Front Mol Biosci 2023; 10:1263962. [PMID: 38155957 PMCID: PMC10753777 DOI: 10.3389/fmolb.2023.1263962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 11/27/2023] [Indexed: 12/30/2023] Open
Abstract
Introduction: Qi-Xian Decoction (QXD), a traditional Chinese medicine (TCM) formula consisting of eight herbs, has been clinically used to treat asthma. However, the underlying mechanisms have not been completely elucidated. This study aimed to combine metabolomics and network pharmacology to reveal the mechanism of action of QXD in asthma treatment. Methods: An ovalbumin (OVA)-induced asthma mouse model was constructed to evaluate the therapeutic effects of QXD. Serum metabolomics and network pharmacology were combined to study the mechanism of anti-asthma action as well as the potential target, and related biological functions were validated. Results: The QXD treatment has demonstrated significant protective effects in OVA-induced asthmatic mice, as evidenced by its ability to inhibit inflammation, IgE, mucus overproduction, and airway hyperreactivity (AHR). Metabolomic analysis has revealed a total of 140 differential metabolites associated with QXD treatment. In addition, network pharmacology has identified 126 genes that are linked to the effects of QXD, including TNF, IL-6, IL1β, STAT3, MMP9, EGFR, JUN, CCL2, TLR4, MAPK3 and MAPK8. Through comprehensive gene-metabolite interaction network analysis, seven key metabolites have been identified and associated with the potential anti-asthmatic effect of QXD, with palmitic acid (PA) being the most notable among them. In vitro validation studies have confirmed the gene-metabolite interaction involving PA, IL-6, and MAPK8. Furthermore, our research has demonstrated that QXD treatment can effectively inhibit PA-promoted IL-6 expression in MH-S cells and reduce PA concentration in OVA-induced asthmatic mice. Conclusion: The regulation of metabolic pathways by QXD was found to be associated with its anti-asthmatic action, which provides insight into the mechanism of QXD in treating asthma.

J Appl Toxicol 2020; 40:1353-1361. [PMID: 32368827 DOI: 10.1002/jat.3988] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 03/03/2020] [Accepted: 03/17/2020] [Indexed: 12/19/2022]
Abstract
Our recent study has reported that estrogen receptors (ERs) are involved in several types of allergy development. This study aims to investigate the possible relationship between ER activation and development of imiquimod-induced psoriasis-like dermatitis. A mouse model of imiquimod-induced psoriasis-like dermatitis was generated by 5 days of topical application of 5% of imiquimod cream on the back of the ear and the shaved back skin of male BALB/c mice. From the second day of applying 5% imiquimod cream, either ERα selective agonist (propylpyrazoletriol [PPT] 2.5 mg/kg) or ERβ selective agonist (diarylpropionitrile, DPN; 2.5 mg/kg) was administered orally for four consecutive days. Immediately after the final imiquimod cream application, scratching behavior was video monitored for 2 hours. The ear-swelling response was determined by comparing ear thickness before and after the final application of imiquimod cream. Twenty-four hours after the final imiquimod application, back skin tissue and auricular lymph nodes were isolated under isoflurane anesthesia. Oral administration of PPT significantly induced itch behavior and proinflammatory responses, including the levels of interleukin (IL)-17 and IL-22, whereas DPN treatment did not influence either pruritic or proinflammatory responses. In addition, IL-23 contribution by dendritic cells was identified using ER agonists on pretreated lipopolysaccharide (LPS)-stimulated murine bone marrow derived dendritic cells (BMDCs). PPT also significantly enhanced IL-23 secretion by LPS-stimulated BMDCs. Our findings indicate that the activation of ERα, but not ERβ, is directly associated with inflammatory and pruritic responses in a mouse model of the imiquimod-induced psoriasis by enhancing the secretion of IL-23 by dendritic cells.

Abstract
Recent studies have shown that the estrogen receptor α (ERα), but not ERβ, is involved in the proinflammatory and propruritic responses in cutaneous allergy. In addition, results from our recent study showed that while oral administration of the rather ERβ-selective agonist bisphenol A exacerbated the respiratory allergic inflammation, the potential inflammatory reaction in the skin was decreased after administration of bisphenol A. This study aimed to elucidate whether ERα and ERβ are involved in the progression of an allergic airway inflammation. We performed an in vivo experiment using an animal model of allergic airway inflammation using male BALB/c mice to confirm an increase in the proinflammatory response induced by propylpyrazoletriol (PPT), an ERα agonist, and diarylpropionitrile (DPN), an ERβ agonist. Oral administration of PPT or DPN showed a significant increase in the inflammation of the lung and infiltration of eosinophils. While the expression of Th2 cytokines such as interleukin 4 (IL-4) and IL-13 was not affected by exposure to PPT or DPN, administration of these agonists significantly increased the expression of IL-33. The mechanism underlying the development of such allergic inflammatory responses was determined by an in vitro study using the human bronchial epithelial cell line (BEAS-2B) and the human eosinophilic leukemia cell line (EoL-1). Activated cells were exposed to PPT or DPN for 24 h, and the cytokine levels were measured. The IL-33 levels in BEAS-2B cells increased significantly after exposure to PPT or DPN. In addition, pretreatment with PPT or DPN increased the expression of IL-8 in activated EoL-1 cells. Our findings indicate that ERα and ERβ are involved in the proinflammatory response in respiratory allergy, and their effects may be mediated by an increase in the expression of IL-33 and infiltration of eosinophils.

Abstract
In recent years, the bidirectional relationship between the nervous and immune system has become increasingly clear, and its role in both homeostasis and inflammation has been well documented over the years. Since the introduction of the cholinergic anti-inflammatory pathway, there has been an increased interest in parasympathetic regulation of both innate and adaptive immune responses, including T helper 2 responses. Increasing evidence has been emerging suggesting a role for the parasympathetic nervous system in the pathophysiology of allergic diseases, including allergic rhinitis, asthma, food allergy, and atopic dermatitis. In this review, we will highlight the role of cholinergic modulation by both nicotinic and muscarinic receptors in several key aspects of the allergic inflammatory response, including barrier function, innate and adaptive immune responses, and effector cells responses. A better understanding of these cholinergic processes mediating key aspects of type 2 immune disorders might lead to novel therapeutic approaches to treat allergic diseases.

Abstract
AIM The aimof this study is to clarify the effect of cypermethrin (CY) on the oxidative stress (OS) and inflammation status of animals exposed to it and the synergistic role of piperonyl butoxide (PB0). MAIN METHODS Markers of oxidative stress, such as total antioxidant activity (TAC), protein carbonyls, hemoglobin (Hb), reduced glutathione (GSH), thiobarbituric-acid reactive substances (TBARS), along with the telomerase activity in PBMCs (peripheral blood mononuclear cells) were analyzed. KEY FINDINGS Oxidative stress markers showed statistically significant differences between groups in TAC (p b 0.001), GSH (p = 0.018) and CAT activity (p = 0.029), which depended on dose and combined effect of both compounds. Telomerase activity also showed a statistically significant difference between all groups (F = 43.48, df=6, 14, p b 0.001)with cypermethrin, piperonyl butoxide and the co-exposed groups being significantly different fromthe control group (p b 0.05). Significance: The observed results for TBARS, GSH, Hb, TAC, Crbnls and CAT from our exposed groups showed altered levels compared to control groups that could be linked to doses and combined effects of each chemical substance (cypermethrin and piperonyl butoxide). Oxidative stress markers suggest that cypermethrin, piperonyl butoxide and the co-exposed groups, induce oxidative stress as well as induction of telomerase activity.

Abstract
CONTEXT The fruit pulp of Luffa cylindrica Roemer (Cucurbitaceae) (LC) has been used to induce hemostasis, resolve phlegm and clear fever in traditional Korean medicine. However, the efficacy of LC has not been examined in atopic dermatitis (AD). OBJECTIVE A 70% ethanol extract of LC was evaluated to determine anti-inflammation and anti-AD effects in vitro and in vivo. MATERIALS AND METHODS The inhibitory effects of LC on the production of PGE2 and histamine were respectively measured in lipopolysaccharide-treated (1 μg/mL) RAW264.7 macrophages and phorbol-12 myristate 13-acetate (50 nM) and A23187 (1 µM)-stimulated HMC-1 mast cells. The production of AD-related chemokines (RANTES, TARC, and MDC) were evaluated in IFN-γ and TNF-α-stimulated (10 ng/mL, each) HaCaT keratinocytes. LC (10 mg/mouse/d) was topically applied to the dorsal skin and ears of Dermatophagoides farina (Pyroglyphidae)-sensitized Nc/Nga mice for 4 weeks. RESULTS The IC50 values of LC on PGE2 and histamine production were 16.89 and 139.9 μg/mL, individually. The production of TARC and RANTES were inhibited 20% and 12% by LC (50 μg/mL) in HaCaT cells, respectively (p < 0.05). In sensitized-NC/Nga mice, the plasma levels of IgE and histamine were suppressed 36% and 41% by LC, respectively (p < 0.05). LC also reduced hemorrhage, hypertrophy, and hyperkeratosis of the epidermis and infiltration of mast cells in the dorsal skin and ear. DISCUSSION AND CONCLUSION LC can inhibit AD-like skin lesions and reduce the generation of IgE via inhibition of the inflammatory responses. LC has potential as a therapeutic agent to treat allergic diseases, including AD.

Abstract
OBJECTIVE An Asian dust storm (ADS) contains airborne particles that affect conditions such as asthma, but the mechanism of exacerbation is unclear. The objective of this study was to compare immune adjuvant effects and airway inflammation induced by airborne particles collected on ADS days and the original ADS soil (CJ-1 soil) in asthma model mice. METHODS Airborne particles were collected on ADS days in western Japan. NC/Nga mice were co-sensitized by intranasal instillation with ADS airborne particles and/or Dermatophagoides farinae (Df), and with CJ-1 soil and/or Df for 5 consecutive days. Df-sensitized mice were stimulated with Df challenge intranasally at 7 days after the last Df sensitization. At 24 hours after challenge, serum allergen specific antibody, differential leukocyte count and inflammatory cytokines in bronchoalveolar lavage fluid (BALF) were measured, and airway inflammation was examined histopathologically. RESULTS Co-sensitization with ADS airborne particles and Df increased the neutrophil and eosinophil counts in BALF. Augmentation of airway inflammation was also observed in peribronchiolar and perivascular lung areas. Df-specific serum IgE was significantly elevated by ADS airborne particles, but not by CJ-1 soil. Levels of interleukin (IL)-5, IL-13, IL-6, and macrophage inflammatory protein-2 were higher in BALF in mice treated with ADS airborne particles. CONCLUSION These results suggest that substances attached to ADS airborne particles that are not in the original ADS soil may play important roles in immune adjuvant effects and airway inflammation.

Abstract
Aims. Artemisia iwayomogi (AI) has been used for fever reduction, diuresis, and hepatoprotection in Korea. The present study was performed to evaluate the anti-inflammatory and antiatopic dermatitis effects of AI using both in vitro and in vivo systems. Methods. The compositions in AI were analyzed by HPLC. To determine the anti-inflammatory effects of AI, the production of nitric oxide (NO) was measured in lipopolysaccharide treated RAW264.7 cells. Histamine levels were assayed to evaluate the antiallergic effects on MC/9 cells stimulated with phorbol-12 myristate 13-acetate and A23187. Finally, AI (10 mg/mouse/day) was topically applied onto the backs and ears of Dermatophagoides farinae-sensitized Nc/Nga mice for four weeks. Results. Isochlorogenic acid A (20.63 ± 0.26 mg/g), chlorogenic acid (9.04 ± 0.08 mg/g), and scopoletin (8.23 ± 0.01 mg/g) were among the major components of AI. AI inhibited the NO and histamine productions in RAW264.7 and MC/9 cells, respectively. In the mice, the topical application of AI reduced the dermatitis scores in the dorsal skin and ears and reduced the plasma levels of IgE. Conclusions. These results suggest that AI might be explored as a potential therapeutic agent to treat AD, and that the analytic method using HPLC will facilitate the development of quality control for AI.

Abstract
Background Artemisia capillaries Thunb. (AC) has been used to treat inflammatory and hepatic disorders such as hepatic injury, hepatic fibrosis and hepatitis. However, the efficacy of AC against atopic dermatitis (AD), an inflammatory disease, has not been examined. In the present study, AC was evaluated for anti-inflammatory and anti-AD effects using both in vitro and in vivo systems. Methods The contents of six compounds (chlorogenic acid, caffeic acid, isochlorogenic acid A, hyperoside, isoquercitrin and scoparone) in AC were simultaneously assayed using HPLC system. To evaluate the anti-inflammatory effect of AC, NO production was measured in RAW264.7 cell stimulated with 1 μg/mL LPS. Histamine levels were assayed in MC/9 cells stimulated with 50 nM PMA and 1 μM A23187. To examine the role of AC in vivo, AC (10 mg/mouse/day) was topically applied for four weeks the back and ears of Dermatophagoides farinae-sensitized Nc/Nga mice. Protopic ointment (0.1% tacrolimus) was used as a positive control. Results The contents of the six components in AC range from 0.44 to 43.14 mg/g. Chlorogenic acid (21.06 ± 0.08 mg/g) and isochlorogenic acid A (43.14 ± 0.12 mg/g) were major components in AC. AC inhibited NO and histamine production in cells respectively. In D. farinae-sensitized Nc/Nga mice, the topical application of AC reduced dermatitis scores, hemorrhage, hypertrophy and hyperkeratosis of the epidermis in the dorsal skin and ear. The treatment of AC also reduced the plasma levels of histamine (1.5 fold) and IgE (1.4 fold). Conclusions Our results suggest that AC should be explored as a potential therapeutic agent to treat atopic dermatitis and analysis by HPLC will help to improve the quality of AC.

Abstract
BACKGROUND Immunosuppressive environmental chemicals may increase the potency of allergens and thereby play a role in the development of respiratory tract allergies, such as allergic rhinitis and asthma. OBJECTIVES We investigated the association between environmental immunosuppressive chemicals and the allergic airway inflammation development. METHODS We used a mouse model of ovalbumin (OVA)-induced allergic airway inflammation. NC/Nga mice were exposed orally to pesticides parathion (an organophosphate compound) or methoxychlor (an organochlorine compound), or to an insecticide synergist piperonyl butoxide, prior to OVA intraperitoneal sensitization and inhalation challenge. We assessed serum IgE levels, B-cell counts, cytokine production, IgE production in hilar lymph nodes, eosinophil counts, chemokine levels in bronchoalveolar lavage fluid, and cytokine gene expression in the lung. RESULTS Exposure to environmental immunosuppressive chemicals markedly increased serum IgE - IgE-positive B-cells, IgE and cytokines in lymph nodes - eosinophils and chemokines in BALF - IL-10a and IL-17 in the lung. CONCLUSIONS Allergic airway inflammation can be aggravated by prior exposure to immunosuppressive environmental chemicals.
