Interaction of the Xanthine Nucleotide Binding Goα Mutant with G Protein-coupled Receptors [PDF]

open access: yes, 1998
We constructed a double mutant version of the α subunit of Go that was regulated by xanthine nucleotides instead of guanine nucleotides (GoαX). We investigated the interaction between GoαX and G protein-coupled receptors in vitro.

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

The amino terminal domain of the human α7 nicotinic acetylcholine receptor subunit leads to the functional expression of human/insect receptors

open access: yesBritish Journal of Pharmacology, EarlyView.
Human α7 receptors have been characterised in terms of pharmacological properties. Insertion of the N‐terminal domain of the human α7 subunit leads to honeybee and cockroach chimeric receptors activated by ACh and inhibited by α‐Bgt. Insertion of the human cys‐loop leads to cockroach chimeric receptors modulated by PNU.

An in vivo biosensor for neurotransmitter release and in situ receptor activity. [PDF]

open access: yes, 2010
Tools from molecular biology, combined with in vivo optical imaging techniques, provide new mechanisms for noninvasively observing brain processes. Current approaches primarily probe cell-based variables, such as cytosolic calcium or membrane potential ...

Therapeutic potential of small molecules that block receptor‐induced Kv7/M‐current suppression in neuroprotection, seizures, and pain

open access: yesBritish Journal of Pharmacology, EarlyView.
Receptor‐induced Kv7/M‐current suppression increases neuronal activity and contributes to pathology of several conditions. A new class of Kv7 modulators identified in this study attenuates M‐current suppression and shows therapeutic effects. Abstract Background and Purpose Neuronal Kv7 channels generate low voltage–gated potassium currents known as the

Drugs that act on both G protein‐coupled receptors (GPCRs) and kinases: potentiation of effects, side effects and general aspects of drug pleiotropy

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background A drug designed for a specific target often interacts with multiple targets, either unintentionally or as part of its intended mechanism of action. This has been called pharmacological pleiotropy or polypharmacology. There are key endogenous ligands such as ATP, GABA and glutamate that act on various proteins in humans. Furthermore,

A photoisomerizable muscarinic antagonist. Studies of binding and of conductance relaxations in frog heart [PDF]

open access: yes, 1982
These experiments employ the photoisomerizable compound, 3,3'-bis- [alpha-(trimethylammonium)methyl]azobenzene (Bis-Q), to study the response to muscarinic agents in frog myocardium. In homogenates from the heart, trans-Bis-Q blocks the binding of [3H]-N-

Management of an uncommon complication using botulinum toxin type A following prosthetic laryngoplasty

open access: yesEquine Veterinary Education, EarlyView.
Summary An uncommon complication following prosthetic laryngoplasty was reported in a 4‐year‐old Andalusian mare. The mare was presented with a previously diagnosed left‐sided recurrent laryngeal neuropathy, after initial evaluation the mare underwent ventriculocordectomy and prosthetic laryngoplasty.

Inhibition of Subsets of G Protein-coupled Receptors by Empty Mutants of G Protein α Subunits in Go, G11, and G16 [PDF]

open access: yes, 2000
We previously reported that the xanthine nucleotide binding Goα mutant, GoαX, inhibited the activation of Gi-coupled receptors. We constructed similar mutations in G11α and G16α and characterized their nucleotide binding and receptor interaction.
