EBV-TCR-T Cells for EB Virus Infection After HSCT

EBV-TCR-T cells are prepared via lentiviral infection. patients with EBV emias or EBV positive PTLD will be enrolled, and donor derived EBV-TCR-T(HLA-A\*1101\\0201\\2402) cells will be intravenously infused with a escalated dose of 0.1-1×106 EBV-TCR-T cells. The EBV DNA copies and EBV-TCR-T cell proliferation will be monitored in the scheduled time (day 0, day 4, day 7, day 10, day 14, day 28).
