Abstract
Mushrooms have been recognized for their culinary attributes for long and were relished in the most influential civilizations in history. Currently, they are the focus of renewed research because of their therapeutic abilities. Nutritional benefits from mushrooms are in the form of a significant source of essential proteins, dietary non-digestible carbohydrates, unsaturated fats, minerals, as well as various vitamins, which have enhanced its consumption, and also resulted in the development of various processed mushroom products. Mushrooms are also a crucial ingredient in traditional medicine for their healing potential and curative properties. The literature on the nutritional, nutraceutical, and therapeutic potential of mushrooms, and their use as functional foods for the maintenance of health was reviewed, and the available literature indicates the enormous potential of the bioactive compounds present in mushrooms. Future research should be focused on the development of processes to retain the mushroom bioactive components, and valorization of waste generated during processing. Further, the mechanisms of action of mushroom bioactive components should be studied in detail to delineate their diverse roles and functions in the prevention and treatment of several diseases.

Yu Y, Ou-Yang W, Zhang H, Jiang T, Cho WC, Zhu H, Xiao Z, Li S. High-mobility Group Box 1 Facilitates CD4 T Cell Self-aggregation Via Integrin and STAT3 Activation Before Homing. Inflamm Bowel Dis 2020; 26:1188-1198. [PMID: 32130404 DOI: 10.1093/ibd/izaa044] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND High-mobility group box 1 (HMGB1) is one of the delayed pro-inflammatory cytokines produced in the later stages of pathogenesis and plays an important role in the progression of various inflammatory and autoimmune diseases. High-mobility group box 1 is able to stimulate interaction between integrins and cell adhesion molecules to facilitate cell-cell aggregation in "tissue-specific" endothelium; however, whether and how HMGB1 affects the adhesive capability of early acting immune cells in bloodstream remains largely unknown. METHODS Human peripheral blood samples were collected from healthy adult donors. The CD4 T cells were isolated from blood using CD4 T cell isolation kit and identified using flow cytometry and immunofluorescence staining. The effect of HMGB1 on adhesive ability of CD4 T cells was accessed by cell self-aggregation assay and endothelial adhesion assay. The migratory ability of CD4 T cells was evaluated by cell migration assay. Secretion of pro-inflammatory cytokines or chemokine C-X-C motif chemokine 12 (CXCL12) were detected by ELISA. Expression of integrins β1, β7, and α4β7 were determined by flow cytometric analysis. Inhibition of integrins was achieved with anti-integrin antibodies or cyclic peptide inhibitors. Activation of signal transducers and activators of transcription 3 (STAT3) was measured by flow cytometry and fluorescent staining. RESULTS High-mobility group box 1 facilitated CD4 T cell self-aggregation with simultaneous reduction of CD4 T single-cell counts in the bloodstream. The CD4 T cell self-aggregation induced by HMGB1 resulted in upregulation of integrins β1, β7, and α4β7; release of other pro-inflammatory cytokines or chemokine CXCL12; and activation of STAT3 signaling. Intriguingly, pro-inflammatory cytokines induced by HMGB1 could further amplify CD4 T cell self-aggregation. HMGB1 induced CD4 T cell apoptosis via activation of caspase-3/7. Furthermore, HMGB1 promoted migration and adhesion of CD4 T cells to endothelial cells. CONCLUSIONS These results provide proof of concept that HMGB1 promotes CD4 T cell self-aggregation before homing to inflammatory sites and highlight the potential of blocking immune cell self-aggregation in blood as a novel therapeutic approach against the development and progression of HMGB1-related inflammatory diseases.HMGB1 induces CD4 T cell self-aggregation in blood resulting in upregulation of integrins expression and release of pro-inflammatory cytokines/chemokines via activation of STAT3 signaling. This study highlights the potential of preventive and therapeutic intervention on immune cell self-aggregation in the bloodstream.

Abstract
Mushrooms have a long history of uses for their medicinal and nutritional properties. They have been consumed by people for thousands of years. Edible mushrooms are collected in the wild or cultivated worldwide. Recently, mushroom extracts and their secondary metabolites have acquired considerable attention due to their biological effects, which include antioxidant, antimicrobial, anti-cancer, anti-inflammatory, anti-obesity, and immunomodulatory activities. Thus, in addition to phytochemists, nutritionists and consumers are now deeply interested in the phytochemical constituents of mushrooms, which provide beneficial effects to humans in terms of health promotion and reduction of disease-related risks. In recent years, scientific reports on the nutritional, phytochemical and pharmacological properties of mushroom have been overwhelming. However, the bioactive compounds and biological properties of wild edible mushrooms growing in Southeast Asian countries have been rarely described. In this review, the bioactive compounds isolated from 25 selected wild edible mushrooms growing in Southeast Asia have been reviewed, together with their biological activities. Phytoconstituents with antioxidant and antimicrobial activities have been highlighted. Several evidences indicate that mushrooms are good sources for natural antioxidants and antimicrobial agents.

Polyozellin alleviates atopic dermatitis-like inflammatory and pruritic responses in activated keratinocytes and mast cells. Biomed Pharmacother 2019; 122:109743. [PMID: 31918284 DOI: 10.1016/j.biopha.2019.109743] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Revised: 11/25/2019] [Accepted: 11/27/2019] [Indexed: 12/13/2022] Open
Abstract
Polyozellus multiplex is an edible mushroom that offers beneficial pharmacological effects against intestinal inflammation and cancer. Previous studies have demonstrated that polyozellin, a major component of P. multiplex, has therapeutic activities against inflammation, cancer, and oxidative stress-related disorders. This study aimed to determine the pharmacological effects of polyozellin on inflammatory and pruritic responses, the major symptoms of atopic dermatitis (AD), and to define its underlying mechanism of action. Our results showed that polyozellin inhibited the expression of inflammatory cytokines and chemokines through blockade of signal transducer and activator of transcription 1 and nuclear factor-κB in activated keratinocytes, the major cells involved in AD progression. Based on the histological and immunological analyses, oral treatment with polyozellin attenuated the Dermatophagoides farinae extract (DFE)/2,4-dinitrochlorobenzene (DNCB)-induced atopic inflammatory symptoms in the skin. Pruritus is an unpleasant sensation for AD patients that causes scratching behavior and ultimately exacerbates the severity of AD. To find a possible explanation for the anti-pruritic effects of polyozellin, we investigated its effects on mast cells and mast cell-derived histamines. Oral treatment with polyozellin reduced the DFE/DNCB-induced tissue infiltration of mast cells, the serum histamine levels, and the histaminergic scratching behaviors. Additionally, polyozellin decreased the immunoglobulin E-stimulated degranulation of mast cells. Taken together, the findings of this study provide us with novel insights into the potential pharmacological targets of polyozellin for treating AD by inhibiting the inflammatory and pruritic responses.

Synthesis of polyozellin, a prolyl oligopeptidase inhibitor, and its structural revision. Bioorg Med Chem Lett 2018; 28:930-933. [PMID: 29429833 DOI: 10.1016/j.bmcl.2018.01.054] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2017] [Revised: 01/24/2018] [Accepted: 01/26/2018] [Indexed: 11/23/2022]
Abstract
Polyozellin is a p-terphenyl compound which was isolated from Polyozellus multiplex, and exhibits an inhibitory activity against prolyl oligopeptidase (POP). Its structure was assigned as 1 having a p-terphenyl skeleton including a p-substituted dibenzofuran moiety by spectroscopic analyses and chemical means. This paper describes the total syntheses of the proposed structure 1 for polyozellin and its o-isomer 2, revising the structure of polyozellin to the latter. These syntheses involved a double Suzuki-Miyaura coupling using chlorophenylboronic acid as a common key building block, and Cu mediated Ullmann cyclization as key steps. The inhibitory activities of synthetic compounds against POP and cancer cells were also evaluated.

Abstract
The expression of secretory group IIA phospholipase A2 (sPLA2-IIA) is enhanced by development of inflammatory disorders. In this study, sPLA2-IIA expression was induced in the lipopolysaccharide (LPS)-stimulated human umbilical vein endothelial cells and mice to evaluate the effect of polyozellin. Polyozellin, a major constituent of a Korea edible mushroom Polyozellus multiplex, has been known to exhibit the biological activities such as anti-oxidative and anti-inflammatory effects. Polyozellin remarkably suppressed the LPS-mediated protein expression and activity of sPLA2-IIA via inhibition of phosphorylation of cytosolic phospholipase A2 and extracellular signal-regulated kinase 1/2. These results demonstrated that polyozellin might play an important role in the modulation of sPLA2-IIA expression and activity in response to the inflammatory diseases.
