Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Separated and expanded the CD4+CD25+CD127- Tregs from peripheral blood of autoimmune hepatitis patients and administrate the cells (5 x 106 cells/kg) into patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The trial will be carried out in autoimmune patients. The investigators will isolate CD4(cluster of differentiation)+CD25(cluster of differentiation25)+CD127(cluster of differentiation127)- Tregs from these patients, and expand them with IL(interleukin)-2 retinoid acid and anti-CD3(cluster of differentiation 3) /CD28(cluster of differentiation 28) beads. The patients will be subsequently treated with single infusion of CD4+CD25+CD127- Tregs (10-20 x 106 cells/kg).

In the clinical trials, the investigators will monitor the number of Tregs in patients at different periods, and to test their suppressive functions in vitro. Also the function and biopsy of liver will be processed to determine the efficacy of Treg therapy.
