IFNA1 and myocardial infarction: These subsets included Lyve1hi and Mhc-IIhi steady-state macrophages, pro-inflammatory monocytes and macrophages identified 1 and 3 days post-MI (Early-Mφs), macrophages identified 5 and 7 days post-MI (Late-Mφs) as well as several minor populations (non-classical monocytes, IFN-Mφs, and proliferating-Mφs); they were enriched in the infarcted area at different time-points after MI.
