CD8A and neoplasm: Antigen-dependent tumor elimination is an essential prerequisite for adoptive T-cell therapy, therefore the cytolytic ability of receptor-transfected ZA-expanded γ/δ T cells, MACS-isolated γ/δ T cells, MACS-isolated CD8+ T cells, and PBMC stimulated with OKT3 was compared in a standard 4–6 h chromium release assay at indicated effector to target ratios (Fig. 5a and b, and Additional file 1: Table S5).
