Delineating muscarinic receptor functions.
A as the first chemical molecule to be established as a neurotransmitter, has attracted enduring interest from researchers over several decades. However, deciphering all of the physiological manifestations associated with actions of this molecule has been difficult, and many mysteries of cholinergic neurotransmission still remain to be resolved. Like many other neurotransmitters, the actions of...
متن کاملNon-Neuronal Functions of the M2 Muscarinic Acetylcholine Receptor
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 transmembrane helix receptors. Beyond its function in neuronal systems, it has become evident that acetylcholine also plays an important role in non-ne...
متن کاملDelineating nice classes of nonsmooth functions
A whole spectrum of subdifferentiability properties is delineated in which various degrees of uniformity are present. Related properties are introduced for sets. Some characterizations in terms of monotonicity properties are displayed. Mathematics Subject Classification: 49J52, 46N10, 46T20.
متن کاملMuscarinic receptor oligomerization
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. However, in recent years, a growing number of studies has supported the hypothesis that these receptors can interact to form dimers and higher order oligomers although the molecular basis for these int...
متن کامل[Selective muscarinic receptor antagonists].
3ubtypes of muscarmic receptors, first hypothesized by Birdsall et al. ~ to explain the anomalous binding of cholinergic agonists to brain receptors~ were later demonstrated with the seEective muscarinic antagonist, pirenzepine 2. Interestingly, the search for selective antagonists, which usually follows the acceptance of a concept, antedated by many years the notion of heterogeneity of rmecari...
