Taking The Perspective That A Depressive State Reflects Inflammation: Implications For The Use Of Antidepressants, Jill Littrell

jill l littrell Dr.

This paper reviews both the evidence that supports the characterization of depression as an inflammatory disorder and the different biochemical mechanisms that have been postulated for the connection between inflammation and depression. This association offers credible explanation for the short term efficacy of antidepressants, which have short term anti-inflammatory effects. Evidence for those anti-inflammatory effects is discussed. Evidence of the contrary long-term effects of antidepressants, which increase rather than decrease inflammation, is also reviewed. It is argued that this increase in inflammation would predict an increase in chronicity among depressed patients that have been treated with antidepressants drugs, which has …

Mcp-1 In Colorectal Cancer: Benefits Of Exercise, Jamie Lee Mcclellan

Theses and Dissertations

The etiology of colon cancer is a complex phenomenon that involves both genetic and environmental factors. However, only about 20% have a familial basis with the largest fraction being attributed to environmental causes that can lead to chronic inflammation. Tumors associated macrophages drive the pro-inflammatory response in the tumor micro-environment and are associated with poor prognosis in certain cancers. Monocyte chemoattractant protein 1 (MCP-1) is thought to be the most important chemokine for recruitment of macrophages to the tumor microenvironment. In chapter 1, we examined the timing and magnitude of the intestinal inflammatory cytokine response in relation to tumorigenesis in …

Factors Of Inflammation In Haitian Americans And African Americans With And Without Type 2 Diabetes, Janet Antwi

FIU Electronic Theses and Dissertations

Chronic low-grade inflammation has been implicated in the processes leading to the development of type 2 diabetes (T2D) and its progression. Non-Hispanic Blacks bear a disproportionate burden of T2D and are highly susceptible to inflammation. This cross-sectional study assessed and compared the serum levels of established adipocytokines; interleukin-6 (IL-6), C-reactive protein (CRP), leptin, and novel adipocytokines; chemerin and omentin in Haitian and African Americans with and without T2D. The relationships of these adipocytokines with metabolic syndrome (MetS), anthropometric and HOMA2 measures by ethnicity and diabetes status were also assessed. Serum levels of IL-6, CRP, leptin, chemerin and omentin were determined …

Nerve Growth Factor Regulates Neurolymphatic Remodeling During Corneal Inflammation And Resolution., Darci M. Fink, Alicia L. Connor, Philip M. Kelley, Maria M. Steele, Michael A. Hollingsworth, Richard M. Tempero

Journal Articles: Eppley Institute

The cellular and physiologic mechanisms that regulate the resolution of inflammation remain poorly defined despite their widespread importance in improving inflammatory disease outcomes. We studied the resolution of two cardinal signs of inflammation-pain and swelling-by investigating molecular mechanisms that regulate neural and lymphatic vessel remodeling during the resolution of corneal inflammation. A mouse model of corneal inflammation and wound recovery was developed to study this process in vivo. Administration of nerve growth factor (NGF) increased pain sensation and inhibited neural remodeling and lymphatic vessel regression processes during wound recovery. A complementary in vivo approach, the corneal micropocket assay, revealed that …

Caspase-3 Mediates The Pathogenic Effect Of Yersinia Pestis Yopm In Liver Of C57bl/6 Mice And Contributes To Yopm's Function In Spleen, Zhan Ye, Amanda A. Gorman, Annette M. Uittenbogaard, Tanya Myers-Morales, Alan M. Kaplan, Donald A. Cohen, Susan C. Straley

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The virulence protein YopM of the plague bacterium Yersinia pestis has different dominant effects in liver and spleen. Previous studies focused on spleen, where YopM inhibits accumulation of inflammatory dendritic cells. In the present study we focused on liver, where PMN function may be directly undermined by YopM without changes in inflammatory cell numbers in the initial days of infection, and foci of inflammation are easily identified. Mice were infected with parent and ΔyopM-1 Y. pestis KIM5, and effects of YopM were assessed by immunohistochemistry and determinations of bacterial viable numbers in organs. The bacteria were found …

Chronic Alcohol-Induced Microrna-155 Contributes To Neuroinflammation In A Tlr4-Dependent Manner In Mice, Dora Lippai, Shashi Bala, Timea Csak, Evelyn A. Kurt-Jones, Gyongyi Szabo

Gyongyi Szabo

INTRODUCTION: Alcohol-induced neuroinflammation is mediated by pro-inflammatory cytokines and chemokines including tumor necrosis factor-alpha (TNFalpha), monocyte chemotactic protein-1 (MCP1) and interleukin-1-beta (IL-1beta). Toll-like receptor-4 (TLR4) pathway induced nuclear factor-kappaB (NF-kappaB) activation is involved in the pathogenesis of alcohol-induced neuroinflammation. Inflammation is a highly regulated process. Recent studies suggest that microRNAs (miRNAs) play crucial role in fine tuning gene expression and miR-155 is a major regulator of inflammation in immune cells after TLR stimulation. AIM: To evaluate the role of miR-155 in the pathogenesis of alcohol-induced neuroinflammation. METHODS: Wild type (WT), miR-155- and TLR4-knockout (KO) mice received 5% ethanol-containing or isocaloric …

Myeloid Derived Hypoxia Inducible Factor 1-Alpha Is Required For Protection Against Pulmonary Aspergillus Fumigatus Infection, Kelly M. Shepardson, Anupam Jhingran, Alayna Caffrey, Joshua J. Obar, Benjamin T. Suratt, Brent L. Berwin, Tobias M. Hohl, Robert A. Cramer

Dartmouth Scholarship

Hypoxia inducible factor 1α (HIF1α) is the mammalian transcriptional factor that controls metabolism, survival, and innate immunity in response to inflammation and low oxygen. Previous work established that generation of hypoxic microenvironments occurs within the lung during infection with the human fungal pathogen Aspergillus fumigatus. Here we demonstrate that A. fumigatus stabilizes HIF1α protein early after pulmonary challenge that is inhibited by treatment of mice with the steroid triamcinolone. Utilizing myeloid deficient HIF1α mice, we observed that HIF1α is required for survival and fungal clearance early following pulmonary challenge with A. fumigatus. Unlike previously reported research with bacterial …

Pharmacotherapy For Uveitis: Current Management And Emerging Therapy., Robert J. Barry, Quan Dong Nguyen, Richard W. Lee, Philip I. Murray, Alastair K. Denniston

Journal Articles: Ophthalmology

Uveitis, a group of conditions characterized by intraocular inflammation, is a major cause of sight loss in the working population. Most uveitis seen in Western countries is noninfectious and appears to be autoimmune or autoinflammatory in nature, requiring treatment with immunosuppressive and/or anti-inflammatory drugs. In this educational review, we outline the ideal characteristics of drugs for uveitis and review the data to support the use of current and emerging therapies in this context. It is crucial that we continue to develop new therapies for use in uveitis that aim to suppress disease activity, prevent accumulation of damage, and preserve visual …

Calcineurin And Glial Signaling: Neuroinflammation And Beyond, Jennifer L. Furman, Christopher M. Norris

Sanders-Brown Center on Aging Faculty Publications

Similar to peripheral immune/inflammatory cells, neuroglial cells appear to rely on calcineurin (CN) signaling pathways to regulate cytokine production and cellular activation. Several studies suggest that harmful immune/inflammatory responses may be the most impactful consequence of aberrant CN activity in glial cells. However, newly identified roles for CN in glutamate uptake, gap junction regulation, Ca²⁺ dyshomeostasis, and amyloid production suggest that CN's influence in glia may extend well beyond neuroinflammation. The following review will discuss the various actions of CN in glial cells, with particular emphasis on astrocytes, and consider the implications for neurologic dysfunction arising with aging, injury, …

A Double-Blind Randomized Trial Of Fish Oil To Lower Triglycerides And Improve Cardiometabolic Risk In Adolescents., Samuel S. Gidding, Carol Prospero, Jobayer Hossain, Frances Zappalla, Prabhakaran Babu Balagopal, Bonita Falkner, Peter Kwiterovich

Department of Pediatrics Faculty Papers

OBJECTIVES: To determine the efficacy of 4 g/day fish oil to lower triglycerides and impact lipoprotein particles, inflammation, insulin resistance, coagulation, and thrombosis.

STUDY DESIGN: Participants (n = 42, age 14 ± 2 years) with hypertriglyceridemia and low-density lipoprotein (LDL) cholesterol/dL were enrolled in a randomized, double-blind, crossover trial comparing 4 g of fish oil daily with placebo. Treatment interval was 8 weeks with a 4-week washout.

RESULTS: Baseline lipid profile was total cholesterol 194 (5.4) mg/dL (mean …

Neuroinflammation And Neurologic Deficits In Diabetes Linked To Brain Accumulation Of Amylin, Sarah Srodulski, Savita Sharma, Adam B. Bachstetter, Jennifer M. Brelsfoard, Conrado Pascual, Xinmin Simon Xie, Kathryn E. Saatman, Linda J. Van Eldik, Florin Despa

Pharmacology and Nutritional Sciences Faculty Publications

BACKGROUND: We recently found that brain tissue from patients with type-2 diabetes (T2D) and cognitive impairment contains deposits of amylin, an amyloidogenic hormone synthesized and co-secreted with insulin by pancreatic β-cells. Amylin deposition is promoted by chronic hypersecretion of amylin (hyperamylinemia), which is common in humans with obesity or pre-diabetic insulin resistance. Human amylin oligomerizes quickly when oversecreted, which is toxic, induces inflammation in pancreatic islets and contributes to the development of T2D. Here, we tested the hypothesis that accumulation of oligomerized amylin affects brain function.

METHODS: In contrast to amylin from humans, rodent amylin is neither amyloidogenic nor cytotoxic. …

Role Of Chronic Inflammation On Liver Function During Cachexia Progression In The ApcMin/+ Mouse Model, Aditi Narsale

Theses and Dissertations

Cachexia is a multifactorial syndrome that manifests during the advanced stage of chronic diseases and is characterized by a progressive loss of body mass sustained by underlying inflammation. The ApcMin/+ mouse is an established model of cachexia that exhibits a gradual loss of body mass correlating with increasing tumor burden and plasma IL – 6 levels. Moreover it also mimics other secondary characteristics observed in cachectic patients like splenomegaly, elevated plasma endotoxin levels, gut barrier dysfunction, hypogonadism and an overall hypermetabolic state. Liver controls the energy metabolism in the body by regulating glucose and lipid metabolism, glycogen storage, filtration of …

Dissecting The Roles Of Trim24 In Regulation Of Hepatic Lipid Metabolism And Inflammation, Lindsey C. Minter

Dissertations & Theses (Open Access)

DISSECTING THE ROLES OF TRIM24 IN REGULATION OF HEPATIC LIPID

METABOLISM AND INFLAMMATION

Lindsey Cauthen Minter, B.S., B.A.

Advisory Professor: Michelle C. Barton, Ph.D.

In this dissertation, I report the characterization of a new mouse model that recapitulates development of hepatocellular carcinoma (HCC) following spontaneous hepatic lipid accumulation, inflammation, and damage of liver tissue, due to complete loss of Trim24 expression. In human HCC and other cancers, TRIM24 expression is aberrantly high, while deletion of TRIM24 in the mouse has been shown to act as a liver specific tumor suppressor. The hypothesis tested here was that TRIM24, the E3 ubiquitin …

Transition From An M1 To A Mixed Neuroinflammatory Phenotype Increases Amyloid Deposition In App/Ps1 Transgenic Mice, Erica M. Weekman, Tiffany L. Sudduth, Erin L. Abner, Gabriel J. Popa, Michael D. Mendenhall, Holly M. Brothers, Kaitlyn Braun, Abigail Greenstein, Donna M. Wilcock

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: The polarization to different neuroinflammatory phenotypes has been described in early Alzheimer's disease, yet the impact of these phenotypes on amyloid-beta (Aβ) pathology remains unknown. Short-term studies show that induction of an M1 neuroinflammatory phenotype reduces Aβ, but long-term studies have not been performed that track the neuroinflammatory phenotype.

METHODS: Wild-type and APP/PS1 transgenic mice aged 3 to 4 months received a bilateral intracranial injection of adeno-associated viral (AAV) vectors expressing IFNγ or green fluorescent protein in the frontal cortex and hippocampus. Mice were sacrificed 4 or 6 months post-injection. ELISA measurements were used for IFNγ protein levels and …

Osteopontin: A Novel Regulator At The Cross Roads Of Inflammation, Obesity And Diabetes, Florian Kahles, Hannes M. Findeisen, Dennis Bruemmer

Gill Heart & Vascular Institute Faculty Publications

Since its first description more than 20 years ago osteopontin has emerged as an active player in many physiological and pathological processes, including biomineralization, tissue remodeling and inflammation. As an extracellular matrix protein and proinflammatory cytokine osteopontin is thought to facilitate the recruitment of monocytes/macrophages and to mediate cytokine secretion in leukocytes. Modulation of immune cell response by osteopontin has been associated with various inflammatory diseases and may play a pivotal role in the development of adipose tissue inflammation and insulin resistance. Here we summarize recent findings on the role of osteopontin in metabolic disorders, particularly focusing on diabetes and …

Il-4 Signaling Drives A Unique Arginase+/Il-1Β+ Microglia Phenotype And Recruits Macrophages To The Inflammatory Cns: Consequences Of Age-Related Deficits In Il-4rα After Traumatic Spinal Cord Injury, Ashley M. Fenn, Jodie C.E. Hall, John C. Gensel, Phillip G. Popovich, Jonathan P. Godbout

Spinal Cord and Brain Injury Research Center Faculty Publications

Alternative activation of microglia/macrophages (M2a) by interleukin (IL)-4 is purported to support intrinsic growth and repair processes after CNS injury. Nonetheless, alternative activation of microglia is poorly understood in vivo, particularly in the context of inflammation, injury, and aging. Here, we show that aged mice (18-19 months) had reduced functional recovery after spinal cord injury (SCI) associated with impaired induction of IL-4 receptor α (IL-4Rα) on microglia. The failure to successfully promote an IL-4/IL-4Rα response in aged mice resulted in attenuated arginase (M2a associated), IL-1β, and chemokine ligand 2 (CCL2) expression, and diminished recruitment of IL-4Rα⁺ macrophages to …

The Effect Of Mutations In Prmt5 On Its Ability To Oligomerize, Rachel Scarl

Senior Honors Projects

Atherosclerosis is a cardiovascular disease caused by a chronic inflammatory response in the cells lining blood vessels, vascular endothelial cells. In these cells, a network of interacting proteins regulates inflammation. One of these proteins, PRMT5, regulates the inflammatory response by methylating other proteins involved in inflammation. For PRMT5 to carry out its function, it must first oligomerize with itself and various other proteins. In this study, I determined whether mutations to specific PRMT5 methylation sites affect its ability to oligomerize. By expressing PRMT5 in HEK293 cells and studying the effects of adding a chemical cross-linking agent, DMS, I was able …

Benefits Of Exercise Intervention In Reducing Neuropathic Pain, John L. Dobson, James L. Mcmillan, Li Li

Department of Health Sciences and Kinesiology Faculty Publications

Peripheral neuropathy is a widespread and potentially incapacitating pathological condition that encompasses more than 100 different forms and manifestations of nerve damage. The diverse pathogenesis of peripheral neuropathy affects autonomic, motor and/or sensory neurons, and the symptoms that typify the condition are abnormal cutaneous sensation, muscle dysfunction and, most notably, chronic pain. Chronic neuropathic pain is difficult to treat and is often characterized by either exaggerated responses to painful stimuli (hyperalgesia) or pain resulting from stimuli that would not normally provoke pain (allodynia). The objective of this review is to provide an overview of some pathways associated with the development …

Microbiota, Oral Microbiome, And Pancreatic Cancer, Dominique S. Michaud, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Only 30% of patients diagnosed with pancreatic cancer survive one year post-diagnosis. Progress in understanding the causes of pancreatic cancer has been made, including solidifying the associations with obesity and diabetes, and a proportion of cases should be preventable through lifestyle modifications. Unfortunately, identifying reliable biomarkers of early pancreatic cancer has been extremely challenging, and no effective screening modality is currently available for this devastating form of cancer. Recent data suggest the microbiota may play a role in the disease process, but many questions remain. Future studies focusing on the human microbiome, both etiologically and as a marker of disease …

Therapeutic Implications Of Estrogen For Cerebral Vasospasm And Delayed Cerebral Ischemia Induced By Aneurysmal Subarachnoid Hemorrhage., Dale Ding, Robert M Starke, Aaron S Dumont, Gary K Owens, David M Hasan, Nohra Chalouhi, Md, Ricky Medel, Chih-Lung Lin

Department of Neurosurgery Faculty Papers

Cerebral vasospasm (CV) remains the leading cause of delayed morbidity and mortality following aneurysmal subarachnoid hemorrhage (SAH). However, increasing evidence supports etiologies of delayed cerebral ischemia (DCI) other than CV. Estrogen, specifically 17 β -estradiol (E2), has potential therapeutic implications for ameliorating the delayed neurological deterioration which follows aneurysmal SAH. We review the causes of CV and DCI and examine the evidence for E2-mediated vasodilation and neuroprotection. E2 potentiates vasodilation by activating endothelial nitric oxide synthase (eNOS), preventing increased inducible NOS (iNOS) activity caused by SAH, and decreasing endothelin-1 production. E2 provides neuroprotection by increasing thioredoxin expression, decreasing c-Jun N-terminal …

Blockade Of Mast Cell Activation Reduces Cutaneous Scar Formation, Lin Chen, Megan Schrementi, Matthew J. Ranzer, Traci A. Wilgus, Luisa A. Dipietro

Faculty Publications & Research

Damage to the skin initiates a cascade of well-orchestrated events that ultimately leads to repair of the wound. The inflammatory response is key to wound healing both through preventing infection and stimulating proliferation and remodeling of the skin. Mast cells within the tissue are one of the first immune cells to respond to trauma, and upon activation they release pro-inflammatory molecules to initiate recruitment of leukocytes and promote a vascular response in the tissue. Additionally, mast cells stimulate collagen synthesis by dermal fibroblasts, suggesting they may also influence scar formation. To examine the contribution of mast cells in tissue repair, …

Cervical Remodeling/Ripening At Term And Preterm Delivery: The Same Mechanism Initiated By Different Mediators And Different Effector Cells, Juan Miguel Gonzalez Velez

Wayne State University Dissertations

Premature cervical remodeling/ripening is believed to contribute to preterm delivery (PTD), the leading cause of perinatal morbidity and mortality. Despite considerable research, the causes of term and PTD remain unclear, and there is no effective treatment for PTD. We tested the hypothesis that complement activation plays a role in cervical remodeling and PTD. We studied cervical remodeling at term.

We studied two mouse models of inflammation-induced PTD. The first model was induced by vaginal administration of lipopolysaccharide (LPS)and the second one by administration of progesterone antagonist RU486. Increased cervical C3 deposition and macrophage infiltration and increased serum C3adesArg and C5adesArg …

Effect Of Tumor Necrosis Factorα On Expression Of Heme-Oxgenase1 In Human Gingival Fibroblasts, Jay Patel

PCOM Biomedical Studies Student Scholarship

Periodontitis is a chronic inflammatory disease that is characterized by activation of gingival fibroblasts to produce matrix metalloproteinases and other inflammatory mediators that contribute to destruction of tissues surrounding the teeth. In the United States, 22% of adults have a mild form of periodontal disease and 13% suffer from a severe form of the disease. In addition to tooth loss, periodontitis is associated with increased risk of several conditions, including diabetes, osteoporosis, rheumatoid arthritis and cardiovascular disease. Heme oxygenase-1 (HO-1) is activated by a wide variety of stressful stimuli and levels are increased in inflamed tissues. HO-1 degrades free heme, …

The Molecular Mechanisms Underpinning The Therapeutic Properties Of Oleanolic Acid, Its Isomer And Derivatives For Type 2 Diabetes And Associated Complications, Danielle Camer, Yinghua Yu, Alexander Szabo, Xu-Feng Huang

Illawarra Health and Medical Research Institute

Recent research has uncovered the molecular mechanisms responsible for the therapeutic properties of oleanolic acid (OA), its isomer ursolic acid (UA), and derivatives. In particular, recent reports have highlighted the benefits of these compounds in the prevention and treatment of type 2 diabetes and associated life-threatening complications, such as nonalcoholic fatty liver disease, nephropathy, retinopathy, and atherosclerosis. The prevalence of type 2 diabetes is of major concern since it is reaching global epidemic levels. Treatments targeting the signaling pathways altered in type 2 diabetes are being actively investigated, and OA and UA in natural and derivative forms are potential candidates …

The Common Acid Sphingomyelinase Polymorphism P.G508r Is Associated With Self-Reported Allergy, Martin Reichel, Tanja Richter-Schmidinger, Christiane Muhle, Cosima Rhein, Panagiotis Alexopoulos, Sibylle G. Schwab, Erich Gulbins, Johannes Kornhuber

Illawarra Health and Medical Research Institute

Background: Acid sphingomyelinase (ASM) is a key regulator of ceramide-dependent signalling pathways. Among others, activation of ASM can be induced by CD95 or cytokine signalling and by cellular stress resulting from inflammation or infection. Increased ASM activity was observed in a variety of human diseases including inflammatory and neuropsychiatric disorders. We hypothesized that basal ASM activity might influence the susceptibility for common human diseases. Methods: The general health condition of 100 young people was assessed using a questionnaire. The ASM polymorphism rs1050239 (c.1522G>A; encoding p.G508R) was determined from genomic DNA. Activities of secretory (S-) and lysosomal (L-) ASM were …

Hypochlorite-Induced Structural Modifications Enhance The Chaperone Activity Of Human Α2-Macroglobulin, Amy Wyatt, Janet Kumita, Richard W. Mifsud, Cherrie A. Gooden, Mark Wilson, Christopher M. Dobson

Faculty of Science, Medicine and Health - Papers: part A

Hypochlorite, an oxidant generated in vivo by the innate immune system, kills invading pathogens largely by inducing the misfolding of microbial proteins. Concomitantly, the nonspecific activity of hypochlorite also damages host proteins, and the accumulation of damaged (misfolded) proteins is implicated in the pathology of a variety of debilitating human disorders (e.g., Alzheimer's disease, atherosclerosis, and arthritis). It is well-known that cells respond to oxidative stress by up-regulating proteostasis machinery, but the direct activation of mammalian chaperones by hypochlorite has not, to our knowledge, been previously reported. In this study, we show that hypochlorite-induced modifications of human α2-macroglobulin (α2M) markedly …

Receptor Of Advanced Glycation Endproducts (Rage) Is Positively Correlated With Tumor Necrosis Factor-Α In Adolescents With Obesity, Tasnim Rahman, Daniel H. Conrad, Anshu Gupta

Undergraduate Research Posters

Introduction: Obesity in childhood is associated with an increased prevalence of diabetes and other traditional cardiometabolic risk factors, suggesting an epidemic of premature cardiovascular disease among today’s youth. Glycotoxins, known as advanced glycationend products (AGE’s), activating via the membrane-bound receptors (mRAGE), have been implicated in the pathophysiology of inflammation, (increased tumor necrosis factor-α [TNF-α ]), insulin resistance and vascular dysfunction in adults, but the role of RAGE in the early stages of metabolic disorders is unknown. In this study, we assessed relationship of cardiometabolicrisk factors, mRNA expression of TNF-α and RAGE in peripheral monocytes in adolescents with obesity.

Methods: Thirty …

Effects Of Olanzapine On The Elevation Of Macrophage Infiltration And Pro-Inflammatory Cytokine Expression In Female Rats, Qingsheng Zhang, Meng He, Chao Deng, Hongqin Wang, Xu-Feng Huang

Illawarra Health and Medical Research Institute

The metabolic side-effects of olanzapine have undermined drug compliance and increased concern for this otherwise-effective treatment for schizophrenia. As obesity and type 2 diabetes are associated with low-grade inflammation, and olanzapine-induced weight gain has three typical stages, the current study investigated the inflammatory effects of olanzapine in three treatment stages. Female Sprague-Dawley rats were treated orally with olanzapine (1 mg/kg three times daily) or vehicle for one week, two weeks, and five weeks. Olanzapine significantly increased body weight and white visceral fat deposition in all three treatment stages compared to control. Olanzapine enhanced average adipocyte size and level of macrophage …
