The effect of taVNS on the expression of α7nAchR, IL-1β, NF-kB p65 and p-NF-kB p65 in the hippocampus. a Effect of taVNS on the expression of α7nAchR in hippocampus of rats. b Effect of taVNS on the expression of IL-1β in hippocampus of rats. c Effect of taVNS on the expression of NF-kB p65 in hippocampus of rats. d Effect of taVNS on the expression of p-NF-kB p65 in hippocampus of rats. The values are presented as mean ± SD. One-way ANOVA with Tukey post hoc test was performed for statistical analysis. *P < 0.05 vs. the control group, ***P < 0.001 vs. the control group; ##P < 0.01 vs. the model group, ###P < 0.001 vs. the model group; △P < 0.05 vs. the taVNS group, △△P < 0.01 vs. the taVNS group (n = 6 per group)
