Development of¹¹¹In-Labeled Liposomes for Vulnerable Atherosclerotic Plaque Imaging

Abstract

From the in vitro uptake study, it has been demonstrated that macrophage targeting was accomplished by PS modification. Also, an atherosclerotic region was successfully detected by (111)In-PS200 in apoE-/- mice and Watanabe heritable hyperlipidemic rabbits in vivo. Liposome modification to obtain slower blood clearance and lower liver uptake would be required to improve the SPECT images.
