BRET-Based Approaches for Ion Channels: Emerging Applications and Future Directions. [PDF]

Arch Pharm (Weinheim)
Bioluminescence resonance energy transfer (BRET) is a versatile method for studying ligand–protein interactions. Its compatibility with high‐throughput screening and real‐time kinetics has made it widely used in drug discovery. Here, we summarize recent applications of BRET‐based methods for studying ligand binding to ion channels, highlighting key ...

Prefrontal Cortex 5-HT1A Receptor-Coupled Inwardly Rectifying Potassium Channels Decreased Seizure Susceptibility in Rat Models With Autism Spectrum Disorder. [PDF]

Neural Plast
Dysregulation of serotonin 1A receptor (5‐HT1A), a G protein‐coupled inhibitory receptor, is implicated in the pathogenesis of both autism spectrum disorder (ASD) and epilepsy. The prefrontal cortex (PFC) is particularly vulnerable to the factors that affect neuronal and synaptic development, with abnormal PFC development leading to increased epilepsy ...

Activation of GHSRs Facilitates the Excitability of Dentate Gyrus Granule Cells and Short-Term Spatial Memory via Multiple Ionic and Signaling Mechanisms. [PDF]

Adv Biol (Weinh)
Ghrelin excites the dentate gyrus (DG) granule cells via GHSR‐mediated modulation of diverse ionic channels and activation of D1R, cAMP, and EPAC2. Similarly, overnight calorie restriction alters neuronal excitability in a ghrelin‐dependent manner. Infusion of ghrelin directly into the DG improves short‐term spatial memory in the Y‐maze, providing ...

Effects of moderate static magnetic fields on voltage-gated potassium ion channels in sympathetic neuron-like PC12 cells. [PDF]

Physiol Rep
This study investigates the impact of moderate SMF on Kv channels in the sympathetic‐like plasma membrane of PC12 cells. In conclusion, moderate SMF is strongly associated with reduced current density in PC12 cells, particularly affecting Kv channels. The present study provides fundamental information on the influence of long‐term SMF exposure on the ...

Peripheral κ opioid receptor in pain and inflammation: From molecular signalling and gene expression to drug discovery

British Journal of Pharmacology, Volume 183, Issue 17, Page 5157-5189, September 2026.
The κ opioid receptor (κ receptor, KOR) is a G protein‐coupled receptor with well established roles in analgesia and immune modulation. Although historically studied primarily in the central nervous system (CNS), growing evidence indicates that κ signalling in peripheral tissues plays an important role in regulating pain, inflammation and immune ...

KCNJ4 variants disrupt inward‐rectifier potassium channel function and cause refractory epilepsy

Epilepsia, Volume 67, Issue 6, Page 3199-3210, June 2026.
Abstract Objective Epilepsy is a common neurological disorder with a strong genetic basis, most frequently arising from ion channel dysfunction. Although multiple inwardly rectifying potassium (Kir) channels have been implicated in epileptogenesis, the contribution of KCNJ4, which encodes the Kir2.3 channel, has not previously been established in human

The Role and Therapeutic Potential of Voltage‐Gated Potassium Channel Kv1.3 in Metabolism‐Related Disorders

iNew Medicine, Volume 2, Issue 2, June 2026.
ABSTRACT Over the past three decades, the global burden of common metabolic diseases such as obesity, diabetes, and atherosclerosis has steadily increased, becoming a serious public health issue that poses a major threat to human health worldwide. Potassium channels, particularly the voltage‐gated Kv1.3 subtype, serve as critical regulators of cellular

Higher sensitivity to ouabain‐induced toxicity in human induced pluripotent stem cell‐derived cardiomyocytes than human adult heart tissue despite similar Na+/K+‐ATPase pump current amplitudes

British Journal of Pharmacology, Volume 183, Issue 11, Page 3093-3110, June 2026.
Abstract Background and Purpose Human induced pluripotent stem cell‐derived cardiomyocytes (hiPSC‐CM) have gained interest as a pharmacological model but their immaturity leads to uncertainty regarding translation. We studied the key player in maintaining ionic homeostasis, the Na+/K+‐ATPase (NKA), in hiPSC‐CM.

Feedback control of excitability and high K+ induced epileptiform bursts in male rat hippocampal slices with a photocaged adenosine A1 receptor agonist

British Journal of Pharmacology, Volume 183, Issue 10, Page 2578-2591, May 2026.
Background and Purpose Adenosine is a potent regulator of neurotransmission and neuronal excitability, through activation of Gi coupled adenosine A1 receptors (A1Rs). Adenosine has gained interest as an anticonvulsant because of its endogenous involvement in ending seizure activity, but peripheral side effects require local application.
