In Vivo Immunomodulatory Potential of Partial Purified Lectin from the Saffron Milk Cap Mushroom, Lactarius deliciosus (Agaricomycetes), against Colloidal Carbon Particles

Mushroom compounds and biomolecules are known for their biological beneficial effects and dietary properties. Their molecules can be used in immunology for their ability to stimulate immune cells and in biotherapy of diseases. In this study, the immunomodulatory effect using carbon clearance test in vivo of partial purified lectin of Lactarius deliciosus using DEAE-Sephacyl column, with sugar affinity against galactose, methyl-beta-D-galactopyranoside and lactose, showed a significant effect on phagocytic activity and half-life of carbon particles in mice with different concentrations (5, 10, 15, and 30 mg/kg). The results showed that the immunomodulatory effect increased in low doses and decreased in high doses compared with the control group p < 0.0001. L. deliciosus lectin exerted a dose-dependent immunostimulant activity toward the reticulo-endothelial system, and phagocytic activity toward macrophages and neutrophils in spleen and liver against the colloidal carbon.
