Chronic liver diseases are caused by continuous or repeated damage to the liver, leading to fibrosis and cirrhosis, representing inflammatory and scarring processes, respectively. A variety of etiologies, such as viral infection, toxin exposure, alcohol abuse, metabolic and genetic diseases are associated with persistent liver injury, harbouring the risk for hepatocellular carcinogenesis.

Our team has developed an all-in-one liver cell preparation technique from human tissue, allowing analysis of cell type-specific, liver-specific and disease-specific aspects on cellular and molecular levels. The parenchymal and non-parenchymal cells of the liver are part of the innate immune system. They express evolutionarily highly conserved inheritable factors called pathogen recognition receptors (PRRs). They recognize molecular patterns of viruses, bacteria, fungi and parasites that are absent in higher organisms. However, damage associated molecular pattern are recognized as well, suggesting a vital role in chronic liver diseases. The PRR represent one of the first lines of defence against invading pathogens and mediate a coordinated immune response through the expression of inflammatory cytokines, antiviral factors, and chemotactic agents. Disease-related imbalance of the hepatic immune system affects I) growth and regeneration controlled by Hippo signalling pathway, II) functions of the endoplasmic reticulum and Golgi apparatus and III) autophagy and vesicular transport. The major goal of our research is to reveal pathophysiological processes at the molecular level in order to monitor the progression of chronic liver diseases and improve therapies.

... the influence of parenchymal and non-parenchymal liver cells on hepatitis B virus infection and how virus-host interactions determine immunopathology and chronicity.

... the role of HBe and HBs antigens in evading endogenous innate immune responses using models of hepatitis B virus infection.

... how HBs antigen induces stress in the endoplasmic reticulum, impairs autophagy processes, and promotes proliferation and hepatocarcinogenesis.

... multimolecular therapeutic strategies against copper overload in Wilson disease (WilsonMed).

... the effects of Wilson disease on innate signaling, Hippo pathway activity, and intracellular transport in a cell culture model.
