Lymphocytes bound at endothelial cell junctions extravasate within minutes. Lymphocyte-endothelial cell binding is mediated by receptors such as vascular cell adhesion molecule 1 (VCAM-1). VCAM-1 activates endothelial cell nicotinamide adenine dinucleotide phosphate (NADPH) oxidase in minutes, and this activity is required for VCAM-1–dependent lymphocyte migration. In this report, we examined m...

Circulating vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1) and selectins were prospectively measured in 145 newly-diagnosed patients with symptomatic myeloma (NDMM), 61 patients with asymptomatic/smoldering myeloma (SMM), 47 with monoclonal gammopathy of undetermined significance (MGUS) and 87 multiple myeloma (MM) patients at first relapse who received l...

As part of the inflammatory response, the localization of leukocytes depends to an important degree on cytokine-induced expression of vascular cell adhesion molecule-1 (VCAM-1) on endothelial cells (EC). We have previously shown that VCAM-1 expression is induced on human umbilical vein EC (HUVEC) by both tumor necrosis factor alpha (TNF-alpha) and interleukin-1 alpha (IL-1 alpha), whereas on hu...

Vascular cell adhesion molecule-1 (VCAM-1), a key receptor for the leukocyte-associated integrin (VLA4), is a crucial mediator of leukocyte adhesion and has co-stimulatory functions in inflammation at various organ sites. Specifically, VCAM-1/VLA4 interactions have been shown to play important roles in the setting of cutaneous immune responses, such as psoriatic lesions in humans and acute Graf...

The ability of the alpha4 integrin counterligands vascular cell adhesion molecule (VCAM)-1 or mucosal addressin (MAd)CAM-1 to support eosinophil rolling or firm adhesion under conditions of physiologic flow has not been delineated. Using a parallel plate flow chamber in vitro and intravital microscopy in vivo, we demonstrate that eosinophil rolling and adhesion on VCAM-1 is mediated by both alp...

We have demonstrated previously that cytokines induce surface expression of vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) on BEAS-2B bronchial epithelial cells in vitro. The present studies demonstrate glucocorticoid inhibition of cytokine-induced VCAM-1 expression as detected using flow cytometry and Northern blot analysis. Several commonly used inha...

Introduction: Oxidative stress is one of the inflammatory events caused by obesity. This condition characterized an increase in various markers, such as intercellular adhesion molecule 1 (ICAM-1), vascular cell (VCAM-1), and a cluster differentiation 40 (CD40). study aimed to analyze effect Plectranthus amboinicus (Lour.) Spreng ethanol extract on ICAM-1, VCAM-1, CD40 obese rats. Methods: The u...

Vascular cell adhesion molecule-1 (VCAM-1) is induced on endothelial cells by inflammatory cytokines, and binds mononuclear leukocytes through the integrin very late antigen-4 (VLA-4) (alpha 4 beta 1). This adhesion pathway has been implicated in a diverse group of physiological and pathological processes, including B cell development, leukocyte activation and recruitment to sites of inflammati...

Tumor necrosis factor (TNF) and interleukin 1 are known to initiate endothelial vascular cell adhesion molecule (VCAM)-1 transcription primarily by activating nuclear factor (NF)-kappaB, which translocates to the nucleus. In addition to two NF-kappaB elements found within the minimal cytokine-inducible VCAM-1 promoter, an interferon-related factor (IRF) element (IRF-1) has been identified close...

Vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), and E-selectin are inducible proteins involved in cell-cell adhesion. Immunohistochemical studies have indicated that human atherosclerotic plaques contain smooth muscle cells (SMCs) that express ICAM-1 and VCAM-1. Recently, we demonstrated that SMCs in culture express a functionally active cytokine-inducibl...
