Abstract Background The major risk factor for the development of COPD is cigarette smoking. Smoking causes activation of resident cells and the recruitment of inflammatory cells into the lungs which leads to release of pro-inflammatory cytokines chemotactic factors oxygen radicals and proteases. In the present study evidence is found for a new cellular mechanism that refers to a link between smoking and inflammation in lungs. Methods Employing human monocyte-derived macrophages different techniques including FACS analysis Cytometric Bead .
