Dectin-1:Immune Cell Receptor – Takano T, Motozono C, et al, “Dectin-1 Intracellular domain determines species-specific ligand spectrum by modulating receptor sensitivity,” JBC Papers in Press, Manuscrit M117.800847, Aug 28, 2017. Quote: “Dectin-1 is a well-characterized CLR [c-type lectin receptor] that recognizes B-glucan. …Our bodies are continuously exposed to and infected by various types of pathogens, most of which are recognized by pattern recognition receptors (PRRs)… An…additional member of emerging PRRs is the C-type lectin receptors (CLRs) [including Dectin-1] that sense pathogens or damaged tissues to trigger innate immune responses.”
Note: Dectin-1 has been shown to recognize species of several fungal genera, including Candida, Pnemocystis, Coccidioides, Penicillium and others. Recognition of these organisms triggers many protective pathways, such as fungal uptake by phagocytosis and killing via respiratory burst. Activation of dectin-1 also triggers expression of many protecting antifungal cytokines and chemokines.

Quote: “Fungal and particulate B-glucans…can be taken up by the M cells of Peyer’s patches, and interact with macrophages or dendritic cells and activate systemic immune responses to overcome the fungal infection. Dectin-1 receptor systems have been incorporated as the PRRs of B-glucans in the innate immune cells of higher animal systems, which function on the front line against fungal infection, and have been exploited in cancer treatments to enhance systemic immune function.“

Quote: “Dectin-1 is an innate immune pattern recognition receptor (PRR) that, through its ability to bind B-glucans, is involved in the recognition of several pathogenic fungi. Dectin-1 can stimulate a variety of cellular responses …including phagocytosis, cytokine production and the respiratory burst. ….Several advances in our understanding of Dectin-1 immunobiology have been made ….including demonstration of its ability to directly induce the development of adaptive immunity.”

Quote: “…In this study we show that despite its ability to bind both soluble and particulate B-glucan polymers, Dectin-1 signaling is only activated by particulate B-glucans. …The “phagocytic synapse” now provides a model mechanism by which innate immune receptors can distinguish direct microbial contact from detection of microbes at a distance, thereby initiating direct cellular anti-microbial responses only when they are required.“

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.

The recognition of fungal pathogens occurs through both opsonic (mainly complement) and nonopsonic mechanisms, and as conserved structural components, B-glucans…play an important role in the non-opsonic recognition of these [fungal] pathogens.
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.

American Journal of Clinical Nutrition, Vol. 70, No. 2, 208-212, August 1999. 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-cholesterolconcentrations 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.”

Quote: “B-glucans have been shown to support murine hematopoiesis suppressed by ionizing radiation or cytotoxic anti-cancer therapy. They also enhance stem cell homing and engraftment. Note: “Hematopoiesis” is the process of creating new blood cells in the body. All blood cells start off as hematopoietic stem cells, and then specialize or differentiate into myeloid cells including erythrocytes, megakaryocytes, monocytes, neutrophils, basophils, or eosinophils; or lymphoid cells including T-lymphocytes and B-lymphocytes.

Tumor Immunobiology Program and Stem Cell Biology Program, James Graham Brown Cancer Center, University of Louisville, Louisville, KY, USA. Sept 2005. Quote: “…Myelotoxic injury in the bone marrow (BM) as a consequence of total body irradiation (TBI) or granulocyte colony stimulating factor (G-CSF) mobilization results in the deposition of iC3b on BM [bone marrow] stroma [cell framework]. … Taken together, these observations suggest a novel role for C, CR3, and Beta glucan in the restoration of hematopoiesis following injury.” NOTE: Mice were treated for 12 days with beta glucan and exposed to a sublethal dose of radiation. 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.
