Estrogens act through nuclear and membrane receptors producing effects within hours/days or seconds/minutes, respectively. In mice, estrogen receptor alpha (ERα) is the main estrogen receptor (ER) controlling the activation of male sexual behavior. Although neuroestrogens rapidly modulate mouse sexual behavior, it is not known whether these effects involve membrane ERα (mERα). This study combines two complementary approaches to address this question. C451A-ERα mice carry an ERα that cannot signal at the membrane, while estetrol (E4) is a natural estrogen acting as an agonist on nuclear ERα but as an antagonist on membrane ERα. In wild-type males, E4 decreased the number of mounts and intromissions after 10 min. In C451A-ERα males, E4 also altered sexual performance but after 30 min. E4 did not affect time spent near the female in both wild-type and C451A-ERα mice. However, regardless of genotype, the aromatase inhibitor 1,4,6-Androstatriene-3,17-dione (ATD) decreased both sexual performance and the time spent near the female after 10 and 30 min, confirming the key role of aromatization in the rapid control of sexual behavior and motivation. In conclusion, the shift in timing at which the effect of E4 is observed in mice lacking mERα suggests a role for mERα in the regulation of rapid effects of neuroestrogens on sexual performance, thus providing the first demonstration that E4 acts as an antagonist of a mER in the brain. The persisting effect of ATD on behavior in C451A-ERα mice also suggests the implication of another ER.</p>","PeriodicalId":16535,"journal":{"name":"Journal of Neuroendocrinology","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41119886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The meeting, sponsored by the International Neuroendocrine Federation (INF), incorporated the Annual Meetings of the British Society for Neuroendocrinology (BSN), the French Society of NeuroEndocrinology (SNE), Hypothalamic Neuroscience and Neuroendocrinology Australasia (HNNA), and the Pan-American Neuroendocrine Society (PANS). Since the previous ICN in Toronto in 2018, many aspects of our everyday (scientific) lives had changed, and the COVID pandemic had resulted in the cancelation or postponement of many planned scientific meetings, or their move to online only. As a result of the different phases of the global pandemic and variant circulation, for many delegates in Glasgow this was their first face-to-face international meeting in over two years. Others had made the most of travel opening up again by also taking the opportunity to attend either or both of the RegPep24 or Kisspeptin 2022 satellite meetings, or the International Symposium of Avian Endocrinology, held just before ICN. It is noteworthy that all three of these accompanying meetings were supported financially by Journal of Neuroendocrinology, as was the 7th International Meeting on the Neuroscience of Parenting, held earlier in the summer, output from which was published in the July 2023 issue of the Journal. For ICN itself, the Programme Organising Committee, chaired by Suzanne Dickson of the University of Gothenburg, Sweden, and with representatives of all the constituent society members of the INF, assembled a full schedule of plenary talks and symposia. These invited talks were spread over the four days of the meeting and comprised a careful balance of speaker profiles, experience and geography, which has been a strong feature of previous ICN meetings. Although the meeting was planned as face-to-face by the local organisers, headed excellently by Neil Evans and Michelle Bellingham of the University of Glasgow, one eye had to be kept trained on the evolving global pandemic, which was an everpresent during much of the detailed planning process. Come the summer of 2022, travel was still difficult in some parts of the world, and these continuing issues prevented some invited speakers from attending the meeting, with some electing to deliver their talks remotely, while others were forced to withdraw and had to be replaced at short notice. Special thanks go to those international colleagues who stepped in, often at the last moment, to allow a full programme to proceed. Despite the problems experienced in the aftermath of COVID, the programme contained nine plenary speakers and 16 symposia, covering the themes of reproduction, behaviour, metabolism, stress, fluid/sodium balance, timing/circadian, neurohypophysis and development.

Because the AVPV is involved in the regulation of maternal behavior and oxytocin enhances its induction, this finding leads to the hypothesis that the female specific population of OXTR neurons in the AVPV regulates maternal behavior. To address this hypothesis, OXTR-Venus reporter mice were used to assess if expression levels of OXTR in the AVPV are changed during the postpartum period. The total number of OXTR-Venus neurons was significantly greater in postpartum dams compared to virgin females. To assess efferent projections of the AVPV-OXTR neurons, a Cre-dependent fluorescent protein (tdTomato) expressing a viral vector was injected into one side of the AVPV of female OXTR-Cre mice. Fibers expressing tdTomato were found in hypothalamic areas containing oxytocin neurons (the supraoptic and paraventricular nuclei) and the midbrain areas (the ventral tegmental area and periaqueductal gray) that are involved in the regulation of maternal motivation. To assess if activity of the AVPV-OXTR neurons is involved in the regulation of maternal behaviors, a chemogenetic approach was employed.
