Area of Science:
- Immunology
- Cardiology
- Cell Biology
Background:
- Cardiovascular diseases (CVDs) represent a significant global health burden, driving the need for deeper insights into disease mechanisms.
- Macrophages, central to innate immunity, are increasingly recognized for their complex roles in CVD pathogenesis.
- Understanding macrophage heterogeneity and function is crucial for developing effective CVD treatments.
Purpose of the Study:
- To provide a comprehensive overview of macrophage subpopulations, heterogeneity, and ontogeny.
- To elucidate the influence of cellular metabolism on macrophage functions in the cardiovascular system.
- To explore macrophage roles in specific cardiovascular diseases and their therapeutic potential.
Main Methods:
- Literature review focusing on macrophage biology and cardiovascular disease.
- Analysis of current research on macrophage subpopulations and their functional diversity.
- Examination of metabolic pathways impacting macrophage behavior.
Main Results:

Abstract:
Cardiovascular disease is a major cause of human morbidity and mortality. With the rising prevalence of cardiovascular diseases and their increasing economic impact on individuals and society, a deeper understanding of their pathogenesis is essential. Macrophages play the crucial role in this regulatory network as key cell types in the innate immune system. This review provides an overview of the subpopulations, heterogeneity, and ontogenetic diversity of macrophages. It emphasizes how various cellular metabolic processes influence the biological functions of macrophages. Additionally, it explores the mechanisms through which macrophages function in different cardiovascular diseases (e.g., atherosclerosis, hypertension, or myocardial infarction) and examines their potential therapeutic applications. The review also addresses the current limitations and future directions for research and therapeutic strategies involving cardiac macrophages in cardiovascular diseases.
