Ion Channels in Epithelial Dynamics and Morphogenesis

Mechanosensitive ion channels mediate the neuronal sensation of mechanical signals such as sound, touch, and pain. Recent studies point to a function of these channel proteins in cell types and tissues in addition to the nervous system, such as epithelia, where they have been little studied, and their role has remained elusive. Dynamic epithelia are intrinsically exposed to mechanical forces. A response to pull and push is assumed to constitute an essential part of morphogenetic movements of epithelial tissues, for example. Mechano-gated channels may participate in sensing and responding to such forces. In this review, focusing on Drosophila, we highlight recent results that will guide further investigations concerned with the mechanistic role of these ion channels in epithelial cells.

Automated summary

Mechanosensitive ion channels play a crucial role in mediating neuronal sensation of mechanical signals such as sound, touch, and pain, and may also be involved in sensing and responding to mechanical forces in epithelial cells. Recent studies have highlighted the importance of further investigating the mechanistic role of these channels in epithelial tissues, particularly in dynamic epithelia.
