Vascular restenosis reduction with platelet membrane coated nanoparticle directed M2 macrophage polarization

ABSTRACT: Summary Vascular restenosis is the main factor affecting the prognosis of angioplasty in cardiovascular diseases, and inflammation is a central link in the progression of restenosis. Previous research that applies interleukin 10 (IL10) nanoparticles can effectively regulate local inflammation, but their targeted delivery efficacy remains to be improved. In this study, IL10 nanoparticles were successfully prepared and then coated by a preactive platelet membrane. The ability to target and regulate macrophage polarization has been demonstrated, thereby regulating smooth muscle cell and endothelial cell functions. In vivo experiments were carried out in a carotid artery injury model and verified the above functions and the effect on inhibiting vascular restenosis. Immune regulation-based plat
