Targeting mannose receptor expression on macrophages in atherosclerotic plaques of apolipoprotein E-knockout mice using 68 Ga-NOTA-anti-MMR nanobody: non-invasive imaging of atherosclerotic plaques
2019
Background
Rupture-prone atherosclerotic plaques are characterized by heavy macrophage infiltration, and the presence of certain macrophage subsets might be a sign for plaque vulnerability. The mannose receptor (MR, CD206) is over-expressed in several types of alternatively activated macrophages. In this study, our objective was to evaluate the feasibility of a Gallium-68 (68Ga)-labelled anti-MR nanobody (68Ga-anti-MMR Nb) for the visualization of MR-positive (MR+) macrophages in atherosclerotic plaques of apolipoprotein E-knockout (ApoE-KO) mice.
