A functional role for the M2 muscarinic receptor in smooth muscle contraction was investigated in isolated guinea pig ileum. Contractile responses to the muscarinic agonist oxotremorine-M (oxo-M) were measured in isolated ilea that had been pretreated with histamine (0.32 microM)

Life sciences, 62(17-18), 1659-1664 (1998-05-19)
Irreversible ligands are useful tools for investigating the function of receptor subtypes in various physiological processes. The mechanism for alkylation involves the formation of a reversible receptor complex followed by a covalent reaction. The extent of receptor alkylation is determined

Neurons of the medial septum/diagonal band of Broca (MSDB) project to the hippocampus. Muscarinic cholinergic mechanisms within the MSDB are potent modulators of hippocampal functions; intraseptal scopolamine disrupts and intraseptal carbachol facilitates hippocampus-dependent learning and memory tasks, and the associated
N Watson et al.
European journal of pharmacology, 278(3), 195-201 (1995-05-24)
Muscarinic M2 receptors account for more than half the muscarinic receptor population in smooth muscles of a number of species and yet it is the smaller M3 receptor population that mediates contraction of many of these tissues. The role of

Possible hypertension-related alterations in the nature- and receptor reserve of the muscarinic (M) receptors mediating endothelium-dependent vasodilation remain to be elucidated. Therefore we used 4-diphenylacetoxy-N-(2-chloroethyl)-piperidine (4-DAMPmustard), an irreversible M3-receptor antagonist, to estimate the receptor reserve for the methacholine (MCh)-induced endothelium-dependent
