Urokinase receptor surface expression regulates monocyte adhesion in acute myocardial infarction
The urokinase receptor (urokinase plasminogen activator receptor; uPAR) regulates monocyte adhesion by direct binding to vitronectin and by forming complexes with integrins. Therefore, possible up-regulation of uPAR in acute myocardial infarction (AMI) may affect monocyte adhesion. In 20 patients with AMI, uPAR surface expression (measured by flow cytometry) was increased compared with that in patients with chronic stable angina (mean ± SD fluorescence, 179 ± 96 vs 80 ± 53; P = .002)....[Show more]
