      The adverse health risks associated with alcohol abuse and obesity are widely known by the general population. Although lesser known, studies have presented the lungs as secondary organs affected by such lifestyle factors. Healthy lungs are protected against infection and harmful airborne particles by macrophages, the working entities of the immune system which fight potential sources of infection. When these immune-responsive cells are compromised and unable to perform their functions, lung health may deteriorate. Therefore, a healthy pulmonary alveolar macrophage population is vital for adequate lung function. Chronic alcohol abuse and obesity have been shown to suppress alveolar macrophage function, thus lowering the lungs� first line of defense. The objective of this study is to determine the effects of exogenous ethanol and increased glucose concentration on macrophage size and viability via an�in vitro�study on NR8383 rat alveolar macrophages. The study measures macrophage viability under treatment conditions.
    • Pulmonary Stress in the Alcoholic and Obese Lung

      In 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.
