Despite having great regenerative capacity, the liver fails to regenerate during chronic liver disease due to impaired hepatocyte proliferation. Currently, there are no specific drugs available to treat chronic liver diseases such as non-alcoholic fatty liver disease (NAFLD) and liver transplantation remains the only effective treatment for terminal liver failure, however, this is limited by the availability of donor organs. It is crucial to understand the process of liver regeneration during chronic liver injury to tackle the epidemic of chronic liver diseases. The understanding of key regulators that promote liver regeneration will lead to new interventions for regenerating damaged liver tissue, thus helping to tackle the global problem of chronic diseases. These mechanistic insights also complement ongoing translational studies with aims to provide more efficient regenerative therapies.

My previous studies discovered that bile duct cells called cholangiocytes can become stem cells in the liver and differentiate into hepatocytes, thus revealing novel regenerative pathways and opportunities to promote liver regeneration by modulating the fate of liver stem cells.  During chronic liver injury or extensive hepatocyte damage, compensatory remodelling of bile ducts known as the ductular reaction (DR) occurs. CD4+ lymphocytes infiltrate the liver and predominantly localise to the bile ducts during DR and an imbalance of lymphocyte populations are observed in liver diseases such as NAFLD. We set to investigate the interactions between CD4+ T-cells and cholangiocytes during liver regeneration.

These studies will provide a better understanding of the role of lymphocytes in affecting epithelial regeneration during chronic liver injury and reveal how lymphocytes interacts with the liver epithelium. In conjunction, these will provide new opportunities of promoting liver regeneration through immunomodulation, combining the research areas of immunology and regenerative medicine.

Research Overview

Immune-epithelial interaction during tissue regeneration

The liver is an organ which can exert cellular plasticity upon injury. When the main regenerative mechanism is impaired, fully differentiated cells can convert into other cell type with different functions as a compensatory regenerative mechanism. During this regenerative process, immune cells such as macrophages and lymphocytes infiltrate the liver in a well-coordinated manner. We use rodent models of liver injury and clinical samples to understanding how T lymphocytes communicate with the epithelium during regenerative process and the importance of T lymphocytes in maintaining the balance between complete regeneration and tissue repair.

Role of T regulatory cells in Primary Sclerosing Cholangitis

Primary Sclerosing Cholangitis (PSC) is a disease affecting the bile ducts, causing obstructive flow of bile into the intestines. PSC is characterised by increased inflammation, scarring and reduced bile duct regeneration. The pathogenesis of PSC is poorly understood but has been suggested to be immune mediated. T regulatory cells (Tregs), a cell type specialized in controlling immune response play an important role in the pathogenesis of autoimmune liver disease such as PSC. We aim to investigate the dynamics and functions of Treg populations during PSC to understand the role of Treg in PSC disease progression and identify targets for potential treatments. We aim to use murine and in vitro models to complement human PSC research.

Biographical Profile

Wei-Yu graduated from the University of Edinburgh with a degree in Medical Sciences in 2010. With the gracious support from the Edinburgh University Overseas Research Scholarship and the Charles Darwin Scholarship, he did his PhD training at the Centre for Inflammation Research, University of Edinburgh, where he looked at the possibility of using liver progenitor cells for cellular therapy. Wei-Yu did his postdoctoral training at the Scottish Centre for Regenerative Medicine, where he investigated the plasticity of the biliary epithelium during liver regeneration, and the potential of human liver progenitor cell therapy as a part of the United Kingdom Regenerative Medicine Platform (UKRMP). In 2018, Wei-Yu established his own laboratory at the Institute of Immunology and Immunotherapy, University of Birmingham and has been supported by the Medical Research Council (MRC) since 2020 to investigate the role of T cells in regulating liver epithelium regeneration. He joined the Centre for Inflammation Research, University of Edinburgh in 2021.
