Abstract

This study aims to evaluate the anti-cancer effect of gamma delta T (γδT) cells in an immunodeficient mouse model bearing human lung cancer (H460 lineage). Gamma delta T (γδT) cells were activated and proliferated in vitro until a concentration of at least 107 cells/ml was reached. Immune-deficient mice bearing human lung cancer were divided into 4 groups with 6 animals per group, including 1 control group and 3 treatment groups (GDT1, GDT2, GDT3). The three treatment groups were injected with 106 cells/10g, 5x106 cells/10g, and 107 cells/10g concentrations of γδT cells. After injection, at day 20, the GDT3 group with H460 human lung cancer had a smaller tumor volume, longer survival time, and lower death rate compared to the control group. The results suggest that γδT cells may be effective against human lung cancer in an immune-deficient mouse model of xenograft tumors.
