Unveiling the potential mechanisms of Amomi fructus against gastric ulcers via integrating network pharmacology and in vivo experiments. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117179. [PMID: 37777029 DOI: 10.1016/j.jep.2023.117179] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 09/04/2023] [Accepted: 09/11/2023] [Indexed: 10/02/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a well-known traditional Chinese medicine, Amomi fructus (A. fructus) (Sharen) has been used therapeutically to treat gastrointestinal illnesses, including gastric ulcer (GU). The mechanism underlying this impact is still not fully known, though. AIM OF THE STUDY To investigate the hidden mechanism by which A. fructus influences the pathogenesis of GU, we employed network pharmacology approaches and in vivo validated studies. MATERIALS AND METHODS Multiple public databases were used to compile information on bioactive compounds, potential targets of A. fructus, and associated genes of GU. Then, the STRING database's protein-protein interaction (PPI) data of the drug-disease overlapping gene targets was obtained, and the core targets for A. fructus against GU were discovered. Additionally, molecular docking was done to examine the binding capabilities of the active substances and core targets. Then, the pathways of A. fructus that target GU were examined using the Annotation, Visualization and Integrated Discovery (DAVID)'s Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway studies. In a mouse model of acute stomach mucosal damage brought on by absolute ethanol, the findings of network pharmacology were finally validated. RESULTS In total, 610 targets derived from the 196 bioactive compounds in A. fructus, were discovered, and along with 115 A. fructus target genes for therapy of GU. Then, ten core targets associated with apoptosis and inflammation were determined based on node degree, and ALB, AKT1, TNF, EGFR, MAPK3, CASP3, MMP9, STAT3, SRC, and HRAS were identified as promising therapeutic targets of A. fructus against GU. The results of molecular docking also revealed that 65 active compounds had strong binding activity with the core targets, with volatile chemicals being the most significant active ingredients. So, for following in vivo tests, A. fructus volatile oils (AVO) were used. The KEGG analysis showed that the phosphoinositide-3-kinase/protein kinase B (PI3K/AKT) signaling pathway may be crucial for the therapeutic mechanism of GU. In experiments that were validated in vivo, AVO considerably decreased the ulcer area and enhanced the histological appearance of the gastric tissues. In addition, compared to the model group, up-regulated the expression of IGF-1, p-PI3K, and p-AKT and down-regulated the protein levels of TNF-α and Caspase 3 in the stomach tissues. CONCLUSION According to preliminary findings from this work, A. fructus may influence inflammatory response and apoptosis via regulating the PI3K/AKT signaling pathway and associated gene targets. Importantly, our research might offer a theoretical foundation for future research into the intricate anti-GU mechanism of A. fructus.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Amomum belonging to the family Zingiberaceae, is mainly distributed in tropical regions of Asia and Oceania. Their fruits and seeds are valuable traditional medicine and used extensively, particularly in South China, India, Malaysia, and Vietnam. The genus Amomum has long been used for treating gastric diseases, digestive disorder, cancer, hepatopathy, malaria, etc. AIMS OF THE REVIEW: The main purpose of this review is to provide the available information on the traditional medicinal uses, phytochemistry, and pharmacology aspects of the genus Amomum in order to explore the trends and perspectives for further studies on its non-volatile constituents. MATERIALS AND METHODS The present review collected the literatures published prior to 2020 on the traditional medicinal uses, phytochemistry, and pharmacology of the genus Amomum. The available literatures were extracted from scientific databases, such as Sci-finder, PubMed, Web of Science, Google Scholar, Baidu Scholar, and CNKI, books, and others. RESULTS Herein, we summarize all 166 naturally occurring non-volatile compounds from 16 plants of the genus Amomum reported in 171 references, including flavonoids, terpenoids, diarylheptanoids, coumarins, etc. Triterpenes and flavonoids are the main constituents among these compounds and maybe play an important role in the activities directly or indirectly. As traditional medicine, the plants from the genus Amomum have been usually used in some traditional herbal prescriptions, and pharmacological researches in vitro and in vivo revealed that the extracts possessed significant antioxidant, anti-inflammatory, anti-allergic activities, etc. CONCLUSION: The review systematically summarizes current studies on traditional medicinal uses, phytochemistry, pharmacological activity on the plants from the genus Amomum. To date, the majority of publications still focused on the research of volatile constituents. However, the promising preliminary data of non-volatile constituents indicated the research potential of this genus in phytochemical and pharmacological aspects. Furthermore, the further in-depth investigations on the safety, efficacy, as well as the stereo-chemistry and structure-activity relationships of pure compounds from this genus are essential in the future.

Abstract
Allergic rhinitis (AR) is a common inflammatory condition of the nasal mucosa and it is an immunoglobulin E-mediated disease. The incidence and prevalence of AR globally have been escalating over recent years. Antihistamines, intranasal corticosteroids, decongestants, intranasal anticholinergics, intranasal cromolyn, leukotriene receptor antagonists and immunotherapy have been used in the treatment of AR. However, there is a need to search for more effective and safer remedies as many of the current treatments have reported side effects. Medicinal plants have been used traditionally to relief symptoms of AR but their efficacy and safety have not been scientifically proven. In this review, up-to-date reports of studies on the anti-allergic rhinitis of several medicinal plants and their bioactive metabolites through suppression of the immune system are compiled and critically analyzed. The plant samples were reported to suppress the productions of immunoglobulin E, cytokines and eosinophils and inhibit histamine release. The suppression of cytokines production was found to be the main mechanistic effect of the plants to give symptomatic relief. The prospect of these medicinal plants as sources of lead molecules for development of therapeutic agents to treat AR is highlighted. Several bioactive metabolites of the plants including shikonin, okicamelliaside, warifteine, methylwarifteine, luteolin-7-O-rutinoside, tussilagone, petasin, and mangiferin have been identified as potential candidates for development into anti-allergic rhinitis agents. The data collection was mainly from English language articles published in journals, or studies from EBSCOHOST, Medline and Ovid, Scopus, Springer, and Google Scholar databases from the year 1985-2020. The terms or keywords used to find relevant studies were allergic rhinitis OR pollinosis OR hay fever, AND medicinal plant OR single plant OR single herb OR phytotherapy. This comprehensive review serves as a useful resource for medicinal plants with anti-allergic rhinitis potential, understanding the underlying mechanisms of action and for future exploration to find natural product candidates in the development of novel anti-allergic rhinitis agents.

[PMID: 32899766 PMCID: PMC7570676 DOI: 10.3390/molecules25184051] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 09/02/2020] [Accepted: 09/02/2020] [Indexed: 12/17/2022] Open
Abstract
Allergic rhinitis and asthma are common chronic allergic diseases of the respiratory tract, which are accompanied by immunoglobulin E (IgE)-mediated inflammation and the involvement of type 2 T helper cells, mast cells, and eosinophils. Cordyceps sinensis (Berk.) Sacc is a fungal parasite on the larva of Lepidoptera. It has been considered to be a health-promoting food and, also, one of the best-known herbal remedies for the treatment of airway diseases, such as asthma and lung inflammation. In the present study, we demonstrated the antiallergic rhinitis effect of Cs-4, a water extract prepared from the mycelium culture of Cordyceps sinensis (Berk) Sacc, on ovalbumin (OVA)-induced allergic rhinitis in mice and the anti-asthmatic effect of Cs-4 in a rat model of asthma. Treatment with Cs-4 suppressed the nasal symptoms induced in OVA-sensitized and challenged mice. The inhibition was associated with a reduction in IgE/OVA-IgE and interleukin (IL)-4/IL-13 levels in the nasal fluid. Cs-4 treatment also decreased airway responsiveness and ameliorated the scratching behavior in capsaicin-challenged rats. It also reduced plasma IgE levels, as well as IgE and eosinophil peroxidase levels, in the bronchoalveolar fluid. Cs-4 treatment completely suppressed the increases in IL-4, IL-5, and IL-13 levels in rat lung tissue. In conclusion, our results suggest that Cs-4 has the potential to alleviate immune hypersensitivity reactions in allergic rhinitis and asthma.

Abstract
Chemical composition, in vitro antioxidant, DNA damage protective, nitrite scavenging activities, as well as antibacterial activity of Amomum kravanh fruits essential oil against several foodborne pathogens, were investigated. Results showed that the 1,8-cineole (58.53%) was found as the main component, followed by α-pinene (8.32%), α-terpinyl acetate (4.68%), α-terpinolene (4.12%), α-terpinene (3.55%), β-pinene (3.49%). The essential oil had significant antioxidant activity, the protective effect against DNA damage, and nitrite scavenging activity. These biological activities were dose-dependent, increasing with the higher dosage in a certain concentration range. The essential oil exhibited antibacterial activity against four foodborne pathogens with the minimum inhibitory concentration (MIC) of 5-10 mg/mL and minimum bactericide concentration (MBC) of 10-20 mg/mL. The antibacterial effects of essential oil were greater against Gram-positive bacteria as compared to Gram-negative bacteria. These results suggested that essential oil could be available as a significant natural agent for prevention of food oxidation and spoilage.

Abstract
Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disorder. The present study investigated the effects of Amomum xanthioides extract (AXE) on AD‑like skin inflammation using a Dermatophagoides farinae extract (DFE) and 2,4‑dinitrochlorobenzene (DNCB)‑induced mouse AD model. Hematoxylin and eosin staining results demonstrated that repeated DFE/DNCB exposure markedly increased the thickening of the dermis and epidermis, in addition to the infiltration of eosinophils and mast cells. However, oral administration of AXE reduced these histopathological alterations in a dose‑dependent manner. Elevated serum histamine, total and DFE‑specific immunoglobulin E (IgE), and IgG2a were also decreased by treatment with AXE. In addition, reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) results demonstrated that the mRNA expression of tumor necrosis factor (TNF)‑α, interferon (IFN)‑γ, interleukin (IL)‑4, IL‑13, IL‑31 and IL‑17A was reduced in ear skin following AXE administration in AD mice. Fluorescence‑activated cell sorting demonstrated that the population of CD4+/IL‑4+, CD4+/IFN‑γ+ and CD4+/IL‑17A+ cells in draining lymph nodes was also significantly decreased in AXE‑treated mice compared with AD mice without AXE treatment. Furthermore, keratinocytes that were stimulated with TNF‑α and IFN‑γ exhibited increased gene expression of pro‑inflammatory cytokines and chemokines, including TNF‑α, IL‑1β, IL‑6, IL‑8, C‑C motif chemokine ligand (CCL)17 and CCL22, as determined by RT‑qPCR. However, upregulation of these genes was reduced by AXE pretreatment. Based on these results, we hypothesize that AXE may be useful in the treatment of allergic skin inflammation, particularly AD.

Abstract
Mast cells (MCs) are key effector cells of IgE-FcεRI- or MrgprX2-mediated signaling event. Shuang-Huang-Lian (SHL), a herbal formula from Chinese Pharmacopoeia, has been clinically used in type I hypersensitivity. Our previous study demonstrated that SHL exerted a non-negligible effect on MC stabilization. Herein, we sought to elucidate the molecular mechanisms of the prominent anti-allergic ability of SHL. MrgprX2- and IgE-FcεRI-mediated MC activation in vitro and in vivo models were developed by using compound 48/80 (C48/80) and shrimp tropomyosin (ST), respectively. Our data showed that SHL markedly dampened C48/80- or ST-induced MC degranulation in vitro and in vivo. Mechanistic study indicated that cytosolic Ca2+ (Ca2+[c]) level decreased rapidly and sustainably after SHL treatment, and then returned to homeostasis when SHL was withdrawn. Moreover, SHL decreases Ca2+[c] levels mainly through enhancing the mitochondrial Ca2+ (Ca2+[m]) uptake. After genetically silencing or pharmacologic inhibiting mitochondrial calcium uniporter (MCU), the effect of SHL on the Ca2+[c] level and MC degranulation was significantly weakened. Simultaneously, the activation of SHL on Ca2+[m] uptake was completely lost. Collectively, by activating MCU, SHL decreases Ca2+[c] level to stabilize MCs, thus exerting a remarkable anti-allergic activity, which could have considerable influences on clinical practice and research.

Abstract
Mast cells are important effector cells in immunoglobulin (Ig) E-mediated allergic reactions such as asthma, atopic dermatitis and rhinitis. Vanillic acid, a natural product, has shown anti-oxidant and anti-inflammatory activities. In the present study, we investigated the anti-allergic inflammatory effects of ortho-vanillic acid (2-hydroxy-3-methoxybenzoic acid, o-VA) that was a derivative of vanillic acid isolated from Amomum xanthioides. In mouse anaphylaxis models, oral administration of o-VA (2, 10, 50 mg/kg) dose-dependently attenuated ovalbumin-induced active systemic anaphylaxis and IgE-mediated cutaneous allergic reactions such as hypothermia, histamine release, IgE production and vasodilation; administration of o-VA also suppressed the mast cell degranulator compound 48/80-induced anaphylaxis. In cultured mast cell line RBL-2H3 and isolated rat peritoneal mast cells in vitro, pretreatment with o-VA (1-100 μmol/L) dose-dependently inhibited DNP-HSA-induced degranulation of mast cells by decreasing the intracellular free calcium level, and suppressed the expression of pro-inflammatory cytokines TNF-α and IL-4. Pretreatment of RBL-2H3 cells with o-VA suppressed DNP-HSA-induced phosphorylation of Lyn, Syk, Akt, and the nuclear translocation of nuclear factor-κB. In conclusion, o-VA suppresses the mast cell-mediated allergic inflammatory response by blocking the signaling pathways downstream of high affinity IgE receptor (FcεRI) on the surface of mast cells.

Abstract
BACKGROUND Mast cells are a critical component of allergic responses in humans, and animal models that allow the in vivo investigation of their contribution to allergy and evaluation of new human-specific therapeutics are urgently needed. OBJECTIVE To develop a new humanized mouse model that supports human mast cell engraftment and human IgE-dependent allergic responses. METHODS This model is based on the NOD-scid IL2rg(null)SCF/GM-CSF/IL3 (NSG-SGM3) strain of mice engrafted with human thymus, liver, and hematopoietic stem cells (termed Bone marrow, Liver, Thymus [BLT]). RESULTS Large numbers of human mast cells develop in NSG-SGM3 BLT mice and populate the immune system, peritoneal cavity, and peripheral tissues. The human mast cells in NSG-SGM3 BLT mice are phenotypically similar to primary human mast cells and express CD117, tryptase, and FcεRI. These mast cells undergo degranulation in an IgE-dependent and -independent manner, and can be readily cultured in vitro for additional studies. Intradermal priming of engrafted NSG-SGM3 mice with a chimeric IgE containing human constant regions resulted in the development of a robust passive cutaneous anaphylaxis response. Moreover, we describe the first report of a human mast cell antigen-dependent passive systemic anaphylaxis response in primed mice. CONCLUSIONS NSG-SGM3 BLT mice provide a readily available source of human mast cells for investigation of mast cell biology and a preclinical model of passive cutaneous anaphylaxis and passive systemic anaphylaxis that can be used to investigate the pathogenesis of human allergic responses and to test new therapeutics before their advancement to the clinic.

Abstract
Mast cells play a critical role in type 1 hypersensitivity reactions. Indeed, mast cell mediators are implicated in many different conditions including allergic rhinitis, conjunctivitis, asthma, psoriasis, mastocytosis and the progression of many different cancers. Thus, there is intense interest in the development of agents which prevent mast cell mediator release or which inhibit the actions of such mediators once released into the environment of the cell. Much progress into the design of new agents has been made since the initial discovery of the mast cell stabilising properties of khellin from Ammi visnaga and the clinical approval of cromolyn sodium. This review critically examines the progress that has been made in the intervening years from the design of new agents that target a specific signalling event in the mast cell degranulation pathway to those agents which have been developed where the precise mechanism of action remains elusive. Particular emphasis is also placed on clinically used drugs for other indications that stabilise mast cells and how this additional action may be harnessed for their clinical use in disease processes where mast cells are implicated.

Abstract
As the importance of allergic disorders such as atopic dermatitis and allergic asthma, research on potential drug candidates becomes more necessary. Mast cells play an important role as initiators of allergic responses through the release of histamine; therefore, they should be the target of pharmaceutical development for the management of allergic inflammation. In our previous study, anti-allergic effect of extracts of Amomum xanthioides was demonstrated. To further investigate improved candidates, 1,2,4,5-tetramethoxybenzene (TMB) was isolated from methanol extracts of A. xanthioides. TMB dose-dependently attenuated the degranulation of mast cells without cytotoxicity by inhibiting calcium influx. TMB decreased the expression of pro-inflammatory cytokines such as tumor necrosis factor-α and interleukin (IL)-4 at both the transcriptional and translational levels. Increased expression of these cytokines was caused by translocation of nuclear factor-κB into the nucleus, and it was hindered by suppressing activation of IκB kinase complex. To confirm the effect of TMB in vivo, the ovalbumin (OVA)-induced active systemic anaphylaxis (ASA) and IgE-mediated passive cutaneous anaphylaxis (PCA) models were used. In the ASA model, hypothermia was decreased by oral administration of TMB, which attenuated serum histamine, OVA-specific IgE, and IL-4 levels. Increased pigmentation of Evans blue was reduced by TMB in a dose-dependent manner in the PCA model. Our results suggest that TMB is a possible therapeutic candidate for allergic inflammatory diseases that acts through the inhibition of mast cell degranulation and expression of pro-inflammatory cytokines.

Abstract
Mast cell stabilizing drugs inhibit the release of allergic mediators from mast cells and are used clinically to prevent allergic reactions to common allergens. Despite the relative success of the most commonly prescribed mast cell stabilizer, disodium cromoglycate, in use for the preventative treatment of bronchial asthma, allergic conjunctivitis and vernal keratoconjunctivitis, there still remains an urgent need to design new substances that are less expensive and require less frequent dosing schedules. In this regard, recent developments towards the discovery of the next generation of mast cell stabilizing drugs has included studies on substances isolated from natural sources, biological, newly synthesized compounds and drugs licensed for other indications. The diversity of natural products evaluated range from simple phenols, alkaloids, terpenes to simple amino acids. While in some cases their precise mode of action remains unknown it has nevertheless sparked interest in the development of synthetic derivatives with improved pharmacological properties. Within the purely synthetic class of inhibitors, particular attention has been devoted to the inhibition of important signalling molecules including spleen TK and JAK3. The statin class of cholesterol-lowering drugs as well as nilotinib, a TK inhibitor, are just some examples of clinically used drugs that have been evaluated for their anti-allergic properties. Here, we examine each approach under investigation, summarize the test data generated and offer suggestions for further preclinical evaluation before their therapeutic potential can be realized.

Abstract
Diospyros kaki (D. kaki) has been cultivated throughout Eastern Asia for hundreds of years. D. kaki contains various biological active compounds, such as amino acids, carotenoids, flavonoids, tannins, catechins and vitamin A. Previous studies have shown that D. kaki has beneficial effects on homeostasis, constipation, hypertension, atherosclerosis and allergic dermatitis and is a good source of antioxidants, polyphenols and dietary fiber. However, the anti-allergic and anti-inflammatory effects of D. kaki have not yet been elucidated. This study aimed to investigate the protective effects of the aqueous extract of Diospyros kaki (AEDK) on mast cell-mediated allergic inflammation and to determine its possible mechanisms of action by using in vitro and in vivo mast cell-based models. The cAMP and intracellular calcium levels were measured to clarify the mechanisms by which AEDK inhibits the release of histamine from mast cells. AEDK inhibited the release of histamine and β-hexosaminidase from mast cells by modulating cAMP and intracellular calcium levels. We also measured the expression of pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-α and interleukin (IL)-1β. AEDK decreased gene expression and the secretion of the pro-inflammatory cytokines, TNF-α and IL-1β by inhibiting nuclear factor-κB. In addition, AEDK inhibited systemic and cutaneous allergic reaction. The inhibitory effects of AEDK on allergic reaction and the release of histamine were found to be similar to those of disodium cromoglycate, a known anti-allergic drug. To isolate the active component of AEDK, activity-guided fractionation was performed, based on the inhibitory effects on systemic anaphylaxis. Catechin was identified as an active compound. The present findings provide evidence that AEDK inhibits allergic inflammation and suggest the therapeutic application of AEDK in allergic inflammatory disorders.

Abstract
The aim of the present study was to elucidate whether extracts of Vigna angularis (EVA) inhibit allergic inflammatory reactions and to elucidate the possible mechanisms of action. For the assessment of allergic inflammatory response, histamine release and the expression of pro-inflammatory cytokines from human mast cells (HMC-1) were examined. To identify the underlying mechanisms of action, intracellular calcium and the activation of nuclear factor (NF)-κB and mitogen-activated protein kinases (MAPKs) were assayed. To confirm the effects of EVA in vivo, systemic and local allergic reaction mouse models were employed. EVA dose-dependently reduced phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-induced histamine release from mast cells. The inhibitory effects of EVA on the release of histamine from mast cells were mediated by the reduction of intracellular calcium levels. EVA decreased the PMACI-stimulated gene expression and secretion of pro-inflammatory cytokines, such as tumor necrosis factor (TNF)-α and interleukin (IL)-6. The inhibitory effects of EVA on pro-inflammatory cytokines were NF-κB- and MAPK-dependent. In addition, EVA inhibited compound 48/80-induced systemic anaphylaxis and immunoglobulin E (IgE)-mediated cutaneous anaphylaxis. Our findings provide evidence that EVA inhibits mast cell-derived allergic inflammation, and suggest the possible therapeutic application of EVA in allergic inflammatory disorders.

Abstract
Allergic inflammatory diseases such as food allergy, asthma, sinusitis, and atopic dermatitis are increasing worldwide. In this study, we investigated the effects of aqueous extract of Mosla chinensis Max. (AMC) on mast cell-mediated allergic inflammation and studied the possible mechanism of this action. AMC inhibited compound 48/80-induced systemic and immunoglobulin E (IgE)-mediated local anaphylaxis. AMC reduced intracellular calcium levels and downstream histamine release from rat peritoneal mast cells activated by compound 48/80 or IgE. In addition, AMC decreased gene expression and secretion of proinflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-8 in human mast cells. The inhibitory effect of AMC on cytokine expression was nuclear factor (NF)-κB dependent. Our results indicate that AMC inhibits mast cell-mediated allergic inflammatory reaction by suppressing histamine release and expression of proinflammatory cytokines and the involvement of calcium and NF-κB in these effects. AMC might be a possible therapeutic candidate for allergic inflammatory disorders.

Abstract
Piceatannol is a phenolic stilbenoid and a metabolite of resveratrol which is found in red wine. Piceatannol (PIC) commonly exhibits anti-inflammatory, antiplatelet and antiproliferative activity. In the present study, the anti-allergic and anti-inflammatory mechanisms of PIC were investigated by examining the effects of PIC on pro‑inflammatory cytokine release and phosphorylation of mitogen-activated protein (MAP) kinases (ERK, JNK and p38) in a human mast cell line. PIC dose-dependently inhibited compound 48/80-induced systemic anaphylaxis and immunoglobulin E-mediated local allergic reactions. PIC reduced the immunoglobulin E (IgE)-mediated local allergic reaction and attenuated histamine release from rat peritoneal mast cells. Histamine and β-hexosaminidase release was markedly decreased dose-dependently by PIC treatment in RBL-2H3 cells. PIC treatments of HMC-1 cells definitely reduced mRNA expression and the release of the pro‑inflammatory cytokines, tumor necrosis factor-α and interleukin-8. MAP kinase phosphorylation was also strongly decreased dose-dependently following PIC treatment. PIC regulated the production of cytokines and histamine in phorbol 12-myristate 13-acetate plus A23187-stimulated mast cells. Thus, PIC may alleviate allergic inflammation and may be a useful therapeutic agent for allergic diseases.

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.

Toxicol Lett 2012; 210:64-70. [PMID: 22322153 DOI: 10.1016/j.toxlet.2012.01.014] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2011] [Revised: 01/18/2012] [Accepted: 01/19/2012] [Indexed: 10/14/2022]
Abstract
Perfluorooctanoic acid (PFOA) has unique physical and chemical characteristics, water and oil repellency, thermal stability, and surfactant properties. PFOA has been regularly found in the blood of animals and humans worldwide, and has become an increasing concern because of its adverse effects in immune system. However, the role of PFOA in the allergic inflammation is not well-known. To further extend the immunotoxicity of PFOA, we examined the role of PFOA on the mast cell-mediated allergic inflammation and studied the possible mechanism of action. PFOA dose- and time-dependently increased histamine release from mast cells and serum histamine by the induction of intracellular calcium. PFOA exacerbated the IgE-dependent local allergic reaction in the mouse allergy model. PFOA induced gene expression of pro-inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-8 in mast cells. The inducing effect of PFOA on the pro-inflammatory cytokines was nuclear factor-κB, p38 mitogen-activated protein kinase, and caspase-1 dependent. Furthermore, the activation of cyclooxygenase-2 by PFOA suggests the induction of allergic inflammatory mediators by the PFOA. Our findings provide evidence that PFOA, the known immunotoxic agent, induces mast cell-derived allergic inflammatory reactions by histamine release and expression of pro-inflammatory cytokines.

Abstract
Mast cell-mediated allergic reaction is involved in many diseases such as asthma and allergic rhinitis. Therefore, discovery of drugs for the prevention or treatment of allergic disease is an important topic in human health. In this study, we evaluated the effects of water extract of Elsholtzia ciliata (Thunb.) Hyland (Labiatae) (WEEC) on mast cell-mediated allergic inflammation and studied the possible mechanisms of action. WEEC inhibited compound 48/80-induced systemic and immunoglobulin E-mediated local anaphylaxis, and serum histamine release in mice. WEEC reduced intracellular calcium levels and downstream histamine release from human mast cells (HMC-1) activated with phorbol 12-myristate 13-acetate and calcium ionophore A23187. In addition, WEEC decreased gene expression and secretion of proinflammatory cytokines such as tumor necrosis factor-α, interleukin (IL)-1β and IL-6 in HMC-1. The inhibitory effect of WEEC on cytokine expression was nuclear factor (NF)-κB and p38 mitogen-activated protein kinase (MAPK) dependent. Our results indicate that WEEC inhibits mast cell-mediated allergic inflammatory reactions by suppressing histamine release and proinflammatory cytokine expression, and involvement of calcium, NF-κB and p38 MAPK in these effects.

Abstract
A great number of people are suffering from allergic inflammatory diseases such as asthma, atopic dermatitis, and sinusitis. Therefore discovery of drugs for the treatment of these diseases is an important subject in human health. Chrysin (5,7-dihydroxyflavone) is a natural flavonoid contained in propolis, blue passion flower, and fruits. Several studies reported that chrysin has beneficial effects including anti-tumor and anti-oxidant activities. The aim of the present study was to elucidate whether chrysin modulates the allergic inflammatory reaction and to study its possible mechanisms of action using mast cell-based in vitro and in vivo models. Chrysin inhibited immediate-type systemic hypersensitivity and serum histamine release. Chrysin attenuated immunoglobulin E-mediated local anaphylaxis. These inhibitory effects of chrysin on the systemic and local allergic reaction were more potent than cromolyn, a known anti-allergic drug. Chrysin reduced histamine release from mast cells. The inhibitory effect of chrysin on the histamine release was mediated by the modulation of intracellular calcium. In addition, chrysin decreased gene expression of pro-inflammatory cytokines such as, tumor necrosis factor-α, IL (interleukin)-1β, IL-4, and IL-6 in mast cells. The inhibitory effect of chrysin on the pro-inflammatory cytokine was nuclear factor-κB and caspase-1 dependent. Our findings provide evidence that chrysin inhibits mast cell-derived allergic inflammatory reactions by blocking histamine release and pro-inflammatory cytokine expression, and suggest the mechanisms of action. Furthermore, in vivo and in vitro anti-allergic inflammatory effect of chrysin suggests a possible therapeutic application of this agent in allergic inflammatory diseases.

Abstract
Leaves of Eriobotrya japonica Lindl. (Rosaceae) (LEJL) have been used as traditional medicines for inflammatory diseases and chronic bronchitis. However, its effect on mast cell-mediated anaphylactic reaction is not known. The anaphylactic allergic reaction is involved in many allergic diseases such as asthma and allergic rhinitis. In this report, we investigate the effect of LEJL on the anaphylactic allergic reaction and studied its possible mechanisms of action. LEJL inhibited compound 48/80-induced systemic anaphylactic reactions and serum histamine release in mice. LEJL dose-dependently decreased the IgE-mediated passive cutaneous anaphylaxis and histamine release from mast cells. Furthermore, LEJL decreased the production of tumor necrosis factor-alpha in phorbol 12-myristate 13-acetate and A23187-stimulated human mast cells. These findings provide evidence that LEJL could be a candidate as an anti-allergic agent.

Abstract
Chlorogenic acid (CGA), a naturally occurring polyphenol compound, has a number of biological activities. However, roles of CGA in the mast cell-dependent anaphylactic reaction have not been fully examined. In the present study, the effect and mechanism of CGA on mast cell-dependent anaphylactic reaction were investigated using in vivo and in vitro models. CGA inhibited compound 48/80-induced systemic anaphylactic shock in mice and skin vascular permeability in rats. CGA also inhibited anti-dinitrophenyl (DNP) IgE-mediated passive cutaneous anaphylaxis (PCA). Moreover, CGA dose-dependently reduced histamine and TNF-alpha release from RBL-2H3 cells activated by anti-DNP IgE. Pretreatment with CGA suppressed IgE-antigen complex induced calcium uptake into RBL-2H3 cells. When CGA was added, the level of intracellular cyclic adenosine monophosphate (cAMP) in RBL-2H3 cells was significantly elevated compared with the untreated cells. Decreased calcium uptake and increased cAMP level might be involved in the inhibitory effect of CGA on mast cell activation. These results suggest a possible therapeutic application of CGA in allergic diseases.

Abstract
The present study was performed to investigate the anti-allergy potentials of glycoprotein (90kDa) isolated from Opuntia ficus-indica var. saboten MAKINO (OFI glycoprotein) in vivo (ICR mice) and in vitro (RBL-2H3 cells). At first, to know whether the OFI glycoprotein has an inhibitory ability for allergy in vivo, we evaluated the activities of allergy-related factors such as histamine and beta-hexosaminidase release, lactate dehydrogenase (LDH), and interleukin 4 (IL-4) in compound 48/80 (8 ml/kg BW)-treated ICR mice. After that, we studied to found the effect for anti-allergy in vitro such as nuclear factor kappa B (NF-kappaB) and inducible nitric oxide synthase (iNOS), extracellular signal-regulated kinase (ERK) 1/2, arachidonic acid, and cyclooxygenase-2 (COX-2) in compound 48/80 (5 microg/ml)-treated RBL-2H3 cells. Our results showed that the OFI glycoprotein (5 mg/kg) inhibited histamine and beta-hexosaminidase release, lactate dehydrogenase (LDH), and interleukin 4 (IL-4) in mice serum. Also OFI glycoprotein (25 microg/ml) has suppressive effects on the expression of MAPK (ERK1/2), and on protein expression of anti-allergic proteins (iNOS and COX-2). Thus, we speculate that the OFI glycoprotein is an example of natural compound that blocks anti-allergic signal transduction pathways.

Abstract
Mast cell-mediated allergic inflammation is involved in many diseases such as asthma and sinusitis. Mast cells induce synthesis and production of pro-inflammatory cytokines including tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and IL-8 with immune regulatory properties. In the present study, we investigate the effect an unspecified aqueous extract from leaves of Eriobotrya japonica Lindl. (Rosaceae) (LEJL) on the expression of pro-inflammatory cytokines and its possible mechanisms of action in human mast cells (HMC-1). LEJL dose-dependently inhibited phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187 (PMACI)-induced gene expression and secretion of TNF-alpha, IL-6, and IL-8. LEJL attenuated PMACI-induced activation of nuclear factor (NF)-kappaB, and specifically blocked activation of p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase (ERK) but not that of c-jun N-terminal kinase. The inhibitory effect of LEJL on the pro-inflammatory cytokines was likely NF-kappaB, p38 MAPK, and ERK dependent. Our in vitro studies provide evidence that LEJL might contribute to the treatment of mast cell-derived allergic inflammatory diseases.

Abstract
Even in the 21st century, some seeds of tradition remain firmly grounded regardless of the technological advancements of humankind. One such "tradition" involves using unconventional means-including mental healing, herbal formulas, and healing hand therapies such as acupuncture-to treat chronic illnesses. Although mental healing is unproven and energy therapy is not completely understood, acupuncture, herbal therapy, and sublingual immunotherapy have been described more extensively with mixed results that lack consistency and high-quality scientific data. Researchers are working to modernize these traditional therapies in the treatment of allergic disorders and using advanced technology to alter what some call "the earth's natural healing power" in hopes of developing a new, integrative form of medicine.

Abstract
Complementary and alternative medicines (CAMs) are used in more than 80% of the world's population and are becoming an increasing component of the US health care system, with more than 70% of the population using CAM at least once and annual spending reaching as much as $34 billion. Since the inception of the National Center for Complementary and Alternative Medicine, there has been an enormous increase in the number of basic science and therapy-based clinical trials exploring CAM. The subspecialty of allergy and immunology represents a particularly fertile area with a large number of CAM therapies that have been shown to affect the immune system. Recent work has uncovered potential biochemical mechanisms involved in the immunomodulatory pathway of many supplemental vitamins (A, D, and E) that appear to affect the differentiation of CD4(+) cell T(H)1 and T(H)2 subsets. Other research has shown that herbs such as resveratrol, quercetin, and magnolol may affect transcription factors such as nuclear factor-kappaB and the signal transducer and activator of transcription/Janus kinase pathways with resultant changes in cytokines and inflammatory mediators. Clinically, there have been hundreds of trials looking at the effect of CAM on asthma, allergic rhinitis, and atopic dermatitis. This article reviews the history of CAM and its use among patients, paying special attention to new research focusing on herbals, phytochemicals, and vitamins and their potential interaction with the immune system.

Abstract
The mast cell-mediated immediate-type allergic reaction is involved in many allergic diseases such as asthma, allergic rhinitis, and sinusitis. Stimulation of mast cells starts the process of degranulation resulting in release of mediators such as histamine and an array of inflammatory cytokines. In this report, we investigated the effect of aqueous extract of Teucrium japonicum Houttuyn (Labiatae) (AXTJ) on the mast cell-mediated allergy model and studied its possible mechanisms of action. AXTJ inhibited compound 48/80-induced systemic reactions and serum histamine release in mice. AXTJ decreased immunoglobulin E-mediated passive cutaneous anaphylaxis reaction. AXTJ reduced histamine release and intracellular calcium from rat peritoneal mast cells activated by compound 48/80. In addition, AXTJ attenuated activation of nuclear factor (NF)-kappaB, and downstream tumor necrosis factor (TNF)-alpha expression in phorbol 12-myristate 13-acetate and calcium ionophore A23187-stimulated human mast cells. Our findings provide evidence that AXTJ inhibits mast cell-derived allergic reactions and involvement of intracellular calcium, TNF-alpha, and NF-kappaB in these effects.
