In vitro, DSP was shown to enhance the viability(MTT assay) and phagocytosis of macrophages. In cyclophosphamide-induced immunosuppressed mice, DSP increased serum levels of TNF-α, IL-6 and IFN-γ(enzyme-linked immunosorbent assay, ELISA), and ameliorated the imbalance of the community of gut microbiota as detected by 16 S ribosomal RNA gene sequencing. These results suggest that DSP might be beneficial for patients under immunosuppressed conditions.展开更多

文摘To recognize the potential medicinal value of the Dendrobium sonia, polysaccharide(DSP) was extracted, purified, and investigated for its immunomodulatory activity.
