CD80 and myocardial infarction: In our rat model, DCs specific marker CD1a and CD80 double fluorescent staining was used to study the increase of aggregation and adhesion of CD1a+CD80+ cells to myocardium during MI/RI (Figure 2A), which was consistent with the increase in the expression of ICAM‐1, E‐Selectin, and P‐Selectin (Figure 2D‐G).
