Structurally similar allosteric modulators of α7 nicotinic acetylcholine receptors exhibit five distinct pharmacological effects. [PDF]
Activation of nicotinic acetylcholine receptors (nAChRs) is associated with the binding of agonists such as acetylcholine to an extracellular site that is located at the interface between two adjacent receptor subunits.

Bispyridinium Compounds Inhibit Both Muscle and Neuronal Nicotinic Acetylcholine Receptors in Human Cell Lines. [PDF]
Standard treatment of poisoning by organophosphorus anticholinesterases uses atropine to reduce the muscarinic effects of acetylcholine accumulation and oximes to reactivate acetylcholinesterase (the effectiveness of which depends on the specific ...

Changes in conformation and subcellular distribution of alpha(4)beta(2) nicotinic acetylcholine receptors revealed by chronic nicotine treatment and expression of subunit chimeras [PDF]
Chronic exposure to nicotine, as occurs during tobacco smoking, is one of several factors that have been reported to cause an upregulation of neuronal nicotinic acetylcholine receptors (nAChRs).

Nicotine Addiction: Neurobiology and Mechanism
Nicotine, primary component of tobaco produces craving and withdrawal effect both in humans and animals. Nicotine shows a close resemblance to other addictive drugs in molecular, neuroanatomical and pharmacological, particularly the drugs which enhances ...

The role of neuronal nicotinic acetylcholine receptors in central cardiovascular regulation. [PDF]
The central effect of nicotine on cardiovascular regulation has been extensively studied. However, due to its unselective nature for nicotinic acetylcholine receptors (nAChR) the involvement of specific nAChRs at sites in the brain, in central nervous ...

Several studies showed clearly that the mammalian central nervous system possess nicotinic receptors. Recently, using membrane receptor binding studies the regional distribution of 3H-nicotine and/or H-acetylcholine binding sites in the human brain has ...

Loop B is a major structural component of the 5-HT3 receptor [PDF]
The 5-HT3 receptor belongs to a family of therapeutically important neurotransmitter-gated receptors whose ligand binding sites are formed by the convergence of six peptide loops (A-F).

Silent agonists for α7 nicotinic acetylcholine receptors
We discuss models for the activation and desensitization of α7 nicotinic acetylcholine receptors (nAChRs) and the effects of efficacious type II positive allosteric modulators (PAMs) that destabilize α7 desensitized states.

Evolution of vertebrate nicotinic acetylcholine receptors
Background Many physiological processes are influenced by nicotinic acetylcholine receptors (nAChR), ranging from neuromuscular and parasympathetic signaling to modulation of the reward system and long-term memory.
