5HT1AR-FGFR1 Heteroreceptor Complexes Differently Modulate GIRK Currents in the Dorsal Hippocampus and the Dorsal Raphe Serotonin Nucleus of Control Rats and of a Genetic Rat Model of Depression

open access: yesInternational Journal of Molecular Sciences, 2023
The midbrain raphe serotonin (5HT) neurons provide the main ascending serotonergic projection to the forebrain, including hippocampus, which has a role in the pathophysiology of depressive disorder.

Impairments in hippocampal oscillations accompany the loss of LTP induced by GIRK activity blockade

open access: yesNeuropharmacology, 2023
Learning and memory occurrence requires of hippocampal long-term synaptic plasticity and a precise neural activity orchestrated by brain network oscillations, both processes reciprocally influencing each other.

The W101C KCNJ5 Mutation Induces Slower Pacing by Constitutively Active GIRK Channels in hiPSC-Derived Cardiomyocytes

open access: yesInternational Journal of Molecular Sciences, 2023
Mutations in the KCNJ5 gene, encoding one of the major subunits of cardiac G-protein-gated inwardly rectifying K+ (GIRK) channels, have been recently linked to inherited forms of sinus node dysfunction.

Lipopolysaccharide-induced sepsis impairs M2R-GIRK signaling in the mouse sinoatrial node

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2023
Significance Altered heart rate variability (HRV), arising from impaired chronotropic response of sinoatrial node (SAN) pacemaker activity to vagal input, has been proposed as an early diagnostic marker in sepsis.

Inhibition of G protein-activated inwardly rectifying K+ channels by different classes of antidepressants. [PDF]

open access: yesPLoS ONE, 2011
Various antidepressants are commonly used for the treatment of depression and several other neuropsychiatric disorders. In addition to their primary effects on serotonergic or noradrenergic neurotransmitter systems, antidepressants have been shown to ...

Targeting GIRK Channels for the Development of New Therapeutic Agents

open access: yesFrontiers in Pharmacology, 2011
G protein-coupled inward rectifier K+ (GIRK) channels represent novel targets for the development of new therapeutic agents. GIRK channels are activated by a large number of G protein-coupled receptors (GPCRs) and regulate the electrical activity of ...

Reduced GABA-B/GIRK-mediated regulation of the VTA following a single exposure to cocaine [PDF]

open access: yes, 2012
In this paper, Arora and colleagues expand on their previous work on GIRK channels in the ventral tegmental area (VTA) presenting evidence that a single exposure to cocaine reduces inhibitory GABAergic transmission to dopamine (DA) neurons in the ventral

Evidence for a Functional Interaction between Integrins and G Protein-activated Inward Rectifier K+ Channels [PDF]

open access: yes, 1998
Heteromultimeric G protein-activated inward rectifier K+ (GIRK) channels, abundant in heart and brain, help to determine the cellular membrane potential as well as the frequency and duration of electrical impulses. The sequence arginine-glycine-aspartate

Selective Inhibition of Pulmonary Vein Excitability by Constitutively Active GIRK Channels Blockade in Rats

open access: yesInternational Journal of Molecular Sciences, 2023
Pulmonary veins (PV) are the main source of ectopy, triggering atrial fibrillation. This study investigated the roles of G protein-coupled inwardly rectifying potassium (GIRK) channels in the PV and the left atrium (LA) of the rat.

Pharmacological Characterization of 5-HT1A Autoreceptor-Coupled GIRK Channels in Rat Dorsal Raphe 5-HT Neurons.

open access: yesPLoS ONE, 2015
G protein-activated inwardly rectifying potassium (GIRK) channels in 5-HT neurons are assumed to be principal effectors of 5-hydroxytryptamine 1A (5-HT1A) autoreceptors, but their pharmacology, subunit composition and the role in regulation of 5-HT ...
