These results, together with the structural elucidation of the purified polysaccharides described above, indicate that the α-glucans in G. lucidum don't have any remarkable immunomdulating activities, but the effects of β-glucans on immune system depend on their glycosyl residue linkages and sugar chain conformation. Further, it is concluded that the 1, 3-linked backbone, relative lower side chain size and substitution, and a high-organized helical structure are the beneficial structural features for the immunostimulatory activity of β-D-glucans. However, the 1, 6-linked backbone may induce the immunosuppressive effect of β-D-glucans.

结合各纯化多糖的结构与构象分析的结果，可以得出以下结论：赤灵芝中的α-型葡取糖不具有显著的免疫调节作用，而β-型葡聚糖的免疫作用则与其糖链结构和糖链构象有密切关系，1，3-连接的主链，较低的分支取代率和较短的支链长度及高度有序的螺旋结构是β-型葡聚糖发挥免疫增强功能的有利结构因素，相反，1，6-连接的主链却可能引起多糖的免疫抑制作用。
