Abstract

Hericium erinaceus polysaccharide (HEP) is a Chinese herb and was reported to regulate the immune response effectively in different aspects. This study was aimed to investigate the influence of HEP on murine dendritic cells (DC). In this study, we found that HEP treatment induced DC maturation by the morphology and the up-regulation of co-stimulative molecules. The endocytosis activity was also reduced, which is also an important feature of maturation. HEP also increased the allogenic T cell proliferation in a MLR assay. Furthermore, it was found that HEP increase the expression level of IL-12. Finally, we concluded that HEP induced maturation of bone marrow DC.
