Polysaccharide isolated from Phellinus linteus mycelia exerts anti-inflammatory effects via MAPK and PPAR signaling pathways. Carbohydr Polym 2018; 200:487-497. [PMID: 30177190 DOI: 10.1016/j.carbpol.2018.08.021] [Citation(s) in RCA: 66] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2018] [Revised: 07/18/2018] [Accepted: 08/06/2018] [Indexed: 12/30/2022]
Abstract
In the present study, the anti-inflammatory function of Phellinus linteus polysaccharide (PLP) was investigated in animal and cell inflammation models, and the anti-inflammatory mechanism of PLP was also explored. Sixty 8-week ICR mice were randomly divided into 3 groups, and DSS group and DSS + PLP group mice received 2.0% DSS and PLP was orally administered at 500 mg/kg/day. Our data showed that PLP administration obviously improved the health status of mice and inhibited DSS-induced pathological alterations and significantly reduced inflammatory cytokine expressions in the colonic tissues. In lipopolysaccharide-induced inflammation cell model, PLP supplement also significantly reduced inflammatory cytokine expressions and inhibited MAPK pathway as well as the translocations of NF-κB and AP-1. Meanwhile, PLP supplement regulated PPARα and PPARγ phosphorylation and blocked MAPK activation. Taken together, PLP exhibits anti-inflammatory function and its molecular mechanism may be involved in MAPK and PPAR signal pathways, which reduce the expressions of inflammatory cytokines.

Abstract
Two novel polysaccharides termed PLPS-1 and PLPS-2 were isolated from mycelia of cultured Phellinus linteus by hot water extraction, purified by DEAE-52 cellulose and Sephadex G-100 column chromatography, and structurally characterized by FTIR and NMR spectroscopy, GC-MS, periodate oxidation/Smith degradation, and methylation analysis. The monosaccharide compositions of PLPS-1 (MW 2.5×10(5)Da) and PLPS-2 (MW 2.8×10(4)Da) were respectively Glc, Ara, Fuc, Gal, and Xyl in molar ratio 21.964:1.336:1.182:1:1, and Glc, Gal, Man, Ara, Fuc, Xyl in molar ratio 14.368:2.594:1.956:1.552:1.466:1; i.e., both were heteropolysaccharides. The backbone of PLPS-1 consisted primarily of repeating α-d-Glc(1→4)-α-d-Glc(1→6) units, while that of PLPS-2 consisted of α-(1→3)-d-Glc and α-(1→6)-d-Glc. The side branches were also different in their carbohydrate components. In in vitro antitumor assays, PLPS-1 displayed strong anti-proliferative effect against S-180 sarcoma cells through apoptosis, whereas PLPS-2 had no such effect. The difference in antitumor activity between the two PLPS evidently results from their structural differences. PLPS-1 has potential as a novel anticancer agent.

Abstract
Phellinus linteus and its constituent hispolon induce potent anti-inflammatory activity in macrophages. Efficient production of the effective constituent and the biological function of P. linteus in the regulation of innate sensing have rarely been investigated. The aim of this study was to efficiently manufacture P. linteus-fermented broth containing the effective constituent, hispolon, and evaluate its immunoregulatory functions in macrophages. Four distinct fermented broths (PL1-4) and the medium dialyzate (MD) were prepared to screen suitable culture conditions for the mycelial growth of P. linteus. The P. linteus-fermented broth exhibited a dose-responsive inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) production by murine macrophages. In addition, the P. linteus-fermented broths suppressed macrophage LPS-mediated nuclear factor (NF)-κB activity and tumor necrosis factor (TNF)-α. Among the tested samples from P. linteus, PL4 contained vast amounts of hispolon and showed the greatest anti-inflammatory activity in both the RAW264.7 cells and murine primary peritoneal exudate macrophages (PEMs). This study demonstrates that the purification of the effective constituent from P. linteus-fermented broth may enable the production of a potent therapeutic agent for anti-inflammation in macrophages.

Protective effect of Phellinus linteus polysaccharide extracts against thioacetamide-induced liver fibrosis in rats: a proteomics analysis. Chin Med 2012; 7:23. [PMID: 23075396 PMCID: PMC3536605 DOI: 10.1186/1749-8546-7-23] [Citation(s) in RCA: 41] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2012] [Accepted: 10/09/2012] [Indexed: 01/10/2023] Open
Abstract
Background The hepatoprotective potential of Phellinus linteus polysaccharide (PLP) extracts has been described. However, the molecular mechanism of PLP for the inhibition of liver fibrosis is unclear. This study aims to investigate the molecular protein signatures involved in the hepatoprotective mechanisms of PLP via a proteomics approach using a thioacetamide (TAA)-induced liver fibrosis rat model. Methods Male Sprague–Dawley rats were divided into three groups of six as follows: Normal group; TAA group, in which rats received TAA only; and PLP group, in which rats received PLP and TAA. Liver fibrosis was induced in the rats by repeated intraperitoneal injections of TAA at a dose of 200 mg/kg body weight twice a week for 4 weeks. PLP was given orally at a dose of 50 mg/kg body weight twice a day from the beginning of the TAA treatment until the end of the experiment. The development of liver cirrhosis was verified by histological examination. Liver proteomes were established by two-dimensional gel electrophoresis. Proteins with significantly altered expression levels were identified by matrix-assisted laser desorption/ionization-time of flight/time of flight mass spectrometry and the differentially expressed proteins were validated by immunohistochemical staining and reverse transcription polymerase chain reaction. Results Histological staining showed a remarkable reduction in liver fibrosis in the rats with PLP treatment. A total of 13 differentially expressed proteins including actin, tubulin alpha-1C chain, preprohaptoglobin, hemopexin, galectin-5, glutathione S-transferase alpha-4 (GSTA4), branched chain keto acid dehydrogenase hterotetrameric E1 subunit alpha (BCKDHA), glutathione S-transferase mu (GSTmu); glyceraldehyde-3-phosphate dehydrogenase (GAPDH); thiosulfate sulfurtransferase (TFT); betaine-homocysteine S-methyltransferase 1 (BHMT1); quinoid dihydropteridine reductase (QDPR); ribonuclease UK114 were observed between the TAA and PLP groups. These proteins are involved in oxidative stress, heme and iron metabolism, cysteine metabolism, and branched-chain amino acid catabolism. Conclusion The proteomics data indicate that P. linteus may be protective against TAA-induced liver fibrosis via regulation of oxidative stress pathways, heat shock pathways, and metabolic pathways for amino acids and nucleic acids.

Abstract
A water-soluble polysaccharide (BIWS-4b) was purified from the fruit bodies of Bulgaria inquinans (Fries). It is composed of mannose (27.2%), glucose (15.5%) and galactose (57.3%). Its molecular weight was estimated to be 7.4 kDa (polydispersity index, Mw/Mn: 1.35). Structural analyses indicated that BIWS-4b mainly contains (1 → 6)-linked, (1 → 5)-linked and (1 → 5,6)-linked β-Galf units; (1 → 4)-linked and non-reducing terminal β-Glcp units; and (1 → 2)-linked, (1 → 6)-linked, (1 → 2,6)-linked and non-reducing terminal α-Manp units. When examined by the 4-day method and in a prophylactic assay in mice, BIWS-4b exhibited markedly suppressive activity against malaria while enhancing the activity of artesunate. Immunological tests indicated that BIWS-4b significantly enhanced macrophage phagocytosis and splenic lymphocyte proliferation in malaria-bearing mice and normal mice. The anti-malarial activity of BIWS-4b might be intermediated by enhancing immune competence and restoring artesunate-suppressed immune function. Thus, BIWS-4b is a potential adjuvant of anti-malaria drugs.

Abstract
BACKGROUND A large body of literature suggests that certain polysaccharides affect immune system function. Much of this literature, however, consists of in vitro studies or studies in which polysaccharides were injected. Their immunologic effects following oral administration is less clear. The purpose of this systematic review was to consolidate and evaluate the available data regarding the specific immunologic effects of dietary polysaccharides. METHODS Studies were identified by conducting PubMed and Google Scholar electronic searches and through reviews of polysaccharide article bibliographies. Only articles published in English were included in this review. Two researchers reviewed data on study design, control, sample size, results, and nature of outcome measures. Subsequent searches were conducted to gather information about polysaccharide safety, structure and composition, and disposition. RESULTS We found 62 publications reporting statistically significant effects of orally ingested glucans, pectins, heteroglycans, glucomannans, fucoidans, galactomannans, arabinogalactans and mixed polysaccharide products in rodents. Fifteen controlled human studies reported that oral glucans, arabinogalactans, heteroglycans, and fucoidans exerted significant effects. Although some studies investigated anti-inflammatory effects, most studies investigated the ability of oral polysaccharides to stimulate the immune system. These studies, as well as safety and toxicity studies, suggest that these polysaccharide products appear to be largely well-tolerated. CONCLUSIONS Taken as a whole, the oral polysaccharide literature is highly heterogenous and is not sufficient to support broad product structure/function generalizations. Numerous dietary polysaccharides, particularly glucans, appear to elicit diverse immunomodulatory effects in numerous animal tissues, including the blood, GI tract and spleen. Glucan extracts from the Trametes versicolor mushroom improved survival and immune function in human RCTs of cancer patients; glucans, arabinogalactans and fucoidans elicited immunomodulatory effects in controlled studies of healthy adults and patients with canker sores and seasonal allergies. This review provides a foundation that can serve to guide future research on immune modulation by well-characterized polysaccharide compounds.

Abstract
BACKGROUND Congaplex and Immuplex are dietary supplements that have been traditionally used to support immune system function. The purpose of these experiments was to determine whether Congaplex and Immuplex affect immune function using primary and immortalized T lymphocytes. METHODS Immortalized CEM and Jurkat T lymphocytes and primary peripheral mononuclear blood cells (PBMCs) were treated with the aqueous extracts from Congaplex and Immuplex to determine the effects of these products on cytokine production in activated T lymphocytes. RESULTS Congaplex enhanced phytohemagglutinin/phorbol 12-myristate 13-acetate (PHA/PMA) stimulation of both CEM and Jurkat cells as measured by the production of cytokines, while Immuplex suppressed PHA/PMA-induced production of cytokines, with the exception of interleukin (IL)-8 which was enhanced by Immuplex. In vitro treatment of PBMCs from 10 healthy donors with Congaplex or Immuplex decreased PHA-stimulated production of interferon (IFN)-gamma but increased the production of IL-13. CONCLUSIONS While the effects of Congaplex and Immuplex differed in these two models, these data demonstrate that the aqueous extracts from these two dietary supplements can affect the inflammatory response of T lymphocytes.
