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.
