Genetics of Sensory Mechanotransduction

Abstract: The molecular mechanisms for the transduction of light and chemical signals in animals are fairly well understood. In contrast, the processes by which the senses of touch, balance, hearing, and proprioception are transduced are still largely unknown. Biochemical approaches to identify transduction components are difficult to use with mechanosensory systems, but genetic approaches are proving more successful. Genetic research in several organisms has demonstrated the importance of cytoskeletal, extracellular, a… Show more

“…It should be useful and efficient to bring the prowess of yeast genetics to bear on the dissection of Yvc1p. The discovery of MS in Yvc1p and its further investigation may reveal a unifying principle of how Trp-family channels serve to detect osmotic pressure or other physical forces (1). A basic principle derived from the research on MscL and MscS is that these prokayrotic channels detect stretch forces directly transmitted from the lipid bilayer.…”

“…M echanosensitive (MS) ion channels, those that respond directly to mechanical forces, are generally believed to underlie the detection of touch, texture, balance, vibration, limb location, and osmotic pressure (1). In eukaryotes, several types of channels have been associated with mechanosensation, including the ENaC-like ''degenerins'' (2), the two-pore-domain K ϩ channels TREK and TRAAK (3), and several members of a class of channels called Trps (after transient receptor potential, the founding member in Drosophila phototransduction).…”

“…Members of the degenerin family of epithelial sodium channels (DEG/ENaC) are involved in many aspects of sensory signaling, including mechanosensory responses in the touch cells of C. elegans, responses in mammalian mechanoreceptors, salt and sour taste in mice, and proton responses in sensory afferents [113][114][115][116]. In regard to thermosensory signaling, in vitro recordings find that many of these channels are potentiated by cold temperatures [117].…”

“…Outre l'étude des modalités de la réponse cellulaire endothéliale et la découverte de l'identité des gènes répondant au stimulus méca-nique in vivo, une question fascinante concerne les bases molécu-laires de la mécanotransduction endothéliale. Dans la plupart des mécanorécepteurs, comme les soies sensorielles de drosophile ou les cellules ciliées de l'oreille interne de vertébré, on considère que l'élément pivot de la machinerie mécanotransductionelle est un canal ionique directement activé par le stimulus mécanique [1,2]. L'influx d'ions à travers le canal transductionnel dépolarise la membrane et active diverses réponses cellulaires.…”

“…
La mécanotransduction, processus par lequel les cellules d'un organisme convertissent les stimulus méca-niques de leur environnement en message électrique, biochimique, ou génétique, est essentielle aux fonctions sensorielles telles que l'audition, le toucher, ou la nociception [1,2]. Néanmoins, les mécanorécepteurs de l'oreille interne et de l'épiderme ne détiennent pas le monopole mécanotransductionnel chez l'animal.
