Evaluation of antipsychotic properties of M4 muscarinic acetylcholine receptor agonists in mice

Proceedings for Annual Meeting of The Japanese Pharmacological Society, 2021
M 1 and/or M 4 muscarinic acetylcholine receptors are suggested to be involved in the pathogenesis and treatment of schizophrenia. To validate the antipsychotic potential of M 4 receptor activation, we evaluated the antipsychotic properties of the ...

Postural Orthostatic Tachycardia Syndrome Is Associated With Elevated G‐Protein Coupled Receptor Autoantibodies

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background The etiology of postural orthostatic tachycardia syndrome (POTS) is yet to be established. The disorder is often misdiagnosed as chronic anxiety or a panic disorder because the autonomic failure in these patients is not severe.

Interactions between the neuromodulatory systems and the amygdala: exploratory survey using the Allen Mouse Brain Atlas. [PDF]

, 2013
Neuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system.

Stimulation of the muscarinic receptor M4 regulates neural precursor cell proliferation and promotes adult hippocampal neurogenesis

Development, 2023
Cholinergic signaling plays a crucial role in the regulation of adult hippocampal neurogenesis; however, the mechanisms by which acetylcholine mediates neurogenic effects are not completely understood.

Functional Activation of G-Proteins Coupled With Muscarinic Acetylcholine Receptors in Rat Brain Membranes

Journal of Pharmacological Sciences, 2014
.: The functional activation of Gi/o proteins coupled to muscarinic acetylcholine receptors (mAChRs) was investigated with the conventional guanosine-5′-O-(3-[35S]thio)triphosphate ([35S]GTPγS) binding assay in rat brain membranes.

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.

Mechanistic insights into allosteric structure-function relationships at the M1 muscarinic acetylcholine receptor [PDF]

, 2014
Background: Selective and potent positive allosteric modulators (PAMs) of the M1 mAChR have been recently described. Results: Use of structural analogues and mutagenic mapping identified the mechanistic basis for increased PAM activity.
