Relationship between membrane phosphatidylinositol-4,5-bisphosphate and receptor-mediated inhibition of native neuronal M channels [PDF]
, 2005 The relationship between receptor-induced membrane phosphatidylinositol-4'5'-bisphosphate (PIP2) hydrolysis and M-current inhibition was assessed in single-dissociated rat sympathetic neurons by simultaneous or parallel recording of membrane current and ...

Effects of tetrahydroaminoacridine on M1 and M2 muscarine receptors
Neuroscience Letters, 1988 Tetrahydroaminoacridine (THA) has been reported to improve the memory of persons with Alzheimer's disease, but its mechanism of action is uncertain. We found that clinically effective concentrations, 0.03-0.3 microM, readily inhibit acetylcholinesterase and butyrylcholinesterase from rabbit hippocampal tissue in artificial cerebrospinal fluid (CSF) at ...

Effects of novel muscarinic M3 receptor ligand C1213 in pulmonary arterial hypertension models. [PDF]
, 2016 Pulmonary hypertension (PH) is a complex disease comprising a pathologic remodeling and thickening of the pulmonary vessels causing an after load on the right heart ventricle that can result in ventricular failure. Triggered by oxidative stress, episodes

Involvement of muscarinic receptors in psychomotor hyperactivity in dopamine-deficient mice
Molecular Brain, 2022 Dopamine-deficient (DD) mice exhibit psychomotor hyperactivity that might be related to a decrease in muscarinic signaling. In the present study, muscarinic acetylcholine receptor M2 (CHRM2) density decreased in the cortex in DD mice. This is significant

Mapping the druggable allosteric space of G-protein coupled receptors: a fragment-based molecular dynamics approach. [PDF]
, 2010 To address the problem of specificity in G-protein coupled receptor (GPCR) drug discovery, there has been tremendous recent interest in allosteric drugs that bind at sites topographically distinct from the orthosteric site. Unfortunately, structure-based

Presynaptic M1 muscarinic cholinoceptors mediate inhibition of excitatory synaptic transmission in the hippocampus in vitro [PDF]
, 1990 The effects of the cholinoceptor agonist, carbachol (CCh), were examined in the rat hippocampal slice preparation. Intracellular recordings from CA1 pyramidal neurones revealed that CCh (1–3 μM) inhibited excitatory postsynaptic responses evoked by ...
