Figure 6

Effects of CTD-1 on cytokine production by ConA-stimulated splenocytes. Splenocytes (4 × 105 cells/well) were incubated for 48 h with CTD-1 and ConA (2 μg/mL). Culture supernatants were collected and analyzed by using ELISA for levels of IL-2 (a), IFN-γ (b). Effect of CSA (1 μM) was set as positive group. Results are expressed as mean ± S.D. , compared with control.
