细胞凋亡显像的研究现状及发展前景

对不同放射性核素、不同螯合剂和配体合成凋亡显像剂annexinV的标记、合成、各自的生物学特性作了全面的评价,并对实验结果和临床应用作了总结和分析,体外试验及体内显像表明,放射性核素标记annexinV及其衍生物能较灵敏地探测凋亡事件,细胞凋亡在心肌梗死、动脉粥样硬化及肿瘤形成等病理过程中发挥重要作用。凋亡显像能较好地评价心肌缺血再灌注损伤诱发的心肌凋亡,可早期评价和预测肿瘤放疗、化疗疗效,有助于指导建立个体化治疗方案。同时,对磁共振、超声、近红外线显像探测细胞凋亡作了分析,比较了不同影像学检查在探测细胞凋亡的优势和不足。

Apoptosis imaging: current state of the art and future perspective

This review provides a critical and thorough overview of the radionpharmaceutical development and in vivo evaluation of all apoptosis-detecting radioligands that emerged so far, along with these possible applications in nuclear medcine. Radiolabelled annexin bears the promise of becoming a clinically applied radio-pharmaceutical with potential applications in cardiology and oncology. Visualization of cell death is important in pathologies such as myocardial infarction, atherosclerosis, and cancer. Furthermore, radiolabelled annexin may be developed as a tool for monitoring cell death-induceing or cell death-preventing therapies. Some futue perspective are presented with the aim of promoting the development of potential new strategies in pursuit of the idealcell death-detecting radioligand.
