Type 1 diabetes is a chronic autoimmune disease of beta cells in the islets of Langerhans, which are responsible for making insulin. Even with insulin therapy, inflammatory complications will develop in the long term.
The present study examines changes in serum levels of interleukin (IL)-6, IL-17, IL-10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, C-peptide, Insulin as well as fasting blood sugar (FBS) in control, diabetic and diabetic treated with curcumin groups. Thirty inbred C57BL /6 mice were randomly divided into three groups of 10 mice: group A consisted of healthy mice receiving citrate buffer, group B included a group of diabetic mice, and group C was a group of diabetic mice treated with curcumin. The cytokine levels were measured in the supernatant of stimulated splenocytes using enzyme -linked immunosorbent assay (ELISA). Radioimmunoassay was used to measure insulin and c-peptide levels. The FBS was measured by an automatic glucometer device.
The levels of IL-6, IL-17, and IFN-γ, as well as FBS, was significantly decreased in the treated group with curcumin compared to the diabetic group mice (p<0.05). TNF-α levels were also low, but the difference was not significant. IL-10, plasma C-peptide, and insulin significantly increased in the supernatant of stimulated splenocytes of treated diabetic group than in the diabetic group (p<0/05).
According to the results, this study supports the anti-diabetic and anti-inflammatory effects of curcumin; however, more studies are needed to investigate theeffects of curcumin and the dose-response relationship in this disease.
