Abstract
Abdominal aortic aneurysm (AAA) is a degenerative vascular disease with a high mortality upon rupture. There is no diagnosis to predict the rupture nor effective medical therapies to prevent rupture. Here we demonstrate that the C-C chemokine receptor type 2 (CCR2) is a theranostic biomarker for AAA. In rat AAA models, we determined the potential of a CCR2-targeted positron emission tomography radiotracer [64Cu]Cu-DOTA-ECL1i predicting AAA rupture. Using a CCR2 inhibitor, we observed the effective prevention of rupture in AAA rat models. In humans, CCR2 positron emission tomography showed intense radiotracer uptake along the AAA wall in patients while little signal was observed in healthy volunteers.
期刊介绍:
JACC: Basic to Translational Science is an open access journal that is part of the renowned Journal of the American College of Cardiology (JACC). It focuses on advancing the field of Translational Cardiovascular Medicine and aims to accelerate the translation of new scientific discoveries into therapies that improve outcomes for patients with or at risk for Cardiovascular Disease. The journal covers thematic areas such as pre-clinical research, clinical trials, personalized medicine, novel drugs, devices, and biologics, proteomics, genomics, and metabolomics, as well as early phase clinical trial methodology.
