Resveratrol treatment alters the level of cytokines in the tumor-bearing mice. Cytokine levels of TNF-α, IFN-γ, TGF-β1 and IL-10 in blood (a) or tumors (b) of tumor-bearing mice at the end of treatment (day 21) were measured by ELISA. Some mice received 1 × 10⁶ CD8⁺CD122⁺ Tregs on day 3. Data are shown as mean ± SD (ns, nonsignificant; ND, not detectable; n = 4 mice/group; two-tailed t-test: *p < 0.05 and **p < 0.01). One of three separate experiments is shown
