Abstract
PURPOSE OF REVIEW: The aim of this review is to overview the pathophysiological role of adipocytokines in atherogenesis, focusing on their potential role as biomarkers of coronary disease. RECENT FINDINGS: Several lines of evidence indicated adipose tissue not only as depot but rather as an endocrine organ. In this context, the balance between pro- and anti-inflammatory adipocytokines has been shown to critically regulate vascular homeostasis in both physiological and pathophysiological conditions. Overweight and obesity are characterized by dysfunctional adipose tissue and then the prevalence of pro-inflammatory mediators, with a detrimental effect on vascular health. As opposite to adiponectin, pro-inflammatory adipocytokines, such as leptin and resistin, promote endothelial dysfunction and inflammatory processes involved in atherosclerotic plaque progression and vulnerability. Therefore, many adipocytokines have been investigated as potential biomarkers of cardiovascular (CV) risk, but their role has not yet been clearly established. Furthermore, the perivascular adipose tissue recently emerged as a critical modulator of atherosclerotic processes, due to the close interaction with the underlying vascular tissue. The ongoing discovery of new adipocytokines and the complex pathophysiological role of the different adipose tissue depots strongly contribute to define the complexity of adipocytokines network. Understanding those complex interactions may allow determining new potential biomarkers of CV risk and potential therapeutic targets.
