The potential application and molecular mechanisms of natural products in the treatment of allergic rhinitis: A review. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 129:155663. [PMID: 38759345 DOI: 10.1016/j.phymed.2024.155663] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 03/21/2024] [Accepted: 04/20/2024] [Indexed: 05/19/2024]
Abstract
BACKGROUNDS Allergic rhinitis (AR) is a non-infectious chronic inflammation of the nasal mucosa mainly mediated by immunoglobulin E (IgE) in atopic individuals after exposure to allergens. The application of AR guideline-recommended pharmacotherapies can rapidly relieve symptoms of AR but with poor long-term efficacy, and many of these therapies have side effects. Many natural products and their derivatives have shown potential therapeutic effects on AR with fewer side effects. OBJECTIVES This review aims to expand understanding of the roles and mechanisms of natural compounds in the treatment of AR and to highlight the importance of utilizing natural products in the treatment of AR. MATERIAL AND METHOD We conducted a systematic literature search using PubMed, Web of Science, Google Scholar, and Clinical Trials. The search was performed using keywords including natural products, natural compounds, bioproducts, plant extracts, naturally derived products, natural resources, allergic rhinitis, hay fever, pollinosis, nasal allergy. Comprehensive research and compilation of existing literature were conducted. RESULTS This article provided a comprehensive review of the potential therapeutic effects and mechanisms of natural compounds in the treatment of AR. We emphasized that natural products primarily exert their effects by modulating signalling pathways such as NF-κB, MAPKs, STAT3/ROR-γt/Foxp3, and GATA3/T-bet, thereby inhibiting the activation and expansion of allergic inflammation. We also discussed their toxicity and clinical applications in AR therapy. CONCLUSION Taken together, natural products exhibit great potential in the treatment of AR. This review is also expected to facilitate the application of natural products as candidates for treating AR. Furthermore, drug discovery based on natural products has a promising prospect in AR treatment.

Abstract
In light of the constantly increasing prevalence of allergic diseases, changes in dietary patterns have been suggested as a plausible environmental explanation for the development and progression of these diseases. Nowadays, much attention has been paid to the development of dietary interventions using natural substances with anti-allergy activities. In this respect, dietary polyphenols have been studied extensively as one of the most prominent natural bioactive compounds with well-documented anti-inflammatory, antioxidant, and immunomodulatory properties. This review aims to discuss the mechanisms underlying the potential anti-allergic actions of polyphenols related to their ability to reduce protein allergenicity, regulate immune response, and gut microbiome modification; however, these issues need to be elucidated in detail. This paper reviews the current evidence from experimental and clinical studies confirming that various polyphenols such as quercetin, curcumin, resveratrol, catechins, and many others could attenuate allergic inflammation, alleviate the symptoms of food allergy, asthma, and allergic rhinitis, and prevent the development of allergic immune response. Conclusively, dietary polyphenols are endowed with great anti-allergic potential and therefore could be used either for preventive approaches or therapeutic interventions in relation to allergic diseases. Limitations in studying and widespread use of polyphenols as well as future research directions are also discussed.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 114:154777. [PMID: 37018850 DOI: 10.1016/j.phymed.2023.154777] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 03/05/2023] [Accepted: 03/16/2023] [Indexed: 06/19/2023]
Abstract
BACKGROUND AND PURPOSE The pathological progression of lung injury (LI) to idiopathic pulmonary fibrosis (IPF) is a common feature of the development of lung disease. At present, effective strategies for preventing this progression are unavailable. Baicalin has been reported to specifically inhibit the progression of LI to IPF. Therefore, this meta-analysis aimed to assess its clinical application and its potential as a therapeutic drug for lung disease based on integrative analysis. METHODS We systematically searched preclinical articles in eight databases and reviewed them subjectively. The CAMARADES scoring system was used to assess the degree of bias and quality of evidence, whereas the STATA software (version 16.0 software) was used for statistical analysis, including a 3D analysis of the effects of dosage frequency of baicalin in LI and IPF. The protocol of this meta-analysis is documented in the PROSPERO database (CRD42022356152). RESULTS A total of 23 studies and 412 rodents were included after several rounds of screening. Baicalin was found to reduce the levels of TNF-α, IL-1β, IL-6, HYP, TGF-β and MDA and the W/D ratio and increase the levels of SOD. Histopathological analysis of lung tissue validated the regulatory effects of baicalin, and the 3D analysis of dosage frequency revealed that the effective dose of baicalin is 10-200 mg/kg. Mechanistically, baicalin can prevent the progression of LI to IPF by modulating p-Akt, p-NF-κB-p65 and Bcl-2-Bax-caspase-3 signalling. Additionally, baicalin is involved in signalling pathways closely related to anti-apoptotic activity and regulation of lung tissue and immune cells. CONCLUSION Baicalin at the dose of 10-200 mg/kg exerts protective effects against the progression of LI to IPF through anti-inflammatory and anti-apoptotic pathways.

Abstract
Menopause-associated asthma impacts a subset of women, tends to be more severe, and is less responsive to current treatments. We recently developed a model of menopause-associated asthma using 4-Vinylcyclohexene Diepoxide (VCD) and house dust mites (HDM). The goal of this study was to uncover potential biomarkers and drivers of menopause-onset asthma by assessing serum and bronchoalveolar lavage fluid (BALF) samples from mice with and without menopause and HDM challenge by large-scale targeted metabolomics. Female mice were treated with VCD/HDM to model menopause-associated asthma, and serum and BALF samples were processed for large-scale targeted metabolomic assessment. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to examine metabolites of potential biological significance. We identified over 50 individual metabolites, impacting 46 metabolic pathways, in the serum and BALF that were significantly different across the four study groups. In particular, glutamate, GABA, phosphocreatine, and pyroglutamic acid, which are involved in glutamate/glutamine, glutathione, and arginine and proline metabolisms, were significantly impacted in the menopausal HDM-challenged mice. Additionally, several metabolites had significant correlations with total airway resistance including glutamic acid, histamine, uridine, cytosine, cytidine, and acetamide. Using metabolic profiling, we identified metabolites and metabolic pathways that may aid in discriminating potential biomarkers for and drivers of menopause-associated asthma.

Food Sci Nutr 2022; 11:972-982. [PMID: 36789047 PMCID: PMC9922124 DOI: 10.1002/fsn3.3132] [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: 04/29/2022] [Revised: 09/29/2022] [Accepted: 10/25/2022] [Indexed: 11/16/2022] Open
Abstract
Due to the high prevalence of allergies and asthma, awareness about allergens and therapeutic use of functional foods and nutraceuticals have gained immense attention. Spirulina powder is being used as health-boosting and antioxidant agent against several ailments owing to its unique nutritional profile. Considering its antioxidant role, the current study was focused on exploring therapeutic role of spirulina against stress biomarkers in asthmatic model. To assess the therapeutic efficacy of spirulina against allergic asthma-specific oxidative stress biomarkers, a model feed trial was conducted and rats were divided into four groups (n = 10). G0-I (negative control), G0-II (positive control), whereas GI (spirulina) and G2 (salbutamol) served as treatment groups. Salbutamol is a chemical compound which is used in several antiallergic medicines because it works as bronchodilator. G2 group was given salbutamol for comparison of results. For asthma induction, rats were given intraperitoneal injection of ovalbumin on 7th, 14th, and 21st day. Treatment groups were given spirulina powder (500 mg/kg body weight) and salbutamol (1 mg/kg), respectively, after the induction of asthma. All three asthmatic groups were also exposed to cigarette smoke daily along with respective treatment for 4 weeks. Asthma induction caused an increase in total cell count in bronchioalveolar fluid (BALF), while spirulina treatment reduced total cells in BALF by 33.50% and salbutamol by 41.7%. Level of interleukins (IL) like IL-4 decreased by 33.32% & 48.56% in G1 and G2. Similarly, IL-5 and IL-13 levels reduced by 40.9% & 49.9% and 18.62% & 38.02%, respectively, in G1 and G2. Serum levels of Immunoglobin-E (Ig-E) declined by 29.70% and 52.82%, while histamine levels were 26.23% & 45.58% less at the end of study in comparison to positive control. Moreover, histological analysis of lung tissue revealed that both spirulina and salbutamol effectively reduced ovalbumin and cigarette smoke-induced moderate to severe necrosis, architectural changes, and congestion. It was concluded that salbutamol showed better results however, spirulina also effectively reduced mild to moderate allergic symptoms in dose-dependent manner. Nutraceutical and functional foods are considered helpful in mitigating oxidative stress-mediated health problems. Spirulina has its unique nutritional profile including phycobiliproteins, phytochemicals, and antioxidant vitamins which make it useful against several ailments. Considering its antioxidant role, current study was focused on exploring therapeutic efficacy of spirulina against stress biomarkers in asthmatic model. Outcomes of present research also demonstrated beneficial effect of spirulina in modulating allergic symptoms. In this regard, ancient concept of "medicine food homology" can be implemented and spirulina can be incorporated in food for additional benefits. However, further research regarding safety aspects is needed for its use in clinical practice for humans.

Abstract
OBJECTIVES Nigella sativa oil is known antiallergic and immunomodulatory effects. We aimed to compare this oil with mometasone furoate, a topical steroid, on a rat model in the prevention of allergic rhinitis symptoms. METHODS A total of 28 two-to-four-month-old Wistar Hannover rats weighing 250-350 g were randomly divided into four groups of seven, which included control, allergic rhinitis, mometasone furoate, and Nigella sativa oil groups. Loss of cilia, an increase of goblet cells, vascular proliferation, inflammatory cell count, eosinophil infiltration, and the degree of hypertrophy in chondrocytes were assessed by light microscopy. RESULTS The frequency of nasal scratching in the Nigella sativa oil group was found to be significantly lower compared with the allergic rhinitis group (p < 0.05). Typical inflammatory changes seen in allergic rhinitis were not detected in the Nigella sativa oil group. No inflammation was observed in 85.7% of both the healthy control group and the Nigella sativa oil group. In addition, no inflammation was observed in 71.4% of the mometasone furoate group, and this difference was found to be significant compared with the control group (p < 0.05). In addition, eosinophil infiltration, cilia loss, chondrocyte hypertrophy, vascular proliferation, and goblet cell increase were found to be significantly decreased in the mometazone furoate and Nigella sativa oil groups compared to the allergic rhinitis group (p < 0.05). CONCLUSION According to the findings obtained from this study, we found anti-inflammatory and anti-allergic effects of Nigella sativa oil as equally effective as mometasone furoate in the treatment of experimentaly generated allergic rhinitis.

Abstract
Objective Radiation-induced lung injury (RILI) is a common complication of radiotherapy for thoracic tumors. This study investigated the alleviating effect of baicalin (BA) on RILI and its possible mechanism. Methods RILI model was established by chest irradiation (IR) of C57BL/6 mice for 16 weeks. Different concentrations of BA were administered, and dexamethasone (DXM) was used as a positive control. Then, the lung pathological changes were observed by HE and Masson staining. The levels of TGF-β, TNF-α, IL-1β, IL-6, CysLT, LTC4, and LTE4 were measured by ELISA. The CysLT1 expression was detected by qPCR, immunohistochemistry, and western blot. Type II AEC cells were pretreated with LTD-4 to establish the RILI cell model and intervened with different concentrations of BA. Then, the collagen I protein level was measured by ELISA. The CysLT1 and α-SMA expression were detected by qPCR, immunofluorescence, and western blot. Results BA could effectively improve lung histopathological changes and pulmonary fibrosis. In vivo, BA could inhibit the levels of TGF-β, TNF-α, IL-1β, and IL-6 and reduce the levels of CysLT, LTC4, and LTE4. In vitro, different concentrations of LTD4 could reduce the viability of type II AEC cells, which could be reversed by the administration of different concentrations of BA. In addition, BA could reduce CysLT1 mRNA, as well as CysLT1 and α-SMA protein levels in vitro and in vivo. Conclusion BA attenuated lung inflammation and pulmonary fibrosis by inhibiting the CysLTs/CysLT1 pathway, thereby protecting against RILI.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Malignant ascites (MA) effusion is mainly caused by hepatocellular, ovarian, and breast cancer etc. It has been reported that Euphorbia kansui (EK), the root of Euphorbia kansui S.L.Liou ex S.B.Ho, possessing a therapeutic effect on MA. However, the clinical applications of EK are seriously restricted for its severe toxicity. Although studies demonstrated that vinegar-processing can reduce the toxicity and retain the water expelling effect of EK, its specific mechanism remains unknown. AIM OF THE STUDY This study aims to explore the underlying mechanisms of toxicity reduction without compromising the pharmacological effects of EK stir-fried with vinegar (VEK). MATERIALS AND METHODS 3-O-(2'E,4'Z-decadienoyl)-20-O-acetylingenol (3-O-EZ), a major diterpenoid of EK, could convert into ingenol after processing EK with vinegar. The H22 mouse hepatoma ascites model was replicated, and were given 3-O-EZ and ingenol seven days (110.14, 50.07 and 27.54 mg/kg). The histopathological observation, serum liver enzymes, serum Renin-Angiotensin-Aldosterone System (RAAS) levels, ascites volumes, pro-inflammatory cytokines levels and H22 cells apoptosis in ascites were examined. Then the intestine (Aquaporin 8, AQP8) and kidney (Aquaporin 2, AQP2; Vasopressin type 2 receptor, V2R) protein expression were detected, as well as the metabolomics of serum were analyzed. Finally, the content of 3-O-EZ and ingenol in EK and VEK were investigated. RESULTS 3-O-EZ and ingenol can relieve hepatic and gastrointestinal injuries, reduce ascites volumes, enhance the H22 cells apoptosis, ameliorate abnormal pro-inflammatory cytokines and RAAS levels, and down-regulate the expression of AQP8, AQP2, V2R. The involved metabolic pathways mainly included glycerophospholipid metabolism and arachidonic acid metabolism. And the decreasing rate of 3-O-EZ in VEK was 19.14%, the increasing rate of ingenol in VEK was 92.31%. CONCLUSION 3-O-EZ and ingenol possess significant effect in treating MA effusion, while ingenol has lower toxicity compared with 3-O-EZ. And provide evidence for the mechanism of attenuation in toxicity without compromising the pharmacological effects of VEK.

Abstract
OBJECTIVE Rhinosinusitis is a global health problem affecting millions of people around the world. Baicalin is a bioactive compound isolated from medicinal plant Scutellaria baicalensis Georgi. The present study aims to investigate potential effects of baicalin on clinicopathological changes in nasal/sinus mucosa in a mouse model. METHODS A mouse model of sinonasal inflammation induced by high dose of ovalbumin was applied to evaluate effects of baicalin. Rhinosinusitis symptoms, histopathological features, levels of histamine, immunoglobulin E (IgE), IL-17A, IL-10, and balance of regulatory T cell (Treg)/T-helper 17 (Th17) responses were examined. RESULTS Baicalin significantly relieved rhinosinusitis symptoms in mice, reduced histopathological changes, and suppressed serum levels of histamine and IgE in a dose-dependent manner. In lymphocytes of mice, baicalin modulated balance of Treg/Th17 proportions by attenuating Th17 cells and enhancing Treg cells, respectively. The serum IL-17A was decreased and IL-10 was increased in mice treated by baicalin. In addition, baicalin promoted levels of Smad protein 3 (p-Smad3) and forkhead box P3 (FOXP3) to promote Treg cells while suppressed levels of p-Stat3 and retineic-acid-receptor-related orphan nuclear receptor γt (RORγt) to inhibit Th17 cells. CONCLUSIONS These data demonstrate that baicalin effectively ameliorates sinonasal inflammation in a mouse model by recovering the immunological balance of Treg/Th17 responses. Our finding highlights the potential value of baicalin for the treatment of rhinosinusitis.

Abstract
BACKGROUND Baicalin has many biological properties such as anti-oxidation and anti-allergy. The current study aimed to explore the effect of Baicalin on allergic rhinitis (AR) and its potential mechanism of action. METHODS Peripheral blood mononuclear cells (PBMCs) were isolated by density gradient centrifugation. Expression levels of Th17 and Treg cells-related proteins in nasal mucosa and peripheral blood cells were detected by real-time quantitative PCR, flow cytometry and Western blot. The mice were randomly divided into Control, ovalbumin (OVA), l-Baicalin, H-Baicalin, DSGC, 3-MA, and H-Baicalin + Rapa groups. Changes of allergic rhinitis conditions and eosinophil infiltration of the mice were detected and scored by Diff-Quik staining, and histological changes were observed by Hematoxylin & Eosin (H&E) staining and Periodate Schiff (PAS) staining. Serological changes, expression levels of interleukin-17A (IL-17A), interleukin-10 (IL-10), eosinophilic cationic protein (ECP) and anti-OVA-specific antibodies were detected by Enzyme-linked immunosorbent assay (ELISA). RESULTS Clinical case analysis found that AR patients had a Th17/Treg imbalance and activated autophagy, however, Baicalin restored Th17/Treg cell balance and inhibited autophagy in vitro. in vivo experiments demonstrated that Baicalin inhibited OVA-induced allergic nasal symptoms and the activation of autophagy pathway, which was the same as the regulation of 3-MA, while Rapa could weaken the effects of H-baicalin. Moreover, Baicalin reduced the infiltration of different inflammatory cells of the nasal lavage fluid, prevented the damages to epithelial cells, and improved nasal mucosal thickness and mucus secretion. In addition, Baicalin regulated the balance of mouse anti-OVA-specific antibody levels and expressions of Th17/Treg-associated cytokines. CONCLUSION Our study revealed that Baicalin can be used to treat AR, and the effect is realized through inhibiting autophagy to regulate Th17/Treg cell differentiation.

Clinical Efficacy Evaluation of 1-Year Subcutaneous Immunotherapy for Artemisia sieversiana Pollen Allergic Rhinitis by Serum Metabolomics. Front Pharmacol 2020; 11:305. [PMID: 32256368 PMCID: PMC7093654 DOI: 10.3389/fphar.2020.00305] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2019] [Accepted: 02/28/2020] [Indexed: 12/19/2022] Open
Abstract
Subcutaneous immunotherapy is the only treatment that improves the natural progression of allergic rhinitis and maintains long-term outcomes after discontinuation of the drug. Metabolomics is increasingly applied in the study of allergic diseases, including allergic rhinitis. However, little is known about the discovery of metabolites that can evaluate clinical efficacy and possible mechanisms of Artemisia sieversiana pollen subcutaneous immunotherapy. Thirty-three patients with Artemisia sieversiana pollen allergic rhinitis significantly improved after 1-year subcutaneous immunotherapy treatment, while ten patients were ineffective. Pre- and post-treatment serum samples from these patients were analyzed by metabolomics based on the combined detection of liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry. As a result, L-Tyrosine can be a potential biomarker because of its opposite trend in effective patients and ineffective patients. And mechanism of immunotherapy may be closely related to NO and nitric oxide synthase. The discovery of potential biomarkers and metabolic pathways has contributed to the in-depth study of mechanisms of subcutaneous immunotherapy treatment of Artemisia sieversiana pollen allergic rhinitis.

Abstract
This study was conducted to investigate the hypotensive effect of egg white
protein (EWP) hydrolysate (EWH) in spontaneously hypertensive rats (SHRs). The
hydrolysis of EWP was effectively performed with a combination of 0.5% bromelain
and 1% papain at 50°C for 60 min. The resulting hydrolysate did not
elicit an allergic reaction as confirmed by human mast cell activation test. The
systolic and diastolic blood pressures of the SHRs fed the EWH diet were
observed to be significantly or numerically lower than those of the other groups
during the experimental period of 28 d. EWH treatment significantly
(p<0.05) upregulated the nitric oxide levels in hCMEC/D3 cells and the
plasma of the SHRs compared to those in the control. Moreover, EWH ingestion
significantly (p<0.01) reduced the plasma angiotensin II level of the
SHRs compared with that in the control. In conclusion, beyond its basic
nutritional value, EWH prevents and manages hypertension, and thus can be an
invaluable resource for functional food development.
