제목 Optical Molecular Imaging of Atheroma Inflammation with a Novel, Mannose Receptor Targeting Near-infrared Fluorescence Probe in Genetically Engineered Mice and Atheromatous Rabbits
초록 A novel NIRF probe was fabricated by chemically conjugating glycol chitosan with mannose-PEG, cholesterol and NIRF dyes such as Cy5.5 for mouse imaging and Cy7 for rabbit imaging. In vitro, NIRF probe was selectively uptaken by RAW264.7 cells, and NIRF signals were estimated to be 10-fold over control group. Plaque macrophage NIRF signals were prominently enhanced in carotid artery of apoE -/- mice by multispectral laser confocal fluorescence imaging in vivo, and in coronary sized vessels of atheromatous rabbits by fluorescence reflectance imaging, which were induced by balloon induced endothelial denudation with a high-cholesterol diet for 12 weeks. Our newly developed mannose receptor targeting NIRF probe was able to selectively target and image macrophage-rich atheromata both in the mice artery and in coronary sized rabbit vessels.
