GI-530159, a novel, selective, mechanosensitive two-pore-domain potassium (K_2P ) channel opener, reduces rat dorsal root ganglion neuron excitability

TREK two-pore-domain potassium (K2P ) channels play a critical role in regulating the excitability of somatosensory nociceptive neurons and are important mediators of pain perception. An understanding of the roles of TREK channels in pain perception and, indeed, in other pathophysiological conditions, has been severely hampered by the lack of potent and/or selective activators and inhibitors. In this study, we describe a new, selective opener of...
