The cerebral distribution of this receptor is well conserved across species, with high densities in the basal ganglia, where they are expressed by GABAergic neurons. The 5-HT4 receptor is also present in the cerebral cortex, hippocampus, and amygdala, where they are carried by glutamatergic or cholinergic neurons. Outside the central nervous system, the 5-HT4 receptor is notably expressed in the gastrointestinal tract. The wide distribution of the 5-HT4 receptor undoubtedly contributes to its involvement in a plethora of functions. In addition, the modulation of this receptor influences the release of serotonin, but also the release of other neurotransmitters such as acetylcholine and dopamine. This is a considerable asset, as the modulation of the 5-HT4 receptor can therefore play a direct or indirect beneficial role in various disorders. One of the main advantages of this receptor is that it mediates a much faster antidepressant and anxiolytic action than classical selective serotonin reuptake inhibitors. Another major benefit of the 5-HT4 receptor is that its activation enhances cognitive performance, probably via the release of acetylcholine. The expression of the 5-HT4 receptor is also altered in various eating disorders, and its activation by the 5-HT4 agonist negatively regulates food intake. Additionally, although the cerebral expression of this receptor is modified in certain movement-related disorders, it is still yet to be determined whether this receptor plays a key role in their pathophysiology. Finally, there is no longer any need to demonstrate the value of 5-HT4 receptor agonists in the pharmacological management of gastrointestinal disorders.<\/jats:p>","DOI":"10.3390\/ijms25105245","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T08:03:08Z","timestamp":1715673788000},"page":"5245","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The Serotonin 4 Receptor Subtype: A Target of Particular Interest, Especially for Brain Disorders"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8792-8586","authenticated-orcid":false,"given":"V\u00e9ronique","family":"Sgambato","sequence":"first","affiliation":[{"name":"Institut des Sciences Cognitives Marc Jeannerod (ISCMJ), Unit\u00e9 Mixte de Recherche 5229 du Centre National de la Recherche Scientifique (CNRS), 69675 Bron, France"},{"name":"UFR Biosciences, Universit\u00e9 de Lyon 1, 69100 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"266","DOI":"10.1016\/j.euroneuro.2008.12.005","article-title":"Spatiotemporal expression of tryptophan hydroxylase isoforms in murine and human brain: Convergent data from Tph2 knockout mice","volume":"19","author":"Gutknecht","year":"2009","journal-title":"Eur.
