Bariatric Surgery Impacts Immune Cell Metabolism And Function Dependent On Metabolic Status, Samantha N. Hart

University of Kentucky Doctoral Dissertations

Type 2 Diabetes (T2D), one of the top ten causes of death worldwide, is fueled by chronic inflammation. T2D is considered a metabolic disease, and there is a great push to target metabolic and associated inflammatory pathways to ameliorate the disease & its comorbidities i.e., obesity and cardiovascular disease. Thus far, clinical trials of anti-inflammatory drugs have had modest impacts on T2D and have not led to changes in clinical practice. This may in part be due to a gap in knowledge in the mechanism(s) driving obesity-associated chronic inflammation. I posit that metabolic abnormalities in immune cells in those with …

Mechanism-Driven Therapy For Diabetic Cardiovascular Disease, Fabian Sanchis-Gomar, Carl J. Lavie, Salvatore Carbone, Ian J. Neeland

EVMS School of Health Professions Faculty Publications

[Introduction] Diabetic cardiovascular disease is a network disorder, not a glucose-only complication

Diabetes accelerates cardiovascular (CV) target-organ damage through multiple interacting biological modules that amplify risk even when glycemia is modestly controlled^[1]. These modules include (i) adipose tissue dysfunction with altered adipokine secretion and immune-cell infiltration; (ii) ectopic lipid deposition in liver, myocardium, and perivascular/epicardial fat (iii) endothelial dysfunction with impaired nitric oxide bioavailability and heightened oxidative stress (iv) chronic kidney disease (CKD)-mediated volume, pressure, and uremic-toxin stress, and (v) autonomic and neurohormonal activation that promotes hypertension, arrhythmias, and remodeling^[1]. The clinical spectrum includes macrovascular disease …

The Effect Of Fructose Metabolism On Hepatic De Novo Lipogenesis And Adipose Tissue Insulin Resistance, Taghreed Ibrahim Fadhul

Theses and Dissertations--Nutritional Sciences

There is a worldwide epidemic of obesity and metabolic dysfunction. The root cause of obesity is driven by a positive energy balance, which is a consequence of increased caloric intake and decreased energy expenditure. Energy intake is the more dominant force, as increasing energy expenditure is a time-consuming and labor-intensive process. The caloric surplus can be mainly accounted for by increased consumption of high-fat and high-sugar diets. While the risks associated with fat consumption are well-documented, the impact of sugar intake is less understood.

Fructose is a simple sugar widely consumed in modern diets. Its intake has been associated with …

The Role Of Lymph-Adipose Crosstalk In Alcohol-Induced Perilymphatic Adipose Tissue Dysfunction, Kourtney D. Weaver, Liz Simon, Patricia E. Molina, Flavia Souza-Smith

School of Graduate Studies Faculty Publications

Chronic alcohol use leads to metabolic dysfunction in adipose tissue. The underlying mechanisms and the contribution of alcohol-induced adipose tissue dysfunction to systemic metabolic dysregulation are not well understood. In our previous studies, we found that chronic alcohol feeding induces mesenteric lymphatic leakage, perilymphatic adipose tissue (PLAT) inflammation, and local insulin resistance in rats. The goal of this study was to further explore the link between alcohol-induced lymphatic leakage and PLAT immunometabolic dysregulation, locally and systemically, using in vivo and ex vivo approaches. Male rats received a Lieber–DeCarli liquid diet, of which 36% of the calories were from alcohol, for …

The Effects Of Sglt2 Inhibitors In Patients With Metabolic Dysfunction-Associated Fatty Liver Disease; A Narrative Review, Mihaela Simona Popoviciu, Lorena Paduraru, Mominur Rahman, Fatema Akter Supti, Roxana Adriana Stoica, Delia Reurean Pintilei, Cristina Ioana Bica, Simona Cavalu

Journal of Mind and Medical Sciences

Worldwide, metabolic dysfunction-associated fatty liver disease (MAFLD) is a significant public health concern, especially since more than fifty percent of people with type 2 diabetes are affected by it. This pathological condition includes all states of fatty liver disease, from non-alcoholic fatty liver disease (NAFLD) to steatohepatitis (NASH). Prolonged evolutions can lead to cirrhosis and cancer, so treatment must be started early. Hepatic steatosis may be improved by sodium glucose co-transporter 2 inhibitors (SGLT2 inhibitors), which prevent glucose reabsorption in the proximal renal tubule and increase urinary excretion, thus lowering plasma glucose levels. Experimental studies in animal models have suggested …

The Impact Of Eggs On Inflammatory And Immune Profiles In Women With Polycystic Ovary Syndrome (Pcos), Clara Martin

Honors Scholar Theses

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder affecting approximately 5-15% of women of reproductive age. Characterized by symptoms such as hyperandrogenism, ovulatory dysfunction, and insulin resistance, PCOS is also linked with significant health complications including metabolic syndrome, cardiovascular diseases, and type 2 diabetes. Recent studies highlight the critical role of immune dysfunction and chronic inflammation in exacerbating PCOS pathology, suggesting that managing these immune responses could alleviate the broader health impacts of the disorder.

Nutritional interventions, particularly those targeting immune and inflammatory pathways, have emerged as promising strategies for managing PCOS. Among various dietary components, the intake of …

The Role Of Micrornas In Cellular Senescence, Inflammation, And Cancer Induced By Childhood Obesity, Sarah S. Siddiqi

Honors Undergraduate Theses

Childhood obesity has escalated into a major public health crisis with serious implications for long-term health. As obesity rates among children continue to rise globally, it is crucial to understand its effects on cellular aging and inflammation—key processes that underpin many metabolic diseases. Obesity not only directly contributes to various metabolic disorders but also disrupts fundamental cellular mechanisms, accelerating aging and fostering systemic inflammation. By examining the impact of obesity on cellular aging and chronic inflammation, as well as the regulatory role of microRNAs (miRNAs) in these pathways, we have been able to identify critical biomarkers and molecular mechanisms involved …

Irritable Bowel Syndrome: Proposed Mechanisms Of Pathophysiology And The Underlying Dysregulation Of Brain-Gut Interaction, Hailey Haddix

Senior Honors Theses

Irritable bowel syndrome (IBS) is a disease of the gastrointestinal tract affecting approximately 11-21% of people worldwide (Xiao et al., 2021). This research focuses on the dysregulation of gut homeostasis in IBS and explains how the pathophysiology of the gut is controlled by the bidirectional brain-gut axis. The mechanisms of the brain-gut axis consist of neuro-immune cross talk, neuro-hormone cross talk, microbiome-gut signaling, and the HPA-axis. Each of these contribute to one or more of the possible phenotypes of gut pathophysiology, which could include intestinal permeability, visceral hypersensitivity, and motility disturbance (Xiao et al., 2021). Stress is also an important …

Background: Low-density neutrophils (LDN) are increased in several inflammatory diseases and may also play a role in the low-grade chronic inflammation associated with obesity. Here we explored their role in obesity, determined their gene signatures, and assessed the effect of bariatric surgery. Methods: We compared the number, function, and gene expression profiles of circulating LDN in morbidly obese patients (MOP, n=27; body mass index (BMI) > 40 Kg/m2) and normal-weight controls (NWC, n=20; BMI < 25 Kg/m2) in a case-control study. Additionally, in a prospective longitudinal study, we measured changes in the frequency of LDN after bariatric surgery (n=36) and tested for associations with metabolic and inflammatory parameters. Findings: LDN and inflammatory markers were significantly increased in MOP compared to NWC. Transcriptome analysis showed increased neutrophil-related gene expression signatures associated with inflammation, neutrophil activation, and immunosuppressive function. However, LDN did not suppress T cells proliferation and produced low levels of reactive oxygen species (ROS). Circulating LDN in MOP significantly decreased after bariatric surgery in parallel with BMI, metabolic syndrome, and inflammatory markers. Interpretation: Obesity increases LDN displaying an inflammatory gene signature. Our results suggest that LDN may represent a neutrophil subset associated with chronic inflammation, a feature of obesity that has been previously associated with the appearance and progression of co-morbidities. Furthermore, bariatric surgery, as an efficient therapy for severe obesity, reduces LDN in circulation and improves several components of the metabolic syndrome supporting its recognized anti-inflammatory and beneficial metabolic effects.

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 …

Dietary Assessments And Their Association With Psychological Factors, Inflammation, And Cardiovascular Health Outcomes, Junghee Kang

Theses and Dissertations--Nursing

Cardiovascular diseases (CVDs), a group of disorders of the heart and blood vessels, are the leading cause of death worldwide, causing one-third of deaths each year. Diet is one of the most important behavioral risk factors for CVD. The effects of behavioral risk factors, such as diet, may lead to increased blood pressure, increased blood glucose, raised blood lipids, and overweight and obesity. Inflammation contributes to the development of CVD and can be influenced by diet. Dietary assessment indices can measure diet quality from an individual's dietary intake by scoring food and nutrient intakes. However, the mediation effects of diet …

The Interplay Of The Oral-Gut Microbiome With Chronic Inflammation In Rheumatoid Arthritis And Crohn's Disease, Anuradha Rampersaud

Mako: NSU Undergraduate Student Journal

Abstract

Rheumatoid Arthritis (RA) and Crohn’s Disease (CD) are both chronic inflammatory diseases that share developmental and treatment similarities. RA’s symptoms include swelling, stiffness, and pain in synovial joints, corresponding with bone and cartilage destruction. CD’s symptoms include abdominal pain, bowel obstruction, bloating, diarrhea, and fever. The purpose of this literature review was to investigate the links between these two diseases and propose future treatment and prevention targets. Current treatment for RA and CD aims to suppress inflammation by targeting its mediators. However, this review noted that there should be greater focus on resolving inflammation. Both diseases are characterized by …
