摘要

腹主动脉瘤（AAA）是一种退行性血管疾病，破裂后死亡率很高。目前还没有预测破裂的诊断方法，也没有有效的医学治疗方法来防止破裂。本研究表明，C-C趋化因子受体2型（CCR2）是AAA的治疗性生物标志物。在大鼠AAA模型中，我们确定了CCR2靶向正电子发射断层扫描放射性示踪剂[64Cu]Cu-DOTA-ECL1i预测AAA破裂的潜力。使用CCR2抑制剂，我们观察到有效预防AAA大鼠模型破裂。在人类中，CCR2正电子发射断层扫描显示患者沿AAA壁有强烈的放射性示踪剂摄取，而在健康志愿者中观察到的信号很少。

Chemokine Receptor 2 Is a Theranostic Biomarker for Abdominal Aortic Aneurysms

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.
