Mechanically-gated Ion Channels

Mechanically-gated Ion Channels

Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Background:

Coronary arteries develop under significant mechanical stress.
The role of mechanosensitive ion channels in coronary artery development is largely unknown.

Purpose of the Study:

To investigate the role of the mechanosensitive ion channel PIEZO2 in coronary vasculature development and remodeling.
To understand the contribution of PIEZO2 to normal cardiac function.

Main Methods:

Analysis of PIEZO2 expression in coronary endothelial cells during development.
Characterization of mechanically activated ionic currents in Piezo2+ cells.
Examination of coronary vessel development in PIEZO2 loss-of-function mouse models and human variants.

Main Results:

PIEZO2 is expressed in specific coronary endothelial cells during a key remodeling phase.
Piezo2+ cells exhibit distinct transcriptional profiles and mechanically activated currents.
Loss of PIEZO2 function in mice and human variants leads to abnormal coronary vessel development and cardiac left ventricular hyperplasia.

Conclusions:

PIEZO2 channel function is essential for proper coronary vessel formation, integrity, and remodeling.
Defects in this mechanosensing pathway may contribute to congenital heart disease.
Mechanical cues are vital for cardiovascular development.
