β-glucan (polysaccharide) rich diet has been reported to enhance cognition in humans but the mechanism remained elusive. Keeping this in mind, the present study was designed to investigate the interaction of β-glucan with central cholinergic system. Briefly, in-silico analysis revealed promising interactions of β-glucan with the catalytic residues of acetylcholinesterase (AChE) enzyme. In line ...
The effect of pre- or posttreatment with glucan, a reticuloendothelial stimulant, on the course of Leishmania donovani infection was assessed in highly susceptible hamsters. Intravenous administration of glucan before or after L. donovani infection significantly suppressed proliferation of amastigote-stage parasites in liver and spleen. Glucan-activated peritoneal macrophages in vitro also sign...
The impact of beta-glucan molecular weight (MW) on in vitro bile-acid binding and in vitro fermentation with human fecal flora was evaluated. beta-Glucan extracted from oat line 'N979-5-4' was treated with lichenase (1,3-1,4-beta-D-glucanase) to yield high (6.87x10(5) g/mol), medium (3.71x10(5) g/mol), and low (1.56x10(5) g/mol) MW fractions. The low MW beta-glucan bound more bile acid than did...
BACKGROUND Beta-1-3 Glucan is a polysaccharide extracted from Saccharomyces cerevisiae with a possible immunomodulating action that may have a favourable action on asthma symptoms and other allergic diseases. An experimental study carried out using a murine respiratory model detected a decrease in pulmonary tissue eosinophilia, as well as an increase in Interleukin-10 (IL-10) after glucan use. ...
The protective efficacy of glucan as an adjuvant with killed promastigotes of Leishmania donovani was compared with that of soluble or particulate fractions of the parasite. When these vaccine preparations were injected either intravenously or subcutaneously in CF-1 mice, glucan potentiated resistance against L. donovani infections as reflected by significant reductions in hepatic amastigote co...
In vitro fermentabilities of the oat flour digestion residues (ODR) from two commercial oat lines with 4.7 and 5.3% β-glucan and from two high-β-glucan experimental lines with 7.6 and 8.1% β-glucan were evaluated and compared with fermentations of lactulose, purified oat β-glucan (POBG), and purified oat starch (POS). Substrates were fermented by using an in vitro batch fermentation system unde...
A receptor for beta-glucan was in the present study shown to mediate binding of zymosan particles to resident mouse peritoneal macrophages. Lysosomal enzyme secretion in response to zymosan was maximal at a low particle/cell ratio, continuous for at least 3 h after particle/cell contact and inhibitable by soluble glucan. Latex particles of various size caused no selective secretory response, bu...
The cereal cell wall polysaccharide (1-3,1-4)-b-glucan is a linear polymer of glucose containing both b1-3 and b1-4 bonds. The structure of (1-3,1-4)-b-glucan varies between different cereals and during plant growth and development, but little is known about how this is controlled. The cellulose synthase–like CslF6 protein is an integral membrane protein and a major component of the (1-3,1-4)-b...
Soybean insoluble fractions recovered from aqueous extraction processing (AEP) and enzyme-assisted AEP (EAEP) of full-fat soybean flakes (FFSF) and extruded FFSF were evaluated as a feedstock for the production of fermentable sugars using enzymes. Among the four insoluble fractions (AEP FFSF, EAEP FFSF, AEP extruded FFSF and EAEP extruded FFSF), the composition analysis revealed that the one re...
