Life Sci 2022; 293:120306. [PMID: 35016883 DOI: 10.1016/j.lfs.2022.120306] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2021] [Revised: 01/01/2022] [Accepted: 01/04/2022] [Indexed: 11/27/2022]
Abstract
Recent studies have shown that proper exercise significantly restricts inflammatory responses through regulation of the immune system. This review discusses mechanisms of protective effects of exercise in lipopolysaccharide (LPS)-induced lung injury. We performed a systematic search in PubMed, Scopus, and Web of Sciences using the search components "physical exercise", "lung" and "LPS" to identify preclinical studies, which assessed physical activity effects on LPS-induced pulmonary injury. Articles (n = 1240) were screened and those that had the eligibility criteria were selected for data extraction and critical appraisal. In all of the 21 rodent-model studies included, pulmonary inflammation was induced by LPS. Exercise protocols included low and moderate intensity treadmill training and swimming. The results showed that aerobic exercise would prevent LPS-induced oxidative stress and inflammation as well as airways resistance, exhaled nitric oxide, protein leakage, increase in total WBC, macrophage and neutrophil population, levels of interleukin (IL)-6, IL-1β, IL-17, tumor necrosis factor-α, granulocyte-macrophage colony-stimulating factor and CXCL1/KC, and improved IL-10 and IL-ra in lung tissue, bronchoalveolar lavage fluid (BALF) and serum. In addition, in trained animals, the expression of some anti-inflammatory factors such as heat shock protein72, IL-10, triggering receptor expressed on myeloid cells-2 and irisin was increased, thus ameliorating lung injury complications. Aerobic exercise was shown to alleviate the LPS-induced lung injury in rodent models by suppressing oxidative stress and lowering the ratio of pro-inflammatory to anti-inflammatory cytokines.

Maruoka H, Tanaka KI, Takayanagi M, Zenda M. Effects of neuromuscular electrical stimulation on pulmonary alveola and cytokines in chronic obstructive pulmonary disease (COPD) and skeletal muscle atrophy model mice. J Phys Ther Sci 2021; 33:1-8. [PMID: 33519066 PMCID: PMC7829565 DOI: 10.1589/jpts.33.1] [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: 08/13/2020] [Accepted: 10/02/2020] [Indexed: 11/24/2022] Open
Abstract
[Purpose] It has been reported that exercise affects skeletal muscle in the chronic obstructive pulmonary disease (COPD) disease model. In this study, we examined the effects of neuromuscular electrical stimulation (NMES) in skeletal muscle on alveoli and cytokines. [Materials and Methods] We used twenty wild-type mice, randomly divided into three groups: Group A: Control (non-COPD, non-amyotrophia, non-NMES), Group B: COPD, amyotrophia with NMES and Group C: COPD, amyotrophia without NMES. Among those, a group of mice with ages from 12 to 14 weeks were used to create a chronic obstructive pulmonary disease (COPD) model, a group of mice with ages from 15 to 16 weeks was used to create a disuse syndrome by hind limb suspension, and a group of mice with ages from 17 to 28 weeks (12 weeks) were used to implement NMES. In this study, we used the real-time PCR method to assess the mRNA expression levels. We also conducted morphological analysis, assessed macrophage expression level by staining (general staining and immunostaining), and employed spirometry. [Results] Our study results showed significant decreases in Interleukin-6 (IL-6) levels in the lungs and muscle RING-finger protein-1 (MuRF1) in the muscles. Moreover, the pulmonary stromal macrophage marker (F4/80) and the protease marker (MMP12) showed significantly decreased expression, while no change was observed in the morphological of the alveolar spaces (mean linear intercept). [Conclusion] On the basis of these findings, our study reveals that NMES affects cytokines and macrophages in COPD skeletal muscle atrophy.

Muscle metabolomics analysis reveals potential biomarkers of exercise‑dependent improvement of the diaphragm function in chronic obstructive pulmonary disease. Int J Mol Med 2020; 45:1644-1660. [PMID: 32186768 PMCID: PMC7169662 DOI: 10.3892/ijmm.2020.4537] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Accepted: 02/17/2020] [Indexed: 12/25/2022] Open
Abstract
Decreased diaphragm function is a crucial factor leading to reduced ventilatory efficiency and worsening of quality of life in chronic obstructive pulmonary disease (COPD). Exercise training has been demonstrated to effectively improve the function of the diaphragm. However, the mechanism of this process has not been identified. The emergence of metabolomics has allowed the exploration of new ideas. The present study aimed to analyze the potential biomarkers of exercise-dependent enhancement of diaphragm function in COPD using metabolomics. Sprague Dawley rats were divided into three groups: COPD + exercise group (CEG); COPD model group (CMG); and control group (CG). The first two groups were exposed to cigarette smoke for 16 weeks to establish a COPD model. Then, the rats in the CEG underwent aerobic exercise training for 9 weeks. Following confirmation that exercise effectively improved the diaphragm function, a gas chromatography tandem time-of-flight mass spectrometry analysis system was used to detect the differential metabolites and associated pathways in the diaphragm muscles of the different groups. Following exercise intervention, the pulmonary function and diaphragm contractility of the CEG rats were significantly improved compared with those of the CMG rats. A total of 36 different metabolites were identified in the comparison between the CMG and the CG. Pathway enrichment analysis indicated that these different metabolites were involved in 17 pathways. A total of 29 different metabolites were identified in the comparison between the CMG and the CEG, which are involved in 14 pathways. Candidate biomarkers were selected, and the pathways analysis of these metabolites demonstrated that 2 types of metabolic pathways, the nicotinic acid and nicotinamide metabolism and arginine and proline metabolism pathways, were associated with exercise-induced pulmonary rehabilitation.
