CD14 and coronary artery disorder: In our previous study, we found that Fc receptor III A of immunoglobulin G (FcγRIIIA, also called CD14+CD16+ monocyte subpopulation) is one of the differentially expressed genes related to coronary heart disease (CHD) patients using the oligonucleotide microarray technique [2], and high level of FcγRIIIA in CHD patients observed previously was verified by both mRNA level and its protein content [3].
