| IL-4 | 0.38 ± 0.28 | 2.65 ± 0.69 | 2.31 ± 1.86 | 3.85 ± 1.7 |
| IL-5 | 0.9 ± 0.48 | 2.48 ± 1.08 | 0.75 ± 0.19 | 3.54 ± 1.06 |

Splenocytes isolated from mice of the indicated genotypes were stimulated in vitro with 1 μg/ml CD3 and 1 μg/ml CD28 antibodies for 5 h and assessed for cytokine production by intracellular staining. Values shown represent the mean and standard deviation of the percentage of CD4+Foxp3− cells producing the corresponding cytokines (n = 4–7).
