For this purpose, cells of the immune system express receptors which recognize evolutionarily conserved structures expressed by various pathogens but absent from host cells. ...Dectin -1 is a type II transmembrane protein which binds beta-1,3 and beta-1,6 glucans. It [Dectin-1`] is expressed on most cells of the innate immune system and has been implicated in phagocytosis as well as killing of fungi by macrophages, neutrophils and dendritic cells."

April 2005, 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]

Indeed, many of the B-glucan receptors...have been shown to contribute to the recognition and phagocytosis of these organisms [fungal pathogens].  ... B-glucans, especially in particulate form, can produce proinflammatory and antimicrobial responses through the TLRs and Dectin-1 [cell receptors for B-glucan]. Many of these responses are required for the control of fungal infections, such as the production of TNF-Alpha, and is an essential early cytokine required for the control of infections with C. albicans, A. fumigatus, C. neoformans, and H capsulatum. This is also true for IL-12, another important anti-fungal cytokine... . Thus B-glucans appear to have an important role in the innate immune response to fungal pathogens and in initiating a protective adaptive response."

Quote: "...The aims of the present study were to examine the safety of pretreatment with beta-1,3/1,6-glucan in patients scheduled for coronary artery bypass grafting (CABG), and to investigate whether beta-1,3/1,6-glucan pretreatment could suppress inflammatory response and protect against ischemia-reperfusion injury following CABG.  ......Twenty one patients scheduled for CABG were assigned to oral beta-1,3/1,6-glucan 700 mg (Group 1) or 1 400 mg (Group 2) five consecutive days before surgery and were compared with a control group (Group 3). Blood samples were drawn preoperatively and on the first, third and fifth postoperative day for analysis of acute-phase reactants, hematology, cytokines and myocardial enzymes. CONCLUSIONS: Beta-1,3/1,6-glucan pretreatment is safe in patients undergoing CABG [Coronary artery bypass grafting] and may protect against ischemia reperfusion injury following CABG.

Quote: "The purpose of this study was to evaluate the effect on serum lipids of a yeast-derived ß-glucan fiber in 15 free-living, obese, hypercholesterolemic men. ... The yeast-derived ß-glucan fiber significantly lowered total cholesterol concentrations and was well tolerated…The link between elevated plasma LDL-cholesterol concentrations and the risk of developing coronary artery disease has been clearly established…Elevated plasma cholesterol and, in particular, LDL-cholesterol concentrations are associated with increased risk of coronary artery disease, whereas an elevated of HDL-cholesterol concentration is inversely correlated with the incidence of cardiovascular…The yeast-derived ß-glucan fiber lowered total cholesterol and raised HDL-cholesterol concentrations significantly. …

Unlike the significant increases in HDL-cholesterol concentrations observed 4 wk after the end of the study for subjects receiving the yeast-derived ß-glucan, none of the 24 studies of oat products reported significant changes in HDL concentration.Because higher HDL-cholesterol concentrations are associated with a reduced risk of developing coronary artery disease, there may be unique benefits of using the yeast-derived ß-glucan, and perhaps psyllium, rather than the oat products."

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.”

In addition to reducing intake of total fat, saturated fat and dietary cholesterol, serum cholesterol can be further reduced by added fiber, especially from sources rich in beta-glucan. ...The yeast-derived fiber is a more concentrated source of beta-glucan than the oat product."

The beta glucan treated animals had approximately 40 percent more cell formation units in the spleen than untreated mice. When beta glucan was given orally, survival of animals receiving a lethal dose of radiation after stem cell transplantation was significantly enhanced. Forty days following radiation exposure, approximately 30 percent of mice treated with beta glucan survived compared with only 3 percent of untreated animals.

Note on various Glucan forms: Beta 1,3/1,6-D glucan is a baker's yeast-derived beta glucan with a Beta 1,6 linkage (4-8%) and the molecule skewed to the right. MG Glucan is a specially processed proprietary form of microparticulate Beta 1,3/1,6 glucan that is uniform homogeneous and non-aggregated purified Beta 1,3-D glucan that does not reaggregate after the digestive process.  “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.  Beta 1,4 glucan is derived from oats and barley, minimally effective in immune potentiation and not included in this research summary of forms of Beta 1,3/1,6 glucan.  Many beta glucans are marketed under various trademark names that are not unique ingredient formulations.
