Our analysis on the expression of chemokine and its receptor genes in MI samples showed that chemokines CCL3, CXCL3, CXCL8, and CXCL16 were highly expressed in CD1C-CD141- dendritic cells and that CCL4 and CCL5 were highly expressed in natural killer cells. This evidence concerns the gene CCL3 and myocardial infarction.
