Fig. 5From: The main rhinovirus respiratory tract adhesion site (ICAM-1) is upregulated in smokers and patients with chronic airflow limitation (CAL)Quantification of ICAM-1-expressing goblet cells (a-b) and submucosal glands (c-d) in the cross-sectional study. (a) ICAM-1 expressing goblet cells in large airway epithelium. (b) Intensity of ICAM-1 staining of goblet cells in large airway epithelium. Only ICAM-1 positive goblet cells are included in this comparison. (c) ICAM-1 expressing submucosal glands. (d) Intensity of ICAM-1 staining of submucosal glands. Abbreviations: NC, normal control; CAL, chronic airflow limitation; ICAM-1, intercellular adhesion molecule-1; NLFS, normal lung-function smokerBack to article page
