Increased Circulatory Lipopolysaccharide From A High Fat Diet Aggravates Inflammation And Exacerbates Renal Failure, Samuel Righi
Increased Circulatory Lipopolysaccharide From A High Fat Diet Aggravates Inflammation And Exacerbates Renal Failure, Samuel Righi
Theses and Dissertations
Kidney failure is frequently associated with the risk factors linked to metabolic syndrome. Lipopolysaccharide (LPS) is a potent inflammatory molecule, which has increased absorption from the gut into blood circulation following a high fat and high-energy diet. We hypothesized that LPS from a high fat diet can amplify inflammation, thereby exacerbating chronic kidney disease and associated disorders. We have found that adding a high fat diet to renal insufficient mice significantly progressed their kidney disease as well as associated disorders, compared to both a high fat diet and renal insufficiency alone. Additionally, we were able to demonstrate in vitro that …
The Group Iva Cytosolic Phospholipase A2/C1p Interaction And Its Role In Eicosanoid Synthesis And Inflammation, Jennifer A. Mietla
The Group Iva Cytosolic Phospholipase A2/C1p Interaction And Its Role In Eicosanoid Synthesis And Inflammation, Jennifer A. Mietla
Theses and Dissertations
In the presented study, we demonstrate that the interaction of group IVA cytosolic phospholipase A2 and ceramide-1-phosphate is crucial for production of eicosanoid synthesis in inflammation. Inflammation is a critical component of many disease states including anaphylaxis, cancer, cardiovascular disease, rheumatoid arthritis, diabetes and asthma. Eicosanoids are well established mediators of inflammation, and the initial rate limiting step in the production of eicosanoids is the liberation of arachidonic acid (AA) from membrane phospholipids by a phospholipase A2 (PLA2). The major phospholipase involved in this liberation of AA during the inflammatory response is group IVA cytosolic phospholipase A2 (cPLA2α). Previous studies …
The Effect Of Lactic Acid On Mast Cell Function, Andrew J. Spence
The Effect Of Lactic Acid On Mast Cell Function, Andrew J. Spence
Theses and Dissertations
This study shows for the first time the effect that L-(+)-lactic acid has on mast cell activation. Lactic acid is a byproduct of anaerobic glycolysis and is associated with inflammatory environments such as wounds, tumors and, asthma. In this study, pre-treatment with lactic acid altered cytokine production by bone marrow-derived mast cells (BMMC). Specifically, lactic acid enhanced cytokine secretion following IgE cross-linking, but decreased IL-33 mediated cytokine production. These effects were altered by genetic background, since C57BL/6 mast cells demonstrated the aforementioned result, but lactic acid had no effect on IgE-mediated cytokine production in 129/SvJ mast cells. The affected cytokines …
The Effect Of Fluvastatin On Mast Cell Function: Genotype Dependence, Elizabeth M. Kolawole
The Effect Of Fluvastatin On Mast Cell Function: Genotype Dependence, Elizabeth M. Kolawole
Theses and Dissertations
Fluvastatin, the HMG-CoA reductase inhibitor known for its role in the treatment of hypercholesterolemia and cardiovascular disease, has more recently been shown to play a role in the immune response. Given the critical role that mast cells play in allergy and inflammatory diseases such as asthma, which effects one third of America’s population, we assessed the effect of fluvastatin on mast cell and basophils function. We demonstrate that fluvastatin downregulated IgE-mediated cytokine production. Additionally, in vivo studies showed that fluvastatin suppressed IgE-mediated anaphylaxis. Interestingly, the effects of fluvastatin showed dependence on genetic background, as C57BL/6 mast cells were sensitive, while …
