The main characteristics are muscular hypotonia, failure to thrive and feeding problems in infancy, which switch to hyperphagia in early childhood and continue into adulthood. Due to hyperphagia, the risk of developing morbid obesity is high without treatment. PWS is considered a hypothalamic disease, and within the hypothalamus the arcuate nucleus (AC) is of central importance for controlling metabolism, hunger, and satiety. The AC has been studied in several animal models as well as in humans, including PWS. The function of AC is regulated by several neuropeptides and proteins produced within the central nervous system such as oxytocin, orexin, tachykinins as well as the hypothalamic hormones, regulating the adeno-hypophyseal hormones, also acting as neurotransmitters. Additionally, there are many peripheral hormones among which insulin, leptin, adiponectin, ghrelin, and glucagon-like peptide (GLP-1) are the most important. High levels of adiponectin and ghrelin have consistently been reported in PWS, but dysregulation and deviating levels of many other factors and hormones have also been demonstrated in both individuals with PWS and in animal models. In this review, we focus on the role of AC and peptides and proteins produced within the central nervous system in the regulation of hunger and satiety in PWS.<\/jats:p>","DOI":"10.3390\/cimb47030192","type":"journal-article","created":{"date-parts":[[2025,3,14]],"date-time":"2025-03-14T07:02:16Z","timestamp":1741935736000},"page":"192","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Role of the Arcuate Nucleus in Regulating Hunger and Satiety in Prader-Willi Syndrome"],"prefix":"10.3390","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3980-1927","authenticated-orcid":false,"given":"Charlotte","family":"H\u00f6ybye","sequence":"first","affiliation":[{"name":"Department of Endocrinology, Karolinska University Hospital, 171 76 Stockholm, Sweden"},{"name":"Department of Molecular Medicine and Surgery, Karolinska Institutet, 171 77 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2970-8593","authenticated-orcid":false,"given":"Maria","family":"Petersson","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Karolinska University Hospital, 171 76 Stockholm, Sweden"},{"name":"Department of Molecular Medicine and Surgery, Karolinska Institutet, 171 77 Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,14]]},"reference":[{"key":"ref_1","unstructured":"Adam, M.P., Feldman, J., Mirzaa, G.M., Pagon, R.A., Wallace, S.E., and Amemiya, A.
