Activation of Muscarinic M1 Acetylcholine Receptors Induces Long-Term Potentiation in the Hippocampus [PDF]
, 2015 Muscarinic M1 acetylcholine receptors (M1Rs) are highly expressed in the hippocampus, and their inhibition or ablation disrupts the encoding of spatial memory.

Physiological functions of the cholinergic system in immune cells
Journal of Pharmacological Sciences, 2017 T and B cells, macrophages and dendritic cells (DCs) all express most of the components necessary for a functional cholinergic system. This includes choline acetyltransferase (ChAT), muscarinic and nicotinic acetylcholine (ACh) receptors (mAChRs and ...

Carbachol‐induced reverse transformation of Chinese hamster ovary cells transfected with and expressing the m5 muscarinic acetylcholine receptor [PDF]
FEBS Letters, 1989 Reverse transformation was induced in Chinese hamster ovary (CHO) cells transfected with and stably expressing the m5 subtype of the muscarinic acetylcholine receptor when stimulated with the muscarinic agonist, carbachol. Atropine, a muscarinic antagonist, blocked the carbachol‐stimulated reverse transformation.

Expression and Function of the Cholinergic System in Immune Cells
Frontiers in Immunology, 2017 T and B cells express most cholinergic system components—e.g., acetylcholine (ACh), choline acetyltransferase (ChAT), acetylcholinesterase, and both muscarinic and nicotinic ACh receptors (mAChRs and nAChRs, respectively).

Food Frontiers, Volume 7, Issue 1, January 2026.ABSTRACT Intestinal health could be affected by intestinal motility, which is controlled by the enteric nervous system. In this study, we found that α‐ketoglutarate (AKG) inhibits intestinal motility and improves intestinal permeability, accompanied by an increased count of intestinal flora.

Muscarinic agonist, (±)-quinuclidin-3-yl-(4-fluorophenethyl)(phenyl)carbamate: High affinity, but low subtype selectivity for human M1 – M5 muscarinic acetylcholine receptors [PDF]
Bioorganic & Medicinal Chemistry Letters, 2019 Novel quinuclidinyl N-phenylcarbamate analogs were synthesized, and binding affinities at M1-M5 muscarinic acetylcholine receptor (mAChR) subtypes were determined using Chinese hamster ovary (CHO) cell membranes stably expressing one specific subtype of human mAChR. Although not subtype selective, the lead analog (±)-quinuclidin-3-yl-(4-fluorophenethyl)
