Congo red inhibits in vitro β-glucan synthases of Saprolegnia [PDF]

FEMS Microbiology Letters, 1990
1,3-β- and 1,4-β-glucan synthases from Saprolegnia were inhibited in vitro by Congo red. This dye was found to be a non competitive inhibitor which prevented initiation and elongation of polymer chains.

β-Glucan Induces Training Immunity to Promote Antiviral Activity by Activating TBK1

Viruses, 2023
Many studies have shown that β-glucan induces a trained immune phenotype in innate immune cells to defend against bacterial and fungal infections. The specific mechanism involves cellular metabolism and epigenetic reprogramming.

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.

Characterization of cereal β-glucan extracts from oat and barley and quantification of proteinaceous matter. [PDF]

PLoS ONE, 2017
An extraction method for mixed-linkage β-glucan from oat and barley was developed in order to minimize the effect of extraction on the β-glucan structure.

Glucan and glycogen exist as a covalently linked macromolecular complex in the cell wall of Candida albicans and other Candida species

The Cell Surface, 2021
The fungal cell wall serves as the interface between the organism and its environment. Complex carbohydrates are a major component of the Candida albicans cell wall, i.e., glucan, mannan and chitin.

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.

β-Glucan, extracted from oat, enhances disease resistance against bacterial and parasitic infections [PDF]

FEMS Immunology & Medical Microbiology, 2003
The effect of beta-glucan, extracted from oats, on the enhancement of resistance to infections caused by Staphylococcus aureus and Eimeria vermiformis was studied in mice. In vitro study using macrophages isolated from the peritoneal cavity showed that beta-glucan treatment significantly enhanced phagocytic activity.

Protective effect of β-glucan against systemicStreptococcus pneumoniaeinfection in mice [PDF]

FEMS Immunology & Medical Microbiology, 2000
The antimicrobial effect of soluble beta-1,3-D-glucan from Sclerotinia sclerotiorum (SSG) was examined in mice experimentally infected intraperitoneally (i.p.) with Streptococcus pneumoniae serotypes 4 and 6B. SSG was administered i.p. either 3 days before challenge or 3-48 h after challenge.

Gradual solubilization ofCandidacell wall β-glucan by oxidative degradation in mice [PDF]

FEMS Immunology & Medical Microbiology, 1998
Candida spp. is a medically important fungi which induces disseminated candidiasis and candidemia in hospitalized immunocompromised patients. The cell wall of Candida is mainly composed of two polysaccharides, mannan and beta-glucan, and at least part of beta-glucan is basically insoluble in H2O or NaOH. We became interested in when and how particulate

Purification, Preliminary Structural Characterization, and In Vitro Inhibitory Effect on Digestive Enzymes by β-Glucan from Qingke (Tibetan Hulless Barley)

Advances in Polymer Technology, 2020
Background and Objective. Qingke (Tibetan hulless barley, Hordeum vulgare L.) contains a high content of β-glucan among all the cereal varieties. Although β-glucan has multiple physiological functions, the physiological function of qingke β-glucan was ...
