Stromal-platelet membrane-inspired nanoparticles (SPIN) for targeted heart repair.

ABSTRACT: Myocardial infarction (MI), commonly known as a heart attack, remains a leading cause of death worldwide. Standard treatments, such as coronary stent placement or coronary artery bypass graft surgery, aim to restore blood flow to ischemic myocardial tissue. However, a significant complication of these procedures is ischemia/reperfusion (I/R) injury, which occurs when blood flow is restored, triggering oxidative stress, inflammation, and calcium overload that can further damage the heart. To limit the I/R injury following the coronary recanalization of an MI heart, we designed stromal-platelet membrane-inspired nanoparticles (SPINs) that consist of a poly (lactic-co-glycolic acid) (PLGA) core, decorated by a dual membrane coating: a platelet membrane for precise adhesion to the damaged endo
