Abstract

Smokers often report an anxiolytic effect of cigarettes. In addition, stress‐related disorders such as anxiety, post‐traumatic stress syndrome and depression are often associated with chronic nicotine use. To study the role of the α5 nicotinic acetylcholine receptor subunit in anxiety‐related responses, control and α5 subunit null mice (α5 −/− ) were subjected to the open field activity (OFA), light–dark box (LDB) and elevated plus maze (EPM) tests. In the OFA and LDB, α5 −/− behaved like wild‐type controls. In the EPM, female α5 −/− mice displayed an anxiolytic‐like phenotype, while male α5 −/− mice were undistinguishable from littermate controls. We studied the hypothalamus–pituitary–adrenal axis by measuring plasma corticosterone and hypothalamic corticotropin‐releasing factor. Consistent with an anxiolytic‐like phenotype, female α5 −/− mice displayed lower basal corticosterone levels. To test whether gonadal steroids regulate the expression of α5, we treated cultured NTera 2 cells with progesterone and found that α5 protein levels were upregulated. In addition, brain levels of α5 mRNA increased upon progesterone injection into ovariectomized wild‐type females. Finally, we tested anxiety levels in the EPM during the estrous cycle. The estrus phase (when progesterone levels are low) is anxiolytic‐like in wild‐type mice, but no cycle‐dependent fluctuations in anxiety levels were found in α5 −/− females. Thus, α5‐containing neuronal nicotinic acetylcholine receptors may be mediators of anxiogenic responses, and progesterone‐dependent modulation of α5 expression may contribute to fluctuations in anxiety levels during the ovarian cycle.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
