IFN-γ and IL-4 production of CD3/CD28 costimulated naive CD4+ T cells from rheumatoid arthritis patients (n = 9) stimulated for 5 days in the presence of IL-7. Because of exogenously added IL-4, only the production of IFN-γ is shown for cells cultured in the presence of IL-4 or of IL-7 and IL-4. *P < 0.05, statistically significant differences versus control cultures in the absence of added cytokines (con). A significant difference between IL-7 and IL-7/IL-4 is also indicated (**P < 0.01).
