Nicotinic Acetylcholine Receptors
2003Publisher Summary This chapter deals with nicotinic acetylcholine receptors. Nicotinic acetylcholine receptors (nAChRs) are cholinergic receptors that form ligand-gated ion channels in the plasma membranes of certain neurons and on the postsynaptic side of the neuromuscular junction. As ionotropic receptors, nAChRs are directly linked to ion channels

Nicotinic receptors and schizophrenia
Current Medical Research and Opinion, 2004The incidence of smoking is very high in non-schizophrenic subjects presenting various psychiatric disorders (35 to 54%). However, the incidence of smoking is extremely high in schizophrenic patients: 80% to 90%, versus 25% to 30% of the general population. Various studies have demonstrated that the use of tobacco transiently restores the schizophrenic

Nicotine, Brain Nicotinic Receptors, and Neuropsychiatric Disorders
Archives of Medical Research, 2000Neuronal nicotinic acetylcholine receptors (nAChRs) represent a large family of ligand-gated cation channels with diverse structures and properties. In contrast to the muscular nAChRs, the physiological functions of neuronal nAChRs are not well defined to date.

Presynaptic nicotinic ACh receptors
Trends in Neurosciences, 1997Nicotinic ACh (nACh) receptors in the CNS are composed of a diverse array of subunits and have a range of pharmacological properties. However, despite the fact that they are ligand-gated cation channels, their physiological functions have not been determined.

Nicotine and Nicotinic Receptor Involvement in Neuropsychiatric Disorders
Current Topics in Medicinal Chemistry, 2004Advances in the understanding of the neurobiology of the nicotinic receptor have started to be matched by an appreciation of the potential role of these receptors in a variety of neuropsychiatric disorders. While alterations in nicotinic receptor number and/or function have been associated with such conditions as Alzheimer's disease for several years ...

Nicotine and Nicotinic Receptors; Relevance to Parkinson’s Disease
NeuroToxicology, 2002The development of nicotinic agonists for therapy in neurodegenerative disorders such as Parkinson's disease is an area currently receiving considerable attention. The rationale for such work stems from findings that reveal a loss of nicotinic receptors in Parkinson's disease brains.

Nicotinic Acetylcholine Receptor Assays
Current Protocols in Pharmacology, 1999AbstractNicotinic acetylcholine receptors (nAChRs) in peripheral tissues are localized almost exclusively to autonomic nerves and the motor end plates of striated musculature. Pharmacologic analyses of nicotinic receptor antagonist potencies can be conducted by assessing the ability of these compounds to inhibit responses elicited by preganglionic ...

Structure of Neuronal Nicotinic Receptors
2015Nicotinic acetylcholine receptors (nAChRs) are a critical component of the brain's cholinergic neurotransmission system that modulates important physiological processes and whose dysfunction has been observed in patients with neurodegenerative diseases and mental illness.

Neuronal Nicotinic Acetylcholine Receptors
1996Studies of the structure and function of neuronal nicotinic acetylcholine receptors (AChRs) evolved out of studies of muscle AChRs. This review will begin with a brief summary of muscle type AChRs because they are the archetype for studies of neuronal nicotinic AChRs in particular and ligand-gated ion channels in general.
