The number of NK cells that migrated toward U87MG GBM cells was significantly reduced in the TNFSF4-blocked T cell group (26.9% ± 2.0%, p = 0.027), and tended to decrease in the TNFRSF18-blocked T cell group (42.1% ± 9.6%, p = 0.195) and the IL12RB-blocked T cell group (37.8% ± 9.6%, p = 0.146) compared with the control T cells in which the expression of these three genes was not blocked (63.8% ± 5.9%) (Fig. 6B). The gene discussed is TNFSF4; the disease is glioblastoma.
