Strikingly, CCR1-expressing monocytes were significantly increased among the postoperative CAD cohort, in comparison to the preoperative CAD cohort as well as the controls, characterizing a switch from the monocyte to macrophages’ differentiation process, where CCR2 intensities are reported to decline with a substantial increase in CCR1 [60]. The gene discussed is CCR1; the disease is coronary artery disorder.
