Abstract:
Objective To explore the effects of Buzhong Yiqi Decoction on PKCβ/Erk1/2/NF-κB signaling pathway in mice with autoimmune thyroiditis(AIT);To explore the mechanism of Buzhong Yiqi Decoction in the treatment of AIT.Methods Totally 808-week-old NOD.H-2h4 mice were randomly divided into control group,model group,TCM group and selenium yeast tablet group,with 20 mice in each group.The control group was fed with distilled water,and the other groups were given 0.05%sodium iodide for 8 weeks to establish AIT mice model.The medication groups were administered by gavage with corresponding drugs for 8 weeks.The morphology of thyroid tissue was detected by HE staining,ELISA was used to detected the contents of serum TGAb and TPOAb,RT-qPCR was used to detect the expression of PKCβ,Erk1/2,NF-κBp65,RORγt and IL-17 mRNA in thyroid tissue,the protein expressions of PKCβ,Erk1/2,NF-κBp65,RORγt and IL-17 in thyroid tissue were detected by Western blot.Results Compared with the control group,there were a large number of lymphocyte infiltration in thyroid tissue,and serum TGAb and TPOAb contents significantly increased(P<0.001),the expression of PKCβ,Erk1/2,NF-κBp65,RORγt and IL-17 mRNA and protein in thyroid tissue were significantly increased(P<0.001).Compared with the model group,the infiltration of lymphocytes in thyroid tissue of mice in TCM group and selenium yeast tablet group were alleviated,the contents of serum TGAb and TPOAb were significantly decreased(P<0.001),the mRNA and protein expressions of PKCβ,Erk1/2,NF-κBp65,RORγt and IL-17 in thyroid tissue were significantly decreased(P<0.001).There was no statistical significance in the indexes of TCM group and selenium yeast tablet group(P>0.05).Conclusion Buzhong Yiqi Decoction can regulate PKCβ/Erk1/2/NF-κB pathway,reduce inflammation in AIT mice and improve thyroid lymphocyte infiltration.
