Prevention Of Chronic Inflammation By Targeting Macrophage Integrin Adb2, Cady Forgey

Electronic Theses and Dissertations

Macrophage integrin a_Db₂ 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 a_Db₂ interaction with 2-(ω-carboxyethyl) pyrole (CEP), a ligand at inflammatory sites. This thesis aims to identify integrin a_D I-domain amino acids involved in binding P5 peptide and likewise to CEP. We propose that non-conserved, basic amino acids of the integrin a_Db₂ I-domain are responsible for binding to P5 peptide and likewise to CEP. Eight amino acids were analyzed by …

Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)

Electronic Theses and Dissertations

The observed overlap between genetic variants associated with both adiposity and inflammatory markers suggests that changes in both adiposity and inflammation could be partially mediated by common pathways. The pervasive but sparsely characterized “pleiotropic” genetic variants associated with both adiposity and inflammation have been hypothesized to provide insight into the shared biology. This study explored and characterized the genetic pleiotropy underpinning adiposity and inflammation using genetic and phenotypic observations from the Cameron County Hispanic Cohort (CCHC). A total of 3,313 samples and >9 million single nucleotide polymorphisms (SNPs) were examined in this study. Mixed model genome-wide association studies (GWAS) were …

Roles Of Endothelial Cell Heat Shock Protein A12b And Β-Glucan, A Reagent For Trained Immunity In The Regulation Of Inflammation In Sepsis, Fei Tu

Electronic Theses and Dissertations

Sepsis is dysregulated host immune response to infection causing life-threatening organ dysfunction. Endothelial cell dysfunction and uncontrolled inflammatory responses are two contributors for sepsis-induced mortality. The crosstalk between endothelial and immune cells plays a critical role in the pathophysiology of sepsis. Therefore, understanding the mechanism of interaction between endothelial and immune cells will provide novel information to develop therapeutic strategies for sepsis.

Pathogen associated moleculear patterns (PAMPs) and/or damage associated molecular patterns (DAMPs) produced during sepsis, activate endothelial cells to increase the expression of adhesion molecules, attracting immune cell infiltration into the tissues. Uncontrolled inflammatory responses during the early phase …

Pilot Study Exploring The Effect Of Targeted Cox-2 Inhibition In Macrophages Responding To Neuronal Injury; Promoting Enhanced Axonal Regeneration, Alyssa Brauckmann

Electronic Theses and Dissertations

Celecoxib nanoemulsion (CXB-NE) has been developed as a macrophage targeted analgesics by Dr. Janjic and her team at Duquesne University, (Janjic et al, 2018; Liu et al, 2020; Saleem et al, 2019b; Vasudeva et al, 2014). The CXB-NE nanoemulsion carrying a Nonsteroidal Anti-inflammatory (NSAID) inhibitor of COX-2 activity result in a reduction in PGE2 expression in macrophages. Using CXB-NE in rats that have peripheral nerve injury constricting the sciatic nerve relieves hypersensitivity, a pain-like behavior. The treatment also decreases inflammation associated with this chronic constriction injury (Janjic et al, 2018; Saleem et al, 2019b; Stevens et al, 2019). In this …

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 …

Physiological Responses To Feeding A Yeast Culture Supplement To Transition Dairy Cows, Nathaly Ana Carpinelli

Electronic Theses and Dissertations

The transition period is the dynamic stage in the lactation cycle, where the most metabolic changes can occur. The use of nutritional strategies, such as yeast culture, can help cows during the transition from pregnancy to early lactation, improving health and decreasing the incidence of metabolic disorders. The first objective of this research was to evaluate the effects of a commercial yeast culture product (YC; Cellerate Culture Classic HD, Phibro Animal Health, Teaneck, NJ) on performance, blood biomarkers, and rumen fermentation and bacterial population in dairy cows during the transition period through 50 days in milk (DIM). Overall, the results …
