To test how superior metabolic and cellular fitness of GLUT3-TCM cells translated to in vivo function, B16-OVA IDO+ tumor-bearing mice were preconditioned by myeloablative irradiation and then intravenously (I.V.)injected with gene-modified OT1 TCR T cells and monitored over time (Figure 5A). Here, SLC2A3 is linked to neoplasm.
