Abstract White-button ( Agaricus bisporus ) and shiitake Lentinula edodes mushrooms are widely consumed worldwide because of their organoleptic properties but also bioactive compounds such as β-glucans, ergosterol, phenolic compounds. Although these can be eaten raw food, they usually subjected to household cooking treatments, so effect on the stability molecules was evaluated in this work. The...

Weaning in young animals is associated with an increased incidence of gastrointestinal infections. β-glucans exert numerous physiological effects, including altering immune function. The objective of this study was to determine the effects of feeding barley (Hordeum vulgare L.)-derived β-glucans on immune and intestinal function in weanling pigs (Sus scrofa). Thirty-one individually-housed Dutc...

In the horseshoe crab, the recognition of beta-1,3-D-glucans by factor G triggers hemolymph coagulation. Factor G contains a domain of two tandem xylanase Z-like modules (Z1-Z2), each of which recognizes beta-1,3-D-glucans. To gain an insight into the recognition of beta-1,3-D-glucans from a structural view point, recombinants of Z1-Z2, the C-terminal module Z2, Z2 with a Cys to Ala substitutio...

BACKGROUND Indoor air quality has an effect on respiratory health. Children are more vulnerable to a decreased indoor air quality as their lungs are still developing. We measured levels of allergens and β-(1,3)-glucans in 19 school buildings and determined whether measured levels could be reproduced. School levels were compared to those in 169 homes and the effect of building characteristics on...

Intestinal epithelial cells (IECs) are the first to encounter luminal antigens and play an active role in intestinal immune responses. We previously reported that β-glucans, major fungal cell-wall glycans, induced chemokine secretion by IEC lines a Dectin-1- Syk-dependent manner. Here, we show contrast stimulation of with Candida albicans Saccharomyces cerevisiae did not induce any proinflammat...

Candida albicans and mutans streptococci are frequently detected in dental plaque biofilms from toddlers afflicted with early childhood caries. Glucosyltransferases (Gtfs) secreted by Streptococcus mutans bind to saliva-coated apatite (sHA) and to bacterial surfaces, synthesizing exopolymers in situ, which promote cell clustering and adherence to tooth enamel. We investigated the potential role...

The composition of cell walls in cereal grains and other grass species differs markedly from walls in seeds of other plants. In the maternal tissues that surround the embryo and endosperm of the grain, walls contain higher levels of cellulose and in many cases are heavily lignified. This may be contrasted with walls of the endosperm, where the amount of cellulose is relatively low, and the wall...

73 Behçet’s disease (BD) is a systemic disease of unknown etiology that mostly affects oral and genital mucosa and eyes [1]. B-glucans are long-chain polymers of glucose in β-(1,3)(1,6) linkages that stimulate cells of the innate immune system [2]. In recent years, the use of β-glucans as natural immune stimulant agents has become very popular in Turkey. We report a case of BD, which was possib...
