Grid cell spatial tuning reduced following systemic muscarinic receptor blockade.
Grid cells of the medial entorhinal cortex exhibit a periodic and stable pattern of spatial tuning that may reflect the output of a path integration system. This grid pattern has been hypothesized to serve as a spatial coordinate system for navigation and memory function. The mechanisms underlying the generation of this characteristic tuning pattern remain poorly understood. Systemic administra...
متن کاملDelineating muscarinic receptor functions.
A as the first chemical molecule to be established as a neurotransmitter, has attracted enduring interest from researchers over several decades. However, deciphering all of the physiological manifestations associated with actions of this molecule has been difficult, and many mysteries of cholinergic neurotransmission still remain to be resolved. Like many other neurotransmitters, the actions of...
متن کاملMuscarinic receptor oligomerization
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. However, in recent years, a growing number of studies has supported the hypothesis that these receptors can interact to form dimers and higher order oligomers although the molecular basis for these int...
متن کاملFunctional characterization of CCHamide and muscarinic acetylcholine receptor signalling in Drosophila melanogaster
The insect neuropeptides CCHamide-1 and -2 are recently discovered peptides that probably occur in all arthropods. Here, we used immunocytochemistry, in situ hybridization, and quantitative PCR (qPCR), to localize the two peptides in the fruitfly Drosophila melanogaster. We found that CCHamide-1 and -2 were localized in endocrine cells of the midgut of larvae and adult flies. These endocrine ce...
متن کاملTime-dependent modulation of muscarinic m1/m3 receptor signalling by local anaesthetics.
BACKGROUND Signalling of several G-protein-coupled receptors of the Gq/11 family is time-dependently inhibited by local anaesthetics (LAs). Since LA-induced modulation of muscarinic m1 and m3 receptor function may explain their beneficial effects in clinical practice, such as decreased postoperative cognitive dysfunction or less bronchoconstriction, we studied how prolonged exposure affects mus...
