Abstract
Objective: The purpose of this study was to investigate the effects of 8 weeks of high-intensity interval training (HIIT) and vitamin D3 supplementation on Chemokine (C-C motif) Ligand 5 (CCL-5) and C-C motif chemokine receptor 5 (CCR5) in the white adipose tissue (WAT) of male rats with type 2 diabetes (T2DM).
Materials and methods: The experimental study involved 40 male Wistar rats divided into 5 groups (n=8). These groups were healthy control (HC), diabetic control (DC), diabetic+HIIT (DHIIT), diabetic+vitamin D3 (DD3), and diabetic+HIIT+vitamin D3 (DHIITD3). The rats completed 8 weeks of HIIT, consisting of 12 sessions lasting 1 minute each at an intensity of 90-95% of their maximum running speed. Additionally, the rats were administered a weekly dose of 10,000 IU/kg of vitamin D3 for 8 weeks.
Results: The levels of CCL-5 (P<0.001) and CCR5 (P=0.003) were found to be higher in the DC group as compared to the HC group. However, when HIIT training and vitamin D3 were administered together, there was a decrease in CCL-5 (P=0.001) and CCR5 (P<0.001) in the DHIITD3 group (P=0.001). Similarly, vitamin D3 alone reduced CCR5 levels in the DD3 group (P< 0.001). Also, the decrease of CCR5 in the DD3 group was higher than in the DHIIT group (P=0.022), and the DHIITD3 group was higher than in the DHIIT group (P<0.001), but there was no difference between the DD3 and DHIITD3 groups (P≥0.05).
Conclusion: The results indicate that combining HIIT training with vitamin D3 has a greater effect on reducing the expression of CCL-5 and CCR5 in the white adipose tissue of rats with type 2 diabetes induced by streptozotocin (STZ) and a high-fat diet (HFD), compared to the effects of each one alone. It is recommended that the study be conducted by measuring the variables involved in the mechanisms and the changes in CCL-5 and CCR5.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
