Endothelial mechanobiology in atherosclerosis

Area of Science:

• Cardiovascular biology
• Mechanobiology
• Endothelial cell function

Background:

• Cardiovascular disease (CVD) is a leading global cause of mortality.
• The vascular endothelium, lining blood vessels, is crucial for homeostasis.
• Atherosclerosis development is linked to mechanical forces on the vascular wall.

Approach:

• Review of current research on endothelial mechanobiology.
• Analysis of how disturbed blood flow influences atherosclerotic lesion formation.
• Examination of endothelial cells' (ECs) mechanosensory mechanisms and adaptive responses.

Key Points:

• Disturbed blood flow patterns (low shear stress, recirculation, oscillation) in arteries preferentially promote atherosclerotic lesion formation.
• Endothelial cells possess sophisticated mechanosensory systems to detect and respond to mechanical forces.
• ECs modulate their functions based on mechanical cues for adaptive responses.

Conclusions:

• Endothelial mechanobiology is central to understanding atherosclerosis.
• Targeting EC mechanobiology may offer novel therapeutic strategies for CVD.
• Further research can guide the development of treatments to slow or reverse atherosclerosis progression.
