免疫正电子发射断层扫描 (immuno-PET) 是一种无创成像方式,可以为感兴趣的细胞群的纵向评估提供动态方法。将单克隆抗体转化为基于单链可变片段(scFv)的 PET 成像剂将允许对各种可能的目标进行体内无创追踪。我们使用分选酶介导的酶标记与聚乙二醇化相结合,开发了一种基于抗小鼠 CD4 scFv 的 PET 成像剂,该成像剂由抗小鼠 CD4 单克隆抗体构建。这种抗CD4 scFv可以通过免疫PET监测CD4+ T细胞的体内分布。我们追踪了野生型小鼠、用 OT-II 和 OT-I T 细胞单克隆群重建的免疫缺陷受体以及 B16 黑色素瘤模型中的 CD4+ 和 CD8+ T 细胞。抗 CD4 和 -CD8 免疫 PET 显示,当接受者用弗氏完全佐剂中的卵清蛋白进行免疫时,转移到免疫缺陷小鼠体内的 CD4+ 和 CD8+ T 细胞的持久性得到改善。在荷瘤动物中,CD4+和CD8+T细胞的浸润随着肿瘤的生长而增加。这里描述的方法应该很容易适用于将临床有用的抗体转化为相应的 scFv PET 成像剂。
Immuno-positron emission tomography (immuno-PET), a noninvasive imaging modality, can provide a dynamic approach for longitudinal assessment of cell populations of interest. Transformation of monoclonal antibodies into single chain variable fragment-based (scFv) PET imaging agents would allow noninvasive tracking in vivo of a wide range of possible targets. We used sortase-mediated enzymatic labeling in combination with PEGylation to develop an anti-mouse CD4 scFv-based PET imaging agent, constructed from an anti-mouse CD4 monoclonal antibody. This anti-CD4 scFv can monitor the in vivo distribution of CD4+ T cells by immuno-PET. We tracked CD4+ and CD8+ T cells in wild type mice, in immunodeficient recipients reconstituted with monoclonal populations of OT-II and OT-I T cells, and in a B16 melanoma model. Anti-CD4 and -CD8 immuno-PET showed that the persistence of both CD4+ and CD8+ T cells transferred into immunodeficient mice improved when recipients were immunized with ovalbumin in complete Freund’s adjuvant. In tumor bearing animals, infiltration of both CD4+ and CD8+ T cells increased as the tumor grew. The approach described here should be readily applicable to convert clinically useful antibodies into the corresponding scFv PET imaging agents.
