چکیده

Beta-glucans are a heterogeneous group of natural polysaccharides mostly investigated for their immunological effects. Due to the low systemic availability of oral preparations, it has been thought that only parenterally applied beta-glucans can modulate the immune system. However, several in vivo and in vitro investigations have revealed that orally applied beta-glucans also exert such effects. Various receptor interactions, explaining possible mode of actions, have been detected. The effects mainly depend on the source and structure of the beta-glucans. In the meantime, several human clinical trials with dietary insoluble yeast beta-glucans have been performed. The results confirm the previous findings of in vivo studies. The results of all studies taken together clearly indicate that oral intake of insoluble yeast beta-glucans is safe and has an immune strengthening effect.

Immune modulation by non-digestible and non-absorbable beta-1,3/1,6-glucan

Chemistry of beta-1,3/1,6-glucans Beta-glucans comprise a very diverse group of polysaccharides (even paper) in which glucose molecules as the only building block are linked together by beta-linkages. Only very few beta-glucan structures, notably beta-1,3/ 1,6-glucans, are bioactive in the sense that they interact with receptors on immune cells and elicit specific biological responses. Beta-1,3...

Covalent association of beta-1,3-glucan with beta-1,6-glucosylated mannoproteins in cell walls of Candida albicans.

Yeast and hyphal walls of Candida albicans were extracted with sodium dodecyl sulfate (SDS). Some of the extracted proteins reacted with a specific beta-1,6-glucan antiserum but not with a beta-1,3-glucan antiserum. They lost their beta-1,6-glucan epitope after treatment with ice-cold aqueous hydrofluoric acid, suggesting that beta-1,6-glucan was linked to the protein through a phosphodiester b...

PURPOSE The effect of brewers' yeast (1,3)-(1,6)-beta-D-glucan consumption on the number of common cold episodes in healthy subject was investigated. METHODS In a placebo-controlled, double-blind, randomized, multicentric clinical trial, 162 healthy participants with recurring infections received 900 mg of either placebo (n = 81) or an insoluble yeast (1,3)-(1,6)-beta-D-glucan preparation (n ...

Effect of Dietary β-1,3/1,6-glucan Supplementation on Growth Performance, Immune Response and Plasma Prostaglandin E2, Growth Hormone and Ghrelin in Weanling Piglets

The experiment was conducted to evaluate the effect of β-1,3/1,6-glucan on growth performance, immunity and endocrine responses of weanling piglets. One hundred and eighty weanling piglets (Landrace×Large White, 7.20±0.25 kg BW and 28±2 d of age) were randomly fed 1 of 5 treatment diets containing dietary β-1,3/1,6-glucan supplemented at 0, 25, 50, 100 and 200 mg/kg for 4 wks. Each treatment wa...

Direct enhancement of the phagocytic and bactericidal capability of abdominal macrophage of chicks by beta-1,3-1,6-glucan.

Salmonella enterica serovar Enteritidis is the major zoonotic and intracellular pathogen. Different strategies have been developed to prevent the S. Enteritidis infection. The beta-1,3-1,6-glucan of Schizophyllum commune was used as an immunological booster to determine the minimal dietary level of beta-glucan that would restrict S. Enteritidis infection through the effects of beta-glucan on th...
