Abstract
BACKGROUND
This study aimed at establishing the autoimmune hepatitis (AIH) model of C57BL/6 mice, and examining the expression and significance of T follicular helper (Tfh) cells, T follicular regulatory (Tfr) cells, effector B cells and other indicators in this experimental autoimmune hepatitis (EAH) model.
METHODS
C57BL/6 mice in experimental group were administered by intraperitoneal injection after fully emulsified on 1st day and 7th day with 0.5 mL of 0.5-2.0 g/L S-100 and an equal volume of Buddha Complete Adjuvant (CFA). The levels of serum alanine transaminase (ALT), aspartate aminotransferase (AST), and interleukin-21 (IL-21) were tested by the corresponding kit. Tfr, Tfh and B cell subsets were quantified by flow cytometry. Histological pathology was completed by pathological section experiments.
RESULTS
In comparison with that in the healthy controls (HC), significantly increased numbers of serum ALT and AST, Tfr, IL-21 was observed. The hepatic lobules and hepatocyte cords were severely disorganized.
CONCLUSION
The results of liver pathological changes and serum index changes were similar to the chronic and progressive pathogenesis and pathology of AIH patients, providing a detailed pathological basis for the basic research and clinical experiments of AIH.
