Acetylcholine regulates the melanogenesis of retinal pigment epithelia cells via a cAMP-dependent pathway: A non-neuronal function of cholinergic system in retina

Heliyon
The turnover rate of melanogenesis in retinal pigment epithelium (RPE) and its molecular signaling remain unclear. This study aimed to investigate the role of cholinergic signaling in the process of melanogenesis of cultured RPE cells.

Dopamine Signaling in Dorsal Versus Ventral Striatum: The Dynamic Role of Cholinergic Interneurons [PDF]

, 2011
Mesostriatal dopaminergic neurons and striatal cholinergic interneurons participate in signaling the motivational signifcance of environmental stimuli and regulate striatal plasticity. Dopamine (DA) and acetylcholine (ACh) have potent interactions within

Assessment of the molecular mechanisms of action of novel 4-phenylpyridine-2-one and 6-phenylpyrimidin-4-one allosteric modulators at the M1 muscarinic acetylcholine receptors [PDF]

, 2018
Positive allosteric modulators (PAMs) that target the M1 muscarinic acetylcholine (ACh) receptor (M1 mAChR) are potential treatments for cognitive deficits in conditions such as Alzheimer's disease and schizophrenia.

Arrestin Binding to the M2 Muscarinic Acetylcholine Receptor Is Precluded by an Inhibitory Element in the Third Intracellular Loop of the Receptor*

Journal of Biological Chemistry, 2000
Desensitization of G protein-coupled receptors (GPCRs) involves the binding of members of the family of arrestins to the receptors. In the model system involving the visual GPCR rhodopsin, activation and phosphorylation of rhodopsin is thought to convert

Interkingdom Interactions in the Gut: Ecological Mechanisms, Homeostasis, and Therapeutic Modulation

Gut Medicine, Volume 2, Issue 1, Page 23-39, March 2026.
ABSTRACT The gut microbiota constitutes a highly complex and dynamic ecosystem that profoundly influences host physiology, metabolism, and immunity. This review provides an integrative overview of the mechanisms through which gut microorganisms—particularly bacteria and fungi—interact with host cells and with each other to maintain intestinal ...

Regions of beta 2 and beta 4 responsible for differences between the steady state dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 neuronal nicotinic receptors [PDF]

, 1995
We constructed chimeras of the rat beta 2 and beta 4 neuronal nicotinic subunits to locate the regions that contribute to differences between the acetylcholine (ACh) dose-response relationships of the alpha 3 beta 2 and alpha 3 beta 4 receptors ...

Embryonic chick heart expresses multiple muscarinic acetylcholine receptor subtypes. Isolation and characterization of a gene encoding a novel m2 muscarinic acetylcholine receptor with high affinity for pirenzepine.

Journal of Biological Chemistry, 1991
Muscarinic acetylcholine receptors (mAChR) are G protein-coupled receptors which are highly conserved across mammalian species. Chick cardiac mAChR, however, have been shown to be pharmacologically, immunologically, and biochemically distinct from m2 ...

G Protein–Coupled Receptors in Olfactory Signaling and Related Disorders: Mechanisms and Therapeutic Implications

Sensory Neuroscience, Volume 2, Issue 1, March 2026.
This schematic highlights GPCRs as the central hub of olfactory signaling in health and disease. The central GPCR shows odorant activation and downstream pathways. Surrounding quadrants illustrate four GPCR‐mediated themes: odor perception and adaptation, mucosal immunity and regeneration, memory consolidation via neural circuits, and GPCR‐related ...
