Interleukin 4 (IL-4), IL-10 and IL-13 are all known to modulate several proinflammatory functions in human monocytes. They have also previously been shown to down-regulate lipopolysaccharide (LPS)-induced tissue factor (TF) expression in isolated cultured monocytes. In this study we investigated the effect of these three cytokines on the induction of(More)
CONTEXT Inflammatory activity is associated with high rates of long-term mortality in unstable coronary artery disease (CAD). Interleukin 6 (IL-6) induces C-reactive protein and fibrinogen, systemic markers of inflammation. OBJECTIVES To determine whether plasma levels of IL-6 are predictive of mortality and to evaluate the interaction of IL-6 levels with(More)
Activated platelets can express CD40 ligand (CD40L) and trigger inflammatory response and tissue factor (TF) expression in endothelial cells through interaction with CD40. This pathway is also important for T cell-induced monocyte and endothelial cell procoagulant activity. We have studied the potential role of the CD40-CD40L pathway in platelet-induced TF(More)
Here we report a highly sensitive and convenient ligand binding assay for the determination of 1,25(OH)2D3 in small volumes of human plasma. This method involves: (1) extraction of vitamin D3 and its metabolites using methanol-methylene chloride with separation of phases by centrifugation; (2) gel chromatography and high pressure liquid chromatography for(More)
INTRODUCTION Mounting evidence implies beneficial properties of statins and angiotensin converting enzyme (ACE)-inhibitors beyond those of their original indications in the treatment of coronary artery disease (CAD). Less is known of the mechanisms by which low-molecular-weight (LMW) heparin, also used in unstable CAD, affects the cellular(More)
We investigated in some detail the immunologic and procoagulant activation patterns in men and women with unstable (UA, n=26) versus stable (SA, n=40) coronary artery disease (CAD). Leukocyte activation and platelet-leukocyte complex formation were assessed by flow cytometry. Plasma markers of coagulation and inflammation were analyzed. Unstable patients(More)
