Selective inhibition of vascular smooth muscle cells to improve safety and efficacy of anti-restenotic therapy

總結

Coronary artery disease (CAD) is a leading cause of death in the US and throughout the world. While balloon angioplasty and/or stent implantation is a common surgical treatment, the occurrence of restenosis in these patients leads to future complications and additional surgical intervention. To this end, therapies that utilize drug-eluting stents (DES) non-selectively reduce vascular smooth muscle cell (VSMC) growth, minimizing restenosis, but also inhibit growth of vascular endothelial cells (VEC), leading to post-operative thrombosis and death. This technology describes a microRNA-based (miRNA-based) approach to prevent restenosis by inhibiting proliferative VSMCs, while selectively promoting reendothelialization and persevering VEC function. As such, this technology retains the patency maintenance required of CAD treatments while lowering the risk of post-operative thromboses, ultimately improving long-term patient outcomes.
