Zusammenfassung: | To evaluate T-helper cytokine responses in a short-term high fat diet (HFD) induced impaired glucose metabolism. To further evaluate the modulation of T-helper 1 (Th1) and T-helper 2 (Th2) cytokines using short-term low-dose aspirin in combination with metformin.
Two experiments were carried out in this study in order to evaluate the T-helper cytokine profiles in a state of impaired glucose metabolism. A total of 28 six-week-old male C57BL/6 mice were used in this study. In the first experiment, mice were fed either a high fat diet or low fat diet for a duration of 10 weeks. We then determined the Th1, Th2 and T-helper 17 (Th17) cytokine profiles. In the second experiment, we evaluated whether the short term 6-week treatment with low-dose aspirin in combination with metformin modulates T-helper cytokine profiles of the HFD-fed mice.
In the first experiment, we measured the body weights, blood glucose levels, insulin levels, lipid profiles and haematological parameters. We further performed oral glucose tolerance testing following an 8-hour fast and serum Th1, Th2 and Th17 cytokine levels were also determined following short-term 8-week diet-feeding and 6-week low-dose aspirin and combined metformin with low-dose aspirin treatment.
High fat diet-feeding caused a marked increase in circulating peripheral blood lymphocytes, which was attenuated by short-term low-dose aspirin treatment. Moreover, the HFD feeding resulted in 2-fold increase in total cholesterol and a 4-fold increase in low-density lipoprotein cholesterol when compared to the low-fat diet-fed group (p 0.05). While the combination of low-dose aspirin with metformin considerably reduced the levels of serum IFN-Ƴ (P |
