Soluble forms of the adhesion molecules ICAM-1, VCAM-1 and E-selectin have been detected in supernatants from cytokine activated cultured endothelial cells. The release has been quantified using two site enzyme immunoassays. The molecular weights of the released molecules have been determined by immunoprecipitation and are consistent with the generation of(More)
Levels of soluble adhesion molecules have been shown to reflect their cell surface expression in vitro, and thus may provide a useful surrogate marker of surface expression at inflammatory sites. In patients with SLE and vasculitis, serum levels of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and E-Selection were(More)
OBJECTIVE To investigate the relationship between the soluble derivatives of endothelial adhesion molecules liberated by activated vascular endothelium and the development of the systemic inflammatory response syndrome and organ dysfunction in septic patients. DESIGN Prospective cohort study with controls. SETTING University hospital intensive care(More)
Vascular cell adhesion molecule-1 (VCAM) is a cytokine-inducible member of the immunoglobulin superfamily which binds to the integrin VLA-4. VCAM is expressed predominantly on the vascular endothelium where it is involved in the recruitment of mononuclear cells and lymphocytes to sites of inflammation. Two forms of VCAM containing six and seven Ig domains(More)
Cellular adhesion molecules are crucial determinants of the migration of immune effector cells to the tissues. In chronic inflammatory diseases, upregulation of the expression of these molecules may contribute to the persistent inflammatory process. The aim of this study was to determine whether there is evidence of adhesion molecule expression in(More)
We have studied the cytokine regulation of cell surface and soluble intercellular adhesion molecule 1 (ICAM-1) expression on the human melanoma cell line A375M. Unstimulated cells express ICAM-1 on their cell surface but do not secrete significant levels of soluble ICAM-1. Interleukin 1, interleukin 6, tumor necrosis factor, and gamma-interferon all(More)
Thirty isolates of Clostridium difficile expressing different degrees of toxigenicity and virulence in an animal model were assayed for the production of chondroitin-4-sulphatase, hyaluronidase, heparinase, collagenase and protease. All strains demonstrated some hydrolytic enzyme activity. There was no direct correlation between toxigenic status, or(More)
We have demonstrated that patients with ovarian carcinoma have higher levels of soluble intercellular adhesion molecule-1 (ICAM-1) in their serum and ascitic fluids than serum from normal individuals and non-neoplastic gynaecological disease or ascites from patients with cirrhosis. In order to investigate the source of the ICAM-1, and to study the(More)
