The Impact Of Microbial Experience On The Murine Innate Immune Response, Cody Thomas Morrison
The Impact Of Microbial Experience On The Murine Innate Immune Response, Cody Thomas Morrison
Masters Theses
The hygiene hypothesis predicts that certain environmental factors shape overall immune system function in animals and humans. While current specific pathogen free (SPF) mouse models are invaluable for studying the immune system, they have limitations for comparison with humans who have microbial exposures throughout their lifetimes. Several studies have shown that the composition of the immune system of SPF mice more closely resembles that of newborns, whereas the immune system from mice exposed to microbial pathogens more closely reflect adult immunity. In this study we have established a model using traditional SPF mice (“clean mice”) and SPF mice that were …
Prevention Of Chronic Inflammation By Targeting Macrophage Integrin Adb2, Cady Forgey
Prevention Of Chronic Inflammation By Targeting Macrophage Integrin Adb2, Cady Forgey
Electronic Theses and Dissertations
Macrophage integrin aDb2 promotes macrophage retention and accumulation within inflamed tissue, a key event in development of chronic inflammation. Recently, the P5 peptide was identified as a specific inhibitor for integrin aDb2 interaction with 2-(ω-carboxyethyl) pyrole (CEP), a ligand at inflammatory sites. This thesis aims to identify integrin aD I-domain amino acids involved in binding P5 peptide and likewise to CEP. We propose that non-conserved, basic amino acids of the integrin aDb2 I-domain are responsible for binding to P5 peptide and likewise to CEP. Eight amino acids were analyzed by …
Role Of Ceramide-1 Phosphate In Regulation Of Sphingolipid And Eicosanoid Metabolism In Lung Epithelial Cells, Brittany A. Dudley
Role Of Ceramide-1 Phosphate In Regulation Of Sphingolipid And Eicosanoid Metabolism In Lung Epithelial Cells, Brittany A. Dudley
USF Tampa Graduate Theses and Dissertations
Ceramide 1-Phosphate (C1P) is a sphingolipid metabolite which plays a large role in inflammation, cell survival and proliferation1. C1P is known to have both pro- and anti-apoptotic roles in lung cancer cells, governed by ceramide kinase (CERK), upstream of precursor ceramide (Cer)2. Previous work reveals C1P serves as the liaison between sphingolipid and eicosanoid synthesis, by decreasing the dissociation rate of group IVA cytosolic PLA2 (cPLA2α) from the Golgi membrane, C1P directly activates this phospholipase for downstream eicosanoid synthesis and subsequent inflammatory response3. CERK has been discovered to modulate eicosanoid synthesis, …
Protection Against Atherosclerosis By A Non-Native Pentameric Crp That Shares Its Ligand Recognition Functions With An Evolutionarily Distant Crp, Asmita Pathak
Electronic Theses and Dissertations
C-reactive protein (CRP) is an acute phase protein of the innate immune system that has been evolutionarily conserved. Human CRP is known to exist in two different pentameric conformations; native CRP and non-native CRP that possess differential ligand recognition functions. The structure of CRP evolved from arthropods to humans, in terms of subunit composition, disulfide bonds, and glycosylation pattern. Along with change in structure, the gene expression pattern of CRP also evolved from a constitutive protein in lower invertebrates to an acute phase protein in humans. The objective of this study was to determine the function of a non-native pentameric …
The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine
The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine
Theses and Dissertations
Patients with severe lung pathologies, such as Acute Respiratory Distress Syndrome (ARDS), often require mechanical ventilation as a clinical intervention; however, this procedure frequently exacerbates the original pulmonary issue and produces an exaggerated inflammatory response that potentially leads to sepsis, multisystem organ failure, and mortality. This acute lung injury (ALI) condition has been termed Ventilator-Induced Lung Injury (VILI). Alveolar overdistension, cyclic atelectasis, and biotrauma are the primary injury mechanisms in VILI that lead to the loss of alveolar barrier integrity and pulmonary inflammation. Stress and strains during mechanical ventilation are believed to initiate alveolar epithelial mechanotransduction signaling mechanisms that contribute …
