Nicotine 10-18 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 110-115 18583454-1 2008 Nicotine treatment has long been associated with alterations in alpha4beta2(*) nicotinic acetylcholine receptor (nAChR) expression that modify dopaminergic function. Nicotine 0-8 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 79-111 18583454-1 2008 Nicotine treatment has long been associated with alterations in alpha4beta2(*) nicotinic acetylcholine receptor (nAChR) expression that modify dopaminergic function. Nicotine 0-8 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 113-118 18583454-2 2008 However, the influence of long-term nicotine treatment on the alpha6beta2(*) nAChR, a subtype specifically localized on dopaminergic neurons, is less clear. Nicotine 36-44 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 77-82 18583454-3 2008 Here we used voltammetry, as well as receptor binding studies, to identify the effects of nicotine on striatal alpha6beta2(*) nAChR function and expression. Nicotine 90-98 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 126-131 18583454-7 2008 In contrast, in nicotine-treated rats, alpha6beta2(*) nAChR blockade elicited a similar pattern of dopamine release with nonburst and burst firing. Nicotine 16-24 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 54-59 18583454-9 2008 (125)I-alpha-CtxMII competition studies in striatum of knockout mice showed that nicotine treatment decreased the alpha6alpha4beta2(*) subtype but increased the alpha6(nonalpha4)beta2(*) nAChR population. Nicotine 81-89 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 187-192 18583454-10 2008 These data indicate that alpha6beta2(*) nAChR-evoked dopamine release in nicotine-treated rats is mediated by the alpha6(nonalpha4)beta2(*) nAChR subtype and suggest that the alpha6alpha4beta2(*) nAChR and/or alpha4beta2(*) nAChR contribute to the differential effect of higher frequency stimulation on dopamine release under control conditions. Nicotine 73-81 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 40-45 18583454-10 2008 These data indicate that alpha6beta2(*) nAChR-evoked dopamine release in nicotine-treated rats is mediated by the alpha6(nonalpha4)beta2(*) nAChR subtype and suggest that the alpha6alpha4beta2(*) nAChR and/or alpha4beta2(*) nAChR contribute to the differential effect of higher frequency stimulation on dopamine release under control conditions. Nicotine 73-81 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 140-145 18583454-10 2008 These data indicate that alpha6beta2(*) nAChR-evoked dopamine release in nicotine-treated rats is mediated by the alpha6(nonalpha4)beta2(*) nAChR subtype and suggest that the alpha6alpha4beta2(*) nAChR and/or alpha4beta2(*) nAChR contribute to the differential effect of higher frequency stimulation on dopamine release under control conditions. Nicotine 73-81 cholinergic receptor nicotinic alpha 2 subunit Rattus norvegicus 140-145 18583454-10 2008 These data indicate that alpha6beta2(*) nAChR-evoked dopamine release in nicotine-treated rats is mediated by the alpha6(nonalpha4)beta2(*) nAChR subtype and suggest that the alpha6alpha4beta2(*) nAChR and/or alpha4beta2(*) nAChR contribute to the differential effect of higher frequency stimulation on dopamine release under control conditions.
