摘要：
Here, we aimed to explore the therapeutic effect of voluntary wheel running (VWR) in high-fat diet-fed rats on pulmonary tissue injury via the modulation of autophagic response. Thirty-two rats were allocated into four groups; normal diet (Control); VWR; high-fat-diet (HFD), and HFD + VWR. After three months, pathological effect of HFD on pulmonary tissue was investigated. The levels of tumour necrosis factor (TNF)-alpha were detected in the bronchoalveolar lavage fluid (BALF). We monitored the expression of interleukin (IL)-6 and autophagy-related genes in lung tissues. H&E staining showed pathological changes in HFD group coincided with the increase of TNF-alpha levels in the bronchoalveolar fluid compared to the normal rats. Our results showed the up-regulation of IL-6, becline-1, LC3 and P62 in the HFD group compared to the Control group. VWR inhibited HFD-induced changes and could decrease HFD-induced changes via the regulation of autophagy status.
