dc.description.abstract | Activation of the TRPM8 ion channel in sensory nerve endings produces a sensation of pleasant coolness. Here we show that inflammatory mediators such as bradykinin and histamine inhibit TRPM8 in intact sensory nerves, but do not do so through conventional signalling pathways. The G-protein subunit Gα q instead binds to TRPM8 and when activated by a Gq-coupled receptor directly inhibits ion channel activity. Deletion of Gα q largely abolished inhibition of TRPM8, and inhibition was rescued by a Gα q chimaera whose ability to activate downstream signalling pathways was completely ablated. Activated Gα q protein, but not GÎ 2Î 3, potently inhibits TRPM8 in excised patches. We conclude that Gα q pre-forms a complex with TRPM8 and inhibits activation of TRPM8, following activation of G-protein-coupled receptors, by a direct action. This signalling mechanism may underlie the abnormal cold sensation caused by inflammation. © 2012 Macmillan Publishers Limited. All rights reserved. | - |
