Vgamma9Vdelta2 T cell proliferation agent, method for producing activated Vgamma9Vdelta2 T cells, and uses thereof

摘要

A Vgamma9Vdelta2 T cell proliferation agent includes at least a bisphosphonate, interleukin 2, and interleukin 18. Since has properties that improve cell viability by inhibiting cell death, IL-18 is presumably capable of acting as a cofactor for the bisphosphonate so as to significantly increase the effect of Vgamma9Vdelta2 T cell proliferation by the bisphosphonate and the IL-2. This allows providing a Vgamma9Vdelta2 T cell proliferation agent capable of growing Vgamma9Vdelta2 T cells with a proliferated efficiency significantly high compared to conventional methods so that the proliferated Vgamma9Vdelta2 T cells have a high antitumor activity and high cytokine productivity.
