Abstract:
Kv7 K+-channel subunits differ in their apparent affinity for PIP2 and are differentially expressed in nerve, muscle, and epithelia in accord with their physiological roles in those tissues. To investigate how PIP2 affinity affects the response to physiological stimuli such as receptor stimulation, we exposed homomeric and heteromeric Kv7.2, 7.3, and 7.4 channels to a range of concentrations of the muscarinic receptor agonist oxotremorine-M (oxo-M) in a heterologous expression system. Activation of M1 receptors by oxo-M leads to PIP2 depletion through Gq and phospholipase C (PLC). Chinese hams

Abstract:
Background: The Kv7 (KCNQ) subfamily of voltage-gated potassium channels consists of 5 members (Kv7.1-5) each showing characteristic tissue distribution and physiological roles. Given their functional heterogeneity, Kv7 channels represent important pharmacological targets for the development of new drugs for neuronal, cardiovascular and metabolic diseases. <p> Objective: In the present manuscript, we focus on describing the pharmacological relevance and potential therapeutic applications of drugs acting on neuronally-expressed Kv7.2/3 channels, placing particular emphasis on the differen

Abstract:
The M-type K+ current (M-current), encoded by Kv7.2/3 (KCNQ2/3) K+ channels, plays a critical role in regulating neuronal excitability because it counteracts subthreshold depolarizations. Here we have characterized the functions of pre- and postsynaptic M-channels using a novel Kv7.2/3 channel opener, NH6, which we synthesized as a new derivative of N-phenylanthranilic acid. NH6 exhibits a good selectivity as it does not affect Kv7.1 and IKS K+ currents as well as NR1/NR2B, AMPA, and GABAA receptor-mediated currents. Superfusion of NH6 increased recombinant Kv7.2/3 current amplitude (EC50 = 18

Abstract:
KV7 channels control neuronal excitability. We show that these channels are expressed in muscle afferents and generate currents that are blocked by XE991 and bradykinin (BK). The XE991 block suggests that KV7 current comprises KV7.2/3 and KV7.5 channels. The BK inhibition of KV7 channels may explain how BK activates the exercise pressor reflex (EPR). Retigabine can enhance KV7 current, which could help control the inappropriately activated EPR in patients with cardiovascular disease.

Bien que les nerfs périphériques adultes conservent la capacité de se régénérer, la restauration fonctionnelle reste souvent décevante en cas de lésions traumatiques ou de neuropathies périphériques. De plus, une mauvaise récupération est souvent associée au développement de douleurs neuropathiques chroniques. La protéine translocatrice mitochondriale (protéine de translocation, TSPO, 18 kDa) et les canaux potassiques Kv7.2/3 (KCQN2/3) voltage-dépendants sont deux cibles prometteuses pour favoriser la régénération des nerfs périphériques et la récupération fonctionnelle, et pour prévenir la ch
