Abstract:
The emerging understanding of macrophage subsets and their functions in the atherosclerotic plaque has led to the consensus that M1 macrophages are pro-atherogenic while M2 macrophages may promote plaque stability, primarily though their tissue repair and anti-inflammatory properties. As such, modulating macrophage function to promote plaque stability is an exciting therapeutic prospect. This review will outline the involvement of the different macrophage subsets throughout atherosclerosis progression and in models of regression. It is evident that much of our understanding of macrophage function comes from in vitro or small animal models and, while such knowledge is valuable, we have much to learn about the roles of the macrophage subsets in the clinical setting in order to identify the key pathways to target to possibly promote plaque stability.
Insights
Macrophages play key roles in atherosclerosis. M1 types promote disease, while M2 types aid plaque stability through repair and anti-inflammatory actions, offering therapeutic potential.
Area of Science:
- Cardiovascular Biology
- Immunology
- Atherosclerosis Research
Background:
- Macrophage subsets (M1 and M2) have distinct roles in atherosclerosis.
- M1 macrophages are pro-atherogenic, contributing to disease progression.
- M2 macrophages exhibit tissue repair and anti-inflammatory properties, potentially promoting plaque stability.
Purpose of the Study:
- To review the involvement of macrophage subsets in atherosclerosis progression and regression.
- To explore the therapeutic potential of modulating macrophage function for plaque stabilization.
Main Methods:
- Literature review of macrophage subset functions in atherosclerosis.
- Analysis of findings from in vitro and small animal models.
- Discussion of clinical relevance and future research directions.
Main Results:
- M1 macrophages are consistently linked to pro-atherogenic effects.
- M2 macrophages demonstrate potential for promoting plaque stability and repair.
- Current understanding largely stems from preclinical models.
Conclusions:
- Targeting macrophage function represents a promising therapeutic strategy for atherosclerosis.
- Further research is needed to elucidate macrophage subset roles in the clinical setting.
- Identifying key pathways is crucial for developing effective plaque stabilization therapies.
