Relative to sham control mice, PBS‐treated MI model animals presented with a significant increase in the CD68+/iNOS+ macrophage ratio in the infarcted area (Figure 5J,L), together with substantially enhanced IL‐1β (Figure 5M), TNF‐α (Figure 5N), and IL‐10 secretion (Figure 5O). This evidence concerns the gene IL10 and myocardial infarction.
