“Turkey Tail mushroom”

CIMER – Coriolus versicolor (mushroom) – MD Anderson Cancer Center Page 1

The anti-cancer and immune stimulating properties of Coriolus versicolor have been attributed to two extracts from its cultured mycelium (thread-like extensions). These extracts are both protein-bound polysaccharides known as polysaccharide K (PSK) and polysaccharide-peptide (PSP). Hot water is required to extract these active components. {…}

Macrophage-stimulating activity of polysaccharides extracted from fruiting bodies of Coriolus versicolor (Turkey Tail Mushroom).

The macrophage-stimulating effect of Turkey Tail mushroom extracted from Coriolus versicolor (Turkey Tail mushroom) was investigated, and their effectiveness was compared with that of lipopolysaccharide (LPS). The purified polysaccharide (CV-S2-Fr.I) of C. versicolor obtained by Sepharose CL-6B gel chromatography stimulated macrophage lysosomal enzyme activity by 250% at a concentration of 100 microg/mL, which was higher than that of LPS at the same concentration. When CV-S2-Fr.I was used in combination with interferon-gamma, there was a marked cooperative induction of nitric oxide production. However, CV-S2-Fr.I had no effect on nitric oxide production by itself. The proportion of C3-positive macrophages in the CV-S2-Fr.I group increased by 7.2-fold compared with the control group.[…]
