Expression of perforin, granzyme B, and Fas ligand of activated T-cell subpopulation. There are greater percentage of perforin/granzyme B and FasL-expressing T cells after co-culturing tumors, T cells, and diabody when compared with the control. Nalm-6 cells preincubated with Ara-C stimulated more perforin (A)/granzyme B (B) and FasL (C) expressed by T cells than Nalm-6 cells alone. However, anti-CD3scFv or anti-CD19scF alone, combination of anti-CD3scFv and anti-CD19scFv, and anti-CD3/anti-Pgp have no effect. *p<0.05 and **p<0.01 were compared with controls. T and T+diabody groups are controls.
