Effects of <i>Acanthopanax senticosus</i> supplementation on innate immunity and changes of related immune factors in healthy mice

Abstract

(AS) can regulate the innate immunity of healthy animals, thus affecting the health of animals. However, there are few systematic reports on the changes of innate immune indices of healthy animals after consuming AS. The purpose of this project was to study the effect on healthy mice's innate immunity and changes of related immune factors induced by feeding AS root powder supplementation. The results showed that the killing rate of natural cells increased in a dose-dependent manner in a certain time period. Compared to the control group, the treatment groups (T1, T2 and T3) improved significantly in the innate immune index (lysozyme, β-defensin-2 and duodenal secretory IgA (SIgA) to varying degrees) and induced corresponding changes of immune factors at certain time periods. The correlation between SIgA and IFN-γ in mouse serum was enhanced, and the higher the concentration of AS in the diet, the stronger the correlation was. However, there was no significant difference in growth performance among groups. It is proved that AS supplementation can enhance innate immunity and change several relevant immune factors and cells of healthy mice without affecting growth performance.
