Pathol Res Pract. 2008 Jul 16; Authors: Herwig MC, Müller KM, Müller AM Cell adhesion molecule vascular endothelial cadherin (VE-cadherin) is the major component of endothelial adherence junctions, maintaining endothelial cell integrity. Studies dealing with constitutive VE-cadherin expression patterns in different pulmonary vessel types (arteries, arterioles, capillaries, venules, veins) or with the influence of physiological factors such as age or sex on VE-cadherin expression have not been published yet. Knowledge of constitutive resp. varying expression patterns not only fundamentally contribute to understanding the role of VE-cadherin in the pathogenesis of pulmonary diseases but also help to develop therapies based on immunotargeting. Hence, endothelial VE-cadherin expression was studied in regular lung tissue. Fifty-eight specimens of regular lung tissue (30 females, 28 males between 1 month and 75 years old) were immunohistochemically stained with an antibody against VE-cadherin. There was strong endothelial expression of VE-cadherin in arteries, arterioles, and capillaries but almost no expression in veins and venules. Neither age nor sex had any influence on the expression pattern or staining intensity. There is a vessel type-specific expression pattern for VE-cadherin in regular human lung tissue, which is not influenced by age or sex. Further studies will h ...
