Significance
Recent studies have shown that ferroptosis is an important mechanism of myocardial ischemia-reperfusion injury (MI/RI). Therefore, simultaneous inhibition of ferroptosis and apoptosis of cardiomyocytes can be a promising strategy to treat MI/RI. Apoferritin, as a delivery carrier, can actively target to ischemic myocardium through binding with highly expressed transferrin receptor on ischemic cardiomyocytes. At the same time, apoferritin plays a protective role on ischemic cardiomyocytes by inhibiting ferroptosis. This strategy of killing two birds with one stone significantly improves the therapeutic effect on MI/RI while does not need more pharmaceutical excipients, which has the prospect of clinical transformation.
