ICAM1 and atherosclerosis: Additionally, resistin increases circulating monocyte adhesion to endothelial cells in atherogenic processes by inducing intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) expression in human umbilical vein endothelial cells, which is a critical step in the early stages of atherosclerosis [7].
