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

Frontiers 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

Tracking Voltage-Sensitive Movements of the M2 Muscarinic Acetylcholine Receptor [PDF]

Biophysical Journal, 2015
Numerous G protein-coupled receptors (GPCRs) have been shown to change their activity levels in response to changes in membrane potential. More recently, it has been directly demonstrated that these changes in activity reflect underlying changes in conformational state.

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

Cells, 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

Porcine m2 Muscarinic Acetylcholine Receptor-Effector Coupling in Chinese Hamster Ovary Cells [PDF]

Journal of Biological Chemistry, 1995
The relationship between porcine m2 muscarinic receptor coupling to inhibition of cAMP formation and stimulation of phosphatidylinositol metabolism in Chinese hamster ovary cells was examined. Reduction of the number of receptors per cell with the slowly dissociating antagonist (-)-quinuclidinyl benzilate caused a decrease in maximal response with no ...

Effects mediated by the α7 nicotinic acetylcholine receptor on cell proliferation and migration in rat adipose-derived stem cells

European Journal of Histochemistry, 2020
Adipose-derived stem cells (ASCs) are an attractive source for regenerative medicine as they can be easily isolated, rapidly expandable in culture and show excellent in vitro differentiation potential.

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

Cells, 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.

Structural determinants at the M2 muscarinic receptor modulate the RGS4-GIRK response to pilocarpine by impairment of the receptor voltage sensitivity

Scientific Reports, 2017
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.

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

Science, 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.

Muscarinic acetylcholine receptor M1 and M3 subtypes mediate acetylcholine-induced endothelium-independent vasodilatation in rat mesenteric arteries

Journal of Pharmacological Sciences, 2016
The present study investigated pharmacological characterizations of muscarinic acetylcholine receptor (AChR) subtypes involving ACh-induced endothelium-independent vasodilatation in rat mesenteric arteries.
