- Airway remodeling is reversed by aerobic training in a murine model of chronic asthma(2015) SILVA, R. A.; ALMEIDA, F. M.; OLIVO, C. R.; SARAIVA-ROMANHOLO, B. M.; MARTINS, M. A.; CARVALHO, C. R. F.The aim of this study was to investigate if the aerobic training (AT) reverses airway remodeling (AR) in an asthma model. BALB/c were divided into four groups: control (unsensitized and untrained); ovalbumin (OVA: sensitized and untrained); AT (unsensitized and trained) and OVA+AT. Allergic inflammation was induced with intraperitoneal and OVA inhalation. AT (low intensity; 5x/week; 60min/session) was performed at 7, 15, and 30 days. Leukocyte counting in the bronchoalveolar lavage fluid; the expression of IL-5, eotaxin, RANTES, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1); AR features (airway smooth muscle, epithelium thickness, collagen and elastic fibers, mucus production); and AR inducers (transforming growing factor-beta, osteopontin, vascular endothelial growth factor). OVA induced an increase in leukocyte airway migration and increased AR features (P<0.05). After 7 days, AT reversed the OVA-induced eosinophil and macrophage airway migration, the expression of IL-5, eotaxin, RANTES, ICAM-1, VCAM-1, and all AR inducers. However, total reversion of the AR features and inducers and airway inflammation occurred only after 15 days of AT compared with the OVA groups (P<0.05) and the effects were maintained until the 30th day. AT reverses AR after 15 days and this effect is preceded by the inhibition of leukocyte migration and occurs simultaneously with the reduction in the expression of inflammatory mediators and AR inducers.
- Comparison of the Effects of Aerobic Conditioning Before and After Pulmonary Allergic Inflammation(2015) SILVA, Ronaldo Aparecido da; ALMEIDA, Francine Maria; OLIVO, Clarice Rosa; SARAIVA-ROMANHOLO, Beatriz Mangueira; PERINI, Adenir; MARTINS, Milton Arruda; CARVALHO, Celso Ricardo FernandesThe aim of this study is to compare the effects of aerobic conditioning (AC) before (ACBS) and after (ACAS) allergic sensitization. BALB/c mice were divided into two main groups: ACBS and ACAS. Each groups was divided into subgroups: control (nonsensitized/nontrained), AC (nonsensitized/trained), ovalbumin (OVA) (sensitized/nontrained), AC + OVA (trained/sensitized), and OVA + AC (sensitized/trained). Sensitization was induced using OVA and AC performed in treadmill (moderate intensity). We examined IgE and IgG(1) levels, eosinophil counting, expression of Th1 (interleukin (IL)-2, IFN-alpha) and Th2 cytokines (IL-4, IL-5, IL-13), IL-10, vascular endothelial growth factor (VEGF), and airway remodeling. IgE and IgG(1) were decreased only when exercise was performed before sensitization (ACBS); however, there was a decrease of eosinophils, Th2 cytokines, VEGF, and airway remodeling and increase in IL-10 in either ACBS or ACAS groups. Our results demonstrate that aerobic conditioning reduces Th2 response before and after sensitization by increasing IL-10 while the production of anaphylactic antibodies is reduced only when exercise is performed before sensitization.
