Nicotine 17-25 immunoglobulin (CD79A) binding protein 1 Mus musculus 108-115 27157710-1 2016 Studies with heterologous expression systems have shown that the alpha4beta2 nicotinic acetylcholine receptor (nAChR) subtype can exist in two stoichiometries (with two [(alpha4)2(beta2)3] or three [(alpha4)3(beta2)2] copies of the alpha subunit in the receptor pentamer) which have different pharmacological and functional properties and are differently regulated by chronic nicotine treatment. Nicotine 376-384 immunoglobulin (CD79A) binding protein 1 Mus musculus 65-71 27157710-5 2016 For cortex exposure to chronic nicotine elicited an increase in receptor density measured by (3)H-epibatidine binding, an increase in the alpha4 and beta2 protein levels, and an increase in beta2/alpha4 subunit ratio, that indicates an increased proportion of receptors with the (alpha4)2(beta2)3 stoichiometry. Nicotine 31-39 immunoglobulin (CD79A) binding protein 1 Mus musculus 138-144 27157710-5 2016 For cortex exposure to chronic nicotine elicited an increase in receptor density measured by (3)H-epibatidine binding, an increase in the alpha4 and beta2 protein levels, and an increase in beta2/alpha4 subunit ratio, that indicates an increased proportion of receptors with the (alpha4)2(beta2)3 stoichiometry. Nicotine 31-39 immunoglobulin (CD79A) binding protein 1 Mus musculus 196-202 27157710-5 2016 For cortex exposure to chronic nicotine elicited an increase in receptor density measured by (3)H-epibatidine binding, an increase in the alpha4 and beta2 protein levels, and an increase in beta2/alpha4 subunit ratio, that indicates an increased proportion of receptors with the (alpha4)2(beta2)3 stoichiometry. Nicotine 31-39 immunoglobulin (CD79A) binding protein 1 Mus musculus 196-202 27102349-5 2016 The most prevalent is the widely expressed alpha4-containing (alpha4*) subtype which mediates reward and is strongly implicated in nicotine dependence. Nicotine 131-139 immunoglobulin (CD79A) binding protein 1 Mus musculus 62-69 27102349-10 2016 Receptor expression showed a strong positive correlation with daily nicotine dose, suggesting that alpha4* nAChR expression levels are age-specific and may contribute to the propensity to self-administer nicotine. Nicotine 68-76 immunoglobulin (CD79A) binding protein 1 Mus musculus 99-106 27102349-10 2016 Receptor expression showed a strong positive correlation with daily nicotine dose, suggesting that alpha4* nAChR expression levels are age-specific and may contribute to the propensity to self-administer nicotine. Nicotine 204-212 immunoglobulin (CD79A) binding protein 1 Mus musculus 99-106 25043731-1 2014 Extrasynaptic GABAA receptors, often identified as those containing both alpha4 and delta subunits, demonstrate super-sensitivity to GABA and are involved in tonic inhibitory processes regulating activity within mesolimbocortical circuitry. gamma-Aminobutyric Acid 14-18 immunoglobulin (CD79A) binding protein 1 Mus musculus 73-89 26961950-3 2016 In midbrain dopaminergic (DA) neurons from mice containing fluorescent nAChR subunits, menthol alone increased the number of alpha4 and alpha6 nAChR subunits, but this upregulation did not occur in midbrain GABAergic neurons. Menthol 87-94 immunoglobulin (CD79A) binding protein 1 Mus musculus 125-131 26961950-4 2016 Thus, chronic menthol produces a cell-type-selective upregulation of alpha4* nAChRs, complementing that of chronic nicotine alone, which upregulates alpha4 subunit-containing (alpha4*) nAChRs in GABAergic but not DA neurons. Menthol 14-21 immunoglobulin (CD79A) binding protein 1 Mus musculus 69-75 26961950-4 2016 Thus, chronic menthol produces a cell-type-selective upregulation of alpha4* nAChRs, complementing that of chronic nicotine alone, which upregulates alpha4 subunit-containing (alpha4*) nAChRs in GABAergic but not DA neurons. Menthol 14-21 immunoglobulin (CD79A) binding protein 1 Mus musculus 149-155 26961950-4 2016 Thus, chronic menthol produces a cell-type-selective upregulation of alpha4* nAChRs, complementing that of chronic nicotine alone, which upregulates alpha4 subunit-containing (alpha4*) nAChRs in GABAergic but not DA neurons. Menthol 14-21 immunoglobulin (CD79A) binding protein 1 Mus musculus 149-155 26961950-4 2016 Thus, chronic menthol produces a cell-type-selective upregulation of alpha4* nAChRs, complementing that of chronic nicotine alone, which upregulates alpha4 subunit-containing (alpha4*) nAChRs in GABAergic but not DA neurons. Nicotine 115-123 immunoglobulin (CD79A) binding protein 1 Mus musculus 149-155 26961950-4 2016 Thus, chronic menthol produces a cell-type-selective upregulation of alpha4* nAChRs, complementing that of chronic nicotine alone, which upregulates alpha4 subunit-containing (alpha4*) nAChRs in GABAergic but not DA neurons. Nicotine 115-123 immunoglobulin (CD79A) binding protein 1 Mus musculus 149-155 26961950-7 2016 In neuroblastoma cells transfected with fluorescent nAChR subunits, exposure to 500 nm menthol alone also increased nAChR number and favored the formation of (alpha4)3(beta2)2 nAChRs; this contrasts with the action of nicotine itself, which favors (alpha4)2(beta2)3 nAChRs. Menthol 87-94 immunoglobulin (CD79A) binding protein 1 Mus musculus 159-165 26961950-9 2016 Thus, menthol stabilizes lower-sensitivity alpha4* and alpha6 subunit-containing nAChRs, possibly by acting as a chemical chaperone.

Nicotine 191-199 immunoglobulin (CD79A) binding protein 1 Mus musculus 153-170 21406211-6 2011 (1) MPTP treatment transiently increased nAChR alpha7 (after last injection of MPTP 3 and 24 h), alpha4 and beta2 (24 h) mRNA expression in the substantia nigra (SN) and striatum. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine 4-8 immunoglobulin (CD79A) binding protein 1 Mus musculus 97-113 19720621-1 2010 Recent studies suggest that high-affinity neuronal nicotinic acetylcholine receptors (nAChRs) containing alpha4 and beta2 subunits (alpha4beta2*) functionally interact with G-protein-coupled dopamine (DA) D(2) receptors in basal ganglia.

Nicotine 155-163 immunoglobulin (CD79A) binding protein 1 Mus musculus 41-47 12713636-11 2003 Our results indicate that alpha4-containing nAChRs exert a tonic control on striatal basal dopamine release, which is mediated by a heterogeneous population of nAChRs.

Nicotine 0-8 immunoglobulin (CD79A) binding protein 1 Mus musculus 145-151 12021063-0 2002 Steroids modulate the expression of alpha4 integrin in mouse blastocysts and uterus during implantation. Steroids 0-8 immunoglobulin (CD79A) binding protein 1 Mus musculus 36-42 12021063-8 2002 Immunolocalization of protein expression of alpha4 and beta1 integrin subunits indicate that steroids modulate the expression of alpha4beta1 integrin receptor in the mouse blastocyst as well as the uterus and that a differential expression is observed with exposure to progesterone and estrogen.

Nicotine 210-218 immunoglobulin (CD79A) binding protein 1 Mus musculus 38-44 11927835-8 2002 These results suggest that genetically determined differences in sensitivity to nicotine may be explained, in part, by variability associated with at least two of the neuronal nicotinic receptor genes, alpha4 and alpha6. Nicotine 80-88 immunoglobulin (CD79A) binding protein 1 Mus musculus 202-219 11434511-3 2001 A polymorphism in the coding portion of the alpha4 gene was found (1587A to G) which should result in a threonine/alanine substitution at position 529 (T529A).
