Moreover, the cytotoxic effects of γδ T cells on leukemia cell lines (Molt4, HL-60, and K562) and lymphoma cell lines (Raji and Daudi) were not influenced by G-CSF, TGF-β, and G-CSF + TGF-β induction compared with the control group (P = 0.116, P = 0.538, P = 0.617, P = 0.355, and P = 0.288, respectively) (Fig. 7). This evidence concerns the gene TGFB1 and lymphoma.
