GIRK Channels as Candidate Targets for the Treatment of Substance Use Disorders

open access: yesBiomedicines, 2022
Substance use disorders (SUDs) are chronic, lifelong disorders that have serious consequences. Repeated substance use alters brain function. G-protein-activated inwardly rectifying potassium (GIRK) channels are expressed widely in the brain, including ...

An inwardly rectifying K+ channel is required for patterning. [PDF]

open access: yes, 2012
Mutations that disrupt function of the human inwardly rectifying potassium channel KIR2.1 are associated with the craniofacial and digital defects of Andersen-Tawil Syndrome, but the contribution of Kir channels to development is undefined.

Regions Responsible for the Assembly of Inwardly Rectifying Potassium Channels [PDF]

open access: yesCell, 1996
Inwardly rectifying potassium channels have an important role in determining the resting potential of the cell. They are tetrameric proteins with two transmembrane segments (M1 and M2), a pore-forming loop (H5), a cytoplasmic N-terminal, and longer C-terminal domain. We have used biochemical and electrophysiological methods to identify regions required

Mechanisms of spinal glial activation in chemotherapy‐induced peripheral neuropathy: Focus on microglia and astrocytes

open access: yesIbrain, EarlyView.
Chemotherapy‐induced peripheral neuropathy (CIPN) remains a major clinical challenge, with central sensitization considered an important pathological mechanism in its occurrence and persistence. This review focuses on spinal astrocytes and microglia, systematically summarizing the pathological mechanisms of spinal glial cells involved in CIPN caused by

Gi/o protein-coupled receptors in dopamine neurons inhibit the sodium leak channel NALCN

open access: yeseLife, 2018
Dopamine (D2) receptors provide autoinhibitory feedback onto dopamine neurons through well-known interactions with voltage-gated calcium channels and G protein-coupled inwardly-rectifying potassium (GIRK) channels.

Kcnj16 knockout produces audiogenic seizures in the Dahl salt-sensitive rat

open access: yesJCI Insight, 2021
Kir5.1 is an inwardly rectifying potassium (Kir) channel subunit abundantly expressed in the kidney and brain. We previously established the physiologic consequences of a Kcnj16 (gene encoding Kir5.1) knockout in the Dahl salt-sensitive rat (SSKcnj16–/–),

Unconventional voltage sensing in an inwardly rectifying potassium channel

open access: yesJournal of General Physiology, 2021
Inwardly rectifying potassium channels are generally thought to achieve their physiological voltage dependence via an “extrinsic” mechanism involving voltage-dependent block by polyamines. A surprising finding of polyamine-independent gating of Kir4.1/Kir5.1 heteromeric channels suggests a mechanism of voltage dependence arising from interactions with ...

Accelerating virtual patient generation with a Bayesian optimization and machine learning surrogate model

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 486-494, March 2025.
Abstract The pharmaceutical industry has increasingly adopted model‐informed drug discovery and development (MID3) to enhance productivity in drug discovery and development. Quantitative systems pharmacology (QSP), which integrates drug action mechanisms and disease complexities to predict clinical endpoints and biomarkers is central to MID3.

Downregulation of Astrocytic Kir4.1 Potassium Channels Is Associated with Hippocampal Neuronal Hyperexcitability in Type 2 Diabetic Mice

open access: yesBrain Sciences, 2020
Epilepsy, characterized by recurrent seizures, affects 1% of the general population. Interestingly, 25% of diabetics develop seizures with a yet unknown mechanism. Hyperglycemia downregulates inwardly rectifying potassium channel 4.1 (Kir4.1) in cultured

Genetic deletion of laminin isoforms β2 and γ3 induces a reduction in Kir4.1 and aquaporin-4 expression and function in the retina. [PDF]

open access: yesPLoS ONE, 2011
Glial cells such as retinal Müller glial cells are involved in potassium ion and water homeostasis of the neural tissue. In these cells, inwardly rectifying potassium (Kir) channels and aquaporin-4 water channels play an important role in the process of ...
