The Role of T Cells in the Regulation of Acrolein-Induced Pulmonary Inflammation and Epithelial-Cell Pathology

This report describes a study to investigate the role of two subpopulations of T cells in the airway response to inhaled acrolein, a toxic pollutant in ambient air, which US EPA's National Air Toxics Assessment has identified as having broad effects. Dr. Michael Borchers and colleagues measured inflammation and injury in response to acrolein in the lungs of mice that are genetically deficient in the specific T-cell subpopulations. He also measured changes in gene expression in the T-cell subpopulations after acrolein exposure. This study was funded under the Walter A. Rosenblith New Investigator Award.
