Abstract
Nicotinic 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. nAChRs are a heterogeneous family of receptor subtypes consisting of pentameric combinations of α and β subunits, and are widely expressed throughout the central and peripheral nervous system. nAChR subtypes share a common basic structure but their biophysical and pharmacological properties depend on their subunit composition , which is therefore central to understanding receptor function in the nervous system and discovering new subtype-selective drugs. We briefly review some recent findings concerning the structure and function of nAChRs, particularly the native subtypes.

- 1.
The native subtypes are identified by their known subunits; if these are followed by an asterisk, it means that other unidentified subunits may also be present.
