Presentation of superantigen to T cells by CF and control B-cell linesa
| Presenting cells added to Jurkat T cells | IL-2, U/ml (mean ± SD)
|
|
|---|---|---|
| Without SEE | With SEE | |
| None | <1 | <1 |
| CF-2 | <1 | 15 ± 3 |
| CF-3 | <1 | 12 ± 0.3 |
| CF-4 | <1 | 13 ± 0.3 |
| CF-9 | <1 | 13 ± 0.2 |
| CF-11 | <1 | 11 ± 1 |
| Control 1 | <1 | 15 ± 1 |
| Control 2 | <1 | 13 ± 0.5 |
| Control 3 | <1 | 11 ± 1 |
a
B-cell lines (or none as a negative control) were added to the Jurkat T-cell line with and without SEE added. After 24 h, supernatant fluids were assayed for IL-2. B-cell lines alone without the T-cell line added did not make detectable IL-2 (<1 U/ml) (data not shown).
