Hydroxycarboxylic Acid Receptor 2 Mediates β‐hydroxybutyrate's Antiseizure Effect in Mice

Annals of Neurology, EarlyView.
A Objective The ketogenic diet, a high‐fat, low‐carbohydrate regimen, is often used to treat drug‐resistant seizures and is being studied for Alzheimer's disease and other neuropsychiatric disorders. However, its mechanism of action remains unclear. β‐hydroxybutyrate, a primary circulating ketone body produced by the ketogenic diet, may mediate its ...

Multiple Pharmacological Actions of Centrally Acting Antitussives — Do They Target G Protein-Coupled Inwardly Rectifying K+ (GIRK) Channels?

Journal of Pharmacological Sciences, 2012
Antitussive drugs have been used for decades and their modes of action are well elucidated. However, recent studies on the mechanism of their antitussive action seem to be opening a new way for discovery or development of novel drugs for intractable ...

The Mammalian Interaural Time Difference Detection Circuit Is Differentially Controlled by GABAB Receptors during Development [PDF]

, 2010
Throughout development GABAB receptors (GABABRs) are widely expressed in the mammalian brain. In mature auditory brainstem neurons, GABABRs are involved in the short-term regulation of the strength and dynamics of excitatory and inhibitory inputs, thus ...

Ethosuximide: subunit- and Gβγ-dependent blocker and reporter of allosteric changes in GIRK channels

bioRxiv
The antiepileptic drug ethosuximide (ETX) suppresses epileptiform activity in a mouse model of GNB1 syndrome, caused by mutations in Gβ1 protein, likely through the inhibition of G-protein gated K+ (GIRK) channels.

Behavioral characterization of mice lacking GIRK/Kir3 channel subunits [PDF]

Genes, Brain and Behavior, 2008
G protein‐gated inwardly rectifying K+ (GIRK/Kir3) channels mediate the postsynaptic inhibitory effects of many neurotransmitters and drugs of abuse. The lack of drugs selective for GIRK channels has hindered our ability to study their contributions to behavior.

Divergence in μ and δ opioid receptor pharmacology in neurons and antinociceptive efficacy in neuropathic pain: Insights from MP135 and CYM51010

British Journal of Pharmacology, EarlyView.
Background and purpose Opioids targeting the μ opioid receptor remain largely ineffective in neuropathic pain conditions, emphasizing the need for novel therapeutic strategies. MP135 was reported to reduce thermal nociception in naive animals by activating μ‐δ opioid receptor heteromers.

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, EarlyView.
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.

D₂ Dopamine Receptors Colocalize Regulator of G-Protein Signaling 9-2 (RGS9-2) via the RGS9 DEP Domain, and RGS9 Knock-Out Mice Develop Dyskinesias Associated with Dopamine Pathways [PDF]

, 2005
Regulator of G-protein signaling 9-2 (RGS9-2), a member of the RGS family of Gα GTPase accelerating proteins, is expressed specifically in the striatum, which participates in antipsychotic-induced tardive dyskinesia and in levodopa-induced dyskinesia. We

Sphingosine 1-phosphate receptors: do they have a therapeutic potential in cardiac fibrosis? [PDF]

, 2017
Sphingosine 1-phosphate (S1P) is a bioactive lipid that is characterized by a peculiar mechanism of action. In fact, S1P, which is produced inside the cell, can act as an intracellular mediator, whereas after its export outside the cell, it can act as ...
