| Stimulation | Level of cytokine secretion (pg/ml)

||||
|---|---|---|---|---|---|
| IFN-γ | IL-2 | IL-4 | IL-10 | TNF-α | |
| Mock | 2,800 ± 932 | 1,887 ± 381 | 66 ± 17 | 263 ± 9 | 29 ± 0 |
| Sham | 4,399 ± 729 | 2,487 ± 450 | 109 ± 9 | 284 ± 10 | 34 ± 2 |
| gp120 | 172,144 ± 50,77 | 32,793 ± 6,459 | 515 ± 72 | 570 ± 81 | 34 ± 3 |
| gp120/GM | 183,127 ± 41,181 | 38,983 ± 2,396 | 503 ± 72 | 771 ± 21 | 37 ± 1 |
| gp120/MIP | 286,344 ± 62,971 | 45,862 ± 4,800 | 513 ± 43 | 610 ± 49 | 37 ± 3 |
| gp120/GM/MIP | 1,858,355 ± 500,472 | 199,279 ± 43,340 | 306 ± 66 | 813 ± 91 | 39 ± 1 |
aGroups of mice (n = 4 per group) were primed with a sham plasmid, the gp120 DNA vaccine alone, or cytokine-augmented DNA vaccines. These mice were then boosted at week 8 with DNA and at week 24 with 106 particles of rAd5. Levels of cytokine secretion (picograms per milliliter) by recombinant gp120-stimulated splenocytes were assessed by ELISA. Splenocytes from naïve mice (mock) were included as a control to determine baseline levels of cytokine secretion.
