BACKGROUND Diabetes, depression and aging have been associated with pro-inflammatory and prothrombotic state. AIM The aim of the study was to determine the plasma levels of thrombomodulin, plasminogen activator inhibitor-1 (PAI-1) and fibrinogen in elderly diabetic patients with and without depressive symptoms and to examine factors (including thrombomodulin, PAI-1, fibrinogen levels) associa...

BACKGROUND Endothelial dysfunction plays an important role in the pathophysiology of sepsis. As previously reported, the serum thrombomodulin is elevated in diseases associated with endothelial injury. OBJECTIVE The aim of this study was to investigate the association of serum thrombomodulin level in different pediatric sepsis syndromes and evaluate the relationship with disease severity and ...

Annexin-V (PAP-I, lipocortin-V) acts as a potent anticoagulant in vitro by binding to negatively charged phospholipids with higher affinity than vitamin K-dependent proteins, with a Kd in the 10(-10) M range. The purpose of the present study was to use annexin-V as a probe to assess the catalytic potential of phospholipids in pro- and anti-coagulant reactions in purified systems and at the surf...

INTRODUCTION Thrombomodulin, which is expressed solely on monocytes, along with tissue factor (TF), takes part in coagulation and inflammation. Circulating blood monocytes can be divided into 3 major subtypes on the basis of their receptor phenotype: classical (CD14brightCD16negative, CMs), inflammatory (CD14brightCD16positive; IMs), and dendritic cell-like (CD14dimCD16positive DMs). Monocyte s...

The present study was designed to test the hypothesis that circulating levels of thrombomodulin are elevated in patients with hypertension in proportion to the severity of the vascular damage. A cross-sectional study was carried out using a population consisting of 96 patients with essential hypertension without clinically evident cardiovascular disease (mean age: 65 +/- 10 years) and 99 health...

The influence of phospholipid on thrombin-thrombomodulin-catalyzed activation of protein C has been studied by incorporating thrombomodulin into vesicles by dialysis from octyl glucoside-phospholipid mixtures. Thrombomodulin was incorporated into vesicles ranging from neutral (100% phosphatidylcholine) to highly charged (30% phosphatidylserine and 70% phosphatidylcholine). Thrombomodulin is ran...

The domain of thrombomodulin that binds to the anion-binding exosite of thrombin was identified by comparing the binding of fragments of thrombomodulin to thrombin with that of Hirugen, a 12-residue peptide of hirudin that is known to bind to the anion-binding exosite of thrombin. Three soluble fragments of thrombomodulin, containing (i) the six repeated growth factor-like domains of thrombomod...

Thromboembolic syndrome is the most dangerous complication of atrial fibrillation which develops in about 8-15% cases, thus presuming role persisting left-heart thrombosis presence anticoagulant therapy some patients. When activated, blood platelets express multiple copies CD40L on their membrane. Hence, soluble form CD40 ligand considered a marker platelet activation and pathogenic processes a...

Endothelial thrombomodulin plays a critical role in hemostasis by binding thrombin and subsequently converting protein C to its active form, a powerful anticoagulant. Thrombomodulin thus represents a central mechanism by which patency is maintained in normal vessels. However, thrombomodulin expression decreases in perturbed endothelial cells, predisposing to thrombotic occlusion. An adenoviral ...
