Recognition of microbial components via innate receptors including the C-type lectin receptor Dectin-1, together with the inflammatory environment, programs dendritic cells (DCs) to orchestrate the magnitude and type of adaptive immune responses. The exposure to β-glucan, a known Dectin-1 agonist and component of fungi, yeasts, and certain immune support supplements, activates DCs to induce T h...
The nose and mouth are the first regions of the respiratory tract in contact with airborne microorganisms. Occupational exposures to airborne microorganisms are associated with inflammation and different symptoms of the airways. The purpose of this study is to investigate the relation between occupational exposure to fungi, β-glucan, and bacteria and contents of fungi, β-glucan, and bacteria in...
Pneumocystis pneumonia (PCP) caused by Pneumocystis jirovecii is one of the most common opportunistic infections in immunosuppressed patients, particularly in patients with acquired immunodeficiency syndrome (AIDS). (1 → 3)-β-D-glucan is a component of the cell wall of P. jirovecii and other fungi such as Candida sp., Aspergillus sp. and Histoplasma sp. The measurement of serum (1 → 3)-β-D-gluc...
The objective was to study the cause of variation in digestibility of mixed linked β(1-3;1-4)-D-glucan (β-glucan) in the small intestine of growing pigs. The β-glucan is an important cell wall [dietary fiber (DF)] component of the endosperm of barley (Hordeum vulgare) and oats (Avena sativa). The digestibility of β-glucan in the small intestine from both cereals is among the highest of all DF c...
Preventive and early therapeutic effects of β-glucan on the bleomycin-induced lung fibrosis in rats.
OBJECTIVE The β-glucans are long-chain polymers of glucose, which comprise the fungal cell wall, stimulate cells of the innate immune system, enhance disturbed epithelization, and have antioxidant effects. Oxidative stress has been implicated in the pathogenesis of bleomycin-induced lung fibrosis and various antioxidant agents have been studied for prevention and treatment of the disease. In th...
Oat mixed-linkage β-glucan has been shown to lower fasting blood cholesterol concentrations due notably to an increase in digesta viscosity in the proximal gut. To exert its action, the polysaccharide has to be released from the food matrix and hydrated. The dissolution kinetics of β-glucan from three oat materials, varying in their structure, composition and degree of processing, was investiga...
UNLABELLED (See the editorial commentary by Morris and Masur, on pages 203-204.) BACKGROUND Improved noninvasive diagnostic tests for Pneumocystis jirovecii pneumonia (PCP) are needed. We evaluated the test characteristics of plasma (1 → 3)-β-D-glucan (β-glucan) for HIV-related PCP among a large group of patients presenting with diverse opportunistic infections (OIs). METHODS The study popu...
Journal of Immunology. Dec 2006; 177: 8667 – 8675 Candida albicans is a common cause of nosocomial infections whose virulence depends on the reversible switch from blastoconidia to hyphal forms. Neutrophils (or polymorphonuclear leukocytes (PMNs)) readily clear blastoconidia by phagocytosis, but filaments are too long to be ingested. Mechanisms regulating immune recognition and response to fila...
Addition of the antifungal antibiotic papulacandin B to an exponential culture of Geotrichum lactis inhibited incorporation of glucose into the alkali-insoluble and alkali-soluble glucan fractions of the hyphal wall, although the rate of growth was practically unaltered. Synthesis of other cell wall components (i.e. galactomannan and chitin) was not affected. Papulacandin B also induced the pro...
