In secondo luogo il selenio, entrando nella costituzione delle glutatione perossidasi e della tioredoxina reduttasi (enzimi deputati alla degradazione del perossido di idrogeno (acqua ossigenata) che si forma durante la biosintesi degli ormoni tiroidei e che attraverso la modificazione di antigeni tiroidei può favorire l'iniziazione o la progressione di un processo tiroiditico) è anche implicato nella protezione della cellula tiroidea dal danno ossidativo e dalla progressiva fibrosi ghiandolare che ne conseguirebbe<sup id="cite_ref-Duthoit_2001_15-0" class="reference"><a href="#cite_note-Duthoit_2001-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-Burek_2008_16-0" class="reference"><a href="#cite_note-Burek_2008-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup>. È stato ipotizzato che una carenza di selenio possa contribuire all'attivazione di una tiroidite autoimmune in soggetti predisposti; si è osservata, in effetti, una correlazione inversa tra i livelli plasmatici di selenio e l'incidenza di tiroidite autoimmune in regioni con lieve deficit di selenio<sup id="cite_ref-Derumeaux_2003_17-0" class="reference"><a href="#cite_note-Derumeaux_2003-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup>. Ciò è probabilmente legato ad un'intensificazione del processo infiammatorio tiroideo, conseguente alla riduzione dell'attività degli enzimi antiossidanti selenio-dipendenti ed alla mancanza dell'effetto immunomodulatore esercitato dal selenio<sup id="cite_ref-Gartner_2003_18-0" class="reference"><a href="#cite_note-Gartner_2003-18"><span class="cite-bracket">[</span>18<span class="cite-bracket">]</span></a></sup>. In effetti la supplementazione di selenio sembra migliorare il funzionamento sia dei tireociti che delle cellule immunitarie attraverso la correzione dell'alterata interazione tra linfociti e autoantigeni tiroidei nei pazienti con deficit dell'oligoelemento<sup id="cite_ref-Schomburg_2012_19-0" class="reference"><a href="#cite_note-Schomburg_2012-19"><span class="cite-bracket">[</span>19<span class="cite-bracket">]</span></a></sup>. </p><p>Inoltre, da studi effettuati in paesi con bassi livelli di selenio nel suolo, è emerso come questo elemento abbia un ruolo chiave nel migliorare le capacità di difesa “ossidativa” di tutto l'organismo, oltre che della tiroide. La carenza di questo oligoelemento può avere infatti conseguenze anche su altri organi ed è un importante fattore di rischio per l'insorgenza di alcune patologie, neurologiche, cardiovascolari ed anche per il diabete mellito<sup id="cite_ref-McCann_2011_20-0" class="reference"><a href="#cite_note-McCann_2011-20"><span class="cite-bracket">[</span>20<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-Fairweather_2011_21-0" class="reference"><a href="#cite_note-Fairweather_2011-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup>. Gravi carenze di selenio sono, infatti, state associate a diverse malattie, quali la <a href="/wiki/Malattia_di_Kashin-Beck" title="Malattia di Kashin-Beck">malattia di Kashin-Beck</a>, un'osteoartropatia endemica descritta in regioni selenio-deficitarie del <a href="/wiki/Tibet" title="Tibet">Tibet</a> e la <a href="/wiki/Malattia_di_Keshan" title="Malattia di Keshan">malattia di Keshan</a>, una cardiomiopatia endemica giovanile descritta in alcune regioni della Cina che insorge in soggetti con deficit di selenio infettati dal virus <i>Coxsackie B</i>. </p><p>Altri studi hanno evidenziato che una carenza di selenio provoca anche una depressione dell'attività microbicida dei granulociti neutrofili. Proprio a causa di questo suo effetto sui granulociti neutrofili e su elementi del sistema immunitario, uno studio del gennaio 2007 ha dimostrato il suo ruolo nella diminuzione della carica virale nell'HIV. Nel 1986 è stato scoperto un nuovo aminoacido contenente questo elemento: la selenocisteina, cioè una cisteina che al posto dello zolfo ha un atomo di selenio, che sembra formarsi in seguito a una modifica post-traduzionale dell'aminoacido originale in circa venti proteine umane di fondamentale rilevanza. Una carenza di selenio in persone sane è relativamente rara. Essa può verificarsi in pazienti con funzione intestinale gravemente compromessa, in pazienti sottoposti a nutrizione parenterale totale, in pazienti gravemente malnutriti o affetti da gravi patologie croniche. Altri soggetti a rischio sono le popolazioni dipendenti da fonti agricole in suoli particolarmente poveri di selenio. </p><p>Per assumere una quantità giornaliera adeguata di Selenio, salvo casi specifici, è sufficiente una dieta sana ed equilibrata, in particolare ricca di latte, yoghurt, uova, cereali e, in particolare, noci e piselli.<sup id="cite_ref-NIH_1-1" class="reference"><a href="#cite_note-NIH-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>La dose giornaliera raccomandata di selenio nell'individuo adulto di entrambi i sessi è di 55 microgrammi al giorno<sup id="cite_ref-NIH_1-2" class="reference"><a href="#cite_note-NIH-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>; <style data-mw-deduplicate="TemplateStyles:r140554517">.mw-parser-output .chiarimento{background:#ffeaea;color:#444444}.mw-parser-output .chiarimento-apice{color:#EE0700}@media screen{html.skin-theme-clientpref-night .mw-parser-output .chiarimento{background:rgba(179,36,36,0.21);color:inherit}html.skin-theme-clientpref-night .mw-parser-output .chiarimento-apice{color:#b32424}}@media screen and (prefers-color-scheme:dark){html.skin-theme-clientpref-os .mw-parser-output .chiarimento{background:rgba(179,36,36,0.21);color:inherit}html.skin-theme-clientpref-os .mw-parser-output .chiarimento-apice{color:#b32424}}</style><span class="chiarimento" title="Queste informazioni non sono comprovate da fonti attendibili.">in gravidanza e durante la fase di allattamento la dose raccomandata sale rispettivamente a 60 e 70 microgrammi al giorno</span><sup class="noprint chiarimento-apice" title="Queste informazioni non sono comprovate da fonti attendibili.">[<i><a href="/wiki/Wikipedia:Uso_delle_fonti" title="Wikipedia:Uso delle fonti">senza fonte</a></i>]</sup> <sup id="cite_ref-22" class="reference"><a href="#cite_note-22"><span class="cite-bracket">[</span>22<span class="cite-bracket">]</span></a></sup>; l'assunzione prolungata di più di 400 microgrammi al giorno può provocare una intossicazione da selenio (selenosi).
