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.

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.

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.

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.

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.

Association of immunological disorders in lethal side effect of NSAIDs on β-glucan-administered mice [PDF]

FEMS Immunology & Medical Microbiology, 2001
(1-->3)-beta-D-Glucan (beta-glucan) is a biological response modifier that regulates host immune response. We have found that the combination of a beta-glucan and a non-steroidal anti-inflammatory drug (NSAID), indomethacin (IND), induced lethal toxicity in mice [Yoshioka et al. (1998) FEMS Immunol. Med. Microbiol., 21, 171-179].

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

A genome wide association scan for (1,3;1,4)-β-glucan content in the grain of contemporary 2-row Spring and Winter barleys [PDF]

, 2014
Background: (1,3;1,4)-β-Glucan is an important component of the cell walls of barley grain as it affects processability during the production of alcoholic beverages and has significant human health benefits when consumed aboverecommended threshold levels.

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.

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 ...
