Contribution of glial inwardly rectifying potassium (Kir) channels to potassium buffering in insect neural systems

open access: yesiScience
Summary: There is a paucity of information pertaining to the fundamental roles of glia in insect central nervous system (CNS) function and in the maintenance of ionic gradients. Inward rectifier potassium (Kir) channels are known to drive K+ buffering in

Somatic cell reprogramming for Parkinson's disease treatment

open access: yesIbrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

Expression of inwardly rectifying potassium channels (GIRKs) and beta-adrenergic regulation of breast cancer cell lines

open access: yesBMC Cancer, 2004
Background Previous research has indicated that at various organ sites there is a subset of adenocarcinomas that is regulated by beta-adrenergic and arachidonic acid-mediated signal transduction pathways.

Recent advances in the pathogenesis and drug actions in periodic paralyses and related channelophaties

open access: yesFrontiers in Pharmacology, 2011
The periodic paralysis(PP) are rare autosomal-dominant disorders associated to mutations in the skeletal muscle sodium, calcium and potassium channel genes characterized by muscle fiber depolarization with un-excitability, episodes of weakness 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.

Determination of the subunit stoichiometry of an inwardly rectifying potassium channel

open access: yesNeuron, 1995
Inwardly rectifying K+ channels are distantly related to their voltage-gated counterparts and possess a structural motif of only two putative transmembrane segments in each subunit. They are formed by the assembly of an unknown number of subunits. We have examined the subunit stoichiometry of a strongly rectifying K+ channel, IRK1, by linking together ...

In Vitro Reconstruction of Axonal Heat Sensing with a Photothermal Nerve‐on‐a‐Chip

open access: yesSmall, EarlyView.
A photothermal nerve‐on‐a‐chip platform is presented that enables precise, localized heating of sensory axons with simultaneous electrical recording. The system reveals millisecond‐scale dynamics of heat‐evoked neural activity and provides a new approach to study how temperature‐dependent ion channel behavior is translated into axonal firing.

G-protein mediated trafficking of inwardly rectifying potassium channels [PDF]

open access: yes, 2008
Understanding the mechanisms which regulate trafficking and surface expression of membrane-associated proteins is crucial to understanding their function in a physiological context.

A molecular toolbox for rapid generation of viral vectors to up- or down-regulate in vivo neuronal gene expression

open access: yesFrontiers in Molecular Neuroscience, 2011
We introduce a molecular toolbox for manipulation of neuronal gene expression in vivo. The toolbox includes promoters, ion channels, optogenetic tools, fluorescent proteins and intronic artificial microRNAs. The components are easily assembled into adeno-

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

open access: yesThe 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.
