| Outline of Final Research Achievements |
Objective of our study is to build up a new method for management of post-angioplasty restenosis using liposomes, whose surface was decorated with sialyl Lewis X (SLX). Drug delivery is controlled with the affinity between SLX and E-selectin proteins, which are expressed on vessel walls after angioplasty and promote restenosis. Main theme of this task is visualization of E-selectin positive lesion on MRI. Gd-liposome SLX, which is liposome including gadolinium (Gd) with SLX decoration was used for E-selectin targeting. In vivo experiments confirmed accumulation of Gd matched with E-selectin positive lesions after angioplasty.
