Title
Self-therapeutic HDL mimicking nanoparticles for detection of atherosclerotic plaques
Abstract
Plaque build up inside arteries due to excessive cholesterol deposition is the hallmark of atherosclerotic heart disease [1]. Early detection of vulnerable atherosclerotic plaques could prove to be highly useful for diagnosis and therapy of the disease. Magnetic resonance imaging (MRI) is one such techniques that can be employed for efficient detection of plaques [2]. With these objectives in mind, we have designed iron oxide loaded high density lipoprotein (HDL) mimicking nanoparticles [3] that not only enables MR imaging of atherosclerotic plaques but also are capable of removing cholesterol and triglyceride from the body. These nanoparticles were impregnated with suitable surface functionalities so that they can target macrophages selectively and thus can enhance MRI contrast. The technology described here uses biocompatible polymers and lipids for the construction of a HDL mimicking biodegradable nanoparticle and it could be a potent theranostic tool for coronary heart diseases.
