Pulmonary Stress in the Alcoholic and Obese LungIn the United States today, alcoholism and obesity are increasingly becoming issues for a vast age group from young children to geriatric adults. Alcoholism and obesity have been extensively studied as separate entities that have been proven to change metabolism and cause over-lapping health issues, which prompted us to study them in conjunction with one another, especially in the lungs. One major link between these two alarmingly common problems is Krüppel-Like Factor 4 (KLF4), a cell regulatory protein crucial to cellular normality and monocyte differentiation. This particular study highlights the effects alcoholism and obesity have on the lung, specifically epithelial cells (L2) and macrophages (AM). The goal of this project is to measure the KLF4 expression in the L2 and AM cells subjected to high ethanol (EtOH) consumption, high glucose consumption, high EtOH and glucose consumption, as well as a healthy control lung in to explain the mechanism behind decreased immune function in these patients.
