Comparison of concentration of interferon (IFN)-γ and interleukin (IL)-4 in lymphocytes immunized by NIT-1, NIT-vector and NIT–hAAT cells (pg/mL,Mean±SD. n = 3).

*P<0·05, NIT-1, NIT-vector group versus Control group;
**P<0·01 NIT-hAAT versus Control, NIT-1 and NIT-vector group. No significant difference between the NIT-1 and NIT-vector groups was observed(P>0.05). No significant difference between the NIT-1primed lymphocytes or NIT-vector primed lymphocytes and the NIT–hAAT primed lymphocytes was observed(P>0.05).
