چکیده

The TRPN1 ion channel has a role in both hearing and bristle mechanosensation in fruit flies and in proprioception in nematodes. In this issue of Neuron, two papers present evidence that TRPN1 is also required for proprioception in fruit fly larvae and that it is a bona fide mechanoreceptor channel for nematode feeding behavior.

Phospholipids that contain polyunsaturated fatty acids enhance neuronal cell mechanics and touch sensation.

Mechanoelectrical transduction (MeT) channels embedded in neuronal cell membranes are essential for touch and proprioception. Little is understood about the interplay between native MeT channels and membrane phospholipids, in part because few techniques are available for altering plasma membrane composition in vivo. Here, we leverage genetic dissection, chemical complementation, and optogenetic...

A Drosophila mechanosensory transduction channel.

Mechanosensory transduction underlies a wide range of senses, including proprioception, touch, balance, and hearing. The pivotal element of these senses is a mechanically gated ion channel that transduces sound, pressure, or movement into changes in excitability of specialized sensory cells. Despite the prevalence of mechanosensory systems, little is known about the molecular nature of the tran...

Mechanosensation: Touch at the molecular level

Touch and the related sense of proprioception are the most ubiquitous, yet the least understood, of the senses. In vertebrates, the sensory terminals of touch receptors and proprioreceptors are far from the cell bodies, dispersed throughout the body and embedded in other tissues, impeding the electrophysiological recording of mechanoreceptor potentials and biochemical purification of components...

NOMPC is likely a key component of Drosophila mechanotransduction channels.

Mechanotransduction is the basis of several sensory modalities, including touch, hearing, proprioception and gravity sensation. Despite its importance to sensory processing and behavior, the molecular mechanisms underlying mechanotransduction remain to be fully understood. In particular, the identity of the ion channels serving mechanotransduction is still unknown in many species. Drosophila me...

Studies of mechanosensation using the fly.

Mechanosensation requires the transduction of mechanical stimuli into neuronal impulses. It encompasses not only the sense of touch but also proprioception and hearing. In contrast to sight, smell and taste, relatively little is known about the molecular machinery of mechanosensation. It is already clear, however, that important aspects are conserved across phyla, from Caenorhabditis elegans to...
