The significant presence of intratumoral B7H3.CAR EBVSTs, along with increased expression of activation-induced PD-1 with TIM-3 (Supplementary Fig. S4B), provides evidence that B7H3.CAR EBVSTs migrated efficiently into tumor sites where they exerted potent antitumor activity. This evidence concerns the gene HAVCR2 and neoplasm.
