ICAM1 and atherosclerosis: Since the interaction between endothelial cells and monocytes or monocyte-derived cells is mediated through adhesion molecules [39, 40] and the upregulation of these molecules is intimately associated with atherosclerosis-prone aortas [39, 40], we examined the effect of ZNE on the expression of two molecules of this family, namely, ICAM-1 and VCAM-1.
