Abstract
OBJECTIVES Asthma is a heterogeneous disease characterized by chronic airway inflammation. Huashanshen dripping pills (HSS) are commonly utilized for relieving asthma, relieving cough, and expelling phlegm. At present, the molecular mechanism against airway inflammation remains unclear. METHODS In this study, network pharmacology, molecular docking technology, and molecular dynamic simulation were used to predict the therapeutic pathways of HSS for asthma. The ovalbumin-induced mouse model was used to further validate the prediction by RT-qPCR, western blot, immunofluorescence, and related methods. KEY FINDINGS The findings indicate that HSS improves lung function and relieves lung inflammation by reducing inflammatory cell infiltration around the bronchus and reducing eosinophilic counts in bronchoalveolar lavage fluid (BALF). In addition, it lowers the levels of inflammatory cytokines and the expression levels of interleukin-4, interleukin-5, and interleukin-13 mRNA. HSS also inhibits the phosphorylation and nuclear translocation of NF-κB p65 protein. CONCLUSIONS All results suggested that HSS can decrease airway inflammation in asthmatic mice by inhibiting NF-κB signaling pathway. This finding will shed light on how it can be used to treat asthma.

High humidity and NO 2 co-exposure exacerbates allergic asthma by increasing oxidative stress, inflammatory and TRP protein expressions in lung tissue. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 353:124127. [PMID: 38759746 DOI: 10.1016/j.envpol.2024.124127] [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: 01/22/2024] [Revised: 04/04/2024] [Accepted: 05/07/2024] [Indexed: 05/19/2024]
Abstract
Allergic asthma is a chronic inflammatory airway disease with a high mortality rate and a rapidly increasing prevalence in recent decades that is closely linked to environmental change. Previous research found that high humidity (HH) and the traffic-related air pollutant NO2 both aggregated allergic asthma. Their combined effect and mechanisms on asthma exacerbation, however, are unknown. Our study aims to toxicologically clarify the role of HH (90%) and NO2 (5 ppm) on allergic asthma. Ninety male Balb/c mice were randomly assigned to one of six groups (n = 15 in each): saline control, ovalbumin (OVA)-sensitized, OVA + HH, OVA + NO2, OVA + HH + NO2, and OVA + HH + NO2+Capsazepine (CZP). After 38 days of treatment, the airway function, pathological changes in lung tissue, blood inflammatory cells, and oxidative stress and inflammatory biomarkers were comprehensively assessed. Co-exposure to HH and NO2 exacerbated histopathological changes and airway hyperresponsiveness, increased IgE, oxidative stress markers malonaldehyde (MDA) and allergic asthma-related inflammation markers (IL-1β, TNF-α and IL-17), and upregulated the expressions of the transient receptor potential (TRP) ion channels (TRPA1, TRPV1 and TRPV4). Our findings show that co-exposure to HH and NO2 disrupted the Th1/Th2 immune balance, promoting allergic airway inflammation and asthma susceptibility, and increasing TRPV1 expression, whereas CZP reduced TRPV1 expression and alleviated allergic asthma symptoms. Thus, therapeutic treatments that target the TRPV1 ion channel have the potential to effectively manage allergic asthma.

Aging (Albany NY) 2024; 16:6478-6487. [PMID: 38579176 PMCID: PMC11042943 DOI: 10.18632/aging.205716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 01/08/2024] [Indexed: 04/07/2024]
Abstract
Stigmasterol is a common dietary phytosterol with high nutritional value and physiological activity. In this study, we evaluated the effects of stigmasterol on inflammatory cytokines and the TGF-β1/Smad2 and IL-17A signaling pathway in an ovalbumin (OVA)-induced asthma mouse model. Stigmasterol treatment improved airway remodeling. In addition, it significantly attenuated the symptoms of asthma attacks, reduced the number of macrophages, lymphocytes, neutrophils, and eosinophils in BALF and inflammatory cytokines, including IL-1β, IL-5, IL-6, and IL-13. It further decreased the level of IL-17A in BALF, serum and spleen. Spleen single-cell suspension analysis via flow cytometry showed that IL-17A level was consistent with the results obtained in BALF, serum and spleen. Stigmasterol decreased the protein expression levels of TGF-β, p-Smad2 and IL-17A in the spleen, by increasing the protein expression level of IL-10. After 24 h of co-culture of TGF-β, IL-6 and stigmasterol, the level of IL-17 in CD4+ T cell supernatant was lower relative to levels in the group without stigmasterol. Meanwhile, stigmasterol treatment attenuated the expression level of TGF- β, p-Smad2 and IL-17A proteins in CD4+ T cells and enhanced the expression levels of IL-10 protein. These data suggested that stigmasterol inhibited the TGF-β1/Smad2 and IL-17A signaling pathway to achieve anti-asthmatic effects in the OVA-induced asthma mouse model. Collectively, the results of this study are that stigmasterol has achieved preliminary efficacy in the non-clinical laboratory, further studies are needed to consider the clinical application of stigmasterol.

Abstract
NF-κB signaling has been discovered for nearly 40 years. Initially, NF-κB signaling was identified as a pivotal pathway in mediating inflammatory responses. However, with extensive and in-depth investigations, researchers have discovered that its role can be expanded to a variety of signaling mechanisms, biological processes, human diseases, and treatment options. In this review, we first scrutinize the research process of NF-κB signaling, and summarize the composition, activation, and regulatory mechanism of NF-κB signaling. We investigate the interaction of NF-κB signaling with other important pathways, including PI3K/AKT, MAPK, JAK-STAT, TGF-β, Wnt, Notch, Hedgehog, and TLR signaling. The physiological and pathological states of NF-κB signaling, as well as its intricate involvement in inflammation, immune regulation, and tumor microenvironment, are also explicated. Additionally, we illustrate how NF-κB signaling is involved in a variety of human diseases, including cancers, inflammatory and autoimmune diseases, cardiovascular diseases, metabolic diseases, neurological diseases, and COVID-19. Further, we discuss the therapeutic approaches targeting NF-κB signaling, including IKK inhibitors, monoclonal antibodies, proteasome inhibitors, nuclear translocation inhibitors, DNA binding inhibitors, TKIs, non-coding RNAs, immunotherapy, and CAR-T. Finally, we provide an outlook for research in the field of NF-κB signaling. We hope to present a stereoscopic, comprehensive NF-κB signaling that will inform future research and clinical practice.

Abstract
Asthma is a chronic pulmonary disease with marked infiltrating inflammatory cells and reduced respiratory performance. Echinochrome (Ech) is a dark-red pigment isolated from the sea urchin spines, shells, and ova. It has antioxidant, antimicrobial, and anti-inflammatory properties, but whether it can be used in asthma treatment has yet to be investigated. In this research, we aimed to study the inhibitory actions of Ech on allergic asthma symptoms in mice. Mice were divided into 4 groups (n = 8 for each): control, ovalbumin-challenged, and Ech-treated (0.1 and 1 mg/kg). At the end of the experiment, nasal scratching, lung oxidative stress, airway inflammation, and remodeling were assessed. In ovalbumin-challenged BALB/C mice, treatment with Ech significantly decreased nasal scratching, lung oxidative stress, inflammatory cell infiltration, mucus hyperproduction and hyperplasia of goblet cells, IgE levels, and inflammatory cytokines. It also inhibited NF-κB phosphorylation. This is the first study to investigate the immunomodulatory effect of Ech against allergic asthma in mice. According to our findings, we imply that Ech may be utilized as a treatment for allergic asthma.

Abstract
BACKGROUND Allergic rhinitis (AR) is the most prevalent form of atopic disease. Undaria pinnatifida has potent antioxidative, antidiabetic, and anti-inflammatory properties. AIMS We investigated the immunomodulatory effect of Undaria pinnatifida extract (UPE) on allergic inflammation in an AR mouse model. MATERIALS & METHODS Mice were sensitized and intranasally challenged with ovalbumin (OVA), and the Th1/Th2 and Th17/Treg-related cytokines and histopathology were exanimated after UPE treatments. Enzyme-linked immunosorbent assay was performed using serum samples and NALF to detect OVA-specific immunoglobulins and inflammatory cytokines. Mitogen-activated protein kinases (MAPKs) were measured by western blotting analysis, and an in vitro study measured mast cell activation induced by compound 48/80. RESULTS After UPE treatment, nasal and lung allergy symptoms, nasal mucosal swelling, and goblet cell hyperplasia were ameliorated. Oral UPE regulated the balance of Th1/Th2 and Th17/Treg cell differentiation in AR mice in a dose-dependent manner. In addition, UPE attenuated the migration of eosinophils and mast cells to the nasal mucosa by suppressing nuclear factor kappa B (NF-κB)/MAPKs. The levels of anti-OVA IgE and IgG1 were also decreased. DISCUSSION UPE inhibited inflammation by regulating the NF-κB/MAPKs signaling pathway and supressing the activation of critical immune cells such as eosinophils and mast cells. CONCLUSION UPE may have therapeutic potential for AR.

Abstract
BACKGROUND AND OBJECTIVE Colorectal cancer (CRC) is a neoplastic disease that gradually develops due to genetic variations and epigenetic changes. Surgical excision is the first-line treatment for CRC. Accumulating evidence has shown that total intravenous anesthesia has beneficial effects for CRC patients as it decreases the probability of tumor recurrence and metastasis. Propofol is one of the most frequently used intravenous anesthetics in clinical practice. However, it remains unknown whether it can reduce recurrence and metastasis after surgery in cancer patients. METHODS CRC cell lines (HCT116 and SW480) were cultured in vitro, and different concentrations of propofol were added to the cell culture medium. The proliferation effect of propofol on CRC cell lines was evaluated by CCK-8 assay. The effect of propofol on the migration and invasion of CRC cells was evaluated by scratch healing and Transwell experiments. The inhibitory effects of propofol on NF-κB and HIF-1α expressions in CRC cell lines were determined by Western blotting and immunofluorescence assays to further clarify the regulatory effects of propofol on NF-κB and HIF-1α. RESULTS Compared to the control, propofol significantly inhibited the proliferation, migration, and invasion abilities of CRC cells (HCT116 and SW480) (p < 0.0001). The expression levels of NF-κB and HIF-1α gradually decreased with increasing propofol concentration in both cell lines. After activation and inhibition of NF-κB, the expression of HIF-1α changed. Further studies showed that propofol inhibited LPS-activated NF-κB-induced expression of HIF-1α, similar to the NF-κB inhibitor Bay17083 (p < 0.0001). CONCLUSION In vitro, propofol inhibited the proliferation, migration, and invasion of CRC cells (HCT116 and SW480) in a dose-dependent manner, possibly by participating in the regulation of the NF-κB/HIF-1α signaling pathway.

Abstract
Asthma is a pulmonary disease induced by the inhalation of aeroallergens and subsequent inappropriate immune responses. Camellia sinensis (L.) Kuntze has been evaluated as an effective antioxidant supplement produced from bioactive compounds, including flavonoids. In this study, we aimed to determine the effects of Camellia sinensis (L.) Kuntze extract (CE) on ovalbumin-induced allergic asthma. The components of CE were analyzed using high-performance liquid chromatography (HPLC) chromatogram patterns, and asthmatic animal models were induced via ovalbumin treatment. The antioxidant and anti-inflammatory effects of CE were evaluated using 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH), 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS), and nitric oxide (NO) assays. Seven compounds were detected in the CE chromatogram. In the ovalbumin-induced mouse model, CE treatment significantly decreased the inflammation index in the lung tissue. CE also significantly decreased eosinophilia and the production of inflammatory cytokines and OVA-specific IgE in animals with asthma. Collectively, our results indicate that CE has anti-inflammatory and antioxidant activities, and that CE treatment suppresses asthmatic progression, including mucin accumulation, inflammation, and OVA-specific IgE production.

Echinochrome Ameliorates Physiological, Immunological, and Histopathological Alterations Induced by Ovalbumin in Asthmatic Mice by Modulating the Keap1/Nrf2 Signaling Pathway. Mar Drugs 2023; 21:455. [PMID: 37623736 PMCID: PMC10455754 DOI: 10.3390/md21080455] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 08/15/2023] [Accepted: 08/16/2023] [Indexed: 08/26/2023] Open
Abstract
Asthma is a persistent inflammatory disease of the bronchi characterized by oxidative stress, airway remodeling, and inflammation. Echinochrome (Ech) is a dark-red pigment with antioxidant and anti-inflammatory activities. In this research, we aimed to investigate the effects of Ech against asthma-induced inflammation, oxidative stress, and histopathological alterations in the spleen, liver, and kidney in mice. Mice were divided into four groups (n = 8 for each): control, asthmatic, and asthmatic mice treated intraperitoneally with 0.1 and 1 mg/kg of Ech. In vitro, findings confirmed the antioxidant and anti-inflammatory activities of Ech. Ech showed antiasthmatic effects by lowering the serum levels of immunoglobulin E (IgE), interleukin 4 (IL-4), and interleukin 1β (IL-1β). It attenuated oxidative stress by lowering malondialdehyde (MDA) and nitric oxide (NO) contents and increasing reduced glutathione (GSH), superoxide dismutase (SOD), glutathione-s-transferase (GST), and catalase (CAT) in the liver, spleen, and kidney. Moreover, it protected asthma-induced kidney and liver functions by increasing total protein and albumin and decreasing aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, urea, and uric acid levels. Additionally, it ameliorated histopathological abnormalities in the lung, liver, spleen, and kidney. Additionally, molecular docking studies were used to examine the interactions between Ech and Kelch-like ECH-associated protein 1 (Keap1). PCR and Western blot analyses confirmed the association of Ech with Keap1 and, consequently, the regulatory role of Ech in the Keap1-(nuclear factor erythroid 2-related factor 2) Nrf2 signaling pathway in the liver, spleen, and kidney. According to our findings, Ech prevented asthma and its complications in the spleen, liver, and kidney. Inhibition of inflammation and oxidative stress are two of echinochrome's therapeutic actions in managing asthma by modulating the Keap1/Nrf2 signaling pathway.

Attenuates the allergic airway inflammation of cold asthma via inhibiting the activation of TLR4-medicated NF-kB and NLRP3 signaling pathway. JOURNAL OF ETHNOPHARMACOLOGY 2023; 315:116720. [PMID: 37268256 DOI: 10.1016/j.jep.2023.116720] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 05/28/2023] [Accepted: 05/30/2023] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pinellia ternata (Thunb.) Breit. (PT) has been demonstrated to be effective against the allergic airway inflammation (AAI) in clinical practices, especially in cold asthma (CA). Until now, the active ingredients, protective effect, and possible mechanism of PT against CA remain unknown. AIM OF THE STUDY The aim of this investigation was to examine the therapeutic impact and elucidate the underlying mechanism of PT on the AAI of CA. METHODS The compositions of PT water extract were determined via the UPLC-Q-TOF-MS/MS. The ovalbumin (OVA) and cold-water baths were used to induce CA in female mice. Morphological characteristic observations, expectorant effect, bronchial hyperreactivity (BHR), excessive mucus secretion, and inflammatory factors were used to uncover the treatment effect of PT water extract. In addition, the mucin 5AC (MUC5AC) mRNA and protein levels and the aquaporin 5 (AQP5) mRNA and protein levels were detected via qRT-PCR, immunohistochemistry (IHC), and western blotting. Moreover, the protein expressions associated with the TLR4, NF-κB, and NLRP3 signaling pathway were monitored by western blot analysis. RESULTS Thirty-eight compounds were identified from PT water extract. PT showed significant therapeutic effects on mice with cold asthma in terms of expectorant activity, histopathological changes, airway inflammation, mucus secretion, and hyperreactivity. PT exhibited good anti-inflammatory effects in vitro and in vivo. The expression levels of MUC5AC mRNA and protein decreased significantly, while AQP5 expression levels increased significantly in the lung tissues of mice after administration with PT as compared to mice induced by CA. Furthermore, the protein expressions of TLR4, p-iκB, p-p65, IL-1β, IL-18, NLRP3, cleaved caspase-1, and ASC were markedly reduced following PT treatment. CONCLUSIONS PT attenuated the AAI of CA by modulating Th1- and Th2-type cytokines. PT could inhibit the TLR4-medicated NF-kB signaling pathway and activate the NLRP3 inflammasome to reduce CA. This study provides an alternative therapeutic agent of the AAI of CA after administration with PT.

Supplementation of syringic acid-rich Phrynium pubinerve leaves imparts protection against allergic inflammatory responses by downregulating iNOS, COX-2, and NF-κB expressions. Heliyon 2023; 9:e13343. [PMID: 36816283 PMCID: PMC9932742 DOI: 10.1016/j.heliyon.2023.e13343] [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: 06/18/2022] [Revised: 12/24/2022] [Accepted: 01/25/2023] [Indexed: 02/04/2023] Open
Abstract
Background The present study was designed to characterize the role of ethanolic leaf extract of Phrynium pubinerve Blume (EPP) supplement in attenuating allergic inflammation, encouraged by the presence of syringic acid in it, as this phenolic acid is reportedly promising in suppressing serum immunoglobulin E (IgE) and inflammatory cytokine levels. Materials and methods HPLC-DAD dereplication analysis was performed to determine the presence of the vital polyphenolic metabolites. The efficacy of EPP against lipopolysaccharide (LPS)-induced inflammation in RAW 264.7 cells was evaluated by measuring its inhibitory effects on NO and ROS/RNS production. The expressions of major inflammation-associated molecules (iNOS, COX-2, NF-κB, IL-6, and TNF-α) in RAW 264.7 cells were assessed through Western blot. Physiological and behavioral changes, BMI, and different biochemical parameters in mice blood serum were investigated in the toxicological assays. Formaldehyde-induced paw edema test in mice was conducted using established animal model. TDI-induced allergic model in mice was carried out to determine different allergy-like symptoms, and differential white blood cell (WBC) counts in blood and bronchoalveolar lavage (BAL) fluid. The intermolecular interaction analysis of the identified major metabolite of EPP with H1R and iNOS was studied by molecular docking. Results HPLC-DAD analysis showed the presence of syringic acid (89.19 mg/100 g EPP) and a few other compounds. LPS-induced NO generation was reduced by EPP in a concentration-dependent manner, showing IC50 of 28.20 ± 0.27 μg/mL. EPP exhibited a similar inhibitory effect on ROS/RNS production with IC50 of 29.47 ± 2.19 μg/mL. Western blotting revealed that EPP significantly downregulated the expressions of iNOS, COX-2, NF-κB, IL-6, and TNF-α in RAW 264.7 cells when challenged with LPS. The toxicological assays confirmed the dosage and organ-specific safety of EPP. In the formaldehyde-induced paw edema test, EPP caused a 66.41% reduction in mice paw volume at 500 mg/kg dose. It ameliorated TDI-induced allergy-like symptoms and decreased different inflammatory WBCs in mice's blood and BAL fluid in a dose-dependent manner. Finally, syringic acid demonstrated mentionable intermolecular binding affinity towards H1R (-6.6 Kcal/moL) and iNOS (-6.7 Kcal/moL). Conclusions Collectively, considerable scientific reasoning was obtained in favor of the suppressive potential of EPP against allergic inflammatory responses that are proposed to be exerted via the downregulation of iNOS, COX-2, and NF-κB expressions, H1R antagonism and suppression of cytokines, such as IL-6, and TNF-α.

Abstract
Asthma is characterized by airway inflammation and remodeling. 2-Undecanone (methyl nonyl ketone), a volatile organic compound originating from Houttuynia cordata, has the potential to ameliorate inflammatory diseases. This study aimed to explore potential benefits of 2-undecanone in asthma. 2-Undecanone (100, 200, or 400 mg/kg) was administered intragastrically to ovalbumin (OVA)-challenged BALB/c mice. Lung tissues were collected to observe histopathological changes, and bronchoalveolar lavage fluid (BALF) was collected for the detection of inflammatory cells and cytokine production. The results showed that 2-undecanone ameliorated OVA-induced pathologic changes of lungs, including reducing inflammatory cell infiltration, goblet cell hyperplasia, and airway smooth muscle thickness. The number of inflammatory cells and the levels of IL-4, IL-5, IL-13, and IgE in BALF were decreased by 2-undecanone in asthmatic mice. Furthermore, abnormal activation of NF-κB pathway in lung tissues of asthmatic mice was impeded by 2-undecanone. In vitro, 2-undecanone (12.5, 25, or 50 µM) suppressed platelet-derived growth factor-BB-induced proliferation and migration of primary airway smooth muscle cells (ASMCs), and inhibited the switching of ASMCs from contractile phenotype to synthetic phenotype. Consistently, 2-undecanone blocked NF-κB activation in ASMCs. Collectively, 2-undecanone relieves asthma through alleviating airway inflammation and remodeling, and this beneficial effect is achieved by inhibiting NF-κB pathway.

Abstract
Leonurine (Leo) is a natural alkaloid extracted from Herba leonuri, which has many biological activities. However, whether leonurine has a protective effect on asthma remains unknown. The purpose of this study was to investigate the protective effect of leonurine on asthma. We evaluated its therapeutic effect and related signal transduction in LPS-induced RAW264.7 cells and OVA-induced asthmatic mice. In addition, we used network pharmacology, molecular docking and molecular dynamics simulation to verify the experimental results. In LPS-induced RAW 264.7 cells, leonurine significantly reduced the production of TNF-α and IL-6, andinhibited the activation of p38 MAPK/NF-κB signaling pathway. In OVA-induced asthmatic mice, leonurine decreased the number of inflammatory cells in the bronchoalveolar lavage fluid (BALF), particularly neutrophils and eosinophils. Leonurine also reduced the contents of IL-4, IL-5, IL-13 in the BALF and OVA-IgE in the serum. Leonurine remarkly improved OVA-induced inflammatory cell infiltration and significantly inhibited mucus overproduction. In addition, leonurine inhibited the activation of p38 MAPK/NF-κB signaling pathway in the lung tissues of asthmatic mice. Network pharmacology suggested that p38 MAPKα was a potential target of leonurine in the treatment of asthma. Molecular docking and molecular dynamics simulations indicated that leonurine could stably bind to p38 MAPKα protein. In summary, leonurine attenuated asthma by regulating p38 MAPK/NF-κB signaling pathway.

Abstract
Abstract
Objectives
Epidemiological investigations show that long-term exposure to PM2.5 is directly related to asthma-like and other respiratory diseases. This study aims to further explore the pharmacological effect of Ephedra sinica polysaccharide (ESP) on lung injury caused by atmospheric PM2.5.
Methods
To achieve the aim, we explored the therapeutic effect of ESP on an aggravated asthma-like mouse induced by PM2.5 combined with ovalbumin (OVA), and explored mechanisms underlying the connection between gut microbiota and lung function.
Key findings
Preliminary results showed that ESP alleviated the symptoms of aggravated allergic asthma-like in mice; reduced the number of eosinophils in BALF; reduced the levels of serum Ig-E, IL-6, TNF-α, and IL-1β. Further qRT-PCR detected that ESP inhibited the NF-κB pathway. The final analysis detected by 16S rRNA and short chain fatty acid (SCFA) confirmed that ESP increased relative proportions of Bacteroides, Lactobacillus, Prevotella, Butyricicoccus and Paraprevotella, but decreased that of Enterococcus and Ruminococcus; increased acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, isovaleric acid, and isohexanic acid in the meanwhile.
Conclusions
The study showed that ESP has a potential for future therapeutical applications in the prevention and treatment of asthma-like disease induced by PM2.5 and OVA via regulation of gut microbiota and SCFA.

Protective Effects of Platycodin D3 on Airway Remodeling and Inflammation via Modulating MAPK/NF-κB Signaling Pathway in Asthma Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:1612829. [PMID: 35990822 PMCID: PMC9385299 DOI: 10.1155/2022/1612829] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 06/06/2022] [Accepted: 07/06/2022] [Indexed: 11/20/2022]
Abstract
Background Asthma is a disease with airway hyperresponsive and airway inflammation. Platycodin D is a triterpenoid saponin extracted from Platycodon grandiflorus root, which has various pharmacological activities. The study mainly explored the effects of platycodin D3 (PD3) in airway remodeling and inflammation of asthma. Methods The ovalbumin (OVA)-induced asthma mice were given PD3 (20 mg/kg, 40 mg/kg, and 80 mg/kg) in different groups. The asthma mice administrated with dexamethasone (DXM) were enrolled as the positive control group, and the normal control mice and asthma model mice separately received the same volume of saline. Mouse airway lung dynamic compliance (Cdyn) and total airway resistance (RL) were measured by the EMKA animal lung function analysis system. The inflammation factor levels were estimated by ELISA. Histopathological changes were tested by HE and PAS staining. The protein and phosphorylation levels of NF-κBp65, p38, ERK1/2, and JNK1/2 were detected by Western blot. Results In asthmatic mice, PD3 enhanced the airway Cdyn and decreased RL to improve the airway hyperreactivity and alleviated the pathological injury of lung tissues. In addition, PD3 could reduce the infiltration of inflammatory cells in BALF and suppress the levels of eotaxin, IL-4, IL-5, IL-13, IFN-γ, and IgE. Furthermore, PD3 treatment inhibited the phosphorylation of NF-κBp65, p38, ERK1/2, and JNK1/2 proteins in asthma mice. Conclusion PD3 treatment alleviated the airway remodeling and inflammation in asthmatic mice, which might be related to downregulating the phosphorylated proteins in the MAPK/NF-κB signaling pathway.

Abstract
Six-year-old red ginseng, which is processed from the whole ginseng root via steaming and drying, has been shown to have preventive effects such as antioxidative, anti-inflammatory, and immunomodulatory. In this study, we evaluated the therapeutic effects of Korean red ginseng (KRG) against ovalbumin (OVA)-induced allergic asthma and the underlying mechanisms involved. We injected 20 µg of OVA on days 0 and 14, and mice were challenged with aerosolized OVA via a nebulizer for 1 h on days 21, 22, and 23. KRG was administered at 100 and 300 mg/kg from days 18 to 23. The KRG-treated mice showed significant reductions in their airway hyperresponsiveness, production of reactive oxygen species (ROS), and the number of inflammatory cells compared with the OVA-treated mice. The levels of type 2 cytokines in the bronchoalveolar lavage fluid and expression of OVA-specific immunoglobulin E in the serum, which were elevated in the OVA group, were reduced in the KRG-treated groups. The pro-inflammatory factors, inducible nitric oxide synthase and nuclear factor kappa-light-chain-enhancer of activated B cells, were downregulated by the KRG administration in a dose-dependent manner. KRG effectively suppressed the inflammatory response by inhibiting ROS production. Our results suggest that KRG may have the potential to alleviate asthma.

Abstract
Neobavaisoflavone (NBIF), a monomolecular compound extracted from Psoralea corylifolia (Leguminosae), is commonly used in traditional Chinese medicine for multiple purposes. NBIF is known to exert anti-fungal and anti-tumor effects, and promote bone formation. Whether NBIF exhibits anti-allergic effects by regulating mast cell activation remains unclear. Therefore, we designed this study to investigate the anti-allergic effects of NBIF on IgE/Ag-induced mouse bone marrow-derived mast cells and ovalbumin-induced asthma, and the passive systemic anaphylaxis (PSA) reaction in mice. Our results showed that NBIF suppresses the production of leukotriene C4, prostaglandin D2 and inflammatory cytokines, and decreases the degranulation of BMMCs stimulated by IgE/Ag. A thorough investigation ascertained that NBIF suppresses the phosphorylation of mitogen-activated protein kinases, and represses the nuclear factor-κB-related signaling pathway. In addition, the oral administration of NBIF in mice inhibited the IgE-induced PSA reaction in a dose-dependent manner. Overall, we provide new insights into how NBIF regulates the IgE/Ag-mediated signaling pathways. Moreover, our investigation promotes the potential use of NBIF in treating allergy and asthma.

Abstract
We investigated the immune response mechanisms under systemic and local inflammation using mouse models whereby lipopolysaccharide (LPS) was administered intraperitoneally to induce systemic inflammation, and epicutaneous sensitization with ovalbumin was used to induce local inflammation. LPS increased the immune cell infiltration in the cardiac muscle near the aorta, alveoli, hepatic sinusoid, renal interstitium, and the submucosal layer of the duodenum. Similarly, ovalbumin increased the abundance of macrophages in the skin. Both LPS and ovalbumin induced NF-κB p65 and IκBα phosphorylation, as well as the expression of NF-κB target genes (TLR4, IL6, and TNFα). Additionally, both LPS and ovalbumin led to an increase in the absolute IL-1β, IL-6, and TNFα serum levels and cytokine-related janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) phosphorylation. Moreover, the activated JAK2/STAT3 signaling increased the number of Ki67-positive cells (proliferating cells) and development pathway target gene expression (regeneration) in the inflammation models. In conclusion, LPS and ovalbumin increase immune cell infiltration in tissues, NF-κB activation, cytokine levels in serum, cytokine-stimulated JAK2/STAT3 signaling, and tissue regeneration.

Int J Mol Sci 2022; 23:ijms23031582. [PMID: 35163503 PMCID: PMC8836136 DOI: 10.3390/ijms23031582] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 01/17/2022] [Accepted: 01/24/2022] [Indexed: 12/10/2022] Open
Abstract
To investigate the effect of eupatilin in asthma treatment, we evaluated its therapeutic effect and related signal transduction in OVA-induced asthmatic mice and LPS-stimulated RAW264.7 cells. The BALF was tested for changes in lung inflammatory cells. Th2 cytokines in the BALF and OVA-IgE in the serum were measured by ELISA. H&E and PAS staining were used to evaluate histopathological changes in mouse lungs. The key proteins NF-κB, MAPK, and Nrf2 in lung tissues were quantitatively analyzed by Western blotting. Finally, we evaluated the effect of eupatilin on cytokines and related protein expression in LPS-stimulated RAW 264.7 cells in vitro. In OVA-induced asthmatic mice, eupatilin reduced the numbers of inflammatory cells, especially neutrophils and eosinophils. Eupatilin also decreased the levels of IL-5, IL-13 in the BALF and OVA-IgE in the serum. Furthermore, eupatilin inhibited the activation of NF-κB and MAPK pathways and increased the expression of Nrf2 in OVA-induced asthmatic mice. In vitro, eupatilin significantly reduced LPS-stimulated NO, IL-6, and ROS production. Additionally, the NF-κB, MAPK, and Nrf2 protein expression in LPS-stimulated RAW264.7 cells was consistent with that in OVA-induced asthmatic lung tissues. In summary, eupatilin attenuated OVA-induced asthma by regulating NF-κB, MAPK, and Nrf2 signaling pathways. These results suggest the utility of eupatilin as an anti-inflammatory drug for asthma treatment.

Biomed Pharmacother 2021; 144:112322. [PMID: 34656059 DOI: 10.1016/j.biopha.2021.112322] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 09/26/2021] [Accepted: 10/08/2021] [Indexed: 12/31/2022] Open
Abstract
Alpinia officinarum (AO) has been traditionally used in Asia as an herbal medicine to treat inflammatory and internal diseases. However, the therapeutic effect of AO on atopic dermatitis (AD) is unclear. Therefore, we examined whether Alpinia officinarum water extract (AOWex) affects AD in vivo and in vitro. Oral administration of AOWex to NC/Nga mice with Dermatophagoies farina extract (DfE)-induced AD-like symptoms significantly reduced the severity of clinical dermatitis, epidermal thickness, and mast cell infiltration into the skin and ear tissue. Decreased total serum IgE, macrophage-derived chemokine (MDC), and regulated on activation, normal T-cell expressed and secreted (RANTES) levels were observed in DfE-induced NC/Nga mice in the AOWex-treated group. These effects were confirmed in vitro using HaCaT cells. Treatment with AOWex inhibited the expression of proinflammatory chemokines such as MDC, RANTES, IP-10 and I-TAC in interferon-γ and tumor necrosis factor-α-stimulated HaCaT cells. The anti-inflammatory effects of AOWex were due to its inhibitory action on MAPK phosphorylation (ERK and JNK), NF-κB, and STAT1. Furthermore, galangin, protocatechuic acid, and epicatechin from AOWex were identified as candidate anti-AD compounds. These results suggest that AOWex exerts therapeutic effects against AD by alleviating AD-like skin lesions, suppressing inflammatory mediators, and inhibiting major signaling molecules.

Propofol Pretreatment Prevents Oxygen-Glucose Deprivation/Reoxygenation (OGD/R)-induced Inflammation Through Nuclear Transcription Factor κB (NF-κB) Pathway in Neuroblastoma Cells. Curr Neurovasc Res 2021; 17:27-34. [PMID: 31880261 DOI: 10.2174/1567202617666191227110158] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2019] [Revised: 11/17/2019] [Accepted: 11/19/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND Inflammation is one of the causes of neuroblastoma progression. Propofol attenuates inflammation by repressing nuclear transcription factor κB (NF-κB) in different diseases. But its effect on oxygen-glucose deprivation/reoxygenation (OGD/R)-induced inflammation is not known. OBJECTIVE This study investigated the role and mechanism of action of propofol on OGD/Rinduced inflammation in mouse N2A neuroblastoma cells. METHODS MTT was performed on mouse neuroblastoma cells N2A to assess and select the maximum safe dose of propofol. Next, N2A cells were pretreated with propofol and then, exposed to the OGD condition for 3 h and reoxygenated for 6 h. The content of the inflammatory factors, interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α), in the medium was measured by ELISA, while their protein expression was detected by western blot and immunofluorescence. The protein expression of P65, p-P65, IKBα and p-IKBα belonging to the NF-κB pathway was also determined by western blot in N2A cells. To further confirm the mechanism of propofol on OGD/R-induced inflammation in mouse N2A cells, P65 was over-expressed and the above experiments were repeated. RESULTS Propofol did not affect cell viability of N2A cells even at the maximum concentration used (30 µM), thus, 30 µM of propofol was selected to perform our experiments. Besides, OGD/R induced inflammation and activation of NF-κB pathway with increased p-P65 and p-IKBα expression, and propofol pretreatment inhibited OGD/R induced inflammation and activation of NF-κB pathway in N2A cells. Over-expression of P56 abolished the effects of propofol on OGD/Rinduced inflammation and activation of NF-κB pathway in N2A cells. CONCLUSION Our work demonstrated for the first time that propofol pretreatment ameliorated OGD/R induced inflammation via NF-κB pathway modulation in mouse neuroblastoma N2A cells, indicating that propofol might be considered as a potential therapeutic approach to reduce inflammation in neuroblastoma.

Abstract
Background Asthma is a complex inflammatory disorder that plagues a large number of people. Schisandrin B is an active ingredient of the traditional Chinese herbal medicine Schisandra with various proven physiological activities such as anti-inflammatory and antioxidant activities. In this study, we explored the anti-inflammatory and antioxidant effects and provided the mechanistic insights into the activity of schisandrin B in a mouse model of ovalbumin- (OVA-) induced allergic asthma. Methods Male BALB/c mice were sensitized and challenged with OVA to induce asthma and treated with various doses (15 mg/kg, 30 mg/kg, and 60 mg/kg) of SCH to alleviate the features of allergic asthma, airway hyperresponsiveness, inflammatory response, OVA-specific immunoglobulin (Ig)E level, and pathological injury. Results Schisandrin B significantly attenuated the airway hyperresponsiveness induced by OVA. Moreover, schisandrin B administration suppressed inflammatory responses, reduced the level of IgE, and attenuated pathological injury. Mechanistically, schisandrin B treatment promoted the activation of nuclear erythroid 2-related factor 2 (Nrf2), but suppressed the stimulation of the NF-κB pathway caused by OVA. Conclusion Taken together, our study suggests that schisandrin B attenuates the features of asthmatic lungs by inhibiting the NF-κB pathway and activating the Nrf2 signaling pathway.

Abstract
Perilla frutescens (L.) Britton is a classic herbal plant used widely against asthma in China. But its mechanism of beneficial effect remains undermined. In the study, the antiallergic asthma effects of Perilla leaf extract (PLE) were investigated, and the underlying mechanism was also explored. Results showed that PLE treatment significantly attenuated airway inflammation in OVA-induced asthma mice, by ameliorating lung pathological changes, inhibiting recruitment of inflammatory cells in lung tissues and bronchoalveolar lavage fluid (BALF), decreasing the production of inflammatory cytokines in the BALF, and reducing the level of immunoglobulin in serum. PLE treatment suppressed inflammatory response in antigen-induced rat basophilic leukemia 2H3 (RBL-2H3) cells as well as in OVA-induced human peripheral blood mononuclear cells (PBMCs). Furthermore, PLE markedly inhibited the expression and phosphorylation of Syk, NF-κB, PKC, and cPLA2 both in vivo and in vitro. By cotreating with inhibitors (BAY61-3606, Rottlerin, BAY11-7082, and arachidonyl trifluoromethyl ketone) in vitro, results revealed that PLE's antiallergic inflammatory effects were associated with the inhibition of Syk and its downstream signals NF-κB, PKC, and cPLA2. Collectively, the present results suggested that PLE could attenuate allergic inflammation, and its mechanism might be partly mediated through inhibiting the Syk pathway.

Abstract
Asthma is an allergic chronic inflammatory disease of the pulmonary airways, characterized by the infiltration of white blood cells and release of inflammatory cytokines of complex pathways linked to its pathogenesis. Syringin extracted from various medicinal plants has been used extensively for the treatment of inflammatory diseases. Hence, this study was conducted to further explore the protective effects of the syringin in ovalbumin (OVA) induced-asthma mice model. OVA-sensitized BALB mice were treated intraperitonealy with three doses (25, 50 and 100 mg/kg) of the syringin which was validated by the alteration in the immunoglobulin E (IgE) levels, cytokines levels, histopathological evaluation inflammatory cell count, lung weight, nitrite (NO) levels, oxidative stress biomarkers and gene markers. The treatment of syringin intensely reduced the increased IgE, inflammatory cytokines, WBC count and restored the antioxidant stress markers OVA stimulated animals. In addition, a significant reduction in inflammation and mucus production was evidenced in histopathological analysis which was further validated by suppression NF-κB pathway activation by syringin. These results suggest that syringin may improve asthma symptoms in OVA-induced mice by modulating NF-κB pathway activation.

Abstract
Asthma is a chronic inflammatory disease that cannot be cured. Maresin 1 (MaR1) is a specific lipid synthesized by macrophages that exhibits powerful anti-inflammatory effects in various inflammatory diseases. The goal of this study was to evaluate the effect of MaR1 on allergic asthma using an ovalbumin- (OVA-) induced asthma model. Thirty BALB/c mice were randomly allocated to control, OVA, and MaR1 + OVA groups. Mice were sacrificed 24 hours after the end of the last challenge, and serum, bronchoalveolar lavage fluid (BALF), and lung tissue were collected for further analysis. Western blotting was used to measure the protein level of IκBα, the activation of the NF-κB signaling pathway, and the expression of NF-κB downstream inflammatory cytokines. Quantitative real-time polymerase chain reactions (qRT-PCRs) were used to evaluate the expression levels of COX-2 and ICAM-1 in lung tissues. We found that high doses of MaR1 were most effective in preventing OVA-induced inflammatory cell infiltration and excessive mucus production in lung tissue, reducing the number of inflammatory cells in the BALF and inhibiting the expression of serum or BALF-associated inflammatory factors. Furthermore, high-dose MaR1 treatment markedly suppressed the activation of the NF-κB signaling pathway, the degradation of IκBα, and the expression of inflammatory genes downstream of NF-κB, such as COX-2 and ICAM-1, in the OVA-induced asthma mouse model. Our findings indicate that MaR1 may play a critical role in OVA-induced asthma and may be therapeutically useful for the management of asthma.

Abstract
Alnus hirsuta (Spach) Rupr. (AH), a member of the Betulaceae family, is widely used in Eastern Asia of as a source of medicinal compounds for the treatment of hemorrhage, diarrhea, and alcoholism. In this study, we investigated the protective effects of a methanolic extract of AH branches against airway inflammation and mucus production in tumor necrosis factor (TNF)-α-stimulated NCI-H292 cells and in an ovalbumin (OVA)-challenged allergic asthma mouse model. Female BALB/c mice were injected with OVA (40 μg) and aluminum hydroxide (2 mg) on days 0 and 14 to induce allergic airway inflammation. The mice were then challenged with 1% OVA from days 21–23. Mice were treated with AH (50 and 100 mg/kg/day; 2% DMSO) or dexamethasone (positive control; 3 mg/kg/day) from days 18–23. AH treatment effectively attenuated airway resistance/hyperresponsiveness and reduced levels of T helper type 2 (Th2) cytokines, eotaxins, and number of inflammatory cells in bronchoalveolar lavage fluid, and immunoglobulin E in serums of OVA-challenged mice. In histological analysis, AH treatment significantly inhibited airway inflammation and mucus production in OVA-challenged mice. AH treatment downregulated the phosphorylation of I kappa B-alpha, p65 nuclear factor-kappa B (p65NF-κB), and mitogen-activated protein kinases with suppression of mucin 5AC (MUC5AC) in lung tissue. Moreover, AH treatment decreased the levels of pro-inflammatory cytokines and Th2 cytokines, as well as MUC5AC expression, and inhibited the phosphorylation of p65NF-κB in TNF-α-stimulated NCI-H292 cells. These results indicate that AH might represent a useful therapeutic agent for the treatment of allergic asthma.

Yeast Fermentate Prebiotic Ameliorates Allergic Asthma, Associating with Inhibiting Inflammation and Reducing Oxidative Stress Level through Suppressing Autophagy. Mediators Inflamm 2021; 2021:4080935.

Abstract
Methods Ovalbumin was used to induce allergic asthma following administration of YFP for one week in mice, to collect the lung tissues, bronchoalveolar lavage fluid (BLFA), and feces. The pathological state, tight-junction proteins, inflammatory and oxidative stress-associated biomarkers, and TLRs/NF-κB signaling pathway of the lung tissues were evaluated by HE staining, immunofluorescence, ELISA, and WB, separately. RT-PCR was used to test oxidative stress-associated genes. Leukocyte counts of BLFA and intestinal microbiota were also analyzed using a hemocytometer and 16S rDNA-sequencing, separately. Result YFP ameliorated the lung injury of the mouse asthma model by inhibiting peribronchial and perivascular infiltrations of eosinophils and increasing tight-junction protein expression. YFP inhibited the decrease in the number of BALF leukocytes and expression of inflammatory-related genes and reversed OVA-induced TLRs/NF-κB signaling pathway activation. YFP ameliorated the level of oxidative stress in the lung of the mouse asthma model by inhibiting MDA and promoting the protein level of GSH-PX, SOD, CAT, and oxidative-related genes. ATG5, Beclin1, and LC3BII/I were significantly upregulated in asthma mice, which were greatly suppressed by the introduction of YFP, indicating that YFP ameliorated the autophagy in the lung of the mouse asthma model. Lastly, the distribution of bacterial species was slightly changed by YFP in asthma mice, with a significant difference in the relative abundance of 6 major bacterial species between the asthma and YFP groups. Conclusion Our research showed that YFP might exert antiasthmatic effects by inhibiting airway allergic inflammation and oxidative stress level through suppressing autophagy.

Abstract
Asthma and rhinitis are complex, heterogeneous diseases characterized by chronic inflammation of the upper and lower airways. While genome-wide association studies (GWAS) have identified a number of susceptible loci and candidate genes associated with the pathogenesis of asthma and allergic rhinitis (AR), the risk-associated alleles account for only a very small percent of the genetic risk. In allergic airway and other complex diseases, it is thought that epigenetic modifications, including DNA methylation, histone modifications, and non-coding microRNAs, caused by complex interactions between the underlying genome and the environment may account for some of this "missing heritability" and may explain the high degree of plasticity in immune responses. In this chapter, we will focus on the current knowledge of classical epigenetic modifications, DNA methylation and histone modifications, and their potential role in asthma and AR. In particular, we will review epigenetic variations associated with maternal airway disease, demographics, environment, and non-specific associations. The role of specific genetic haplotypes in environmentally induced epigenetic changes are also discussed. A major limitation of many of the current studies of asthma epigenetics is that they evaluate epigenetic modifications in both allergic and non-allergic asthma, making it difficult to distinguish those epigenetic modifications that mediate allergic asthma from those that mediate non-allergic asthma. Additionally, most DNA methylation studies in asthma use peripheral or cord blood due to poor accessibility of airway cells or tissue. Unlike DNA sequences, epigenetic alterations are quite cell- and tissue-specific, and epigenetic changes found in airway tissue or cells may be discordant from that of circulating blood. These two confounding factors should be considered when reviewing epigenetic studies in allergic airway disease.

[PMID: 32397290 PMCID: PMC7248972 DOI: 10.3390/molecules25092206] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Revised: 05/04/2020] [Accepted: 05/06/2020] [Indexed: 12/20/2022] Open
Abstract
Exposure to particulate matter (PM) has been known to be one of the risk factors to cause allergic asthma, leading to development of respiratory disease. Banhahubak-tang tablet (BHT), a standardized Korean Medicine, is prescribed for neurasthenia, laryngopharyngitis and asthma. In this study, we investigated therapeutic effects of BHT on airway inflammation in ovalbumin (OVA) and PM smaller than 10 μm (PM10)-induced allergic asthma mice. To establish allergic asthma with airway hyper-responsiveness by PM10, BALB/c mice were sensitized and challenged with OVA and PM10, and orally administered BHT. Histological staining was performed to assess airway remodeling. Serum and bronchoalveolar lavage fluid (BALF) was collected for measuring immunoglobulin levels and counting inflammatory cells, respectively. Expression levels of Janus kinase 1 (JAK1)/signal transducer and activator of transcription 6 (STAT6), pro-inflammatory cytokines and type 2 T-helper (Th2)-related cytokines were analyzed in vivo and in vitro models. Histopathological analysis demonstrated that BHT suppressed inflammatory cell infiltration, mucus hypersecretion and collagen deposition in the airway. BHT administration effectively decreased number of inflammatory cells in BALF. BHT reduced total serum Immunoglobulin E (IgE) and Immunoglobulin G (IgG) levels. In addition, BHT significantly inhibited the phosphorylation of JAK1 and STAT6 expressions. Release of pro-inflammatory cytokines and Th2-related cytokines were down-regulated by BHT. In conclusion, BHT mitigated airway inflammation by down-regulating pro-inflammatory and Th2-related cytokines via JAK1/STAT6 signaling. BHT might be a promising herbal medicine for preventing airway inflammation. Moreover, an intervention study among humans is needed to further evaluate the possible beneficial effects of BHT in allergic asthma.

Propofol Attenuates Hypoxia-Induced Inflammation in BV2 Microglia by Inhibiting Oxidative Stress and NF- κB/Hif-1 α Signaling. BIOMED RESEARCH INTERNATIONAL 2020; 2020:8978704. [PMID: 32420378 PMCID: PMC7204316 DOI: 10.1155/2020/8978704] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Revised: 04/11/2020] [Accepted: 04/17/2020] [Indexed: 01/29/2023]
Abstract
Hypoxia-induced neuroinflammation typically causes neurological damage and can occur during stroke, neonatal hypoxic-ischemic encephalopathy, and other diseases. Propofol is widely used as an intravenous anesthetic. Studies have shown that propofol has antineuroinflammatory effect. However, the underlying mechanism remains to be fully elucidated. Thus, we aimed to investigate the beneficial effects of propofol against hypoxia-induced neuroinflammation and elucidated its potential cellular and biochemical mechanisms of action. In this study, we chose cobalt chloride (CoCl2) to establish a hypoxic model. We found that propofol decreased hypoxia-induced proinflammatory cytokines (TNFα, IL-1β, and IL-6) in BV2 microglia, significantly suppressed the excessive production of reactive oxygen species, and increased the total antioxidant capacity and superoxide dismutase activity. Furthermore, propofol attenuated the hypoxia-induced decrease in mitochondrial membrane potential andy 2 strongly inhibited protein expression of nuclear factor-kappa B (NF-κB) subunit p65 and hypoxia inducible factor-1α (Hif-1α) in hypoxic BV2 cells. To investigate the role of NF-κB p65, specific small interfering RNA (siRNA) against NF-κB p65 were transfected into BV2 cells, followed by exposure to hypoxia for 24 h. Hypoxia-induced Hif-1α production was downregulated after NF-κB p65 silencing. Further, propofol suppressed Hif-1α expression by inhibiting the upregulation of NF-κB p65 after exposure to hypoxia in BV2 microglia. In summary, propofol attenuates hypoxia-induced neuroinflammation, at least in part by inhibiting oxidative stress and NF-κB/Hif-1α signaling.

Abstract
Asthma is a chronic inflammatory disease that represents high hospitalizations and deaths in world. Copaiba oil (CO) is popularly used for relieving asthma symptoms and has already been shown to be effective in many inflammation models. This study aimed to investigate the immunomodulatory relationship of CO in ovalbumin (OVA)-induced allergic asthma. The composition of CO sample analyzed by GC and GC-MS and the toxicity test was performed in mice at doses of 50 or 100 mg/kg (by gavage). After, the experimental model of allergic asthma was induced with OVA and mice were orally treated with CO in two pre-established doses. The inflammatory infiltrate was evaluated in bronchoalveolar lavage fluid (BALF), while cytokines (IL-4, IL-5, IL-17, IFN-γ, TNF-α), IgE antibody and nitric oxide (NO) production was evaluated in BALF and lung homogenate (LH) of mice, together with the histology and histomorphometry of the lung tissue. CO significantly attenuated the number of inflammatory cells in BALF, suppressing NO production and reducing the response mediated by TH2 and TH17 (T helper) cells in both BALF and LH. Histopathological and histomorphometric analysis confirmed that CO significantly reduced the numbers of inflammatory infiltrate in the lung tissue, including in the parenchyma area. Our results indicate that CO has an effective in vivo antiasthmatic effect.

Abstract
The complexity of the pathogenetic mechanisms of the development of chronic inflammation in asthma determines its heterogeneity and insufficient treatment effectiveness. Nuclear transcription factors, which include peroxisome proliferator-activated receptors, that is, PPARs, play an important role in the regulation of initiation and resolution of the inflammatory process. The ability of PPARs to modulate not only lipid homeostasis but also the activity of the inflammatory response makes them an important pathogenetic target in asthma therapy. At present, special attention is focused on natural (polyunsaturated fatty acids (PUFAs), endocannabinoids, and eicosanoids) and synthetic (fibrates, thiazolidinediones) PPAR ligands and the study of signaling mechanisms involved in the implementation of their anti-inflammatory effects in asthma. This review summarizes current views on the structure and function of PPARs, as well as their participation in the pathogenesis of chronic inflammation in asthma. The potential use of PPAR ligands as therapeutic agents for treating asthma is under discussion.

Abstract
OBJECTIVE To establish and evaluate an ovalbumin (OVA)-induced bronchial asthma model in mice with intrauterine growth retardation (IUGR), and to explore the molecular mechanism of relationship between IUGR and asthma. METHODS A total of 16 pregnant BALB/c female mice were divided into a low-protein diet group (n=8) and a normal-protein diet group (n=8), which were fed with low-protein (8%) diet and normal-protein (20%) diet respectively. The neonatal mice were weighed 6 hours after birth. Sixteen male neonatal mice with IUGR were randomly chosen from the low-protein diet group and enrolled in the IUGR group, and 16 male neonatal mice from the normal-protein diet group were enrolled in the control group. Blood samples were collected from the mice in both groups for testing of blood glucose. Enzyme-linked immunosorbent assay (ELISA) was used to determine serum insulin level. The mice in the control group were randomized into a control + PBS group and a control + OVA group (n=8 each). The mice in the IUGR group were randomized into an IUGR + PBS group and an IUGR + OVA group (n=8 each). Six-week-old mice in the control + OVA and IUGR + OVA groups were subjected to intraperitoneal injection of 2 mg/mL OVA for sensitization and aerosol inhalation of 1% OVA for challenge. Mice in the control + PBS group and the IUGR + PBS group were treated with an equivalent amount of PBS. ELISA was used to determine serum IgE level in the mice in each group. Bronchoalveolar lavage fluid (BLF) was collected from the mice in each group for cell counting. The lung tissue of the mice in each group was stained with hematoxylin and eosin to observe pathological changes. RESULTS The body weight at 6 hours after birth was significantly lower for neonatal mice in the low-protein diet group compared with those in the normal-protein diet group (P<0.01). The IUGR group had a significantly lower serum insulin level than the control group (P<0.01). The IUGR + PBS group had a significantly lower IgE level than the control + PBS group (P<0.01). Compared with the control + PBS and IUGR + PBS groups, the control + OVA and IUGR + OVA groups had a significantly increased IgE level, and the IgE level was significantly higher in the IUGR + OVA group than in the control + OVA group (P<0.01). Compared with the control + PBS and IUGR + PBS groups, the control + OVA and IUGR + OVA groups had significantly increased counts of leukocytes, eosinophils, lymphocytes, and macrophages in the BLF (P<0.01). The pulmonary alveoli of OVA-induced IUGR mice showed massive inflammatory cell infiltration and damage of intercellular continuity. Meanwhile, airway epithelial cell proliferation, bronchial wall thickening, bronchial lumen narrowing, and massive inflammatory cell infiltration around the bronchi and the vascular wall were observed. CONCLUSIONS An OVA-induced bronchial asthma model has been successfully established in the mice with IUGR induced by low-protein diet, which provides a basis for further study of the molecular mechanism of relationship between IUGR and airway inflammation.

Abstract
This study is to determine the role and mechanism of cryptotanshinone (CTS) in allergic airway inflammation. Asthma induced by OVA was established in BALB/c mice. We found increased airway hyperresponsiveness (AHR), increased inflammatory cell infiltration, elevated levels of TNF-α, interleukin-1β (IL-1β), IL-4, IL-5, IL-6 and IL-13, decreased interferon gamma (IFN-γ) in lung tissue, increased content of total immunoglobulin E (IgE), OVA specific IgE, Eotaxin, ICAM-1, VCAM-1, nuclear factor-kappaB (NF-κB) and phosphorylation of p38 MAPK in lung tissue. However, the administration of CTS significantly decreased AHR in asthmatic mice, reduced inflammation around the bronchioles and inflammatory cells around airway, regulated cytokine production, reduced the total IgE and OVA-specific IgE levels, and inhibited NF-κB activation and p38 MAPK phosphorylation. In vitro experiments in 16 HBE cells revealed that CTS attenuated CAM-1 and IL-6 expression. These results indicate that CTS alleviates allergic airway inflammation by modulating p38 MAPK phosphorylation and NF-κB activation.

Abstract
Saxagliptin (Saxa), a dipeptidyl dipeptidase-4 (DPP-4) inhibitor, is widely used for the treatment of type 2 diabetes mellitus. It has been documented to have immunomodulatory and anti-inflammatory actions. Our objective was to delineate the protective effect and the underlying mechanism of Saxa-in comparison with Dexamethasone (Dexa) - in airway inflammation induced by ovalbumin (OVA) in mice. METHODS Mice were OVA-sensitized and challenged for the induction of acute asthma. Mice were orally administrated Saxa or Dexa. Total and differential cell counts, lactate dehydrogenase (LDH) and total protein concentrations were assessed in bronchoalveolar lavage fluid (BALF). The toll-like receptor 4 (TLR4), nuclear factor-kappa B (NF-kB), reduced glutathione (GSH), and total nitrate/nitrite products (NOx) levels as well as myeloperoxidase (MPO) activity in lung tissues were measured. Histopathological examination of the lung specimens was carried out using the hematoxylin and eosin (H & E) staining. RESULTS Histopathological examination revealed that both Saxa and Dexa ameliorated OVA-induced inflammatory changes and significantly reduced total and differential leukocyte counts, LDH and total protein level in BALF upon comparison with OVA group. In addition, both treatments significantly mitigated OVA-induced oxidative stress as evidenced by diminished lung NOx level and MPO activity and elevated GSH level. The elevation of TLR4 and NF-kB levels in lung tissue were ameliorated by Saxa and Dexa administration. CONCLUSION Saxa had marked antiasthmatic effect in OVA-induced allergic asthma through modulation of TLR4 and NF-κB signaling. Also, Saxa may represent a promising therapeutic agent for acute allergic asthma.

Abstract
Pistacia weinmannifolia (Anacardiaceae) has been used in herbal medicine for the treatment of influenza, dysentery and enteritis in China. It was recently observed that P. weinmannifolia root extract (PWRE) exerts anti‑inflammatory effects both in in vitro and in vivo models. Based on the results from previous studies, the present study investigated the protective effect of PWRE on airway inflammation and mucus hypersecretion. Treatment with PWRE significantly decreased the number of eosinophils and the levels of Th2 cytokines, such as interleukin (IL)‑4, IL‑5 and IL‑13, in the bronchoalveolar lavage fluid (BALF) of OVA‑exposed mice. PWRE decreased the high serum levels of total and OVA‑specific immunoglobulin E. PWRE also effectively inhibited the influx of inflammatory cells into the lung, as well as airway mucus hypersecretion. In addition, the increased level of monocyte chemoattractant protein‑1 was significantly decreased with the PWRE treatment in the BALF of OVA‑exposed mice and in lipopolysaccharide‑stimulated RAW264.7 macrophages. These protective effects of PWRE on OVA‑induced pulmonary inflammation were accompanied by the downregulation of mitogen associated protein kinases and nuclear factor‑κB activation. Thus, the results from the present study indicate that PWRE could be valuable adjuvant for the treatment of asthma.

[PMID: 31489660 DOI: 10.1111/jfbc.12973] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2019] [Revised: 05/21/2019] [Accepted: 06/13/2019] [Indexed: 12/11/2022]
Abstract
We investigated the antiasthmatic effect of mogroside V (Mog V) in mice with ovalbumin (OVA)-induced asthma. Administration of Mog V effectively attenuated OVA-induced airway hyperresponsiveness and reduced the number of inflammatory cells in bronchoalveolar lavage fluid (BALF). Histological examination showed that Mog V reduced the inflammatory infiltration of the lungs in the asthmatic mice. ELISAs suggested that Mog V effectively decreased the levels of IL-4, IL-5, and IL-13 in BALF and serum levels of OVA-specific IgE and IgG1 in the asthmatic mice. A quantitative reverse-transcription PCR assay also indicated that Mog V decreased the mRNA levels of IL-17A, IL-23, and RORγt in the lungs of the asthmatic mice (the opposite effect on Foxp3 mRNA). Furthermore, Mog V significantly reduced the OVA-induced activation of NF-κB in the lungs. This study indicates that Mog V alleviates OVA-induced inflammation in airways, and this effect is associated with a reduction in NF-κB activation. PRACTICAL APPLICATIONS: A traditional Chinese medicine herb has been reported to have a strong curative effect on asthma in clinical practice. Siraitia grosvenorii is known in China as a functional food product with the ability to improve lung function. Mogroside V is a triterpene glycoside isolated from S. grosvenorii. Nonetheless, the antiasthmatic effect of mogroside V has not been evaluated yet. The aim of this study was to investigate the antiasthmatic activity of mogroside V in mice with chemically induced asthma. The data from this study will provide some scientific evidence supporting wider use of S. grosvenorii in functional foods.

Int Immunopharmacol 2019; 74:105706. [PMID: 31254955 DOI: 10.1016/j.intimp.2019.105706] [Citation(s) in RCA: 59] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2019] [Revised: 06/13/2019] [Accepted: 06/14/2019] [Indexed: 12/21/2022]
Abstract
Linalool is a natural product present in fruits and aromatic plants with biological activities. Researchers have reported that the inhalation of linalool exerts anti-inflammatory activities. In this study, we examined the therapeutic effects of linalool on airway inflammation and mucus overproduction in mice with allergic asthma. Oral administration of linalool significantly inhibited the levels of eosinophil numbers, Th2 cytokines and immunoglobulin E (IgE) caused by ovalbumin (OVA) exposure. Linalool exerted preventive effects against the influx of inflammatory cells and mucus hypersecretion in the lung tissues. Linalool also dose-dependently decreased the levels of inducible nitric oxide synthase (iNOS) expression and protein kinase B (AKT) activation in the lung tissues. Linalool effectively downregulated the activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-κB (NF-κB) caused by OVA exposure. Furthermore, linalool exerted inhibitory effect on OVA-induced airway hyperresponsiveness (AHR). In the in vitro study, the increased secretion of MCP-1 was attenuated with linalool treatment in lipopolysaccharide (LPS)-stimulated H292 airway epithelial cells. In conclusion, linalool effectively exerts a protective role in OVA-induced airway inflammation and mucus hypersecretion, and its protective effects are closely related to the downregulation of inflammatory mediators and MAPKs/NF-κB signaling.

Physalis peruviana L. inhibits ovalbumin‑induced airway inflammation by attenuating the activation of NF‑κB and inflammatory molecules. Int J Mol Med 2019; 43:1830-1838. [PMID: 30816433 PMCID: PMC6414162 DOI: 10.3892/ijmm.2019.4110] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Accepted: 02/22/2019] [Indexed: 12/25/2022] Open
Abstract
Physalis peruviana L. (PP) is well known for its various properties, including its antioxidant property. In our previous study, the protective effects of PP against cigarette smoke‑induced airway inflammation were confirmed. The purpose of the present study was to evaluate the anti‑inflammatory effect of PP against ovalbumin (OVA)‑induced airway inflammation. Treatment with PP inhibited the numbers of eosinophils and the levels of inflammatory cytokines, including interleukin (IL)‑4, IL‑5 and IL‑13, in the bronchoalveolar lavage fluid (BALF) of animal models with OVA‑induced allergic asthma. PP also significantly decreased the production of total immunoglobulin E in the serum. Lung sections stained with hematoxylin and eosin revealed that the influx of inflammatory cells was decreased in the lungs of mice treated with PP compared with cells in the OVA group. The increased expression levels of monocyte chemoattractant protein‑1 (MCP‑1) and T cell marker KEN‑5 were also reduced following PP treatment in the lung tissues compared with those in the OVA group. The PAS staining results showed that PP attenuated the overproduction of mucus in the lung. Additionally, western blot analysis revealed that PP significantly downregulated the activation of nuclear factor‑κB/p38 mitogen‑activated protein kinase/c‑Jun N‑terminal kinase, and upregulated the expression of heme oxgenase‑1 in the lungs. In an in vitro experiment, PP effectively reduced the levels of LPS‑stimulated MCP‑1 in a concentration‑dependent manner. Taken together, these results indicate that PP has considerable potential in the treatment of allergic asthma.

Abstract
S-Allyl cysteine (SAC) is an active component in garlic and has various pharmacological effects, such as anti-inflammatory, anti-oxidant, and anti-cancer activities. In this study, we explored the suppressive effects of SAC on allergic airway inflammation induced in an ovalbumin (OVA)-induced asthma mouse model. To induce asthma, BALB/c mice were sensitized to OVA on days 0 and 14 by intraperitoneal injection and exposed to OVA from days 21 to 23 using a nebulizer. SAC was administered to mice by oral gavage at a dose of 10 or 20 mg/kg from days 18 to 23. SAC significantly reduced airway hyperresponsiveness, inflammatory cell counts, and Th2 type cytokines in bronchoalveolar lavage fluid induced by OVA exposure, which was accompanied by reduced serum OVA-specific immunoglobulin E. In histological analysis of the lung tissue, administration of SAC reduced inflammatory cell accumulation into lung tissue and mucus production in airway goblet cells induced by OVA exposure. Additionally, SAC significantly decreased MUC5AC expression and nuclear factor-κB phosphorylation induced by OVA exposure. In summary, SAC effectively suppressed allergic airway inflammation and mucus production in OVA-challenged asthmatic mice. Therefore, SAC shows potential for use in treating allergic asthma.

Abstract
To explore the effects of aloperine (ALO) on allergic airway inflammation, we investigated whether its mechanism is related with NF-κB, MAPK, and Nrf2/HO-1 signaling pathways. Histochemical staining and inflammatory cell count were used to observe lung histopathological changes in mice. ELISA was used to detect the content of inflammatory cytokines and IgE in the mouse bronchoalveolar lavage fluid (BALF). Airway hyperresponsiveness (AHR) to inhale methacholine was measured by the plethysmography in conscious mice. Immunohistochemical method was used to detect the expression levels of Nrf2 and HO-1 in lung tissues. The key proteins of MAPK, NF-κB, and Nrf2/HO-1 in lung tissues were quantitatively analyzed by Western blot. Finally, the in vitro effect of ALO on the production of pro-inflammatory mediators and cytokines by lipopolysaccharide-stimulated RAW 264.7 cells was also evaluated. In the ovalbumin (OVA)-induced asthma mouse model, ALO reduced the exudation and infiltration of inflammatory cells and suppressed goblet cell hyperplasia. ALO-treated asthmatic mice also decreased the protein levels of interleukin (IL)-4, IL-5, IL-13, IFN-γ, and IgE in BALF and attenuated AHR. Furthermore, ALO inhibited the expression of key proteins of MAPK and NF-κB pathways, and increased the expression of Nrf2/HO-1 in OVA-challenged mice. Additional in vitro study has shown that ALO abrogates the macrophage production of inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-α, IL-6, and IL-1β. Taken together, ALO attenuated allergic airway inflammation through regulating NF-κB, MAPK, and Nrf2/HO-1 signaling pathways. The results suggest the utility of ALO as an anti-inflammatory agent for the treatment of asthma.

Abstract
Asthma is a chronic inflammatory disorder of the respiratory tract that is characterized by reversible airflow obstruction and airway hyperresponsiveness. The non-atopic variant of asthma that appears later in life has no allergic background and is more severe and resistant to standard treatment. Hapten-induced asthma models can be utilized to investigate mechanisms behind the development of non-atopic and occupational asthma, in which non-allergic processes seems to play significant role. The development of adequate animal models of non-allergic asthma is a necessary prerequisite both for understanding the pathophysiology of non-allergic asthma and for the possibility of testing new therapies. Still, there is no ideal model that represents all the hallmarks of this complex disease. In this review, we examine the most popular hapten-induced murine models of occupational and non-atopic asthma. For this reason, we describe the most popular sensitizing haptens, sensitization and challenge protocols, symptoms produced by asthma, and advantages and disadvantages of the models.

Abstract
BACKGROUND The present study aimed to investigate the potential effects of propofol on ankle fracture healing in children and the underlying molecular mechanisms. MATERIAL AND METHODS We first detected the levels of inflammatory cytokines from peripheral blood in children with or without ankle fracture using quantitative real-time polymerase chain reaction (qRT-PCR) and ELISA assay. Then, effects of propofol on inflammatory response in MG-63 cells were investigated. MG-63 cells were pre-treated with or without propofol and then stimulated with 1 μM bradykinin (BK). The productions of cytokines from MG-63 cells were determined by using qRT-PCR and Western blot assay. The expression levels of p-p38, NF-κB p-p65, NLRP3, ASC, caspase-1, and COX-2 were measured by Western blot and/or qRT-PCR. RESULTS The results showed that, compared with the healthy children, the levels of tumor necrosis factor (TNF-α), interleukin (IL)-1β, and IL-6 were significantly up-regulated in children with fractured ankles. No cytotoxicity was observed in MG-63 cells after propofol treatment. BK treatment significantly enhanced TNF-α, IL-1β, and IL-6 expression levels, and these enhancements were reduced by propofol treatment in a dose-dependent manner. Moreover, BK-induced up-regulation of p-p38, NF-κB p-p65, NLRP3, ASC, caspase-1, and COX-2 was dose-dependently down-regulated by propofol treatment. CONCLUSIONS Propofol prevents inflammation in MG-63 cells by regulating p38MAPK-NF-κB pathway, NLRP3 inflammasome, and COX-2 expression. Our findings indicate the benefits of propofol in fracture healing, and provide a more theoretical basis for the clinical treatment of fractures.
