Heterozygous Deletion of Epilepsy Gene KCNQ2 Has Negligible Effects on Learning and Memory

Frontiers in Behavioral Neuroscience, 2022
Neuronal Kv7/Potassium Voltage-Gated Channel Subfamily Q (KCNQ) potassium channels underlie M-current that potently suppresses repetitive and burst firing of action potentials (APs).

Kcnv2 E151X Mouse Captures Hallmarks of KCNV2‐Associated Retinal Dystrophy

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background KCNV2‐associated retinopathy is a rare inherited retinal dystrophy caused by variants in the KCNV2 gene, leading to disrupted photoreceptor behaviour and progressive deterioration of vision. Patients have characteristic electroretinography abnormalities, including reduced cone response, delayed and reduced rod response to low light ...

Analgesic Action of Acetaminophen via Kv7 Channels

, 2022
The mechanism of acetaminophen (APAP) analgesia is at least partially unknown. Previously, we showed that the APAP metabolite N-acetyl-p-benzoquinone imine (NAPQI) activated Kv7 channels in neurons in vitro, and this activation of Kv7 channels dampened ...

The acrylamide (S)-2 as a positive and negative modulator of Kv7 channels expressed in Xenopus laevis oocytes. [PDF]

PLoS ONE, 2009
BACKGROUND: Activation of voltage-gated potassium channels of the Kv7 (KCNQ) family reduces cellular excitability. These channels are therefore attractive targets for treatment of diseases characterized by hyperexcitability, such as epilepsy, migraine ...

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

The FEBS Journal, EarlyView.
Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

The Journal of Physiology, EarlyView.
Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

A novel role of the antidepressant paroxetine in inhibiting neuronal Kv7/M channels to enhance neuronal excitability. [PDF]

Transl Psychiatry
The voltage-gated Kv7/KCNQ/M potassium channels exert inhibitory control over neuronal membrane excitability. The reduction of Kv7 channel function can improve neuronal excitability that defines the fundamental mechanism of learning and memory.

Maturation of spinal motor control through developmental changes in ion currents

The Journal of Physiology, EarlyView.
Abstract figure legend Ion channels of spinal neurons have been shown to change during development in a wide range of species. These changes occur at specific stages of development. An important developmental process is the maturation of motor control by which the body acquires new movements or refines movements already present.

Rosemary metabolite carnosic acid opens Kv1.1 via its voltage sensor and corrects Kv1.1‐linked episodic ataxia in mice

British Journal of Pharmacology, Volume 183, Issue 20, Page 6179-6198, October 2026.
Background and Purpose Episodic ataxia type 1 (EA1) is an autosomal dominant neurological disorder caused primarily by loss‐of‐function mutations in the voltage‐gated potassium channel Kv1.1 (KCNA1). Small molecules that restore Kv1.1 activity hold promise as targeted therapies for EA1, yet current pharmacological strategies remain limited ...

Multi‐omics analysis of ion channels expressed by chicken embryo vestibular type I and type II hair cells

Experimental Physiology, Volume 111, Issue 10, Page 4894-4914, 1 October 2026.
Abstract Balance and gaze rely on the rapid and accurate detection and signalling of head movements by vestibular type I and type II hair cells. Signal transduction and transmission involve several types of ion channels, which are acquired progressively during hair cell differentiation and whose identity is known only in part.
