Simultaneous release of glutamate and acetylcholine from single magnocellular "cholinergic" basal forebrain neurons [PDF]
Basal forebrain (BF) neurons provide the principal cholinergic drive to the hippocampus and cortex. Their degeneration is associated with the cognitive defects of Alzheimer's disease. Immunohistochemical studies suggest that some of these neurons contain

Expression Profiles of Neuropeptides, Neurotransmitters, and Their Receptors in Human Keratocytes In Vitro and In Situ. [PDF]
Keratocytes, the quiescent cells of the corneal stroma, play a crucial role in corneal wound healing. Neuropeptides and neurotransmitters are usually associated with neuronal signaling, but have recently been shown to be produced also by non-neuronal ...

Striatal Cholinergic Interneurons Control Physical Nicotine Withdrawal via Muscarinic Receptor Signaling. [PDF]
The role of striatal cholinergic interneurons in nicotine withdrawal is explored. Inhibition of striatal cholinergic interneurons (ChIs) ameliorated nicotine‐dependent alterations in striatal neural population activity, nicotine withdrawal‐induced deficit in striatal dopamine release, and physical nicotine withdrawal.

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

Dysregulated hippocampal acetylcholine neurotransmission and impaired cognition in M2, M4 and M2/M4 muscarinic receptor knockout mice [PDF]
Among the five different muscarinic receptors that have been cloned and characterized, M2 and M4 receptors are localized both post- and presynaptically and are believed to have a pronounced autoreceptor role. The functional importance of these receptors in the regulation of acetylcholine release in the hippocampus and in cognitive processes was ...

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.

SUVN‐L3307032, A Positive Allosteric Modulator (PAM) at Muscarinic M4 Receptor for the Treatment of Neuropsychiatric Symptoms [PDF]
Abstract Background Centrally acting muscarinic acetylcholine receptor antagonists like atropine and scopolamine can induce psychosis‐like symptoms. Xanomeline, a muscarinic M1/M4 preferring agonist attenuated the effects of amphetamine (animal model for schizophrenia) in the wild‐type mice, however, such effects were absent in muscarinic M4 knockout ...

Carbachol and bradykinin elevate cyclic AMP and rapidly deplete ATP in cultured rat sympathetic neurons [PDF]
The agonists carbachol (CCh) and bradykinin (BK) and 54 mM KCl (high K+) were among the most potent stimulants of cyclic AMP (cAMP) production in cultured rat sympathetic neurons, measured with the use of a high-fidelity assay developed for small samples.

Muscarinic receptor oligomerization [PDF]
G protein-coupled receptors (GPCRs) have been classically described as monomeric entities that function by binding in a 1:1 stoichiometric ratio to both ligand and downstream signalling proteins.
