Abstract:
This review provides a systematic and critical examination of the multifaceted roles of the CX3CL1/CX3CR1 axis in liver diseases. We emphasize its context-dependent duality-exhibiting both pro- and anti-inflammatory, pro- and anti-fibrotic, and pro- and anti-tumor functions across different etiologies. Moving beyond a binary good or bad" paradigm, we propose a contextual signaling model that integrates cellular source, microenvironmental cues, and intersecting pathways to explain its divergent roles. We synthesize recent advances in its involvement in NAFLD/NASH, viral hepatitis, autoimmune hepatitis, schistosomiasis, liver fibrosis and hepatocellular carcinoma. The review critically evaluates the axis's potential as a biomarker, discusses methodological advances and limitations in human studies, and analyzes therapeutic strategies with a focus on translational challenges. We conclude with a forward-looking perspective on precision medicine approaches targeting this axis.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...
Liver Physiology
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
