The early effects of hypercholesterolemia on leukocyte-endothelium interaction were studied in vivo in the rabbit mesenteric microcirculation. Rabbits fed a 0.5% high-cholesterol (HC) diet showed elevated plasma cholesterol levels during the 1 to 2 weeks of HC feeding (P<0.001 versus control diet-fed rabbits). Intravital microscopy of mesenteric venules revealed that leukocyte rolling had incre...

The levels of the eicosanoids leukotriene B4, prostaglandin E2, prostacycline and thromboxane B2, the cytokines interleukin-1 beta, interleukin-6 and tumour necrosis factor-alpha and soluble intercellular adhesion molecule 1 were measured in ascites and plasma samples of patients with liver cirrhosis (53), peritoneal cancer (26) and spontaneous bacterial peritonitis (10) to assess their value a...

Leukocyte transmigration into the central nervous system promotes multiple sclerosis pathogenesis, yet ambiguity remains regarding the mechanisms controlling the migration of distinct immune cell subsets. Using in vitro, ex vivo and postmortem human materials, we identified a significant upregulation of junctional adhesion molecule-like expression at the blood-brain barrier, monocytes, and CD8 ...

Sasaki, Makoto, John W. Elrod, Paul Jordan, Makoto Itoh, Takashi Joh, Alireza Minagar, and J. Steven Alexander. CYP450 dietary inhibitors attenuate TNF-stimulated endothelial molecule expression and leukocyte adhesion. Am J Physiol Cell Physiol 286: C931–C939, 2004; 10.1152/ajpcell.00351.2003.—Enhanced expression of mucosal addressin cell adhesion molecule-1 (MAdCAM-1) and other endothelial cel...

Combination of microbial assays and Single Molecule Force Spectroscopy evidence nano–macro relationship in adhesion properties ofE. coliexpressing Yad fimbriae. Affinity fimbriae for xylose is as strong that YadC YadN antibodies.

OBJECTIVE Expression of adhesion molecule receptors on venous endothelial cells crucially influences the fate of venous grafts by mediating leukocyte-endothelium interactions. These interactions include adhesion of leukocytes to the endothelium, followed by transendothelial migration, leading to neointimal hyperplasia (NIH) and finally graft occlusion. Therefore, inhibition of adhesion molecule...

OBJECTIVE To appreciate the evolution of serum angiogenic and/or adhesion molecules levels during a long term follow-up of rheumatoid arthritis (RA) patients. METHODS Serum levels of 5 soluble adhesion/angiogenesis glycoproteins (VEGF, CD31, CD54, CD62E, CD106) were measured in Elisa in samples collected over 6 years in a cohort of 43 RA patients with monitored clinical parameters of disease ...

atherosclerosis is a chronic inflammatory condition. many pro-inflammatory factors including interleukin-6 (il-6), tumor necrosis factor-α (tnf-α), c-reactive protein (crp), and adhesion molecules including intercellular adhesion molecule (icam-1) and vascular cell adhesion molecule (vcam-1) are expressed in atherosclerotic lesions. the plants of genus vaccinium are rich in anthocyanins with an...

Cocaine treatment of mice with viral myocarditis significantly increases neutrophil infiltration into the myocardium and exacerbates the inflammatory response. The mechanisms of these effects are unknown; however, it may be that cocaine increases circulating catecholamines and consequently increases inflammatory cell adhesion to the coronary endothelium. Here, we examined the hypothesis that co...

Leukocyte adhesion contributes to perfusion abnormalities and tissue damage during trauma, shock or overwhelming inflammation. This study was performed to determine whether the lipoxygenase inhibitor phenidone and derivatives decrease the expression of adhesion molecules on tumor necrosis factor-alpha (TNF-alpha) stimulated endothelial cells and attenuate leukocyte-endothelial interactions unde...
