Using an analogous novel in vitro system to model both the healthy and inflamed lung, the susceptibility of epithelial cells exposed to DEP of varying organic carbon content was studied. Murine LA-4 alveolar type II-like epithelial cells, as well as primary murine tracheal epithelial cells (MTE), were treated with exogenous cytokines (tumor necrosis factor [TNF] α + interleukin [IL]-1 β + interferon [IFN] γ) to model a mild inflammatory state. Epithelial cells were subsequently exposed to DEP of varying organic carbon content, and the resultant cytotoxic, cytoprotective, or antioxidant cell responses were inferred by changes in lactate dehydrogenase (LDH) release, heme oxygenase-1 (HO-1) expression, or glutathione levels, respectively. Data showed that exposure of healthy LA-4 cells to organic carbon-rich DEP (25 μg/cm2; 24 h) induced adaptive cytoprotective/antioxidant responses with no apparent cell injury. In contrast, exposure of inflamed LA-4 cells resulted in oxidative stress culminating in significant cytotoxicity. Exposure of healthy MTE cells to organic carbon-rich DEP (20 μg/cm2; 24 h) was seemingly without effect, whereas exposure of inflamed MTE cells resulted in increased epithelial solute permeability. Thus, surface lung epithelial cells stressed by a state of inflammation and then exposed to organic carbon-rich DEP appear unable to respond to the additional oxidative stress, resulting in epithelial barrier dysfunction and injury. Adverse health outcomes associated with exposure to traffic-related air pollutants, like DEP, in patients with preexisting inflammatory respiratory diseases may be due, in part, to similar mechanisms.}, number={8}, journal={JOURNAL OF TOXICOLOGY AND ENVIRONMENTAL HEALTH-PART A-CURRENT ISSUES}, author={Manzo, Nicholas D. and Slade, Ralph and Richards, Judy H. and McGee, John K. and Martin, Linda D. and Dye, Janice A.}, year={2010}, pages={565–580} } @article{lagier_manzo_carll_jaskot_slade_richards_winsett_farraj_dye_2008, title={A Hyperlipidemic Rabbit Model Provides New Insights into Pulmonary Zinc Exposure Effects on Cardiovascular Health}, volume={8}, ISSN={["1530-7905"]}, DOI={10.1007/s12012-008-9028-9}, number={4}, journal={CARDIOVASCULAR TOXICOLOGY}, author={LaGier, Adriana J. and Manzo, Nick D. and Carll, Alex P. and Jaskot, Richard H. and Slade, Ralph and Richards, Judy H. and Winsett, Darrell W. and Farraj, Aimen K. and Dye, Janice A.}, year={2008}, month={Dec}, pages={195–206} }
