Nanoscale engineered exosomes for dual delivery of Sirtuin3 and insulin to ignite mitochondrial recovery in myocardial ischemia-reperfusion
{{output}}
Background: Acute myocardial infarction remains a leading cause of mortality, with ischemia-reperfusion (I/R) injury causing severe myocardial damage through mitochondrial dysfunction. While mesenchymal stem cell-derived exosomes... ...
