Background and objectives: Inflammation plays a major role in the development and progression of diabetes. Vitamin D deficiency and physical inactivity can also increase the risk of developing type 2 diabetes. Combined therapeutic strategies are promising approaches for the treatment and prevention of diabetes. The aim of this study was to investigate effects of resistance training, vitamin D3 supplementation and adipose-derived mesenchymal stem cell (MSC) transplantation on tumor necrosis factor-beta level in the cerebral cortex of diabetic rats.
Methods: Eighty male Wistar rats (weighing 290±19 g) were randomly divided in to 10 groups: healthy control, sham, diabetes, training, vitamin D, MSC, training+vitamin D, MSC+training, MSC+vitamin D and training+MSC+vitamin D. Training groups were subjected to a resistance training program on ladder. MSC groups received 1.5 × 106 MSCs and vitamin D supplementation groups received 1 microgram/kilogram vitamin D3 eight times. Cortical TNF-β level and fasting serum glucose levels were measured.
Results: After 6 weeks, the combination of resistance training with vitamin D3 supplementation and MSC transplantation (P=0.018) as well as the combination of resistance training with MSCs (P=0.024) significantly reduced diabetes-induced elevation of TNF-β level.
Conclusion: Resistance training with appropriate intensity, duration and recovery between exercise sessions, combined with MSC transplantation and vitamin D3 supplementation has profound anti-inflammatory effects on the cerebral cortex tissue of diabetic rats. This type of intervention, especially the transplantation of MSCs, may be a promising protective strategy against some complications of diabetes.
