ABSTRACT
Objective:
To investigate the effect of Lycium barbarum polysaccharides on inflammatory cytokines in type 2 diabetes mellitus (T2DM) mice without myeloid differentiation factor 88 gene (MyD88-/-).Methods:
Levels of interleukin 1β (IL-1β), IL-6, IL-8, transforming growth factor β1 (TGF-β1), and IL-10 in serum were assessed by ELISA in the MyD88-/- T2DM mice which had been administered with different doses of LBP (20, 40, and 80 mg/kg). Mouse macrophages Raw264.7 were stimulated by lipopolysaccharide (LPS) after treatment with different concentrations of LBP (25, 50, and 100 μg/mL). Then Western blotting was used to detect nuclear translocation level of nuclear factor κB (NF-κB) and protein expressions of inhibitor of NF-κB (IκB) and p-IκB.Results:
Serum levels of IL-1β and TGF-β1 in MyD88-/- T2DM mice were down-regulated by LBP (P<0.05). Cell experiment proved that nuclear migration of NF-κB was dose-dependently inhibited by LBP, and the level of p-IκB was reduced by high dose of LBP.Conclusion:
LBP can reduce some proinflammatory cytokines in the MyD88-/- T2DM mice, which may be related with its inhibitive effect on the phosphorylation of IκB and nuclear migration of NF-κB in the macrophages.
