Abstract
PURPOSE Severe asthma (SA) is characterized by persistent airway inflammation and remodeling, followed by lung function decline. The present study aimed to evaluate the role of tissue inhibitor of metalloproteinase-1 (TIMP-1) in the pathogenesis of SA. METHODS We enrolled 250 adult asthmatics (54 with SA and 196 with non-SA) and 140 healthy controls (HCs). Serum TIMP-1 levels were determined by enzyme-linked immunosorbent assay. The release of TIMP-1 from airway epithelial cells (AECs) in response to stimuli as well as the effects of TIMP-1 on the activations of eosinophils and macrophages were evaluated in vitro and in vivo. RESULTS Significantly higher levels of serum TIMP-1 were noted in asthmatics than in HCs, in the SA group than in non-SA group, and in the type 2 SA group than in non-type 2 SA group (P < 0.01 for all). A negative correlation between serum TIMP-1 and FEV1% values (r = -0.400, P = 0.003) was noted in the SA group. In vitro study demonstrated that TIMP-1 was released from AECs in response to poly I:C, IL-13, eosinophil extracellular traps (EETs) and in coculture with eosinophils. TIMP-1-stimulated mice showed eosinophilic airway inflammation, which was not completely suppressed by steroid treatment. In vitro and in vivo functional studies showed that TIMP-1 directly activated eosinophils and macrophages, and induced the release of EETs and macrophages to polarize toward M2 subset, which was suppressed by anti-TIMP-1 antibody. CONCLUSIONS These findings suggest that TIMP-1 enhances eosinophilic airway inflammation and that serum TIMP-1 may be a potential biomarker and/or therapeutic target for type 2 SA.

Ex vivo Immuno-modulatory effect of Echinococcus granulosus laminated layer during allergic rhinitis and allergic asthma: A study in Algerian Patients. Exp Parasitol 2023; 250:108535.

Abstract
The effect of helminthic infections on allergic diseases and asthma is still inconclusive. Moreover, there is considerable evidence suggesting that nitric oxide (NO), metalloproteinases and pro-inflammatory cytokines play a significant role in the physiopathology of these diseases. In this sense, the aim of our study is to investigate the ex vivo immunomodulatory effect of the laminated layer (LL, outside layer of parasitic cyst) of the helminth Echinococcus granulosus on NO, IL-17A and IL-10 production. In the first step of our study, we evaluated in vivo the NO, MMP-9, IL-17A, IL-10 levels in Algerian patients with allergic asthma and allergic rhinitis and their changes in relation with exacerbation status of the patients. In the principal part of our work, we assessed NO, IL-10 and IL-17A levels in supernatants of patients PBMCs cultures before and after stimulation with LL. Our results indicate a significant reduction in NO production by PBMCs of patients with allergic rhinitis and allergic asthma whether mild, moderate or severe after stimulation with LL. Interestingly, LL induces a significant decrease in the production of NO and IL17-A levels as well as an increase in the production of IL-10 in the cultures performed with PBMC of patients with severe allergic asthma. Importantly, our data indicate that LL exert a down-modulatory effect on inflammatory mediators (NO, IL-17A) and up immune-regulatory effect on IL-10 production. Collectively, our study supports the hygiene hypothesis suggesting that Echinococcus granulosus infection like other helminths could prevent and/or modulate inflammation responses during inflammatory diseases.

Abstract
Zinc (Zn) is an essential trace element for the body. Studies have confirmed that Zn deficiency can cause oxidative stress. The purpose of the present study was designed to investigate the effect of Zn on fibrosis in lung of mice and its mechanism. Mice were fed with different Zn levels dietary, then we found that the Zn-deficient diet induced a decrease of Zn level in lung tissue. The results also revealed the alveolar structure hyperemia and an inflammatory exudated in the alveolar cavity. Moreover, immunohistochemical results showed that the expression of α-smooth muscle actin (α-SMA) increased. And the Sirius red staining indicated an increase in collagen with Zn deficiency. Furthermore, oxygen radicals (ROS) levels were significantly increased, and the antioxidants were significantly decreased. Meanwhile, inflammatory factors (TNF-α and IL-1β) were remarkably increased, and the ELISA results showed that collagen I, III, and IV and fibronectin (FN) were increased. In addition, the expressions of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinase (TIMPs) were detected by qPCR. The results showed that the expression of TIMPs was increased but the expression of MMPs was decreased. The results of the experiment in vitro were consistent with that in vivo. All the results indicated that Zn deficiency aggravated the oxidative stress response of lung tissue to induce inflammation, leading to fibrosis in lung.

Abstract
Switching of airway smooth muscle (ASM) cell phenotype from differentiated-contractile to dedifferentiated-proliferative/synthetic state often occurs in asthmatic subjects with airway dysfunction. Evidence has been provided that chloroquine (an agonist of bitter taste receptors) presented benefits to ASM cell function implicated in asthma. However, the underlying mechanism is unclear. House dust mite (HDM)-sensitized mice were administered with chloroquine or dexamethasone before challenge. BALF and lung tissue were obtained for cell counting, histological analysis or ELISA. Primary cultured ASM cells were stimulated with transforming growth factor (TGF)-β1 or H2O2. Cells and supernatant were collected for the detection of ASM phenotype, ROS level, and proinflammatory cytokine production. In HDM-sensitized mice, chloroquine attenuated airway hyperresponsiveness (AHR), inflammation and remodeling with an inhibition of immunoglobulin E, IL-4/-13, and TGF-β1 in BALF. ASM cell proliferation (PCNA), hypertrophy (α-SMA), and parasecretion (MMP-9 and MMP-13) were strongly suppressed by chloroquine, hinting the rebalance of the heterogeneous ASM populations in asthmatic airway. Our data in vitro indicated that chloroquine markedly restrained maladaptive alteration in ASM phenotype in concert with a remission of ROS. Using H2O2 and PI3K inhibitor (LY294002), we found that the inhibition of oxidative stress level and ROS-AKT signal by chloroquine may serve as a potential mechanism that dedicates to the restoration of the phenotypic imbalance in ASM cells. Overall, the present findings suggested that chloroquine improves asthmatic airway function by controlling ASM cell phenotype shift, sketching a novel profile of chloroquine as a new therapeutic candidate for airway remodeling.

Abstract
Background Allergic rhinitis (AR) is an upper respiratory tract inflammation disease caused by IgE-mediated reactions against inhaled allergens. The incidence of AR is significantly increasing throughout the world. Hence, more specific, and sensitive gene biomarkers and understanding the underlying pathways are necessary to further explore the AR pathogenesis. Objective To identify gene biomarkers in nasal mucosa and in blood from AR patients which could be used in AR diagnosis. Methods The gene expression profiles of GSE43523 from nasal epithelial cells and GSE75011 from Th2-enriched CD4+ T cells in blood were downloaded from the Gene Expression Omnibus database. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses and protein–protein interaction (PPI) network analysis were conducted to investigate the functional changes of genes. The receiver operating characteristic (ROC) curves were used to assess the diagnostic values of the hub genes. Real-time quantitative PCR (RT-qPCR) was performed to validate the hub genes. Results Significant differentially enriched gene signatures in AR patients were identified in nasal epithelial cells (n-DEGs) and in blood (t-DEGs). Signatures associated with axoneme, extracellular matrix, collagen fibril organization, cell motility, calcium ion binding, and so on were more enriched in n-DEGs, whereas signatures associated with TNF signaling pathway, detoxification of inorganic compound, and cellular response to corticotropin-releasing hormone stimulus were enriched in t-DEGs. In addition, we identified 8 hub genes and 14 hub genes from n-DEGs and t-DEGs, respectively. The combination of POSTN in nasal mucosa and PENK and CDC25A in blood was constructed with a good AR predicting performance. The area under the curve (AUC) of the ROC curve of 3 hub genes’ combination was 0.98 for AR diagnosis. Conclusion This study utilized gene expression profiles and RT-qPCR validation on nasal mucosa and blood from AR patients to investigate the potential biomarkers for AR diagnosis.

Abstract
INTRODUCTION Airway inflammation in asthma is accompanied by reconstruction of the bronchial wall extracellular matrix that most likely occurs with a contribution of matrix metalloproteinases (MMPs). Recently we have reported that omalizumab may decrease reticular basement membrane (RBM) thickness together with fibronectin deposits in asthmatic airways, although mechanisms involved are unknown. OBJECTIVE In the present study, we have investigated the impact of omalizumab on MMPs concentrations in bronchoalveolar lavage fluid (BAL) of asthmatic subjects in relation to airway remodeling changes in histology. PATIENTS AND METHODS The study group consisted of 13 severe allergic asthmatics treated with omalizumab for at least 12 months. In each subject, clinical and laboratory parameters, bronchoscopy with BAL, and endobronchial biopsy were evaluated before and after the biologic therapy. RBM thickness, fibronectin, and collagen deposits in bronchial mucosa specimens were analyzed in histology. The investigations also included BAL cytology and BAL concentrations of MMP-2, -3, and -9. RESULTS Omalizumab was related to a decrease in all measured MMPs in BAL (p < 0.001, each), although such declines were not observed in each patient. The depletions were associated with a lower asthma exacerbation rate and better asthma control. Interestingly, patients who showed a decline in at least one MMP (n = 10, 77%) were characterized by a higher decrease in the RBM thickness (-1.61 [-2.02 to -0.6] vs. -0.06 [-0.09 to +3.3], p = 0.03). Likewise, individuals with lower concentrations of MMP-9 after omalizumab (n = 7, 58%) had a greater reduction in the RBM layer as compared to those with steady MMP-9 levels (-1.8 [-2.4 to -1.14] vs. -0.13 [-0.6 to -0.06] μm, p = 0.03). Moreover, the latter group also had unfavorable higher collagen I accumulation after biologic (42 [20 to 55] vs. 0 [-10 to 20]%, respectively, p = 0.03). Higher concentrations of MMPs in BAL at baseline were related to the lower systemic steroid dose and better omalizumab response concerning the decline in RBM thickness. CONCLUSION Our data suggest that omalizumab therapy is associated with decreased BAL MMPs concentration in the subgroup of asthma patients. The decline was linked with a reduction in the RBM thickness what might play a beneficial role in airway remodeling.

Abstract
Matrix metalloproteinases (MMPs) are closely associated with various physiological and pathological processes, and have been regarded as potential biomarkers for severe diseases including cancer. Accurate determination of MMPs would advance our understanding of their roles in disease progression, and is of great significance for disease diagnosis, treatment and prognosis. In this review, we present a comprehensive overview of the developed bioassays/biosensors for detection of MMPs, and highlight the recent advancement in nanomaterial-based immunoassays for MMP abundance measurements and nanomaterial-based biosensors for MMP activity determination. Enzyme-linked immunosorbent assay (ELISA)-based immunoassays provide information about total levels of MMPs with high specificity and sensitivity, while target-based biosensors measure the amounts of active MMPs, and allow imaging of MMP activities in vivo. For multiplex and high-throughput analysis of MMPs, microfluidics and microarray-based assays are described. Additionally, we put forward the existing challenges and future prospects from our perspective.

Abstract
Introduction: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a complex immunological upper airway disease . CRSwNP, particularly in Caucasians, often has a more distinct T2 inflammatory endotype. IL-4 and IL-13 are key upstream cytokines that help establish and sustain T2 inflammation as well as strongly influencing tissue remodeling. They have a shared signaling receptor IL-4Rα. An attractive and novel therapeutic approach is by way of blocking IL-4 and IL-13 simultaneously via inhibiting IL-4Rα. Dupilumab is a murine derived fully human monoclonal inhibitory antibody directed against IL-4Rα which thereby prevents IL-4/IL-13 cell signaling. Following successful Phase 3 studies dupilumab has become the first licensed biologic for treating CRSwNP. Areas covered: This review covers the essential immunology of CRSwNP in the context of IL-4 and IL-13 signaling via IL-4Rα. The potential mechanisms by which therapeutic improvements occur with dupilumab are evaluated. IL-4, IL-13, dupilumab and rhinosinusitis were used as the search terms in PubMed and Google Scholar through to August 2020. Expert commentary: Dupilumab has the potential to transform the care for patients with CRSwNP. It is essential that further studies are conducted promptly to identify disease-specific biomarkers and clinical traits to guide clinicians on best patient selection thereby ensuring optimal dupilumab outcomes.

Abstract
In this study, we aimed to identify signaling alteration caused by exposure to diesel exhaust particles (DEPs) using primary human nasal epithelial cells (PHNECs). Global gene expression profiles in PHNECs following 50 and 200 μg/ml of DEP exposure were identified using microarray analysis. To cover the limitation of array-based mRNA expression analysis, text-mining-based software was used to analyze the integrative biological networks and relevant disease-focused functions among identified DEP-responsive genes. The confidence was valued based on the connectivity between the analyzed pathway and marker candidates. Through a literature-based pathway analysis, the stimulation of inflammation- and immune response-related processes mediated by TNF were predicted as major signaling alterations in PHNECs caused by DEP exposure. CSF3, CXCL8, MMP1, and VEGFA were identified as key hub genes in the predicted pathway. Significant expression level changes in the five key genes following DEP exposure were validated in terms of protein and mRNA expression. Although further studies are required, our toxicogenomic investigation provides key clues to the exact mechanism underlying DEP-induced nasal inflammatory damage. It also suggests an efficient approach for other research on adverse effects occurring in the upper respiratory tract following DEP exposure.

[PMID: 30846420 PMCID: PMC9422499 DOI: 10.1016/j.bjorl.2019.01.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2018] [Revised: 12/12/2018] [Accepted: 01/08/2019] [Indexed: 11/29/2022] Open
Abstract
Introduction The extent of epithelial lesion in allergic and non-allergic rhinitis and its association with inflammatory changes in nasal lavage has not been clarified. Objective To verify the association between the inflammatory cells in the nasal lavage, epithelial lesion extent and basement membrane thickness, in the nasal mucosa of patients with rhinitis; to determine the cutoff point of the percentage of eosinophils in the nasal lavage associated with the atopic patients. Methods Patients with rhinitis and indication for septoplasty and (or) turbinectomy for turbinate hypertrophy were selected, and were submitted to allergy skin tests, nasal lavage with measurement of albumin and interleukin-8 levels, total and differential counting of cells, and mucosal histopathological analysis to determine the extent of epithelial lesion, and degree of basement membrane thickening. Results Fifty-six patients with a median age of 24.5 years and a diagnosis of allergic rhinitis (n = 36) and non-allergic rhinitis (n = 20) were studied. In atopic subjects, allergy skin tests were positive for Dermatophagoides pteronyssinus in 35 (97.0%) and Lolium perenne in 18 (50.0%). Atopic subjects showed a higher clinical score index of rhinitis compared to non-atopic ones. The total count of cells, neutrophils, and levels of albumin and IL-8 were not different in the nasal lavage of atopic and non-atopic subjects. The cutoff point for eosinophil count in nasal fluid for the distinction between allergic rhinitis and non-allergic rhinitis was 4%. Some degree of epithelial lesion was more frequent in allergic rhinitis (94%) than in non-allergic rhinitis (65%) patients. In the presence of basement membrane thickness, as a marker of remodeling, there was no difference in the nasal lavage of patients with allergic rhinitis and non-allergic rhinitis. Conclusion In this series, 4% was the cutoff point for the number of eosinophils in the nasal lavage, for atopy differentiation. Upper airway remodeling accessed by basement membrane thickness showed similar inflammatory cell infiltrate in the nasal lavage, regardless of the presence of atopy.

Abstract
Mast cells (MCs) are granular cells of the innate immune system which develop from CD34+/CD117+ progenitors and play a role in orchestrating adaptive immune responses. They have a well-known role in allergic reactions following immunoglobulin (Ig)E-mediated activation of the cell-surface expressed IgE high-affinity receptor (FcεRI). MCs can also respond to various other stimuli due to the expression of a variety of receptors including toll-like receptors (TLRs), immunoglobulin (IgG) receptors (FcγR), complement receptors such as C5a (CD88) expressed by skin MCs, neuropeptides receptors including nerve growth factor receptor, (NGFR), cytokines receptors such as (IL)-1R and IL-3R, and chemokines receptors including CCR-1 and CCR-3. MCs release three groups of mediators upon degranulation differentiated according to their chemical composition, storage, and time to release. These include preformed mediators (mainly histamine, tryptase, and chymase), de novo synthesized mediators such as prostaglandin (PG)D2, leukotriene (LT)B4 and LTD4, and cytokines including IL-1β, IL-3, tumor necrosis factor (TNF)α, and transforming growth factor(TGF)-β. Emerging evidence indicates a role for IgE-independent MC activation in the late-stage asthmatic response as well as in non-allergic airway diseases including chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), and lung cancer. MC infiltration/activation has been reported in some, but not all, studies of lung cancer. MC-derived TNF-α possesses tumor-suppressive activity while IL-1β supports tumor progression and metastasis. In IPF lungs, an increase in density of tryptase- and chymase-positive MCs (MCTC) and overexpression of TGF-β support the fibrosis progression. MC-derived chymase activates latent TGF-β that induces the differentiation of fibroblasts to matrix-producing myofibroblasts. In summary, increasing evidence highlights a critical role of MCs in non-allergic diseases that may indicate new approaches for therapy.

Abstract
Background Gene expression patterns (particularly, cilia-associated genes) of nasal mucosa, the first-line defense system, in allergic rhinitis (AR) are not well understood. Objective We sought to screen for AR-associated genes in inferior turbinate (IT) from patients with AR, and to validate the expression of common cilia-related genes and ciliary shedding. Methods Prime View™ Human Gene Expression Array, which consisted of more than 530 000 probes covering more than 36 000 transcripts and variants, was employed to compare individual gene expression of ITs from control subjects (n = 11) and patients with AR (n = 19). Gene ontology (GO) analysis was performed with Cytoscape software. Eight of the common cilia-related genes were validated with quantitative polymerase chain reaction. We applied a semiquantitative scoring system for immunofluorescence assay to demonstrate ciliary shedding in 5 areas per paraffin section, with individual sections being scored between 0 (normal ciliary distribution) and 1 (ciliary shedding). Results Compared with control subjects, 160 (38 upregulated and 122 downregulated) genes were differentially expressed for at least 2 folds (all P < .05) in AR. Seven GO categories were significantly enriched, 4 of which were related to cilium assembly and motility. Quantitative polymerase chain reaction validated the predicted direction of change for common cilia-related gene expression. The ciliary distribution score was significantly higher (more prominent ciliary shedding) in AR than in controls ( P < .05). Conclusion The significant aberrant cilia-related gene expression, revealed by microarray assays, might be the critical driver of AR where ciliary shedding is prominent.

Abstract
BACKGROUND Periodontitis, an inflammatory disease of multibacterial etiology that affects the protective and supporting tissues surrounding teeth, can influence the course of respiratory diseases, such as asthma, due to epithelial alterations arising from inflammatory and immunological processes, bronchial remodeling, or by the aspiration of pathogenic colonizers found in periodontal pockets. This study evaluated the levels of periodontal pathogens Prevotella intermedia, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, and Aggregatibacter actinomycetemcomitans in the subgingival biofilm of individuals with and without severe asthma. METHODS A case-control study enrolling 457 individuals (220 with asthma and 237 without asthma) was conducted at the Program for Control of Asthma in Bahia (ProAR) Clinic located in Salvador, Bahia, Brazil. A structured questionnaire was used to obtain data on sociodemographic, health status, and lifestyle habits. A clinical periodontal assessment was performed, including bleeding on probing, probing depth, and clinical attachment level. Subgingival biofilm was collected at the deepest site of each sextant, and bacterial DNA was extracted. Quantitative real-time PCR analysis was performed to detect and relatively quantify periodontopathogens in the biofilm. RESULTS Statistically significant positive associations were found between periodontitis and severe asthma, (odds ratio [OR]adjusted] : 4.00; 95% confidence interval [CI]: 2.26 to 7.10). High levels of P. intermedia were found in association with the presence of severe asthma (ORadjusted : 2.64; 95% CI: 1.62 to 4.39; P < 0.01). CONCLUSIONS The present results suggest that periodontitis and P. intermedia are associated with severe asthma. However, the functional consequences of this dysbiosis upon asthma susceptibility and its phenotypes remain unclear.

Abstract
Background Allergic rhinitis (AR) has been reported to be associated with chronic rhinosinusitis (CRS). The objective of this study was to investigate the effect of AR on nasal mucosa remodeling in CRS. Methods Patients were enrolled and divided into the following groups: CRS with nasal polyps (NP) with allergic rhinitis (AR)(CRSwNPwAR; n = 20), CRS with NP without AR (CRSwNPsAR; n = 20), CRS without NP with AR (CRSsNPwAR; n = 20), CRS without NP without AR (CRSsNPsAR; n = 20), AR without CRS (AR; n = 20) and controls (n = 14). Eosinophil infiltration, mucus production, and collagen deposition were examined by hematoxylin and eosin, periodic acid schiff and masson’s trichrome staining, respectively. VEGF-A and microvessel density were detected by immunohistochemistry. The expression of remodeling markers, including TGF-β1, MMP-7, MMP-9 and TIMP-1 were measured by Western blot. Results The expression of remodeling factors, including VEGF-A, CD31, CD34 and TIMP-1 were significantly increased in CRSwAR compared to CRSsAR. Goblet cell hyperplasia, as well as VEGF-A, CD31, CD34, and MMP-9 expression were significantly higher in CRSwNPwAR compared to CRSwNPsAR. However, the expression of collagen fibers, MMP-7 and TGF-β1 were significantly higher in CRSsNPwAR compared to CRSsNPsAR. Conclusions AR could enhance the remodeling process in CRS. Moreover, AR had different effects on CRSwNP and CRSsNP.

Abstract
Pulmonary fibrosis is a chronic progressive disease with unknown etiology and has poor prognosis. Polyhexamethyleneguanidine phosphate (PHMG-P) causes acute interstitial pneumonia and pulmonary fibrosis in humans when it exposed to the lung. In a previous study, when rats were exposed to PHMG-P through inhalation for 3 weeks, lung inflammation and fibrosis was observed even after 3 weeks of recovery. In this study, we aimed to determine the time course of PHMG-P-induced lung inflammation and fibrosis. We compared pathological action of PHMG-P with that of bleomycin (BLM) and investigated the mechanism underlying PHMG-P-induced lung inflammation and fibrosis. PHMG-P (0.9 mg/kg) or BLM (1.5 mg/kg) was intratracheally administered to mice. At weeks 1, 2, 4 and 10 after instillation, the levels of inflammatory and fibrotic markers and the expression of inflammasome proteins were measured. The inflammatory and fibrotic responses were upregulated until 10 and 4 weeks in the PHMG-P and BLM groups, respectively. Immune cell infiltration and considerable collagen deposition in the peribronchiolar and interstitial areas of the lungs, fibroblast proliferation, and hyperplasia of type II epithelial cells were observed. NALP3 inflammasome activation was detected in the PHMG-P group until 4 weeks, which is suspected to be the main reason for the persistent inflammatory response and exacerbation of fibrotic changes. Most importantly, the pathological changes in the PHMG-P group were similar to those observed in humidifier disinfectant-associated patients. A single exposure of PHMG-P led to persistent pulmonary inflammation and fibrosis for at least 10 weeks.

Abstract
Background and objective Interleukin (IL)-25 has been shown to play an important role in the pathogenesis of chronic rhinosinusitis with nasal polyps. Nasal polyps are associated with chronic inflammation of the mucous membranes in the paranasal sinuses and are involved in extracellular matrix (ECM) accumulation. The aim of this study is to evaluate the effects of IL-25 on myofibroblast differentiation, ECM production and the expression of matrix metalloproteinases in nasal polyp derived fibroblasts (NPDFs) and to determine the molecular mechanism underlying these processes. Materials and methods A total of 40 patients were enrolled in this study for Immunofluorescence studies. Expression of IL17 receptor B was evaluated by real time reverse transcription polymerase chain reaction (PCR) in NPDFs. NPDFs were stimulated with IL-25 for 48 h in the presence or absence of mitogen-activated protein kinase (MAPK) and NF-κB inhibitors or small interfering RNAs (siRNA). The protein levels of fibrosis active mediators were examined using western blotting. Fibroblast migration was evaluated with a scratch assay. The total collagen amount was analyzed with the Sircol collagen assay. Results IL-25 induced α-SMA, fibronectin, and MMP-1 and -13, which were dependent on IL-17RB. IL-25 also induced activation of NF-κB and mitogen-activated protein kinase (MAPKs). By using the specific inhibitor of ERK, p38, JNK and NF-κB (U, SB, SP and Bay), we found that IL-25-induced expressions of α-SMA, fibronectin, and MMPs was regulated by the signaling pathways of MAPKs and NF-κB. IL-25 also induces α-SMA, fibronectin, and MMPs expression through IL-17RB-dependent pathways in NPDFs. The increased migration ability induced by IL-25 was suppressed by the specific inhibitors of MAPKs and NF-κB. Conclusion Our data indicate that IL-25 induced myofibroblast differentiation, fibronectin production, and MMP-1 and -13 expressions through the signaling pathways of MAPKs and NF-κB. in NPDFs and increased expression of IL-25 were also involved in the pathogenesis of nasal polyposis by affecting nasal fibroblasts in chronic rhinosinusitis with nasal polyps.

Abstract
Background Chronic rhinosinusitis with nasal polyps (NP) (CRSwNP) is classified into eosinophilic and noneosinophilic types based on the level of tissue eosinophilia. The immunopathologic features of Western and Asian CRSwNP differ. Objectives The aim of this study was to investigate the immunopathologic characteristics of Korean patients with eosinophilic NP versus noneosinophilic NP and those with atopic NP versus nonatopic NP. Methods Tissue samples were collected from 81 patients with NP and 24 controls. The clinical characteristics of all the patients were analyzed. Tissues were investigated for expression of chemical mediators, including interleukin (IL) 5, IL-10, IL-17, interferon-γ, and tumor growth factor-β1; transcription factors, including GATA binding protein 3 (GATA-3), forkhead box P3 (Foxp3), retinoic acid–related orphan receptor C (RORC), and T-box transcription factor (T-bet), and extracellular matrix, including collagen type I, fibronectin, tissue inhibitor of metalloproteinase 1, and matrix metalloproteinase (MMP) 9. Results Although the clinical characteristics differed between eosinophilic and noneosinophilic NPs, atopic status did not affect the clinical findings of CRSwNP. Both T-helper 1 and 2 cytokines increased significantly in patients with eosinophilic NP, but atopic status did not affect the expression of any of the chemical mediators. GATA-3 messenger RNA (mRNA) expression increased significantly in patients with eosinophilic NP, and RORC mRNA expression increased significantly in patients with noneosinophilic NP. T-bet, RORC, and Foxp3 mRNA expression increased significantly in patients with nonatopic NP. Fibronectin and MMP-9 mRNA expression increased significantly in patients with noneosinophilic NP, whereas only MMP-9 mRNA increased significantly in patients with eosinophilic and those with noneosinophilic NP. Conclusion The immunopathologic characteristics differed between eosinophilic NP and noneosinophilic NP and between atopic NP and nonatopic NP. The different underlying pathogenic processes may influence the development of Korean NP.

Abstract
Diagnosis early in life, sensitization, asthma endotypes, monitoring of disease and treatment progression are key motivations for the exploration of biomarkers for allergic rhinitis and allergic asthma. The number of genes related to allergic rhinitis and allergic asthma increases steadily; however, prognostic genes have not yet entered clinical application. We hypothesize that the combination of multiple genes may generate biomarkers with prognostic potential. The current review attempts to group more than 161 different potential biomarkers involved in respiratory inflammation to pave the way for future classifiers. The potential biomarkers are categorized into either epithelial or infiltrate-derived or mixed origin, epithelial biomarkers. Furthermore, surface markers were grouped into cell-type-specific categories. The current literature provides multiple biomarkers for potential asthma endotypes that are related to T-cell phenotypes such as Th1, Th2, Th9, Th17, Th22 and Tregs and their lead cytokines. Eosinophilic and neutrophilic asthma endotypes are also classified by epithelium-derived CCL-26 and osteopontin, respectively. There are currently about 20 epithelium-derived biomarkers exclusively derived from epithelium, which are likely to innovate biomarker panels as they are easy to sample. This article systematically reviews and categorizes genes and collects current evidence that may promote these biomarkers to become part of allergic rhinitis or allergic asthma classifiers with high prognostic value.

Endogenous sulfur dioxide alleviates collagen remodeling via inhibiting TGF-β/Smad pathway in vascular smooth muscle cells. Sci Rep 2016; 6:19503. [PMID: 26762477 PMCID: PMC4725894 DOI: 10.1038/srep19503] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2015] [Accepted: 12/09/2015] [Indexed: 02/07/2023] Open
Abstract
The study was designed to investigate the role of endogenous sulfur dioxide (SO2) in collagen remodeling and its mechanisms in vascular smooth muscle cells (VSMCs). Overexpression of endogenous SO2 synthase aspartate aminotransferase (AAT) 1 or 2 increased SO2 levels and inhibited collagen I and III expressions induced by transforming growth factor (TGF)-β1 in VSMCs. In contrast, AAT1 or AAT2 knockdown induced a severe collagen deposition in TGF-β1-treated VSMCs. Furthermore, AAT1 or AAT2 overexpression suppressed procollagen I and III mRNA, upregulated matrix metalloproteinase (MMP)-13 expression, downregulated tissue inhibitors of MMP-1 level, and vice versa. Mechanistically, AAT1 or AAT2 overexpression inhibited phosphorylation of type I TGF-β receptor (TβRI) and Smad2/3 in TGF-β1-stimulated VSMCs. Whereas SB431542, an inhibitor of TGF-β1/Smad signaling pathway, attenuated excessive collagen deposition induced by AAT knockdown. Most importantly, ectopically expressing AAT or exogenous addition of 100 μM SO2 blocked AAT deficiency-aggravated collagen accumulation in TGF-β1-stimulatd VSMCs, while no inhibition was observed at 100 μM ethyl pyruvate. These findings indicated that endogenous SO2 alleviated collagen remodeling by controlling TGF-β1/TβRI/Smad2/3-mediated modulation of collagen synthesis and degradation.

Abstract
The present study aimed to investigate the immunomodulatory effect of jacaric acid, a naturally-occurring conjugated linolenic acid isomer that can be found in jacaranda seed oil, on the activated human mast cell line-1 (HMC-1). Our previous studies have demonstrated that jacaric acid only exerted minimal, if any, cytotoxicity on normal murine cells. In the present study, jacaric acid at concentrations ≤100 µM did not exhibit direct cytotoxicity on human peripheral blood mononuclear cells after 72 h of incubation, as determined by the MTT reduction assay. By contrast, jacaric acid could alleviate the calcium ionophore A23187 and phorbol 12-myristate 13-acetate-triggered allergic response in the HMC-1 cells at concentrations that were non-cytotoxic to the HMC-1 cells. Following pre-treatment with jacaric acid, the secretion of two inflammatory mediators, β-N-acetylglucosaminidase and tryptase, as well as the T helper 2 cytokines [interleukin (IL)-4 and IL-13] was significantly reduced in HMC-1 cells. The alleviation of allergic response was accompanied by downregulation of the matrix metalloproteinase-2 and -9 proteins and upregulation of the tissue inhibitor of metalloproteinase-1 protein. Collectively, the results indicated that the naturally-occurring jacaric acid exhibits a suppressive effect on the allergic response in activated human mast cells in vitro, and this could not be attributed to the direct cytotoxicity of jacaric acid on the treated cells.

Abstract
BACKGROUND Microbes and allergens can stimulate the nasal mucosa, potentially leading to the development of acute bacterial rhinosinusitis (ABRS). This study was designed to determine if allergen exposure alters the sinonasal microbiome. METHODS We performed a parallel observational study of healthy adults with seasonal allergic rhinitis (SAR; grass or tree, n = 20) or nonallergic subjects (n = 19). Microbiota specimens were obtained by endoscopy from the middle meatus and vestibule before and during the relevant season and were analyzed by terminal restriction fragment length polymorphism analysis. Differences in bacterial microbiota were assessed by standard ecological measures of bacterial diversity. Quality of life and symptom scores were recorded, and nasal lavages for eosinophils were performed. RESULTS SAR subjects had increased nasal symptoms in season, impaired disease-specific quality of life, and increased nasal eosinophils, compared with no changes in nonallergic subjects. During the season, SAR subjects had a significantly greater variety of organisms in the middle meatus compared with nonallergic subjects (p < 0.036) and increased bacterial diversity (Shannon index, p < 0.013). We found a significant positive correlation between bacterial diversity in the middle meatus during the season and the nasal lavage eosinophil count of SAR subjects. There were no significant changes in the nasal vestibule (p > 0.05, all comparisons). CONCLUSION The interaction of allergy and microbiota may affect the sinonasal physiology, with broad implications for several airway diseases. Characterization of the specific organisms involved using next-generation sequencing may clarify the relationship between allergic inflammation and ABRS. This finding may help explain why allergic inflammation predisposes to ABRS.

Hydrogen sulfide alleviates myocardial collagen remodeling in association with inhibition of TGF-β/Smad signaling pathway in spontaneously hypertensive rats. Mol Med 2015; 20:503-15.

Abstract
The study was designed to explore the role and possible mechanisms of hydrogen sulfide (H2S) in the regulation of myocardial collagen remodeling in spontaneously hypertensive rats (SHRs). We treated nine-week-old male SHRs and age- and sex-matched Wistar-Kyoto rats (WKYs) with NaHS (90 μmol/kg(-1)·day(-1)) for 9 wks. At 18 wks, plasma H2S, tail arterial pressure, morphology of the heart, myocardial ultrastructure and collagen volume fraction (CVF), myocardial expressions of collagen I and III protein and procollagen I and III mRNA, transforming growth factor-β1 (TGF-β1), TGF-β type I receptor (TβR-I), type II receptor (TβR-II), p-Smad2 and 3, matrix metalloproteinase (MMP)-13 and tissue inhibitors of MMP (TIMP)-1 proteins were determined. TGF-β1-stimulated cultured cardiac fibroblasts (CFs) were used to further study the mechanisms. The results showed that compared with WKYs, SHRs showed a reduced plasma H2S, elevated tail artery pressure and increased myocardial collagen, TGF-β1, TβR-II, p-Smad2 and p-Smad3 expressions. However, NaHS markedly decreased tail artery pressure and inhibited myocardial collagen, TGF-β1, TβR-II, p-Smad2 and p-Smad3 protein expressions, but H2S had no effect on the expressions of MMP-13 and TIMP-1. Hydralazine reduced blood pressure but had no effect on myocardial collagen, MMP-13 and TIMP-1 expressions and TGF-β1/Smad signaling pathway. H2S prevented activation of the TGF-β1/Smad signaling pathway and abnormal collagen synthesis in CFs. In conclusion, the results suggested that H2S could prevent myocardial collagen remodeling in SHR. The mechanism might be associated with inhibition of collagen synthesis via TGF-β1/Smad signaling pathway.

Abstract
Socheongryeong‑tang (SCRT) is a herbal formula previously used to treat pulmonary diseases primarily caused by the common cold virus, including airway inflammation, asthma and allergy. The aim of the present study was to investigate the inhibitory effect of SCRT water extract and its 13 constituent components on chemokine and enzyme production in the human bronchial epithelium cell line BEAS‑2B when induced by tumor necrosis factor‑α and interleukin‑4. The chemokines examined included regulated on activation of normal T‑cell‑expressed‑and‑secreted (RANTES), eotaxin and eotaxin‑3. The SCRT water extract demonstrated a dose‑dependent inhibition of RANTES, eotaxin, eotaxin‑3 and matrix metalloproteinase‑9 (MMP‑9) in BEAS‑2B cells. The 13 constituent compounds of SCRT water extract were quantitatively determined, and it was found that gallic acid, 6‑gingerol and methyl eugenol produced the most potent inhibition of RANTES, eotaxin and eotaxin‑3 as well as MMP‑9 activity regardless of their concentration in SCRT water extract. Principal component analysis and hierarchical clustering analysis revealed that the inhibitory effect of these three compounds contributed to that of SCRT water extract. In conclusion, the results of the present study indicated that the inhibitory effects of SCRT on chemokine and enzyme production in BEAS‑2B cells was associated with three of its constituent compounds, gallic acid, 6‑gingerol and methyl eugenol. This therefore suggested the potential use of these compounds as anti‑inflammatory agents.

Abstract
The current study was conducted to investigate the anti-fibrotic effect and its possible underlying mechanisms of thymoquinone (TQ) against hepatic fibrosis in vivo. TQ is the major active compound derived from the medicinal Nigella sativa. Liver fibrosis was induced in male Kunming mice by intraperitoneal injections of thioacetamide (TAA, 200 mg/kg). Mice were treated concurrently with TAA alone or TAA plus TQ (20 mg/kg or 40 mg/kg) given daily by oral gavage. Our data demonstrated that TQ treatment obviously reversed liver tissue damage compared with TAA alone group, characterized by less inflammatory infiltration and accumulation of extracellular matrix (ECM) proteins. TQ significantly attenuated TAA-induced liver fibrosis, accompanied by reduced protein and mRNA expression of α-smooth muscle actin (α-SMA), collagen-І and tissue inhibitor of metalloproteinase-1 (TIMP-1). TQ downregulated the expression of toll-like receptor 4 (TLR4) and remarkably decreased proinflammatory cytokine levels as well. TQ also significantly inhibited phosphatidylinositol 3-kinase (PI3K) phosphorylation. Furthermore, TQ enhanced the phosphorylation adenosine monophosphate-activated protein kinase (AMPK) and liver kinase B (LKB)-1. In conclusion, TQ may reduce ECM accumulation, and it may be at least regulated by phosphorylation of AMPK signaling pathways, suggesting that TQ may be a potential candidate for the therapy of hepatic fibrosis.

Abstract
Nerve growth factor (NGF) is critical in the pathogenesis of allergic airway inflammation in vivo and induces proliferation of airway smooth muscle cells and matrix metalloproteinase-9 (MMP-9) expression in vitro. However, the effects of NGF on chronic pulmonary diseases of allergic origin remain unknown. To investigate the effects of NGF on lung inflammation and airway remodeling, 32 Wistar rats were randomly divided into four groups: control, NGF, ovalbumin (OVA) and anti-rat-β-NGF antibody (anti-NGF). Aerosolized OVA was administered to the rats in the NGF, OVA and anti-NGF groups to generate the asthmatic rat model, and NGF or anti-NGF was administered 3 h prior to OVA inhalation every two days. On day 70, bronchial responsiveness tests, bronchoalveolar lavage (BAL) and cell counting were conducted. The levels of serum OVA-specific immunoglobulin E (IgE) and of T-helper cell type-2 (Th2) cytokines [interleukin (IL)-4 and IL-13] in the BAL fluid were measured by enzyme-linked immunosorbent assay. The expression levels of NGF protein and MMP-9 mRNA, and the activity of MMP-9 in the lungs were detected by western blot analysis, quantitative polymerase chain reaction and gelatin zymography analysis, respectively. Our results showed that NGF significantly increased eosinophilic airway inflammation, persistent airway hyperresponsiveness (AHR), the serum levels of OVA-specific IgE and the levels of Th2 cytokines in the BAL fluid, and also increased the expression levels and activity of MMP-9. However, anti-NGF treatment significantly inhibited eosinophilic airway inflammation, persistent AHR and airway remodeling. The results showed that NGF may have exacerbated the development of airway inflammation, AHR and airway remodeling through a Th2 pathway and by increasing the level of MMP-9 expression. Therefore, anti-NGF is potentially beneficial for preventing and treating patients with asthma.

Abstract
Asthma is characterized by chronic airway inflammation, which induces airway remodelling of the extracellular matrix over time. Matrix metalloproteinases (MMPs) are involved in this process, and single-nucleotide polymorphisms (SNPs) in MMP genes may influence their mRNA expression levels or abilities to bind substrates and inhibitors, thereby contributing to asthma predisposition and severity. MMP-9 is highly expressed in airways and many studies support its involvement in asthma pathogenesis; however the contribution of MMP-9 SNPs is controversial. To investigate whether MMP-9 SNPs are associated with childhood-onset asthma in Mexican patients we conducted a case-control study including 403 children with clinical asthma diagnoses and 426 healthy controls from Mexico. The cases and controls were matched by ethnicity and gender. We found that the SNPs rs2274755, rs17577, and rs3918249 were associated with asthma risk. The most significant associations were with rs2274755 (OR=2.10, 95% CI 1.31-3.39, P=0.001) and rs17577 (OR=2.07, 95% CI 1.29-3.30, P=0.001); which were in strong linkage disequilibrium. Both SNPs were also associated with atopic asthma (OR=2.38, 95% CI 1.44-3 · 96, P=0.0005). The SNP rs3918249 exhibited a female gender-dependent association with asthma (OR=1.66, 95% CI 1.14-2.43, P=0.007). Our results suggest that MMP-9 polymorphisms could play a role in the susceptibility to childhood-onset asthma.
