We compared U-937 cell adhesion and adhesion molecule expression in human umbilical venous (HUVECs) and arterial (HUAECs) endothelial cells exposed to tumor necrosis factor (TNF), interleukin-1, and lipopolysaccharide (LPS). TNF and LPS stimulated vascular cell adhesion molecule (VCAM)-1 surface expression and adhesion of U-937 monocyte-like cells to HUVECs but not to HUAECs. Antibody studies d...
While the levels of serum vascular cell adhesion molecule-1 (VCAM-1) have been investigated in many diseases, they have not, to our knowledge, been studied in patients with measles. Serum VCAM-1 and creatinine levels were determined in six adolescent and adult Japanese patients with measles in the acute febrile phase and defervescent afebrile phase. Serum VCAM-1 levels were significantly higher...
trans-fatty acids (tfa) are known as a risk factor for coronary artery diseases. trans-11 vaccenic acid [va; 18:1(n-9)], known as the major trans fatty acid in milk fat, is a positional and geometric isomer of oleic acid and a precursor of conjugated linoleic acid (cla) in human . this study was carried out in order to investigate the effect of cis and trans vaccenic acids on expression of intr...
plasma levels of adhesion molecule and lipid profile have emerged as an important indicator of risk for cardiovascular diseases. the aim of the study was to evaluate the effects of regular physical activity on cardiovascular markers (icam-1, vcam-1) in sedentary obese men. eighteen young sedentary obeses males (mean and sd of age, weight and bmi were respectively as follows: 20.1? 0.97 years, 9...
We herein tested the ability of lymphocytes to utilize the beta 1 integrin VLA-4 to mediate cell migration when adhering to its cytokine-inducible endothelial cell ligand VCAM-1 or its extracellular matrix ligand fibronectin. We used an in vitro system consisting of purified VCAM-1/Fc fusion protein or fibronectin immobilized on porous polycarbonate membranes to quantitatively measure the migra...
Interaction of the vascular cell adhesion molecule (VCAM-1) with its counter-receptor very late antigen-4 (VLA-4) (integrin alpha 4 beta 1) is important for a number of developmental pathways and inflammatory functions. We are investigating the molecular mechanism of this binding, in the interest of developing new anti-inflammatory drugs that block it. In a previous report, we showed that the p...
BACKGROUND A recent study showed that the level of soluble Vascular Cell Adhesion Molecule 1 (VCAM-1) emerged as a strong and independent predictor of the risk of hip and knee joint replacement due to severe osteoarthritis (OA). Therefore, we hypothesized that soluble VCAM-1 level can be associated with prevalence and severity of radiographic hand OA. OBJECTIVES To evaluate the association be...
This study aimed to investigate the function and signaling pathway of Toll-like receptor 4 (TLR4) in oxidized low-density lipoprotein (oxLDL)-induced up-regulated expressions of oxidized LDL receptor 1 (LOX-1), monocyte chemoattractant protein 1 (MCP-1), and vascular cell adhesion molecule 1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs). HUVECs were incubated with different oxLDL ...
Splenic myelopoiesis provides a steady flow of leukocytes to inflamed tissues, and leukocytosis correlates with cardiovascular mortality. Yet regulation of hematopoietic stem cell (HSC) activity in the spleen is incompletely understood. Here, we show that red pulp vascular cell adhesion molecule 1 (VCAM-1)(+) macrophages are essential to extramedullary myelopoiesis because these macrophages use...
Eosinophils are a major component of the inflammatory response in persistent airway inflammation in asthma. The factors that determine the retention of eosinophils in the airway remain poorly understood. Elevated levels of fibronectin have been observed in the airway of patients with asthma, and the levels correlate with eosinophil numbers. To determine if fibronectin density modulates eosinoph...
