Efferocytosis in atherosclerosis.

Area of Science:

• Cardiovascular Science
• Immunology
• Cell Biology

Background:

• Cardiovascular disease, a leading global cause of death, is often driven by atherosclerotic plaque progression.
• Dysfunctional efferocytosis, the clearance of dead cells, is an emerging key factor in atherosclerosis development.
• Impaired efferocytosis leads to dead cell accumulation, enlarging necrotic cores and increasing plaque instability.

Purpose of the Study:

• To review programmed cell death types in atherosclerotic plaques.
• To highlight the role of efferocytosis in cardiovascular physiology.
• To discuss efferocytosis failure mechanisms in cardiovascular and cardiometabolic diseases.

Main Methods:

• Review of scientific literature on efferocytosis, atherosclerosis, and programmed cell death.
• Analysis of mechanisms underlying efferocytosis dysfunction in cardiovascular disease.
• Exploration of therapeutic strategies targeting efferocytosis.

Main Results:

• Atherosclerotic plaques exhibit various forms of programmed cell death.
• Efferocytosis is crucial for maintaining cardiovascular health by clearing cellular debris.
• Efferocytosis failure contributes to plaque progression and instability in atherosclerosis, myocardial infarction, and diabetes.

Conclusions:

• Dysfunctional efferocytosis is a significant contributor to cardiovascular disease pathogenesis.
• Understanding efferocytosis failure provides insights into plaque development and rupture.
• Targeting efferocytosis presents a potential therapeutic avenue for cardiovascular and cardiometabolic diseases.
