The targeted delivery of anti-inflammatory agents has great therapeutic potential for treating restenosis following percutaneous coronary intervention. To develop a drug delivery system targeted to injured blood vessels, we examined whether N-acetylglucosamine (GlcNAc)-bearing polymer-coated liposomes (GlcNAc-Ls) are specifically taken up by vascular smooth muscle cells (VSMCs). Flow cytometric analysis revealed that GlcNAc-Ls were taken up by VSMCs in vitro. Furthermore, GlcNAc-Ls were intravenously administered to mice that had undergone wire-mediated vascular injury. GlcNAc-Ls markedly accumulated at the intramural site of the injured vessel walls but not at the contralateral (uninjured) vessel walls. These results demonstrated that GlcNAc-Ls can be specifically taken up by VSMCs both in vitro and in vivo. We propose a novel strategy of using GlcNAc-Ls that has potential for application in drug delivery targeted to injured blood vessels.
