Scand J Immunol.Scand J Immunol Jul;78(1):61-8. doi: /sji Enhancement of intestinal immune function in mice by β-D-glucan from aureobasidium pullulans ADK-34. Tanioka A Tanioka A 1, Tanabe K, Hosono A, Kawakami H, Kaminogawa S, Tsubaki K,Tanabe KHosono AKawakami HKaminogawa STsubaki K Hachimura SHachimura S. Abstract β-Glucans, glucose polymers that are the main constituents of the outer cell walls of micro-organisms such as fungi and yeast, are known to play an immunostimulatory role. We prepared β-glucan (β-(1-3),(1-6)-D-glucan) from an edible cultured fungus through fermentation techniques using a strain of Aureobasidium pullulans ADK-34. The purity of this β-glucan preparation (AP-FBG) was demonstrated to be high through various instrumental analyses. We then examined the effects of AP-FBG on intestinal immune systems. … Therefore, AP-FBG may be a useful ingredient for preparing functional foods with immunomodulatory activities. [PMID:

Abstract J Immunol.J Immunol Feb 1;192(3): doi: /jimmunol Epub 2014 Jan 3. The (1->6)-β-glucan moiety represents a cross-reactive epitope of infection-induced malignancy surveillance. Dong H Dong H 1, Dai H, Hu X, Xiong SD, Gao XM.Dai HHu XXiong SDGao XM Abstract Exposure to pathogen-associated molecular patterns (PAMPs) by vaccination or infection is known to have beneficial effects on neoplastic diseases, although the underlying molecular mechanisms are so far unclear. In this article, we report that Abs against (1→6)-β-d-glucan, a typical microbial PAMP and a major target for high titer circulating natural Abs in healthy human subjects, cross-recognize a novel tumor-associated carbohydrate Ag on cancer cells. The (1→6)-β-glucan cross-reactive moiety is immunologically dominant in tumor cells, … Importantly, (1→6)-β-glucan-specific Abs significantly prolonged the survival and reduced the tumor size in mice inoculated with EL-4 tumors.

Int Immunopharmacol.Int Immunopharmacol Sep;9(10): doi: /j.intimp Epub 2009 Jun 30. Maitake beta-glucan enhances granulopoiesis and mobilization of granulocytes by increasing G-CSF production and modulating CXCR4/SDF-1 expression. Ito K Ito K 1, Masuda Y, Yamasaki Y, Yokota Y, Nanba H.Masuda YYamasaki YYokota YNanba H Abstract Previous studies have presented that Maitake beta-glucan (MD-Fraction) extracted from the fruit body of Grifola frondosa has an anti-tumor effect by activating the immune system. Recently, the stimulating effects of beta- glucans on hematopoiesis were identified as new characteristics of polysaccharides, possibly helping to relieve the immunosuppression which results from chemotherapies. We demonstrated that the production of granulocyte colony-stimulating factor (G-CSF) was significantly enhanced by MD-Fraction (8mg/kg, i.p.) in granulocytopenic model induced in mice using cyclophosphamide (200mg/kg, i.p.). … This finding presents opportunities to develop new therapeutic strategies against the immunosuppression caused by chemotherapies in cancer patients.
