Quote: …"we have tested a new microparticulate form of beta-(1--> 3)-D-glucan (MG) from Saccharomyces cerevisiae for its ability to induce proinflammatory cytokine secretion in mouse peritoneal macrophages in vitro, and we have examined the effect of IFN-gamma. MG was rapidly phagocytized by peritoneal macrophages, and these MG-treated macrophages upregulated TNF-alpha, IL-6, and IL-1beta mRNAs and secreted these proinflammatory cytokines. These data suggest that a synergy between IFN-gamma and beta-glucan may have evolved to lower the threshold of sensitivity of the innate immune response to fungal pathogens.” [respond faster in attacking fungal pathogens – mycotoxins]

Heart Disease: Carrow, D.J.; “Beta-1,3-glucan as a Primary Immune Activator,” Townsend Letter; June 1996. Quote: “…immunosuppression is observed in people with stress-related disease such as coronary heart disease. Under such influences the number of macrophages [white immune cells] available are reduced and unable to participate in the immune cascade, which caused an even greater immunosuppression.
Beta 1,3 glucan has proven to both stimulate and activate the macrophage cells, which will counter these negative effects. …People with high risk of atherosclerosis should definitely add beta 1,3 glucan to their diet in addition to any cholesterol-reducing drugs.
Macrophage activation helps draw extra cholesterol from the blood, prevent further plaque formation on the arterial walls and phagocytes [eats] existing plaque which is recognized as a foreign body.”

Note on various Glucan forms: MG Glucan is a proprietary form of Beta 1,3/1,6 glucan processed to prevent reaggregation of the microparticulate insoluble particles which according to Medical School Research, enhances significantly the immune potentiation properties relative to globular or reaggregated glucans. Purified Beta 1,3-D glucan is a beta glucan with a Beta 1,6 linkage and the molecule skewed to the right. “PGG-glucan” is poly-[1,6]-B-D-glucopyranosyl-[1-3]-B-D-glucopyranose (b-1,6/1,3-glucan). “Beta glucans” refers generally, but not always, to Beta- 1,3/1,6-glucan. “Scleroglucan” and “PSAT” are two Beta-1,3/1,6-polysaccharides. Beta glucans are derived primarily from yeast cell wall, various fungi, grains, and mushrooms.
