Colden-Stanfield, Margaret, and Mary Scanlon. VCAM-1-induced inwardly rectifying K current enhances Ca entry in human THP-1 monocytes. Am J Physiol Cell Physiol 279: C488–C494, 2000.—Hyperpolarization in human leukemia THP-1 monocytes adherent to vascular cell adhesion molecule (VCAM)-1 is due to an induction of inwardly rectifying K currents (Iir) (Colden-Stanfield M and Gallin EK, Am J Physio...

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...

VCAM-1 and ICAM-1 are endothelial adhesion molecules of the Ig gene superfamily that may participate in atherogenesis by promoting monocyte accumulation in the arterial intima. Both are expressed in regions predisposed to atherosclerosis and at the periphery of established lesions, while ICAM-1 is also expressed more broadly. To evaluate functions of VCAM-1 in chronic disease, we disrupted its ...

To determine whether nuclear factor (NF)-kB is necessary to confer endothelial cell responsiveness to interferon (INF)-g in terms of vascular cell adhesion molecule (VCAM)-1 expression and leukocyte adhesion, human endothelial cells were treated with IFN-g in the presence of low concentrations (LCs) of interleukin (IL)-1a (#100 pg/mL), which activates NF-kB but does not induce VCAM-1 expression...

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...

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...

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...

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...

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 ...

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...
