Endothelial cells and macrophages, partners in atherosclerotic plaque progression.
Heart disease and stroke, the main cardiovascular diseases (CVD), have become global epidemics in our days. High levels of cholesterol and other abnormal lipids are among the main risk factors of atherosclerosis, the number one killer in the world. However, recent advances in CVD treatment together with improvements in surgical techniques have increased the quality of life and reduced premature death rates and disabilities. Nevertheless, they still add a heavy burden to the rising global costs of health care. The medical priorities highlight not only the need for early recognition of the warning signs of a heart attack, but also the need for early biomarkers for prevention. Two active partners in the development and progression of atherosclerotic plaques are the macrophages and endothelial cells that influence each other and modify the microenvironment composition of the plaque leading to either rapid progression or regression of individual lesions in patients. In this review we address two specific aspects related to atherosclerosis: i) the way in which folic acid and folic acid conjugates may be helpful to identify activated macrophages and ii) the high potential of proteomic analysis to evidence and identify the multiple changes induced in activated vascular cells.
