Abstract

Translocator protein (TSPO) is involved in several cellular mechanisms such as steroidogenesis, immunomodulation, cell proliferation and differentiation. Overexpressed in several neurodegenerative diseases and brain cancer, TSPO radioligands have been developed over the last 20 years in positron emission tomography (PET) imaging. Recently, TSPO radioligands have extended beyond their initial application due to their specific binding to activated macrophages, making them a compelling biomarker for deciphering the intricacies of the tumor microenvironment (TME). In this review, we synthesized recent progress from the evaluation of TSPO-specific PET tracers in various peripheral tumor models and highlighted the hurdles and limitations associated with heterogeneous uptake in healthy tissue and tumor regions to achieve the clinical development of such a radiotracer.

TSPO 放射配体的潜力:连接脑肿瘤诊断与周边地区。
转运蛋白(TSPO)参与多种细胞机制,如类固醇生成、免疫调节、细胞增殖和分化。TSPO 在多种神经退行性疾病和脑癌中过度表达,过去 20 年来,TSPO 放射性配体已被开发用于正电子发射断层扫描(PET)成像。最近,TSPO 放射性配体因其与活化巨噬细胞的特异性结合而超出了其最初的应用范围,成为了解读错综复杂的肿瘤微环境(TME)的一种引人注目的生物标记物。在这篇综述中,我们总结了在各种外周肿瘤模型中评估TSPO特异性PET示踪剂的最新进展,并强调了与健康组织和肿瘤区域异质性摄取相关的障碍和限制,以实现这种放射性示踪剂的临床开发。
