Gupta P, Dev K, Kaur G. Phytoconstituents as modulator of inflammatory pathways for COVID-19: A comprehensive review and recommendations. Phytother Res 2024. [PMID: 39246209 DOI: 10.1002/ptr.8302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 07/04/2024] [Accepted: 07/12/2024] [Indexed: 09/10/2024]
Abstract
SARS-CoV-2 infection causes disruptions in inflammatory pathways, which fundamentally contribute to COVID-19 pathophysiology. The present review critically evaluates the gaps in scientific literature and presents the current status regarding the inflammatory signaling pathways in COVID-19. We propose that phytoconstituents can be used to treat COVID-19 associated inflammation, several already formulated in traditional medications. For this purpose, extensive literature analysis was conducted in the PubMed database to collect relevant in vitro, in vivo, and human patient studies where inflammation pathways were shown to be upregulated in COVID-19. Parallelly, scientific literature was screened for phytoconstituents with known cellular mechanisms implicated for inflammation or COVID-19 associated inflammation. Studies with insufficient evidence on cellular pathways for autophagy and mitophagy were considered out of scope and excluded from the study. The final analysis was visualized in figures and evaluated for accuracy. Our findings demonstrate the frequent participation of NF-κB, a transcription factor, in inflammatory signaling pathways linked to COVID-19. Moreover, the MAPK signaling pathway is also implicated in producing inflammatory molecules. Furthermore, it was also analyzed that the phytoconstituents with flavonoid and phenolic backbones could inhibit either the TLR4 receptor or its consecutive signaling molecules, thereby, decreasing NF-κB activity and suppressing cytokine production. Although, allopathy has treated the early phase of COVID-19, anti-inflammatory phytoconstituents and existing ayurvedic formulations may act on the COVID-19 associated inflammatory pathways and provide an additional treatment strategy. Therefore, we recommend the usage of flavonoids and phenolic phytoconstituents for the treatment of inflammation associated with COVID-19 infection and similar viral ailments.

Mechanisms of Zhixiao Tang on Anti-Inflammatory Multiple Targets and Multiple Components: Metabonomics Combined with Database Mining Technology. J Inflamm Res 2024; 17:4587-4610. [PMID: 39011417 PMCID: PMC11249118 DOI: 10.2147/jir.s463067] [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: 03/13/2024] [Accepted: 06/26/2024] [Indexed: 07/17/2024] Open
Abstract
Purpose Zhixiao Tang (ZXT), a traditional Chinese compound prescription, has been used clinically to treat pneumonia in China. However, the underlying mechanism of ZXT treatment in pneumonia is still unclear. The present study aimed to reveal the potential mechanism of ZXT in pneumonia using a strategy combining metabolomics and network pharmacology. Methods Initially, the chemical compositions were identified by UPLC-QE-Orbitrap-MS, while the prediction of potential signal pathways was performed through network pharmacology. To assess the anti-inflammatory properties of ZXT in the context of pneumonia, models of 16HBE cells induced by LPS and zebrafish induced by CuSO4 were established to measure levels of inflammatory markers and apoptosis. Subsequently, the differential changes of endogenous metabolites in cells caused by ZXT were examined using metabolomics technology, and the molecular docking analysis of key targets was carried out using Autodock Vina software. Ultimately, the validation of the primary pathways and targets was conducted through quantitative RT-PCR and Western blot techniques. Results A total of 75 compounds were identified through UPLC-QE-Orbitrap-MS analyses. Network pharmacological analysis shows that it plays an anti-inflammatory role in C-type lectin receptor signaling pathway. After ZXT intervention, the inflammatory factors and apoptosis in cells were significantly reduced. Metabonomics analysis showed that 18 metabolites changed significantly. Four key genes were identified, which exhibited partial compatibility with the findings of network pharmacology. Molecular docking analysis confirmed the substantial affinity of the primary targets for ZXT. Furthermore, ZXT exerted a suppressive effect on neutrophil migration, down-regulated the expression of pro-inflammatory cytokine genes, and inhibited the up-regulation of the Dectin-1/SYK/NF-κB signaling pathway. In vivo cell experiments also yielded consistent experimental outcomes. Conclusion This study enhances comprehension of the pharmacological mechanism underlying ZXT's efficacy in pneumonia treatment, thereby establishing a scholarly basis for future research and clinical utilization of ZXT in pneumonia management.

Ann Neurosci 2024; 31:186-203. [PMID: 39156628 PMCID: PMC11325687 DOI: 10.1177/09727531231184698] [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: 02/24/2022] [Accepted: 05/12/2023] [Indexed: 08/20/2024] Open
Abstract
Background Parkinson's disease (PD) is typified by inflammation of dopaminergic neurons leading to the release of various inflammatory mediators. These mediators activate the transcription factor NF-κB, which in turn activates inducible nitric oxide synthase (iNOS), leading to increased inflammation. Purpose This study was intended to study the effect of combination of mangiferin, a specific inhibitor of NF-κB with low-dose nitric oxide (NO) modulators. Methods A total of eight Wistar rats weighing 200-250 g were used in each group. Stereotactic surgery was performed to induce 6-hydroxydopamine (6-OHDA) lesions. The treatment period extended from day 14 to day 42, during which time behavioral tests were performed to evaluate the effects of mangiferin and its combination with NO modulators. On day 42, the brains of the rats were removed for biochemical and molecular analyzes. Results Mangiferin significantly improved locomotor activity and decreased inflammatory chemokines levels in rats with 6-OHDA lesions. Mangiferin therapy decreased myeloperoxidase (MPO) levels and reduced oxidative stress. In particular, caspase-3, caspase-9 and COX-2 activities were significantly reduced after the mangiferin treatment. A combination of 45-µg mangiferin and 10-mg/kg L-NAME showed the greatest improvement in locomotor, behavioral, biochemical, and molecular parameters impaired by 6-OHDA. Conclusion In this study, mangiferin was found to protect rats with 6-OHDA lesions by inhibiting inflammation causing chemokines such as TNF-α and IL-6. Besides, the grouping of iNOS inhibitor L-NAME at a dose of 10 mg/kg with 45-µg mangiferin enhanced the anti-inflammatory and anti-Parkinsonian activity of mangiferin. Consequently, the combination therapy of mangiferin and L-NAME is promising for the treatment of PD. However, clinical trials will be required to evaluate the efficacy of this combination therapy in humans.

Abstract
Inflammatory diseases present a serious health challenge due to their widespread prevalence and the severe impact on patients' lives. In the quest to alleviate the burden of these diseases, nuclear factor erythroid 2-related factor 2 (Nrf2) has emerged as a pivotal player. As a transcription factor intimately involved in cellular defense against metabolic and oxidative stress, Nrf2's role in modulating the inflammatory responses of immune cells has garnered significant attention. Recent findings suggest that Nrf2's ability to alter the redox status of cells underlies its regulatory effects on immune responses. Our review delves into preclinical and clinical evidence that underscores the complex influence of Nrf2 activators on immune cell phenotypes, particularly in the inflammatory milieu. By offering a detailed analysis of Nrf2's role in different immune cell populations, we cast light on the potential of Nrf2 activators in shaping the immune response towards a more regulated state, mitigating the adverse effects of inflammation through modeling redox status of immune cells. Furthermore, we explore the innovative use of nanoencapsulation techniques that enhance the delivery and efficacy of Nrf2 activators, potentially advancing the treatment strategies for inflammatory ailments. We hope this review will stimulate the development and expansion of Nrf2-targeted treatments that could substantially improve outcomes for patients suffering from a broad range of inflammatory diseases.

Abstract
This review aims to provide an in-depth analysis of the pharmacological properties of mangiferin, focusing primarily on its bioavailability and mechanisms of action, and its potential therapeutic applications, especially in the context of chronic diseases. We conducted a comprehensive examination of in vitro and in vivo studies, as well as clinical trials involving mangiferin or plant extracts containing mangiferin. The primary source of mangiferin is Mangifera indica, but it's also found in other plant species from the families Anacardiaceae, Gentianaceae, and Iridaceae. Mangiferin has exhibited a myriad of therapeutic properties, presenting itself as a promising candidate for treating various chronic conditions including neurodegenerative disorders, cardiovascular diseases, renal and pulmonary diseases, diabetes, and obesity. Despite the promising results showcased in many in vitro studies and certain animal studies, the application of mangiferin has been limited due to its poor solubility, absorption, and overall bioavailability. Mangiferin offers significant therapeutic potential in treating a spectrum of chronic diseases, as evidenced by both in vitro and clinical trials. However, the challenges concerning its bioavailability necessitate further research, particularly in optimizing its delivery and absorption, to harness its full medicinal potential. This review serves as a comprehensive update on the health-promoting and therapeutic activities of mangiferin.

Abstract
Xanthones are widely distributed polyphenols, present commonly in higher plants; Garcinia, Calophyllum, Hypericum, Platonia, Mangifera, Gentiana and Swertia. Xanthone tricyclic scaffold is able to interact with different biological targets, showing antibacterial and cytotoxic effects, as well as potent effects against osteoarthritis, malaria, and cardiovascular diseases. Thus, in this article we focused on pharmacological effects, applications and preclinical studies with the recent updates of xanthon´s isolated compounds from 2017-2020. We found that only α-mangostin, gambogic acid, and mangiferin, have been subjected to preclinical studies with particular emphasis on the development of anticancer, diabetes, antimicrobial and hepatoprotective therapeutics. Molecular docking calculations were performed to predict the binding affinities of xanthone-derived compounds against SARS-CoV-2 Mpro. According to the results, cratoxanthone E and morellic acid demonstrated promising binding affinities towards SARS-CoV-2 Mpro with docking scores of -11.2 and -11.0 kcal/mol, respectively. Binding features manifested the capability of cratoxanthone E and morellic acid to exhibit nine and five hydrogen bonds, respectively, with the key amino acids of the Mpro active site. In conclusion, cratoxanthone E and morellic acid are promising anti-COVID-19 drug candidates that warrant further detailed in vivo experimental estimation and clinical assessment.

Abstract
Skin inflammation is a common underlying feature of atopic dermatitis, allergic contact dermatitis and chronic spontaneous urticaria. The pathogenetic mechanisms have not been fully elucidated. The purpose of this study was to examine whether miRNA, by regulating inflammatory mechanisms through the modulation of innate and adaptive immune responses, could play a major role in the pathogenesis of these skin conditions. We conducted a narrative review using the Pubmed and Embase scientific databases and search engines to find the most relevant miRNAs related to the pathophysiology, severity and prognosis of skin conditions. The studies show that miRNAs are involved in the pathogenesis and regulation of atopic dermatitis and can reveal an atopic predisposition or indicate disease severity. In chronic spontaneous urticaria, different miRNAs which are over-expressed during urticaria exacerbations not only play a role in the possible response to therapy or remission, but also serve as a marker of chronic autoimmune urticaria and indicate associations with other autoimmune diseases. In allergic contact dermatitis, miRNAs are upregulated in inflammatory lesions and expressed during the sensitization phase of allergic response. Several miRNAs have been identified as potential biomarkers of these chronic skin conditions, but they are also possible therapeutic targets.

Abstract
Asthma is a chronic respiratory disease characterized by coughing, wheezing, shortness of breath, chest tightness, overproduction of mucus, and expiratory airflow limitation, which affects >300 million people worldwide. It is triggered by the dynamic interplay of genetic factors and environmental exposure. Th17 cells are an emerging subset of CD4+ T cells, which secrete IL-17A. This proinflammatory cytokine has recently been associated with asthma, autoimmune diseases, and inflammatory disorders. The present case-control study was focused on identifying the involvement of the IL-17A gene in asthma pathogenesis among 150 clinically diagnosed asthma patients and 150 healthy controls (HCs) of South Indian origin. To carry out the study, we aimed to screen the genetic variants of rs2275913G/A and rs8193036C/T and also estimated the serum cytokine levels of the IL-17A cytokine of recruited subjects. Further, we evaluated mRNA expression in selected subjects to correlate with the genetic variants. The results revealed that the mean IL-17A serum levels (161.6 ± 380.1 pg/ml vs. 86.75 ± 90.01 pg/ml) and IgE levels (257.7 ± 133.3 pg/ml vs. 311.2 ± 160.5 pg/ml) in asthma patients were significantly high as compared to healthy controls (p < 0.05). The ROC curves were constructed to compare the cytokine levels of asthma patients and HC, and the area under the curve (AUC) for IL-17A cytokine was 0.64, indicating that the test was satisfactory and significant (95 % CI: 0.575-0.709; p < 0.001). Genotyping of rs2275913G/A polymorphism indicated a 1.6-fold risk (95 % CI-1.02-2.56; p = 0.04) for asthma patients compared to healthy controls, whereas no significant association was observed for rs8193036C/T polymorphism with asthma susceptibility. Under genetic models, GA and AA models showed a protective effect against the disease for rs2275913G/A. In contrast, no statistically significant result was observed among the models of rs8193036C/T when adjusted with age and sex. The mRNA expression levels of the gene were statistically high in patients compared to the HCs, with a 1.8-fold change (p < 0.0001). We conclude that the results indicate IL-17A rs2275913G/A is likely to contribute to protection against the disease, while IL-17A rs8193036C/T shows no association with the disease. However, no correlation was identified in serum cytokine levels concerning genotypes. This comprehensive information in the present study might contribute to developing novel therapeutic strategies for treating inflammatory diseases like asthma. Further studies are warranted to understand the diverse functions of IL-17A concerning its longitudinal stability and its response to clinical interventions with large sample sizes in various ethnicities.

Asthma is a life-threatening and chronic inflammatory lung disease that is posing a true global health challenge. The genetic basis of the disease is fairly well examined. However, the molecular crosstalk between microRNAs (miRNAs), target genes, and transcription factors (TFs) networks and their contribution to disease pathogenesis and progression is not well explored. Therefore, this study was aimed at dissecting the molecular network between mRNAs, miRNAs, and TFs using robust computational biology approaches. The transcriptomic data of bronchial epithelial cells of severe asthma patients and healthy controls was studied by different systems biology approaches like differentially expressed gene detection, functional enrichment, miRNA-target gene pairing, and mRNA-miRNA-TF molecular networking. We detected the differential expression of 1703 (673 up-and 1030 down-regulated) genes and 71 (41 up-and 30 down-regulated) miRNAs in the bronchial epithelial cells of asthma patients. The DEGs were found to be enriched in key pathways like IL-17 signaling (KEGG: 04657), Th1 and Th2 cell differentiation (KEGG: 04658), and the Th17 cell differentiation (KEGG: 04659) (p-values = 0.001). The results from miRNAs-target gene pairs-transcription factors (TFs) have detected the key roles of 3 miRs (miR-181a-2-3p; miR-203a-3p; miR-335-5p), 6 TFs (TFAM, FOXO1, GFI1, IRF2, SOX9, and HLF) and 32 miRNA target genes in eliciting autoimmune reactions in bronchial epithelial cells of the respiratory tract. Through systemic implementation of comprehensive system biology tools, this study has identified key miRNAs, TFs, and miRNA target gene pairs as potential tissue-based asthma biomarkers.

Aslani MR, Jafari Z, Rahbarghazi R, Rezaie J, Delkhosh A, Ahmadi M. Effects of crocin on T-bet/GATA-3 ratio, and miR-146a and miR-106a expression levels in lung tissue of ovalbumin-sensitized mice. IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2022; 25:1267-1274. [PMID: 36311189 PMCID: PMC9588310 DOI: 10.22038/ijbms.2022.65622.14433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 09/06/2022] [Indexed: 11/06/2022]
Abstract
Objectives Although various studies have revealed the beneficial effects of crocin (derived from saffron), such as anti-inflammatory, anti-cancer, antioxidant, and immune modulator, however, its exact mechanism is unknown. The present study aimed to investigate the effect of crocin on the expression ratio of T-bet/GATA-3 as an indicator of altered immune responses in the lung tissue of ovalbumin (OVA)-sensitized mice. In addition, the effect of crocin on the expression level of miR-146a and miR-106a in the lung tissue OVA-sensitized mice was investigated. Materials and Methods Mice were randomly divided into five groups (n=6): Control; OVA, OVA + Crocin 25, OVA + Cro 50, and OVA + Cro100 groups. Crocin was administrated intraperitoneally at doses of 25, 50, and 100 mg/kg for five consecutive days. One day after asthma induction, animals were euthanized, and lungs were sampled for pathological and gene expression analysis. Results OVA-sensitization led to increased inflammation and histopathological changes in the lung tissue of mice. In addition, GATA-3 expression increased (P<0.001) and T-bet expression decreased (P<0.001) in OVA-sensitized groups. The T-bet/GATA3 ratio was also reduced markedly in asthma groups (P<0.001). Furthermore, increased expression of miR-146a and miR-106a levels was evident in the lung tissue of OVA-sensitized mice (P<0.001 for both). Intervention with high concentrations of crocin (50 and 100 mg/kg) significantly reduced airway inflammation, GATA-3 expression, miR-146a expression, and miR-106a expression and corrected the T-bet/GATA-3 ratio (P<0.05 to P<0.001). Conclusion Treatment with crocin led to a decrease in the severity of lung inflammation in OVA-sensitized mice, which is probably through the reduction of the T-bet/GATA-3 ratio, and mir-146a and mir-106a expression level.

Abstract
BACKGROUND Asthma, an inflammatory illness of the lungs, remains the most common long-term disease amongst children. This study tried to elaborate the status of apoptosis in asthmatic pulmonary niche after the application of rat mesenchymal stem cells (MSC-CM)-derived secretome. METHODS AND RESULTS Here, we randomly allocated male Wistar rats into three groups (n = 8); Control animals were intratracheally given 50 μl vehicle. In control-matched sensitized rats, 50 μl normal saline was used. In the last group, 50 μl MSC-CM was applied. Two-week post-administration, transcription of T-bet, GATA-3, Bax, Bcl-2 and Caspase-3 was measured by gene expression analysis. Pathological injuries were monitored using H&E staining. The BALF level of TNF-α was measured using ELISA assay. In asthmatic rats received MSC-CM, the expression of T-bet was increased while the level of GATA-3 decreased compared to the S group (p < 0.05). Levels of BALF TNF-α were suppressed in asthmatic niche after MSC-CM administration (p < 0.05). Compared to the asthmatic group, MSC-CM had potential to alter the expression of apoptosis-related genes in which the expression of Bax and Caspase 3 was decreased and the expression of pro-survival factor, Bcl-2 increased (p < 0.05). CONCLUSION Our data notified the potency of direct administration of MSC-CM in the alleviation of airway inflammation, presumably by down regulating apoptotic death in pulmonary niche.

Abstract
The ameliorative effect of Dendrobium fimbriatum polysaccharide (cDFPW1) on ulcerative colitis (UC) was investigated using a dextran-sodium-sulfate-induced (DSS-induced) mouse model in the present study. The results showed that cDFPW1 effectively improved colitis in mice by ameliorating weight loss, disease activity index (DAI) and colonic pathological damage, and by protecting the intestinal barrier function integrity. Moreover, cDFPW1 modulated the composition and metabolism of intestinal microbiota through enhancing Romboutsia, Lactobacillus and Odoribacter, and reducing Parasutterella, Burkholderia-Caballeronia-Paraburkholderia and Acinetobacter in colitis mice. Notably, cDFPW1 significantly restored the homeostasis of Th17/regulatory T (Treg) cells and the expression of specific cytokines. Western blotting of colon tissues showed that cDFPW1 markedly up-regulated the expression of Nrf2 and inhibited the phosphorylation of NF-κB signaling. These results indicated that cDFPW1 possesses the potential of improving UC and its effect on palliating colitis may be connected with the regulation of Nrf2/NF-κB signaling.

Abstract
Respiratory inflammation is caused by an air-mediated disease induced by polluted air, smoke, bacteria, and viruses. The COVID-19 pandemic is also a kind of respiratory disease, induced by a virus causing a serious effect on the lungs, bronchioles, and pharynges that results in oxygen deficiency. Extensive research has been conducted to find out the potent natural products that help to prevent, treat, and manage respiratory diseases. Traditionally, wider floras were reported to be used, such as Morus alba, Artemisia indica, Azadirachta indica, Calotropis gigantea, but only some of the potent compounds from some of the plants have been scientifically validated. Plant-derived natural products such as colchicine, zingerone, forsythiaside A, mangiferin, glycyrrhizin, curcumin, and many other compounds are found to have a promising effect on treating and managing respiratory inflammation. In this review, current clinically approved drugs along with the efficacy and side effects have been studied. The study also focuses on the traditional uses of medicinal plants on reducing respiratory complications and their bioactive phytoconstituents. The pharmacological evidence of lowering respiratory complications by plant-derived natural products has been critically studied with detailed mechanism and action. However, the scientific validation of such compounds requires clinical study and evidence on animal and human models to replace modern commercial medicine.

Abstract
The emergence of an inflammatory condition such as asthma could affect the therapeutic potential of stem cells. Synopsis of previous documents yielded controversial outcomes, leading to a limitation of stem cell-based therapy in the clinical setting. This study aimed to assess the impact of asthmatic serum on the MSCs aging and dynamic growth in vitro. Rats were divided into control and asthmatic groups randomly. The asthmatic change was induced using OVA sensitization. The asthmatic structural changes are monitored by conventional Haematoxylin-Eosin staining. Thereafter, blood samples were taken and sera provided from each group. In this study, primary bone marrow mesenchymal stem cells were cultured in culture medium supplemented with normal and asthmatic serum for 7 days. The MSCs viability was examined using the MTT assay. The expression of the aging-related gene (β-galactosidase), and stemness-related markers such as Sox2, Kfl-4 and p16INK4a were analysed by real-time PCR assay. Histological examination revealed chronic inflammatory remodelling which is identical to asthmatic changes. MTT assay showed a reduction of mesenchymal stem cell viability compared to the control group (P < .05). Real-time PCR analysis revealed a down-regulation of stemness-related markers Sox2, Kfl-4 and p16INK4a coincided with aging changes (β-galactosidase) compared to the control group (P < .05). These data show the detrimental effect of asthmatic condition on bone marrow regenerative potential by accelerating early-stage aging in different stem cells and further progenitor cell depletion. SIGNIFICANCE OF THE STUDY: In such inflammatory conditions as asthma, the therapeutic potential of stem cells may be altered. We demonstrate that serum from asthmatic rats had the potential to reduce the viability of mesenchymal stem cells in vitro. Furthermore, we observed that the expression of the aging-related gene known β-galactosidase was statistically increased in cells co-cultured with asthmatic serum. At the same time, expression of stemness-related markers Sox2, Kfl-4 and p16INK4a down-regulated. These results support the damaging effect of asthmatic condition on bone marrow regenerative ability by inducing early-stage aging in stem cells and additional progenitor cell reduction.

Abstract
We analyzed the ability of mangiferin to suppress cigarette smoke-induced chronic obstructive pulmonary disease. Control rats showed a marked decrease in the ratio of the forced expiratory volume at 0.1 s to forced vital capacity. The decreases in the peak expiratory flow and maximal mid-expiratory flow indicated airway remodeling and enlargement. The expression levels of superoxide dismutase (SOD), heme oxygenase-1 (HO-1), γ-glutamylcysteine synthetase, nuclear factor erythroid 2-related factor 2, and activating transcription factor 4 were increased in the control rats. The levels of oxidative stress, malondialdehyde, and reactive oxygen species peaked after 24 weeks, whereas the SOD and HO-1 levels and the total antioxidant capacity were reduced in control rats. Mangiferin restored the levels of reactive oxygen species, malondialdehyde, SOD, HO-1, and T-AOC to near normal. Increased numbers of infiltrating inflammatory cells were observed in control rats but were significantly reduced by mangiferin. In addition, edema and airway inflammation were reduced by mangiferin.

Abstract
The pathogenesis of skin inflammatory diseases such as atopic dermatitis, acne, psoriasis, and skin cancers generally involve the generation of oxidative stress and chronic inflammation. Exposure of the skin to external aggressors such as ultraviolet (UV) radiation and xenobiotics induces the generation of reactive oxygen species (ROS) which subsequently activates immune responses and causes immunological aberrations. Hence, antioxidant and anti-inflammatory agents were considered to be potential compounds to treat skin inflammatory diseases. A prime example of such compounds is xanthone (xanthene-9-one), a class of natural compounds that possess a wide range of biological activities including antioxidant, anti-inflammatory, antimicrobial, cytotoxic, and chemotherapeutic effects. Many studies reported various mechanisms of action by xanthones for the treatment of skin inflammatory diseases. These mechanisms of action commonly involve the modulation of various pro-inflammatory cytokines such as interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor α (TNF-α), as well as anti-inflammatory cytokines such as IL-10. Other mechanisms of action include the regulation of NF-κB and MAPK signaling pathways, besides immune cell recruitment via modulation of chemokines, activation, and infiltration. Moreover, disease-specific activity contributed by xanthones, such as antibacterial action against Propionibacterium acnes and Staphylococcus epidermidis for acne treatment, and numerous cytotoxic mechanisms involving pro-apoptotic and anti-metastatic effects for skin cancer treatment have been extensively elucidated. Furthermore, xanthones have been reported to modulate pathways responsible for mediating oxidative stress and inflammation such as PPAR, nuclear factor erythroid 2-related factor and prostaglandin cascades. These pathways were also implicated in skin inflammatory diseases. Xanthones including the prenylated α-mangostin (2) and γ-mangostin (3), glucosylated mangiferin (4) and the caged xanthone gambogic acid (8) are potential lead compounds to be further developed into pharmaceutical agents for the treatment of skin inflammatory diseases. Future studies on the structure-activity relationships, molecular mechanisms, and applications of xanthones for the treatment of skin inflammatory diseases are thus highly recommended.

MicroRNA-345-5p acts as an anti-inflammatory regulator in experimental allergic rhinitis via the TLR4/NF-κB pathway. Int Immunopharmacol 2020; 86:106522.

Abstract
Allergic rhinitis (AR) is a common chronic condition characterized by inflammation of the nasal mucosa. The correlation of microRNAs (miRNAs) in AR has been highlighted particularly due to their roles in regulating inflammatory responses. The aim of this study was to explore the anti-inflammatory mechanism by which miR-345-5p regulates the toll-like receptor 4/nuclear factor-κB (TLR4/NF-κB) pathway in mice with AR. Initially, the putative miR-345-5p binding sites on the 3'untranslated region of TLR4 was predicted and verified. AR models were established using ovalbumin, after which the functional role of miR-345-5p in AR was determined using gain- and loss-of-function approaches. We found that miR-345-5p was poorly expressed in nasal mucosal tissues of mice with AR. Meanwhile, TLR4 expression and the TLR4/NF-κB pathway were identified to be promoted, which were then suppressed in the presence of overexpressed miR-345-5p. In addition, nasal epithelial cell apoptosis and fibrosis were inhibited in response to miR-345-5p overexpression and TLR4 silencing. Furthermore, miR-345-5p overexpression and TLR4 silencing were observed to decrease Th2 cells, expression of pro-inflammatory factors, but to increase Th1 cells and expression of anti-inflammatory factors. This study demonstrates an important role of miR-345-5p in alleviating the inflammatory response in mice with AR by inhibiting the TLR4/NF-κB pathway. Therefore, a better understanding of this process may aid in the development of novel therapeutic agents of AR.

Abstract
Allergic asthma is an inflammatory disease involving the Th1/Th2 cell imbalance in the peripheral blood. Repeated herbal acupoint sticking (RHAS) has been used for hundreds of years in China to relieve the recurrence of allergic asthma, and it is still practiced today. Thus, we explored the effect on allergic asthma relapse and the underlying immunoregulatory mechanism in this study. Here, we enrolled 50 allergic asthma participants, and 38 of them completed the treatment and follow-up (the allergic asthma group). In addition, 13 healthy participants (the control group) were enrolled. The recurrence number of allergic asthma participants and asthma control test (ACT) were used to evaluate the effect of treatment on relieving allergic asthma recurrence. Flow cytometry was performed to analyze the levels of Th1 and Th2 cells in the peripheral blood. The serum levels of IgE, IFN-γ, and IL-4 were detected by ELISA. (1) In the allergic asthma group, compared to before the first treatment, the recurrence number of allergic asthma participants decreased and the ACT score increased at end of the last treatment, 18 and 30 weeks of the trial (P < 0.05). At 18 and 30 weeks of the trial, the recurrence number of allergic asthma participants was less and the ACT score was higher than the ones from the same period last year in the allergic asthma group (P < 0.05). Compared to before the first treatment, the percentage of Th1 cell did not change significantly, the percentage of Th2 cell decreased, and the Th1/Th2 cell ratio increased in the allergic asthma group by the end of the last treatment (P < 0.05). Meanwhile, the release of IgE and IL-4 reduced (P < 0.05), and the release of IFN-γ did not significantly change in the allergic asthma group. (2) Compared with the control group, the serum levels of IgE and IL-4 and the percentage of Th2 cell were higher, and the Th1/Th2 cell ratio was lower in the allergic asthma group (P < 0.05). There was no significant difference between Th1 cell and IFN-γ before the first treatment. (3) Compared with the control group, the IgE levels and the percentage of Th2 cell were higher in the allergic asthma group (P < 0.01). Simultaneously, there was no significant difference between Th1 cell, the Th1/Th2 cell ratio, and the serum levels of IFN-γ and IL-4 by the end of the last treatment. The data suggested that RHAS reduced the amount of Th2 cell and elevated the Th1/Th2 cell ratio, thereby alleviating the inflammatory responses in the allergic asthma participants.

Abstract
Mangiferin, a natural compound isolated from Mangifera indica L, was incorporated in glycerosomes, ethosomes and alternatively in glycerol-ethanol phospholipid vesicles (glycethosomes). Actually, only glycethosomes were able to stably incorporate the mangiferin that was loaded at increasing concentrations (2, 4, 6, 8 mg/mL). The morphology, size distribution, rheological properties, surface charge and entrapment efficiency of prepared vesicles were deeply measured. All vesicles were mainly spherical, oligolamellar, small in size (~145 nm) and negatively charged (~-40 mV), as confirmed by cryo-TEM observation and dynamic laser light scattering measurements. The higher concentration of mangiferin (8 mg/mL) allowed an increase of vesicle mean diameter up to ~288 nm. The entrapment efficiency was inversely proportional to the amount of loaded mangiferin. In vitro studies performed by using human abdominal skin, underlined that, the dose-dependent ability of vesicles to promote mangiferin retention in epidermis. In addition, glycethosomes were highly biocompatible and showed a strong ability to protect in vitro the fibroblasts against damages induced by hydrogen peroxide. In vivo results underlined the superior ability of mangiferin loaded glycethosomes respect to the mangiferin dispersion to promote the heal of the wound induced by TPA, confirming their potential application for the treatment of psoriasis or other skin disorders.

J Orthop Surg Res 2019; 14:325. [PMID: 31623650 PMCID: PMC6798411 DOI: 10.1186/s13018-019-1387-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Accepted: 09/23/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND TLR2 (Toll-like receptor 2) signaling and its downstream proinflammatory cytokines are considered to be important in the progression of peri-implantitis. A natural medicine, mangiferin has exhibited modulatory effect on TLR2 signaling and anti-inflammatory effects on different diseases. The objective of the present study is to investigate the effect of mangiferin on peri-implantitis and the potential mechanisms by administering this drug to an experimental peri-implantitis mouse model. METHODS Maxillary left first, second, and third molars of mice were extracted, and dental implants were placed in the region of the maxillary left second molars. Then, peri-implantitis was induced by tying ligatures around implants, and mangiferin was given orally to the mice. After 6-week mangiferin treatment, bone loss around the implants was detected using micro-computerized tomography (micro-CT). Alveolar bone and inflammatory infiltrate in peri-implant tissues were examined using hematoxylin and eosin (H&E) staining. Production of interleukin-6 (IL6), a TLR2 downstream proinflammatory cytokine, in the tissue surrounding implants was measured using quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) analysis. IL6 protein expression and TLR2 signaling pathway activation in peri-implant tissues were detected using western blot analysis. RESULTS Micro-CT demonstrated reduced bone loss in peri-implantitis upon mangiferin administration. Additionally, H&E staining showed more alveolar bone and less inflammatory infiltrate in peri-implant tissues after mangiferin application. Moreover, qRT-PCR analysis demonstrated lower levels of IL6 gene expression, and western blot analysis showed decreased protein expression of IL6 and TLR2, and suppressed phosphorylation of TLR2 downstream nuclear factor-κB, p38 mitogen-activated protein kinase, and c-Jun N-terminal kinase after mangiferin treatment. CONCLUSIONS These results suggest the suppressive effect of mangiferin on bone damage and inflammatory infiltrate in peri-implantitis. These therapeutic effects may be associated with inhibited IL6 production and reduced TLR2 signaling activation in peri-implant tissues.

Abstract
Background The methylation status of RUNX3 promoter region, its impact on RUNX3 gene expression, and Th1/Th2 imbalance are unknown in bronchiolitis. This study aimed to explore the predictors of bronchiolitis developing into asthma. Material/Methods The methylation status of RUNX3 promoter was assessed using Illumina HiSeq platform method. The relative RUNX3 mRNA levels in PBMCs were measured by qRT-PCR. Serum IL-4 and IFN-γ concentrations were measured by ELISA. Results A series of sites with significantly higher levels of methylation as compared to their corresponding controls were identified, including 24 sites in group Ba vs. group Cn, 13 sites in group Ba vs. group Ca, 7 sites in group Ba vs. group Bn, 16 sites in group Bn vs. group Cn, 11 sites in group Ca vs. group Cn, and 23 sites in group B vs. group C; P<0.05. The relative mRNA levels in group Ba were significantly lower than those in groups Cn, Ca, Bn; P<0.05. The serum IL-4 concentrations in group Ba were significantly higher than those in group Cn; P<0.05. The serum IFN-γ concentrations in group Ba were significantly lower than those in groups Cn, Ca, Bn; P<0.05. Correlation analysis showed that differentially methylated RUNX3 promoter region sites were significantly negatively correlated with levels of relative RUNX3 mRNA and IFN-γ, and were significantly positively correlated with IL-4 levels. Conclusions The methylation status of RUNX3 promoter region plays a role in Th1/Th2 imbalance by silencing RUNX3 gene expression, which can serve as predictive marker for the development of bronchiolitis into asthma.

Abstract
Asthma is a common obstructive airway disease characterized by inflammation and remodeling with a progressive decline in lung function. Fangxiao Formula (FXF) is an herbal medicine that has achieved significant clinical benefits toward asthma patients, but the relevant mechanism has not yet been clarified. The aim of this study was to determine the inhibitory effects of FXF on airway inflammation and remodeling, and investigate the activities of TGF‑β/Smads signaling pathway in the rat asthma model. Rats were sensitized by ovalbumin (OVA) for six weeks to establish the asthma experimental model. OVA-challenged animals were randomly divided into 5 groups and received different concentrations of FXF or dexamethasone. The animals in blank control group received saline only. Lung tissues were collected and analyzed for determining the inflammatory cells infiltration, HE and PAS staining, airway wall thickness and collagen deposition. The productions of inflammatory cytokine productions were analyzed by ELISA in the bronchoalveolar lavage (BAL) fluid. Immunohistochemical analysis was performed to measure the expression of α-SMA and PCNA in lung tissue after the treatment of FXF. The levels of TGF-β were assessed by both immunohistology and western blotting, and the expression of p-Smad2/3 proteins were determined by western blotting analysis. Our results indicated that FXF attenuated the infiltration of inflammatory cells, decreased the production of Th2 cytokines and simultaneously increased the levels of Th1 cytokine in the asthma rat model. In addition, FXF reduced allergen-induced increased airway wall thickness, goblet cell hyperplasia and collagen deposition. Furthermore, the expression levels of TGF-β and p-Smad3 were obviously reduced after the treatment of FXF. These results indicate that FXF alleviates airway inflammation and remodeling by restoring the balance of Th1/Th2 cytokines and the TGF-β/Smad-3 pathway, therefor providing potential therapeutic approach for asthmatic patients.

Abstract
Lactic acid bacteria are known to have various health-promoting effects and are highly expected to find applications in anti-allergic food materials. In this study, we focused on Lactobacillus helveticus SBT2171 (LH2171), which reportedly modifies some unique immune responses and ameliorated symptoms of patients allergic to mites and house dust in the previous studies. We examined the effect of LH2171 on cytokine production by antigen-stimulated murine naïve splenocytes in vitro and demonstrated that it inhibited IL-4 and IL-13 production while enhancing IFN-γ and IL-10 production. Then, we examined the anti-allergic effect of LH2171 in vivo using a murine model of pollen allergy and found that LH2171 reduced the sneezing frequency when orally administered to mice. We successfully confirmed the immune modulatory activity of LH2171 and its anti-allergic activity against inhaled antigens. These evidences would contribute to identifying the anti-allergic mechanism of LH2171.Abbreviations: ALDH: aldehyde dehydrogenase; EGCG: epigallocatechin gallate; LAB: lactic acid bacteria; LH2171: Lactobacillus helveticus SBT2171; NALT: nasal-associated lymphoid tissue; OVA: ovalbumin.

Abstract
Asthma is the most prevalent chronic respiratory disease worldwide. Garlic extracts have long been used as a food source and in traditional medicine. Crude extracts of garlic are used as an anti-inflammatory agent and have been reported to exhibit antiasthmatic properties. However, molecular mechanisms of garlic extracts in the context of antiasthmatic airway inflammation are still unclear. In this study, the antiasthmatic effect of garlic extracts on Th1, Th2, and Th3 cytokine profiles and immunoregulatory mechanism were explored using an animal model of allergic asthma. Garlic extracts significantly reduced total inflammatory cell counts and eosinophil infiltration and decreased the production of Dermatophagoides pteronyssinus IgE in serum and Th1/Th2/Th3 cytokine in bronchoalveolar fluid. Enzyme-linked immunosorbent assay analysis demonstrated that garlic extracts downregulated the levels of cytokines and chemokines, namely Th2-related IL-4, IL-5, and IL-13; but they simultaneously upregulated Th1-related IFN-γ, IL-12, and Th3-related IL-10 and TGF-β expression in BALF. The mechanism may be ascribed to the modulation of Th1-, Th2-, and Th3-related cytokine imbalance.

Abstract
Pinelliae Rhizoma Praeparatum cum Alumine (PRPCA) is an important traditional processed herbal medicine mainly used for treating phlegm in China for more than 2000 years. In our previous studies, extraction optimization, characterization, and bioactivities of total polysaccharides from PRPCA were investigated. In this study, further purification of these polysaccharides was performed. Two polysaccharides named neutral fraction of total polysaccharides-II (TPN-II) and acidic fraction of total polysaccharides-II (TPA-II) were obtained by gradient ion-exchange chromatography followed by gel-permeation chromatography. Results of scanning electron microscopy (SEM) analysis in the present study showed that TPN-II had a tight structure with a rough and uneven surface, while TPA-II had a relative homogeneous surface and a loose structure. Further studies indicated that TPN-II was a homosaccharide mainly composed by glucose with a molecular weight of 8.0 kDa. TPA-II was mainly composed of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose and arabinose in a molar ratio of 2.1, 2.3, 1.7, 10.6, 2.6, 14.2, and 2.5, with a molecular weight of 1250 kDa. The nuclear magnetic resonance (NMR) results indicated that α and β form glycoside bonds existed in TPN-II and TPA-II, and TPN-II was composed of α-glucopyranose. In addition, both purified polysaccharides have significant anti-inflammatory effects on mucus secretion of human airway epithelial NCI-H292 cells without cytotoxicity. Compared with TPN-II, TPA-II exhibited more significant anti-inflammatory effects on lipopolysaccharide (LPS)-induced airway inflammation by regulating levels of interleukin-4 (IL-4) and interferon-γ (IFN-γ) and inhibiting mucus secretion. The results suggest that polysaccharides from PRPCA could be explored as therapeutic agents in treating inflammation and over secretion of mucus in asthma.

Abstract
Achieving the optimal clinical outcome of mesenchymal stem cells (MSCs) is particularly dependent on fundamental understanding of therapeutic mechanisms. The current study was focused on the possible mechanisms by which rat bone marrow-derived mesenchymal stem cells (rBMMSCs) and/or conditioned media (CM) display broad immunomodulatory properties for ameliorating of asthma-related pathological changes. Male rats were divided equally into four experimental groups (n = 6): healthy rats received 50 μl PBS intravenously (group C), sensitized rats received 50 μl PBS intravenously (group OVA), sensitized rats received 50 μl CM intravenously (group OVA + CM), and sensitized rats received 50 μl PBS intravenously containing 2 × 106 rBMMSCs (group OVA + MSCs). After 2 weeks, the expression of interleukin (IL)-5, IL-12 and INF-γ, ICAM-1, and VCAM-1; pathological injuries; and the homing of MSCs into the lung tissues were assessed. Our results showed that systemic delivery of rBMMSCs, but not CM, returned the expression of IL-5, IL-12 and INF-γ, ICAM-1, and VCAM-1 and pathological injuries in the lung tissues of asthmatic groups to the near level of control group (p < 0.001 to p < 0.05). Moreover, rBMMSCs had potential to successfully recall to asthmatic niche in cell-administrated rats. However, no regulatory function was observed by MSC-CM. Collectively, our data notified the potency of MSCs in ameliorating OVA-mediated airway inflammation in a rat model of asthma presumably by regulating endothelial expression of leukocyte-selective cell adhesion molecules in lung tissue.

Abstract
AIMS With respect to recent advantage in stem cell application, given the concern reported previously after stem cell transplantation, mesenchymal stem cell-derived conditioned media (MSC-CM) could be a potential approach to guarantee more safety and efficient outcomes than the current stem cell-based regenerative therapies. MAIN METHODS Male rats were assigned into four experimental groups (n = 6); healthy rats (C group), OVA sensitized rats (S group), OVA sensitized rats received a single dose of 50 μl CM intravenously (S group + SD-CM) and OVA sensitized rats received repeated doses of 50 μl CM intravenously (S group + RD-CM). Two weeks post-allergen challenge, the therapeutic effects of systemic administrated CM in single and repeated dosages were investigated by monitoring the transcription of T-bet, GATA-3, IL-4 and IFN-γ genes along with pathological changes in asthmatic lung tissue. IL-4 and IFN-γ levels and IFN-γ/IL-4 ratio were further evaluated in sera. KEY FINDINGS Our data revealed that the systemic introduction of CM in repeated dosages could significantly reduce pathological injures in OVA-sensitized rats by the modulation of expression of T-bet and GATA-3 in lung tissues and interleukins levels (p < 0.001 to p < 0.05). In contrary, CM in single dosage did not yield any beneficial effect. SIGNIFICANCE Overall, we indicated that systemic administration of CM in repeated dosages, but not in single dose, could be strategic approach in amelioration of asthmatic changes, presumably by the regulating the differentiation of naive CD4 T cells into Th1/Th2 effector cells via modulation of T-bet and GATA-3 expression in OVA-sensitized male rats.

Abstract
Current study was designed to evaluate protective effect of mangiferin and its interaction with low dose of nitric oxide (NO) modulators in complete Freund's adjuvant (CFA) inoculated rats. Male wistar rats (200-300 g, n = 8 per group) were used in the study. On day ''0'' of study arthritis was induced in rats by injecting 0.2 ml CFA in sub-planter region of right hind paw of animals. Treatment with methotrexate (5 mg/kg), mangiferin (10-30 mg/kg) alone and in combination with NO modulators was given (i.p.) from days 14 to 28. After 28 days, blood and joint synovial fluid was collected for biochemical analysis and rat paws were excised to estimate MDA and SOD in tissue (paw) homogenates. CFA inoculation significantly increases (1) arthritic index, (2) ankle diameter, (3) paw volume, and (4) serum TNF-α, IL-6, IL-1β, and synovial TNF-α levels (p < 0.001). The serum Th1 (IFN-γ) and Th2 (IL-4) cytokine levels, MDA levels in rat paw tissue homogenates and serum NF-κB levels were also found significantly increased. Significant decrease in serum IL-10 levels and SOD activity was found after CFA inoculation. These CFA-induced arthritic changes, cytokine profile, and oxidative stress markers were significantly reversed by mangiferin (10-30 mg/kg) treatment alone and in combination with L-arginine and L-NAME nitric oxide modulators (p < 0.05). Treatment with methotrexate (5 mg/kg) also significantly reversed these adjuvant changes (p < 0.05). However, effect of methotrexate was less marked as compared to mangiferin (30 mg/kg) alone and in combination with L-NAME (10 mg/kg), but was comparable or slightly better than mangiferin (10 and 20 mg/kg). Thus, on the basis of our findings, we can suggest that interaction of mangiferin with nitric oxide modulators may have therapeutic value for chronic inflammatory disease such as RA.

Chun JM, Lee AR, Kim HS, Lee AY, Gu GJ, Moon BC, Kwon BI. Peucedanum japonicum extract attenuates allergic airway inflammation by inhibiting Th2 cell activation and production of pro-inflammatory mediators. JOURNAL OF ETHNOPHARMACOLOGY 2018; 211:78-88. [PMID: 28919220 DOI: 10.1016/j.jep.2017.09.006] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/29/2016] [Revised: 09/05/2017] [Accepted: 09/09/2017] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The root of Peucedanum japonicum Thunberg is traditionally used to treat coughs, colds, headache and inflammatory diseases in Korea and Japan. Its effects on allergic lung inflammation have not been investigated. AIM OF THE STUDY To investigate the anti-asthmatic effects of Peucedanum japonicum extract (PJE) using a murine model of asthma and a lipopolysaccharide (LPS)-stimulated macrophage cell line. MATERIALS AND METHODS Mice underwent two rounds of sensitization with ovalbumin 1 week apart followed by four intranasal ovalbumin challenges on days 13-16. The control group received saline only. Two ovalbumin-sensitized groups were orally administered vehicle or PJE (200mg/kg) 5 days a week starting 1 week before the first ovalbumin sensitization. The third group was orally administered the asthma medication Montelukast (10mg/kg) on days 12-16. All animals were sacrificed on day 17. The lungs were assessed for histological features, inflammatory cell infiltration, Th2 cell activation and GATA-binding protein-3 (GATA-3) expression. The bronchoalveolar lavage fluid (BALF) was assessed for type 2 cytokine levels. The effect of PJE on the in vitro Th2 polarization of naïve CD4+ splenocytes and the production of pro-inflammatory mediators and cytokines by LPS-stimulated RAW 264.7 cells was evaluated. RESULTS PJE treatment inhibited OVA-induced inflammatory cell infiltration, eosinophilia, Th2 activation, and GATA-3 expression in the lung, reduced the interleukin (IL)-5 and IL-13 levels in BALF, down-regulated Th2 activation in vitro, and inhibited the macrophage production of inducible nitric oxide, cyclooxygenase-2, tumor necrosis factor-α, and IL-6. CONCLUSION PJE attenuated allergic airway inflammation by inhibiting Th2 cell activation and macrophage production of inflammatory mediators. Peucedanum japonicum may be candidate therapy for allergic lung inflammation.

Abstract
This study was designed to investigate the correlation of vitamin D receptor (VDR) gene polymorphism with bronchial asthma in children. Seventy patients admitted to Daqing Longnan Hospital and diagnosed as bronchial asthma for the first time from April 2015 to May 2017 were selected as observation group. Patients received routine treatment and intervention. Seventy healthy subjects admitted to hospital during the same period were enrolled as the control group. Vitamin D gene polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism assay; the levels of total serum immunoglobulin E (IgE) in the two groups were determined by electrochemiluminescence immunoassay; lung function levels in patients were measured using PowerCube (Germany) pulmonary function instrument before and after treatment, and the relationship between VDR gene polymorphism and lung function in children with bronchial asthma was analyzed. The difference in comparison of base frequency of rs1544410 locus of VDR gene had no statistical significance between the two groups (P>0.05). The locus CC frequency of rs7975232 of VDR gene in observation group was lower in the observation group than that in the control group (P<0.05); the locus AC and AA frequencies of rs7975232 of VDR gene were higher in the observation group than those in the control group (P<0.05). The level of vitamin D was lower in the observation group than that in the control group (P<0.05); the level of total serum IgE was higher in the observation group than that in the control group (P<0.05). The forced expiratory volume in 1 sec (FEV1), peak expiratory flow (PEF) and the ratio of FEV1 to forced vital capacity (FVC) in children with bronchial asthma in the observation group were higher after treatment than those before treatment (P<0.05). The correlation research displayed that VDR gene polymorphism was negatively correlated with lung function levels in children with bronchial asthma (P<0.05). The results showed that children with bronchial asthma are often accompanied by different degrees of changes in VDR gene polymorphism, which is negatively correlated with the severity of asthma, so vitamin D should be strengthened to ameliorate the prognosis of children.

Abstract
Immunoglobulin E (IgE) is involved in the onset of allergic reaction, and the suppression of IgE production leads to alleviation of allergic symptoms. We found that mango peel ethanol extract (MPE) significantly suppresses IgE production by human myeloma cell line U266 cells, suggesting that MPE has an anti-allergic effect by inhibiting the production of IgE. Although mangiferin is contained in mango, which suppresses IgE production by U266 cells, it was not contained in MPE. We investigated the suppressive effect of MPE in 2,4-dinitrofluorobenzene (DNFB)-induced allergic contact dermatitis model mice. The elevation of serum IgE level was significantly suppressed by oral administration of MPE. Intake of MPE also suppressed the expression level of IL-4 in the DNFB-challenged ears, suggesting that MPE suppresses the IL-4-mediated maturation into IgE-producing cells. Our findings indicate that MPE has a potential to alleviate the increase in serum IgE level that is feature of type I allergy.

Abstract
Sulfur dioxide (SO2) is one of potential risk factors for induction and/or exacerbation of asthma, but the underlying mechanisms are not well understood. In this study, we investigate the role of SO2 in asthma using a classical asthmatic model with allergic airway inflammation by treating C57BL/6 mice with ovalbumin (OVA) and/or 10 mg/m3 SO2. Our results showed that SO2 exposure alone induced slight pathological changes but did not significantly increase inflammatory cell counts, pro-inflammatory cytokine expression, and mucus production in the airway of mice, whereas SO2 exposure in OVA-induced asthmatic mice caused marked pulmonary pathological changes and significantly increased the counts of eosinophil-rich leukocytes compared with OVA alone asthmatic mice. The expression of MUC5AC, TNF-α, Th2 cytokines (IL-4, IL-5, and IL-13) and STAT6 was further up-regulated in OVA plus SO2 treated mice compared with OVA alone treated mice. In addition, exposure to SO2 alone markedly elevated STAT6 mRNA levels and hydrogen peroxide (H2O2) content in the lung. These findings suggest that SO2 amplifies Th2 inflammatory responses in OVA-induced asthmatic mice by activating STAT6, which can further induce Th2 cytokine expression. Induction of STAT6 expression might be an important mechanism underlying the increased risk for asthma after environmental exposure.

Abstract
Nitrogen dioxide (NO2) is a major air pollutant. Epidemiologic studies have found that NO2 exposure is associated with an increased risk of asthma. Nevertheless, the potential molecular mechanisms remain unclear. In this study, we investigated the effect of NO2 inhalation on the occurrence of allergic airway inflammation and its underlying mechanisms. Firstly, male Wistar rats were exposed to 2 and 5 mg/m3 NO2 (28 days, 5 h/day). The results showed that NO2 exposure could induce pulmonary inflammatory response, mucus formation, and Th1/Th2 imbalance in the lung of normal rats, resulting in allergic asthma-like features. Secondly, male Wistar rats were exposed to 5 mg/m3 NO2 (42 days, 5 h/day), sensitized with ovalbumin (OVA), challenged with aerosolized OVA, and characterized in asthma models. Results showed that NO2 exposure aggravated lung inflammation in the OVA-sensitized rats, accompanied by the increase in inflammatory cell infiltration, mucus hypersecretion, and collagen deposition. Furthermore, NO2 exposure promoted the increase in the expression of mucin gene (MUC5AC) and pro-inflammatory factors [interleukin (IL)-1β, intercellular adhesion molecule-1 (ICAM-1), and IL-6] as well as serum OVA-specific immunoglobulin E (IgE) production. Taken together, we established that NO2 exposure promotes allergic airway inflammation and increases the asthma susceptibility. The underlying mechanisms involve the promotion of activation of interleukin-4/signal transducer and activator of transcription-6 (IL-4/STAT6) pathway [IL-4 receptor (IL-4R) α, janus kinase (JAK) 1, JAK 3, and STAT6] and related transcription factor [T cell-specific protein-tyrosine kinase (Lck), extracellular-regulated kinase (ERK)1/2, and nuclear factor-κB (NF-κB)]. In particular, the imbalance of Th1/Th2 cell differentiation [IL-4, interferon (IFN)-γ, GATA-binding protein-3 (GATA-3), and T-box expressed in T cells (T-bet)] plays a pivotal role in NO2-induced inflammatory responses. These findings may provide a better understanding of mechanism of NO2-associated respiratory diseases.

Deficiency of KLF4 compromises the lung function in an acute mouse model of allergic asthma. Biochem Biophys Res Commun 2017; 493:598-603.

Abstract
Asthma is a chronic inflammatory disease of the airways and the mechanisms are not fully understood. Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of monocytes, granulocyte and myeloid cells at early stage of differentiation. They possess phenotypic plasticity and regulate airway inflammation. We recently reported that Kruppel-like factor 4 (KLF4) regulates MDSC differentiation into fibrocytes, emerging effectors in chronic inflammation. However, the role of KLF4 in asthma is not known. Thymic stromal lymphopoietin (TSLP) is an epithelial cell-derived cytokine and a key initiator of allergic airway inflammation. Given the fact that TSLP promotes Th2 cytokine production that increases MDSC differentiation into fibrocytes, we postulate that KLF4 regulates asthma in a TSLP-dependent manner. In this study, we utilized a model of allergic asthma with ovalbumin challenge (OVA). We found that upon OVA treatment the wild type mice had increased MDSC infiltration into the lung, up-regulation of KLF4 and TSLP gene expression, and higher levels of Th2 cytokines including IL4 and IL13. Consistently, lack of KLF4 expression in monocytes and lung epithelial cells resulted in decreased TSLP expression and lower levels of Th2 cytokines in mice, and fibrocyte generation was compromised. KLF4 deficiency in these cells also led to decreased airway hyperresponsiveness (AHR), a cardinal feature of asthma, as assessed by whole body plethysmography. Moreover, lung fibrosis as measured by trichome staining was attenuated and the population of CD45 + COL1A1+ fibrocytes was diminished in this setting. Together, our results suggest that KLF4 regulates asthma development in a TSLP- and fibrocyte-dependent manner.

Abstract
Short chain fatty acids (SCFAs) are postulated to modulate the immune development of neonates via epigenetic regulations such as histone deacetylase (HDAC) inhibition. In the context of atopic diseases, the inhibition of HDAC maintains T-cell homeostasis and induces naïve T-cell differentiation into adaptive Treg, which regulates the production of anti-inflammatory cytokines and suppression of Th2 immune responses. We investigated the structure-inhibition relationships of SCFAs with class I HDAC3 and class IIa HDAC7 using in silico docking simulation and the in vitro human recombinant HDAC inhibition assay. In silico docking simulation demonstrated that the lower binding energy of SCFAs toward HDACs was associated with the longer aliphatic chain length of SCFAs. Conversely, branching of SCFAs increased their binding energies toward both HDAC3 and HDAC7. The in vitro HDAC inhibition assay revealed that SCFAs more potently inhibit HDAC3 than HDAC7, with butyric acid being the most potent HDAC3 inhibitor among SCFAs (IC50 = 0.318 mM). In conclusion, our findings inform novel structural relationships between SCFAs and HDAC3 versus HDAC7. Future investigation of human disposition of SCFAs is important to establish their effects on innate versus adaptive immunity.

Abstract
Asthma is tightly related to the imbalance of Th1/Th2 cells, and Runx3 plays a pivotal role in the differentiation of T helper cells. The present study aimed to investigate dysregulated microRNAs that may target Runx3 in CD4+ T cells from asthmatic patients and reveal Runx3 function in Th1/Th2 balance regulation. We detected the levels of Th1- and Th2-related cytokines by ELISA and analyzed the differentiation marker gene of T helper cells by qRT-PCR. Results indicated that an imbalance of Th1/Th2 cells was present in our asthmatic subject. Runx3 expression was reduced in the CD4+ T cells from asthmatic patients. Overexpression of Runx3 could restore the Th1/Th2 balance. After performing microRNA microarray assay, we found a series of microRNAs that were considerably altered in the CD4+ T cells from asthmatic patients. Among these upregulated microRNAs, eight microRNAs that may target Runx3 were selected by bioinformatics prediction. Five microRNAs, namely miR-371, miR-138, miR-544, miR-145, and miR-214, were confirmed by qRT-PCR and selected as candidate microRNAs. Luciferase reporter assay showed that these five microRNAs could directly target the 3'-UTR of Runx3. However, only simultaneous inhibition of these five microRNAs could alter the expression of Runx3. Most importantly, only simultaneous inhibition could improve the Th1/Th2 balance. Thus, we suggest that miR-371, miR-138, miR-544, miR-145, and miR-214 can modulate the Th1/Th2 balance in asthma by regulating Runx3 in a combinatorial manner.

Abstract
Allergic rhinitis (AR) is one of the most common allergic diseases, which adversely affect patients' quality of life. Mahuang Fuzi Xixin decoction (MFXD) has been widely used to treat AR in clinics in Asian countries. This study investigated the effect and possible therapeutic mechanisms of MFXD in the treatment of AR. A Wistar rat model of ovalbumin- (OVA-) induced AR was established and then treated with three doses of MFXD; AR symptoms, serum total immunoglobulin E, histamine, histopathological features, and release and expression of factors related to type 1 helper T (Th1) and type 2 helper T (Th2) responses were analyzed. Our study demonstrated that MFXD has a good therapeutic effect on OVA-induced allergic inflammation in an AR rat model as manifested in reduced frequencies of sneezing and nasal scratching and in reduced serum levels of total IgE and HIS. In addition, MFXD regulates imbalance in Th1/Th2 cells caused by AR by simultaneously attenuating Th1 and Th2 responses, such as by reducing the serum levels of IFN-γ and IL-4 and mRNA expression levels of IFN-γ, IL-4, GATA-3, and STAT-6. This study provided valuable information on the immunoregulatory effect of MFXD for the treatment of AR in future clinical studies.

Abstract
Asthma is characterized by chronic inflammation, goblet cell hyperplasia, the aberrant production of the Th2 cytokines, and eosinophil infiltration into the lungs. In this study, we examined the effects of baicalein, wogonin, and Scutellaria baicalensis ethanol extract on ovalbumin (OVA)-induced asthma by evaluating Th1/Th2 cytokine levels, histopathologic analysis, and compound 48/80-induced systemic anaphylaxis and mast cell activation, focusing on the histamine release from rat peritoneal mast cells. Baicalein, wogonin, and S. baicalensis ethanol extract also decreased the number of inflammatory cells especially eosinophils and downregulated peribronchial and perivascular inflammation in the lungs of mice challenged by OVA. Baicalein, wogonin, and S. baicalensis ethanol extract significantly reduced the levels of tumor necrosis factor α, interleukin (IL)-1β, IL-4, IL-5 and the production of OVA-specific IgE and IgG1, and upregulated the level of interferon-γ and OVA-specific IgG2a. In addition, oral administration of baicalein, wogonin, and S. baicalensis ethanol extract inhibited compound 48/80-induced systemic anaphylaxis and plasma histamine release in mice. Moreover, baicalein, wogonin, and S. baicalensis ethanol extract suppressed compound 48/80-induced mast cell degranulation and histamine release from rat peritoneal mast cells. Conclusively, baicalein and wogonin as major flavonoids of S. baicalensis may have therapeutic potential for allergic asthma through modulation of Th1/Th2 cytokine imbalance and histamine release from mast cells.

Abstract
MicroRNAs (miRNAs) have been reported to circulate in the blood in a highly stable and cell-free form. Dysregulated expression of miRNAs has been detected in various pathological conditions including atopic dermatitis. In our study, human blood plasma miRNAs were identified by high-throughput sequencing and compared among patients of atopic dermatitis and healthy controls. We found that miR-151a was differentially expressed in the plasma of atopic dermatitis patients. MiR-151a regulates the expression of IL12RB2 by targeting two loci in the 3' untranslated region of the Il12rb2 gene. Moreover, IL12RB2 was remarkably downregulated in Jurkat cells overexpressing miR-151a. Jurkat cells treated with phytohemagglutinin also showed reduced expression of IFN-γ, interleukin-2 (IL-2) and IL-12. Together, these results suggest that miR-151a is involved in the pathogenesis of atopic dermatitis by regulating IL12RB2.

Abstract
AIM OF THE STUDY MicroRNA-21 (miR-21) is up-regulated during allergic airway inflammation, reflecting a Th2 immune response. We investigated the effects of an miR-21 antagomir and its mechanism of action in a mouse model of acute bronchial asthma. MATERIALS AND METHODS BALB/c mice were sensitized and challenged with ovalbumin (OVA). The anti-miR-21 antagomir was administered by intranasal inhalation from the day of sensitization. Changes in cell counts, Th2 cytokine levels in bronchoalveolar (BAL) fluid, and airway hyper-responsiveness (AHR) were examined. Histopathological changes and expression levels of miR-21 in lung tissues were analyzed. The mechanism of action of the antagomir was investigated by counting CD4+/CD8- T cells in splenocytes and by measuring the expression levels of transcription factors associated with T cell polarization. RESULTS MiR-21 expression was selectively down-regulated in the lung tissues of mice treated with anti-miR-21. The antagomir suppressed AHR compared with that of the OVA-challenged and scrambled RNA-treated groups. It also reduced the total cell and eosinophil counts in BAL fluid and the levels of Th2 cytokines, including IL-4, IL-5, and IL-13. The direct target of miR-21, IL-12p35, was induced in the antagomir-treated group, decreasing the CD4+/CD8- T cell proportions in splenocytes. The levels of transcription factors involved in the Th2-signaling pathway were reduced in lung tissues on treatment with the antagomir. CONCLUSIONS The miR-21 antagomir suppresses the development of allergic airway inflammation in a mouse model of acute bronchial asthma, inhibiting Th2 activation. These results suggest that this antagomir might be useful for treating bronchial asthma.

Abstract
AIM OF THE STUDY To delineate the underlying mechanism of microRNA-145 modulate the balance of Th1/Th2 via targeting RUNX3 in asthma patients. MATERIALS AND METHODS Peripheral blood samples were collected from asthma patients and healthy controls. CD4+ T cells were isolated and cultured. Using quantitative PCR detect, the level of microRNA-145 and RUNX3 mRNA level in the CD4+ T cells from asthma patients and healthy controls, meanwhile, western blot was used to detect the RUNX3 protein level. Th1 or Th2 related cytokines were measured by enzyme-linked immunosorbent assay. Dual-Luciferase Reporter Assay was performed to confirm the correlation between microRNA-145 and RUNX3. MicroRNA-145 mimic or inhibitor was transfected in the CD4+ T cells and the changes of RUNX3 level, Th1 or Th2 related cytokines and the percentage of Th1 and Th2 were observed after transfection. RESULTS MicroRNA-145 level of CD4+ T cells was higher with a lower RUNX3 expression in asthma patients. There is negative correlation between microRNA-145 and RUNX3. Th2 hyperactivity and Th1 deficiency was detected in the CD4+ T cells of asthma patients. Dual-Luciferase Reporter Assay has shown that RUNX3 is a target of microRNA. Up-regulation or down-regulation of miR-145 level caused RUNX3 expression changes in CD4+ T cells and influence the related cytokines. Inhibition of microRNA-145 may reverse the imbalance of Th1/Th2 in asthma patients. CONCLUSION MicroRNA-145 could regulate the balance of Th1/Th2 through targeting the RUNX3 in asthma patients. MicroRNA-145 and RUNX3 may be used as biomarkers or targets in the diagnosis or therapy of asthma.

Mangiferin inhibits lipopolysaccharide-induced production of interleukin-6 in human oral epithelial cells by suppressing toll-like receptor signaling. Arch Oral Biol 2016; 71:155-161. [PMID: 27517515 DOI: 10.1016/j.archoralbio.2016.08.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2015] [Revised: 07/27/2016] [Accepted: 08/03/2016] [Indexed: 02/05/2023]
Abstract
OBJECTIVE Oral epithelial cells have currently been found to play an important role in inflammatory modulation in periodontitis. Mangiferin is a natural glucosylxanthone with anti-inflammatory activity. The aim of this study was to investigate the regulatory effect of mangiferin on lipopolysaccharide (LPS)-induced production of proinflammatory cytokine interleukin-6 (IL-6) in oral epithelial cells and the underlying mechanisms. DESIGN The levels of LPS-induced IL-6 production in OKF6/TERT-2 oral keratinocytes were detected using enzyme-linked immunosorbent assay (ELISA). The expression of Toll-like receptor (TLR) 2 and TLR4 was determined using western blot analysis. And the phosphorylation of TLR downstream nuclear factor-κB (NF-κB), p38 mitogen-activated protein kinase (p38 MAPK) and c-Jun N-terminal kinase (JNK) was examined using cell-based protein phosphorylation ELISA kits. RESULTS We found that mangiferin reduced LPS-upregulated IL-6 production in OKF6/TERT-2 cells. Additionally, mangiferin inhibited LPS-induced TLR2 and TLR4 overexpression, and suppressed the phosphorylation of NF-κB, p38 MAPK and JNK. Moreover, mangiferin repressed IL-6 production and TLR signaling activation in a dose-dependent manner after 24h treatment. CONCLUSIONS Mangiferin decreases LPS-induced production of IL-6 in human oral epithelial cells by suppressing TLR signaling, and this glucosylxanthone may have potential for the treatment of periodontitis.

Abstract
Polyphenols have been described to have a wide range of biological activities, and many reports, published during recent years, have highlighted the beneficial effects of phenolic compounds, illustrating their promising role as therapeutic tools in several acute and chronic disorders. The purpose of study was to evaluate, in an already-assessed model of lung injury caused by bleomycin (BLM) administration, the role of resveratrol and quercetin, as well as to explore the potential beneficial properties of a mango leaf extract, rich in mangiferin, and a grape leaf extract, rich in dihydroquercetin (DHQ), on the same model. Mice were subjected to intra-tracheal administration of BLM, and polyphenols were administered by oral route immediately after BLM instillation and daily for 7 d. Treatment with resveratrol, mangiferin, quercetin and DHQ inhibited oedema formation and body weight loss, as well as ameliorated polymorphonuclear infiltration into the lung tissue and reduced the number of inflammatory cells in bronchoalveolar lavage fluid. Moreover, polyphenols suppressed inducible nitric oxide synthase expression, and prevented oxidative and nitroxidative lung injury, as shown by the reduced nitrotyrosine and poly (ADP-ribose) polymerase levels. The degree of apoptosis, as evaluated by Bid and Bcl-2 balance, was also suppressed after polyphenol treatment. Finally, these natural products down-regulated cyclo-oxygenase-2, extracellular signal-regulated kinase phosphorylated expression and reduced NF-κBp65 translocation. Our findings confirmed the anti-inflammatory effects of resveratrol and quercetin in BLM-induced lung damage, and highlight, for the first time, the protective properties of exogenous administration of mangiferin and DHQ on experimental pulmonary fibrosis.

Abstract
In recent years, T helper (Th) 9 cells have been demonstrated to be key mediators in immune responses in asthmatic lungs, and innate lymphoid cells 2 (ILC2s) have been described as a novel type of innate immunocyte with the ability to enhance immunoglobulin E (IgE) production. However, the interaction between ILC2s and Th9 cells in the pulmonary system of a mouse model of asthma remains to be elucidated. In the present study, the response state of lung tissue with regards to Th9 and ILC2s in a mouse model of asthma was investigated by detecting Th9‑ and ILC2‑associated cytokine receptors. The present study also investigated the association between the expression levels of the cytokine receptors in lung tissue samples and the IgE levels in sera samples from mouse models of asthma. Results from the present study demonstrated that the frequency of ILC2s and Th9 cells was significantly increased in the lung tissue samples, indicating that a Th2-type immune response had occurred. In addition, high mRNA expression levels of RAR‑related orphan receptor α, interleukin 1 receptor‑like 1, transcription factor PU.1 and interleukin (IL)‑9 were observed. Furthermore, IL‑5Rα, IL‑13Rα2 and high‑affinity IgE receptor were increased in mouse models of asthma, and a positive association was observed between the expression levels of ILC2‑ or Th9‑associated receptors in tissue samples and IgE levels in the sera. This indicated that ILC2s and Th9 were in a state of polarization and may promote each other in the lung tissue of mouse models of asthma, and that the lung tissue was responding to the two types of cells via increased expression of receptors.
