Figure 3From: Adhesion molecules in subjects with COPD and healthy non-smokers: a cross sectional parallel group studySoluble adhesion molecules in serum. Levels of soluble adhesion molecules A) ICAM-1, B) ICAM-3, C) PECAM-1, D) VCAM-1, E) E-selectin and F) P-selectin measured in serum from controls (n=12), smokers without COPD (n=12) and smokers with COPD (n=12). Soluble adhesion molecules were measured in subjects where samples from all compartments (blood, sputum and BAL) were available. Results are presented as ng/mL. P-values indicate comparisons between groups.Back to article page
