Atheromas feel the pressure: biomechanical stress and atherosclerosis

Area of Science:

• Cardiovascular Biology
• Biomedical Engineering
• Cellular Mechanobiology

Background:

• Atherosclerosis is a major cause of mortality, linked to hemodynamic variations in blood vessels.
• Atherosclerotic lesions modify the local microenvironment's biomechanics, with poorly understood molecular consequences.
• Vascular smooth muscle cells are key players in atherosclerosis development and response to biomechanical cues.

Purpose of the Study:

• To review the relationship between biomechanics, the tissue microenvironment, and cellular/molecular responses in atherosclerosis.
• To highlight the role of vascular smooth muscle cells in the context of atherosclerosis and biomechanics.

Main Methods:

• Literature review synthesizing current research on biomechanics in atherosclerosis.
• Focus on studies investigating the vascular smooth muscle cell's response to biomechanical factors.
• Analysis of the interplay between hemodynamics, tissue mechanics, and cellular signaling.

Main Results:

• Hemodynamic forces and altered tissue mechanics at specific vascular sites promote atherosclerosis.
• Atherosclerotic lesions induce biomechanical changes that impact cellular function.
• Vascular smooth muscle cells exhibit complex responses to mechanical stimuli, influencing disease progression.

Conclusions:

• Understanding the biomechanical microenvironment is essential for deciphering atherosclerosis pathogenesis.
• Further research into the mechanobiology of vascular smooth muscle cells is critical for developing effective therapies.
• Integrating biomechanical insights with molecular mechanisms offers a promising avenue for future atherosclerosis research.
