Studies on the nervous control of photophores from deep-sea luminescent fish, are mainly restricted to a pharmacological approach. For example, the light organs, called photophores, isolated from <i>Argyropelecus hemygimnus</i> and <i>Maurolicus muelleri</i> show a much higher sensitivity to adrenaline than to noradrenaline. According to these results and other information in different species, catecholamines are considered as main neurotransmitters triggering bioluminescence in deep-sea fishes. The present work is a study of the nervous control of the isolated photophores from two Stomiid fishes, <i>Chauliodus sloani</i> (the viperfish) and <i>Stomias boa</i> (the dragonfish) with the aim to determine the nature of the nervous control by pharmacological, biochemical and morphological approaches.Results show that, although the photophores of both species are sensitive to catecholamines, adrenaline is present in larger amount than noradrenaline in the light organs of <i>C. sloani</i>. Both catecholamines have different immunoreactive (IR) sites, noradrenaline showing a very diffuse localization as compared to adrenaline in <i>C. sloani</i>. On the contrary, only adrenaline is detected in the photocytes chamber and nerves innervating the photophore in <i>S. boa</i>. Knowing that the majority of dragonfishes exhibit a luminescent chin barbel, we also investigated the presence of catecholamines in this specific tissue in <i>S. boa</i>. Immunohistology reveals the presence of adrenaline within the tissue forming the chin barbel; adrenaline–IR is found in the connective tissue surroundings two group of muscle fibers and blood vessels in the stem but also around the multiple blood vessels located within the barbel bulb.Our results strongly support the adrenergic control of light emission in bioluminescent stomiid fishes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Luminescence control of Stomiidae photophores","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Chauliodus sloani; Stomias boa; bioluminescence control; Catecholamines;Pharmacology; Immunohistology","OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2019-06-04","DateCreate":"2019-05-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000461000600002","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.acthis.2018.10.001"},"refs":null,"anarec":{"AnaID":311441,"PubliDate":2019,"Pagination":"7-15","XtraPublOfAnaID":null,"ISBN":null,"Volume":"121","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":262479,"SerRR":"Acta Histochemica: Jena.
