Figure 4. DIZE attenuated neuroinflammation in the brain of SAMP8 mice. (A) The protein levels of IL-1α in the brain were investigated by ELISA. (B) The protein levels of IL-1β in the brain were investigated by ELISA. (C) The protein levels of IL-6 in the brain were investigated by ELISA. (D) The protein levels of TNF-α in the brain were investigated by ELISA. All data were analyzed by one-way ANOVA followed by Tukey’s post hoc test. Columns represent mean ± SD (n=8 per group). *P<0.05 versus age-matched vehicle-treated SAMR1 control mice. #P<0.05 versus vehicle-treated SAMP8 mice.
