To study possible variations of associated immune markers and cytokines involved in CIK cells killing against tumor cells, with MGC803 for assessment, we detected that IFN-γ and CD107a, as direct measurements of cytotoxicity of CIK cells, were induced by the co-incubation, whereas no significant change was observed on granzyme B secretion (Figure 6A). The gene discussed is IFNG; the disease is neoplasm.
