β-1,3-Glucan  (Synonyms: β Glucan)

β-1,3-Glucan (β Glucan) is an orally active polysaccharide composed of glucose polymers. β-1,3-Glucan increase the activity of IKKβ kinase, enhances the production of nitric oxide. β-1,3-Glucan improves resistance to Vibrio harveyi infection. β-1,3-Glucan enhances immune response, promotes blood pressure recovery, reduces lung, kidney and liver damage, inhibits the growth of syngeneic tumors^{[1][2][3][4][5][6][7][8]}.

β-1,3-Glucan (PGG-Glucan; 0.1-3 μg/mL; 3 h) can enhance the oxidative burst response of leukocytes to soluble and particulate activators and their microbicidal activity in a dose-dependent manner^[1].
β-1,3-Glucan (0.5-5 mg/mL; 3 days) can significantly promote proliferation of L-929 fibroblasts^[3].
β-1,3-Glucan can increase the activity of IKKβ kinase in the murine monocytic cell line J774a.1, and also enhance the production of nitric oxide and superoxide in murine peritoneal macrophages^[8].

β-1,3-Glucan (0.09%; added to the diet; p.o.; twice a day; 8 weeks) promotes the growth of large yellow croaker, enhances innate immunity and improves the resistance to Vibrio harveyi infection^[2].
β-1,3-Glucan (40-160 mg/kg; p.o.; 5-10 days) enhances the proliferative response of spleen cells to mitogens, enhances the activity of natural killer cells and the lysosomal enzyme activity of peritoneal macrophages, and also inhibits the growth of syngeneic tumors in mice^[4].
β-1,3-Glucan (20 mg/kg/day, p.o.; 2 mg/kg/day, s.c.; oral administration for 14 days, subcutaneous injection for 3 days) can promote the recovery of blood pressure, reduce kidney and liver injuries, and also regulate cytokine levels in a rat model of endotoxemia^[5].
β-1,3-Glucan (2 mg/kg; i.m.; injected immediately after surgery and at 4 h after surgery) can improve the survival rate, reduce acute lung injury, inhibit the release of pro-inflammatory cytokines in a rat model of sepsis induced by cecal ligation and puncture (CLP)^[6].
β-1,3-Glucan (250-1000 mg/kg; p.o.; once a day; 18 days) prevents myelosuppression and splenomegaly caused by tumors in tumor-bearing mice^[7].
β-1,3-Glucan (150 mg/kg; p.o.; once daily; 7 days) can reverse the immunosuppression mediated by Aflatoxin B₁ (HY-N6615), increase the percentages of lymphocyte subsets and the levels of multiple cytokines in the male adult Balb/c mouse model^[8].
