Astaxanthin enhanced the activities of antioxidant enzymes in LPS-induced DCs and LPS-challenged mice. (A–C) DCs were incubated with the indicated concentrations of astaxanthin and LPS (100 ng/mL) for 24 h. (D–F) C57BL/6 mice were orally given astaxanthin before LPS injection. Serum was sampled at 4 h after LPS injection. The levels of GPx, CAT, and SOD in the lysate of DCs or serum were measured as described in the Materials and Methods section. Results are from one representative experiment of three performed. Data are presented as means ± SD. The comparisons were performed with analysis of variance (ANOVA) (multiple groups). Different lowercase letters indicate significant differences between groups (p < 0.05).
