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.

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 gravimetric method for the quantitative determination of soluble β-glucan content in oat grain

Биотехнология и селекция растений, 2021
Background. Oat (Avena sativa L.) is one of the most important sources of protein, oil, starch and dietary fibers, in particular β-glucans. Dietary fiber serves as a source of nutrition for the intestinal microflora and significantly affects not only its

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.

The effects of β-glucan on human immune and cancer cells

Journal of Hematology & Oncology, 2009
Non-prescriptional use of medicinal herbs among cancer patients is common around the world. The alleged anti-cancer effects of most herbal extracts are mainly based on studies derived from in vitro or in vivo animal experiments.

Characterization of an unglycosylated low molecular weight 1,4-β-glucan-glucanohydrolase ofTrichoderma reesei [PDF]

FEMS Microbiology Letters, 1990
A low molecular weight endoglucanase (1,4-beta-glucan glucanohydrolase E.C.3.2.1.4) was purified to homogeneity by a two-step procedure from 7 day old culture filtrates of Trichoderma reesei. The endoglucanase was obtained by BioGel A 0.5 m gel chromatography followed by preparative PAGIF. The purified endoglucanase was homogeneous upon titration curve

β-Glucan Metabolic and Immunomodulatory Properties and Potential for Clinical Application

Journal of Fungi, 2020
β-glucans are complex polysaccharides that are found in several plants and foods, including mushrooms. β-glucans display an array of potentially therapeutic properties. β-glucans have metabolic and gastro-intestinal effects, modulating the gut microbiome,

Stimulation of human neutrophil phagocytosis ofCandida albicansby a β-glucan synthase inhibitor, cilofungin [PDF]

FEMS Microbiology Letters, 1991
The effect of a lipopeptide antifungal agent, cilofungin, on serum opsonization and phagocytosis of Candida albicans yeast phase cells in human neutrophil monolayer assays was investigated. Simultaneous addition of fungicidal concentrations of cilofungin did not enhance or inhibit phagocytosis of C. albicans.
