| Abstract: | We developed a new approach to bioluminescent T cell imaging 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<sup>+</sup> cells emitted significantly higher bioluminescent signal when compared to cells expressing GLuc, Renilla luciferase (RLuc) or membrane-anchored RLuc (extRLuc). In vivo, mouse extGLuc<sup>+</sup> T cells showed higher bioluminescent signal when compared to GLuc<sup>+</sup> and RLuc<sup>+</sup> T cells. Application of this imaging approach to human T cells genetically modified to express tumor-specific chimeric antigen receptors (CARs) enabled us to show 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. This sensitive imaging technology has application to many in vivo cell-based studies in a wide array of mouse models. © 2009 Nature America, Inc. All rights reserved. |
