Chinese Medicine Bu Xu Hua Yu Recipe for the Regulation of TregTh17 Ratio Imbalance in Autoimmune Hepatitis

الملخص EN

Objectives.

The aim of this study is researching the role of the Regulatory T cell (Treg)/T helper cell-17 (Th17) cell ratio imbalance in the pathogenesis of autoimmune hepatitis (AIH) and the use of the “Bu Xu Hua Yu” recipe in the treatment of AIH.

Materials and Methods.

Sixty adult male C57/BL6 mice were divided into six different groups.

α-Galcer was injected abdominally for production of the animal models.

Liver function tests, histological examinations, liver tissue Regulatory T cell, and T helper cell-17 levels tests were carried out.

TGF-β1, IL-10, IL-17, and expression of mRNA and protein levels of Foxp3 and ROR-γt were also assessed.

Results.

Bu Xu Hua Yu method increased the levels of Regulatory T cell, IL-10, and the expression of Foxp3 ( P < 0.05 ) in mice liver tissues.

Furthermore, there were decreases in the levels of T helper cell-17, IL-17, and expression of RORγt mRNA and protein ( P < 0.05 ).

The ratio of Treg/Th17 was increased ( P < 0.05 ).

Conclusion.

Mice with AIH have a Treg/Th17 ratio imbalance.

Bu Xu Hua Yu method was able to restore the cellular balance of Treg/Th17 through the regulation of the expression of RORγt and Foxp3 and can play an important role in the treatment of AIH.
