(a) T cell proliferation and (b) the cancer cell cytotoxicity analyses of Ex3, scFvΔK-MMP-Ex3, and scFvΔK-MMP-Ex3 treated with the collagenase. (b) T-LAK cells were added to TFK-1 cells at a ratio of 0.5:1 (n = 4). Data are expressed as mean ± SD. The significance of the results was analyzed using one-way ANOVA and followed by Bonferroni’s post hoc test (*p < 0.05; Ex3 vs. scFvΔK-MMP-Ex3 + collagenase)
