There may be a temporary service outage on our Digital Library (non-newspaper) pages on Wednesday, July 30th while we update the CONTENTdm production server from version 6.5 to version 6.8. This means that the Digital Collections may be temporarily unavailable on July 30th. We plan to have all services restored Thursday, July 31st. Thank you for your patience.
α-Conotoxin MII blocks nicotine-stimulated dopamine release in rat striatal synaptosomes
Activation of presynaptic nicotinic acetylcholine receptors (nAChRs) can induce the release of neurotransmitters such as dopamine and norepinephrine in the CNS. Accumulating evidence suggests that distinct nAChR subtypes are involved; however, it has been difficult to determine the subunit composition of these receptors, in part because of the lack of a sufficient variety of selective nAChR ligands. We present experimental data that at least two different nAChR complexes are involved in dopamine release, one of which has an α3/β2 subunit interface.
