Cholinergic Receptors in Cognitive Disorders [PDF]
Abstract:Cholinergic receptors (muscarinic subtypes M1 and M2, and putative nicotinic binding) have been examined in the hippocampus obtained at autopsy from a variety of patients with cognitive disorders (Alzheimer's, Parkinson's, and Huntington's diseases, Down's Syndrome and alcoholic dementia) and compared with neurologically normal controls and ...

Effect of gallamine on cholinergic receptors [PDF]
Gallamine triethiodide causes tachycardia thought to be due to a specific vagolytic action. Recently, Brown and Crout have shown that gallamine may cause increased inotropic and chronotropic activity due to the release of catecholamines from cardiac sympathetic nerves.

Acetylcholine and cholinergic receptors [PDF]
This review provides a distillate of the advances in knowledge about the neurotransmitter functions of acetylcholine over the 50-year period between 1967 and 2017, together with incremental information about the cognate nicotinic and muscarinic acetylcholine receptors, and some brief comments on possible advances in the near future.

Adrenergic and Cholinergic Receptors of Cerebral Microvessels [PDF]
The presence of α- and β-adrenergic and muscarinic cholinergic receptors in cerebral microvessels of the rat and pig was assessed by ligand binding techniques. The results demonstrate the presence of specific binding to α 2 - and β-adrenergic receptors but no appreciable specific binding to α

This study shows that (a) the slopes of dose-response curves of bromoacetylcholine (BrACh) and acetylcoline (ACh) were the same; (b) the dose-response curves of BrACh to contract superfused chick biventer cervicis and frog rectus abdominis muscles were shifted to the right by d-tubocurarine in a parallel fashio; and (c) the responses of BrACh were not ...

Cholinergic receptors in aging and Alzheimer's disease
Although Alzheimer's disease (AD) is a disorder involving multiple neurotransmitter systems, the basal forebrain cholinergic system (Ch system) is severely and consistently affected in this condition. In both animals and man, the nature of age-associated alterations in the Ch system is unclear. In addition, available studies of cholinergic receptors in

Muscarinic cholinergic receptors in rabbit retina
Abstract Binding sites with high affinity and specificity for [3 H]-quinuclidinyl benzilate are present in rabbit retinal homogenates. Only one set of binding sites was detected with an apparent dissociation constant of 2.13 times 10−10 M and a density of 59.2 fmol mg−1 of protein.

Biological Functions of Keratinocyte Cholinergic Receptors
Human epidermal keratinocytes possess cholinergic enzymes, which synthesize and degrade acetylcholine, and express both nicotinic and muscarinic classes of cholinergic receptors on their cell surfaces. These receptors bind acetylcholine and initiate cellular response.
