การใช้เป็นสารต้านจุลชีพ (Antimicrobial) และเสริมยาปฎิชีวนะ (Antibiotics)

Antibiotics: Tzianabos AO, Cisneros RL; “Prophylaxis with the immunomodulator PGG glucan enhances antibiotic efficacy in rats infected with antibiotic-resistant bacteria,” Ann NY Acad Sci 797: 285-287; Oct 1996.* Quote“Results of these studies demonstrated that prophylaxis with PGG glucan in combination with antibiotics provided enhanced protection against lethal challenge with Escherichia coli or Staphylococcus aureus as compared with the use of antibiotics alone.”

Antimicrobial Activity: Goodridge H, Reyes C, Becker C et al; “Activation of the innate immune receptor Dectin-1 upon formation of a ‘phagocytic synapse'” Nature, Vol 472 p 471-475, April 28, 2011. * Quote: “…Dectin-1 is a pattern-recognition receptor expressed by myeloid phagocytes (macrophages, dendritic cells and neutrophils) that detects b-glucans in fungal cell walls and triggers direct cellular antimicrobial activity… . Despite its ability to bind both soluble and particulate B-glucan polymers, Dectin-1 signaling is only activated by particulate B-glucans. …Studies in mice and humans have demonstrated an important role for Dectin-1 in anti-fungal defense. Dectin-1 signals activate anti-microbial phagocytosis, production of ROD [reactive oxygen species] and inflammatory innate immune responses, and influence the development of adaptive immunity…”

Antimicrobial Activity: 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: “…the B-glucans have been shown to activate macrophages to enhance their antimicrobial activity.  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.”
