1 Differential regulation of mesolimbic alpha 3/alpha 6 beta 2 and alpha 4 beta 2 nicotinic acetylcholine receptor sites and function after long-term oral nicotine to monkeys. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
2 Chronic nicotine treatment, which led to plasma nicotine levels in the range of smokers, significantly increased nucleus accumbens alpha4beta2* nAChR sites and function compared with control. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
3 Chronic nicotine treatment, which led to plasma nicotine levels in the range of smokers, significantly increased nucleus accumbens alpha4beta2* nAChR sites and function compared with control. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
4 Thus, these data are distinct from previous results in striatum in which the same nicotine treatment paradigm decreased striatal alpha3/alpha6beta2* nAChR sites and function. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
5 The finding that long-term nicotine treatment selectively modulates alpha4beta2* and not alpha3/alpha6beta2* nAChR expression in primate nucleus accumbens is consistent with the results of studies in nicotinic receptor mutant mice implicating the alpha4beta2* nAChR subtype in nicotine-mediated addiction. Nicotine cholinergic receptor, nicotinic, alpha polypeptide 7 Mus musculus
