C-reactive protein, cytokines and inflammation in cardiovascular diseases

Inflammation of vascular cell wall is the key problem and proinflammatory cytokines and chemokines play a great role in it. These molecules, togheter with C-reactive protein (CRP) can predict risk of coronary events. It is questionable to what extend are CRP and pro-inflammatory cytokines purely acute phase markers and to what extend are they active inflammatory participants. Besides inflammation, other prominent mechanism in the pathogenesis of atherosclerosis and atherothrombosis--underlying causes of coronary events, is genetics. Gene polymorphisms including polymorphisms of inflammatory markers are studied and one of them, polymorphism of monocyte chemoattractant protein (MCP-1/CCL2) and its receptor CCR2 (key components of atherosclerosis) belong to most studied one. MCP-1/CCL2 and CCR2 polymorphisms have been implicated as susceptibility factors for chronic stable angina pectoris and myocardial infarction by several independent investigators. It seems that CCL2/CCR2 axis plays an important role both in post-ischemic and post-reperfusion inflammation and could become a new therapeutic goal in selected cardiovascular diseases as well as in stroke in future. Inhibition of this axis disrupts ischemic-reperfusion injury by decreasing edema, leucocyte infiltration and expression of inflammatory mediators. One can suppose that identifying genes influencing inflammatory biomarkers might improve understanding of genetic determinants of cardiovascular disease our management and prevention (Tab. 2, Fig. 1, Ref. 105).
