Apoptosis in atherosclerosis: pathological and pharmacological implications

Area of Science:

• Cell Biology
• Pathophysiology
• Pharmacology

Background:

• Apoptosis, or programmed cell death, is vital for embryonic development, tissue differentiation, and repair in eukaryotes.
• Apoptosis significantly influences pathological processes like atherosclerosis, affecting endothelial cells, vascular smooth muscle cells, and macrophages within atherosclerotic lesions.
• The atherosclerotic lesion environment contains abundant pro- and anti-apoptotic signals, influencing lesion cell accumulation and plaque stability.

Purpose of the Study:

• To review the current understanding of apoptosis in atheromatous lesions.
• To provide a background for future pharmacological research targeting apoptosis in atherosclerosis.
• To highlight the cell-specific nature of apoptosis in the context of atherosclerosis.

Main Methods:

• Review of existing literature on apoptosis in atherosclerosis.
• Analysis of the roles of pro- and anti-apoptotic signals in atherosclerotic lesions.
• Examination of the effects of apoptosis on different cell types within the lesion.

Main Results:

• Apoptosis limits cell accumulation in atherosclerotic lesions, slowing progression but potentially contributing to unstable plaques.
• Pharmacological agents for cardiovascular and lipid disorders can exhibit pro- or anti-apoptotic effects.
• Modulating apoptosis in specific cell types holds potential for developing anti-atherogenic therapies.

Conclusions:

• A comprehensive understanding of the cell-specific pathophysiology of apoptosis in atheromatous lesions is essential for developing effective pharmacological agents.
• Targeting apoptosis represents a promising avenue for novel anti-atherogenic drug development.
• Further research is needed to translate the knowledge of apoptosis in atherosclerosis into clinical applications.
