Production of oxygen-derived free radicals in phagocytes is important in preventing bacterial and fungal infections. Among free radicals, superoxide anions are a typical reactive oxygen species secreted by macrophages and neutrophils. NADPH oxidase (NOX) is a key producer of superoxide anions in these cells. β-glucans from mushrooms modulate the immune system by binding with the dectin-1 receptor on macrophages. Dectin-1 functions as a pattern recognition receptor that recognizes the pathogen-associated molecular pattern of β-glucans...

The incidence of vitamin D deficiency has increased in recent years, mainly in Europe. The consumption of processed mushrooms may play an important role in preventing diseases associated with vitamin D deficiency. We determined the effects of 2 kinds of freezing (blast, cryogenic), canning (mild and strong brine), and drying (air-drying, freeze-drying) on the retention of vitamin D2 and ergosterol in Agaricus bisporus. Fresh and processed A. bisporus mushrooms can be a good dietary source of vitamin D2. After 12 months of storage, canned mushrooms retained the largest amount of vitamin D2 and ergosterol, whereas the smallest amount was retained in dried mushrooms...

In vivo and in vitro treatments were carried out to investigate the effects of a 95% ethanol extract of Chroogomphus rutilus (CRE) on antioxidant, hypoglycemic, hypolipidemic, and antitumor properties. CRE showed potent radical scavenging activity against DPPH in vitro. It could increase antioxidant enzymatic activities (superoxide dismutase and glutathione peroxidase) and could reduce malondialdehyde content in vivo in mice in which aging was induced by D-galactose. CRE had hypoglycemic activity and could significantly inhibit α-glucosidase activity in vitro and decrease blood glucose concentration in vivo...

Water extracts from Pleurotus ostreatus containing no statins showed 3-hydroxy-3-methyl-glutaryl CoA reductase (HMGCR) inhibitory activity (in vitro) that might be due to specific water-soluble polysaccharides (WSPs); when isolated and deproteinized, increasing concentrations of the WSP extract induced higher inhibition. The WSP extract contained mainly β-glucans, mannogalactans, and glycogen (e.g., α-glucans), although derivatives or fragments with lower molecular weights (between 14 and 3.5 kDa) were present and were able to induce the inhibitory activity...
