Abstract
Background: Cytokines are immune related factors. Production of pro inflammatory cytokines in diabetic patients is increased, which is exacerbated by vigorous training. This study investigates the response of serum IL-2 and IL-4 to eight-week high Intensity Interval Training (HIIT) with caffeine intake on inflammatory and anti-inflammatory responses in diabetic rats.
Methods: In a clinical-interventional animal study, 50 male rats were randomly assigned to 5 equal groups (control group (C), diabetes group (D), diabetes + caffeine group (D+Ca), diabetes + training group (D+T), diabetes + training + caffeine group (D+Ca+T)) and subjected to 8 weeks of caffeine supplementation (70 mg / kg of caffeine powder was injected five days each week) and 8 weeks of 5 sessions per week with 6 to 12 times, 2-min intervals with intensity of 85-90% of maximal speed. 48 hours after the last training session, immunological factors including IL-2 and IL-4 were measured. Statistical analysis of variables was performed using One-way ANOVA and Tukey tests at the significant level (P<0.05).
Results: The results showed that (D+Ca) group had the lowest IL2 in comparison with (D) group (P= 0.001). IL-4 had the highest in (D+Ca) and (D+Ca+T) groups (P = 0.001). But these differences were not statistically significant between (D+Ca) and (D+Ca+T) groups (P= 0.67).
Conclusion: It seems that caffeine to play a role in improving the status of IL-2 and IL-4 in streptozotocin-induced diabetes, but HIIT exercises are not effective in this regard.

Abstract
Background: In this study, the effect of oral administration of recombinant human interleukin-2 (rhIL-2) on brain NO level and AChE activity in hyperglycemic conditions induced by high-sucrose diet (HSD), as a type-2 diabetes model, was investigated in Drosophila melanogaster.
Methods: In this experimental research, adult fruit flies of both sexes (30 in each group) were divided into the six groups: receiving normal diet (ND); high-sucrose diet (HSD); ND with rhIL-2 at 0.01 and 0.1 ng/ml; and HSD with rhIL-2 at 0.01 and 0.1 ng/ml. Flies were bred on these culture media for three weeks. At the end of the experiments, the brains of the flies were extracted, homogenized, and glucose, NO, and AChE activity levels were measured by the kit.
Results: Glucose level, AChE activity and NO level increased in brain homogenate of HFD flies compared to ND group. The body weight of HSD flies was reduced compared to the ND. Administration of rhIL-2 along with HFD significantly prevented these changes.
Conclusion: These findings suggest that rhIL-2 partially prevents diabetic neuropathy in Drosophila. It seems that the preventive effects of this compound are mediated through mechanisms dependent on nitric oxide and acetylcholinesterase in the brain.
