In January’s edition of o-Phenanthroline medchemexpress Nature Neuroscience, O’Hagan, Chalfie and Goodman [1] have provided direct electrophysiological evidence that somatic mechanotransduction in C. elegans is mediated by a complex of proteins previously identified in genetic screens for impaired touch sensation. Are the homologues of those proteins vital for discomfort sensation in mammals Possibly surprisingly, the balance of evidence suggests that other proteins are superior candidate noxious mechanosensors in mammals. Many forms of pain, be it in acute, inflammatory or diseaserelated conditions, are triggered by mechanical stimuli. Even so, in mammals there is incredibly small understanding from the molecular transduction process that converts mechanical stimuli into a modify in N-Acetyl-L-tryptophan Metabolic Enzyme/Protease membrane excitability. Studying mechanosensation in mammals is hampered by the diffuse and inaccessible distribution of nerve terminals in the periphery. The few studies of receptor potentials, produced utilizing extracellular recordings (mainly from Pacinian corpuscles of the cat’s mesentery), do on the other hand suggest that mechanical stimuli depolarise termini by straight gating cationic channels [2]. It is actually genetic studies in C. elegans and Drosophila which have driven forward our molecular understanding of mechanosensation in a variety of different cell varieties. The bestcharacterised method will be the body touch receptor neuron of C. elegans; over 2 decades, Martin Chalfie and coworkers have, around the basis of genetic mutant interactions, behavioural analysis and gene cloning, devised an elegantmolecular model of transduction in these cells (see Refs. three and four). Within this model no less than 9 proteins form a mechanotransduction complex with an ion channel at its core formed by MEC4 and MEC10 (members with the DEG/ ENaC ion channel superfamily) and apparently MEC6 (a paraoxonaselike protein, [5]). The complicated also includes extra and intracellular.
