation In The Early Radiation Response, Christy Marie Wilson
The Role Of Inflammation In The Early Radiation Response, Christy Marie Wilson
Theses and Dissertations (ETD)
Radiation is one of the principal treatments for adults and children with brain tumors, and is one of the oldest established treatments for tumors of all types. Currently, the limiting factor for the use of radiation is the effect on normal tissue adjacent to the tumor. Toxicity, including early and late effects from radiation, limits the dose administered to the tumor and reduces the probability of cure. This work has three aims in its attempt to understand and limit early radiation damage: characterize the role of the inflammatory molecules tumor necrosis factor alpha (TNF) and intracellular adhesion molecule-1 (ICAM-1) in …
Immunomodulatory Effects Of Novel Therapies For Stroke, Aaron A. Hall
Immunomodulatory Effects Of Novel Therapies For Stroke, Aaron A. Hall
USF Tampa Graduate Theses and Dissertations
Each year, approximately 795,000 people suffer a new or recurrent stroke. About 610,000 of these are first attacks, and 185,000 are recurrent attacks (Carandang et al. 2006). Currently the only FDA approved treatment for ischemic stroke is recombinant tissue plasminogen activator (Alteplase) (Marler and Goldstein 2003). Unfortunately its use is restricted to a short, 4.5 hour, time window. Two promising therapies in the treatment of stroke at delayed timepoints are human umbilical cord blood cells (HUCBC) and the sigma receptor agonist DTG
The first series of experiments were conducted to characterize the effects of sigma receptors on various aspects of …
Immediate Effect Of Heel-Pain Orthosis And An Augmented Low-Dye Taping On Plantar Pressures And Pain In Subjects With Plantar Fasciitis, Tracy Andus
Human Movement Sciences & Special Education Theses & Dissertations
Research has been done investigating plantar pressures and pain in subjects with pathologies after the application of orthoses and arch taping. To date, however, no study has been conducted investigating plantar pressures and pain in subjects with plantar fasciitis after the application of the augmented low-dye taping (ALD) in comparison to a heel-pain orthosis (HPO). Therefore, the purpose of this study was to determine the effects of the ALD in comparison to a HPO on pain, peak plantar pressure (PPP), and mean plantar pressure (MPP) under multiple areas of the foot in subjects with plantar fasciitis while walking and jogging. …

Department of Radiation Oncology Faculty Papers
This article discusses the current techniques and future directions of infection imaging with particular attention to respiratory, central nervous system, abdominal, and postoperative infections. The agents currently in use localize to areas of infection and inflammation. An infection-specific imaging agent would greatly improve the utility of scintigraphy in imaging occult infections. The superior spatial resolution of (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG-PET) and its lack of reliance on a functional immune system, gives this agent certain advantages over the other radiopharmaceuticals. In respiratory tract infection imaging, an important advancement would be the ability to quantitatively delineate lung inflammation, allowing one to …

Illawarra Health and Medical Research Institute
The use of “omics” techniques in combination with model systems and molecular tools allows to understand how foods and food components act on metabolic pathways to regulate transcriptional processes. Polyunsaturated fatty acids have distinctive nutritional and metabolic effects because they give rise to lipid mediated products and affect the expression of various genes involved in intestinal inflammation. The present review focuses on the molecular effects of dietary polyunsaturated fatty acids on intestinal inflammation
The Effect Of Zinc On Cytokine Release And Signal Transduction In Airway Epithelial Cells, Nai-Lin Cheng
The Effect Of Zinc On Cytokine Release And Signal Transduction In Airway Epithelial Cells, Nai-Lin Cheng
All ETDs from UAB
Zinc is an essential cation for life that is involved in numerous physiology and pathophysiology processes. Despite its wide use as a cytoprotective agent in medications, its cellular and molecular mechanisms of action have not been well established. In order to define the potential therapeutic benefit of zinc, I used several Cystic Fibrosis (CF) and non-CF human airway epithelial cell lines as models in my studies. Extracellular zinc caused release calcium from the endoplasmic reticulum though zinc-sensitive Gq-coupled receptor(s) that may subsequently modulate ion channels. In addition, zinc also exhibited anti-inflammatory effects. Zinc inhibited pro-inflammatory molecular TNFα-induced cytokine and chemokine …

Turkish Journal of Medical Sciences
Aims: It is known that there is a relationship between diabetic complications and chronic inflammation characterized by alterations in circulating acute phase proteins. It has been emphasized that inflammation contributes to diabetic complications and that gliclazide -an antidiabetic sulfonylurea - decreases the development of such complications. In this study, we aimed to investigate whether gliclazide or diet treatment has an effect on serum levels of acute phase reactants, markers of inflammation. Materials and Methods: Fifty-six newly diagnosed patients with type 2 diabetes and 30 clinically healthy subjects were evaluated prospectively. Twenty-six patients were treated with proper diet and daily gliclazide …

Protective Mechanisms Of Apoa-I Mimetic Peptide Action In Sepsis-Induced Tissue Injury, Zhenghao Zhang
Protective Mechanisms Of Apoa-I Mimetic Peptide Action In Sepsis-Induced Tissue Injury, Zhenghao Zhang
All ETDs from UAB
Sepsis is among the top ten causes of death in the US, and it is associated with severe inflammatory tissue damage and organ dysfunction. Reduced plasma high density lipoprotein (HDL) is associated with increased mortality in septic patients. Since raising plasma apolipoprotein (apo) A-I and HDL may reduce sepsis complications, we tested the hypothesis that the apoA-I mimetic peptide 4F confers similar protective effects in two animal models of sepsis, and explored the possible mechanisms. In endotoxemic rats, inflammatory mediators were significantly induced while blood pressure was significantly reduced by 6hr. The impaired arterial response to vasoconstrictors was related to …
