Area of Science:

  • Immunology
  • Hepatology
  • Biomarker Discovery

Background:

  • Chronic Hepatitis B Virus (HBV) infection is a primary risk factor for hepatocellular carcinoma.
  • Limited predictive models exist for HBV clearance based on immune biomarkers.

Purpose of the Study:

  • To develop and validate a reliable immune-based predictive model for HBV clearance.
  • To identify key immune biomarkers associated with HBV clearance.
  • To elucidate divergent immune responses in chronic versus resolved HBV infection.

Main Methods:

  • Quantified mRNA expression of CD4+ T-cell transcription factors, cytokines, and immune checkpoints in PBMCs using RT-qPCR.
  • Developed a binary logistic regression model with internal and external validation.
  • Utilized an HBV-transfected mouse model for in vivo validation.

Main Results:

  • Identified GATA3, FOXP3, IFNG, TNF, and HAVCR2 as key predictive genes for HBV clearance.
  • Demonstrated robust predictive accuracy of the developed model.
  • Observed distinct immune gene regulation patterns between chronic and resolved HBV groups.

Conclusions:

  • Established a reliable immune-based predictive model for HBV clearance.
  • Highlighted divergent immune responses differentiating chronic and resolved HBV infections.
  • Provided insights into immunomodulatory mechanisms relevant to HBV pathogenesis.
