IL 1 and TNF Alpha Production: Hunter KW, Jr. Berner MD, Sura ME Alvea BN, “IFN-gamma primes macrophages for enhanced TNF-alpha expression in response to stimulatory and non-stimulatory amounts of microparticulate beta-glucan.,” Immunol Lett ; 15:98(1): 115-22. Department of Microbiology and Immunology, University of Nevada School of Medicine, Applied Research Facility, MS-199, Reno, NV 89557, USA. 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]

IL 1 and TNF-µ Production :  Hunter K, Washburn R, “Efficacy of topical antimicrobial acid and immunostimulatory B-Glucan in Animal Models of Cutaneous Infection,” U Nevada Medical School-Applied Res Grant, Aug 1998.  Quote: “Our laboratory has developed preliminary evidence that B-1,3/1,6 glucans possesses immunostimulatory activity for macrophages in vitro, leading to secretion of the Th-1 cytokines IL-1 B, IL-12, and TNF-µ.”

IL-1 Enhancement: Poutsiaka D.D., et al, “Cross-linking of the beta-glucan receptor on human monocytes results in interleukin-1 receptor antagonist but not interleukin-1 production,” Blood 82: 3695-3700 ; Dept of Med, New England Med Ctr, Boston, MA. 1993. Quote: “Because of their differential effects on cytokine production, beta-glucans may be used to therapeutic advantage in the diseases in which IL-1 is implicated.”*

Immune response potentiation: Goodridge HS, Reyes CN, Becker CA, Katsumoto TR, Ma J, Wolf AJ, Bose N, Chan AS, Magee AS, Danielson ME, Weiss A, Vasilakos JP, Underhill DM; “Activation of the innate immune receptor Dectin-1 upon formation of a ‘phagocytic synapse’,” IBD and Immunobiolgy Research Institute, Available Oct 28, 2011. Quote: “The ‘phagocytic synapse [of particulate B-glucan]…provides a…mechanism…thereby initiating direct cellular antimicrobial responses only when they are required.”  Note: Particulate beta 1,3/1,6 glucan potentiates an immune response when a microbe is directly contacted, but does not stimulate an immune response indiscriminately.

Immune response potentiation: Brown G D, Gordon Siamon; “Fungal B-Glucans and Mammalian Immunity.” Sir William Dunn Sch of Pathology, U of Oxford, UK, Immunity, Vol19, 311-316, 2003.  Quote: B-Glucans are structural cell wall polymers of many fungi which possesses  immunomodulatory activities. …The innate immune response is essential for the control of fungal infections, and there is increasing evidence that B-glucans are involved in initiating many aspects of this response.  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.

…particulate B-glucans can directly activate leukocytes, stimulating their phagocytic, cytotoxic, and antimicrobial activities, including the production of reactive oxygen and nitrogen intermediates.  In addition, these carbohydrates [B-glucans] stimulate the production of proinflammatory mediators, cytokines and chemokines such as IL-8, IL1, IL-6 and TNF Alpha.  Stimulation by particulate B-glucans also enhances the ability of macrophages to recognize and clear  apoptotic [dying or dead] cells… .”  

Immune response potentiation: Jordan F, Hunter Jr. KW, Gault R, “Method for preparing small particle size glucan in a dry material,” U.S. Patent 6,476,003. November 2002. Quote: “The greater generation and/or production of NO (Nitric Oxide) demonstrates the enhanced activity of the macrophage with a small particle size glucan which is indicative of an activity level of an immune system. … The measurement of NO production is indicative of an oxidative burst that kills and/or destroys the ingested microbes and/or particles by the macrophage.

As a glucan re-aggregates into particles of greater than one micron in diameter, it appears to pass through an animal or human digestive system without substantially complete absorption.

… As the glucan re-aggregates to a size of greater than one micron in diameter, some of the beneficial effect of the glucan is not achieved because the macrophage receptors are not activated as readily by glucan greater than one micron in diameter because the receptor size on corresponding cells and molecules that accept the glucan is generally about one micron in size.

…The greater percentage phagocytosis demonstrates the enhanced activity of the macrophage and the small particle size glucan’s ability to activate the immune system.”

“Compared with the aggregated form of B-glucan, the B-glucan microparticles … are more effective at enhancing phagocytosis by peritoneal macrophages following oral administration. Although both aggregated [5-100-µ micron diameter] and microparticulate [1-2-µ micron diameter] glucans enhanced peritoneal macrophage activation when administered orally in mice, the microparticulate glucan was significantly better than the aggregated form.”

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]

Organ Injury – Sepsis: Sener G, Toklu H, et al; “Protective effect of beta-glucan against oxidative organ injury in a rat model of sepsis,” Int Immunopharmacol:1387-96 Epub 2005/Aug 2005. Quote: “Sepsis leads to various organ damage and dysfunction. One of the underlying mechanisms is thought to be oxidative damage due to generation of free radicals. …Elevated plasma TNF-alpha levels in septic rats [was] significantly reduced to control levels in beta-glucan treated rats. Since beta-glucan administration reversed these oxidant responses, it seems likely that beta-glucan protects against sepsis-induced oxidative organ injury.”

The efficacy of methotrexate is often limited by severe side effects and toxic sequelae [disease condition caused by a disease], where oxidative stress [free radical damage] is noticeable. … Thus, the findings of the present study suggest that beta-glucan, through its antioxidant and immunoregulatory effects, may be of therapeutic value in alleviating the leukocyte apoptosis [white immune cell death], oxidative [free radical] tissue injury and thereby the intestinal and hepatorenal [liver or kidney] side effects of methotrexate treatment.”

Similarly, serum ALT, AST levels, as well as LDH and TNF-alpha, were elevated in the acetaminophen-treated groupbeta-d-glucan treatment reversed all of these [liver toxicity] biochemical indices, as well as histopathological alterations that were induced by acetaminophen. In conclusion, these results suggest that beta-d-glucan exerts cytoprotective effects against oxidative injury through its antioxidant properties and may be of therapeutic use in preventing acetaminophen toxicity.”

Immunopharmacol; 6(2):156-69, Marmara U., Istanbul, Turkey; Epub Aug 2005/Feb 2006. Quote: “Thermal injury may lead to systemic inflammatory response, and multiple organ failure. The results indicate that both systemic and local administration of beta-glucan were effective against burn-induced oxidative tissue damage in the rat.  Beta-glucan, besides their immunomodulatory effects, have additional antioxidant properties.  Therefore, beta-glucans merit consideration as therapeutic agents in the treatment of burn injuries.”

Quote: “…there was evidence that macrophages, key target cells for the immunopharmacological activity of B-glucans, preferentially ingest particles in the 1-2-µ (micron) diameter size range.

Compared with the aggregated [5-100-µ micron diameter] form of B-glucan, the B-glucan microparticles remain in suspension longer for pharmaceutical applications and are more effective at enhancing phagocytosis by peritoneal macrophages following oral administration.

Although both aggregated and microparticulate glucans enhanced peritoneal macrophage activation when administered orally in mice, the microparticulate glucan was significantly better than the aggregated form”

Particle Size: Jordan F, Hunter Jr. KW, Gault R, “Method for preparing small particle size glucan in a dry material,” U.S. Patent 6,476,003. November 2002. Quote: “The greater generation and/or production of NO (Nitric Oxide) demonstrates the enhanced activity of the macrophage with a small particle size glucan which is indicative of an activity level of an immune system. … The measurement of NO production is indicative of an oxidative burst that kills and/or destroys the ingested microbes and/or particles by the macrophage. As a glucan re-aggregates into particles of greater than one micron in diameter, it appears to pass through an animal or human digestive system without substantially complete absorption.

… As the glucan re-aggregates to a size of greater than one micron in diameter, some of the beneficial effect of the glucan is not achieved because the macrophage receptors are not activated as readily by glucan greater than one micron in diameter because the receptor size on corresponding cells and molecules that accept the glucan is generally about one micron in size.

…The greater percentage phagocytosis demonstrates the enhanced activity of the macrophage and the small particle size glucan’s ability to activate the immune system.”
