Heliyon 2024; 10:e29444. [PMID: 38628769 PMCID: PMC11019199 DOI: 10.1016/j.heliyon.2024.e29444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 04/05/2024] [Accepted: 04/08/2024] [Indexed: 04/19/2024] Open
Abstract
Fragmentation of β-glucans secreted by the fungus Ophiocordyceps dipterigena BCC 2073 achieved by microfluidization was investigated. The degree of β-glucan fragmentation was evaluated based on the average number of chain scissions (α). The effects on the α value of experimental variables like solid concentration of the β-glucan suspension, interaction chamber pressure, and number of passes through the microfluidizer were examined. Kinetic studies were conducted using the relationships of the α and suspension viscosity values with the number of passes. Evidence indicated that α increases with the interaction chamber pressure and the number of passes, whereas the solid concentration shows the inverted effect. Kinetic data indicated that the fragmentation rate increases with β-glucan solid concentration and interaction chamber pressure. Furthermore, since β-glucan molecular weight is a key factor determining its biological activity, the effect of β-glucans of different molecular weights produced by fragmentation on tumor necrosis factor (TNF)-α-stimulating activity in THP-1 human macrophage cells was investigated. Evidence suggested that β-glucans have an immunostimulating effect on macrophage function, in the absence of cytotoxic effects. Indeed, β-glucans characterized by a range of molecular weights produced via microfluidization exhibited promise as immunostimulatory agents.

Abstract
This study aimed to investigate the structural characterization of water-soluble polysaccharides from Sparassis crispa and their effects on the proliferation and differentiation of mouse osteoblasts. Three fractions (F-1, F-2, and F-3) were obtained from crude polysaccharides by a DEAE-52 cellulose column. The main fraction (F-1) was further purified by polysaccharide gel purification systems to obtain purified water-soluble Sparassis crispa polysaccharide (SCPS). The chemical structure of SCPS was analyzed by gas chromatography, Fourier transform infrared spectroscopy, methylation analysis, and nuclear magnetic resonance spectroscopy. The monosaccharide compositional analysis revealed that SCPS consisted of fucose, arabinose, galactose, glucose, xylose, mannose, ribose, galacturonic acid, glucuronic acid, and mannuronic acid in a molar ratio of 17.37:1.94:25.52:30.83:1.14:0.30:4.98:2.87:2.65. Moreover, the backbone of SCPS was composed of →3)-β-d-Glcp-(1→4)-β-d-Glcp-(1→, with side chains attached to the backbone at the O-6 positions through the →3,6)-β-d-Glcp-(1→ linkage. The in vitro experiments were conducted to investigate the effects of SCPS on the proliferation and differentiation of mouse osteoblasts. The results showed that SCPS significantly enhanced the proliferation and differentiation of mouse osteoblasts, indicating their potential as a pharmaceutical agent for promoting osteoblast proliferation and differentiation.

Abstract
A low molecular weight polysaccharides of HEP-1, with molecular weights of 1.67 × 104 Da and composition of →6)-β-D-Glcp-(1→, →3)-β-D-Glcp-(1→, β-D-Glcp-(1→ and →3,6)-β-D-Glcp-(1→, was isolated and characterized from the fruiting body of Hericium erinaceus. The results indicated that HEP-1 showed potential effects against T2DM-induced imbalance of glucose and lipid metabolism by promoting the serum glucose uptake by hepatic glycogen synthesis via activating the IRS/PI3K/AKT signaling pathway, and inhibiting fatty acid synthesis and reducing hepatic lipid accumulation via activating the AMPK/SREBP-1c signaling pathways. Besides, HEP-1 promoted the production of beneficial bacteria in the gut, and increased the beneficial metabolites in liver through the gut-liver axis, consequently, resisting the occurrence of T2DM.

Abstract
OL-2 is a water-soluble β-glucan produced by Omphalia lapidescens. This versatile glucan has potential applications in various industries, including food, cosmetics, and pharmaceuticals. In addition, OL-2 is known for its promising applications as a biomaterial and drug, owing to its reported antitumor and antiseptic properties. Although the biological activities of β-glucans vary depending on their primary structure, holistic clarification of OL-2 via solution NMR spectroscopy to ascertain its complete and unambiguous structure has not yet been achieved. In this study, a chain of solution NMR techniques, such as correlation spectroscopy, total correlation spectroscopy (TOCSY), nuclear Overhauser effect and exchange spectroscopy, 13C-edited heteronuclear single quantum coherence (HSQC), HSQC-TOCSY, heteronuclear multiple bond correlation, and heteronuclear 2-bond correlation pulse sequences were used to unambiguously assign all 1H and 13C atoms in OL-2. Based on our investigation, OL-2 consists of a 1,3-β-glucan backbone chain decorated with a single 6-branched β-glucosyl side unit on every fourth residue.

Abstract
Two pectins from the seagrass Enhalus acoroides (L.f.) Royle were isolated for the first time. Their structures and biological activities were investigated. NMR spectroscopy showed one of them to consist exclusively from the repeating →4-α-d-GalpUA→ residue (Ea1), while the other had a much more complex structure that also included 1→3-linked α-d-GalpUA residues, 1→4-linked β-apiose residues and small amounts of galactose and rhamnose (Ea2). The pectin Ea1 showed noticeable dose-dependent immunostimulatory activity, the Ea2 fraction was less effective. Both pectins were used to create pectin-chitosan nanoparticles for the first time, and the influence of pectin/chitosan mass ratio on their size and zeta potential was investigated. Ea1 particles were slightly smaller than Ea2 particles (77 ± 16 nm vs 101 ± 12 nm) and less negatively charged (-23 mV vs -39 mV). Assessment of their thermodynamic parameters showed that only the second pectin could form nanoparticles at room temperature.

The Effect of Mushroom Culture Filtrates on the Inhibition of Mycotoxins Produced by Aspergillus flavus and Aspergillus carbonarius. Toxins (Basel) 2023; 15:toxins15030177. [PMID: 36977069 PMCID: PMC10052992 DOI: 10.3390/toxins15030177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 02/16/2023] [Accepted: 02/22/2023] [Indexed: 03/02/2023] Open
Abstract
Two of the mycotoxins of greatest agroeconomic significance are aflatoxin B1 (AFB1), and ochratoxin A (OTA). It has been reported that extracts from some wood-decaying mushrooms, such as Lentinula edodes and Trametes versicolor showed the ability to inhibit AFB1 or OTA biosynthesis. Therefore, in our study, a wide screening of 42 isolates of different ligninolytic mushrooms was assayed for their ability to inhibit the synthesis of OTA in Aspergillus carbonarius and AFB1 in Aspergillus flavus, in order to find a metabolite that can simultaneously inhibit both mycotoxins. The results showed that four isolates produce metabolites able to inhibit the synthesis of OTA, and 11 isolates produced metabolites that inhibited AFB1 by >50%. Two strains, the Trametes versicolor strain TV117 and the Schizophyllum commune strain S.C. Ailanto, produced metabolites able to significantly inhibit (>90%) the synthesis of both mycotoxins. Preliminary results suggest that the mechanism of efficacy of the S. commune rough and semipurified polysaccharides could be analogous to that found previously for Tramesan®, by enhancing the antioxidant response in the target fungal cells. The overall results indicate that S. commune’s polysaccharide(s) could be a potential agent(s) in biological control and/or a useful component of the integrated strategies able to control mycotoxin synthesis.

Abstract
Fungal polysaccharide is a kind of biomacromolecule with multiple biological activities, which has a wide application prospect and may play an important role in organisms to cope with extreme environments. Herein, we reported an extracellular polysaccharide (EPS) produced by Schizophyllum commune 20R-7-F01 that was isolated from subseafloor sediments at ~2 km below the seafloor, obtained during expedition 337. The monosaccharide of EPS was glucose and its molecular weight was 608.8 kDa. Methylation and NMR analysis indicated that the backbone of the EPS was (1 → 3)-β-D-glucan with a side chain (1 → 6) β-D-glucan linking at every third residue. Bio-active assays revealed that the EPS had potent antioxidant activity and could promote RAW264.7 cells viability and phagocytosis. These results suggest that fungi derived from sediments below seafloor are important and new source of polysaccharides and may be involved in the adaptation of fungi to anoxic subseafloor extreme ecosystem.

Abstract
Sparassis crispa is an edible mushroom exhibiting a wide range of medicinal properties. It is recognized for therapeutic value because of the high β-glucan content in the basidiomes. The broad range of its reported curative effects include anti-tumour, anti-cancer, immune-enhancing, hematopoietic, anti-angiogenic, anti-inflammatory, anti-diabetic, wound-healing, antioxidant, anti-coagulant, and anti-hypertensive properties. However, most of the studies are conducted on immunomodulatory and anticancer activities. Besides this, it also exhibits anti-microbial properties due to the presence of sparassol. Technology is now available for the cultivation of S. crispa on coniferous sawdust. This review is an attempt to focus on its distribution, taxonomy, chemical composition, medicinal properties, potential applications, and artificial cultivation.

Abstract
The cell wall polysaccharides were extracted from Sparassis latifolia fruit bodies by acid–alkali and superfine-grinding assisted methods, and the chemical characterization and in vitro immunity activities of these polysaccharide fractions were studied and compared. Results showed that superfine-grinding assisted extraction exhibited the highest yield of polysaccharides (SP, 20.80%) and low β-glucan content (19.35%) compared with alkaline extracts. The results revealed that the 20% ethanol precipitated fraction (20E) from SP was mainly composed of β-(1→3)-glucan and α-(1→4)-glucan. With the increase of ethanol precipitation, the fractions (30E, 40E, 50E) were identified as α-(1→4)-glucan with different molecular weights and conformations. Cell wall polysaccharides extracted through NaOH (NSP) and KOH (KSP) extraction had similar yields with 8.90% and 8.83%, respectively. Structural analysis indicated that the purified fraction from KSP (KSP-30E) was a β-(1→3)-glucan backbone branched with β-(1→6)-Glcp, while the purified fraction from NSP (NSP-30E) mainly contained β-(1→3)-glucan with a small number of α-linked-Glcp. The two fractions both exhibited rigid chain conformation in aqueous solutions. All polysaccharide fractions exerted the activity of activating Dectin-1 receptor in vitro, and the KSP-30E mainly identified as β-(1→3)-glucan with the terminal group via 1→6-linkage attached at every third residue exhibited a stronger enhancing effect than other fractions. Results suggested that KOH extraction could be efficient for the preparation of bioactive β-(1→3, 1→6)-glucan as a food ingredient.

Abstract
In the present study, a purified polysaccharide (named SCP-1, Mw 1.368 × 104 Da) was isolated from Sparassis crispa, and its biological activity was evaluated in an oxidative stress model caused by H2O2 in hippocampal neuronal HT22 cells. SCP-1 was a heteropolysaccharide mainly comprising glucose, galactose, fucose, and mannose in a molar ratio of 52.10: 31.10: 15.04: 1.76. The main backbone of SCP-1 was predominantly composed of (1→6)-α-D-Galp, (1→6)-β-D-Glcp, (1→3)-β-D-Glcp, (1→2,6)-α-D-Galp and (1→3,6)-β-D-Glcp. The branches, substituted at the O-2 of Gal and O-3 of Glc, contained (1→6)-2-OMe-α-D-Galp, (1→4)-β-D-Glcp, (1→3)-β-D-Glcp, and terminated by T-α-L-Fucp and T-β-D-Glcp. Besides, SCP-1 could effectively protect the HT22 cells against H2O2-induced oxidative injury via decreasing the intracellular reactive oxygen species levels, modulating antioxidant enzymes, and reducing cell apoptosis. The findings suggested that SCP-1 holds a potential to be a natural antioxidant or as a neuroprotective agent.

Abstract
Fungi are eukaryotic microorganisms that show complex life cycles, including both anamorph and teleomorph stages. Beta-1,3-1,6-glucans (BGs) are major cell wall components in fungi. BGs are also found in a soluble form and are secreted by fungal cells. Studies of fungal BGs extensively expanded from 1960 to 1990 due to their applications in cancer immunotherapy. However, progress in this field slowed down due to the low efficacy of such therapies. In the early 21st century, the discovery of C-type lectin receptors significantly enhanced the molecular understanding of innate immunity. Moreover, pathogen-associated molecular patterns (PAMPs) and pattern recognition receptors (PRRs) were also discovered. Soon, dectin-1 was identified as the PRR of BGs, whereas BGs were established as PAMPs. Then, studies on fungal BGs focused on their participation in the development of deep-seated mycoses and on their role as a source of functional foods. Fungal BGs may have numerous and complex linkages, making it difficult to systematize them even at the primary structure level. Moreover, elucidating the structure of BGs is largely hindered by the multiplicity of genes involved in cell wall biosynthesis, including those for BGs, and by fungal diversity. The present review mainly focused on the characteristics of fungal BGs from the viewpoint of structure and immunological activities.

BMC Biotechnol 2021; 21:28. [PMID: 33773573 PMCID: PMC8005236 DOI: 10.1186/s12896-021-00688-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 03/15/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Microbial polysaccharides have been reported to possess remarkable bioactivities. Physarum polycephalum is a species of slime mold for which the microplasmodia are capable of rapid growth and can produce a significant amount of cell wall-less biomass. There has been a limited understanding of the polysaccharides produced by microplasmodia of slime molds, including P. polycephalum. Thus, the primary objectives of this research were first to chemically characterize the exopolysaccharides (EPS) and intracellular polysaccharides (IPS) of P. polycephalum microplasmodia and then to evaluate their cytotoxicity against several cancer cell lines. RESULTS The yields of the crude EPS (4.43 ± 0.44 g/l) and partially purified (deproteinated) EPS (2.95 ± 0.85 g/l) were comparable (p > 0.05) with the respective crude IPS (3.46 ± 0.36 g/l) and partially purified IPS (2.45 ± 0.36 g/l). The average molecular weight of the EPS and IPS were 14,762 kDa and 1788 kDa. The major monomer of the EPS was galactose (80.22%), while that of the IPS was glucose (84.46%). Both crude and purified IPS samples showed significantly higher cytotoxicity toward Hela cells, especially the purified sample and none of the IPSs inhibited normal cells. Only 38.42 ± 2.84% Hela cells remained viable when treated with the partially purified IPS (1 mg/ml). However, although only 34.76 ± 6.58% MCF-7 cells were viable when exposed to the crude IPS, but the partially purified IPS displayed non-toxicity to MCF-7 cells. This suggested that the cytotoxicity toward MCF-7 would come from some component associated with the crude IPS sample (e.g. proteins, peptides or ion metals) and the purification process would have either completely removed or reduced amount of that component. Cell cycle analysis by flow cytometry suggested that the mechanism of the toxicity of the crude IPS toward MCF-7 and the partially purified IPS toward Hela cells was due to apoptosis. CONCLUSIONS The EPS and IPS of P. polycephalum microplasmodia had different chemical properties including carbohydrate, protein and total sulfate group contents, monosaccharide composition and molecular weights, which led to different cytotoxicity activities. The crude and partially purified IPSs would be potential materials for further study relating to cancer treatment.

Abstract
β-Glucan is widely distributed in various plants and microorganisms and is composed of β-1,3-linked d-glucose units. It may have a branched short or long side chain of glucose units with β-1,6- or β-1,4-linkage. Numerous studies have investigated different β-glucans and revealed their bioactivities. To understand the structure-function relationship of β-glucan, we constructed a split-luciferase complementation assay for the structural analysis of long-chain β-1,6-branched β-1,3-glucan. The N- and C-terminal fragments of luciferase from deep-sea shrimp were fused to insect-derived β-1,3-glucan recognition protein and fungal endo-β-1,6-glucanase (Neg1)-derived β-1,6-glucan recognition protein, respectively. In this approach, two β-glucan recognition proteins bound to β-glucan molecules come into close proximity, resulting in the assembly of the full-length reporter enzyme and induction of transient luciferase activity, indicative of the structure of β-glucan. To test the applicability of this assay, β-glucan and two β-glucan recognition proteins were mixed, resulting in an increase in the luminescence intensity in a β-1,3-glucan with a long polymer of β-1,6-glucan in a dose-dependent manner. This simple test also allows the monitoring of real-time changes in the side chain structure and serves as a convenient method to distinguish between β-1,3-glucan and long-chain β-1,6-branched β-1,3-glucan in various soluble and insoluble β-glucans.

Promising Potential of Crude Polysaccharides from Sparassis crispa against Colon Cancer: An In Vitro Study. Nutrients 2021; 13:E161.

Abstract
The aim of the present study was to evaluate in vitro the beneficial potential of crude polysaccharides from S. crispa (CPS) in one of the most common cancer types-colon cancer. The determination of the chemical composition of CPS has revealed that it contains mostly carbohydrates, while proteins or phenolics are present only in trace amounts. 1H NMR and GC-MS methods were used for the structural analysis of CPS. Biological activity including anticancer, anti-inflammatory and antioxidant properties of CPS was investigated. CPS was found to be non-toxic to normal human colon epithelial CCD841 CoN cells. Simultaneously, they destroyed membrane integrity as well as inhibited the proliferation of human colon cancer cell lines: Caco-2, LS180 and HT-29. Antioxidant activity was determined by various methods and revealed the moderate potential of CPS. The enzymatic assays revealed no influence of CPS on xanthine oxidase and the inhibition of catalase activity. Moreover, pro-inflammatory enzymes such as cyclooxygenase-2 or lipooxygenase were inhibited by CPS. Therefore, it may be suggested that S. crispa is a valuable part of the regular human diet, which may contribute to a reduction in the risk of colon cancer, and possess promising activities encouraging further studies regarding its potential use as chemopreventive and therapeutic agent in more invasive stages of this type of cancer.

Abstract
Salvia miltiorrhiza roots (SMRs), the main component of cell wall from the residual waste extraction, differ depending on the forming ways of monosaccharides. The extraction from 8% sodium hydroxide solution (H-8) was characterized by gel permeation chromatography (GPC), monosaccharide composition, Fourier transform infrared spectroscopy (FT-IR), and nuclear magnetic resonance (NMR) spectroscopy. The structure model of hemicellulose-based polysaccharides (HBPs) was derived by combining one-dimensional and two-dimensional NMR. Monosaccharides difference and correlation were performed by partial least square analysis (PLS). Seven H-8s exhibited optimal inhibitory activities, which varied based on different sources of Danshen. The backbone structure indicated that 4-β-D-Xylp served as the main chain connected by 3-α-L-Araf or 5-α-L-Araf-1, 4-β-D-Galp, and β-D-Glcp branch, as well as α-L-Rhap, α-D-GalpA and α-D-GlcpA fragments. The variation of HBPs in terms of the structure and bioactivity of SMRs correlated with different cultivation sites can be a new approach to optimize and utilize the medical materials by chemical and biological aspects of natural macromolecules.

Abstract
This study aimed to investigate the elicitation effects of alginate oligosaccharides extracted from brown algae (Sargassum species) on β-glucan production in cauliflower mushroom (Sparassis latifolia). Sodium alginate was refined from Sargassum fulvellum, S. fusiforme, and S. horneri, and characterized by proton nuclear magnetic resonance spectroscopy (1H NMR), resulting mannuronic acid to guluronic acid (M/G) rationes from 0.64 to 1.38. Three oligosaccharide fractions, ethanol fraction (EF), solid fraction (SF), and liquid fraction (LF), were prepared by acid hydrolysis and analyzed by Fourier transform infrared (FT-IR) spectra and high-performance anion-exchange chromatography with a pulsed amperometric detector (HPAEC-PAD). The samples of S. fusiforme resulted in the highest hydrolysate in SF and the lowest in LF, which was consistent with its highest M/G ratio. The SF of S. fusiforme and LF of S. horneri were chosen for elicitation on S. latifolia, yielding the highest β-glucan contents of 56.01 ± 3.45% and 59.74 ± 4.49% in the stalk, respectively. Total polyphenol content (TPC) and antioxidant activities (2,2’-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging and Superoxide dismutase (SOD)-like activity) of aqueous extracts of S. latifolia were greatly stimulated by alginate elicitation. These results demonstrate that alginate oligosaccharides extracted from brown algae may be useful as an elicitor to enhance the nutritional value of mushrooms.

Abstract
It is known that a well-functioning immune system is important for human health. There are many natural and synthetic preparation that are widely used as immunomodulators. One such natural preparat is β-glucan. Beta-glucans are a group of natural polysaccharides. They are recognized as an effective immunocorrector. Their use is advisable both for the prevention of immunodeficiency pathologies and for the complex treatment of many diseases from cardiovascular to oncological. The physiological activity of β-glucan depends on the type and configuration between monosaccharide residues, branching and conformation of macromolecules, solubility in water. One major source of β-glucan is the baker’s yeast Saccharomyces cerevisiae. Much research has been carried out over the years examining cell wall glucans from Saccharomyces cerevisiae. This work is the development devoted to the characterization of water-soluble beta-glucan obtained as a result of controlled degradation with the enzyme Rovabio Excel AP of glucan cell walls of yeast Saccharomyces cerevisiae. In this study conditions were selected which allow to accumulate the maximum water-soluble fractions with a molecular mass of 1–30 kDa presumably as fractions with a high immunomodulatory effect. The results of the paper show that glucan can be isolated from Saccharomyces cerevisiae in very pure form by the method used in this study. Thus structural analysis gives reliable results. The structural characterization of pure product was performed using the common analytical procedures: enzymes hudrolyses and spectral analyses FTIR, NMR spectroscopy. On the basis of the obtained results it was concluded that investigated glucan is a (1→3)-β-linked glucose polymer with (1→6)-β-linked side chains with sparsely branched. Further work will concern the physiological effect of water-soluble glucan in comparision to the native glucan. The structural requirements for example for an immunomodulation in humans or animals are still under discussion.

Abstract
β-1,3-d-Glucan is a ubiquitous glucose polymer produced by plants, bacteria, and most fungi. It has been used as a diagnostic tool in patients with invasive mycoses via a highly-sensitive reagent consisting of the blood coagulation system of horseshoe crab. However, no method is currently available for measuring β-1,6-glucan, another primary β-glucan structure of fungal polysaccharides. Herein, we describe the development of an economical and highly-sensitive and specific assay for β-1,6-glucan using a modified recombinant endo-β-1,6-glucanase having diminished glucan hydrolase activity. The purified β-1,6-glucanase derivative bound to the β-1,6-glucan pustulan with a KD of 16.4 nm We validated the specificity of this β-1,6-glucan probe by demonstrating its ability to detect cell wall β-1,6-glucan from both yeast and hyphal forms of the opportunistic fungal pathogen Candida albicans, without any detectable binding to glucan lacking the long β-1,6-glucan branch. We developed a sandwich ELISA-like assay with a low limit of quantification for pustulan (1.5 pg/ml), and we successfully employed this assay in the quantification of extracellular β-1,6-glucan released by >250 patient-derived strains of different Candida species (including Candida auris) in culture supernatant in vitro We also used this assay to measure β-1,6-glucan in vivo in the serum and in several organs in a mouse model of systemic candidiasis. Our work describes a reliable method for β-1,6-glucan detection, which may prove useful for the diagnosis of invasive fungal infections.

Abstract
Maitake (Grifola frondosa) mushroom has received an enormous amount of attention as a dietary supplement due to its high nutritional values. The particle sizes of G. frondosa mushrooms were monitored by a classifying mill. β-Glucans are the bioactive component of the mushroom, and it was revealed through Fourier transform infrared spectroscopy (FTIR), proton and carbon nuclear magnetic resonance (1H and 13C-NMR), matrix-assisted laser desorption/ionization, and time-of-flight (MALDI-TOF) spectrometry. The biocompatibility of G. frondosa particles, as well as induced osteogenesis of hMSCs, was evaluated through WST-1 assay and alizarin staining (ARS) technique, respectively. Notably, enhanced cell viability was noted in the presence of G. frondosa. Significantly improved calcium deposition has observed from hMSCs with G. frondosa, suggesting to their mineralization potential. The expression of osteogenic related gene markers was examined in the presence of G. frondosa through real-time polymerase chain reaction (qPCR) technique. The upregulation of osteogenic gene markers in the presence of G. frondosa particles was indicating their superior osteogenic potential. Besides, G. frondosa also activated the secretion of various kinds of proteins from the hMSCs indicating their potential for tissue engineering applications. Enhanced secretion of different immunoglobulins was observed in rat serum in the presence of G. frondosa, further demonstrating their therapeutic nature. Therefore, G. frondosa is effective for enhanced osteogenesis and can be utilized as a natural, edible, and osteogenic agent.

Abstract
In this study, the structure characteristic of the Hericium erinaceus polysaccharide (HEP) was investigated using Fourier transformed infrared spectrometry (FT-IR), gas chromatography-mass spectrometry (GC-MS), gel permeation chromatography (GPC), methylation and nuclear magnetic resonance (NMR). The results showed that HEP, with a molecular weight of 43 KDa, was mainly composed of glucose and rhamnose. The linkages of the sugar residues of HEP were → 6) β-d-Glcp-(1 → and → 2) -α-l-Rhap-(1 → residue at the end of the branches. The Fusarium toxin deoxynivalenol (DON)-induced cellular injury model for IPEC-J2 cells was established and used to investigate the protective effects of HEP against the oxidative stress. The results suggest that HEP could significantly protect IPEC-J2 cells from DON-induced oxidative stress, inhibit DON-induced apoptosis and reduce the production of reactive oxygen species (ROS). Overall, this study suggested that HEP could be explored as potential antioxidant agents for DON-induced intestinal mucosa injury.

Abstract
Beta-glucan (β-glucan) is a macromolecule structure where glucose unit has bonded through β-glycosidic bond at 1 and 3 positions. It is well known as a natural immunomodulator without exhibiting any side effects via enhancing immunity. Mushroom contains a large amount of β-glucan and it has anticancerous and antioxidant efficacy. Structure and physical properties of β-glucan are highly influenced by the types of mushroom. In particular, Grifola frondosa has β-1, 3 and β-1, 6 bonds in their structure. It has been noted that β-glucan content also depends upon the size of mushroom particles. The exact content of β-glucan and their immunological activity by a particle size of G. frondosa have yet to be fully elucidated. Herein, β-glucan contents were analyzed according to the particle size of leaf mushroom followed by cell activation and immunoactivity analysis. The highest β-glucan content was observed at a particle size of 20-30 μm (27.65 ± 0.30 w/w). All samples showed ~ 103% cell activation compared to the control and greater cell activity was observed at higher concentration. The significant increase in cytokines secretion was observed in the presence of 20-30 μm particle size of G. frondosa compared to the control. This study suggested that 20-30 μm size is the suitable size of G. frondosa that can be used as a health supplement and food additive to act as an immune booster, hypotensive agent, and hypoglycemic agent.

Abstract
Sparassis crispa (Wulf.) belonging to the family of Sparassidaceae, has been widely used as an edible mushroom due to its unique flavor and functions to improve health. In this study, the compounds isolated from the extract of this mushroom were simultaneously quantified by the developed HPLC-DAD method and evaluated for the inhibitory activities on the production of the LPS-stimulated cytokines (IL-12p40, IL-6, and TNF-α) in bone marrow-derived dendritic cells (BMDCs). The contents of this compounds were 0.1928 ± 0.0118, 4.4137 ± 0.0240, 0.5237 ± 0.0005, 2.7303 ± 0.0206 mg/g for sparoside A (1), methyl 2,4-dihydroxy-3-methoxy-6-methylbenzoate (2), sparalide A (3), and 5'-deoxy-5'-methylthioadenosine (4), respectively, which demonstrated that they are the major constituents of this mushroom. Thus, our results were found that the sparoside A (1), 5-hydroxy-7-methoxyphthalide (6), 5-methoxy-7-hydroxyphthalide (7), nicotinamide (10), and adenosine (11) inhibit LPS-stimualted cytokine production, compound 6 is the most potent inhibitory activities on the production of IL-12p40, IL-6, and TNF-α with IC50 values of 0.19, 0.18, and 0.91 μM, respectively.

Immunostimulant effects and potential application of β-glucans derived from marine yeast Debaryomyces hansenii in goat peripheral blood leucocytes. Int J Biol Macromol 2018; 116:599-606.

Abstract
Debaryomyces hansenii has been described to be effective probiotic and immunostimulatory marine yeast in fish. Nonetheless, to the best of our knowledge, it has been not assayed in ruminants. This study attempts to describe the immunostimulatory effects of its β-glucan content through in vitro assays using goat peripheral blood leukocytes at 24 h of stimulation. The structural characterization of yeast glucans by proton nuclear magnetic resonance indicated structures containing (1-6)-branched (1-3)-β-D-glucan. In vitro assays using peripheral blood leukocytes stimulated with β-glucans derived from three D. hansenii strains and zymosan revealed that β-glucans significantly increased cell immune parameters, such as phagocytic ability, reactive oxygen species production (respiratory burst), peroxidase activity and nitric oxide production. Antioxidant enzymes revealed an increase in superoxide dismutase and catalase activities in leukocytes stimulated with yeast β-glucans. This study revealed that yeast β-glucans were able to activate dectin-1 mRNA gene expression in leukocytes. The TLR4 gene expression was up-regulated in leukocytes after stimulation with yeast β-glucans. In conclusion, β-glucans were able to modulate the immune system by promoting cell viability, phagocytic activity, antioxidant immune response and immune-related gene expression in leukocytes. Therefore, β-glucans derived from Debaryomyces hansenii should be considered a potential immunostimulant for goat production systems.

β-(1→6)-D-glucan secreted during the optimised production of exopolysaccharides by Paecilomyces variotii has immunostimulatory activity. Antonie van Leeuwenhoek 2017; 111:981-994.

Abstract
Paecilomyces variotii is a filamentous fungus that occurs worldwide in soil and decaying vegetation. Optimization of the fermentation process for exopolysaccharide (EPS) production from the fungus P. variotii, structure determination and immuno-stimulating activity of EPS were performed. Response surface methodology (RSM) coupled with central composite design (CCD) was used to optimize the physical and chemical factors required to produce EPS in submerged fermentation. Preliminary investigations to choose the three factors for the present work were made using a factorial experimental design. Glucose, ammonium nitrate (NH4NO3) and pH were used as variables for which, with constant temperature of 28 °C and agitation of 90 rpm, the optimal process parameters were determined as glucose values of 0.96%, NH4NO3 0.26% and pH 8.0. The three parameters presented significant effects. In this condition of culture, the main composition of the isolated EPS was a linear β-(1 → 6)-linked-D-glucan, as determined by Nuclear Magnetic Resonance (NMR) and methylation analysis. This polysaccharide is a very unusual as an EPS from fungi, especially a filamentous fungus such as P. variotii. Murine peritoneal macrophages cultivated with β-glucan for 6 and 48 h showed an increase in TNF-α, IL-6 and nitric oxide release with increased polysaccharide concentrations. Therefore, we conclude that the β-(1 → 6)-linked-D-glucan produced in optimised conditions of P. variotii cultivation has an immune-stimulatory activity on murine macrophages.

Abstract
β-Glucans are a group of biologically-active fibers or polysaccharides from natural sources with proven medical significance. β-Glucans are known to have antitumor, anti-inflammatory, anti-obesity, anti-allergic, anti-osteoporotic, and immunomodulating activities. β-Glucans are natural bioactive compounds and can be taken orally, as a food supplement, or as part of a daily diet, and are considered safe to use. The medical significance and efficiency of β-glucans are confirmed in vitro, as well as using animal- and human-based clinical studies. However, systematic study on the clinical and physiological significance of β-glucans is scarce. In this review, we not only discuss the clinical and physiological importance of β-glucans, we also compare their biological activities through the existing in vitro and animal-based in vivo studies. This review provides extensive data on the clinical study of β-glucans.

Abstract
Successive chromatography of EtOAc-soluble extracts of the fruiting body of Sparassis crispa (Wulf.) resulted in isolation of four new aromatic compounds, sparoside A (1) and sparalides A-C (3-5), two new naturally occurring compounds, 2 and 6, and eight known compounds, 7-14. The chemical structures were determined by interpretation of nuclear magnetic resonance and mass spectrometry spectroscopic data. Extract, solvent-soluble fractions of the extract, and all of the pure compounds isolated from the fractions were subjected to the mRNA expression assay for proprotein convertase subtilisin/kexin type 9 (PCSK9). Among them, sparoside A (1), hanabiratakelide A (8), adenosine (11), and 5α,6α-epoxy-(22E,24R)-ergosta-8(14),22-diene-3β,7β-diol (14) exhibited potent inhibitory activities on PCSK9 mRNA expression, with IC50 values of 20.07, 7.18, 18.46, and 8.23 μM, respectively (berberine, positive control, IC50 = 8.04 μM), suggesting that compounds 1, 8, 11, and 14 are suitable for use in supplements to the statins for hyperlipidemia treatments.

Abstract
The multidrug resistance (MDR) phenotype is considered as a major cause of the failure in cancer chemotherapy. The acquisition of MDR is usually mediated by the overexpression of drug efflux pumps of a P-glycoprotein. The development of compounds that mitigate the MDR phenotype by modulating the activity of these transport proteins is an important yet elusive target. Here, we screened the saponification and enzymatic degradation products from Salvia hispanica seed's mucilage to discover modulating compounds of the acquired resistance to chemotherapeutic in breast cancer cells. Preparative-scale recycling HPLC was used to purify the hydrolysis degradation products. All compounds were tested in eight different cancer cell lines and Vero cells. All compounds were noncytotoxic at the concentration tested against the drug-sensitive and multidrug-resistant cells (IC50 > 29.2 μM). For the all products, a moderate vinblastine-enhancing activity from 4.55-fold to 6.82-fold was observed. That could be significant from a therapeutic perspective.

Abstract
β-d-glucans are polymers of d-glucose monomers found in the cell walls of many bacteria, plants, fungi and yeasts. A variety of β-d-glucans differing in structures have been isolated from various sources and their biological activity to be regulated by various structural factors, such as the primary structure, molecular weight, solubility, and conformation. This study investigated the effect of extraction time and temperature on the yield of β-d-glucan produced by Rhodotorulamucilaginosa. A statistical Doehlert design was applied to determine the important effects and interactions of these independent variables on the yield of β-d-glucan, the dependent variable. Significant models were obtained. The best yield was of 25% obtained after 128min of extraction in a temperature of 72°C. The polysaccharides were characterized as (1⟶3)-β-d-glucan by methods spectroscopic (FT-IR, (1)HNMR and (13)CNMR). In addition, the antinociceptive effect was evaluated using different experimental tests (acetic acid-induced writhing test, formalin test and tail immersion test). The (1⟶3)-β-d-glucan showed a potent peripheral antinociceptive effect, possibly by the inhibition of inflammatory mediators.

Abstract
Sparassis crispa (SC) is an edible mushroom with various medicinal properties. In this study, we investigated to determine whether SC would affect skin conditions in rats and humans. Oral administration of SC increased both turnover of the stratum corneum and dermal soluble collagen content in collagen synthetic activity-reduced model rats. To investigate the effects of oral intake of SC in humans, we performed a randomized, double-blind, placebo-controlled study. We found that cheek transepidermal water loss was significantly lower in the experimental group than in the control group at 4 weeks of ingestion. This study suggests that SC is effective and safe for the improvement of skin conditions.

Abstract
The structural and physicochemical properties of polysaccharides isolated from fungi with anticancer properties were investigated. The majority of the polysaccharides considered, have the β-d-Glcp component mostly connected by 1→3 and 1→6 linkages in the backbones and the short branches, respectively. The established parameters of lead-like, drug-like and of known dug space (KDS) were used and the repeating units of the polysaccharides exhibit some overlap with these. It was found that a unique region of chemical space is occupied by the polysaccharides, with MW: 1.0 x 10(5) to 2.5 x 10(5) g mol(-1); LogP: -3.0 x 10(3) to -1.0 x 10(3); HD: 1.0 x 10(3) to 5.0 x 10(3); HA: 5.0 x 10(3) to 1.0 x 10(4); PSA: 5.0 x 10(4) to 1.0 x 10(5) and RB: 5.0 x 10(3) to 1.0 x 10(4). These findings can be exploited in antitumor drug discovery projects.

Abstract
Sparassis crispa, also known as cauliflower mushroom, is an edible mushroom with medicinal properties. Its cultivation became popular in Japan about 10 years ago, a phenomenon that has been attributed not only to the quality of its taste, but also to its potential for therapeutic applications. Herein, I present a comprehensive summary of the pharmacological activities and mechanisms of action of its bioactive components, such as beta-glucan, and other physiologically active substances. In particular, the immunomodulatory mechanisms of the beta-glucan components are presented herein in detail.

Abstract
Agaricus brasiliensis is a well-known medicinal mushroom. We have previously demonstrated that Agaricus-derived polysaccharides exhibit potent antitumor effects; however, the underlying mechanism(s) have not been elucidated yet. In this study, we examined the immunoenhancing activities of Agaricus extracts. Agaricus-derived polysaccharides were characterized as 1,6-β-glucan with a small amount of 1,3-β-glucan using anti-β-glucan antibody and nuclear magnetic resonance analysis. These polysaccharides strongly induced the production of various cytokines from both murine splenocytes and bone marrow-derived dendritic cells in the presence of exogenous granulocyte-macrophage colony-stimulating factor. Polysaccharide-induced cytokine production was significantly reduced in bone marrow-derived dendritic cells derived from dectin-1-deficient mice. Furthermore, a binding assay revealed that the Agaricus-derived polysaccharides can be recognized by dectin-1, a pivotal receptor for 1,3-β-glucan. Taken together, our results clearly indicate that the immunostimulation induced by Agaricus-derived polysaccharides is exerted, at least in part, via dectin-1 in combination with granulocyte-macrophage colony-stimulating factor.

Effects of purified Saccharomyces cerevisiae (1→3)-β-glucan on venous ulcer healing. Int J Mol Sci 2012; 13:8142-8158.

Abstract
Water-insoluble glucan was isolated from the baker’s yeast Saccharomyces cerevisiae. The yeast cells were treated with alkali and the residue then with acid. Chemical and NMR (1D and 2D) analyses showed that a linear (1→3)-β-glucan was purified that was not contaminated with other carbohydrates, proteins or phenolic compounds. The effects of the glucan on wound healing were assessed in human venous ulcers by histopathological analysis after 30 days of topical treatment. (1→3)-β-glucan enhanced ulcer healing and increased epithelial hyperplasia, as well as increased inflammatory cells, angiogenesis and fibroblast proliferation. In one patient who had an ulcer that would not heal for over 15 years, glucan treatment caused a 67.8% decrease in the area of the ulcer. This is the first study to investigate the effects of (1→3)-β-glucan on venous ulcer healing in humans; our findings suggest that this glucan is a potential natural biological response modifier in wound healing.

Abstract
Allergic inflammatory disease such as food allergy, asthma and atopic dermatitis are increasing worldwide. In this study, we investigated the effect of water extract of Sparassis crispa (WESC) Fr. (Aphyllophoromycetideae) on mast cell-mediated allergic inflammation and the possible mechanisms of action. WESC inhibited compound 48/80-induced systemic anaphylaxis and serum histamine release in mice. WESC decreased immunoglobulin E (IgE)-mediated passive cutaneous anaphylaxis. Additionally, WESC reduced histamine release and intracellular calcium in human mast cells activated by phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. WESC decreased PMA and A23187-stimulated expression of pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-α, inlerleukin (IL)-6 and IL-1β. The inhibitory effect of WESC on pro-inflammatory cytokines was nuclear factor-κB, extracellular signal-regulated kinase and p38 mitogen-activated protein kinase-dependent. Our results suggest potential therapeutic application of WESC in allergic inflammatory diseases.
