TCA synergized the cytotoxicity of CIK cells to K562 cells. A) Effect of TCA on cytotoxic activity by CIK cells to K562 cells at the indicated effector:target ratio of 0:1. B) Effect of TCA on cytotoxic activity by CIK cells to K562 cells at the indicated effector: target ratio of 25:1. C) Effect of TCA on cytotoxic activity by CIK cells to K562 at the indicated effector: target ratio of 50:1. n=5. Mean±SD. bP<0.05 vs Control. eP<0.05 vs 120 μmol/L TCA treated continuously. TCA washout group: target cells were pretreated with TCA for 4 h and then washed out in the presence of CIK cells. TCA continuously treated group: target cells were pretreated with TCA for 4 h and then for another 5 h in the presence of CIK cells.
