Orally administered marine (1→3)-β-d-glucan Phycarine stimulates both humoral and cellular immunity

(1 → 3)-β-d-Glucans represent highly conserved structural components of cell walls in yeast, fungi, or seaweed. However, it is still unknown how they mediate their effects. The aim of this study was to evaluate both intraperitoneal and oral application of seaweed-derived (1 → 3)-β-d-glucan Phycarine. Phycarine showed significant stimulation of phagocytosis by peripheral blood cells. In addition, the efficiency of chemotherapy of Lewis lung...
