Effects Of Cpla-2 On The Migration And Proliferation Of Human Vascular Smooth Muscle Cells And The 2-D Migratory Patterns Of Tropomyosin In Femoral And Abdominal Aorta Tissue, Jaimeson Thomas Powell Jan 2014

Effects Of Cpla-2 On The Migration And Proliferation Of Human Vascular Smooth Muscle Cells And The 2-D Migratory Patterns Of Tropomyosin In Femoral And Abdominal Aorta Tissue, Jaimeson Thomas Powell

Abstract 1: Platelet derived growth factor BB (PDGF BB) has an important influence on smooth muscle cell proliferation in restenosis and atherosclerosis. Our understanding of different signal transduction pathways involved in the response of smooth muscle cells to PDGF BB is potentially significant for understanding and manipulating these processes. Prior studies have demonstrated a crucial activation of cytosolic phospholipase A2 (cPLA2) in smooth muscle cells to PDGF BB with the production of arachidonic acid and prostaglandin E2. In these studies we investigated the role for another PLA2, calcium-independent PLA2 (iPLA2) in comparison to cPLA2 on smooth muscle cell migration and …


The Role Of Microrna In Staphylococcal Enterotoxin B-Induced Inflammation And Acute Lung Injury, Roshni Rao Jan 2014

The Role Of Microrna In Staphylococcal Enterotoxin B-Induced Inflammation And Acute Lung Injury, Roshni Rao

Theses and Dissertations

Staphylococcal enterotoxin B (SEB) is a potent activator of the Vβ8+T-cells leading to the proliferation of nearly 30% of the T-cell pool. As a consequence, excessive amounts of cytokine mediators are released leading to extensive tissue damage and sometimes toxic shock and death. Due to the ease with which SEB can be aerosolized anddisseminated, it is considered a biological weapon. In the current study, we investigated the pro-inflammatory effects of SEB in two mouse models of acute inflammatory lung injury. Specifically, while inflammatory cues are known to elicit changes in key transcriptional factors and gene expression, we explored for the …


An Evolutionary Perspective On Infectious And Chronic Disease, John Eberth Jan 2014

An Evolutionary Perspective On Infectious And Chronic Disease, John Eberth

Theses and Dissertations

The integration of evolutionary biology with traditional medicine can elucidate novel mechanisms of contemporary disease. Whereas the goal of traditional medicine is to treat and cure the proximate causes, evolutionary biology aims to understand the driving forces behind why humans are susceptible to disease. To form the basis of this hypothesis we postulate that modern man's current genetic information was programmed at a time, and in an environment, that is not relevant to today's human populations. The discordance between these genes of our ancestors and the environment of contemporary humans is thought to be a major reason for the increase …
