CCR2 and myocardial infarction: Furthermore, studies have shown that the expression of type I interferon-stimulated genes in resident CCR2-macrophages after myocardial injury is significantly different compared with recruited CCR2+ macrophages, suggesting that CCR2-resident macrophages are responsible for the production of myocardial infarction during myocardial infarction (Calcagno et al., 2020).
