Neuromodulation of Persistent Activity and Working Memory Circuitry in Primate Prefrontal Cortex by Muscarinic Receptors

open access: yesFrontiers in Neural Circuits, 2021
Neuromodulation by acetylcholine plays a vital role in shaping the physiology and functions of cerebral cortex. Cholinergic neuromodulation influences brain-state transitions, controls the gating of cortical sensory stimulus responses, and has been shown

Position of anticholinergic drugs in the treatment of childhood asthma [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2010
Anticholinergic drugs block muscarinic effect of acetylcholine on the receptors of postjunctional membranes and so inhibit the answer of the postganglionic parasympathetic nerve.

Characterization of the positive and negative inotropic effects of acetylcholine in the human myocardium [PDF]

open access: yes, 1995
In the human isolated myocardium, acetylcholine (10−9 to 10−3 M) elicited a biphasic inotropic effect (a decrease in the lower and an increase in the higher concentration range) in atrial and a positive inotropic effect in ventricular trabeculae. However,

TLR2 and TLR4 Modulate Mouse Ileal Motility by the Interaction with Muscarinic and Nicotinic Receptors

open access: yesCells, 2022
Irritable bowel syndrome (IBS) is a chronic functional bowel disorder characterized by intestinal dysmotility. Changes in intestinal microbiota (dysbiosis) can lead to alterations in neuro-muscular functions in the gut. Toll-like receptors (TLRs) 2 and 4

Long-Term—But Not Short-Term—Plasticity at the Mossy Fiber–CA3 Pyramidal Cell Synapse in Hippocampus Is Altered in M1/M3 Muscarinic Acetylcholine Receptor Double Knockout Mice

open access: yesCells, 2023
Muscarinic acetylcholine receptors are well-known for their crucial involvement in hippocampus-dependent learning and memory, but the exact roles of the various receptor subtypes (M1–M5) are still not fully understood.

Bitopic binding mode of an M1 muscarinic acetylcholine receptor agonist associated with adverse clinical trial outcomes [PDF]

open access: yes, 2018
The realisation of the therapeutic potential of targeting the M1 muscarinic acetylcholine receptor (M1 mAChR) for the treatment of cognitive decline in Alzheimer's disease has prompted the discovery of M1 mAChR ligands showing efficacy in alleviating ...

BK Channels Regulate Contraction Secondary to M2 Muscarinic Acetylcholine Receptor Mediated Depolarization [PDF]

open access: bronzeBiophysical Journal, 2011
Airway smooth muscles (ASM) contraction is primarily mediated by M2 and M3 muscarinic acetylcholine receptors. We and others have shown that one of the functions of large conductance Ca2+- and voltage-activated (BK) potassium channel and the accessory β1 subunit is to moderate ASM excitation-contraction coupling by opposing cholinergic evoked ...

Role of Conserved Tyrosine Lid Residues in the Activation of the M2 Muscarinic Acetylcholine Receptor

open access: yesMolecular Pharmacology, 2023
The development of subtype selective small molecule drugs for the muscarinic acetylcholine receptor (mAChR) family has been challenging. The design of more selective ligands can be improved by understanding the structure and function of key amino acid residues that line ligand binding sites.

Structures of the M1 and M2 muscarinic acetylcholine receptor/G-protein complexes [PDF]

open access: yesScience, 2019
Choosing a partner G protein–coupled receptors (GPCRs) bind ligands outside the cell and trigger events inside the cell by selectively binding and activating specific G proteins. The selectivity occurs even among highly related GPCRs.

Calcium-Dependent Regulation of the Neuronal Glycine Transporter GlyT2 by M2 Muscarinic Acetylcholine Receptors

open access: yesNeurochemical Research, 2021
The neuronal glycine transporter GlyT2 modulates inhibitory glycinergic neurotransmission and plays a key role in regulating nociceptive signal progression. The cholinergic system acting through muscarinic acetylcholine receptors (mAChRs) also mediates important regulations of nociceptive transmission being the M2 subtype the most abundantly expressed ...
