Involvement of phosphorylated compounds in stimulation of 1,4-β glucan synthases ofSaprolegnia monoica [PDF]

FEMS Microbiology Letters, 1991
The stimulation by ATP of β glucan synthase activities of cell-free extracts of Saprolegnia monoica was enhanced by the presence of glucose-phosphates. These effects were obtained in conditions of 1,4-β glucan synthesis; on the contrary, strong inhibition was observed during 1,3-β glucan production.

FT-IR Method Limitations for β-Glucan Analysis

Molecules, 2022
β-glucans are known as biological response modifiers. However, different sources can result in structural differences and as a result differences in their biological activity.

Cyclic diguanylic acid stimulates 1,4-μ-glucan synthase fromSaprolegnia monoica [PDF]

FEMS Microbiology Letters, 1991
Abstract 1,4-μ-Glucan synthase activity, but not 1,3-μ-glucan-synthase activity, from Saprolegnia monoica was stimulated by cyclic-diguanylic acid, an immediate activator of Acetobacter xylinum - cellulose synthase. This activator, which increased the V max without modifying the K m for UDP-glucose, was active on solubilized and partially ...

Spent Brewer’s Yeast as a Source of Insoluble β-Glucans

International Journal of Molecular Sciences, 2021
In the brewing process, the consumption of resources and the amount of waste generated are high and due to a lot of organic compounds in waste-water, the capacity of natural regeneration of the environment is exceeded.

β-Glucans from Yeast—Immunomodulators from Novel Waste Resources

Applied Sciences, 2022
β-glucans are a large class of complex polysaccharides with bioactive properties, including immune modulation. Natural sources of these compounds include yeast, oats, barley, mushrooms, and algae.

Immunotoxicity of soluble β-glucans induced by indomethacin treatment [PDF]

FEMS Immunology & Medical Microbiology, 1998
(1 --> 3)-Beta-D-Glucan (beta-glucan) is a biological response modifier that regulates host immune response. However, the side effects of this drug have not been extensively examined. In this study, we found that the combination of a beta-glucan and a nonsteroidal anti-inflammatory drug, indomethacin, induced lethal toxicity in mice. Lethal toxicity of

Detection of peptidoglycan and β-glucan with silkworm larvae plasma test [PDF]

FEMS Immunology & Medical Microbiology, 1996
A method to detect peptidoglycan and (1-->3) beta-D-glucan with silkworm larvae plasma (SLP) derived from the hemolymph of the silkworm, Bombyx mori was developed. SLP contains all of the factors of the pro-phenol oxidase cascade, an important self-defense mechanism of insects.

Role of anti-β-glucan antibody in host defense against fungi [PDF]

FEMS Immunology & Medical Microbiology, 2005
We have recently detected an anti-beta-glucan antibody in normal human and normal mouse sera. The anti-beta-glucan antibody showed reactivity to pathogenic fungal Aspergillus and Candida cell wall glucan. Anti-beta-glucan antibody could bind whole Candida cells. It also enhanced the candidacidal activity of macrophages in vitro.

Continuous Exposure to Non-Soluble β-Glucans Induces Trained Immunity in M-CSF-Differentiated Macrophages

Frontiers in Immunology, 2021
Beta-glucans enable functional reprogramming of innate immune cells, a process defined as “trained immunity”, which results in enhanced host responsiveness against primary (training) and/or secondary infections (resilience).

Isolation and characterization of periplasmic cyclic β-glucans ofAzorhizobium caulinodans [PDF]

FEMS Microbiology Letters, 2003
Oligoglucose molecules isolated from Azorhizobium caulinodans were characterized by compositional analysis, Smith degradation, matrix-assisted laser desorption/ionization time of flight mass spectrometry, and (1)H and (13)C nuclear magnetic resonance analysis. A.
