In this study, we found the increase of γδ T cells in the peripheral blood from pediatric living donor liver transplantation recipients. The feature of gd T cells from recipients is the oligoglonal expansion ; the TCR of γδ T cell showed Vd1 TCR and the variable region of Vδ1 chain showed mnoclonality. We succeeded the expansion of γδ T cell from PBMC of healthy volunteers in vitro, and those T cells showed the immunosuppressive activity. These immunosuppressive T cells will be applied to new immunosuppressive therapy by transfer of the cells.

本研究发现儿科活体肝移植受者外周血中γδ T细胞增多，受者gd T细胞的特点是寡球体扩张；γδ T细胞的TCR表现为Vd1 TCR和可变区。我们成功地从健康志愿者的PBMC中体外扩增出Vδ1链的γδT细胞，并且这些T细胞表现出免疫抑制活性。将通过细胞转移应用于新的免疫抑制疗法。
