Elevated soluble CD40 ligand is related to the endothelial adhesion molecules in patients with acute coronary syndrome
Abstract
Increasing evidence indicates that the CD40-CD40L interaction plays a pivotal role in the inflammatory regulation of atherosclerosis. Adhesion molecules especially the vascular adhesion molecules also play an important role in the pathogenesis of atherosclerosis which act as markers of inflammation. These inflammatory factors render vulnerability to the atherosclerotic plaque by triggering the fissure, rupture, and subsequent thrombosis, leading to the clinical scenario of unstable angina and acute myocardial infarction. The difference of sCD40L concentration in different subtype of coronary heart disease and its relationship with vascular adhesion molecules was investigated. Enzyme-linked Immunosorbent Assay (EIA) was used to measure the serum sCD40L, soluble intercellular adhesion molecule-1 (sICAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1). The sCD40L concentration was significantly higher in patients with acute coronary syndrome (ACS) (3.17+/-2.84 ng/ml) than in controls (1.19+/-1.05 ng/ml, p<0.01) and in patients with stable coronary heart disease (1.61+/-1.46 ng/ml, p<0.05). The sCD40L concentration was positively correlated with sICAM-1 (r=0.413, p<0.01), triglycerides (TG) (r=0.23, p<0.05), apoB (r=0.24...Continue Reading

Cell Adhesion Molecules in AS
Cell adhesion molecules expressed on the vascular endothelium and circulating leukocytes in response to inflammatory stimuli are implicated in atherosclerosis. Here is the latest research.
Adhesion Molecules in Health and Disease
Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
