ABSTRACT
In the present study, the immuno-enhancing effect of Eucommia ulmoides leaf polysaccharide (ELP) was investigated in immunosuppressed mice induced by cyclophosphamide (CTX). To evaluate the immune enhancement mechanism of ELP, the immunoregulation effect of ELP was evaluated in vitro and in vivo. ELP is primarily composed of arabinose (26.61%), galacturonic acid (25.1%), galactose (19.35%), rhamnose (16.13%), and a small amount of glucose (12.9%). At 1000~5000 µg·mL-1, ELP could significantly enhance the proliferation and the phagocytosis of macrophages in vitro. Additionally, ELP could protect immune organs, reduce pathological damage, and reverse the decrease in the hematological indices. Moreover, ELP significantly increased the phagocytic index, enhanced the ear swelling response, augmented the production of inflammatory cytokines, and markedly up-regulated the expression of IL-1ß, IL-6, and TNF-α mRNA levels. Furthermore, ELP improved phosphorylated p38, ERK1/2, and JNK levels, suggesting that MAPKs might be involved in immunomodulatory effects. The results provide a theoretical foundation for exploring the immune modulation function of ELP as a functional food.
