BACKGROUND Studies have suggested that soluble factors in plasma from patients with active (aBD) and inactive (iBD) Behçet's disease (BD) stimulate neutrophil function. Soluble CD40 ligand (sCD40L) is an important mediator of inflammation in BD. Its expression and effect on neutrophil oxidative burst and neutrophil extracellular trap (NET) release have not been characterized. In this study, we ...

The proinflammatory and proatherogenic mediator, soluble CD40 ligand (CD40L), is increased in the metabolic syndrome (MS) and released from platelets. We hypothesized that adiponectin modulates platelet function, and we sought to evaluate the association of adiponectin and sCD40L levels with platelet aggregation in MS and the effects of adiponectin on platelet aggregation and activation. Platel...

Platelet activation and thrombin generation are crucial steps in primary and secondary haemostasis. However, both also play major roles in intravascular thrombus formation and therefore in the development of adverse cardiovascular events. In the current study, we first sought to investigate the associations of the platelet biomarkers platelet factor (PF)-4, thrombospondin (TSP)-1, soluble CD40 ...

Systemic markers of inflammation may be increased in patients after percutaneous coronary intervention. In the present study, we evaluated whether IP (ischaemic preconditioning) attenuated inflammation by activating KATP (ATP-sensitive potassium) channels in patients undergoing coronary angioplasty. Patients (n=36) undergoing angioplasty of a major left coronary artery were allocated randomly t...

AIMS We investigated the prognostic performance of myeloperoxidase (MPO), and soluble CD40 ligand (sCD40L) along with B-type natriuretic peptide (BNP), high-sensitivity C-reactive protein (hsCRP), and cardiac troponin I (cTnI) for non-fatal recurrent ischaemic events in non-ST elevation acute coronary syndrome (ACS). METHODS AND RESULTS We measured plasma MPO and sCD40L in 1524 patients with ...

BACKGROUND Increased expression of CD40L has been reported on activated CD4+ T lymphocytes in systemic sclerosis. CD40L can be expressed in soluble form (sCD40L). OBJECTIVE To compare sCD40L concentrations in patients with systemic sclerosis and healthy controls. METHODS Quantitative sandwich ELISA was used to measure plasma sCD40L in systemic sclerosis (n = 50) and matched healthy controls...

BACKGROUND Interaction of CD40L with its receptor CD40 is critically involved in inflammatory cell activation in atherogenesis. In addition, serum levels of soluble CD40L are elevated in acute coronary syndromes and have been associated with increased cardiovascular risk in healthy subjects, thus making sCD40L an intriguing target to modulate the inflammatory response in the vasculature. PPARga...

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...

To maintain tolerance, autoreactive B cells must regulate signal transduction from the BCR and TLRs. We recently identified that dendritic cells and macrophages regulate autoreactive cells during TLR4 activation by releasing IL-6 and soluble CD40 ligand (sCD40L). These cytokines selectively repress Ab secretion from autoreactive, but not antigenically naive, B cells. How IL-6 and sCD40L repress...

CD40/CD40 ligand (CD40L) dyad, a co-stimulatory bi-molecular complex involved in the adaptive immune response, has also potent pro-inflammatory actions in haematopoietic and non-haematopoietic cells. We describe here a novel role for soluble CD40L (sCD40L) as modifier of glomerular permselectivity directly acting on glomerular epithelial cells (GECs). We found that stimulation of CD40, constitu...
