BACKGROUND The phosphodiesterase type-5 (PDE-5) inhibitor sildenafil has been reported to improve pulmonary arterial hypertension (PAH), but the mechanisms that account for this effect are incompletely understood. Severe pulmonary hypertension has been characterized by defects in a signaling pathway involving angiopoietin-1 and the bone morphogenetic receptor-2 (BMPR-2). We investigated the eff...
INTRODUCTION In critically ill patients, the massive release of angiopoietin-2 (Ang-2) from endothelial Weibel-Palade bodies interferes with constitutive angiopoietin-1 (Ang-1)/Tie2 signaling in endothelial cells, thus leading to vascular barrier breakdown followed by leukocyte transmigration and capillary leakage. The use of circulating Ang-1 and Ang-2 as novel biomarkers of endothelial integr...
Angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2) are the two ligands of the Tie-2 receptor, a receptor tyrosine kinase that is expressed on the endothelium. A balanced angiopoietin/Tie-2 system is critical for the maintenance of vascular integrity. We investigated the potential role of a disrupted angiopoietin/Tie-2 system on hyperglycemic exacerbation of myocardial infarction and impaired ang...
BACKGROUND Angiopoietin-1 (Ang-1) is an essential mediator of angiogenesis that establishes vascular integrity, and angiopoietin-2 (Ang-2) acts as its natural inhibitor. We considered that angiopoietin might be important in bronchial asthma. METHODS In total, 35 patients with asthma and 20 healthy subjects were studied. RESULTS The serum Ang-1 levels were significantly elevated in patients ...
