OBJECTIVE Antioxidative drugs continue to be developed for the treatment of atherosclerosis. Apocynin is an nicotinamide adenine dinucleotide phosphate oxidase inhibitor with anti-inflammatory properties. We used contrast-enhanced ultrasound molecular imaging to assess whether short-term apocynin therapy in atherosclerosis reduces vascular oxidative stress and endothelial activation APPROACH ...
Endothelium-derived nitric oxide (NO) and its precursor L-arginine have been implied to promote angiogenesis, but little is known about the precise mechanism. The inhibition of endogenous NO formation by Nomega-nitro-L-arginine methyl ester (L-NAME) (1 mmol/L) but not its inactive enantiomer D-NAME (1 mmol/L) inhibited endothelial cell sprouting from the scratched edge of the cultured bovine ao...
Inflammation plays a critical role in the initiation, progression, and clinical complications of atherosclerosis.1 Experimental evidence indicates that lesion formation is dependent on heterotypic interactions among immune cells, endothelial cells, and platelets. An emerging paradigm is the linkage between inflammation and thrombosis—namely, inflammation can beget thrombosis, and thrombosis can...
Growing evidence shows that adhesion molecules on sickle erythrocytes interact with vascular endothelium leading to vaso-occlusion. Erythrocyte intercellular adhesion molecule-4 (ICAM-4) binds alphaV-integrins, including alphaVbeta3 on endothelial cells. To explore the contribution of ICAM-4 to vascular pathology of sickle cell disease, we tested the effects of synthetic peptides, V(16)PFWVRMS ...
Platelet PI3Kγ Contributes to Carotid Intima-Media Thickening under Severely Reduced Flow Conditions
Studies have begun to focus on the emerging function of platelets as immune and inflammatory cells that initiate and accelerate vascular inflammation. Phosphoinositide 3-kinase gamma (PI3Kγ) is critically involved in a number of inflammatory and autoimmune diseases. This study aims to investigate the contribution of platelet PI3Kγ to vascular remodeling under flow severely reduced conditions. M...
The molecular nature of cell adhesion mediated by platelet/endothelial cell adhesion molecule 1 (PECAM-1; CD31) was examined using stably transfected L cells in a PECAM-dependent aggregation assay. This adhesion was temperature sensitive and divalent cation dependent, with Mg2+ supporting aggregation to a greater degree than Ca2+. PECAM-dependent aggregation was heterophilic: PECAM-1 transfecta...
Platelet/endothelial cell adhesion molecule 1 (PECAM-1; CD31) is crucial to the process of leukocyte transmigration through intercellular junctions of vascular endothelial cells. A monoclonal antibody to PECAM, or recombinant soluble PECAM, blocks transendothelial migration of monocytes by 70-90%. Pretreating either the monocytes or the endothelial junctions with antibody blocks transmigration....
