    Collagenase mRNA Overexpression and Decreased Extracellular Matrix Components Are Early Events in the Pathogenesis of Emphysema
    (2015) ROBERTONI, Fabola S. Z.; OLIVO, Clarice R.; LOURENCO, Juliana D.; GONCALVES, Natalia G.; VELOSA, Ana Paula P.; LIN, Chin J.; FLO, Claudia M.; SARAIVA-ROMANHOLO, Beatriz M.; SASAKI, Sergio D.; MARTINS, Milton A.; TEODORO, Walcy R.; LOPES, Fernanda Degobbi T. Q. S.
    To describe the progression of parenchymal remodeling and metalloproteinases gene expression in earlier stages of emphysema, mice received porcine pancreatic elastase (PPE) instillation and Control groups received saline solution. After PPE instillation (1, 3, 6 hours, 3 and 21 days) we measured the mean linear intercept, the volume proportion of types I and III collagen, elastin, fibrillin and the MMP-1, -8, -12 and -13 gene expression. We observed an initial decrease in type I (at the 3rd day) and type III collagen (from the 6th hour until the 3rd day), in posterior time points in which we detected increased gene expression for MMP-8 and -13 in PPE groups. After 21 days, the type III collagen fibers increased and the type I collagen values returned to similar values compared to control groups. The MMP-12 gene expression was increased in earlier times (3 and 6 hours) to which we detected a reduced proportion of elastin (3 days) in PPE groups, reinforcing the already established importance of MMP-12 in the breakdown of ECM. Such findings will be useful to better elucidate the alterations in ECM components and the importance of not only metalloelastase but also collagenases in earlier emphysema stages, providing new clues to novel therapeutic targets.

    Investigating the Effects of a New Peptide, Derived from the Enterolobium contortisiliquum Proteinase Inhibitor (EcTI), on Inflammation, Remodeling, and Oxidative Stress in an Experimental Mouse Model of Asthma-Chronic Obstructive Pulmonary Disease Overlap (ACO)
    (2023) BARBOSA, Jessica Anastacia Silva; SILVA, Luana Laura Sales da; JOAO, Juliana Morelli Lopes Goncalves; CAMPOS, Elaine Cristina de; FUKUZAKI, Silvia; CAMARGO, Leandro do Nascimento; SANTOS, Tabata Maruyama dos; SANTOS, Henrique Tibucheski dos; BEZERRA, Suellen Karoline Moreira; SARAIVA-ROMANHOLO, Beatriz Mangueira; LOPES, Fernanda Degobbi Tenorio Quirino dos Santos; BONTURI, Camila Ramalho; OLIVA, Maria Luiza Vilela; LEICK, Edna Aparecida; RIGHETTI, Renato Fraga; TIBERIO, Iolanda de Fatima Lopes Calvo
    The synthesized peptide derived from Enterolobium contortisiliquum (pep3-EcTI) has been associated with potent anti-inflammatory and antioxidant effects, and it may be a potential new treatment for asthma-COPD overlap-ACO). Purpose: To investigate the primary sequence effects of pep3-EcTI in an experimental ACO. BALB/c mice were divided into eight groups: SAL (saline), OVA (ovalbumin), ELA (elastase), ACO (ovalbumin + elastase), ACO-pep3-EcTI (treated with inhibitor), ACO-DX (treated with dexamethasone), ACO-DX-pep3-EcTI (treated with dexamethasone and inhibitor), and SAL-pep3-EcTI (saline group treated with inhibitor). We evaluated the hyperresponsiveness to methacholine, exhaled nitric oxide, bronchoalveolar lavage fluid (BALF), mean linear intercept (Lm), inflammatory markers, tumor necrosis factor (TNF-alpha), interferon (IFN)), matrix metalloproteinases (MMPs), growth factor (TGF-beta), collagen fibers, the oxidative stress marker inducible nitric oxide synthase (iNOS), transcription factors, and the signaling pathway NF-kappa B in the airways (AW) and alveolar septa (AS). Statistical analysis was conducted using one-way ANOVA and t-tests, significant when p < 0.05. ACO caused alterations in the airways and alveolar septa. Compared with SAL, ACO-pep3-EcTI reversed the changes in the percentage of resistance of the respiratory system (%Rrs), the elastance of the respiratory system (%Ers), tissue resistance (%Gtis), tissue elastance (%Htis), airway resistance (%Raw), Lm, exhaled nitric oxide (ENO), lymphocytes, IL-4, IL-5, IL-6, IL-10, IL-13, IL-17, TNF-alpha, INF-gamma, MMP-12, transforming growth factor (TGF)-beta, collagen fibers, and iNOS. ACO-DX reversed the changes in %Rrs, %Ers, %Gtis, %Htis, %Raw, total cells, eosinophils, neutrophils, lymphocytes, macrophages, IL-1 beta, IL-6, IL-10, IL-13, IL-17, TNF-alpha, INF-gamma, MMP-12, TGF-beta, collagen fibers, and iNOS. ACO-DX-pep3-EcTI reversed the changes, as was also observed for the pep3-EcTI and the ACO-DX-pep3-EcTI. Significance: The pep3-EcTI was revealed to be a promising strategy for the treatment of ACO, asthma, and COPD.

    Effects of a Peptide Derived from the Primary Sequence of a Kallikrein Inhibitor Isolated from Bauhinia bauhinioides (pep-BbKI) in an Asthma-COPD Overlap (ACO) Model
    (2023) SILVA, Luana Laura Sales da; BARBOSA, Jessica Anastacia Silva; JOAO, Juliana Morelli Lopes Goncalves; FUKUZAKI, Silvia; CAMARGO, Leandro do Nascimento; SANTOS, Tabata Maruyama dos; CAMPOS, Elaine Cristina de; COSTA, Arthur Silva; SARAIVA-ROMANHOLO, Beatriz Mangueira; BEZERRA, Suellen Karoline Moreira; LOPES, Fernanda Tenorio Quirino dos Santos; BONTURI, Camila Ramalho; OLIVA, Maria Luiza Vilela; LEICK, Edna Aparecida; RIGHETTI, Renato Fraga; TIBERIO, Iolanda de Fatima Lopes Calvo
    (1) There are several patients with asthma-COPD overlap (ACO). A peptide derived from the primary sequence of a kallikrein inhibitor isolated from Bauhinia bauhinioides (pep-BbKI) has potent anti-inflammatory and antioxidant effects. Purpose: To investigate the effects of pep-BbKI treatment in an ACO model and compare them with those of corticosteroids. (2) BALB/c mice were divided into groups: SAL (saline), OVA (ovalbumin), ELA (elastase), ACO (ovalbumin + elastase), ACO-pep-BbKI (treated with inhibitor), ACO-DX (dexamethasone treatment), ACO-DX-pep-BbKI (both treatments), and SAL-pep-BbKI (saline group treated with inhibitor). We evaluated: hyperresponsiveness to methacholine, bronchoalveolar lavage fluid (BALF), exhaled nitric oxide (eNO), IL-1 & beta;, IL-4, IL-5, IL-6, IL-10, IL-13, IL-17, IFN-& gamma;, TNF-& alpha;, MMP-9, MMP-12, TGF-& beta;, collagen fibers, iNOS, eNO, linear mean intercept (Lm), and NF-& kappa;B in airways (AW) and alveolar septa (AS). (3) ACO-pep-BbKI reversed ACO alterations and was similar to SAL in all mechanical parameters, Lm, neutrophils, IL-5, IL-10, IL-17, IFN-& gamma;, TNF-& alpha;, MMP-12 (AW), collagen fibers, iNOS (AW), and eNO (p > 0.05). ACO-DX reversed ACO alterations and was similar to SAL in all mechanical parameters, Lm, total cells and differentials, IL-1 & beta;(AS), IL-5 (AS), IL-6 (AS), IL-10 (AS), IL-13 (AS), IFN-& gamma;, MMP-12 (AS), TGF-& beta; (AS), collagen fibers (AW), iNOS, and eNO (p > 0.05). SAL was similar to SAL-pep-BbKI for all comparisons (p > 0.05). (4) Pep-BbKI was similar to dexamethasone in reducing the majority of alterations of this ACO model.

    Low-dose chlorine exposure impairs lung function, inflammation and oxidative stress in mice
    (2021) GENARO, Isabella Santos de; ALMEIDA, Francine Maria de; LOPES, Fernanda Degobbi Tenorio Quirino dos Santos; KUNZLER, Deborah De Camargo Hizume; TRIPODE, Bruna Gabryela Busoletto; KURDEJAK, Adriana; CORDEIRO, Bruna Nakamura; PANDOLPHO, Renata; MACCHIONE, Mariangela; BRUGGEMANN, Thayse Regina; VIEIRA, Rodolfo Paula; MARTINS, Milton Arruda; TIBERIO, Iolanda de Fatima Lopes Calvo; SARAIVA-ROMANHOLO, Beatriz Mangueira
    Aim: To explore the different consequences of acute and chronic exposure to chlorine gas (Cl-2) on the functional and histological parameters of health mice. Main methods: Firstly, male BALB/c mice were acute exposed to 3.3 or 33.3 or 70.5 mg/m(3) Cl-2. We analyzed the lung function, the inflammatory cells in the bronchoalveolar lavage, cell influx in the peribrochoalveolar space and mucus production. In a second phase, mice were chronic exposed to 70.5 mg/m(3) Cl-2. Besides the first phase analyses, we also evaluated the epithelial cells thickness, collagen deposition in the airways, immunohisto-chemistry stain for IL-1 beta, iNOS, IL-17 and ROCK-2 and the levels of IL-5, IL-13, IL-17, IL-1 beta and TNF-alpha in lung homogenate. Key findings: Acute exposure to chlorine impaired the lung function, increased the number of inflammatory cells in the BALF and in the airways, also increased the mucus production. Furthermore, when chlorine was exposed chronically, increased the airway remodeling with collagen deposition and epithelial cells thickness, positive cells for IL-1 beta, iNOS, IL-17 in the airways and in the alveolar walls and ROCK-2 in the alveolar walls, lung inflammation with increased levels of IL-5, IL-13, IL-1 beta and TNF-alpha in the lung homogenate, and also, induced the acid mucus production by the nasal epithelium. Significance: Acute and chronic exposure to low dose of chlorine gas worsens lung function, induces oxidative stress activation and mucus production and contributes to augmenting inflammation in health mice.
