Symptoms, Cytokines, And Quality Of Life Of Patients With Chronic Graft-Versus-Host Disease Following Allogeneic Hematopoietic Stem Cell Transplantation, Debra Kelly

Theses and Dissertations

Introduction: Chronic graft-versus-host disease (cGVHD) is a serious complication following allo-HSCT characterized by immune dysregulation, organ dysfunction, risk for infection, and distressing symptoms. Complications may include scleroderma, hepatic dysfunction and bronchiolitis obliterans. Advances in allo-HSCT for many hematologic dyscrasias (e.g. acute and chronic leukemias, aplastic anemia, and myelodysplastic syndrome) have improved survival which has generated a renewed focus on survivorship issues. Distressing symptoms are noted as negatively impacting quality of life (QoL). The relationship between inflammation and behavioral responses may impact symptoms. Examining patterns and levels of inflammation with symptoms is relevant. Objective: The aims of this study were to …

Transformation Of Human Mast Cells By Interferon-Gamma And The Potential Role Of Myeloid Derived Suppressor Cells In Mastocytosis., Sahar Lotfi-Emran

Theses and Dissertations

Mast cells respond to a variety of signals, are associated with both increased inflammation and regulation of the immune response, and are able to interact with a variety of hematopoietic and non-hematopoietic cells. The majority of the work that highlights mast cell pleiotropic abilities has been completed in murine models. Though these models have significantly advanced our understanding of what mast cells can do, they cannot inform us as to what mast cells actually do in human beings. The goal of this dissertation is to assess fully mature, primary human mast cell function beyond the well-defined type 1 hypersensitivity function …

The Effect Of Obesity On Il-1Β, Il-1ra, And Leptin Following Acute Mental Stress, Heather Caslin

Theses and Dissertations

Research regarding the development of cardiovascular disease (CVD) is important because CVD is the leading cause of death in the United States (US) and many countries abroad. Risk factors, such as obesity and psychological stress, should be studied in order to understand contributing factors for CVD and the cellular mechanisms which link risk factors with the development of disease. Specifically, the combined influence of multiple risk factors on inflammation is of interest because many individuals have more than one risk factor, which additively increases an individual’s risk for CVD. Obesity is already characterized by disordered inflammation, which suggests that the …

Epigenetic Alterations Of Toll-Like Receptors By Tet2 In Spontaneous Preterm Labor, Anuja Chumble

Theses and Dissertations

Increasing evidence implicates the presence of bacteria in intrauterine tissues as an important risk factor for spontaneous preterm labor. Epigenetic alterations of innate immunity genes may increase the mother’s sensitivity to subclinical levels of bacteria. This study examined the presence of TET2, TLR-2, and TLR-9 in intrauterine tissue, and evaluated whether epigenetic alterations of these genes, as well as IL-8, changed their expression in human decidual tissue and a macrophage cell culture. Immunohistochemicalstaining was used to detect the presence of these proteins in intrauterine tissue. Gene expression changes were evaluated in stimulated monocytes and macrophages. Fluorescence immunohistochemistry was used to …

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 …
