In our study, the ratio of apoptotic macrophages in total macrophages in the infarcted myocardium was significantly higher in AIM‒/‒ mice than in WT mice at 3 days after MI, whereas there was no significant difference in the expression of MCP-1 in the infarcted myocardium at 3 days after MI between WT and AIM‒/‒ mice. Here, CCL2 is linked to myocardial infarction.
