Summary

This is a retrospective observational study in liver transplantation recipients with or without allograft liver fibrosis. Based on the GM-seq and Tcr-Seq data, a novel diagnostic model including DNA-methylation and TCR-Seq biomarkers will be established.

Detailed description

This is a retrospective study on 60 patients who had previously received liver transplantation in our hospital. The patients will be stratified according to age, including 20 children and 20 adults with allograft liver fibrosis after liver transplantation, while 10 children and 10 adults with fibrosis, respectively. 1. The differential analysis of DNA-methylation will be performed between the allograft liver fibrosis cohort and the control cohort based on the GM-seq sequencing data. And the fibrosis-specific DNA-methylation CpG sites or regions in liver and peripheral blood will be explored in the liver transplantation recipients. 2. The abundance and diversity of TCR between the allograft liver fibrosis cohort and the control cohort will be analyzed. And the fibrosis-specific TCR sequence of allograft liver fibrosis will be screened based on TCR-Seq sequencing and tNGS. 3. The characteristics of DNA-methylation and TCR-Seq biomarkers in allograft liver fibrosis population will be defined. And the similarities and differences of the characteristics between children and adults will be explored. 4. Based on the GM-seq and Tcr-Seq data, a novel diagnostic model including DNA-methylation and TCR-Seq biomarkers will be established.
