Abstract
Polysaccharide is a major bioactive component of mushrooms. In this study, for the first time, starting from a new Lentinula edodes polysaccharide L2, we prepared a novel L2-calcium complex and the process was optimized. Scanning electron microscopy and Fourier Transform infrared spectrometry were used for characterization. The immunostimulating activities of L2 and L2-calcium complex were measured by enhancing the production of two cytokines TNF-α and IL-6 in RAW264.7 cells. While L2-calcium complex significantly stimulates the secretions of TNF-α and IL-6 compared with the control, complex with calcium ion decreased the secretion of them. These facts indicate that calcium ion can modulate immune stimulating activity of Lentinula edodes polysaccharide L2.

- The significance of Lentinula Edodes for Immune: Consuming Lentinula Edodes (Shiitake) Mushrooms Daily Improves Human Immunity: A Randomized Dietary Intervention in Healthy Young Adults. ( Mushrooms are widely cited for their medicinal qualities, yet very few human intervention studies have been done using contemporary guidelines... Regular L. edodes consumption resulted in improved immunity, as seen by improved cell proliferation and activation and increased sIgA production. The changes observed in cytokine and serum CRP levels suggest that these improvements occurred under conditions that were less inflammatory than those that existed before consumption. )

( The role of glucan in stimulation of immune reactions has been studied for several decades... Short-term oral application of natural immunomodulating glucans from Maitake and Shiitake mushrooms strongly stimulated both the cellular and humoral branch of immune reactions. These activities were significantly higher than those of AHCC. )
