Cumulative effect of resveratrol (RVT) and curcumin (CMN) on proliferation and cytokine secretion by T cells. Equal concentrations (20 μM) of RVT and CMN were cultured separately or in combination with concanavalin A (ConA)-stimulated lymphocytes. The culture conditions for proliferation and lymphokines secretion were the same as stated in the legends to Figs 1 and 2. The data are the mean ± standard error (s.e.) of triplicate determinants for proliferation (a), interferon (IFN)-γ (b) and IL-4 (c) secretion. *P < 0·05 compared to cells cultured with ConA.
