Cholinergic modulation of dopamine overflow in the rat neostriatum: A fast cyclic voltammetric study in vitro [PDF]
Stimulus-evoked dopamine overflow in rat neostriatal slices was determined using fast cyclic voltammetry. The dopamine efflux induced by intrastriatal stimulation increased with stimulus intensity and was found to be enhanced by more than 100% upon ...

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

Radioprotective effect of lidocaine on neurotransmitter agonist-induced secretion in irradiated salivary glands. [PDF]
Previously we verified the radioprotective effect of lidocaine on the function and ultrastructure of salivary glands in rabbits. However, the underlying mechanism of lidocaine's radioprotective effect is unknown.

Structural determinants at the M2 muscarinic receptor modulate the RGS4-GIRK response to pilocarpine by impairment of the receptor voltage sensitivity. [PDF]
Membrane potential controls the response of the M2 muscarinic receptor to its ligands. Membrane hyperpolarization increases response to the full agonist acetylcholine (ACh) while decreasing response to the partial agonist pilocarpine.

RGS4 regulates partial agonism of the M2 muscarinic receptor-activated K+ currents. [PDF]
Partial agonists are used clinically to avoid overstimulation of receptor-mediated signalling, as they produce a submaximal response even at 100% receptor occupancy.

SPLICEIT Fluorescent Sensor for Integrating Dopamine Release with Cellular Resolution
“Single‐chain protein‐based ligand indication through a chimerically‐engineered integrator tool” (SPLICEIT) is a G‐protein coupled receptor‐based sensor design that leaves a permanent fluorescent mark. We show dopamine detection in primary cultured neurons with a fourfold signal increase normalized to an mCherry (mCh) marker.

A Cholinergic Synaptically Triggered Event Participates in the Generation of Persistent Activity Necessary for Eye Fixation [PDF]
An exciting topic regarding integrative properties of the nervous system is how transient motor commands or brief sensory stimuli are able to evoke persistent neuronal changes, mainly as a sustained, tonic action potential firing.

Muscarinic receptor oligomerization [PDF]
G protein-coupled receptors (GPCRs) have been classically described as monomeric entities that function by binding in a 1:1 stoichiometric ratio to both ligand and downstream signalling proteins.

New and developing non-adrenoreceptor small molecule drugs for the treatment of asthma [PDF]
Introduction: Inhaled corticosteroids (ICS) alone or in combination with an inhaled long-acting beta2-agonist (LABA) are the preferred long-term treatment for adults and adolescents with symptomatic asthma.
