Monocytes and macrophages in atherogenesis

Area of Science:

• Cardiovascular Research
• Immunology
• Cell Biology

Background:

• Monocytes and macrophages are central to atherosclerosis development, influencing plaque growth and stability.
• The metabolic and phenotypic heterogeneity of myeloid cells is increasingly recognized.
• This review focuses on recent advancements in understanding these cell types in atherogenesis.

Purpose of the Study:

• To review current literature on monocyte and macrophage subsets in atherosclerosis.
• To highlight the contribution of distinct myeloid cell subtypes to atherogenesis.
• To explore the role of myelopoiesis mediators.

Main Methods:

• Literature review of recent studies on monocyte and macrophage biology.
• Analysis of phenotypic and metabolic characteristics of myeloid cell subsets.
• Synthesis of findings related to cardiovascular disease pathogenesis.

Main Results:

• Monocytes differentiate into diverse, long-lived macrophages in circulation.
• Specific monocyte and macrophage subtypes differentially impact plaque development.
• Novel characterizations of these subtypes and myelopoiesis mediators are emerging.

Conclusions:

• Understanding monocyte and macrophage phenotypes is key to developing new therapies.
• Targeting these cells may help manage atherosclerotic plaque growth and stability.
• Further research into myeloid cell regulators is essential for cardiovascular disease treatment.
