Immunobiology and pathogenesis of hepatitis B virus infection

Abstract

Hepatitis B virus (HBV) is a non-cytopathic, hepatotropic virus with the potential to cause a persistent infection, ultimately leading to cirrhosis and hepatocellular carcinoma. Over the past four decades, the basic principles of HBV gene expression and replication as well as the viral and host determinants governing infection outcome have been largely uncovered. Whereas HBV appears to induce little or no innate immune activation, the adaptive immune response mediates both viral clearance as well as liver disease. Here, we review our current knowledge on the immunobiology and pathogenesis of HBV infection, focusing in particular on the role of CD8+ T cells and on several recent breakthroughs that challenge current dogmas. For example, we now trust that HBV integration into the host genome often serves as a relevant source of hepatitis B surface antigen (HBsAg) expression during chronic infection, possibly triggering dysfunctional T cell responses and favouring detrimental immunopathology. Further, the unique haemodynamics and anatomy of the liver — and the changes they frequently endure during disease progression to liver fibrosis and cirrhosis — profoundly influence T cell priming, differentiation and function. We also discuss why therapeutic approaches that limit the intrahepatic inflammatory processes triggered by HBV-specific T cells might be surprisingly beneficial for patients with chronic infection.

Glossary

Cirrhosis

The final stage of fibrosis in which fibrous septa surrounding nodules of regenerating hepatocytes induce profound architectural distortion of the liver and functional insufficiency.

Cross-priming

A functional outcome of cross-presentation (the presentation of extracellular antigens on MHC class I molecules), whereby antigen-specific naive CD8+ T cells are activated by antigen-presenting cells to become effector cells.

Checkpoint inhibitor therapy

A form of cancer immunotherapy targeting immune checkpoints (for example, PD1, CTLA4).

SSB/La-dependent mechanism

T cell-induced cytokines such as IFNγ and TNF have been shown to induce the post-transcriptional downregulation of hepatitis B virus (HBV) RNAs in vivo. This process appears to rely on the degradation of the full-length SSB/La protein, which normally functions as a HBV RNA stabilizer in the nucleus of the hepatocyte.

sALT values

The serum concentrations of the liver enzyme alanine aminotransferase. Commonly measured clinically as a biomarker for liver damage.

Space of Disse

(Also referred to as perisinusoidal space). The space that lies between the hepatocytes and the sinusoids.
