Abstract Background Endothelial dysfunction promotes atherogenesis, vascular inflammation, and thrombus formation. Reendothelialization after angioplasty is required in order to prevent stent failure. Previous studies have highlighted the role of 2-arachidonoylglycerol (2-AG) in murine experimental atherogenesis and in human coronary artery disease. However, the impact of 2-AG on endothelial repair and leukocyte–endothelial cell adhesion is still unknown. Methods Endothelial repair was studied i...

Recent evidence suggests that endocannabinoids acting via cannabinoid CB1 receptors may modulate vascular responses of various vasoconstrictors in the rodent systemic vasculature. The aim of the study was to investigate whether endocannabinoids modulate the contractile responses evoked by a thromboxane A2 analog (U46619), angiotensin II (ANG II), serotonin (5-HT), and phenylephrine, which stimulate distinct Gq/11 protein-coupled receptors (thromboxane, ANG II type 1, 5-HT2, and α1-adrenergic rec...
Abstract Accumulated evidence points to a key role for endocannabinoids in cell migration, and here we sought to characterize the role of these substances in early events that modulate communication between endothelial cells and leukocytes. We found that 2-arachidonoylglycerol (2-AG) was able to initiate and complete the leukocyte adhesion cascade, by modulating the expression of selectins. A short exposure of primary human umbilical vein endothelial cells (HUVECs) to 2-AG was sufficient to prim...

Background and purpose: Impaired endothelial activity and/or cell death play a critical role in the development of vascular dysfunction associated with congestive heart failure, diabetic complications, hypertension, coronary artery disease and atherosclerosis. Increasing evidence suggests that cannabinoid 1 (CB1) receptor inhibition is beneficial in atherosclerosis and cardiovascular inflammation both in experimental models, as well as in humans. Here, we investigated the effects of CB1 receptor...
