Downstream Signaling of Muscarinic M<sub>4</sub> Receptors Is Regulated by Receptor Density and Cellular Environment. [PDF]
ABSTRACT Multiple muscarinic M4 receptor modulators are currently advancing in clinical development for the treatment of positive symptoms in schizophrenia, including agonists and positive allosteric modulators. Considering the importance of comprehending M4 receptor pharmacology for these therapeutic applications, this study investigates M4 receptor ...

Nicotinic Acetylcholine Receptor Pathways in Cancer: From Psychiatric Clues to Therapeutic Opportunities. [PDF]
ABSTRACT Background The prevalence of cancer poses significant challenges to treatment, largely because of drug resistance along with other side effects. Current studies have been investigating the growth factors more than other biologic tumor features, such as neurobiologic features.

All muscarinic acetylcholine receptors (M1-M5) are expressed in murine brain microvascular endothelium [PDF]
AbstractClinical and experimental studies indicate that muscarinic acetylcholine receptors are potential pharmacological targets for the treatment of neurological diseases. Although these receptors have been described in human, bovine and rat cerebral microvascular tissue, a subtype functional characterization in mouse brain endothelium is lacking ...

Non-Neuronal Functions of the M2 Muscarinic Acetylcholine Receptor [PDF]
Acetylcholine is an important neurotransmitter whose effects are mediated by two classes of receptors. The nicotinic acetylcholine receptors are ion channels, whereas the muscarinic receptors belong to the large family of G protein coupled seven ...

Mir-34a-5p Mediates Cross-Talk between M2 Muscarinic Receptors and Notch-1/EGFR Pathways in U87MG Glioblastoma Cells: Implication in Cell Proliferation [PDF]
Glioblastoma (GBM) is the most aggressive human brain tumor. The high growth potential and decreased susceptibility to apoptosis of the glioma cells is mainly dependent on genetic amplifications or mutations of oncogenic or pro-apoptotic genes ...

Calcium Mobilization by Activation of M3/M5 Muscarinic Receptors in the Human Retinoblastoma
Activation of muscarinic acetylcholine receptors (mAChR) is one of the most important signal transduction pathways in the human body. In this study, we investigated the role of mAChR activation in relation to its subtypes in human retinoblastoma cell ...

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]
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.

Muscarinic M2 acetylcholine receptor distribution in the guinea-pig gastrointestinal tract [PDF]
In the enteric nervous system, acetylcholine is the most common neurotransmitter to induce gastrointestinal smooth muscle contractions. Cholinergic signaling is mediated by muscarinic acetylcholine receptors on the surface of smooth muscle cells.

Multiple Residues in the Second Extracellular Loop Are Critical for M3 Muscarinic Acetylcholine Receptor Activation [PDF]
Recent studies suggest that the second extracellular loop (o2 loop) of bovine rhodopsin and other class I G protein-coupled receptors (GPCRs) targeted by biogenic amine ligands folds deeply into the transmembrane receptor core where the binding of cis ...
