Nicotine: from molecular mechanisms to behaviour

Wonnacott, Susan, Sidhpura, Nimish, Balfour, David JK·2005·Current Opinion in Pharmacology

Abstract

The addictive potential of nicotine is clearly recognized by the tenacity of tobacco smoking for most users, and has prompted extensive psychopharmacological studies in animals. In parallel, the interaction of nicotine with the many subtypes of its eponymous receptor has been the focus of molecular and cellular investigations. More recently, a convergence of these approaches has been stimulated by the generation of transgenic animals, which facilitates analysis of the impact of molecular changes on behaviour. Nicotine, like other addictive drugs including psychomotor stimulants, promotes dopamine release in the nucleus accumbens. This transmitter system has been a major focus of both neurochemical and behavioural investigations, although recently the pre-eminence of this system in nicotine dependence has been challenged. Complexities in the brain circuitry (including the subdivisions of the nucleus accumbens) and differences between behavioural models help to rationalise the current controversy.

  • Bungarotoxin-insensitive nAChR subtypes, including the α4β2-containing subtype, have been extensively implicated in the behavioral effects of nicotine, including dependence-related effects such as nicotine self-administration and neurotransmitter release (dopamine).

    “Of the various types of nAChRs that exist in the central nervous system (CNS), members of the so-called bungarotoxin-insensitive subtypes, which are composed of alpha and beta subunits and includes the ubiquitous α4β2-containing subtype, have been extensively implicated in the behavioral effects of nicotine, including its dependence-related effects such as nicotine self-administration and neurotra”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
