Intercellular Adhesion Molecule-1 Deficiency

A Comparative Study of Serum Level of Vascular Cell Adhesion Molecule-1 (sVCAM-1), Intercellular Adhesion Molecule-1(ICAM-1) and High Sensitive C - reactive protein (hs-CRP) in Normal and Pre-eclamptic Pregnancies

Glutathione peroxidase-1 deficiency augments proinflammatory cytokine-induced redox signaling and human endothelial cell activation.

Glutathione peroxidase-1 (GPx-1) is a crucial antioxidant enzyme, the deficiency of which promotes atherogenesis. Accordingly, we examined the mechanisms by which GPx-1 deficiency enhances endothelial cell activation and inflammation. In human microvascular endothelial cells, we found that GPx-1 deficiency augments intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1...

Protein kinase C upregulates intercellular adhesion molecule-1 and leukocyte-endothelium interactions in hyperglycemia via activation of endothelial expressed calpain.

OBJECTIVE We tested the hypothesis of a role for the calcium-dependent protease calpain in the endothelial dysfunction induced by hyperglycemic activation of protein kinase C (PKC). METHODS AND RESULTS Chronic hyperglycemia with insulin deficiency (type 1 diabetes) was induced in rats by streptozotocin. Total PKC and calpain activities, along with activity and expression level of the 2 endoth...

Tumor necrosis factor alpha induces adhesion molecule expression on human fetal astrocytes

Leukocyte adhesion molecules on endothelial cells of the blood-brain barrier may participate in the entry of leukocytes into the central nervous system. Because astrocytes are also a component of the blood-brain barrier and have been associated with inflammation, we studied the ability of astrocytes to express leukocyte adhesion molecules using Northern blot and immunocytochemical techniques. A...

اثر یک دوره تمرین هوازی بر شاخص‌های عملکرد اندوتلیالی زنان یائسه مبتلا به پرفشار خونی

    Background & Aims : Aging and the loss of endogenous estrogen production after menopause are accompanied by increases in blood pressure and endothelial dysfunction. Exercise training improves endothelial function in patients with hypertension. The aim of this study was to examine the effect of aerobic training on some markers of endothelial function in hypertensive postmenopausal women.   M...

Protease-Activated Receptor-2 Deficiency Attenuates Atherosclerotic Lesion Progression and Instability in Apolipoprotein E-Deficient Mice

Inflammatory mechanisms are involved in the process of atherosclerotic plaque formation and rupture. Accumulating evidence suggests that protease-activated receptor (PAR)-2 contributes to the pathophysiology of chronic inflammation on the vasculature. To directly examine the role of PAR-2 in atherosclerosis, we generated apolipoprotein E/PAR-2 double-deficient mice. Mice were fed with high-fat ...
