Further, upon classifying these monocytes into classical (M1), intermediate (M2), and non-classical subsets (M3), based on the intensities of cell surface markers CD14 and CD16 (Figure S1B), we observed a significant decrease in the frequencies of classical monocytes among postoperative CAD patients when compared with older controls (Figure 1B), whereas the differences in monocyte subsets were not evident between the preoperative CAD patients and control groups (Figure 1A). The gene discussed is CD14; the disease is coronary artery disorder.
