Myeloid cells in cardiovascular organs.

Area of Science:

• Cardiovascular Biology
• Immunology
• Cell Biology

Background:

• Myeloid cells exhibit diverse phenotypes, influencing cardiovascular disease (CVD) progression.
• Phenotypic heterogeneity arises from varying cell sources and macrophage plasticity.
• Tissue-resident macrophages are vital for homeostasis, while monocyte-derived cells can exacerbate cardiac damage.

Purpose of the Study:

• To review the neutrophil and macrophage supply chain.
• To explore myeloid cell heterogeneity in atherosclerosis and ischemic heart disease.
• To identify potential therapeutic targets for modulating myeloid cell function in CVD.

Main Methods:

• Literature review of myeloid cell biology in cardiovascular disease.
• Analysis of cellular sources and phenotypic plasticity of macrophages.
• Examination of neutrophil and macrophage roles in atherosclerosis and ischemic heart disease.

Main Results:

• Myeloid cell heterogeneity significantly impacts cardiovascular health and disease.
• Distinct roles of tissue-resident versus monocyte-derived macrophages in cardiac function and pathology.
• Emerging evidence suggests therapeutic potential in targeting myeloid cell flux and phenotypes.

Conclusions:

• Modulating myeloid cell populations offers a promising therapeutic avenue for cardiovascular diseases.
• Further research is needed to identify optimal cell subsets and drug targets for safe and effective treatment.
• Understanding the neutrophil and macrophage supply chain is crucial for advancing CVD therapies.
