“Polysaccharopeptide”

Reversal of Inhibition of Reactive Oxygen Species Macrophages

These results suggest that the immunological functions of macrophages is related to the activity of glutathione peroxidase. The non-specific immunopolysaccharide might protect macrophages by the damage induced by reactive oxygen species by enhancing anti-oxidative capacity.[…]

Polysaccharopeptides derived from Coriolus versicolor potentiate the S-phase specific cytotoxicity of Camptothecin (CPT) on human leukemia HL-60 cells.

The present study shows that PSP increases the sensitization of the HL-60 cells to undergo effective apoptotic cell death induced by CPT. The pattern of sensitivity of cancer cells is similar to that of HL-60 cells. PSP rapidly arrests and/or kills cells in S-phase and did not interfere with the anticancer action of CPT. PSP is a potential adjuvant to treat human leukemia as rapidly proliferating tumors is characterized by a high proportion of S-phase cells.[…]
