We next tested the on-target killing potential of 10LH using available HLA-A*24:02 and HLA-A*23:01 neuroblastoma cell lines (SKNAS, NBSD and SKNFI) and demonstrated complete tumour cell killing and potent IFN-γ release after 24 h at 5:1 effector:target ratio (Fig. 4a–c, Supplementary Video 1). The gene discussed is HLA-A; the disease is neuroblastoma.
