CD8+/ΔTCR T cells transduced with Epstein-Barr virus Latent Membrane Protein 2 ESEERPPTPY (EBV-LMP2ESE)–specific T-cell receptors (TCRs) lyse target cells presenting endogenous LMP2 peptide. A, Representative examples are shown of CD8+/ΔTCR T cells transduced with EBV-LMP2ESE–specific TCRs that were tested for their lytic capacity against malignant cells transduced with HLA-A*01:01 and LMP2 or against HLA-A*01:01–positive or –negative EBV-transformed lymphoblastoid cell lines (LCLs). CD8+/ΔTCR T cells transduced with a TCR targeting HLA-A*02:01/cytomegalovirus (CMV)–pp65NLV were used as control. B, Primary CD8+/ΔTCR T cells transduced with EBV-LMP2ESE–specific TCR-C1 were tested for their lytic capacity against 2 HLA-A*01:01–transduced subclones of the malignant Burkitt lymphoma cell line mutu-III. Mutu-III subclone c148 expressed LMP2 >100-fold higher compared to subclone c176. CD8+/ΔTCR T cells transduced with a TCR targeting HLA-A*02:01/CMV-pp65NLV were used as negative control. Data are shown from 1 experiment carried out in triplicate. Abbreviations: td; transduced, E:T, Effector:Target.
