Background and Purpose.
Metformin, a widely used antidiabetic drug, has been shown to have anti-inflammatory properties; nevertheless, its influence on β-cell meta-inflammation remains unclear.
The following study investigated the effects of metformin on meta-inflammatory in β-cells and whether the underlying mechanisms were associated with the G protein-coupled receptor 40-phospholipase C-inositol 1, 4, 5-trisphosphate (GPR40-PLC-IP3) pathway.
Materials and Methods.
Lipotoxicity-induced β-cells and the high-fat diet-induced obese rat model were used in the study.
Results.
Metformin-reduced lipotoxicity-induced β-cell meta-inflammatory injury was associated with the expression of GPR40.
GPR40 was involved in metformin reversing metabolic inflammation key marker TLR4 activation-mediated β-cell injury.
Furthermore, downstream signaling protein PLC-IP3 of GPR40 was involved in the protective effect of metformin on meta-inflammation, and the above process of metformin was partially regulated by AMPK activity.
In addition, the anti-inflammatory effects of metformin were observed in obese rats.
Conclusion.
Metformin can reduce lipotoxicity-induced meta-inflammation in β-cells through the regulation of the GPR40-PLC-IP3 pathway and partially via the regulation of AMPK activity.
