Abstract
BACKGROUND Pulmonary fibrosis is a pathological hallmark of lung injury. It is an aggressive disease that replaces normal lung parenchyma by fibrotic tissue. The transforming growth factor-beta-mothers against decapentaplegic homolog 3 (TGF-β1-Smad3) signaling pathway plays a key role in regulating lung fibrosis. Decorin (DCN), a small leucine-rich proteoglycan, has a modulatory effect on the immune system by reversibly binding with TGF-β and reducing its bioavailability. Mesenchymal stem cell (MSC) therapy is a new strategy that has an immune-modulatory capacity. OBJECTIVE The aim of this study was to introduce a new therapeutic approach to harness remodeling in injured lung. MATERIAL AND METHODS Bone marrow MSCs were isolated and transduced by decorin gene. Lung injury was induced by bleomycin and mice were treated with MSCs, MSCs-decorin, and decorin. Then, oxidative stress biomarkers, remodeling biomarkers, bronchoalveolar lavage cells, and histopathology study were conducted. RESULTS Reduced catalase and superoxide dismutase increased due to treatments. Elevated malondialdehyde, hydroxyproline, TGF-β levels, and polymorphonuclear cells count decreased in the treated groups. Additionally, the histopathology of lung tissues showed controlled inflammation and fibrosis. CONCLUSION Transfected decorin gene to MSCs and used cell therapy could control remodeling and bleomycin-induced lung injury.

Abstract
Asthma is a complex respiratory disease, which is controlled by genetic and environmental factors. Type 2-dominant immune response is responsible for asthma. Decorin (Dcn) and stem cells have modulatory effect on immune system and may control tissue remodeling and asthma pathophysiology. In this study, immunomodulatory effect of transduced induced pluripotent stem cells (iPSCs) with expression of Dcn gene on allergic asthma pathophysiology was evaluated. After transduction of iPSCs with Dcn gene, allergic asthma mice were treated with iPSCs and transduced iPSCs via intrabronchial. Then, airway hyperresponsiveness (AHR), levels of interleukin (IL)-4, IL-5, IL-13, IL-33, total IgE, leukotrienes (LTs) B4, C4, hydroxyproline (HP) content, and transforming growth factor-beta (TGF-β) were measured. Also, lung histopathology study was done. AHR, levels of IL-4, IL-5, IL-13, IL-33, total IgE, LTs B4, C4, TGF-β, HP content, mucus secretion, goblet cell hyperplasia, and eosinophilic inflammation were controlled by iPSCs and transduced iPSCs treatment. Therapeutic effect of iPSCs could control main allergic asthma symptoms and related pathophysiologic mechanisms and the effect can be increased when applied with Dcn expression gene.

Abstract
BACKGROUND AND OBJECTIVE Decorin (Dcn), an extracellular matrix proteoglycan, has several important biological functions, and its deposition is altered in the airway wall of humans with asthma and animal models of asthma. Due to its high affinity for transforming growth factor beta (TGF)-β, Dcn can function as part of a negative feedback mechanism, resulting in the regulation of this factor's bioavailability. Dcn deficient (Dcn(-/-) ) mice develop reduced airway inflammation, hyperresponsiveness and remodeling in response to repeated allergen challenge; we investigated whether regulatory T cells play a role in the diminished airway response of Dcn(-/-) mice. METHODS Dcn(-/-) and Dcn(+/+) mice (C57Bl/6) were sensitized with ovalbumin (OVA) and challenged intra-nasally 3 days/week × 3 weeks. After allergen challenge, bronchoalveolar lavage was collected to quantify total and differential cell counts and cytokine levels. Inflammatory cell number and cytokine messenger ribonucleic acid (mRNA) production were assessed in lung tissues. Cells from lung and spleen were extracted to evaluate regulatory T cells. RESULTS Tissue inflammation and interleukin (IL)-13 mRNA expression were significantly increased in OVA-challenged Dcn(+/+) mice, only. The increased expression of Foxp3 in CD4(+) CD25(+) T cells found in lung of OVA-challenged Dcn(-/-) mice was accompanied by an increase in IL-10 mRNA. CONCLUSIONS Our data demonstrated that a diminished lung inflammation in OVA challenged Dcn(-/-) mice was accompanied by a higher expression of regulatory T cells and IL-10 mRNA levels. These results reinforce the importance of Dcn in biological processes, particularly in an allergic model of asthma.

Abstract
BACKGROUND AND OBJECTIVES Airway remodeling is a main feature of asthma. Different biological phenotypes of severe asthma have been recently recognized by the ENFUMOSA study group and among these one is characterized by neutrophilic airway inflammation. Concentrations of MMP-9 in airways have been suggested as a marker to monitor airway remodeling in asthma. OBJECTIVE The aim of the present study was to explore airway remodeling in different biological phenotypes of asthma by measuring MMP-9 in EBC and correlating these with other variables. METHODS Sixty consecutive subjects with asthma and 20 healthy controls were enrolled in the study. Exhaled MMP-9, pH and NO levels and inflammatory cells in sputum were measured in all subjects enrolled. RESULTS We observed an increase of exhaled MMP-9 in asthmatic subjects compared to controls. Higher exhaled MMP-9 concentrations were described in severe asthmatics compared to mild to moderate especially in those with neutrophilic airway inflammation. We further found a correlation between exhaled MMP-9 and percentage of neutrophils in sputum, FEV1, exhaled NO and pH. CONCLUSION Our results seem to substantiate the feasibility of measuring exhaled MMP-9 in the breath of asthmatic patients. MMP-9 may be considered a proxy of the amount of the ongoing airway remodeling in asthma. MMP-9 has been shown to be differentially released in different phenotypes of asthma. The measure of exhaled MMP-9 could help to monitor the ongoing airway remodeling, recognize severe stages of asthma, and possibly help determine the appropriate choice of therapy.

Abstract
The forced oscillation technique (FOT) is a powerful, integrative and translational tool permitting the experimental assessment of lung function in mice in a comprehensive, detailed, precise and reproducible manner. It provides measurements of respiratory system mechanics through the analysis of pressure and volume signals acquired in reaction to predefined, small amplitude, oscillatory airflow waveforms, which are typically applied at the subject's airway opening. The present protocol details the steps required to adequately execute forced oscillation measurements in mice using a computer-controlled piston ventilator (flexiVent; SCIREQ Inc, Montreal, Qc, Canada). The description is divided into four parts: preparatory steps, mechanical ventilation, lung function measurements, and data analysis. It also includes details of how to assess airway responsiveness to inhaled methacholine in anesthetized mice, a common application of this technique which also extends to other outcomes and various lung pathologies. Measurements obtained in naïve mice as well as from an oxidative-stress driven model of airway damage are presented to illustrate how this tool can contribute to a better characterization and understanding of studied physiological changes or disease models as well as to applications in new research areas.

Abstract
Decorin (Dcn) is an extracellular matrix proteoglycan, which affects airway mechanics, airway-parenchymal interdependence, airway smooth muscle proliferation and apoptosis, and transforming growth factor-β bioavailability. As Dcn deposition is differentially altered in asthma, we questioned whether Dcn deficiency would impact the development of allergen-induced asthma in a mouse model. Dcn(-/-) and Dcn(+/+) mice (C57Bl/6) were sensitized with ovalbumin (OA) and challenged intranasally 3 days/wk × 3 wk. After OA challenge, mice were anesthetized, and respiratory mechanics measured under baseline conditions and after delivery of increasing concentrations of methacholine aerosol. Complex impedance was partitioned into airway resistance and tissue elastance and damping. Bronchoalveolar lavage was performed. Lungs were excised, and tissue sections evaluated for inflammatory cell influx, α-smooth muscle actin, collagen, biglycan, and Dcn deposition. Changes in TH-2 cytokine mRNA and protein were also measured. Airway resistance was increased in OA-challenged Dcn(+/+) mice only (P < 0.05), whereas tissue elastance and damping were increased in both OA-challenged Dcn(+/+) and Dcn(-/-), but more so in Dcn(+/+) mice (P < 0.001). Inflammation and collagen staining within the airway wall were increased with OA in Dcn(+/+) only (P < 0.001 and P < 0.01, respectively, vs. saline). IL-5 and IL-13 mRNA were increased in lung tissue of OA-challenged Dcn(+/+) mice. Dcn deficiency resulted in more modest OA-induced hyperresponsiveness, evident at the level of the central airways and distal lung. Differences in physiology were accompanied by differences in inflammation and remodeling. These findings may be, in part, due to the well-described ability of Dcn to bind transforming growth factor-β and render it less bioavailable.

Abstract
The small leucine-rich proteoglycans (SLRPs) are involved in many aspects of mammalian biology, both in health and disease. They are now being recognized as key signaling molecules with an expanding repertoire of molecular interactions affecting not only growth factors, but also various receptors involved in controlling cell growth, morphogenesis and immunity. The complexity of SLRP signaling and the multitude of affected signaling pathways can be reconciled with a hierarchical affinity-based interaction of various SLRPs in a cell- and tissue-specific context. Here, we review this interacting network, describe new relationships of the SLRPs with tyrosine kinase and Toll-like receptors and critically assess their roles in cancer and innate immunity.

Abstract
Allergic inflammation is known to cause airway hyperresponsiveness in mice. However, it is not known whether inflammation affects the stiffness of the airway wall, which would alter the load against which the circumscribing smooth muscle shortens when activated. Accordingly, we measured the time course of airway resistance immediately following intravenous methacholine injection in acutely and chronically allergically inflamed mice. We estimated the effective stiffness of the airway wall in these animals by fitting to the airway resistance profiles a computational model of a dynamically narrowing airway embedded in elastic parenchyma. Effective airway wall stiffness was estimated from the model fit and was found not to change from control in either the acute or chronic inflammatory groups. However, the acutely inflamed mice were hyperresponsive compared with controls, which we interpret as reflecting increased delivery of methacholine to the airway smooth muscle through a leaky pulmonary endothelium. These results support the notion that acutely inflamed BALB/c mice represent an animal model of functionally normal airway smooth muscle in a transiently abnormal lung.
