Hypothesis
How is inflammation established and maintained within an atherosclerotic plaque?
Conclusion
Macrophages play diverse roles in atherosclerosis, including inflammation, lipid metabolism, and matrix degradation, with significant heterogeneity in their behavior and activation.
Supporting Evidence
- Macrophages are the most abundant immune cells in atherosclerotic plaques.
- Different macrophage phenotypes exist in various plaque locations.
- Macrophage activation is influenced by environmental signals and cytokines.
Takeaway
Macrophages are like little soldiers in our blood vessels that help fight off bad stuff, but they can also cause problems if they get too active.
Methodology
This review discusses the role of macrophage activation and phenotypic polarization in lesion formation and vulnerability in atherosclerosis.
Limitations
The review highlights the need for more studies to assess multiple markers in human and murine lesions to map macrophage heterogeneity.
