Expression of Monocyte Chemotactic Protein-1 and Its Receptor in Sudden Coro-nary Death / 法医学杂志

Objective To investigate the expression of m onocyte chem otactic protein-1 (MCP-1) and its receptor CCchem okine receptor-2 (CCR-2) in coronary atherosclerosis plaques betw een sudden coro-nary death (SCD ) and non-SCD. Methods The expression levels of MCP-1 and CCR-2 in SCD group, coronary atherosclerosis group (non-SCD), control group (norm al coronary artery) w ere detected by im-m unohistochem istry. Results Positive rates of MCP-1 am ong the three groups w ere 78%, 47%, and 0%, respectively, w ith significant expressing differences betw een each tw o groups (P0.05). Conclusion O verexpression of MCP-1 and CCR-2 in coronary atherosclerotic plaques is closely correlated w ith SCD .
