Abstract Background Exacerbations of Chronic obstructive pulmonary disease COPD are an important cause of the morbidity and mortality associated with the disease. Strategies to reduce exacerbation frequency are thus urgently required and depend on an understanding of the inflammatory milieu associated with exacerbation episodes. Bacterial colonisation has been shown to be related to the degree of airflow obstruction and increased exacerbation frequency. The aim of this study was to asses the kinetics of cytokine release from COPD parenchymal explants using an ex vivo model of lipopolysaccharide LPS induced acute inflammation. Methods Lung tissue from 24 patients classified by the GOLD guidelines 7F 17M age yrs FEVI of predicted and 13 subjects with normal lung function 8F 5M age yrs FEVI
