Effects of mechanical ventilation on the extracellular matrix

Area of Science:

• Pulmonary medicine
• Biomedical engineering
• Cell biology

Background:

• The extracellular matrix (ECM) is crucial for lung biomechanics and function.
• ECM macromolecules regulate lung hydration, structure, inflammation, and repair.
• Mechanical ventilation can induce lung injury through complex biomechanical forces.

Purpose of the Study:

• To review the effects of mechanical ventilation on the lung extracellular matrix (ECM).
• To explore ECM organization, mechanotransduction, and interactions within the lung.
• To enhance understanding of ventilator-induced lung injury (VILI) pathophysiology.

Main Methods:

• Literature review focusing on ECM organization and mechanobiology.
• Synthesis of current knowledge on mechanical ventilation's impact on lung ECM.
• Analysis of ECM's role in cellular and tissue responses to mechanical stress.

Main Results:

• Few reviews comprehensively address mechanical ventilation's effects on the lung ECM.
• ECM plays a significant role in lung parenchyma biomechanics and VILI.
• Understanding ECM mechanotransduction is key to VILI research.

Conclusions:

• The lung ECM is a critical factor in ventilator-induced lung injury.
• Further study of the ECM is essential for improving VILI pathophysiology understanding.
• Targeting ECM-related pathways may offer therapeutic strategies for VILI.
