CD11b expression in the lung after 1 week smoke exposure. Representative photomicrographs (n = 3) of an immunohistological staining for CD11b (brown color, DAB staining) in lung tissue of air-exposed mice (A) and smoke-exposed mice (B and C (magnified from figure B)). CD11b expressing neutrophils (indicated with arrows in C) are present in mice exposed to cigarette smoke, whereas air exposed mice did not show an influx of these cells.
