Summary
Macrophages are key immune cells in liver disease, showing diverse roles in inflammation and fibrosis. Targeting these hepatic macrophages offers potential for new precision medicine therapies in liver conditions like cirrhosis and HCC.
Area of Science:
- Immunology
- Hepatology
- Cell Biology
Background:
- Macrophage activation programs are increasingly understood in liver diseases, identifying them as crucial therapeutic targets.
- Clinical data links macrophage infiltration and polarization to prognosis in liver cirrhosis and hepatocellular carcinoma (HCC).
- Recent transcriptomics studies reveal macrophage heterogeneity and their dual role in hepatic inflammation, injury, and fibrosis.
Purpose of the Study:
- To review potential therapeutic targets for modulating macrophage behavior in liver diseases.
- To discuss nanoscale therapeutics designed for targeting and treating macrophages.
- To summarize knowledge on macrophage programs in chronic liver inflammation, cirrhosis, and HCC for precision medicine.
Main Methods:
- Review of cutting-edge research, including single-cell and spatial transcriptomics.
- Analysis of clinical data on macrophage infiltration and polarization.
- Synthesis of current knowledge on macrophage regulatory mechanisms and therapeutic interventions.
Main Results:
- Hepatic macrophages (Kupffer cells and monocyte-derived) exhibit significant plasticity and diversity.
- Antagonistic macrophage functions can coexist within the liver, complicating analysis of circulating markers.
- Understanding macrophage heterogeneity is vital for developing effective therapeutic strategies.
Conclusions:
- Modulating macrophage behavior presents a promising avenue for treating liver diseases.
- Nanoscale therapeutics offer novel approaches for macrophage-targeted interventions.
- Precision medicine strategies targeting specific hepatic macrophage programs could restore liver homeostasis.
