AIMS To assess the association between circulating levels of soluble CD40 ligand (sCD40L), an emerging cardiovascular risk factor, and gamma-glutamyltransferase (GGT) activity concentrations in Type 1 diabetic subjects. METHODS Plasma concentrations of sCD40L and GGT activity, a marker of liver dysfunction, were measured in 54 non-smoking, non-drinking, young Type 1 diabetic patients, who wer...

OBJECTIVE Soluble CD40 ligand (sCD40L) has been recently implicated in the pathogenesis of atherosclerosis. Elevated levels of sCD40L in acute coronary syndrome patients suggests enhanced platelet function; however, the exact mechanism by which this occurs is unknown. In this study, we examined the effect of sCD40L on platelet function and reactive oxygen and nitrogen species (RONS) generation....

Background: Primary malignant bone tumors are heterogeneous groups of neoplasms, which affect mainly children and adolescents. The most common types are Osteosarcoma, Ewing sarcoma and chondrosarcoma. Elevation of sCD30 and sCD40L has been observed in lymphoma, leukemia and autoimmune disorders. Objective: To evaluate serum concentrations of sCD30 and sCD40L in patients with primary malignant b...

Background: The CD40/CD40L system, a key regulator and amplifier of immune reactivity, is activated in inflammatory bowel disease (IBD) mucosa. Aims: To determine whether plasma levels of sCD40L are elevated in Crohn’s disease (CD) and ulcerative colitis (UC) patients compared with normal controls, to investigate the cellular source of sCD40L, and to explore CD40L induction mechanisms. Patients...

BACKGROUND This study tested the hypothesis that in the acute phase of myocardial infarction (MI), the circulating level of soluble CD40 ligand (sCD40L), an index of platelet activation, is predictive of angiographic morphologic features that indicate high-burden thrombus formation (HBTF) in the infarct-related artery (IRA). METHODS AND RESULTS This prospective study included 162 consecutive ...

The role of endothelial progenitor cells in vascular repair is related to their incorporation at sites of vascular lesions, differentiation into endothelial cells, and release of various angiogenic factors specifically by a subset of early outgrowth endothelial progenitor cells (EOCs). It has been shown that patients suffering from cardiovascular disease exhibit increased levels of circulating ...

OBJECTIVES The aim of this research was to evaluate the effect of genetic polymorphisms C807T and G1648A of platelet glycoprotein Ia (GPIa), on the risk for myocardial infarction (MI) and on the release of soluble CD40 ligand (sCD40L) during the acute phase of MI and one year after the event. BACKGROUND C807T and G1648A polymorphisms affect the density of GPIa on platelet surface, but their e...

OBJECTIVES In the present study, we investigated the effects of statins on serum levels of soluble CD40 ligand (sCD40L) in patients with familial hypercholesterolemia (FH). BACKGROUND Atherosclerotic disease seems to involve inflammatory and immunologic mechanisms, and sCD40L has recently been identified as one of the key players in the atherosclerotic process. HMG-Co A reductase inhibitors, ...

The study's objective was to evaluate the clinical significance of sCD40L in HCV- associated hepatocellular carcinoma (HCV-HCC) patients. Sera concentration of circulating sCD40L and IL-10 were assayed using ELISA in 30 HCVpositive patients with HCC, 30 HCV-positive patients with liver cirrhosis and 30 age-matched healthy volunteers with negative anti-HCV-Ab as a control group. Serum sCD40Lshow...
