We developed a novel approach to bioluminescent T cell imaging (BLI) using a membrane-anchored form of the Gaussia luciferase (GLuc) enzyme, termed extGLuc, which we could stably express in both mouse and human primary T cells. In vitro, extGLuc+ cells emitted significantly higher bioluminescent signal when compared to cells expressing GLuc, Renilla luciferase (RLuc), and membrane-anchored RLuc (extRLuc). In vivo, mouse extGLuc+ T cells exhibited higher bioluminescent signal when compared to GLuc+ and RLuc+ T cells. Application of this imaging approach to human T cells genetically modified to express tumor-specific chimeric antigen receptors (CARs) enabled us to demonstrate in vivo CAR-mediated T cell accumulation in tumor, T cell persistence over time, and concomitant imaging of T cells and tumor cells modified to express firefly luciferase (FFLuc). This sensitive imaging technology has application to many in vivo cell based studies in a wide array of mouse models.
