T cells are major players in chronic inflammatory diseases such as autoimmune hepatitis (AIH). However, it is not clear which subset of T cells participates in the pathophysiology of the disease. The aim of this study was to assess the expression profile of signature transcription factor and cytokines of T helper 17 (Th17) cells in patients with AIH.

A total of 24 patients with AIH and 24 normal subjects were recruited in the study. Comparison of gene expression patterns between the patients and normal subjects was done by quantitative real-time reverse transcriptase polymerase chain reaction (qRT-PCR).

The results showed that retinoic acid receptor-related orphan receptors gamma (RORɣt), interleukin-17A (IL-17A), and interleukin-22 (IL-22) mRNA expression were increased greatly in the patients group compared with the normal controls group (p < 0.05).

Deregulated production of Th17-related molecules may be associated with the pathogenesis of AIH.
