Antigen-specific response of murine immune system toward a yeast β-glucan preparation, zymosan [PDF]

FEMS Immunology & Medical Microbiology, 1999
Zymosan, a particulate beta-glucan preparation from Saccharomyces cerevisiae, shows various biological activities, including anti-tumor activity. We have previously shown that soluble beta-glucan initiated anti-tumor activity was long-lived and was effective even by prophylactic treatment at 1 month prior to tumor challenge.

Effect of acid hydrolysis on the structural and antioxidant characteristics of β-glucan extracted from Qingke (Tibetan hulless barley)

Frontiers in Nutrition, 2022
In this study, we explored the effect of acid hydrolysis on the molecular, structural, rheological, thermal, and antioxidant characteristics of Qingke β-glucan. The acid hydrolysis reduced the molecular weights of β-glucans from 510 to 155 KDa.

Isolation and characterization of periplasmic cyclic β-glucans ofAzorhizobium caulinodans [PDF]

FEMS Microbiology Letters, 2003
Oligoglucose molecules isolated from Azorhizobium caulinodans were characterized by compositional analysis, Smith degradation, matrix-assisted laser desorption/ionization time of flight mass spectrometry, and (1)H and (13)C nuclear magnetic resonance analysis. A.

A Review on the Structure and Anti-Diabetic (Type 2) Functions of β-Glucans

Foods, 2021
Type 2 diabetes, a long-term chronic metabolic disease, causes severe and increasing economic and health problems globally. There is growing evidence that β-glucans can function as bioactive macromolecules that help control type 2 diabetes with minimal ...

Soluble mannan and β-glucan inhibit the uptake ofMalassezia furfurby human monocytic cell line, THP-1 [PDF]

FEMS Immunology & Medical Microbiology, 1998
The uptake of live and heat-killed Malassezia furfur HIC 3321, HIC 3343 and Candida albicans ATCC 10231 by human monocytic cell line, THP-1, was examined. THP-1 was differentiated by PMA for 7 days before use. The uptake of these yeasts by THP-1 was increased in a concentration-dependent manner of yeasts, and the uptake reached plateau level at the E/T

Research Progress on the Mechanism and Structure-Activity Relationship of β-Glucans in Regulating the Health Effects of Gut Microbiota [PDF]

Shipin Kexue
β-Glucans, dietary polysaccharides coming from a wide variety of sources, have been researched intensively. Being resistant to oral and gastrointestinal digestion, β-glucans can reach the colon where they are fermented by the gut microbiota, generating ...

Structures, Biosynthesis, and Physiological Functions of (1,3;1,4)-β-d-Glucans

Cells, 2021
(1,3;1,4)-β-d-Glucans, also named as mixed-linkage glucans, are unbranched non-cellulosic polysaccharides containing both (1,3)- and (1,4)-β-linkages.

β-glucans and eicosapolyenoic acids as MAMPs in plant–oomycete interactions: past and present [PDF]

Frontiers in Plant Science, 2015
Branched β-1,3-glucans and the eicosapolyenoic acids (EP) are among the best characterized oomycete elicitors that trigger innate immune responses in plants. These elicitors were identified over three decades ago, and they were useful in the study of the sequence of physiological, biochemical and molecular events that induce resistance in plants ...

Overview of (1→3)-β-D-glucan immunobiology

Mediators of Inflammation, 1997
Glucans are (1→3)-β-D-glucose polymers that are found in the cell wall of fungi, bacteria and plants. Glucans are known to stim ulate humoral and cell-mediated immunity in humans and animals.
