Inflammatory cytokines in atherosclerosis: current therapeutic approaches.

The notion of atherosclerosis as a chronic inflammatory disease has intensified research on the role of cytokines and the way these molecules act and interact to initiate and sustain inflammation in the microenvironment of an atherosclerotic plaque. Cytokines are expressed by all types of cells involved in the pathogenesis of atherosclerosis, act on a variety of targets exerting multiple effects, and are largely responsible for the crosstalk among endothelial, smooth muscle cells, leucocytes, and other vascular residing cells. It is now understood that widely used drugs such as statins, aspirin, methotrexate, and colchicine act in an immunomodulatory way that may beneficially affect atherogenesis and/or cardiovascular disease progression.

The role of microRNAs in coronary artery disease: From pathophysiology to diagnosis and treatment.

MicroRNAs (miRNAs) are tiny non-coding RNA molecules that regulate gene expression predominantly at the post-transcriptional level. Far from being simple intracellular regulators, miRNAs have recently been involved in intercellular communication and have been shown to circulate in the bloodstream in stable forms. In the past years specific miRNA expression patterns have been linked to the development of atherosclerosis and coronary artery disease, two closely related conditions.

Statins as Pleiotropic Modifiers of Vascular Oxidative Stress and Inflammation.

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the industrialized world and in the future is expected to be the number one killer worldwide. The main cause underlying CVD is atherosclerosis. A key event in atherosclerosis initiation and progression is oxidative stress through the production of reactive oxygen species as well as endothelial dysfunction.

The Role and Predictive Value of Cytokines in Atherosclerosis and Coronary Artery Disease.

Atherosclerosis is currently regarded as a chronic inflammatory disease that is mediated by several types of cells and molecules. Emphasis has been placed on the role of cytokines and the way they act and interact to initiate and sustain inflammation in the microenvironment of an atherosclerotic plaque. Cytokines are invariably expressed by all cells involved in the pathogenesis of atherosclerosis, act on a variety of targets exerting multiple effects and are largely responsible for the crosstalk among endothelial, smooth muscle cells, leukocytes and other vascular residing cells.
