In Figure 4A (panel 3) of this article, the panel labeled “Tumor +Curcumin” was inadvertently placed in the “Curcumin” panel instead of the original “Curcumin” panel. The corrected version of Figure 4 is shown below as the revised Figure 4. The figure legend remains the same.

This error occurred during the revision process and does not affect the results, interpretations, or conclusions of the study. We apologize for this oversight.

The original article has been corrected.

Curcumin attenuates tumor-induced inhibition of T-cell proliferation. A Flow cytometric histogram display of CFSE fluorescence (x axis) versus counts (y axis) and B respective graphical representation used to determine proliferation of effector T cells isolated from untreated or curcumin-treated normal and tumor-bearing mice following stimulation with CD3 and CD28 antibodies. Values are mean ±SEM of five independent experiments. *P < 0.001 when compared with respective untreated/normal controls. CFSE, 5-(and-6)-carboxyfluorescein succinimidyl ester
