Group	Cytokine production (pg/ml)b
	IFN-γ	IL-4	IL-10
PBS	48.03 ± 1.86	37.31 ± 1.76	40.97 ± 1.03
pEGFP	44.32 ± 4.43	36.58 ± 2.42	41.60 ± 2.01

^aSplenocytes from 3 mice per group on the 4th week after the final immunization.

^bValues for IFN-γ are for 96 h. Values for IL-10 are for 72 h. Values for IL-4 are for 24 h.

*Compared with PBS-adjuvant or pEGFP controls, P < 0.05.
