In contrast, eight weeks after MI-R a non-significant decreased number of infiltrated CD45+ leukocytes was observed in the infarct area of the HC-MI group as compared to the NC-MI group (4.7±0.4 vs. 7.0±2.0 cells per 0.25mm2, P = 0.27, Fig 5C) whereas the number of macrophages was significantly reduced (7.9±1.8 vs. 20.7±5.4 cells per 0.25mm2, P = 0.049, Fig 5D). Here, PTPRC is linked to myocardial infarction.
