Liver tissue remodelling, driven by chronic inflammation and hepatocellular carcinoma (HCC), involves extracellular matrix (ECM) changes. This review details fibrosis, cirrhosis, and therapeutic cytokine modulation in liver disease progression.

Area of Science:

  • Hepatology
  • Cell Biology
  • Pathology

Background:

  • Tissue remodelling is a fundamental biological process affecting tissue structure and function.
  • It occurs in both physiological states (e.g., pregnancy) and pathological conditions (e.g., wound healing).
  • Liver remodelling is particularly relevant in chronic hepatitis and hepatocellular carcinoma (HCC).

Purpose of the Study:

  • To review liver tissue remodelling in the context of chronic inflammation and HCC.
  • To explore the role of extracellular matrix (ECM) deposition and turnover in liver fibrosis and cirrhosis.
  • To evaluate the impact of cytokines, including Interferon-alpha, on ECM proteolysis and their therapeutic potential.

Main Methods:

  • Review of existing literature on liver remodelling, fibrosis, cirrhosis, and HCC.

  • Analysis of the mechanisms underlying ECM alterations in liver disease.
  • Evaluation of the role of inflammatory and anti-inflammatory cytokines in modulating ECM proteolysis.

    • Main Results:

    • Altered ECM deposition and turnover are key drivers of liver fibrosis, potentially leading to cirrhosis.
    • Cytokines, such as Interferon-alpha, can modulate ECM proteolysis, offering therapeutic avenues.
    • Alterations in the liver microenvironment, including ECM and growth factors, are implicated in HCC development and invasiveness.

    Conclusions:

    • Liver remodelling is a critical process in the pathogenesis of chronic liver diseases and HCC.
    • Targeting ECM dynamics and cytokine signaling represents a promising therapeutic strategy for liver fibrosis and cancer.
    • Understanding the interplay between the microenvironment and liver disease progression is essential for developing effective treatments.
