m6A modification: a novel mechanism that regulates atherosclerosis via macrophage polarization

Area of Science:

• Vascular biology
• Immunology
• Molecular biology

Background:

• Atherosclerosis is a chronic inflammatory vascular disease.
• Macrophages are central to atherosclerosis pathology, with M1 and M2 phenotypes influencing inflammation via cytokine secretion.
• N6-methyladenosine (m6A) modification, a key RNA modification, regulates gene expression and is implicated in macrophage polarization.

Purpose of the Study:

• To review the role of macrophage polarization phenotypes in atherosclerosis progression.
• To explore the significance of m6A modifications in the context of macrophage polarization and atherosclerosis.
• To provide a theoretical basis for novel diagnostic and therapeutic strategies for atherosclerosis.

Main Methods:

• Literature review of studies on macrophage polarization in atherosclerosis.
• Analysis of research on the role of m6A modification in macrophage biology.
• Synthesis of information linking m6A, macrophage phenotypes, and atherosclerotic pathology.

Main Results:

• Different macrophage polarization states (M1/M2) differentially affect atherosclerosis.
• m6A modification is a critical regulator of macrophage polarization.
• The interplay between m6A and macrophage polarization mechanisms is intrinsically linked to atherosclerosis development.

Conclusions:

• Understanding macrophage polarization and m6A modification is crucial for comprehending atherosclerosis.
• m6A modification represents a significant factor in modulating macrophage-driven inflammation in atherosclerosis.
• Targeting m6A-dependent macrophage polarization pathways may offer novel therapeutic avenues for atherosclerosis.
