Summary
Lower CX3CL1/Fractalkine levels in hepatitis B virus (HBV) patients correlate with advanced liver fibrosis. This chemokine may serve as a prognostic biomarker for predicting fibrosis progression in HBV infection.
Area of Science:
- Hepatology
- Immunology
- Virology
Background:
- Hepatitis B virus (HBV) infection can lead to severe liver disease, including fibrosis, cirrhosis, and cancer.
- CX3CL1/Fractalkine is a chemokine involved in immune responses against HBV infection.
Purpose of the Study:
- To quantify CX3CL1/Fractalkine plasma levels in HBV patients.
- To assess the association between CX3CL1/Fractalkine and liver fibrosis severity in HBV infection.
Main Methods:
- Blood plasma samples analyzed from HBV, HCV, autoimmune hepatitis patients, and healthy donors.
- CX3CL1/Fractalkine concentrations measured using xMAP technology.
Main Results:
- HBV-infected patients exhibited lower CX3CL1/Fractalkine concentrations compared to controls.
- Significantly reduced CX3CL1/Fractalkine levels were observed in HBV patients with severe fibrosis/cirrhosis versus those with no/mild fibrosis.
- CX3CL1/Fractalkine concentrations were significantly associated with the stage of liver fibrosis in HBV infection.
Conclusions:
- Decreased CX3CL1/Fractalkine concentrations are linked to increased risk of progressive liver fibrosis in HBV infection.
- CX3CL1/Fractalkine shows potential as a prognostic biomarker for predicting liver fibrosis development and progression.

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

01:23Cirrhosis I: Introduction
28
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

01:24Cirrhosis II: Pathophysiology
42
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to...
