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 …

Nanomedicine-Driven Neuropathic Pain Relief In Rat Model Is Associated With Macrophage Polarity And Mast Cell Activation, Muzamil Saleem

Electronic Theses and Dissertations

We explored the immune neuropathology underlying multi-day relief from neuropathic pain in a rat model initiated at the sciatic nerve by using a nanoemulsion-based nanomedicine as a biological probe. The nanomedicine is theranostic: both therapeutic (containing celecoxib drug) and diagnostic (containing near-infrared fluorescent (NIRF) dye) and is small enough to be phagocytosed by circulating monocytes. A model of neuropathic pain is initiated by tying four 1mm spaced knots around the sciatic nerve with chromic gut suture, which results in neuroinflammation, and a resultant pain-like behavior manifests. We show that pain-like behavior reaches a plateau of maximum hypersensitivity 8 days post-surgery, …

The Histone Deacetylase Inhibitor Tubacin Mitigates Endothelial Dysfunction By Up-Regulating The Expression Of Endothelial Nitric Oxide Synthase., Jihui Chen, Jian Zhang, Noor F. Shaik, Bing Yi, Xin Wei, Xiao-Feng Yang, Ulhas P. Naik, Ross Summer, Guijun Yan, Xinyun Xu, Jianxin Sun

Center for Translational Medicine Faculty Papers

Endothelial nitric oxide (NO) synthase (eNOS) plays a critical role in the maintenance of blood vessel homeostasis. Recent findings suggest that cytoskeletal dynamics play an essential role in regulating eNOS expression and activation. Here, we sought to test whether modulation of cytoskeletal dynamics through pharmacological regulation of histone deacetylase 6 (HDAC6)-mediated tubulin deacetylation affects eNOS expression and endothelial function in vitro and in vivo.Wefound that tubulin acetylation inducer (tubacin), a compound that appears to selectively inhibit HDAC6 activity, dramatically increased eNOS expression in several different endothelial cell lines, as determined by both immunoblotting and NO production assays. Mechanistically, we found …

Role Of Microbiome In Impacting Treatment Of Obesity And Type 2 Diabetes, Aneseh Adeshirlarijaney

Biology Dissertations

Metabolic Syndrome is a constellation of metabolic abnormalities associated with insulin resistance and obesity, including hyperglycemia and hypertension. Metabolic syndrome often progresses to type 2 diabetes, hypertension, cardiovascular disease, and liver disease. Metabolic syndrome is increasingly appreciated to be an inflammatory disease in that is associated with increased expression of pro-inflammatory genes and markers, remodeling of adipose tissue, and markedly increased incidence in the last 50 years. Additionally, both diseases alter the microbiota, specifically with alteration in gut microbiota composition. Metabolic syndrome requires a microbiota in that disease is not observed in germ- free mice, and some aspects of the …

Distinct Roles Of Interferon Alpha And Beta In Controlling Chikungunya Virus Replication And Modulating Neutrophil-Mediated Inflammation, Lindsey E Cook, Marissa C Locke, Alissa R Young, Kristen Monte, Matthew L Hedberg, Raeann M Shimak, Kathleen C F Sheehan, Deborah J Veis, Michael S Diamond, Deborah J Lenschow

Open Access Publications

Type I interferons (IFNs) are key mediators of the innate immune response. Although members of this family of cytokines signal through a single shared receptor, biochemical and functional variation exists in response to different IFN subtypes. While previous work has demonstrated that type I IFNs are essential to control infection by chikungunya virus (CHIKV), a globally emerging alphavirus, the contributions of individual IFN subtypes remain undefined. To address this question, we evaluated CHIKV pathogenesis in mice lacking IFN-β (IFN-β knockout [IFN-β-KO] mice or mice treated with an IFN-β-blocking antibody) or IFN-α (IFN regulatory factor 7 knockout [IRF7-KO] mice or mice …

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 …

Inflammation, mitochondrial dysfunction, stress and depression are common pathologies associated with these chronic diseases. Many individuals engage in yoga because they believe it will improve their health. However, research examining the impact of yoga on markers of health associated with chronic diseases is limited and often reports conflicting results. Therefore, the purpose of this dissertation is to examine the relationship between yoga and inflammation, protein content of oxidative phosphorylation complexes, stress and depression, which may support the use of lifestyle …

Inflammation And Corrosion In Total Hip Prostheses: The Generation And Interaction Of Reactive Oxygen Species With Cocrmo Metallic Biomaterial Surfaces, Michael John Wiegand

All Dissertations

There are many molecules, species and mechanisms that contribute to the overall wear and degradation of biometallic alloys like cobalt-chromium-molybdenum (CoCrMo). Following implantation, orthopaedic alloys are subject to an encompassing inflammatory response that will either lead to foreign body giant cell formation and attachment to the surface or the fibrous tissue encapsulation, forming an inflamed periprosthetic joint. In addition to the inflammatory response, tribocorrosion-based processes of alloy-on-alloy or alloy-on-polymer couples release polymeric wear debris, oxides, hydroxides, and metal ions in response to excessive wear, loading and corrosion. It is hypothesized that these processes, biological and triboelectrochemical, are linked together in …

The Effects Of Indirubin Derivative E804 On Inflammatory Profiles In Glioblastoma Multiforme Cell Lines And Subsequent Crosstalk Effect On Tumor Associated Thp-1 Macrophages, Micaela Ro Scobie

All Dissertations

Glioblastoma Multiforme (GBM) is a highly invasive brain tumor that affects approximately 18,000 people annually in the USA alone yet remains without curative treatment. Median survival with treatment is 14 months, with most treatments only prolonging life for several months while causing severe adverse side effects. There is a need for new therapeutic modalities. Herein I explore two small molecules that show promise in modulating inflammatory signaling in an in vitro GBM model. Indirubins E804 (indirubin-3’-(2,3 dihydroxypropyl)-oximether) and 7BIO (7-Bromoindirubin-3’-oxime) are synthetic derivatives of natural indirubin. Natural indirubin is a bisindole alkaloid derived from tryptophan precursors and is an agonist …

Anti-Inflammatory Effects Of Cruciferous And Apiaceous Vegetables In C57bl/6j Mice Colon, Rosa Moreno Narvaez

Graduate Theses and Dissertations

Previous studies have demonstrated chemo-preventive potential of cruciferous and apiaceous vegetables against colon cancer. Colon inflammation is one condition closely related with colon cancer initiation. Therefore, we wanted to compare if total western diet (TWD) was as pro-inflammatory as died-induced obesity (DIO) and a better dietary model for human conditions, and determine if diet supplementation with cruciferous (broccoli, watercress and cabbage) or apiaceous vegetables (celery and parsnip) could reduce dietary inflammation, and which vegetable was more effective.

It's A Hard Nacht Life: Understanding How Nlrp12 Ticks, Abbigale Julia Brown

MSU Graduate Theses

The protein NOD- like receptor pyrin domain containing 12 (NLRP12) comes from a family of protein receptors with a wide range of functions including fertility as well as anti-inflammatory properties. The biological role of NLRP12 is poorly understood: research on the mechanisms behind its function and/or activation remains contradictory between different cell models. Current research suggests its involvement in a multi-protein complex named the inflammasome. The alternative hypothesis that has also been proposed is that NLRP12 is not a part of the inflammasome, rather it negatively regulates a transcription factor known as NF-��B down stream of Toll-like receptors. NLRP12 is …

Effects Of A 12-Week Vigorous Interval Training Intervention On Pro-Inflammatory Markers In Post-Operative Bariatric And Obese Participants, Brittany Rood

Masters Theses, 2010-2019

Increase prevalence of cardiovascular and other chronic diseases linked to inflammation has led to research on pro-inflammatory cytokines, like tumor necrosis factor - alpha (TNF-α) and lipoprotein-associated phospholipase A₂ (Lp-PLA₂), in attempt to define the relationship between chronic disease, inflammation, and obesity. PURPOSE: Examine the effect of twelve weeks of vigorous intensity interval training on pro-inflammatory markers in post-operative bariatric and obese participants. METHODS: 9 post-operative bariatric individuals [1 man, 8 women; Body mass index (BMI) = 34.23 ± 2.54 kg/m²], 12 obese individuals [5 men, 7 women; BMI=35.77 ± 1.67 kg/m^{2 …}

Sustained inflammation and matrix metalloproteinase (MMP) activation contribute to vascular occlusive/proliferative disorders. Interleukin-17 (IL-17) is a proinflammatory cytokine that signals mainly via TRAF3 Interacting Protein 2 (TRAF3IP2), an upstream regulator of various critical transcription factors, including AP-1 and NF-κB. Reversion inducing cysteine rich protein with kazal motifs (RECK) is a membrane-anchored MMP inhibitor. Here we investigated whether IL-17A/TRAF3IP2 signaling promotes MMP-13-dependent human aortic smooth muscle cell (SMC) proliferation and migration, and determined whether RECK overexpression blunts these responses. Indeed, IL-17A treatment induced (a) JNK, p38 MAPK, AP-1, NF-κB, and CREB activation, (b) miR-21 induction, (c) miR-27b and miR-320 inhibition, (d) …

Dexamethasone As Abortive Treatment For Refractory Seizures Or Status Epilepticus In The Inpatient Setting, Alexander B. Ramos, Roberto A. Cruz, Nicole R. Villemarette-Pittman, Piotr W. Olejniczak, Edward C. Mader Jr.

School of Medicine Publications and Presentations

Refractory seizures or status epilepticus (RS/SE) continues to be a challenge in the inpatient setting. Failure to abort a seizure with antiepileptic drugs (AEDs) may lead to intubation and treatment with general anesthesia exposing patients to complications, extending hospitalization, and increasing the cost of care. Studies have shown a key role of inflammatory mediators in seizure generation and termination. We describe 4 patients with RS/SE that was aborted when dexamethasone was added to conventional AEDs: a 61-year-old female with temporal lobe epilepsy who presented with delirium, nonconvulsive status epilepticus, and oculomyoclonic status; a 56-year-old female with history of traumatic left …

Baseline And Stress-Induced Cognitive Control Deficits And Pro-Inflammatory Cytokines In Currently, Remitted, And Never Depressed Individuals, Katerina Rnic

Electronic Thesis and Dissertation Repository

Background: Cognitive theories posit that cognitive control deficits promote depression by reducing ability to self-regulate under stress. When activated by stress and accessible to working memory, negative cognitive content and structure (i.e., schemas), may interfere with cognitive control abilities, resulting in even greater declines in executive functioning. Moreover, burgeoning evidence indicates that social stress upregulates inflammation, resulting in a pro-inflammatory phenotype that drives depression pathogenesis. However, cognitive mechanisms underlying this process are not well understood. An objective of this study was to examine depression-related deficits in cognitive control and their association with poor self-regulation. Another purpose was to evaluate the …

Ischemic strokes are categorized by permanent or transient obstruction of blood flow, which impedes delivery of oxygen and essential nutrients to brain. In the last decade, the therapeutic window for tPA has increased from 3 to 5–6 h, and a new technique, involving the mechanical removal of the clot (endovascular thrombectomy) to allow reperfusion of the injured area, is being used more often. This last therapeutic approach can be done until 24 h after stroke onset. Due to this fact, more acute …

Faculty Publications

Gulf War illness (GWI) is characterized by the persistence of inflammatory bowel disease, chronic fatigue, neuroinflammation, headache, cognitive impairment, and other medically unexplained conditions. Results using a murine model show that enteric viral populations especially bacteriophages were altered in GWI. The increased viral richness and alpha diversity correlated positively with gut bacterial dysbiosis and proinflammatory cytokines. Altered virome signature in GWI mice also had a concomitant weakening of intestinal epithelial tight junctions with a significant increase in Claudin-2 protein expression and decrease in ZO1 and Occludin mRNA expression. The altered virome signature in GWI, decreased tight junction protein level was …

Advanced Glycation End Products: Formation, Role In Diabetic Complications, And Potential In Clinical Application, Rujman Khan, Xin Yee Ooi, Matthew N. Parvus, Laura Valdez, Andrew Tsin

School of Medicine Publications and Presentations

Hyperglycemic conditions and disruptions to glucose-regulating pathways lead to increased formation of highly reactive aldehydes, methylglyoxal and glyoxal, which react with certain arginine and lysine residues in proteins to form advanced glycation end products (AGEs). These AGEs damage the integrity of the retinal vasculature predominantly through two mechanisms: non-receptor-mediated damage, which pertains to the interaction with extracellular matrix and its functional properties, and receptor-mediated damage through AGE interactions with their receptors (RAGE) on pericytes and Muller cells. Damage occurring between AGE and RAGE potentially generates reactive oxygen species, inflammatory cytokines, and growth factors. Both mechanisms result in increased permeability of …
