beta2-Nicotinic acetylcholine receptor availability during acute and prolonged abstinence from tobacco smoking.
CONTEXT Available levels of nicotinic acetylcholine receptors containing the beta(2) subunit (beta(2)*-nAChR) are higher in recently abstinent tobacco smokers compared with participants who neverExpand

Ketamine-induced reduction in mGluR5 availability is associated with an antidepressant response: an [11C]ABP688 and PET imaging study in depression
The mechanisms of action of the rapid antidepressant effects of ketamine, an N-methyl-D-aspartate glutamate receptor antagonist, have not been fully elucidated. This study examined the effects ofExpand

Lower ß2*-nicotinic acetylcholine receptor availability in smokers with schizophrenia.
OBJECTIVE There is a strong association between cigarette smoking and schizophrenia. Nicotine's actions in the brain are mediated through nicotinic acetylcholine receptors. Those containing α(4) andExpand

Effect of a nicotine vaccine on nicotine binding to β2*-nicotinic acetylcholine receptors in vivo in human tobacco smokers.
OBJECTIVE Nicotine promotes smoking partly by binding to β2-containing nicotinic acetylcholine receptors (β2*-nAChRs) in the brain. Smoking one tobacco cigarette results in occupation of 80% ofExpand

Quantification of Smoking-Induced Occupancy of β2-Nicotinic Acetylcholine Receptors: Estimation of Nondisplaceable Binding
5-123I-iodo-85380 (123I-5-IA) is used to quantitate high-affinity nicotinic acetylcholine receptors (β2-nAChRs) on human SPECT scans. The primary outcome measure is VT/fP, the ratio at equilibriumExpand

PET imaging of α7 nicotinic acetylcholine receptors: a comparative study of [18F]ASEM and [18F]DBT-10 in nonhuman primates, and further evaluation of [18F]ASEM in humans
PurposeThe α7 nicotinic acetylcholine receptor (nAChR) is implicated in many neuropsychiatric disorders, making it an important target for positron emission tomography (PET) imaging. The first aim ofExpand
